The Benefits of Tissue Engineering and Regenerative Medicine

With the increasing number of patients enlisted in the transplant list, the supply of healthy organs is quite limited. This is demonstrated in the graph below:

The graph signifies that the number of patients enlisted on the transplant waitlist far surpasses the donors. This is alarming as there are so many patients whose life depends upon a new and healthy organ but organs are not available to them. 

            However, a new and growing branch of science which is known as tissue engineering is developing to propose a solution to this problem. With the help of various techniques implemented in tissue engineering, patients can receive temporary grafts until a healthy organ is available to them. 

            The various techniques and material implemented in tissue engineering to synthesize new grafts include:

·         Stem cells or regenerative medicine

·         Polymer scaffolds

·         Reprogramming or regeneration of the iPS cells

·         Amniotic fluid or the placental stem cells

·         Adult stem cells

·         Xenogenic cells

            All these methods or materials are currently being applied or being researched for implementing in the development of the graft. The importance of these materials have been discussed below:

Stem cells or regenerative medicine:

            I just cannot stop emphasizing on the importance and the greatness of the stem cells. Stem Cells are the type of cells that have the potential to develop into another tissue type. For example, the embryonic stem cells which are pluripotent, in nature, can differentiate into liver cells. Whereas the adult stem cells are the type of stem cells which are multipotent, this means their ability to divide into a germline is limited. The types of stem cells are summarized in the table below:

            Tissue engineering is a field which is involved in combining scaffolds, living cells and biologically active tissue to help a damaged tissue repair. 
            In order to accomplish this task, a scaffold which can be made from natural components like protein or an artificial component like plastic. After the synthesis of a scaffold, cells of the specific type of tissue are introduced. The scaffold usually has growth factors to facilitate the growth of tissue. After this, the implant is introduced in the human body.
            A scaffold can also be made from the patient’s own cell. The cells from the patient are taken from the body and are allowed to grow on a scaffold. This process has successfully produced a human heart, liver, lung and kidney tissue. The development of scaffolds through this technique might not cause an immune response as the cell belongs to the patients themselves. Hence, making it a great advantage. However, this technique has still not gained widespread usage in medical practice. These processes are also costly. Currently, this type of organ development is used for research purposes. The future goal is to implement this process to replace a diseased organ with an organ developed in the lab. 
The method to make a scaffold is summarized in this image:

Through the applications of these new technologies, we can develop a new organ which can serve as a “replacement” to the diseased organ until a new healthy graft is available!

Have you ever been in a situation where you had enough ice cream but still crave for more? I have been in this situation while on a beach. Beach is a nice place to relax and welcome the summer vacation. Going to a beach with friends is already very exciting and packing for the beach is more exciting. We had packed a lot of food to enjoy on the beach. There were a lot of delicious chocolate chip cookies, marshmallows, pancakes, waffles, and etc. You name it, we had it. After eating all of the food we had packed, one of my friends saw an ice cream shop. Many people were full and their “sugar cravings” was satisfied. However, half of my friends wanted to eat ice cream, including myself. This provoked a thought that why some people crave for sugar more than others? Do the genes have something to do with it?  Do we inherit the cravings we feel to eat sugar?
To investigate whether there are genes involved in the sugar cravings, an international team studied the genes of more than 6,500 Danish people where they found that the people who craved for the sugar had two variants of  FGF21. FGF21 is a gene that provides instruction for a hormone that is linked with the food regulation in rodents and the non-human primates. Additionally, the new study suggests that this hormone, secreted by the liver, modulates appetite in hormones.
  FGF21 is a short form of “Fibroblast Growth Factor 21” which is a hormone responsible for cellular metabolism and regulation. This protein inspires or motivates the body to indulge in glucose, aka, “sugar” which is then stored in the adipose, aka “fat tissue”. People with metabolic diseases are observed with high levels of FGF21. To test the hypothesis that the FGF21 hormone induces a significant amount of sugar consumption, the researchers conducted an experiment with the mice where there were mice with no FGF21 and mice with FGF21. When given a choice between a standard diet and a high sucrose diet, the mice with no FGF21 preferred a standard diet. Whereas mice with FGF21 opted for a high sucrose diet. Therefore they concluded that “the loss of FGF21 increases macronutrient-specific intake of mono-disaccharide sugars”(“FGF21 Mediates”). 
  However, this hormone has positive functions, too. This hormone in the liver tells the brain when the body does not need sugar. If we want this hormone to not misbehave with us, we need to ensure that it works right for us. That means this hormone is ought to stay happy to achieve summer weight loss goals. Here are some tips to make the FGF21 work right for you:
1.     Eat right sugars
1.     Eating right sugars
like fruit can help control the sugar cravings

Dream Genes
                                    Author runs blog

Last night, I was dreaming about a chocolate river and peppermint grass surrounding me. I was having the time of my life consuming these wonderful flavors. I was in the middle of this chocolate dream and alas the alarm went off. Then, I realized it was all because of the movie I watched the previous night, Charlie and the Chocolate Factory Dreams. Now for those who are not aware of this movie, it is an adaptation of Roald Dahl’s novel, Charlie and the Chocolate Factory, where a poor boy Charlie Bucket gets an opportunity to visit Willie Wonka’s famous chocolate factory and all these wonders relating to chocolate. Dreams are an interesting component of anyone’s sleep because they seem so unreal. It is common for people to wake up suddenly after encountering a nightmare or it is possible that many people wish to stay in their perfect dreams. There are instances where people have reported that they have seen dreams which are not closely related to their real-life. How and why do we see dreams?

            Let us talk about why we see dreams? Dreams are seen when we are in the REM stage of sleep. REM or Rapid Eye Movement is the stage of sleep where the body is resting, however, the brain is still active. Now, what happens when the brain is active? The brain thinks, rather it can be said the emotional center of the brain stimulates those weird things we perceive in the dreams. But believe it or not, our brains are recollecting the daily-scenarios we encounter and plays it to us. It is like watching the same movie again but with a different perspective. Isn’t it interesting? So those completely unrelated things we see are actually connected to our real-life. That is why many artists rely on dreams to get a different perspective on their idea. Hence, sometimes considering to sleep is a good idea to get brilliant ideas! Because our brain does a lot of work for us when it is actually resting. Many theories have been developed to explain why we dream. One of the theory is that sometimes the brain presents us dreams to escape reality through making connections of emotions and narrating a completely different story. Sometimes, we see nightmares because of excessive stress and anxiety. Perhaps the brain is trying to indicate through a nightmare that we need to go a little easy in the matters of stress.

            Now let us talk about how we see dreams. One recent study discovered the role of the Chrm1 and Chrm2 genes in making our transition from the non-REM sleep to REM sleep mode.  In simple words, non-REM sleep is a “dreamless stage of sleep” contrasting the REM stage of sleep where we normally perceive a dream. The Chrm1 and Chrm2 genes help us to transition from the non-REM stage to the REM stage. This research is important as physiatric disorders and sleep-disorders are linked. So further research in the topic matter can help us in treating the sleep disorders to help psychological disorders.

            Next time when you dream about good things, thank your Chrm1 and Chrm2 genes which facilitated the transfer from the non-dreamy state to the dream state where you can actually escape the reality. But, if you happen to encounter a nightmare, do not be mad at these genes, just thank them to alert you that your stress levels are high.

The importance of FOX1 Genes in the brain development 
Labeled diagram of neuron cells

We execute numerous numbers of functions every day. Some are voluntary like reading, exercising, writing or learning and involuntary like breathing, digesting or maintaining homeostasis or in other words maintaining the normal balance of the body.

            Long story short: we need our brains to breathe, eat, study, exercise and even dream! Our brains are comprised of trillion cells. The two types of brain cells-neurons and glial cells- are crucial for brain functioning. Neurons basically transmit the electrical signals throughout the body. The glial cells just provide insulation to these neurons to prevent damage to these precious brain cells which basically guide us to do everything we do every day. That is why glial cells are extremely important. But, still how does the body determine what cells become neurons and what becomes glial cells? Probably, this question motivated the scientists at SISSA to research about these brain cells and their origins.

            During research, scientists have discovered the importance of FOXg1 gene in the origins of the glial and neuron cell. As the prior knowledge tells us that when the FOX1 gene is mutated, there are abnormalities in the development of the structure of the brain giving rise to FOXG1 syndrome.  Previously it was suggested that the stem cells gave rise to the neurons and which in turn produce the glial cells through astrocytes. Astrocytes provide nutrients to the neurons and modulation of the neuron activity. However, what causes this process of transition was unknown. The SISSA researchers have now discovered the importance of FOXg1gene in the developmental processes.

            During the research, the scientists discovered that the level of FOXg1 gene expression reduces when the astrocyte production begins. Not only that, the FOXg1 “controls” the master genes and implies the choice between that of astrocytes and neurons.

            Now, why is this research important? This research is important because we now can better understand the role of FOXg1 genes in neurological disorders including the FOXg1 syndrome causes abnormal brain structure leading to intellectual disability. The FOXg1 gene plays an important role in brain development and perhaps if this function is compromised it is likely to create a cascade of problems.

However, with this research, the possibility of gene therapy is perceived to overcome the problem of the shortening time of the generation of the astroglial cells which is common in the abnormal brain development syndrome. Also, researching the importance of stem cells in developmental pathways can be useful to research more about the gene therapies to cure such abnormal brain developmental syndromes.

Promising Molecule Drug aimed to treat cancer

The common aim for the majority of the biological scientists is to tackle Cancer. Cancer is a growing complication due to lifestyle changes like long exposure to the UV light, disrupted sleep cycles, stress, and pollution. Many people experience stress caused by their workload. For personal or professional reasons it is a common tendency to compromise sleep which results in a disrupted circadian rhythm. In simple words, circadian rhythm means the normal sleep cycle of human beings. In research named”Circadian Rhythm Disruption in Cancer Biology” conducted by Christos Savvudis and Micheal Koutsilieris, it is cited from the International Agency for Research on (IARC) 2007 that, “shiftwork that involves circadian disruption [as] probably carcinogenic to humans”. Therefore, the disruption in circadian rhythm is linked to the development of cancer in humans.

            Nevertheless, the scientists at the University of Southern California have used the disrupted circadian rhythm as a tool to treat cancer. A disrupted body clock negatively affects the functioning of the normal cells. The same concept applies to the cancer cells. The researchers hypothesized that if the circadian clock of the cancer cells is disrupted it is possible to kill or at least hurt the cancer cells (“University”).

            The scientists at the University of Southern California discovered a molecule named GO289 which interacts with a protein which regulates the circadian rhythm of the cells. This interaction also disrupts the four other proteins that are essential for cell growth and survival. These proteins are used by the cancer cells to develop; however, disrupting this cycle can potentially cease the metastasis or spread of cancer. “The GO289 can jam the cogs of the cell’s circadian clock, slowing its cycles. And it can do so with little impact to healthy cells” (“University”).

            To test the efficiency of this new drug, “Go289” the researchers tested it on the human bone cells cancers. It was observed that the drug slowed the tumors; circadian clock. Additionally, it was tested on the human kidney cancer cells and the mice with acute myeloid leukemia. GO289 affected cancer cell metabolism and other circadian cycles that contributed to the growth of cancer.

The above photograph demonstrates the disrupted circadian rhythm of the human bone cancer cells caused by the drug molecule, GO289.

2018 Genetics Review

As we enter into the year 2019, we expect more scientific questions to be answered; we expect the humankind to progress by discovering unusual scientific phenomena and we expect to provide solutions to the problems through science. However, we all can gather new knowledge by developing from our previous knowledge. 2018 has been a year where new knowledge was available in the field of genetics. This blog is all about 2018 at a glance for genetics.
One such landmark event is the discovery of a human RNA which activates innate immunity when attacked by a virus. Research published in the Journal of Biological Chemistry reveals an RNA molecule which plays an important role in the defense against the virus. This RNA is known as the nc886. “Nc” means noncoding, therefore, this RNA never codes proteins. Nevertheless, it activates the chain of events that destroys viruses. This research can be important to study the human immune system.
Along with the research in the human immune system, a study issued in the journal Cell reported the role of viruses in shaping human evolution. Prior to this research, many believed that the ancestors of the human beings, Neanderthals, moved out of Africa to Eurasia and they adapted to the geographic area. However, this new study delineates a new possibility where the Neanderthals adapted mutations which were beneficial against the pathogens and these mutations were inherited by the humans. This research provides us with an insight that the genes inherit adaptations that are advantageous to us.
Moreover, the researchers at the Okinawa Institute of Science and Technology Graduate University have reported a specific transcription factor which changes gene expression, thus, playing a significant role in maintaining the immune system in the mice. The researchers discovered a factor also known as the JunB which stimulates the cells to activate the immunosuppressive function. This can provide us with an understanding of the development of autoimmune disease and cancer immunosuppression. Researcher, Koizumi, declared that this perception of these immune responses in various tissues can help in the treatment of a range of cancers and autoimmune-related diseases like rheumatoid arthritis.
With these researches in the year 2018, the researchers also discovered why Dunkin Donuts and Starbucks is in a profitable business. Because they studied a gene which is a reason behind why we like coffee so much. They found out that some people have inherited bitter taste genes. These genes stimulate a positive response from the brain causing them to drink more coffee. The scientists want to determine the health implications of this bitter taste genes.
Moreover, the biggest breakthrough news in genetics was the world’s first genetically edited babies in China. However, this is a controversial question. But it is significant as many people realized the importance of CRISPR technology. CRISPR/CAS9 is a gene found in the bacteria which is known for cutting the default gene. When bacterias are infected with a virus, they use this gene to “cut” the DNA of a harmful virus. This gene is used to delete the mutated1gene and add the donor gene. The mutated gene is cut by the “scissors” or CAS9 and the donor gene fills the void in the DNA.
The other research is my personal favorite as it is regarding the mitochondria: the energy bank of our body! In my biology class, I was taught that the mitochondria were inherited exclusively from our mothers. After this research done by the mitochondrial disease researcher at the Mayo Clinic at Jacksonville, FLA, it is revealed that the mitochondria are also passed by the fathers. Nevertheless, this claim is still being researched and we will soon understand the details. Isn’t it exciting???!!!
This year has been impressive as many kinds of research have presented us with new information. And it will be interesting to see how this research provides us with a new understanding of genes.

The world’s first genetically edited baby or in fact babies are born! Isn’t that surprising! But first, we need to know if this is true or fake. This blog summarizes the new controversy about the Chinese Professor, He Jiunki, who claims that he has successfully edited faulty genes in twins.
This all started on the 28th of November 2018 when Professor He at the Genome Summit in Hong Kong announced that he was successful in editing the genes of twin girls. The father of the twins was HIV positive whereas the mother was HIV negative. The twins were at the risk of inheriting HIV. However, Professor He with the use of the CRISPR/ CAS9 technology was able to reduce the twin’s risk of inheriting HIV. CRISPR/CAS9 is a gene found in the bacteria which is known for cutting the default gene. When bacteria are infected with a virus, they use this gene to “cut” the DNA of a harmful virus. This gene is used to delete the mutated1 gene and add the donor gene. The mutated gene is cut by the “scissors” or CAS9 and the donor gene fills the void in the DNA. This way the mutated gene is replaced by the donor gene. Nevertheless, all this is done while there exists a single human cell in other words, this is all performed on an embryo. As it is impossible to alter the DNAs in trillions of cells.  A pretty exciting and interesting technology right?
Many professors believe his research untrue because the University he worked did not fund the research, therefore, denying the validity of this claim. Also, many other scientists believe the information untrue as there is no scientific paper backing up his claims. Professor He asserts that he privately funded the research which involved the deleting of the gene of the twins, Lulu and Nana.
Moreover, the whole ethical questions come into the play. Are the genetic engineers playing Gods by going against nature?
Professor He played God and many ethicists believe that this action is unethical as Professor He has deliberately made one twin as a control which can make her susceptible to HIV whereas the other twin is not. CCR5 is a coreceptor protein which provides a way to infect other cells with the HIV virus. Professor He turned the CCR5 gene off in one twin and kept one gene on in the other twin. This action favors one twin over the other.
In conclusion, many ethicists and scientists reject this claim to be untrue. Please let me know your thoughts on the issue in the comment section below.

Mutations that caused evolution in the humans

The human body has evolved over the course of million years to perform highly complex mechanisms which are essential for its normal functioning in addition to complex mechanisms like thinking logically and the development of the language. These mechanisms include the development of the signaling in the nervous system which helps in responding to the stimuli, metabolism to provide energy for carrying out other functions in the body, understanding, and thinking, being able to communicate and even a simple task as holding something which is possible because of the development of the thumb. Ever thought how these developed?
It all starts with our good old friends- Primates.  Evidence for this theory can be the mitochondrial difference of 99% between the chimpanzee and the humans. The mitochondrion is the organelle in the cell which is responsible for the cellular respiration. It produces energy in the form of ATP (Adenosine Triphosphate). As the mitochondria contain their own DNA, they are used to identify how distantly or closely related the species are. Primates were basically arboreal which indicates that they lived on the trees.  The most significant evolution was Bipedalism. Bipedalism is a unique characteristic in the humans which allows them to walk on their two limbs. There have been many speculations about how the ancestors of humans developed bipedalism. This connects to the idea of Natural Selection that Charles Darwin presented in his famous work, Origin of Species. Darwin proposed that an offspring inherits the mutation from the parents. And as this mutation, becomes beneficial in a particular species it stays in the gene pool.  Maybe, a mutation was inherited and was beneficial; thus, remained in the gene pool.
Perhaps, the size of the human brain is a noteworthy evolution which gives us the ability to think and to communicate. We need to appreciate the human ability to do so many things many species cannot. Like the development of more than 100 languages and being able to reason and logically applying knowledge in our everyday lives. Extensive research indicates that genetic changes in the human genome were the main causality behind the brain size enlargement. Gene family which is suspected to be responsible for the brain enlargement is called the DUF1220 (Vallender). This is considered a novel gene. Novel genes are hypothesized to be the reason for the evolution in the human phenotype. The function of the DUF1220 is unknown; however, the researchers have discovered that it is expressed in the brain and the neurons. Another significant finding is that the amount of the gene being expressed increases in primates if they are closer to the human phenotype. Therefore, with larger brains, humans are capable of doing many things yet we sometimes find ourselves using it for the wrong means like cheating on a test! Just learn to appreciate the genes as they do so much for us, for example, they express many proteins so that we think and do good for our society!

Everything you need to know about stem cells

Recently, there have been a lot of speculations about stem cells and their ethicality. The main question is: “Is it ethical to kill an embryo in order to procure stem cells where that embryo has a potential to grow into a human being?” To answer this question we first need to understand what are stem cells? What benefits do they provide us with? What are some disadvantages associated? Can they be used to treat a person who has been diagnosed with a terminal illness like cancer or an organ failure?  
So let us begin with some basics. Stem cells are pluripotent cells, that is, they have an ability to develop into an organism. A zygote, product of a sperm and an ovum fusion, is a classic example of an undifferentiated stem cell. A zygote is a single undifferentiated cell which divides itself to form an embryo. The undifferentiated cells found in an embryo are called the Embryonic stem cells. As the embryo enters its eighth week it is called as a fetus. Here, the stem cells begin to form differentiated cells. These stem cells are called the fetal stem cells. Other types of stem cells are the Adult Stem Cells. These are a rare type of stem cells. Because as the human beings grow and mature, the cells in the body become specialized and lose their pluripotency. However, there are few stem cells found in the bone marrow of an adult. Blood stem cells are an example of adult stem cells.
Being said that, let us talk about how the stem cells are used as the regenerative medicine which is a breakthrough research to help cure terminal illnesses like leukemia, organ failure or are used for a joint replacement. Of the four types of stem cells, embryonic stem cells can be regarded as the most effective in developing into an organ or a tissue. The way it is done is by  “pre specializing”(“What”) the stem cells and inject it into the tissue or the organ where a transplant is needed. When the pre-specialized stem cells meet the growth chemicals they grow into a healthy organ or a tissue. It is an effective method which replaces a transplant. However, the risks of graft rejection still remain, as the developing organ is foreign to the body. Yet there are many advantages of stem cell therapy. They have an ability to cure the irreversible Alzheimer's disease, Parkinson’s disease, liver and kidney diseases. Not only transplants, stem cell research can also help the scientists to understand the patterns of human growth.
Nevertheless, with so many advantages there are many disadvantages of using the stem cells which question the ethicality of the stem cell research. Embryonic stem cells are used to study or to use for the most number of transplants. However, to do so the blastocyst is destroyed. Which means it kills an unborn life which could have grown into a human being. That is why many people believe that stem cells are unethical. Another disadvantage with stem cells is that adult stem cells are pre specialized that is they can just develop into specific organs. For example, brain stem cells can develop into brain cells they cannot develop into blood cells. And if the immune system cells are replaced by the stem cells they can identify the indigenous organs as “foreign” and can attack the organs leading to organ failure. Therefore, there are many risks involved in stem cells therapy.
Many people oppose stem cells and label the research “ unethical”. But, the technology is promising. With proper research, stem cells may have more advantages than disadvantages. Yet, the issue of ethicality remains. It is very unethical to kill an embryo for the research. However, I am very positive that the researchers will overcome this hurdle and ensure a breakthrough research which is ethical and helpful. But, as this happens we all need to be open-minded and form opinions after understanding the basics. I hope this blog helps you to understand what the stem cells are and their advantages or disadvantages and allows you to form opinions about this topic.
