What is life? It was this initial curiosity that led me into the magnetic world of biology. During my final year of higher secondary school, I came across the plant hybridization experiments of Gregor Johann Mendel, a famous botanist and the father of modern genetics. His work fostered my scientific temper and led me to pursue a Bachelor’s degree in Botany. However, during my undergraduate years I discovered that that the theoretical knowledge that I was gaining was at the organism level, and I wanted to delve deeper into understanding what was happening at the molecular level. This led me to pursue a Master’s degree in Biophysics and Molecular Biology. It is my unchanging aspiration to explore and to discover the mysteries of the inner workings …show more content…

Fourth and most importantly, there are several professors affiliated with the GSBS program whose thrust areas of research align well with my scientific …show more content…
George A Calin’s laboratory. Two of the group's research projects in which I am highly motivated to work are the Identification of microRNA as a diagnostic marker in human cancers and Development of new therapeutic strategies involving microRNAs. Prof. Calin’s pioneered the idea that microRNA genes are involved in human tumorigenesis (Calin et al., PNAS, 2002) and his group also proved that another family of ncRNAs named ultraconserved genes (UCGs) are involved in human cancers and directly interact with miRNAs (Calin et al., Cancer Cell, 2007). Also, the idea that microRNAs could function as hormones is truly fascinating (Cortez et al., Nature Reviews, 2011). My motivation to work with Prof. Calin led to me contacting him via Email and Skype, and I was thrilled to get an encouraging reply. In addition to the role of non-coding RNA in cancer, I am also intrigued by Dr. Xiongbin Lu's research work on investigating the roles of microRNAs and other non-coding RNAs in the DNA damage response. These labs and many others would be a good fit for my background and research

In my first project, I modeled a rare form of non-dimerizing Ros1 fusion by genome editing which leads to gliomas in mice. Surprisingly, only homozygous deletion at 6q locus leading to Gopc-Ros1 fusion leads to tumor formation in vivo (Kannan et al, in preparation). This study demonstrates that apart from the resulting oncogenic fusion, genes lost as a result of deletion could play an essential function in tumorigensis and highlights the power of genome editing. To build my training on cancer research, I applied and obtained the Translational Research Oncology Training fellowship offered my Memorial Sloan Kettering Cancer Center. TROT has built a solid foundation to my cancer research.
As a laboratory prep, I was able to set up labs for freshmen and sophomore biology classes. Also, I made visits to my professor’s labs to observe the procedures graduate students used for their experiments and I loved it. After completion of my freshman year, I participated in the “Maternal Child Health Pipeline Training Program” that following summer. I conducted field research that focused on the public health of mothers and children in rural communities. The fall semester of sophomore year, I shadowed graduate students studying breast cancer cells. Later that same year, I began my own research with laser-induced breakdown spectroscopy (LIBS). Upon my junior year, I was accepted into the Virginia College of Osteopathic Medical Program in Auburn, Alabama. At the same time, I was accepted into the Tropical and Infectious Diseases Association in Iquitos, Peru. I was able to study abroad and work in a lab focusing on the negative gram bacteria that was in the water of the poor community of Iquitos, Peru. All of the opportunities I was able to be a part of from my freshman year till this present day has reconfirmed my passion and contributed to my specific area of research and the population I want to
I really love science, especially biology. Growing up I have always been fascinated with the question of how something as complicated as a human being could come about. Later, after learning about many of our biological functions, biology only began to seem more incredible. It is astonishing that the intricate functions in living creatures all fit together and operate together so smoothly. Amongst these different biological systems, I have always found the communication systems such as the nervous and endocrine system really interesting, in particular the brain. Consciousness is one of the few things science cannot explain yet, but biology can
Cancer is still a major threat to humanity. Every year it causes a large number of deaths. Breast cancer and cervical cancer are a leading cause of death in women in the western countries. Drugs prescribed for both of them are now being challenged. So if we could understand the genetics of both these cancers and understand the pattern of inheritance of the mutated allele’s one could prevent these cancers (especially breast cancer) before its onset. Understanding the functions of lncRNA is important for knowing and treating cervical cancer. Also, finding out the faulty genes in both the types of cancers could be helpful for knowing the genetic pathway. Taking all this together, cancer genetics is an important and will be a necessary tool in the future for treating and curing all types of cancers.
The human body is a remarkable and intricate machine with a complexity that is still beyond our understanding. From the DNA, to cells and proteins, there is a vast world we do not yet comprehend. And that is what I find most exciting: looking for the answers hidden inside us at every beating of our hearts. The fact that we can use the knowledge we acquire from unveiling the secrets of the human body and apply it to medicine to diagnose and treat diseases, has been my main reason for wanting to become a Biomedical scientist.
An important aspect of my overarching goal for college is to garner an abundance of real world experiences. Through the opportunities provided by the Honors College, I know that I will not have any trouble doing so. Having previously worked with metabolic diseases and cancer, I hope to continue my research in these fields by using the opportunities at this premier research university. Through the VCU Medical Center and programs like UROP, I desire to collaborate with professors and faculty members to discover more about human diseases. A particular program at the Honors College that interests me is the Freshman Research
Thus with the help of a systematic computational protocol of analysis and filtering we were able to isolate certain genes that can considerably alter correct genetic functioning due to predicted mutations in their nucleotide sequences. Given the functions of the above described genes, it can be said that their under or overexpression is crucial to the manifestation of cancer. The analysis of microRNA Target Site SNPs corroborating these facts say that they also might have a determining role to play in the cause of disease.
A USC researcher is interested in the roles of coregulators in steroid hormone regulation of transcription in cancer cells and would like to write a grant proposal on this topic. The two key coregulators of interests are Hic-5 and G9a. As he is preparing the proposal, he hopes to find information about the following questions:
Many people believed that criminal behavior of a person comes from the genes passed down. In recent years, tests have shown that genes and criminal behavior have little to or no correlation. Certain genetic factors may create a predisposition for a particular illness, but that probability depends on the environment a person was reared in. The social relationships that a person forms with the people in their environment and the external components of that environment is what can shape their criminal behavior. Criminal behavior can not be biologically determined because a person who carries a gene for a particular mental illness needs certain elements to develop that illness, like the type of social relationships a person develops with people
Growing up I’ve always been fascinated with animals from the neighbor’s cat to the huge elephants at the zoo. Although there were other activities I was passionate about such as singing and performing, at the time I felt learning and caring about animals would be most fulfilling. As I progressed in my schooling I realized how much I enjoyed and naturally excelled in science. I was successful in completing a 4-year comprehensive and rigorous curriculum of veterinary and biomedical sciences undergraduate program at the Penn State University. This environment provided me with access to all aspects of science equipment, lab animals, and networking resources.
Former studies have demonstrated that lncRNA are capable of influencing different cellular process like proliferation, cell cycle progression, cell growth and apoptosis (Han et al, 2013) and also involves post transcriptional gene regulation through controlling process like transport, splicing, transcriptional gene silencing through regulating chromatin structure, epigenetic gene expression, cell structure integrity etc. Because of their roles in the regulation of multiple molecular pathways, we can assure that, the long non coding RNA and its altered expression playing an important role in cancer etiology. For example, the lncRNA PCAT-1 (prostate cancer-associated ncRNA transcript 1) is over expressed in prostate cancer (Han et al., 2013) and expression levels of HOTAIR (HOX transcript antisense RNA), MALAT1 (metastasis associated lung adenocarcinoma transcript 1) are found to be up-regulated in colorectal, lung, breast, gastric, and bladder cancers. And some have seen as down-regulated like such as MEG3 (maternally expressed gene 3), lincRNA-p21, GAS-5 (growth arrest specific transcript
For Fall 2017, I will be attending UCLA pursuing a Bachelor of Science in Biochemistry, planning to apply for medical school after. I have always been intrigued about the wonders of life and the mechanism behind each process that we observe. There has been no doubt in my mind that I want to pursue a career in the chemistry field since I have decided to commit my education in the study of matter. My curiosity for the subject expands from my academics into my daily life when I begin to wonder about the phenomena behind my observations of natural and mechanical processes. My favorite activity in my chemistry class and Science Club is lab work.
I know that my opportunities for growth are amplified when I have access to the most challenging material and when I am surrounded by the most productive people. Having worked in Microbiology Lab and conducting research in Biochemistry Lab, I have built the most solid credentials available to benefit from the undergraduate research programs. I am eager to explore new skills to help to discover ways to treat and cure diseases. I would be thrilled to spend a summer working side-by-side with some of the most talented scientists in the world in an environment devoted exclusively to biomedical research. I would love the opportunity to learn the latest innovative research, tools, techniques, and applications used by leading scientific institutes
I have always been intrigued by the field of science and that is the reason I pursued the field of Biochemistry for my undergraduate studies. How The Human body works and the different determinants that can affect one's health or a community as a whole have always been captivating to me. I wanted to emerge in a profession that is beneficial for me, my community, and the world I live in. I came to realize through various science courses and health care experiences that a career in health care was the best path for me to outreach my community and the world.
