Interview of Ms. Sarika Saxena

by Paras Chopra

For the second edition of Jeev, I interviewed Ms. Sarika Saxena, who is presently teaching us at our college as a guest faculty and doing research in the field of structural biology. Below is the interview:

1. Brief Biography
I am a simple, down to earth person. Whatever I achieved in my life is the outcome of my hard work, dedication and my sincerity towards my work. I completed my graduation from Delhi-University, post-graduation in Biochemistry from Jamia-Hamdard and then entered into research field and completed my doctorate in Biochemistry from Delhi University. I qualified All- India level comepetitive exam of NET (National eligibility Test) conducted by CSIR-UGC.I qualified another exam of Net (in Plant Biochemistry) conducted by ASRB (Agricultural scientist research board). During my doctorate I got S.R.F. (Senior research fellowship) from Lady Tata Memorial Trust, Mumbai. After completing my doctorate I joined IGIB (Institute of Genomics And Integrative Biology, A CSIR Research Institute) and worked there on functional genomics (i.e. to identify the mutations) in projects related with drug response in Asthmatic/schizophrenic patients. I’ve lot of interest in research field and implementing my own ideas so decided to move in academics and in free time to start my research career on my own projects. So, I joined DCE (Editors' note: our college, Delhi College of Engineering). and going to complete one year at the same place.

2. In what field are you currently doing research?
My current field of research: is functional genomics and structural biology (oligonucleotide therapeutics).

3. How did you get inspired to work in this field?
My inspiration is due to my interest in the concept of oligonucleotide therapeutics. There are so many incurable diseases like cancer, AIDS, leukemia and so on and to treat these diseases no ready drug is available with us. In such situations, certainly the patients life becomes miserable. In curing these diseases the concept of oligonucleotide therapeutics provides the best hopes, though limitations are there but work is in progress actively in the same field.

4. What exact research are you doing?
I did the work on antigene strategy (i.e. Triplex formation) and applied the same to block the gene target of one of the protooncogene (i.e. cancer causing gene). My aim was to use the synthetic oligonucleotide stretch as a drug so that it can bind to the target DNA duplex of protooncogene. Target was located near 3’-UTR region (i.e. regulatory region) and the basic idea was to form a fairly stable triplex so that it can inhibit the poly-A tail formation. This is because the all the proteins and accessory factors required for poly-A tail formation are specific for duplex not for the triplex one so it’ll inhibit the poly-A tail formation and in the absence of Poly-A tail formation, mRNA will destabilize and no oncoprotein formation will be there and hence it can prevent the cancer. This strategy can be used to block any biologically significant process like transcription, replication, recombination of any gene depending upon the target availability. I studied all possible structural changes in different conditions of the target duplex by using CD (circular dichorism), stability by UV-thermal melting and qualitatively by Gel electrophoresis. First time, I observed the different competitive structural existence within the target duplex itself, going to publish very soon. I learnt the peptide designing and did the synthesis on my own and first time design the series of peptides that can selectively recognize the specific structure (i.e. G-quadruplex) and destabilize it. Apart from that I’m doing the work on functional genomics (i.e. mutation detection) and then to relate these mutations with structural changes within biologically relevant gene target.

5. What do you think is future of life sciences?
Future of life science: is certainly very bright. Life science is the only field that opens the fields for active research. Basically life science includes all the fields like Biochemistry, Biotechnology, Molecular Biology, Microbiology, Bioinformatics, Environmental biology, toxicology. Knowledge in all these fields can only give the idea related with any disease and to find ways to eradicate them. In today’s time we all living in very competitive and tense life and it’ll not be wrong to say that disease progress rate is much faster than cure. In such situations life-science is the only hope for all of us.

6. Any advice for students?
Always believe in selecting and moving the right direction for your career depending upon on interest. Always keep an eye on your target and do maximum efforts whatever you can with positive attitude, your hard-work and sincerity. Nothing is impossible and always remembers ‘THE MAN WHO WINS IS THE MAN WHO THINK HE CAN’. So, believe in yourself and move ahead always with full confidence.

7. Are there any Job/Research opportunities in your company/institute?
One can apply for basic training if you’re fresher. After completing your masters and qualifying NET (Editors' note: National Eligibility Test) one can apply for research (Ph.D.) also. If interested in doing job, one can join as project trainee/ project assistant in any ongoing research project.

8. What are your plans for the future?
Research is my main aim. I never believe in rushing towards anything blindly always prefers to be different and to perform something satisfactory. So, planning to move in my research field actively, so I’ll apply for post-doctoral fellowship in future. Presently, my preference will be to enter in academics and side by side in free time to start the work on my own projects.

9. How can society contribute to the development of life sciences?
Society can certainly contribute by increasing their awareness about themselves like they should have the basic idea about their health and about biological processes in human body so that they can understand and differentiate themselves about the advantages/disadvantages of selecting their diets, importance of balanced diet, importance of routines to feel fit and fine, selecting their life-style and to understand the concept about the new developments in all the main fields of science.

10. What should future research be directed at, according to you?
In every field of life-sciences all over the world the research is going on very actively in every field. Main aim of all the fields is to find the ways to cure incurable diseases (i.e. drug targets), to synthesize new compounds that must have biological activity, to clone the important genes may linked with any disease or with regulation of some biologically significant process. Understanding the basic concepts of gene regulations, identify the mutations, structural studies to identify the changes in conformations within DNA/Proteins and to identify the targets for selective ligand binding. Knowledge in genome application mainly is opening the new fields for selecting the best candidate genes that may be linked in any developmental pathway of any disease and to find out the molecular markers. Bioinformatics mainly play important role in managing all the data and playing the major role in genome applications. Using bioinformatics only it could have been possible to sequence the genome and in microarray, it plays very important role in compiling and analyzing the data of genomes. In agricultural fields, scientists are doing the work on increasing the productions within short time and to generate new and best varieties by cloning the selective genes and so on.
