Mahak Sharma research pathways inside human cells to search out genetic issues


Communication is essential for a workforce to realize success, and that holds true not only for people however for cells within the human physique too, which need to work collectively to carry out essential capabilities needed for survival. Inside a cell as properly, there are compartments that want to speak with one another and transport mobile cargo reminiscent of proteins to their right places.

An essential a part of what Mahak Sharma, 36, affiliate professor within the division of organic sciences on the Indian Institute of Science Schooling and Analysis (IISER), Mohali, does is examine how mobile pathways instrumental in sending proteins to focused subcellular places are regulated. Analyzing the gamers regulating these pathways helps her pinpoint the perform of proteins, mutation through which can result in issues reminiscent of lysosomal storage ailments characterised by an irregular build-up of assorted poisonous supplies within the physique’s cells.


A recipient of the Division of Biotechnology Nationwide Ladies Bio-scientist Award in 2018 together with the Nationwide Academy of Sciences (NASI), India, and the Indian Nationwide Science Academy (INSA) awards, Sharma’s work on the perform of a lysosomal protein PLEKHM1 (mutation in which results in osteopetrosis or “stone bone” the place bone resorption is defective) was printed within the Journal of Cell Biology in 2017. The work was executed in collaboration along with her husband, the laboratory of Dr Amit Tuli at CSIR-IMTECH (Chandigarh). The examine garnered vital consideration from the cell biology neighborhood and was additionally chosen as the highest ten papers of 2017 by the journal.

Sharma’s examine centered on the mechanisms that regulates PLEKHM1’s affiliation with lysosomes, that are sacs of enzymes inside cells that digest giant molecules and move the digested materials on to different components of the cell for recycling; and the way its perform is regulated throughout endocytosis (when a dwelling cell takes in matter) and autophagy (cell mechanism breaking apart broken subcellular buildings). Sharma, who did her put up doctoral diploma on the division of rheumatology, immunology and allergy in Harvard Medical College with Prof Michael Brenner , an immunologist and a PhD from College of Nebraska Medical Centre, Omaha, USA, says her analysis will assist to higher perceive the elemental means of how proteins throughout the cell are transported to lysosomes for degradation and recycling. Her laboratory has additionally been concerned in understanding how micro organism reminiscent of Salmonella (that causes gastroenteritis, usually referred to meals poisoning) exploits these intracellular communication pathways throughout the human cell for its personal development and survival.


Born and introduced up in Delhi by her surgeon father and gynecologist mom, Sharma had a pure inclination for science, an curiosity that grew when she and her older sister had been allowed right into a lab at residence on and tinkered with the microscope.

A B.Tech in biotechnology from Guru Gobind Singh Indraprastha College, Delhi, Sharma joined IISER Mohali in 2011 after coming back from the USA. After doing her analysis coaching in USA, becoming a member of IISER Mohali, which didn’t have its personal campus on the time, was a giant change. When she joined the institute she needed to design her analysis lab from scratch, one thing “that I had no expertise of,” she says. Funding, grants – every part takes time, she says, and “entails a number of paperwork”. Regardless that the scenario has improved over time, issues have to hurry up. “Scientists can’t give the identical outcomes as proposed when you drastically reduce their price range and don’t launch funds on time” she says.

Sharma, who has a two-month-old daughter, now, expects her on a regular basis schedule, involving writing of journals, paperwork, taking courses and lab work, to vary within the coming months. The nice factor is, IISER Mohali has a day care centre and adaptability of timing, which, she says, is essential for scientists who need to steadiness household and work.

When not working, she loves binge watching tv exhibits on Netflix; and sometimes takes breaks to spend time “near nature”.

She’s impressed by her PhD mentors Steve Caplan, principal investigator and professor of biochemistry and molecular biology on the College of Nebraska Medical Centre and Naava Naslavasky, assistant professor in the identical division.
