Brief Profile:

She has obtained her Masters degree in Biochemistry from the University of Hyderabad and has a Ph.D in Biochemistry from Osmania University, Hyderabad. Dr. Ismail joined the NIN in 2008 and the focus of her research is on non-classical functions of vitamin D. Vitamin D is now known to play an important role in many tissues/organs not involved in calcium homeostasis. Newer functions of this vitamin are being unraveled each year. In recent years, vitamin D deficiency has been reported to be rampant worldwide. Currently, her group is trying to understand the biochemical and molecular mechanism(s) that play a role during vitamin D deficiency in muscle and adipose tissue function. Her studies revealed that vitamin D deficiency induced muscle wasting occurs through the ubiquitin proteasome pathway. Dr. Ismail’s research indicates that both vitamin D and calcium are critical in the maintenance of normal muscle and adipose function.

Another area of her interest is the role of nutraceuticals as anticancer agents. Dietary ingredients contain phytochemicals or natural agents a.k.a ‘nutraceuticals’, which act thru multiple molecular targets and help in the prevention or treatment of cancer. Currently, work is in progress to decipher the potential anticancer role of few dietary ingredients in breast and prostate cancer models.

Dr. Ismail received post-doctoral training in the field of vitamin D at the MD Anderson Cancer Center, TX, and in the area of steroid receptors at the University of Miami, FL, USA; and is a recipient of the Young Investigator Award at the ASBMR, USA. She was awarded the Ramanujan Fellowship and Young Scientist Project from the Department of Science & Technology, India. She also received International Travel Grant from DST & ICMR. The research work in her lab is funded by DBT, DST and intramural grants from ICMR. She is a Life member of both the Nutrition Society of India (NSI) and Society of Biological Chemists India (SBC-I). She is a research supervisor in Biochemistry at Osmania University, Hyderabad, India.
