Research paves way for better drugs for breast cancer

New Delhi, Aug 23: In a study that could help design better drugs for breast cancer, researchers at the Indian Institute of Science Education and Research (IISER)-Bhopal have identified the mechanism by which breast cancer cells proliferate and spread.  The team studied the regulation of a gene called ‘ESRP1’ in breast cancer. They found that there is a difference in the expression of the ESRP1 gene between normal and tumour tissues of breast cancer patients. The gene was expressed more in breast tumour tissues than normal tissues. They then explored the regulatory mechanism behind this. The expression of a gene…

Indian scientists develop artificial enzyme to keep HIV virus in check

New Delhi: People suffering from Human Immunodeficiency Virus (HIV) infection can now hope to have a better quality of life with researchers at the Bengaluru-based Indian Institute of Science (IISc) developing a nano alternative to a natural enzyme that is used to block reactivation and replication of the virus in the host’s immune cells. Made from vanadium pentoxide nanosheets, the new “nanozymes” work by mimicking the natural enzyme called glutathione peroxidase to help reduce oxidative stress levels in the host’s cells, which is required to keep the virus in check. Presently, there is no method available to completely eliminate HIV…
