Group led by Dr. Avinash Bajaj from Regional Centre for Biotechnology designed a low molecular weight hydrogel that can maintain sustained and sequential release of combination of drugs and inhibit the tumor progression in murine models. Using the bioconjugation strategies and biocompatible bile acid and peptide scaffolds, Dr. Bajaj’s group engineered a biocompatible and biodegradable […]

Group led by Dr. Avinash Bajaj synthesized twenty cholic acid-peptide conjugates and screened them for different gram-negative bacterial species. They showed that glycine-valine derived cholic acid amphiphile is effective and less haemolytic as compared to other amphiphiles. Various biophysical and biochemical assays validated the membrane-disrupting properties of the amphiphile. MD simulations deciphered that rigidity provided […]

Taste is a short-range contact chemosensation required by all animals to detect nutrient rich foods and avoid consuming toxic chemicals. In insects, it is also required to select mates and appropriate oviposition sites. Organization of the fruit fly Drosophila melanogaster taste system and availability of experimental tool box, makes Drosophila gustatory system an ideal model […]

Autophagy performs housekeeping functions for cells and maintains a functional mode by degrading damaged proteins and organelles and providing energy under starvation conditions. The process is tightly regulated by the evolutionarily conserved Atg genes, of which Atg5 is one such crucial mediator. Here, we have done a comprehensive quantitative proteome analysis of mouse embryonic fibroblasts that lack a functional […]

Methylation of genomic DNA can influence the transcription profile of an organism and may generate phenotypic diversity for rapid adaptation in a dynamic environment. M.HpyAXI is a type III DNA methyltransferase present in Helicobacter pylori and is upregulated at low pH. This enzyme may alter the expression of critical genes to ensure the survival of […]
