Protein aggregation studies: Aggregation studies currently underway are involving human serum albumin, lysozyme and the amyloid peptide fragment Ab25-35. Effects of a static electric field on the disruption of fibrils have been reported. Work with polyphenols and surfactants on the fibrillation of proteins have been initiated in order to study the amyloid fibrils, the hallmark of neurodegenerative diseases.
Studies with the eye lens proteins: Modified γ-crystallin (HGCc) from the discarded cataractous emulsion of patients was isolated and characterized. Studies showed that the major polyphenol present in green tea, EGCG was able to prevent tryptophan oxidation of cataractous ocular lens human γ-crystallin in presence of H2O2. The discarded mass is being used to prepare protein nanoparticles and films for applications in drug delivery, wound healing etc.
Protein ligand binding: Studies with ribonucleases such as angiogenin, indicated that the process of angiogenesis, the capacity to form blood vessels, was inhibited by polyphenols present in green tea. The polyphenols behave as noncompetitive inhibitors of Ribonuclease A. Other inhibitors of the proteins are being developed in addition to an investigation into the effects of oxidative stress on the protein.
