Objectives: Dysregulation of proteolysis underlies diseases like cancer. Protease inhibitors (PIs) regulate many biological functions and hence have potential anticancer properties. With this background, the current study aimed to identify the PI from natural sources such as plants and microbes against trypsin (a protease), which was assayed against casein, using an ultraviolet spectrophotometer-based methodology.

OR3 induced apoptosis and inhibited HepG2 cell proliferation, confirmed by caspase activation, Sub-G1 phase cell cycle arrest, and reduced colony formation. Proteomic analysis revealed altered expression of proteins associated with ribosomal function, mRNA processing, nuclear transport, proteasome activity, carbohydrate metabolism, chaperone function, histone regulation, and vesicle-mediated transport.

Methionine deprivation using L-methioninase along with chemotherapy appears promising towards cancer management. The present study is an attempt to use a new combination of L-methioninase with Tamoxifen (TAM) to treat breast cancer in mice.

Hence, in the present study, anticancer potential of a yellow pigment fraction, OR3, isolated from Streptomyces coelicolor JUACT03 was assessed on the breast cancer cell line MCF-7. TLC-fractionated OR3 pigment was subjected to HPLC and GC-MS analysis for characterization and identification of the bioactive component.

With respect to this, the present study evaluates the in vitro apoptogenic profile of secondary metabolites from the lichen towards cancer cell lines. Treatment with TLC-purified fraction 1 from resulted in significant reduction in the cell viabilities of cancer cells with IC values ranging between 1.

Using industrial by-products as PHA feedstocks could improve its process economics and market implementation. Valorizing the plenteous, nutritive pollutant whey as PHA production feedstock would be an excellent whey management strategy.

The members of the genus are one of the important sources of bioactive compounds. In the present study, , isolated from a garden soil in Madurai district of Tamil Nadu, was found to produce a highly promising anti-cancer metabolite.
