    INTRODUCTION A major obstacle in the successful treatment of cancer is the development of resistance mechanisms to drug treatment. Various cellular changes that have been implicated in the development of drug resistance in cancer cells include: the increased expressions of P-glycoprotein (a multidrug transport protein) and multidrug resistance-associated protein (MRP-1); increased levels of the cellular detoxification protein‚ glutathione; and changes in the expression of apoptosis associated

    incubated for 48 h and subjected to agarose gel electrophoresis. DNA ladder characteristic of apoptosis were observed in both cell lines (Fig. 5). No DNA fragmentation occurred in the untreated cells. 3.9. Caspase-3 expression in apoptotic cells The molecular effectors that activate a series of protease that leads to programmed cell death by intrinsic and extrinsic pathways are known as caspases. Caspase-3 dependent apoptotic cell death was induced by Pierisin-6 in human cancer cell lines were . The HeLa

    or Maxam/Gilberts sequencing. Introduction The capacity to segregate and amplify individual genes from an intricate genome using recombinant DNA technology technique like PCR has profoundly influenced ways scientists explored the obscurities in biology. Some of the major accomplishments of Recombinant DNA technology include the synthesis of medically essential proteins like insulin and developing new vaccines routes (Kingsman and Kingsman‚ 1988; Primrose et al.‚ 2001). Gene Cloning allows the
