ONCOGENES AND HSP90 INHIBITORS

5366 | Aug 24 2012

PATHWAY OF HSP90 AND CANCER CELL LINES: Heat shock protein 90 or Hsp90 is actually a non-fibrous protein which gained its name from its molecular weight that is 90kDa. Hsp90 is most abundant cytoplasmic protein which plays a significant role in cells by acting like a molecular chaperone for many proteins related to some important signaling cascades of the cell. Different proteins chaperones that are existing in the cell, involve serine/theronine kinases and tyrosine kinases as well hence they are very much important for the proper regulation of cell growth and cell cycle. A detailed research is carried out to describe the relation between Hsp90 and cancers. To inhibit this chaperone i.e. Hsp90, the simple strategy of designing Hsp protein inhibitor was developed when Hsp90 was found to be existing in different cancerous cell lines activated through the activation of oncogenes. It has been proved a very fruitful therapy for cancer. [Read the Full Post]

HSP INHIBITORS AGAINST PROTEIN FOLDING

4578 | Mar 19 2012

Introduction: Cellular Quality Assurance The network of chemical reactions linked to the mechanisms behind cellular growth, proliferation and differentiation are complex. Referred to as biochemical pathways these mechanisms operate on some simple principles starting with the receipt of a message from the host system to the cell itself. The pathway system can be likened to a production line facility with the product being a normal health cell. So mechanisms exists for stock piling of raw materials, for the synthesis of component parts, for the recycling of waste materials, for the removal of unwelcome molecules, quality assurance and final product viability. One the key aspects of cellular growth is the delicacy of the whole process, it does not take much to drive a mechanism off balance and produce a faulty product, to ensure quality under stress induced conditions a series of proteins exist referred to as Heat Shock Proteins that assess the quality of proteins being constructed for cell growth purposes.

JNK, a potential therapeutic target for the treatment of nephrotoxicity

3963 | Nov 14 2011

Nephrotoxicity is a poisonous effect of some substances, including toxic chemicals and medication, on the kidneys, and cyclosporine (CsA) nephrotoxicity is one kind of nephrotoxicity. It is reported that the epithelial to mesenchymal transition(EMT) is an important mechanism contributing to the pathogenesis of cyclosporine (CsA) nephrotoxicity by promoting the generation of myofibroblasts. Some studies suggested that he endoplasmic reticulum (ER) stress as a potential mechanism may participate in the modulation of tubular cell plasticity in CsA-induced EPCs[1]. However, the precise mechanisms have not been known. [Read the Full Post]

Roles of Hsp90 in wound healing and cancer

5962 | Oct 24 2011

Wound healing is an intricate process in which the skin (or another organ-tissue) repairs itself after injury. At present, local growth factors are considered to be the driving force for wound healing and only recombinant human platelet-derived growth factor-BB (PDGF-BB) has been approved by US FDA for topical treatment of diabetic ulcers. However, the use of PDGF-BB in clinical trials has been limited for its modest efficacy, high cost and risk of causing cancer. Thus, novel treatment for wound healing is needed to be explored.
