Cancer is a devastating disease that has affected millions of people, consumed tremendous efforts in the treatment/care and is incurable. Statistics from www.seer.cancer.gov show 14,140,254 people were living with cancer in 2013 in US with 1,685,210 new cases projected and 595,690 estimated deaths to occur due to cancer in 2016. Number of people surviving cancer (measured as 5-year survival rat...

PURPOSE Accumulation and precipitation of abnormal proteins are associated with many age-related diseases. The ubiquitin-proteasome pathway (UPP) is one of the protein quality control mechanisms that selectively degrade damaged or obsolete proteins. The other arm of the protein quality control mechanism is molecular chaperones, which bind to and help refold unfolded or misfolded proteins. We pr...

Heat shock protein 90 (Hsp90) is a molecular chaperone that assists folding in an Adenosine triphosphate (ATP)-dependent way. Hsp90 has been reported to interact with Alzheimeŕs disease associated amyloid-β (Aβ) peptides and suppress toxic oligomer- fibril formation. However, the mechanism remains largely unclear. Here we use combination of atomic force microscopy (AFM) imaging, circular dichro...
