Construction of heat shock protein 90α expressing plasmid and the effect of the protein on tumor growth in vivo

Heat shock protein 90 (Hsp90) is a major heatshock protein whose functions are necessary for livingorganisms, including both procaryotes and eucaryotes.Human Hsp90 consists of two forms, Hsp90α andHsp90β. Expression of Hsp90α appears to be inducible bydifferent stimuli. Adenovirus EIA gene products andtransformation with the H-ras oncogene can induce aselective overexpression of Hsp90α. Hsp90α was found
