摘要

Objective: To investigate the effects of heat shock transcription factor 1(HSF1) gene on the conslitutively expressed αB-Crystallin (αBC) in mice myocardium. Methods: The expression levels of constitutive αBC in HSF1 knockout (hsf1 -/- ) and HSF1 wild type (hsf1 +/+) mice myocardium were evaluated by western blot and immunohistochemistry. Results: The αBC levels in hsf1 -/- and hsf1 +/+ were 68. 42 +- 4. 16, 100. 00 +- 7. 58, respectively (P<0. 05, cytoso-lic fraction), and 20. 53 +- 1. 01, 37. 55 +- 1. 91, respectively (P<0. 05, pellet fraction). The αBC signals decreased significantly in hsf1 -/- myocardium when compared with those in hsf1 +/+ myocardium stained with fluorescence immunohistochemistry. Conclusion: HSF1 is an important, but not the only factor, which mediates the Constitutively expressed αBC.
