| Outline of Final Research Achievements |
In lung fibroblast CCD33Lu cells, simultaneous stimulation of TGF-beta1 and SRT1720 did not enhance the expression of HSP47 in comparison with single stimulation of TGF-beta1.However, pre-incubation of SRT1720 two hours before enhanced the expression of HSP47 mRNA. Immunohistochemistry could not show the significant difference of the expression of HSP47 in murine bleomycin-induced pulmonary fibrosis between SRT1720 treated group and untreated group. Although SRT1720 enhanced the expression of HSP47 mRNA, HSP47 did not increase in protein levels. We could not conclude that SRT1720 increased the pulmonary fibrosis via HSP47 expression.
