چکیده انگلیسی
Heat shock transcription factor 1 (HSF1) regulates heat shock proteins (HSPs), which assist in protein folding and inhibit protein denaturation following stress. HSF1 was firstly cloned from orange-spotted grouper and exists as two isoforms, one with (osgHSF1a) and one without (osgHSF1b) exon 11. Heat exposure increased the expression of osgHSF1b while cold exposure increased that of osgHSF1a. Both isoforms were mainly expressed in the brains, eyes, and fins. Expression of osgHSF1b was higher than osgHSF1a during development. Poly I:C and LPS could also induce osgHSF1 isoforms expression differentially. Exposure to nervous necrosis virus (NNV) increased the level of both osgHSF1 isoforms at 12Â h. GF-1 cells with overexpression of osgHSF1 isoforms enhanced viral loads within 24Â h, whereas both pharmacological inhibition and RNA interference of HSF1 reduced virus infection. This study shows that osgHSF1 can support the early stage of virus infection and provides a new insight into the molecular regulation of osgHSF1 between the influence of temperatures and immunity.
