HSF1 and amyloidosis: The levels of mRNA for the common molecular chaperones heat shock protein family A (HSP70) Member 1B (Hspa1b) and crystallin alpha B (Cryab), which are primarily regulated by the transcription factor heat shock factor 1 (HSF1) (Benarroch, 2011; Kourtis and Tavernarakis et al., 2011), showed no change in response to either IT or amyloidosis in the liver (Fig. S6C).
