Multifunctional transcriptional factor; ICR;Cg-Hsf1<tm1Anak> (RBRC10003)
Courtesy of Akira Nakai, M.D., Ph.D. HSF1 plays important roles in diverse pathophysiological processes. For example, HSF1 deficiency is associated with enhanced inclusion formation of polyglutamine protein in the brain, abnormal nasal cavity, exacerbated febrile response (upper), abnormal circadian rhythm, inhibited tumorigenesis, and increased aggression (lower). |

Under conditions of heat or other stresses, heat shock response is induced to maintain protein homeostasis inside cells. In this pathway, HSF1 (heat shock transcription factor 1) plays a pivotal role in robust induction of heat shock proteins, which facilitate protein folding as molecular chaperones. HSF1 is known to be evolutionarily conserved from yeast to humans. Furthermore, it is noteworthy that HSF1 works in a wide variety of physiological phenomena such as development, metabolism, aging, age-related neurodegenerative disease, cancer and so on, irrespective of stress exposure. Indeed, analysis of Hsf1 gene knockout mice (RBRC10003) [1] revealed that HSF1 is involved in not only some physiological processes (olfactory neurogenesis [2], steroidogenesis [3], muscle hypertrophy [4], etc.) but also some disease onset and pathology (central nervous system disease [5-9], digestive system disease [10, 11], etc.). Therefore, Hsf1 gene knockout mice will be useful for exploration of a novel therapeutic target for HSF1-related disease. |
