The nuclear transcription factor FoxG1 affects the sensitivity of mimetic aging hair cells to inflammation by regulating autophagy pathways
In this study, we first found that FoxG1 expression and autophagy both increased gradually in the low concentration lipopolysaccharide (LPS)-induced inflammation model, while after high concentration of LPS treatment both FoxG1 expression and autophagy levels decreased as the concentration of LPS increased. We then used siRNA to downregulate Foxg1 expression in hair cell-like OC-1 cells and found that cell death and apoptosis were significantly increased after LPS injury. Furthermore, we used d-galactose (D-gal) to create an aging model with hair cell-like OC-1 cells and cochlear explant cultures in vitro and found tha...

A stress response p38 MAP kinase inhibitor SB202190 promoted TFEB/TFE3-dependent autophagy and lysosomal biogenesis independent of p38
Publication date: Available online 28 January 2020Source: Redox BiologyAuthor(s): Chuanbin Yang, Zhou Zhu, Benjamin Chun-Kit Tong, Ashok Iyaswamy, Wen-Jian Xie, Yu Zhu, Sravan Gopalkrishnashetty Sreenivasmurthy, Krishnamoorthi Senthilkumar, King-Ho Cheung, Ju-Xian Song, Hong-Jie Zhang, Min LiAbstractTFEB (transcription factor EB) and TFE3 (transcription factor E3) are “master regulators” of autophagy and lysosomal biogenesis. The stress response p38 mitogen-activated protein (MAP) kinases affects multiple intracellular responses including inflammation, cell growth, differentiation, cell death, senescence, tumorigenesis...
