Autophagy Activation by Transcription Factor EB (TFEB) in Striatum of HDQ175/Q7 Mice
BACKGROUND Mutant huntingtin (mHTT) is encoded by the Huntington's disease (HD) gene and its accumulation in the brain contributes to HD pathogenesis. Reducing mHTT levels through activation of the autophagosome-lysosomal pathway may have therapeutic benefit. Transcription factor EB (TFEB) regulates lysosome biogenesis and autophagy. OBJECTIVE To examine if increasing TFEB protein levels in H...
متن کاملThe Transcription Factor EB (TFEB) Regulates Osteoblast Differentiation Through ATF4/CHOP-Dependent Pathway.
Osteoblasts are bone-forming cells that produce large amounts of collagen type I and various bone matrix proteins. Although osteoblast differentiation is highly regulated by various factors, it remains unknown whether lysosomes are directly involved in osteoblast differentiation. Here, we demonstrate the transcription factor EB (TFEB), a master regulator of lysosomal biogenesis, modulates osteo...
متن کاملTranscription Factor EB Controls Metabolic Flexibility during Exercise
The transcription factor EB (TFEB) is an essential component of lysosomal biogenesis and autophagy for the adaptive response to food deprivation. To address the physiological function of TFEB in skeletal muscle, we have used muscle-specific gain- and loss-of-function approaches. Here, we show that TFEB controls metabolic flexibility in muscle during exercise and that this action is independent ...
متن کاملTranslocational renal cell carcinoma (t(6;11)(p21;q12) with transcription factor EB (TFEB) amplification and an integrated precision approach: a case report.
INTRODUCTION Renal cell carcinoma with the distinct type of t(6;11)(p21;q12) translocation (transcription factor EB) is a rare neoplasm. In the present case study, we show for the first time an autophagy signature in a patient with transcription factor EB renal cell carcinoma. We attempted to characterize the mutational and expressional features of a t(6;11)(p21;q12) renal cell carcinoma, in an...
متن کاملDecorin-evoked paternally expressed gene 3 (PEG3) is an upstream regulator of the transcription factor EB (TFEB) in endothelial cell autophagy
Macroautophagy is a fundamental and evolutionarily conserved catabolic process that eradicates damaged and aging macromolecules and organelles in eukaryotic cells. Decorin, an archetypical small leucine-rich proteoglycan, initiates a protracted autophagic program downstream of VEGF receptor 2 (VEGFR2) signaling that requires paternally expressed gene 3 (PEG3). We have discovered that PEG3 is an...
