Imidazole inhibits autophagy flux by blocking autophagic degradation and triggers apoptosis via increasing FoxO3a-Bim expression.
Imidazole, an organic alkaloid, is an important pharmacophore in drug discovery. Anti-neoplastic potential of imidazole derivatives has been documented in several studies; however, mechanisms by which tumor cells respond to these stimuli remain to be elucidated. Autophagy and apoptosis have key roles in tumorigenesis and tumor treatment. In this study, we systematically examined autophagic even...
متن کاملEnhancing lysosomal biogenesis and autophagic flux by activating the transcription factor EB protects against cadmium-induced neurotoxicity
Cadmium (Cd), a highly ubiquitous heavy metal, is a well-known inducer of neurotoxicity. However, the mechanism underlying cadmium-induced neurotoxicity remains unclear. In this study, we found that Cd inhibits autophagosome-lysosome fusion and impairs lysosomal function by reducing the levels of lysosomal-associated membrane proteins, inhibiting lysosomal proteolysis and altering lysosomal pH,...
متن کاملProtection against neurotoxicity by an autophagic mechanism
The objective of the present study was to investigate the effects of 3-n-butylphthalide (NBP) on a 1-methyl-4-phenylpyridinium (MPP+)-induced cellular model of Parkinson's disease (PD) and to illustrate the potential mechanism of autophagy in this process. For this purpose, rat PC12 pheochromocytoma cells were treated with MPP+ (1 mM) for 24 h following pretreatment with NBP (0.1 mM). Cell meta...
متن کاملAneuploidy-induced cellular stresses limit autophagic degradation.
An unbalanced karyotype, a condition known as aneuploidy, has a profound impact on cellular physiology and is a hallmark of cancer. Aneuploid cells experience a number of stresses that are caused by aneuploidy-induced proteomic changes. How the aneuploidy-associated stresses affect cells and whether cells respond to them are only beginning to be understood. Here we show that autophagosomal carg...
متن کاملInfluenza A virus lures autophagic protein LC3 to budding sites.
Autophagy, a cellular degradation pathway, can restrict or assist viral replication. In this issue of Cell Host & Microbe, Beale et al. (2014) report that the influenza virus matrix protein 2 binds to the essential autophagy protein LC3 to presumably transport LC3-conjugated membranes to the cell surface for budding of stable viruses.
