Inhibition of MTOR disrupts autophagic flux in podocytes.
Inhibitors of the mammalian target of rapamycin (MTOR) belong to a family of drugs with potent immunosuppressive, antiangiogenic, and antiproliferative properties. De novo or worsening proteinuria can occur during treatment with these agents, but the mechanism by which this occurs is unknown. We generated and characterized mice carrying a podocyte-selective knockout of the Mtor gene. Although M...
متن کاملPhysiological difference in autophagic flux in macrophages from 2 mouse strains regulates cholesterol ester metabolism.
OBJECTIVE DBA/2 apoE(-/-) mice have ≈10-fold larger lesions than AKR apoE(-/-) mice. The objective of this study was to determine whether macrophages from these 2 strains had altered cholesterol metabolism that might play a role in their divergent atherosclerosis susceptibility. APPROACH AND RESULTS AKR and DBA/2 macrophages incubated with acetylated low-density lipoprotein resulted in higher...
متن کاملThe Drosophila effector caspase Dcp-1 regulates mitochondrial dynamics and autophagic flux via SesB
Increasing evidence reveals that a subset of proteins participates in both the autophagy and apoptosis pathways, and this intersection is important in normal physiological contexts and in pathological settings. In this paper, we show that the Drosophila effector caspase, Drosophila caspase 1 (Dcp-1), localizes within mitochondria and regulates mitochondrial morphology and autophagic flux. Loss ...
متن کاملSirt1 regulates acrosome biogenesis by modulating autophagic flux during spermiogenesis in mice.
Sirt1 is a member of the sirtuin family of proteins and has important roles in numerous biological processes. Sirt1-/- mice display an increased frequency of abnormal spermatozoa, but the mechanism of Sirt1 in spermiogenesis remains largely unknown. Here, we report that Sirt1 might be directly involved in spermiogenesis in germ cells but not in steroidogenic cells. Germ cell-specific Sirt1 knoc...
متن کاملHalofuginone dually regulates autophagic flux through nutrient-sensing pathways in colorectal cancer
Autophagy has a key role in metabolism and impacts on tumorigenesis. Our previous study found that halofuginone (HF) exerts anticancer activity in colorectal cancer (CRC) by downregulating Akt/mTORC1 (mechanistic target of rapamycin complex 1) signaling pathway. But whether and how HF regulates autophagy and metabolism to inhibit cancer growth remains an open question. Here, we unveil that HF a...
