S2B). Furthermore, the combined treatment synergistically decreased the number of viable cells. Results showed that HEV infection induced autophagy in Huh7 cells. When added separately, chloroquine or high concentrations of bafilomycin A1 (≥10 nM) induced a dose-dependent inhibition of autophagy (as measured by an increase in LC3-II, a marker specific for autophagosomes), followed by caspase-3 activation and cell death To investigate the effect of chloroquine on FIP-gts-induced autophagy, expressions of beclin-1, p62 and LC3-II were detected by Western blot assay. S‐Adenosylmethionine‐mediated apoptosis is potentiated by autophagy inhibition induced by chloroquine in human breast cancer cells. Treatment with Δ9-Tetrahydrocannabinol (THC) resulted in the activation of autophagy, loss of cell viability, and activation of apoptosis, whereas cotreatment with chloroquine or knockdown of Atg7, but not Beclin-1 or Ambra1, prevented chloroquine induced autophagy THC-induced autophagy and cell death in vitro Polycystic ovary syndrome (PCOS) is a clinical syndrome characterized by hyperandrogenism, oligo/anovulation, and polycystic ovary. Int Immunopharmacol. However, its effect on ischemic endothelial cells remains unclear.

Both cancer cells and kidney proximal tubular cells tolerate cisplatin through the use of autophagy because autophagy protects cells, not only from DNA damage, but also from the mitochondrial reactive oxygen species induced by the … Cited by: 401 Publish Year: 2013 Author: Tomonori Kimura, Yoshitsugu Takabatake, Atsushi Takahashi, Yoshitaka Isaka The Roles of Therapy-Induced Autophagy and Necrosis in https://clincancerres.aacrjournals.org/content/13/24/7271 Dec 15, 2007 · In Myc-driven lymphomas in which tumor regression was initiated with either p53 activation or alkylating chemotherapy, either chloroquine treatment or knockdown of the essential autophagy gene ATG5 resulted in a similar enhancement of therapy-induced apoptosis. The capability of this molecule to induce alkylation, not only on DNA but also on proteins and cell structures, could be the principle responsible for autophagy induction During the autophagy process, LC3-I is converted to LC3-II by lipidation, resulting in LC3-II migrating differently on SDS/PAGE. CQ provoked a lysosomal impairment intrinsically related to reduced proliferation and death in human carcinoma cells (HeLa, HT29, HepG2, and MCF7), as also melanomas SKMEL-25 and SKMEL-28. This study suggested that autophagy inhibition may have a role not only in combination therapies for patients with active metastatic disease, but also in the prevention of early disease The Cinchona alkaloid scaffold was synthetically merged with the indole ring system, and the bioactivities of the products in phenotypic assays revealed a novel class of autophagy ….
