How does chloroquine affect autophagy?
Chloroquine in combination with radiation inhibited the autophagy induced by radiation and strongly promoted GICs apoptosis. Apoptosis involved many diseases, especially malignant tumors. There are two main apoptotic pathways: the extrinsic or death receptor pathway and intrinsic or mitochondrial pathways [20].
Is hydroxychloroquine FDA approved for autophagy?
them, only CQ and its derivate hydroxychloroquine (HCQ) are FDA-approved drugs and are thus currently the principal compounds used in clinical trials aimed to treat tumors through autophagy
Does chloroquine promote autophagy in U87 glomerular insulin-induced cancer?
Our data indicates that irradiation of U87 GICs results in enhanced autophagy. Chloroquine in combination with radiation inhibited the autophagy induced by radiation and strongly promoted GICs apoptosis. Apoptosis involved many diseases, especially malignant tumors.
Is CQ a proteolytic agent in autophagy?
on the autophagy pathway showed that the proteolytic activity in isolated autophagic vesicles from cells treated with this compound, is even higher than in the control cells, underlying that the degradative capacity of the cells still remains intact especially upon short exposure times to CQ [63,64]. It is
How does chloroquine block autophagosome fusion with lysosome?
Chloroquine, an anti-malarial chemical, is an autophagic inhibitor which blocks autophagosome fusion with lysosome and slows down lysosomal acidification. The aim of this study was to explore the mechanisms of chloroquine on the radiosensitivity of GICs.
How does CQ block autophagic flux?
CQ blocks the autophagic flux by impairing autophagosome-lysosome fusion Because our data were indicating that the autophagy inhibition mechanism of CQ is not analogous to that of BafA1, we designed a series of specific experiments to identify which step of autophagy is inhibited by CQ.
