    Chloroquine autophagy in vivo


    Note: based on a RGCC chemosensitivity analysis I have seen at a German clinic, Hydroxychloroquine has been effective in killing the cancer cells of 5 out 7 patients that were tested. It is one of very few available drugs that inhibits autophagy, a mechanism associated with its anticancer properties.

    How can I monitor autophagy in vivo . I am aware that chloroquine is used in the autophagy field to block the degradation of autophagosomes in lysosomes. However, I am reading recent journals. Autophagy is a homeostatic cellular recycling system that is responsible for degrading damaged or unnecessary cellular organelles and proteins. Cancer cells are thought to use autophagy as a source of energy in the unfavorable metastatic environment, and a number of clinical trials are now revealing the promising role of chloroquine, an autophagy inhibitor, as a novel antitumor drug. On the. Herein, we report results of administration of rapamycin, a specific inhibitor of the mechanistic target of rapamycin mTOR signaling pathway, and chloroquine, a lysosomal inhibitor which reverses autophagy by accumulating in lysosomes, responsible for blocking autophagy in 20-month old VCPR155H/+ mice.

    In cancer, authophagy is the process used by cancer cells to “self-eat” in order to survive. Specifically, if authophagy is prolonged this will become a lethal process to cancer. duing chemotheraphy, radiotheraphy, etc.) authophagy is used by cancer cells to survive. However, note that Chloroquine has other properties as well that may be very well related to anti cancer mechanism, such as zinc ionophore, and others (see below the section on mechanisms).

  6. Aug 27, 2018 Up until recently, inhibitory effects of chloroquine on the late stage of autophagy was thought to be the major mechanism underlying cancer cells death from chloroquine. However, recent research provided compelling evidence that autophagy-inhibiting activities of chloroquine are dispensable for its ability to suppress tumor cells growth.

    Autophagy plays a crucial role in cancer cell survival and the inhibition of autophagy is attracting attention as an emerging strategy for the treatment of cancer. Chloroquine CQ is an anti-malarial drug, and is also known as an inhibitor of autophagy. Recently, it has been found that CQ induces cancer cell death through the inhibition of autophagy; however, the underlying mechanism is not. Another study also showed that inhibition of late‐stage autophagy by chloroquine and Rab7 knockdown, but not early‐stages autophagy by 3‐MA and Beclin‐1 knockdown, enhanced the cytotoxicity of an autophagy‐inducing drug, arsenic trioxide, in glioblastoma multiforme cell lines Li et al. 2015a. These findings suggest that the. Tumor cells require autophagy to remove misfolded proteins or damaged cellular organelles. SBI-0206965 was shown to suppress autophagy induced by mTOR inhibition. mTOR signaling is often hyperactive in many tumors and can drive proliferation, so mTOR inhibitors are being investigated as anticancer agents.
