    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.

    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. Aug 23, 2017 In order to determine the in vivo antitumor effects of chloroquine on OSCC, a CAL27 xenograft model was used. The results demonstrated that chloroquine markedly inhibited the proliferation and the colony‑forming ability of both OSCC cell lines in a dose‑ and time‑dependent manner in vitro. Chloroquine. Chloroquine Sigma-Aldrich, St. Louis, MO is one of many compounds which have shown to reverse autophagy by accumulating in lysosomes, disturbing the vacuolar H+ ATPase, which is responsible for lysosomal acidification and blocking autophagy.

    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. Once trapped within lysosomes, CQ raises intra lysosomal pH and interferes with autophagosome-lysosome fusion events 7. This unique property has established CQ as the most widely used drug to sensitize cancer cells through inhibiting autophagy in vitro and in vivo 2,6.

    In vivo treatment in combination with gemcitabine was capable of more effectively eliminating established tumors and improved overall survival. The inhibitory effect of chloroquine was not related to inhibition of autophagy, but was due to inhibition of CXCL12/CXCR4 signaling, resulting in reduced phosphorylation of ERK and STAT3. Nov 15, 2015 Chloroquine is commonly used to study the role of endosomal acidification in cellular processes 2, 3, such as the signaling of intracellular TLRs. Moreover, Chloroquine inhibits autophagy as it raises the lysosomal pH, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation 4. Autophagy in articular cartilage. Conclusion. Glucosamine modulates molecular targets of the autophagy pathway in vitro and in vivo, and the enhancement of autophagy is mainly dependent on the Akt/FoxO/mTOR pathway. These findings sug-gest that glucosamine is an effective autophagy activator and should motivate future studies on the efficacy of
