    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.

    Chloroquine phosphate displays synergy when combined with the Raf inhibitor, vemurafenib, in brain tumor 4. Cell permeable and active in vivo. References/Citations 1 Frieboes et al. 2014, Chloroquine-mediated cell death in metastatic pancreatic adenocarcinoma through inhibition of autophagy; JOP, 15 189 2 Jiang et al. 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. 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.

    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. Treatment of GBM xenografts in vivo with chloroquine CQ, an antimalarial agent, has been shown to reduce the hypoxic fraction and sensitizes tumors to radiation. Epidermal growth factor receptor EGFR amplification or mutation is regularly observed GBM and is thought to be a major contributor to radioresistance.

    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. Nov 14, 2013 Accurate methods to measure autophagic activity in vivo in neurons are not available, and most of the studies are based on correlative and static measurements of autophagy markers, leading to. Autophagy Inhibitors. Click to enlarge. Autophagy is an orchestrated homeostatic process to eliminate unwanted proteins and damaged organelles. The autophagic process is also used to remove intracellular microbial pathogens.
