    Chloroquine and pancreatic cancer

    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 targets pancreatic cancer stem cells via inhibition of CXCR4 and hedgehog signaling. Balic A1, Sørensen MD2, Trabulo SM3, Sainz B Jr1, Cioffi M1, Vieira CR1, Miranda-Lorenzo I1, Hidalgo M4, Kleeff J5, Erkan M5, Heeschen C6. Usual Adult Dose for Malaria Prophylaxis. 500 mg chloroquine phosphate 300 mg base orally on the same day each week Comments -If possible, suppressive therapy should start 2 weeks prior to exposure; if unable to start 2 weeks before exposure, an initial loading dose of 1 g chloroquine phosphate. Jun 22, 2018 Chloroquine has been used for many years to treat patients with malaria, lupus, and rheumatoid arthritis, but more recently, hydroxychloroquine has been evaluated as a treatment for pancreatic cancer, with encouraging preliminary results.

    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).

    Chloroquine eliminates pancreatic cancer stem cells In an effort to identify more effective treatments against pancreatic CSCs, we established a novel low-throughput drug-screening platform for identifying compounds targeting CSCs unpublished observations; Irene Miranda-Lorenzo. Chloroquine is a lysosomotropic agent that inhibits auto-lysosomal clearance and it has been previously described that in combination with other chemotherapeutic agents, Chloroquine enhances their anti-cancer effects in several tumor types 21, 22. Hence, we have evaluated the effect of Chloroquine treatment in both primary PDAC derived cells and CAFs. Hydroxychloroquine is inexpensive; further, it has high oral bioavailability and has an established safety profile thanks to its use for treatment of malaria, lupus, and rheumatoid arthritis, thus facilitating its use in patients with pancreatic cancer.51, 52 Chloroquine functions as a lysosomal inhibitor by blocking acidification of the lysosome, thereby preventing fusion of the autophagosome, inhibiting breakdown of its contents and blocking autophagy. 53 Because it is a late inhibitor of.

    Chloroquine for research Cell-culture tested InvivoGen 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.

    Chloroquine Indications, Side Effects, Warnings - A severe eye problem has happened with chloroquine. This may lead to lasting eyesight problems. The risk may be higher if you have some types of eye or kidney problems. The risk may also be higher with some doses of chloroquine, if you use chloroquine for longer than 5 years, or if you take certain other drugs like tamoxifen.
