    Chloroquine and breast cancer


    To date, it was assumed that chloroquine increases the sensitivity of cancer cells to chemotherapy by means of a direct effect on the cancer cells. However, a recent study has demonstrated that chloroquine also normalizes the abnormal blood vessels in tumors.

    Breast Cancer. The first evidence of how genetic inactivation of autophagy can contribute to the malignant transformation in breast cancer was made by Liang and colleagues in 1999. They showed that Beclin1 expression is frequently low in human breast epithelial carcinoma cell lines and tissues, but expressed at high levels in normal breast epithelia. The anti-malarial chloroquine overcomes Primary resistance and restores sensitivity to Trastuzumab in HER2-positive breast cancer Skip to main content Thank you for visiting This review discusses the versatile actions of chloroquine in cancer cells with particular focus on glioma cells. Chloroquine, one of the oldest antimalarials, has been implicated as a therapeutic sensitizer in different types of cancers.

    The anti-cancer effect of the antimalarial agent chloroquine when combined with conventional chemotherapy has been well documented in experimental animal models. This blood vessel normalization results in an increased barrier function on the one hand, and in enhanced tumor perfusion on the other hand, which increases the response of the tumor to chemotherapy.

  5. Chloroquine CQ is a well known, well tolerated medication that has been used for many years traditionally for arthritis, lupus, and malaria. It has anti-inflammatory properties but is often the drug of choice for arthritis and malaria due to its few side effects.

    In the ZR-75 model of human breast cancer, vitamin D sensitized the cells to ionizing radiation by inducing a switch between protective autophagy in response to radiation alone to the cytotoxic form of autophagy that resulted in significant decrease in cell number without a concomitant increase in apoptosis. In MCF-7 cells, radiation induced cytoprotective autophagy, the blockade of which by Chloroquine resulted in decreased colony formation and increased apoptosis. Chloroquine's potential chemosensitizing and radiosensitizing activities in cancer may be related to its inhibition of autophagy, a cellular mechanism involving lysosomal degradation that minimizes the production of reactive oxygen species ROS related to tumor reoxygenation and tumor exposure to chemotherapeutic agents and radiation. The excretion of Chloroquine and the major metabolite, desethylChloroquine, in breast milk wasinvestigated in eleven lactating mothers following a single oral dose of Chloroquine 600 mg base. The maximum daily dose of the drug that the infant can receive from breastfeeding was about 0.7% of the maternal start dose of the drug in malaria chemotherapy.
