Abstract

Despite emerging new therapeutic opportunities, cancer is still a major health problem and a leading cause of death worldwide. Breast tumors are the most frequently diagnosed female malignancies, and the triple-negative subtype is associated with poorer prognosis and lower survival rates than other breast cancer types. The aims of the present study were to determine the anticancer potency of a set of C-3 and C-16 modified estradiol-derivatives against a panel of breast cancer cell lines, and to characterize the mechanism of action of two selected compounds (1 and 5) against the MDA-MB-231 triple-negative breast cancer cell line. Growth-inhibitory properties were investigated by an MTT-assay. Cell cycle analysis by flow cytometry has revealed G1 phase accumulation and indicated the proapoptotic effect of 1 and 5 through the elevation of the apoptotic subG1 phase on MDA-MB-231 cells after 24 h treatment. The antimetastatic activities of these compounds were examined by wound healing and Boyden chamber assays, and both compounds were shown to significantly inhibit the migration and invasion of MDA-MB-231 cells at sub-antiproliferative concentrations. Gelatin zymography assay has indicated that matrix metalloproteinase-2 and -9 are...Continue Reading

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Breast Cancer Triple-N

Breast cancer cells have receptors for estrogen, progesterone, HER2 receptors (also called ERBB2). Triple-negative breast cancers do not have any of these receptors. Here are the latest discoveries pertaining to triple-negative breast cancers.
