Cell-type-specific responses to chemotherapeutics in breast cancer.
Recent microarray studies have identified distinct subtypes of breast tumors that arise from different cell types and that show statistically significant differences in patient outcome. To gain insight into these differences, we identified in vitro and in vivo changes in gene expression induced by chemotherapeutics. We treated two cell lines derived from basal epithelium (immortalized human mam...
متن کاملUse of Targeted Liposome-based Chemotherapeutics to Treat Breast Cancer
The use of nanocarriers such as liposomes to deliver anticancer drugs to tumors can significantly enhance the therapeutic index of otherwise unencapsulated cytotoxic agents. This is in part because of the fact that the phospholipid bilayer can protect healthy sensitive tissue from the damaging effects of these types of drugs. Furthermore, the ease with which the phospholipid bilayer surface can...
متن کاملPRODUCTIO N OF PROSTATE-SPECIFIC ANTIGEN (PSA) BY A BREAST CANCER CELL LINE, SK-Br-3
PSA is a 33-KDa serine protease that is produced predominantly by prostate epithelium. However, it has been shown that about 30-40% of female breast tumors produce PSA and its production is associated with the presence of estrogen and progesterone receptors. We have now developed a new tissue culture system to study PSA production in breast cancer and its association with prognostic factors...
متن کاملAutophagic Cell Death and Cancer Chemotherapeutics
Autophagy usually functions in cell-protective events. However, it may also be utilized as a cell-suicide mechanism, which is known as “autophagic cell death.” Autophagic cell death is frequently induced in cells that lack apoptotic machinery, such as p53-defi cient cancer cells. Therefore, small compounds that activate autophagic cell death are good candidates for anticancer chemotherapeutics ...
متن کاملSulforaphane induces cell type-specific apoptosis in human breast cancer cell lines.
Sulforaphane, an isothiocyanate found in cruciferous vegetables, has been shown to induce phase 2 detoxication enzymes and inhibit the growth of chemically induced mammary tumors in rats, although the exact mechanisms of action of sulforaphane are not understood. In this study, we evaluated the effects of sulforaphane on cell growth and death in several human breast cancer cell lines and examin...
