Mechanisms of chemotherapeutic drug resistance in cancer therapy--a quick review.

Chemotherapy is one of the principal modes of treatment for cancer patients. Clinically, many tumors present a satisfactory response when they are first exposed to the chemotherapeutic drugs. However, drug resistance occurs sooner or later in these tumors, and the majority of the patients develop progressive disease.

Expression analysis of apoptosis-related markers TP53, BCL-2, BAX and c-MYC in female genital tract sarcomas.

Background: Most female genital tract sarcomas are highly malignant and fatal. Their aggressive growth pattern and poor response to chemotherapy are the major causes of death. Deregulation of the apoptosis pathway is related to tumorigenesis and chemodrug resistance.

Undecylprodigiosin selectively induces apoptosis in human breast carcinoma cells independent of p53.

Undecylprodigiosin (UP) is a bacterial bioactive metabolite produced by Streptomyces and Serratia. In this study, we explored the anticancer effect of UP. Human breast carcinoma cell lines BT-20, MCF-7, MDA-MB-231 and T47D and one nonmalignant human breast epithelial cell line, MCF-10A, were tested in this study.

Molecular carcinogenesis of endometrial cancer.

In 1983, Bokhman proposed a dualistic model of endometrial tumorigenesis based on the clinical observations and clinicopathologic correlations. The majority of endometrial cancers (approximately 70-80%), designated as type I carcinomas, follow the estrogen-related pathway. Histologically, most of the type I tumors seem to arise in the background of hyperplastic endometrium, show an endometrioid differentiation, and are of low grade.
