Synergistic cytotoxic effects of tamoxifen and black cohosh on MCF-7.

Cytotoxic drugs are used widely in healthcare settings as well as in the community in the treatment of cancers as well as other diseases. This page provides information to employers and employees on the occupational hazards associated with cytotoxic drugs and the precautions to take when handling them. It is not aimed at manufacturers of cytotoxic drugs. Cytotoxic drugs (sometimes known as antineoplastics) describe a group of medicines that contain chemicals which are toxic to cells, preventing their replication or growth, and so are used to treat cancer. They can also be used to treat a number of other disorders such as rheumatoid arthritis and multiple sclerosis. Once inside the body, their action is not generally tightly targeted, and they can produce side effects both to the patients and others who become exposed. They are used in range of settings including; hospitals, specialist oncology units, hospices, care homes, charitable organisations, and domestic homes. The toxicity of cytotoxic drugs means that they can present significant risks to those who handle them. If your browser does not accept cookies, you cannot view this site.

In some cases, health care professionals may use the trade name Nolvadex when referring to the generic drug name tamoxifen. This medication is classified as an "anti-estrogen." (For more detail, see "How this drug works" section below). You should seek emergency help and notify your health care provider immediately if you develop sudden chest pain and shortness of breath. Notify your health care provider within 24 hours if you notice that one leg is swollen, red, painful and/or warm to touch and the other is not. A side effect of tamoxifen can be the development of uterine cancer. Women who have not had a hysterectomy should have regular pap smears and gyn examinations. Abnormal vaginal bleeding should be reported to your health care provider.

Tamoxifen enhances the cytotoxic effects of nelfinavir in.

The HIV protease inhibitor nelfinavir is currently under investigation as a new anti-cancer drug. Several studies have shown that nelfinavir induces cell cycle arrest, endoplasmic reticulum stress, autophagy, and apoptosis in cancer cells. In the present article, the effect of nelfinavir on human breast cancer cells is examined and potential combination treatments are investigated. The effects of nelfinavir and tamoxifen on the human breast cancer cell lines MCF7, T47 D, MDA-MB-453, and MDA-MB-435 were tested by analysing their influence on cell viability (via 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay), apoptosis (annexin binding, poly(ADP-ribose) polymerase cleavage), autophagy (autophagy marker light chain 3B expression), endoplasmic reticulum stress (binding protein and activating transcription factor 3 expression), and the occurrence of oxidative stress (intracellular glutathione level). Nelfinavir induced apoptosis in all four breast cancer cell lines tested, although the extent of autophagy and endoplasmic reticulum stress varied among the cell lines. The concentration of nelfinavir needed for an efficient induction of apoptosis in breast cancer cells could be reduced from 15 μg/ml to 6 μg/ml when combined with tamoxifen. At a concentration of 6 μg/ml, tamoxifen substantially enhanced the endoplasmic reticulum stress reaction in those cell lines that responded to nelfinavir with binding protein (Bi P) upregulation (MCF7, T47D), and enhanced autophagy in cell lines that responded to nelfinavir treatment with autophagy marker light chain 3B upregulation (MDA-MB-453). Tamoxifen (TAM) is a non-steroidal anti-estrogen used to treat patients with estrogen receptor-positive breast cancer and as a chemopreventive agent against breast cancer in high risk pre- and post-menopausal women. However, recent studies have shown that tamoxifen causes endometrial and hepatic cancer. In this study, we examined the effects of tamoxifen (5, 10, 25 and 50 μM) on the growth and proliferation of nine tumoral cell lines (UACC62, MCF-7, NCI-460, K-562, OVCAR-03, PC-03, HT-29, 786-0, NCI-ADR) and non-tumoral cell lines (3T3, V79, MDCK, VERO). Chinese hamster lung fibroblasts (V79) were the most sensitive lineage to tamoxifen, with 21.6% of the cells showing apoptosis at 50 μM TAM. Microscopic analysis showed that, the cellular transformation caused by TAM in V79 cells was similar to that seen with 7,12-dimethylbenz(a)anthracene, thus indicating the carcinogenicity of TAM.

ABSTRACT. The cytokinetic and cytotoxic interactions involved in combin ing tamoxifen, methotrexate, and 5-fluorouracil were studied in. Dec 29, 1988. Because it involved several thousand women, this overview was able to demonstrate particularly clearly that both tamoxifen and cytotoxic.
