Establishment of a human neonatal hepatocyte cell line.

Hepatocytes are routinely used to generate and identify drug metabolites and hepatic toxicity. Primary cultures of human hepatocytes are the model cell of choice for most of these pharmacological and toxicological studies. However, major problems are encountered with primary liver cell cultures: the dwindling availability of viable livers, hepatocytes having a limited life span, the loss of liver-specific functions in culture, and the donor to donor variability.

Picroliv accelerates epithelialization and angiogenesis in rat wounds.

Tissue repair and wound healing are complex processes that involve inflammation, granulation and tissue remodeling. Angiogenesis plays a central role in wound healing. Earlier, we have shown that picroliv, a natural product obtained from the roots of Picrorhiza kurrooa, up-regulates the expression of vascular endothelial growth factor in human umbilical vein endothelial cells and of insulin-like growth factor in rats during hypoxia.

Inhibition of tumor angiogenesis by Brahma Rasayana (BR).

The current therapy for prostate cancer includes radical prostatectomy, radiation therapy and hormonal ablation. Chemotherapy also provides beneficial results for some patients with advanced prostate cancer but with several harmful side effects. Hence there is a need to identify and develop alternate therapies, which can reduce the disease progression with minimal or few side effects.

Homeopathic medicines do not alter growth and gene expression in prostate and breast cancer cells in vitro.

Background: Homeopathy is an alternative medical system practiced in all parts of the world. Although several theories are proposed to explain the mechanisms of action, none are scientifically verified. In this study, the authors investigate the effect of selected homeopathic remedies often used to treat prostate and breast cancer.

Effect of homeopathic treatment on gene expression in Copenhagen rat tumor tissues.

Background: Increasing evidence suggests that the inability to undergo apoptosis is an important factor in the development and progression of prostate cancer. Agents that induce apoptosis may inhibit tumor growth and provide therapeutic benefit. In a recent study, the authors found that certain homeopathic treatments produced anticancer effects in an animal model.
