here, we show that the natural product honokiol significantly inhibited csa-induced and ras-mediated survival of renal cancer cells through the down-regulations of vegf and ho-1. it has been demonstrated that honokiol can inhibit the growth of tumors in animal xenograft models and induce tumor cell apoptosis [21-23]. after 18 hours of transfection, the cells were treated with different combinations of csa and honokiol. the cells were washed and resuspended in 200 μl of binding buffer. to study promoter activity, cells were transfected with the vegf promoter-luciferase plasmid and then treated with csa in absence or presence of honokiol. we have recently demonstrated that the ras-raf pathway activates nrf2 to promote the over-expression of ho-1 in renal cancer cells .
the cell were treated with csa in absence or presence of honokiol, and subjected to cell proliferation assay. the cells were treated with different combinations of honokiol and copp (ho-1 inducer), and then subjected to apoptosis assay as described earlier. here, we show that honokiol can effectively inhibit csa-induced transcriptional activation and over-expression of vegf in renal cancer cells. in summary, honokiol can inhibit csa-induced survival of renal cancer cells by targeting the ras pathway, and suppressing the induction of vegf and ho-1. the cells were harvested 48 h after transfection and fold change in luciferase activity was calculated as the relative luciferase counts from each group of cells compared to that of vehicle-treated control. the cells were harvested 48 h after transfection and fold change in luciferase activity was calculated as the relative luciferase counts from each group of cells compared to that of vehicle-treated control. the over-expression of ho-1 in copp-treated cells and the knockdown of ho-1 in sirna-transfected cells was confirmed by western blot (a and b, bottom panel).
although the nih and nccam have begun funding studies examining cam practices, it is important for pediatricians to realize that patients continue to consume cam in large numbers despite a lack of clinical evidence. hon and colleagues report a recent case of an 11-year-old girl in which cam was potentially harmful.8 the girl had ad that was difficult to control and a previous history of treatment noncompliance. although many patients assume that the term “natural” in the description of a cam product means “safe,” this is not necessarily so. studies evaluating epo and bo have demonstrated mixed results, and their use in the treatment of ad remains controversial. despite a number of individual studies demonstrating benefit, the overall benefit and efficacy of cam for ad is yet to be determined.

honokiol, a small molecular weight polyphenol, is a promising agent for its anti-tumor and anti-carcinogenic properties. in this study, we show long-term use of topical steroids can lead to skin atrophy, depigmentation, and telangiectasia. topical calcineurin inhibitors may lead to skin topical calcineurin inhibitors block calcineurin, a naturally produced chemical that activates t-cells. t-cells are a type of white blood cell, related health topics, related health topics, honokiol.
agents discussed include andrographis paniculata (kalmegh) leaf, silybum marianum (milk thistle) seed, silymarin, silibinin, liv.52 formula, topical calcineurin inhibitors (tcis) work by altering the immune system and have been developed for treating atopic eczema. there are two types available: calcineurin inhibitors (cnis) revolutionized the field of organ transplantation and remain the standard of care 40 years after the discovery, .
