[Ruyiping Inhibited Pulmonary Metastasis of Breast Cancer by Regulating the Formation of Pre-metastasis Microenvironment].

Objective To observe the effect of Ruyiping (RYP, a recipe for fighting against re- currence and metastasis of breast cancer) on pre-metastatic microenvironment, and to study its possi- ble mechanism. Methods The experiment was divided into two parts. The 1st part lies in setting the pre- cancerous transfer, and the 2nd part lies in the effect of RYP on pre-metastatic microenvironment.

[Effects of platycodin D in combination with different active ingredients of Chinese herbs on proliferation and invasion of 4T1 and MDA-MB-231 breast cancer cell lines].

Objective: To investigate the effects of platycodin D in combination with different active ingredients of Chinese herbs under different therapeutic principles on proliferation and invasion of 4T1 and MDA-MB-231 breast cancer cell lines.

Methods: The effective doses of platycodin D, Ophiopogon total saponins, curcumenol and osthole in inhibiting proliferation of breast cancer cell lines 4T1 and MDA-MB-231 were detected by methyl thiazolyl tetrazolium (MTT) assay, respectively. Optimized combinations of platycodin D with Ophiopogon total saponins, curcumenol, or osthole were determined by uniform design method.

[Inhibitory effects of osthole, psoralen and aconitine on invasive activities of breast cancer MDA-MB-231BO cell line and the mechanisms].

Objective: To explore the inhibitory effects and to investigate the mechanisms of combined treatment of osthole, psoralen with aconitine on human breast cancer cell line MDA-MB-231BO.

Methods: The best inhibitory concentration of osthole, psoralen combined with aconitine on MDA-MB-231BO cells was obtained by stepwise regression analysis after adopting a uniform experiment design. The invasive activities were observed by transwell assays, and expressions of transforming growth factor-β1 (TGF-β1), Smad2, Smad3, Smad4, Smad7, nuclear factor-κB (NF-κB) and receptor activator of NF-κB ligand (RANK) mRNAs were analyzed by real-time quantitative polymerase chain reaction.

Hesperidin upregulates heme oxygenase-1 to attenuate hydrogen peroxide-induced cell damage in hepatic L02 cells.

Hesperidin, a naturally occurring flavonoid presents in fruits and vegetables, has been reported to exert a wide range of pharmacological effects that include antioxidant, anti-inflammatory, antihypercholesterolemic, and anticarcinogenic actions. However, the cytoprotection and mechanism of hesperidin to neutralize oxidative stress in human hepatic L02 cells remain unclear. In this work, we assessed the capability of hesperidin to attenuate hydrogen peroxide (H(2)O(2))-induced cell damage by augmenting the cellular antioxidant defense.
