Comprehensive Genomic Analysis of Puerarin in Inhibiting Bladder Urothelial Carcinoma Cell Proliferation and Migration.

Background: Bladder urothelial carcinoma (BUC) ranks second in the incidence of urogenital system tumors, and the treatment of BUC needs to be improved. Puerarin, a traditional Chinese medicine (TCM), has been shown to have various effects such as anti-cancer effects, the promotion of angiogenesis, and anti-inflammation. This study investigates the effects of puerarin on BUC and its molecular mechanisms.

Expression of mTOR/70S6K signaling pathway in pathological scar fibroblasts and the effects of resveratrol intervention.

The aim of the study was to examine the expression of mammalian target of rapamycin (mTOR)/70S6K signaling pathway in pathological scar fibroblasts and the effects of resveratrol (Res) intervention. The mTOR and 70S6K in pathological scar and normal skin fibroblasts were detected by immunofluorescence following treatment with different concentrations of Res. RT-PCR and western blot analysis were used to detect the expression of mTOR and 70S6K mRNA and protein, respectively.

Expression of TGF-β1/mTOR signaling pathway in pathological scar fibroblasts.

The aim of the present study was to detect the expression of the key molecules, including transforming growth factor‑β1 (TGF-β1), phosphatidylinositol 3-kinase (PI3K), protein kinase B (Akt) of TGF‑β1/mammalian target of rapamycin (mTOR) pathway in pathological scar fibroblasts. Immunofluorescence, reverse transcription‑polymerase chain reaction (RT‑PCR) and western blot analysis were used to detect the expression of the key molecules TGF‑β1, PI3K, Akt, mTOR in fibroblasts of normal skin tissue and pathological scar tissue. Immunofluorescence showed that the expression of TGF‑β1, PI3K and Akt was significantly enhanced (P<0.

Effect of Wubeizi ointment aqueous solution on the expression of type I and III procollagen genes in keloid fibroblasts.

We evaluated the effect of Wubeizi (WBZ) ointment on keloids. Keloid-derived fibroblast primary cultures were used to evaluate the effect of the different concentration of WBZ ointment on the expression of type I and III procollagen in keloid fibroblast primary cultures using dot blot assay. Type I and II precollagen cDNA probes labeled with non-radioactive digoxin were used for dot blot.

Effects of resveratrol on the expression of molecules related to the mTOR signaling pathway in pathological scar fibroblasts.

Background: We observed the effects of resveratrol on the expression of molecules involved in the mTOR signaling pathway in pathological scar fibroblasts, including PI3K, Akt and mTOR.

Methods: We detected the expression of PI3K, Akt and mTOR in pathological scar and normal skin fibroblasts through immunofluorescence. After being treated with different concentrations of resveratrol, the expression of PI3K, Akt and mTOR mRNA and protein were detected by RT-PCR and Western Blot respectively.

Effects of resveratrol on the proliferation, apoptosis and telomerase ability of human A431 epidermoid carcinoma cells.

The aim of the present study was to investigate the effect of resveratrol on cell apoptosis, ability of telomerase and the human telomerase reverse transcriptase (hTERT) protein expression in human A431 epidermoid carcinoma cells. A431 cells were treated with different concentrations of resveratrol, and the cell appearance was then observed under a microscope. In addition, the cell proliferation was examined using an MTT assay, and the ability of telomerase was detected using telomeric repeat amplification protocol-polymerase chain reaction-ELISA.

Resveratrol Inhibits Proliferation and Induces Apoptosis of Pathological Scar Fibroblasts Through the Mechanism Involving TGF-β1/Smads Signaling Pathway.

The objective of this study was to determine the effect of resveratrol (Res) treatment on pathological scar fibroblasts and the changes in TGF-β1/Smads signaling pathway. For this purpose, cultured pathological scar fibroblasts were treated with various concentrations of Res (10, 50, and, 100 µmol/l), and the morphological changes in target cells were studied using scanning electron microscopy (SEM). The cellular proliferation was assessed by MTT assay; the mRNA and protein expressions of TGF-β1 and Smad-2,3,4,7 were determined by reverse transcription polymerase chain reaction (RT-PCR) and immunofluorescence assay, respectively.

The effects of Wubeizi ointment on the proliferation of keloid-derived fibroblasts.

Unlabelled: To evaluate the effectiveness of the Wubeizi (WBZ) ointment on keloid-derived fibroblasts. The primary cells of the keloid-derived fibroblasts were cultured and the effectiveness of the WBZ ointment at different concentrations was examined by MTT colorimetric methods on keloid-derived fibroblasts. The WBZ ointment showed inhibitory effects on proliferating the keloid-derived fibroblasts (P < 0.
