Moxibustion Inhibits the ERK Signaling Pathway and Intestinal Fibrosis in Rats with Crohn's Disease
نویسندگان
چکیده
Intestinal fibrosis is the main pathological process in Crohn's disease (CD); acupuncture and moxibustion can inhibit the process of fibrosis in CD rats, but the regulatory mechanism remains unknown. The present study observed the effect of moxibustion on the extracellular signal-regulated kinase (ERK) signaling pathway in the CD rat. The result shows that the phosphorylation of the Ras, Raf-1, MEK-1, and ERK-1/2 proteins and the expression of the corresponding mRNAs in the colon tissue of CD rat were significantly higher than the normal control group. Both treatments with mild moxibustion and with herb-separated moxibustion significantly reduced the expression of the Ras, Raf-1, MEK-1, and ERK-1/2 proteins and Ras and Raf-1 mRNA. MEK-1 and ERK-1/2 mRNA expression in each treatment group showed a downward trend, and the ERK-1/2 mRNA levels were significantly lower in the mild moxibustion group. It indicates that Ras, Raf-1, MEK-1, and ERK-1/2 are involved in the process of intestinal fibrosis in CD rats. Moxibustion can downregulate the abnormal expression of colonic Ras, Raf-1, MEK-1, and ERK-1/2 protein and mRNA levels in CD intestinal fibrosis in rats. Moxibustion may play a role in the treatment of CD intestinal fibrosis by regulating ERK signaling pathway.

Moxibustion Alleviates Gastric Precancerous Lesions in Rats by Promoting Cell Apoptosis and Inhibiting Proliferation-related Oncogenes
BACKGROUND It is well known that gastric mucosa dysplasia and intestinal metaplasia are gastric precancerous lesions (GPL). Moxibustion treatment of Liangmen (ST21) and Zusanli (ST36) alleviated the inflammatory response and dysplasia of gastric mucosa in our previous study. The purpose of this study was to further examine the underlying mechanism of moxibustion treatment of ST21 and ST36 on GP...

Objective(s): Naringin has been reported to regulate bone metabolism. However, its effect on osteogenesis remains unclear. The aim was to investigate the effect of naringin on osteogenic differentiation of human bone marrow mesenchymal stem cells (hBMSCs) through the activation of the ERK signaling pathway in osteogenic differentiation. Materials and Methods: Annexin V-FITC assay and MTT assay ...

Background :The concept of survival has changed since the twentieth century to guarantee quality of life in the twenty-first century (1). Aging is associated with a certain degree of interstitial fibrosis, which progresses to heart failure. Therefore, finding new and practical methods is an important and necessary help to reduce heart tissue fibrosis in the elderly (2). Providing mechanisms by ...
