Tanshinone IIA attenuates high glucose-induced epithelial-to-mesenchymal transition in HK-2 cells through VDR/Wnt/ β-catenin signaling pathway
CONCLUSIONS: TSIIA was able to attenuate high glucose-induced EMT in HK2 cells by up-regulating VDR levels, which might be related to the inhibitory effect of VDR on the Wnt pathway.PMID:34852178 | DOI:10.5603/FHC.a2021.0025

Up-regulation of heme oxygenase-1 by celastrol alleviates oxidative stress and vascular calcification in chronic kidney disease
Free Radic Biol Med. 2021 Jun 23:S0891-5849(21)00385-3. doi: 10.1016/j.freeradbiomed.2021.06.020. Online ahead of print.ABSTRACTVascular calcification is very commonly observed in patients with chronic kidney disease (CKD), but there is no efficient therapy available. Oxidative stress plays critical roles in the progression of vascular calcification. Celastrol (Cel), a natural constituent derived from Chinese herbals, exhibits anti-oxidative stress activity. Here, we investigated the effect of celastrol on vascular calcification using vascular smooth muscle cells (VSMCs), arterial rings and CKD rats. Alizarin red staining ...

Astragalus improve aging bone marrow mesenchymal stem cells (BMSCs) vitality and osteogenesis through VD-FGF23-Klotho axis.
This study confirmed that astragalus could inhibit the aging of BMSCs and improve the osteogenesis ability by regulating the VD-FGF23-Klotho pathway. This study provided a certain research basis for the therapeutic of traditional Chinese medicine (TCM) on primary osteoporosis. PMID: 32355520 [PubMed]

Antifibrotic action of Yifei Sanjie formula enhanced autophagy via PI3K-AKT-mTOR signaling pathway in mouse model of pulmonary fibrosis
Publication date: October 2019Source: Biomedicine & Pharmacotherapy, Volume 118Author(s): Jing-Ze Yu, Yi Ying, Yang Liu, Chun-Bin Sun, Chen Dai, Shan Zhao, Shou-Zheng Tian, Jing Peng, Ni-Ping Han, Jia-Li Yuan, Jin-Yuan Yan, Zhong-Shan YangAbstractPulmonary fibrosis (PF) is a crippling disease characterized by progressive dyspnea and associated with a high mortality rate, but its origin is unknown and there is no effective treatment. Yifei Sanjie formula (YFSJF) is a Chinese medicine that is widely used for treatment of respiratory systems disease. However, the molecular basis for the function of YFSJF has not been determin...

Plant-Derived Alkaloids: The Promising Disease-Modifying Agents for Inflammatory Bowel Disease
Conclusion This paper summarizes the current findings regarding the anti-colitis activity of plant-derived alkaloids and shows how these alkaloids exhibit significant and beneficial effects in alleviating colonic inflammation. These natural alkaloids are not only promising agents for IBD treatment but are also components for developing new wonder drugs. However, the underlying molecular mechanisms or toxicological evaluation of most plant-derived alkaloids still require much scientific research, and their actual efficacies for IBD patients have not been verified well in field research. Thus, further clinical trials to elu...
