Epub Jul Asiatic acid AAa pentacyclic triterpene derived from the tropical medicinal plant, has been widely used as an antioxidant and anti-inflammatory agent. Evidence regarding the neuroprotective properties of AA is emerging. However, the protective effects of AA and its mechanism in glaucoma are poorly understood.
Some of these reports also mentioned the ability of celastrol to inhibit tumor metastasis; nevertheless, to date, no study has described its anti-metastatic activities comprehensively, or characterized the underlying mechanisms profoundly.
In the current study, for the first time, we systematically evaluated the effects of celastrol represented in metastatic-related events including cell-ECM adhesion, migration, invasion, and development of pulmonary metastases in vivo, using corresponding assays and models. Addtionally, we revealed that celastrol inhibited the integrin-mediated Mice melanoma cell B16F10 and human lung cancer cell D cell-ECM adhesion and spreading partially via p38 MAPK Pathway, which also contributed to its antimetastatic effect.
Celastrol inhibited D and B16F10 cells adhesion to fibronectin in a dose-dependent manner. On the contrary, the cell adhesion to poly-l-lysine PLLan event did not engage with integrin, was not affected upon celastrol treatment.
The formation of focal adhesions was also disrupted by celastrol.
In understanding the underlying mechanisms, we found that celastrol activated p38 mitogen-activated protein kinase MAPK by phosphorylation prior to the decrement of phosphorylated FAK, and was independent on the presence of fibronectin. Furthmore, focal adhesion-dependent cell migration and invasion were both inhibited by treatment with celastrol.
Collectivly, these data not only demonstrates that celastrol exerts potent anti-metastasis activity both in vitro and in vivo, but also provides new evidences for the critical roles of p38 MAPK in the regulation of integrin function and cell adhesion.Tree Ring Dating of the Archaeological Sites in the Chaco Canyon Region, New Mexico, Southwest Parks and Monuments Association Technical Series, 6(2), .
