Ursonic acid is a pentacyclic triterpenoid compound that can be extracted from Ziziphus jujuba Mill., a traditional medicine. Matrix metalloproteinases (MMPs) are involved in cancer metastasis and skin aging. Regulation of various MMPs is closely associated with mitogen-activated protein kinases (MAPKs), including ERK, p38, and JNK MAPKs. In this study, we investigated the possibility of ursonic acid as an anti-cancer/anti-skin aging agent targeting MMPs. Cytotoxic effects of ursonic acid were analyzed by cell counting kit-8 (CCK-8) assay. Invasive abilities of ursonic acid-treated A549 and H1299 non-small cell lung cancer (NSCLC) cells were tested with Boyden chamber assay. Effects of ursonic acid on MMPs were analyzed by zymography assays and quantitative real time polymerase chain reaction (qRT-PCR). We also conducted flow cytometry and western blot analysis to elucidate the mechanisms of MMP regulation by ursonic acid. Our results revealed that ursonic acid inhibited transcriptional expression of gelatinases (MMP-2 and MMP-9) via inhibition of ERK and CREB signaling pathways in NSCLC cells. Moreover, ursonic acid reduced mRNA levels of collagenase (MMP-1) via suppression of ERK and c-Fos signaling pathways in HaCaT keratinocytes. These results suggest that ursonic acid could be a potential candidate for development of an effective novel anti-cancer and anti-wrinkle agent.

熊果酸通过ERK信号通路对基质金属蛋白酶产生抑制作用。

熊果酸是一种五环三萜类化合物,可以从传统药物枣树磨中提取。基质金属蛋白酶(MMP)与癌症转移和皮肤衰老有关。各种MMP的调节与包括ERK,p38和JNK MAPK在内的丝裂原活化蛋白激酶(MAPK)密切相关。在这项研究中,我们调查了熊果酸作为针对MMPs的抗癌/抗皮肤衰老剂的可能性。熊果酸的细胞毒性作用通过细胞计数试剂盒8(CCK-8)分析进行了分析。用博登室测定法检测了熊果酸处理过的A549和H1299非小细胞肺癌(NSCLC)细胞的侵袭能力。通过酶谱分析和定量实时聚合酶链反应(qRT-PCR)分析了熊果酸对MMP的影响。我们还进行了流式细胞术和蛋白质印迹分析,以阐明熊果酸对MMP的调控机制。我们的研究结果表明,熊果酸可通过抑制NSCLC细胞中的ERK和CREB信号通路来抑制明胶酶(MMP-2和MMP-9)的转录表达。此外,熊果酸通过抑制HaCaT角质形成细胞中的ERK和c-Fos信号通路降低了胶原酶(MMP-1)的mRNA水平。这些结果表明,熊果酸可能是开发有效的新型抗癌和抗皱剂的潜在候选者。熊果酸通过抑制HaCaT角质形成细胞中的ERK和c-Fos信号通路降低了胶原酶(MMP-1)的mRNA水平。这些结果表明,熊果酸可能是开发有效的新型抗癌和抗皱剂的潜在候选者。熊果酸通过抑制HaCaT角质形成细胞中的ERK和c-Fos信号通路降低了胶原酶(MMP-1)的mRNA水平。这些结果表明,熊果酸可能是开发有效的新型抗癌和抗皱剂的潜在候选者。
