Oxymatrine attenuates oxidized low ‑density lipoprotein‑induced HUVEC injury by inhibiting NLRP3 inflammasome‑mediated pyroptosis via the activation of the SIRT1/Nrf2 signaling pathway
Int J Mol Med. 2021 Oct;48(4):187. doi: 10.3892/ijmm.2021.5020. Epub 2021 Aug 9.ABSTRACTOxymatrine, a quinolizidine alkaloid isolated from the traditional Chinese herb Sophora flavescens Aiton, has been demonstrated to exert anti‑inflammatory and atherosclerotic effects, but the molecular mechanism has yet to be elucidated. Accumulating evidence indicates an important role of NLR family pyrin domain containing 3 (NLRP3) inflammasome‑mediated pyroptosis in the pathogenesis of atherosclerosis. The present study was undertaken to investigate whether oxymatrine attenuates oxidized low‑density lipoprotein (ox‑LDL)‑ind...

Astragalus polysaccharide induces the apoptosis of human hepatocellular carcinoma cells by decreasing the expression of Notch1.
Abstract Hepatocellular carcinoma (HCC) is the third most frequent cause of cancer death worldwide. Astragalus polysaccharide (APS), the primary active component extracted from a traditional Chinese medicinal herb Astragalus membranaceus, has been proved to exert a marked inhibitory effect on a number of types of human solid tumors. In the present study, we aimed to examine the effects of APS on the survival of the HCC cell line H22 and to elucidate the underlying regulatory mechanisms responsible for these effects. Our results revealed that the mRNA and protein expression of Notch1 was significantly upregulate...

Purified vitexin compound 1 inhibits growth and angiogenesis through activation of FOXO3a by inactivation of Akt in hepatocellular carcinoma.
Abstract Vitexins, isolated from the seeds of the Chinese herb Vitex negundo, is known to exert antitumor activity in cancer xenograft models and cell lines. The aim of the current study was to examine whether the Akt/forkhead box protein O3a (FOXO3a) pathway mediates the biological effects of purified vitexin compound 1 (VB-1) in hepatocellular carcinoma (HCC) cells. The effect of VB-1 on the viability of the HCC cell lines HepG2, Hep3B, Huh-7 and the human embryonic liver cells L-02 was investigated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Growth inhibition was assess...

Extracts of Koelreuteria henryi Dummer induce apoptosis and autophagy by inhibiting dihydrodiol dehydrogenase, thus enhancing anticancer effects.
Abstract Dihydrodiol dehydrogenase (DDH) is frequently detected in cancer cells, and its overexpression correlates with drug resistance, the downregulation of DNA repair mechanisms, increased frequency of tumor recurrence, cancer cell metastasis and poor prognosis. The silencing of DDH expression using siRNA, on the other hand, reduces drug resistance and cancer cell mobility. These data suggest that DDH may be an oncogene-related protein. However, no specific DDH inhibitor has been identified to date. Thus, in this study, we used DDH as a target enzyme in a live-cell enzyme-linked immunosorbent assay to screen Ch...

Salidroside reduces cold-induced mucin production by inhibiting TRPM8 activation.
Abstract Salidroside is an effective component of the traditional Chinese herb, Rhodiola rosea, that is known to have the ability to protect individuals from cold attacks. In the present study, we investigated the effects of salidroside on respiratory epithelial cells exposed to cold temperatures. We wished to determine whether salidroside exerts any effect on cold-induced mucin (MUC) production and the possible mechanisms involved in this process. We incubated HBE16 cells with salidroside, exposed them to a cold stimulus (18˚C), and assayed the following endpoints: MUC production (the expression of MUC5AC), conc...
