Antitumor effects of matrine on cancer stem like cells isolated from the human liver cancer SMMC‑7721 cell line

Abstract

Abstract. The existence of cancer stem cells (CSCs) or cancer stem-like cells (CSLCs) is regarded as the cause of tumor formation and recurrence. Matrine has been reported to exhibit antitumor effects in cancer cells. In the present study, a preliminary study was performed on the mechanisms of matrine on hepatocellular carcinoma (HCC) stem-like cells. The HCC SMMC-7721 cell line was cultured in tumor stem cell-specific medium to form spheres, and different concentrations (1, 2 and 5 mg/kg) of cisplatin were then used in order to purify the most drug-resistant cells, which were used as CSLCs. An MTT assay was performed to detect the inhibitory effects of matrine against CSLC proliferation. Quantitative polymerase chain reaction (qPCR) and western blot analysis were used to detect changes in cell adhesion regulating gene (CAR), E-cadherin, laminin and fibronectin. As a result, using tryptose sulfite cycloserine medium culture and cisplatin-resistance screening, CSLCs were successfully isolated from the SMMC-7721 cell line. Matrine inhibited the proliferation of CSLCs in vitro. The results of qPCR and western blot analysis demonstrated that matrine upregulated the expression of CAR, E-cadherin, laminin and fibronectin in CSLCs compared with the control treatment. A certain concentration of matrine exhibited antitumor effects on HCC stem like cells.

Transcriptome analysis of phycocyanin inhibitory effects on SKOV-3 cell proliferation

“…Current researches demonstrated that PC had magnificent perspective in cancer treatment both in vitro and in vivo. Wang Y (Wang et al, 2009) discovered that phycocyanin from Porphyrayezoensis could kill human liver cancer cell SMMC-7721 in vitro. Li B reported that phycocyanin could remarkably prohibit the growth and development of human lung cancer A549 cells on a time-and dose-dependent manner.…”

Extraction, Separation, Antitumor Effect, and Mechanism of Alkaloids in Sophora alopecuroides: A Review

“…Total alkaloids present in S. alopecuroides have been shown to impede growth; treatment with 8.75 mg/mL of total alkaloids of S. alopecuroides caused cell death in >50% of HeLa cells, and the cell death rate increased with longer incubation. Additionally, several active ingredients of S. alopecuroides, including aloperine [19], cytosine [20,21] matrine [22][23][24][25], oxymatrine [26][27][28], sophoridine [29,30], oxysophoridine [31], and sophocarpine [32], are also known to impede tumor cell growth.…”

Research Progress on the Effect of Traditional Chinese Medicine Monomers and Derived Compounds on Liver Cancer Stem Cells

“…It inhibited the proliferation of LCSCs in a dose-dependent manner, and upregulated the levels of CAR, laminin, E-cadherin as well as fibronectin in LCSCs which led to the reduction of cell adhesion and the increase of cell apoptosis. All in all, matrine may inhibit LCSCs by regulating CAR signal transduction [50].…”
