Tectorigenin inhibits osteosarcoma cell migration through downregulation of matrix metalloproteinases in vitro

چکیده
Tectorigenin (Tec) is an effective component of the traditional Chinese medicine Belamcanda chinensis, which has been reported to exert beneficial effects in various types of cancer. However, the activity and mechanism of Tec in osteosarcoma (OS) have not been investigated to date. The aim of the present study was to examine the inhibitory effect of Tec on OS and its underlying mechanism of action. OS cells (Saos2 and U2OS) were treated with various concentrations of Tec for 24, 48, and 72 h. Cell proliferation was evaluated using an CCK-8 assay. Cell migration and invasion ability were measured using the Transwell assay. The expressions of MMP1, MMP2, MMP9, and cleaved caspase3 were measured using real-time PCR and/or western blot analysis. We found that Tec inhibited the proliferation of OS cells (Saos2 and U2OS) in a dose-dependent and time-dependent manner. In addition, Tec significantly inhibited migration and invasion in OS cells (P<0.05). Tec upregulated the expression of cleaved caspase3, while downregulating the expression of MMP1, MMP2, and MMP9. Taken together, the present study provided fundamental evidence for the application of Tec in chemotherapy against OS.

shRNA-mediated downregulation of α-N-Acetylgalactosaminidase inhibits migration and invasion of cancer cell lines
Objective(s): Extracellular matrix (ECM) is composed of many kinds of glycoproteins containing glycosaminoglycans (GAGs) moiety. The research was conducted based on the N-Acetylgalactosamine (GalNAc) degradation of ECM components by α-N-acetylgalactosaminidase (Nagalase) which facilitates migration and invasion of cancer cells. This study aims to investigate the effects of Naga-shRNA downregula...

Introduction: Glioblastoma is an aggressive malignancy of human brain with poorly understood pathogenesis. Voltage-gated potassium (Kv) channels and Matrix metalloproteinases (MMPs) are highly expressed in malignant tumors and involved in the progression and metastasis of glioblastoma. The purpose of this study was to determine whether a voltage-dependent potassium channel blocker could modulat...
متن کاملDiallyl trisulfide inhibits proliferation, invasion and angiogenesis of osteosarcoma cells by switching on suppressor microRNAs and inactivating of Notch-1 signaling.
Notch signaling pathway plays critical roles in human cancers, including osteosarcoma, suggesting that the discovery of specific agents targeting Notch would be extremely valuable for osteosarcoma. Our previous studies have shown that diallyl trisulfide (DATS) inhibits proliferation of osteosarcoma cells by triggering cell cycle arrest and apoptosis in vitro. However, the underlying mechanism i...

In the present study, the effect of fatty acid synthase (FASN) inhibition on cell invasion and migration in vitro was investigated. A recombinant plasmid containing a microRNA targeting the FASN gene was used to inhibit FASN expression in U2‑OS cells. Cell migration and invasion were investigated using wound healing and Transwell invasion assays. We found that cell invasion and migration were s...

Osteosarcoma is a common, high-risk primary bone malignancy that mostly affects the younger population. There has been no marked improvement in the clinical outcomes of osteosarcoma patients to date, and cancer recurrence and metastasis are common in high-grade osteosarcoma. Therefore, identifying new biomarkers and novel therapeutic targets is crucial for improving the prognosis of osteosarcom...
