• TSGH8301 human bladder cancer cells

Matrix metalloproteinases (MMPs) play an important role in the invasion, metastasis and angiogenesis of cancer cells. Many agents have been shown to inhibit the cancer cell migration and invasion by suppression of MMPs. 2-(3-Methoxyphenyl)-6,7-methylenedioxoquinolin-4-one (MMEQ) is a derivative compound synthesized from quinolin and the purpose of this study is to determine whether or not cell migration would be reduced in human bladder cancer TSGH8301 cells after MMEQ treatment. Wound healing assay and boyden chamber assay were used in cell migration and invasion determinations. Cell migration and invasion inhibited by MMEQ exerted an inhibitory effect on the sevenless homolog-1 (SOS-1), protein kinase c (PKC), extracellular signal-regulated kinase (ERK) and Rho A for causing the inhibitions of MMP-2 and -9, and then followed by the inhibitions of invasion and migration. MMEQ also affected FAK, PI3K or inhibited growth factor receptor-bound protein 2 (GRB2), nuclear factor kappaB (NF-kappa B), inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) for cell proliferation inhibition. Therefore, MMEQ may serve as a drug in the prevention of tumor metastasis of bladder cancer in the future.
