Vacuolar ATPase (V-ATPase), widespread in eukaryotic cells, is extensively expressed in many highly metastatic tumors, of which the V-ATPase c subunit ATP6V0C is particularly associated with the invasion and metastasis of cancer. ATP6V0C was directly found to interact with LASS2/TMSG1 which is a new tumor metastasis inhibitory gene identified by our laboratory in 1999. In order to study the role of ATP6V0C, we generated small interference RNA (siRNA) targeting ATP6V0C and investigated its function on the invasion of human prostate cancer cell line PC-3M-1E8 with high metastatic potential and its interplay with LASS2/TMSG1...

Oral cancer is a solid malignant tumor that is prone to occur following hypoxia. There are no clear studies showing a link between hypoxia and oral carcinogenesis. Carbonic anhydrase IX (CAIX), which is a hypoxia-induced transmembrane protein, is highly expressed in various types of human cancer. However, the effects of CAIX on the metastasis of human oral cancer cells and the underlying molecular mechanisms have not been clarified. In this study, we observed that CAIX overexpression increased the migratory and invasive abilities of SCC-9 and SAS cells...

PURPOSE: Oral squamous cell carcinoma (OSCC)-related deaths mainly result from invasion of the tumor cells into local cervical lymph nodes. It has been reported that progressive basement membrane loss promotes the metastatic and invasive capacities of OSCCs. Matrix metalloproteinase-9 (MMP-9) is known to play a central role in tumor progression and invasion. However, the role of MMP-9 in OSCC invasion has so far remained paradoxical and little is known about its regulation. Here, we aimed to assess MMP-9 expression regulation and its activation by glycogen synthase kinase-3β during human OSCC progression and invasion...

A new class of polyamine analogues modified by alkylation at the terminal of the polyamine chain has been synthesized and their structures were determined by (1)H NMR, (13)C NMR, ESI-MS and elemental analysis. As the representative compound, 3f displayed a broad spectrum of anti-cancer effects by MTT assays. Tumor xenograft model and pulmonary metastasis model showed that compound 3f significantly suppressed tumor growth and metastasis in vivo, which was more stronger than the reference drug amonafide. Molecular mechanisms indicated that compound 3f exhibited antiproliferative activities and induced the generation of reactive oxygen species (ROS), which resulted in the occurrence of autophagy...

Previously, we showed that the herbal extract EYK (Epimedium koreanum Nakai) can regulate the immune response. Other studies showed that EYK has beneficial effects in human lung cancer, angiogenesis and Alzheimer's disease (AD). However, it remains unknown whether EYK can affect cancer cell migration and invasion in human brain cancer cell lines. In the present study, we found that pre- or post-treatment with EYK inhibited phorbol 12-myristate 13-acetate (PMA)-induced cancer cell migration and invasion in A172 cells, but not in U373MG or T98G cells...
