Malignant melanoma is a melanocytic tumor with a high potential of invasion and metastasis. Curcumin is extracted from Curcuma longa L.; curcumin has anti-tumor efficacy in multiple systemic malignancies. Here, we investigated the effect of curcumin on A375 human melanoma cells. A375 cells were cultivated, passaged, and treated with different concentrations of curcumin. We observed the cellular morphology and determined the migration, invasion, proliferation, and apoptosis of A375 cells in vitro.
Pancreatic ductal adenocarcinoma (PDAC) is characterized by a poor prognosis and high mortality rate. In this study, we investigated the expression of Rab23 in non-tumor pancreatic tissues and PDACs via immunohistochemistry. Rab23 was found in 39 of 58 (67.2%) and in 11 of 30 (36.7%) of the PDAC and non-tumor pancreatic tissue samples (P = 0.0073), respectively. There were significant correlations between Rab23 expression and unfavorable variables, including cancer differentiation level (P = 0.0089), lymph nodal (P = 0.0099), and distant metastases (P = 0.0173).
The Gax gene has been implicated in a variety of cell-developmental and biological processes, and aberrant Gax expression is linked to many diseases. In this study, to provide important insights for Gax-based gene therapy in vein graft restenosis and its anti-restenotic mechanism, we used rabbit vascular smooth muscle cells (VSMCs) to investigate the effects of Gax overexpression on proliferation, migration, cell cycle, and apoptosis in a serum-stimulated culture.
Nong-Han Lake, Thailand, sustains the whisker sheatfish (Micronema bleekeri Günther, 1864), which is a rare species of freshwater catfish. Wild-caught whisker sheatfish has been intensively harvested to meet market demand; yet, genetic information about this species remains unknown. To assist with the in situ conservation of whisker sheatfish populations in Nong-Han Lake, 35 and 34 individuals from the middle (MN) and lower (LN) areas of the lake, respectively, were studied using 7 microsatellite loci.
Breast cancer is a common cancer in women, with a highly variable course, from inoffensive to lethal. To find a more effective strategy for its treatment, sodium valproate has been tested as an anti-cancer drug; it is the only clinically available histone deacetylase inhibitor. However, data about the effects of sodium valproate on breast cancer are insufficient in both animals and humans; studies have yielded conflicting conclusions. In particular, little is known about the association between expression of the metastasis suppressor Nm23H1 gene and breast cancer.
