DLC1 inhibits colon adenocarcinoma cell migration by promoting secretion of the neurotrophic factor MANF.

DLC1 (deleted in liver cancer-1) is downregulated or deleted in colorectal cancer (CRC) tissues and functions as a potent tumor suppressor, but the underlying molecular mechanism remains elusive. We found that the conditioned medium (CM) collected from DLC1-overexpressed SW1116 cells inhibited the migration of colon adenocarcinoma cells HCT116 and SW1116, but had no effect on proliferation, which suggested DLC1-mediated secretory components containing a specific inhibitor for colon adenocarcinoma cell migration. Analysis by mass spectrometry identified mesencephalic astrocyte-derived neurotrophic factor (MANF) as a candidate.

MicroRNA-1254 inhibits the migration of colon adenocarcinoma cells by targeting PSMD10.

Objective: MicroRNA-1254 (miR-1254) has not been studied in colorectal cancer (CRC) to date. This study aimed to investigate the inhibitory mechanism of miR-1254 in CRC tumorigenesis.

Methods: MiR-1254 expression was examined using real-time polymerase chain reaction in CRC and adjacent non-tumorous tissues.

Role of B7-H4 siRNA in Proliferation, Migration, and Invasion of LOVO Colorectal Carcinoma Cell Line.

Objectives: Colorectal cancer is one of the most common malignancies. Recent studies investigated that B7-H4 is highly expressed in various cancers. We aimed at exploring the effect of B7-H4 siRNA on proliferation, invasion, and migration of LOVO cells which expressed B7-H4 notably.

Role of insular cortex in visceral hypersensitivity model in rats subjected to chronic stress.

Abnormal processing of visceral sensation at the level of the central nervous system has been proven to be important in the pathophysiologic mechanisms of stress related functional gastrointestinal disorders. However, the specific mechanism is still not clear. The insular cortex (IC) was considered as one important visceral sensory area.

p73 Overexpression and angiogenesis in human colorectal carcinoma.

Background: Solid tumors requires neovascularization for growth and metastasis. Angiogenesis depends on the local balance between positive and negative effectors, the production of which can be regulated by oncogenes and tumor suppressor genes. The aim of this study was to investigate expression of p73, a gene homologous to the tumor suppressor gene p53, in colorectal cancer and its relationship to angiogenesis.
