ABSTRACT Vitamin C has re-emerged as a promising anticancer agent. This study attempts to analyze the differential gene expression of profiles GSE11919 to look for some clues, and the most significant cell cycle pathway caused by vitamin C was identified by integrated bioinformatics analysis. Inspired by this, we investigated the effect of vitamin C treatment on gastric carcinoma cells by detection of cell cycle, apoptosis, and autophagy. Vitamin C significantly elevated the percentage of cells at G0/G1 phase, whereas the percentage of S phase cells was decreased. Meanwhile, vitamin C treatment resulted in downregulation of cell cycle-related protein Cyclin D1. We deduced that the downregulation of Cyclin D1 by vitamin C accompanied by significantly increased 5′AMP-activated protein kinase and induced autophagy in MKN45 cells. These results suggest that vitamin C has the antiproliferation effect on gastric carcinoma cells via the regulation of cell cycle and autophagy by Cyclin D1.

Increasing evidence suggests that miR-194 is down-regulated in esophageal squamous cell carcinoma tumor tissue. However, the role and underlying mechanism of miR-194 in esophageal squamous cell carcinoma have not been well defined. We used DIANA, TargetScan and miRanda to perform target prediction analysis and found KDM5B is a potential target of miR-194. Based on these findings, we speculated that miR-194 might play a role in esophageal squamous cell carcinoma development and progression by regulation the expression of KDM5B. We detected the expression of miR-194 and KDM5B by quantitative real-time reverse transcription PCR (qRT-PCR) and Western blot assays, respectively, and found down-regulation of miR-194 and up-regulation of KDM5B existed in esophageal squamous cell carcinoma cell lines. By detecting proliferation, invasion and apoptosis of TE6 and TE14 cells transfected with miR-194 mimics or mimic control, miR-194 was found to inhibit proliferation and invasion and promote apoptosis of esophageal squamous cell carcinoma cells. miR-194 was further verified to regulate proliferation, apoptosis and invasion of esophageal squamous cell carcinoma cells by directly targeting KDM5B. Furthermore, animal studies were performed and showed that overexpression of miR-194 inhibited the growth of esophageal squamous cell carcinoma tumors in vivo. These results confirmed our speculation that miR-194 targets KDM5B to inhibit esophageal squamous cell carcinoma development and progression. These findings offer new clues for esophageal squamous cell carcinoma development and progression and novel potential therapeutic targets for esophageal squamous cell carcinoma.
