LINC00511-dependent inhibition of IL-24 contributes to the oncogenic role of HNF4α in colorectal cancer.

Hepatocyte nuclear factor 4 α (HNF4α) is an important transcription factor that acts as a pro-proliferative mediator during tumorigenesis, yet its function in colorectal cancer (CRC) remain unclear. Hence, this study aims to explore roles that HNF4α plays in the CRC development. RNA quantification analysis was conducted to characterize the expression pattern of long intergenic noncoding RNA 00511 (LINC00511)/HNF4α/IL-24 in CRC tissues and cell lines.

Comparison between laparoscopic and endoscopic resections for gastric submucosal tumors.

Background/aims: Open resection/laparoscopic resection (LR) is the traditional treatment of gastric submucosal tumor (G-SMT). The endoscopic resection (ER) technology provides good results for G-SMT treatment but lacks sufficient evidence-based evidence. This retrospective study aimed to compare the clinical efficacy of ER [endoscopic submucosal dissection (ESD), endoscopic submucosal excavation (ESE), and endoscopic full-thickness resection (EFR)] and LR [laparoscopic wedge resection (LWR) and laparoscopic subtotal gastrectomy (LSG)] for G-SMT.

The lncRNA ZEB1-AS1 sponges miR-181a-5p to promote colorectal cancer cell proliferation by regulating Wnt/β-catenin signaling.

Long noncoding RNAs (lncRNAs) are important regulators of the biological functions and underlying molecular mechanisms of colorectal cancer (CRC). However, the role of the lncRNA ZEB1-AS1 in CRC is not thoroughly understood. In this study, we found that ZEB1-AS1 was markedly upregulated in CRC.

Expression of microRNA-328 Functions as a Biomarker for Recurrence of Early Gastric Cancer (EGC) After Endoscopic Submucosal Dissection (ESD) by Modulating CD44.

BACKGROUND This study investigated the molecular mechanism of the effect of CD44 on the recurrence of EGC after ESD, including the potential regulator and signaling pathways of CD44. MATERIAL AND METHODS We searched the miRNA online database (www.mirdb.
