Long noncoding RNA HOXA11-AS promotes gastric cancer cell proliferation and invasion via SRSF1 and functions as a biomarker in gastric cancer.
CONCLUSION: HOXA11-AS promotes GC cell proliferation and invasion via SRSF1 and may function as a promising marker in GC. PMID: 31235999 [PubMed - in process]
Gastric cancer remains one of the most common causes of cancer deaths worldwide. The best current option for reducing gastric cancer deaths is Helicobacter pylori eradication combined with risk assessment and surveillance programs for those deemed to be at high risk for gastric cancer so as to identify lesions at a stage amenable to curative therapy. In this issue, Nam et al1 report a retrospective study of Helicobacter pylori eradication on gastric cancer incidence among 10,328 Korean adults undergoing health checkups including an H pylori test-and-treat program.
Gastric cancer remains one of the most common cancers worldwide and is the third leading cause of cancer-related mortality, trailing only lung and colon cancer.1 Given its historically low survival rates, early detection and resection is the most effective strategy to improve prognosis. Endoscopic submucosal dissection (ESD), a technique developed in Japan, enables en bloc resection of early gastric cancer (EGC) and can be curative for selected lesions, depending on the histologic features, size, and tumor depth.
We have read with great interest the study by Januszewicz et al1 describing the concept of endoscopist biopsy rate (EBR) as a potential quality indicator for routine diagnostic outpatient EGD. The authors found a significant variability in EBR among 26 endoscopists and an association between higher EBR, a higher detection of gastric precancerous conditions, and a lower risk of missed gastric cancers.1

In this study, Cosmic database revealed that the expression level of TWA1 ranks in the top 20 of overexpressed genes in GC. Further bioinformatic analysis revealed that the expression level of TWA1 is not in connection with the infection status of HP or EB. IHC and IF showed that TWA1 protein was present in both the cytoplasm and nucleus, but mainly in the cytoplasm. The high expression level of TWA1 was also related to tumor size, depth of invasion, lymph node metastasis, TNM stage, cancerous node and vascular invasion. Furthermore, higher TWA1 expression is also associated with shorter PFS and OS in GC. The univariate an...
Gastric cancer (GC), one of the most common malignant tumors and the second most common leading cause of cancer-related death worldwide, is a biologically heterogeneous disease accompanied by various genetic and epigenetic alterations. However, the molecular mechanisms underlying this disease are complex and not completely understood. Increasing studies have shown that aberrant microRNA (miRNA) expression is associated with GC tumorigenesis and growth. MiR-1297 has been confirmed to be a cancer suppressor in diverse tumors in humans. However, to date, the function and mechanism of miR-1297 in GC have not been determined. H...
Conclusions: TAM are well preserved and can be studied in TSC of gastric cancer. Iron deprivation significantly increased tumor cell apoptosis. PMID: 31413815 [PubMed]
