Long Non-Coding RNA HOTAIR Promotes Carcinogenesis and Invasion of Gastric Adenocarcinoma

Strategic Insights -

Fresh data on the role of long non-coding RNA HOTAIR in gastric adenocarcinoma have been presented in a new report. Research from Yonsei University in Seoul, South Korea, has found that HOTAIR promotes carcinogenesis and invasion of gastric adenocarcinoma by inhibiting apoptosis and promoting invasiveness. The study highlights the complex mechanism of carcinogenesis in gastric cancer, which is a major cause of cancer death worldwide.

Key Takeaways:

  • HOTAIR was found to be significantly elevated in gastric cancer cell lines and tissues compared to normal control, suggesting its role in carcinogenesis.
  • Downregulation of HOTAIR using siRNAs reduced viability in MKN 28, MKN 74, and KATO III cells, but not in AGS cells.
  • HOTAIR induced apoptosis in KATO III cells and reduced invasiveness and migration in various gastric cancer cell lines.
  • Lymphovascular invasion and lymph node metastasis were more common in the high level of HOTAIR group, indicating its clinical significance.
  • The expression of HOTAIR was found to be associated with the progression of gastric adenocarcinoma.
  • The study suggests that HOTAIR could be a potential target for the treatment of gastric cancer.
