HOTAIR: an oncogenic long non-coding RNA in different cancers

Area of Science:

• Molecular Biology
• Genetics
• Oncology

Background:

• Long non-coding RNAs (lncRNAs) are key regulators of gene expression.
• lncRNAs play significant roles in the development of various human diseases, particularly cancer.
• HOTAIR is an lncRNA implicated as an oncogenic molecule in multiple cancer types.

Purpose of the Study:

• To review the molecular functions and regulation of HOTAIR.
• To elucidate the role of HOTAIR in the pathogenesis of different cancers.
• To highlight HOTAIR as a potential diagnostic and therapeutic biomarker.

Main Methods:

• Literature review of studies on HOTAIR function and cancer association.
• Analysis of HOTAIR's interaction with Polycomb Repressive Complex 2 (PRC2).
• Examination of HOTAIR's role in epigenetic gene regulation.

Main Results:

• HOTAIR is involved in epigenetic regulation and cellular pathways.
• Elevated HOTAIR expression is observed in breast, gastric, colorectal, and cervical cancers.
• HOTAIR's oncogenic activity is confirmed across various cancer cell types.

Conclusions:

• HOTAIR is a crucial oncogenic lncRNA with significant roles in cancer.
• HOTAIR expression levels can serve as valuable biomarkers for cancer diagnosis and therapy.
• Further research into HOTAIR's mechanisms may yield novel therapeutic strategies.
