HOX cluster-embedded antisense long non-coding RNAs in lung cancer

Area of Science:

• Genetics
• Molecular Biology
• Oncology

Background:

• Homeobox (HOX) genes are critical in development and cancer.
• HOX gene clusters contain non-protein-coding RNAs, including HOX-lncRNAs.
• HOX-lncRNAs like HOTTIP and HOTAIR regulate adjacent genes.

Purpose of the Study:

• To review the functions of HOX-lncRNAs in lung cancer.
• To highlight the role of HOX-lncRNAs in tumorigenesis and cancer progression.
• To emphasize the need for further investigation into HOX-lncRNA functions in cancer.

Main Methods:

• Literature review of studies on HOX-lncRNAs and lung cancer.
• Analysis of dysregulated HOX-lncRNAs in lung cancer.
• Examination of molecular mechanisms by which HOX-lncRNAs affect lung cancer cells.

Main Results:

• Several HOX-lncRNAs (HOTTIP, HOXA11-AS, HOTAIRM1, HOXA-AS3, HOXA10-AS, HOTAIR, HAGLR) are dysregulated in lung cancer.
• Expression levels of these HOX-lncRNAs correlate with clinical features.
• HOX-lncRNAs influence lung cancer cell proliferation, invasion, migration, and chemo-resistance.

Conclusions:

• HOX-lncRNAs play significant roles in lung cancer development and progression.
• Dysregulation of HOX-lncRNAs is linked to clinical outcomes in lung cancer patients.
• Further research on HOX-lncRNAs is essential for understanding and potentially treating lung cancer.
