MiR-1976 affects lung squamous cell carcinoma development by targeting NCAPH

Area of Science:

• Oncology
• Molecular Biology
• Biomarker Discovery

Background:

• Lung squamous cell carcinoma (LUSC) is a major lung cancer subtype.
• Non-SMC condensin I complex subunit H (NCAPH) is a potential biomarker in malignancies, but its role in LUSC is unclear.

Purpose of the Study:

• To investigate the effect of NCAPH on LUSC progression.
• To identify upstream microRNAs (miRNAs) regulating NCAPH function in LUSC.

Main Methods:

• Utilized TCGA database for miRNA and mRNA expression profiles and clinical data.
• Employed qRT-PCR, western blot, CCK-8, colony formation, Transwell assays, and flow cytometry.
• Bioinformatic prediction and dual-luciferase reporter assays confirmed miRNA-target interactions.

Main Results:

• NCAPH expression was significantly higher in LUSC tissues, while miR-1976 expression was significantly lower.
• miR-1976 directly targets NCAPH.
• Reduced NCAPH expression inhibited LUSC cell proliferation, migration, and invasion, and promoted apoptosis.

Conclusions:

• NCAPH is a potential oncogenic biomarker in LUSC.
• miR-1976 regulates NCAPH, impacting LUSC cell behavior.
• The miR-1976/NCAPH axis influences LUSC progression.
