The effect of HO-1 overexpression on microRNA transcriptome in NCI-H292 lung cancer cells

ABSTRACT: The aim was to determine the effect of heme oxygenase-1 (HO-1) overexpression on microRNA transcriptome in human non-small cell lung carcinoma cell line (NCI-H292). Since the cells of different HO-1 genotypes were used (cells are after retroviral transduction with empty vector with normal level of HO-1 or retroviral transduction with vector harboring HO-1), it is possible get the comprehensive answer which microRNAs are regulated by HO-1. Confluent NCI-H292 cells that contain EV-ctrl or overexpressing HO-1. Pool of reference cells are cells untreated and treated with 10 ng/ml TNF-M-NM-1 for 6 hours before RNA isolation. The samples are biological triplicates - three independent experiments were performed at different time points for all cell lines. Total number of the presented samples is 6.

<h4>Aims</h4>Heme oxygenase-1 (HO-1, HMOX1) can prevent tumor initiation; while in various tumors, it has been demonstrated to promote growth, angiogenesis, and metastasis. Here, we investigated whether HMOX1 can modulate microRNAs (miRNAs) and regulate human non-small cell lung carcinoma (NSCLC) development.<h4>Results</h4>Stable HMOX1 overexpression in NSCLC NCI-H292 cells up-regulated tumor-suppressive miRNAs, whereas it significantly diminished the expression of oncomirs and angiomirs.
