Abstract

BACKGROUND: Although the oncogenic roles of multiple copies in T-cell malignancy 1 (MCT-1) have been revealed in multiple cancers, its effects on non-small cell lung cancer (NSCLC) progression are still uncertain. This study aimed to reveal the effects of MCT-1 on the stem cell-like traits of NSCLC cells.

MATERIAL AND METHODS: Western blot, real-time quantitative polymerase chain reaction (RT-qPCR), spheroid forming ability, and ALDH1 (aldehyde dehydrogenase 1) activity analysis were carried out to examine the effects of MCT-1/micrRNa-34 (miR-34a)/interleukin-6 (IL-6) on the stem cell-like characteristics of lung cancer cells.

RESULTS: MCT-1 knockdown reduced the spheroid forming ability, characterized as the decreased spheroid size and number. Additionally, MCT-1 knockdown decreased the expression of the NSCLC stemness markers and the activity of ALDH1. Moreover, MCT-1 knockdown decreased IL-6 secretion that promotes NSCLC cell stemness. Furthermore, MCT-1 knockdown increased the level of miR-34a, which attenuated the stemness of NSCLC cells through targeting IL-6R (IL-6 receptor) expression.

CONCLUSIONS: These results suggest MCT-1/miR-34a/IL-6/IL-6R axis is responsible for MCT-1-mediated effects on NSCLC cell stemness.
