Long noncoding RNA LINC01606 protects colon cancer cells from ferroptotic cell death and promotes stemness by SCD1-Wnt/β-catenin-TFE3 feedback loop signalling.

ABSTRACT:

Background

Ferroptosis is principally caused by iron catalytic activity and intracellular lipid peroxidation. Long noncoding RNAs (lncRNAs) play crucial roles in tumorigenesis. However, the potential interplay between lncRNA LINC01606 and ferroptosis in colon cancer remains elusive.

Methods

The expression level of LNC01606 in colon cancer tissue was detected by quantitative real-time polymerase chain reaction. The functional role of LNC01606 was investigated by gain- and loss-of-function assays both in vitro and in vivo. The LINC01606-SCD1-Wnt/β-catenin-TFE3 axis were screened and validated by DNA/RNA pull down, gas chromatography-mass spectrometry, RNA immunoprecipitation and dual-luciferase reporter.

Results

The expression of lncRNA LINC01606 was frequently upregula
