Abstract

Background: Long non-coding RNAs (lncRNAs) are essential regulators in colorectal cancer (CRC) progression. This work aimed to delve into the characteristics of lncRNA in CRC.

Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) was adopted to examine , high-mobility group box-1 (HMGB1) mRNA expressions in CRC tissues and cell lines. Functionally, cell counting kit-8 (CCK-8) and 5-ethynyl-2-deoxyuridine (EdU) incorporation assays were employed to examine cell proliferation; wound healing assay was utilized to detect cell migration; and flow cytometry was used to detect the cell apoptosis. Luciferase reporter assay, RNA immunoprecipitation assay and Western blot were conducted to detect the regulatory relationships among and HMGB1.

Results: and HMGB1 mRNA expressions were observably elevated in CRC tissues and cell lines. Knocking down could significantly inhibit cell proliferation and migration, and promote apoptosis of CRC cells. could serve as a competitive endogenous RNA, and up-regulate HMGB1 expression by adsorbing .

Conclusion: can expedite CRC cell proliferation and migration, and inhibit apoptosis through /HMGB1 axis.
