Molecular classification

01

Overview

C8orf34 antisense RNA 1 (C8orf34-AS1) is a long non-coding RNA (lncRNA) transcribed in the antisense direction relative to C8orf34. It plays a regulatory role at the RNA level, notably acting as a competing endogenous RNA (ceRNA) capable of binding and sequestering microRNA-671-5p. Through this mechanism, C8orf34-AS1 upregulates the expression of MFAP4, a key gene involved in suppressing lung adenocarcinoma cell migration and stemness. The lncRNA is implicated in the modulation of tumor behavior and immune microenvironment features—such as immune cell infiltration—in cancer, particularly in lung adenocarcinoma. There are no known direct drug interactions, and its primary therapeutic interest is as a non-coding RNA biomarker or potential gene regulation target[1][3][4].

Mechanism of action

Acts as a ceRNA by sponging miR-671-5p, thereby regulating the translation of MFAP4 May regulate target mRNAs such as CDH20 and FOXI3 through lncRNA–mRNA interaction Modulates tumor cell behavior (stemness and invasion) via the C8orf34-AS1/miR-671-5p/MFAP4 axis

Safety considerations

None described directly; as a non-protein-coding target with regulatory roles, therapeutic modulation risks are uncharacterized

Biomarkers

C8orf34-AS1 expression itself is a potential biomarker for genomic instability and stemness features in lung adenocarcinomamiR-671-5p and MFAP4 levels, as components of the regulatory axis, may serve as downstream biomarkers
