ARHGEF18 antisense RNA 1 (ARHGEF18-AS1)

ARHGEF18 antisense RNA 1 (ARHGEF18-AS1) is a non-coding RNA transcript classified as an antisense long noncoding RNA (lncRNA)[1][3][6]. It is transcribed from the strand complementary to the ARHGEF18 gene, a known Rho/Rac guanine nucleotide exchange factor involved in actin cytoskeleton organization[1][4]. While the specific biological functions and disease roles of ARHGEF18-AS1 have not been experimentally delineated, antisense lncRNAs in general are important regulators of gene expression, often modulating the expression of their sense gene at transcriptional or post-transcriptional levels[3][6]. They are increasingly recognized for their roles in epigenetic modification and regulation of cellular processes, and their dysregulation can contribute to human diseases, especially cancers[3]. There are currently no known drugs targeting ARHGEF18-AS1 and it is not considered a therapeutic target in itself.
