OTUD6B antisense RNA 1 (OTUD6B-AS1)

OTUD6B antisense RNA 1 (OTUD6B-AS1) is a long noncoding antisense RNA transcribed from the opposite DNA strand of the OTUD6B gene on chromosome 8, typically found in the nucleus. Functionally, OTUD6B-AS1 regulates gene expression through both transcriptional and post-transcriptional mechanisms, including acting as a molecular sponge for microRNAs. It primarily affects cell proliferation, cell cycle progression (notably by influencing cyclin D1 levels), apoptosis, and signaling pathways such as Wnt/β-catenin. In the context of human disease, OTUD6B-AS1 has emerging roles in cancer biology—cell proliferation, invasion, migration, and prognosis—and has functional impacts in fibrotic diseases like systemic sclerosis. Current evidence does not support OTUD6B-AS1 as a classical drug target, but its expression may be valuable as a molecular biomarker in oncology and related research applications.

Knockdown of OTUD6B-AS1 (antisense oligonucleotides) leads to reduced cell proliferation and increased apoptosis via decreased cyclin D1 expression. Knockdown inhibits the Wnt/β-catenin pathway and impacts EMT-related protein regulation in cancer models. Acts as a competing endogenous RNA (ceRNA), sequestering specific microRNAs (e.g., miR-664b-3p), which regulate downstream oncogenic pathways.
