In breast cancer, over-expression of OTUD6B‐AS1 has been found to promote autophagy and thus genomic instability via the lncRNA OTUD6B-AS1/miR-26a-5p/MTDH signalling pathway, this lncRNA promotes the progression of triple-negative breast cancer 19. The gene discussed is MTDH; the disease is triple-negative breast carcinoma.
