Moreover, the oncogenic lncRNA HOXA cluster antisense RNA 2 (HOXA-AS2) was found to promote the stemness of bladder cancer cells by elevating the expression levels of the cancer stem cell markers ALDH1A1, CD44, HMGA2, KLF4, and OCT4 by regulating the miR-125b/smad2 axis [103]. The gene discussed is ALDH1A1; the disease is urinary bladder cancer.
