In colorectal cancer, we showed that LINC00263 was highly expressed in male patients compared to female patients (Fig. 5a, b), whereas there was no such difference in normal colorectal tissue (Supplementary Fig. 4g–i) and the high expression of LINC00263 was a significant disadvantage in colorectal cancer (Fig. 5c). The gene discussed is OLMALINC; the disease is colorectal cancer.
