Breast cancer has a higher incidence, and aggressive behavior is higher in males and postmenopausal females compared with premenopausal females.3 We analyzed the expression of LINC00263 in breast cancer patients of different ages and found that LINC00263 was highly expressed in patients under 45 years old, but it was highly expressed in normal tissues from older patients (Supplementary Fig. 6c).38 But there was no significant difference in breast cancer survival after subdivided by age (Supplementary Fig. 6d, e). Here, OLMALINC is linked to breast cancer.
