Moreover, the microscopic observation of tumours revealed that tumours that developed in the shcontrol cohort showed stronger Ki-67 expression than those in the shLINC00511 cohort, and the tumours that developed in the shLINC00511 cohort showed stronger CDKN1B expression than those that developed in the shcontrol cohort, as detected by immunohistochemistry (IHC) analysis (Fig. 6g). The gene discussed is CDKN1B; the disease is neoplasm.
