To investigate the role of PRR11 in breast cancer, the expression of PRR11 was obtained from GEPIA, and the data showed that PRR11 expression was up-regulated in breast cancer tissues (Figure 1B, number of tumor (T) = 1085, number of normal (N) = 291, P<0.05), suggesting that PRR11 may promote breast cancer development and progression. The gene discussed is PRR11; the disease is neoplasm.
