UBE2Q1 and breast cancer: We performed uni- and multi-Cox regression and LASSO regression, whereby seven arlncRNAs were validated for the construction of risk models, including UBE2Q1-AS1 that constituted a prognostic model for gastric cancer (27), `MAFG-DT` which was also a crucial member of the prognostic model for breast cancer (28), and AC112721.2 that regulated breast cancer expression through the TGF-β signaling pathway (29).
