In the testing set, as shown in Figure 3 and Figure S2 (Supplementary Materials), the expression levels of GAS5, linc0597, lnc0640, lnc5150, lnc7074, lnc3643, lnc6655, and lnc7514 were consistent with the results from the training set; however, the levels of lnc-DC did not differ between SLE patients and healthy controls, but they did differ between SLE no LN patients and LN patients. Here, GAS5 is linked to lobular neoplasia.
