Western blot analysis showed that the relative expression of GPLD1 among the four cohorts [LADA (n = 174), classic type 1 diabetes (n = 156), T2DM (n = 195) and normal controls (n = 166)] was 0.84±0.02, 0.88±0.02, 0.59±0.01, and 0.60±0.01, respectively. The gene discussed is GPLD1; the disease is type 1 diabetes mellitus.
