SMIM1 and cancer: Differential expression analysis showed three proteins significantly overexpressed in cancerous Thy3f nodules compared with non-cancer: kallikrein-related peptidase 11 (KLK11) (log2FC = 12; P = 0.001), α-1-acid glycoprotein 2 (A1AG2) (log2FC = 2; P = 0.007) and small integral membrane protein 1 (SMIM1) (log2FC = 2, P = 0.04).
