PIP4K2C and type 1 diabetes mellitus: A disease pathway network was made based on the T1DM-related ceRNA regulatory network, which consisted of four lncRNAs (LINC01278, TRG-AS1, MIAT, and GAS5-AS1), one miRNA (hsa-miR-181a), six target genes, as well as three important pathways related to T1DM, including the phosphatidylinositol signaling system (involving PIP4K2A, INPP4A, PIP4K2C, and CALM1), the dopaminergic synapse (involving CALM1 and PPP2R5C), and the insulin signaling pathway (involving CBLB and CALM1).
