T-C2 comprised one-fourth of the tumor section and showed relatively high expression of TNNI2 (troponin I2, a fast-twitch skeletal muscle protein) and SYT8 (synaptotagmin 8 and a membrane protein that is important in neurotransmission and hormone secretion, Figures S5E–G), which have been found to promote PC (18, 19). Here, SYT8 is linked to neoplasm.
