SYT7 and gastric cancer: Moreover, we found that up-regulated SYT4, SYT9, and SYT14 were significantly correlated with a worse PFS (P = 0.032, P = 0.007, and P < 0.001, respectively) (Figure 3), whereas the expressions of SYT1, SYT2, SYT3, SYT5, SYT6, SYT7, SYT8, SYT10, SYT11, SYT12, SYT13, SYT15, SYT16, and SYT17 were not associated with PFS for GC patients (P = 0.994, P = 0.059, P = 0.124, P = 0.094, P = 0.182, P = 0.611, P = 0.514, P = 0.289, P = 0.141, P = 0.08, P = 0.398, P = 0.069, P = 0.051, and P = 0.064) (Figure S3).
