Consistent with the mRNA levels of SMARCA1, SMARCA2, SMARCA4, SMARCA5, HELLS, and SMARCAL1, a significant difference was found in patients with pancreatic cancer (P < 0.05), and the mRNA levels of SMARCA3 and SMARCAD1 displayed no significant difference between the pancreatic cancer group and the control group (P > 0.05) (Fig. 3B). Here, SMARCAL1 is linked to familial pancreatic carcinoma.
