(G) qPCR analysis of stomach-restricted gene set between KL ADC and KLN mucinous tumor sections (n=3 or 4 per group). Results were shown in a box and whisker plot with the minimum value, first quartile, median, third quartile and maximum value. The box represented the 50% of the central data, with a line inside represented the median. The significance was calculated by two-tailed unpaired Student's t-test with Welch's correction. *p=0.0260 (Hnf4α), *p=0.0275 (Vsig1), *p=0.0122 (Gkn3), *p=0.0324 (Ctse), **p=0.0084 (Onecut2).
