Diverse expression patterns of mucin 2 in colorectal cancer indicates its mechanism related to the intestinal mucosal barrier

Table 1 Comparison of mucin 2 expression in normal and cancer tissues of patients with colorectal cancer (cases)

Group	MUC2 expression		χ2	P value
	Low	High
Normal tissues	21	79	14.028	< 0.011
Cancer tissues	46	54

¹Indicates that the difference was statistically significant, which confirmed that the expression difference of mucin 2 (MUC2) in normal tissues and cancer tissues was statistically significant, and the high expression rate of MUC2 in cancer tissues was lower than that in normal tissues. MUC2: Mucin 2.
