Differential expression of decorin, EGFR and cyclin D1 during mammary gland carcinogenesis in TA2 mice with spontaneous breast cancer

Table 3 EGFR staining in normal mammary glands and tumor tissues from TA2 mice(expressed as a percentage of samples with positive staining)

	n	Positive expression	Nuclear translocation	High expression level
Group A	12	33.33(4/12)	0.00(0/12)	0.00(0/12)
Group B	28	78.57(22/28)^#	53.57(15/28)^#	42.86(12/28)*
Group C	28	64.29(18/28)^#	39.28(11/28)^#	17.86(5/28)

^#: compared with Group A, P < 0.05; *: compared with Group C, P < 0.05
Group A: normal mammary glands from five month-old TA2 mice; Group B: normal mammary glands from spontaneous breast cancer-bearing TA2 mice; Group C: spontaneous breast cancer tissue from TA2 mice.
