Table 4 Cyclin D1 and PCNA labeling index of normal mammary glands and cancer tissues from spontaneous breast cancer -bearing TA2 mice (%)

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

  n Cyclin D1 PCNA
Group B
   Nucleus EGFR (+) 15 15.15 ± 5.16* 37.81 ± 12.77
   Nucleus EGFR (-) 13 8.77 ± 7.95 33.71 ± 15.78
Group C
   Nucleus EGFR (+) 11 31.17 ± 12.50* 44.9212.01
   Nucleus EGFR (-) 17 18.54 ± 17.98 33.9413.92
  1. *:compared to samples without nuclear EGFR expression, P < 0.05
  2. Group B: normal mammary glands from spontaneous breast cancer-bearing TA2 mice; Group C: spontaneous breast cancer tissue from TA2 mice.
