Figure 2From: Activation of p53, inhibition of telomerase activity and induction of estrogen receptor beta are associated with the anti-growth effects of combination of ovarian hormones and retinoids in immortalized human mammary epithelial cellsInhibition of 76N TERT cell growth by E/P and retinoids. Cells were treated with indicated retinoids with or without E/P for 24 hours and then labelled with [3H]thymidine as described under "Materials and Methods". Data are the means ± SE from 3–4 experiments. *, significant differences from control.Back to article page
