Figure 3From: Stable low-level expression of p21WAF1/CIP1 in A549 human bronchogenic carcinoma cell line-derived clones down-regulates E2F1 mRNA and restores cell proliferation controlCombined endogenous plus exogenous p21 expression and E2F1 and MYC expression for A549, A549/p21 clone 1, 29, 30, and 32. Total p21 TA levels (e + e: endogenous plus exogenous), E2F1 TA levels, and MYC TA levels are indicated. Each column and error bar represents mean and standard deviation of at least triplicate measurements.Back to article page
