Figure 7From: Stable low-level expression of p21WAF1/CIP1 in A549 human bronchogenic carcinoma cell line-derived clones down-regulates E2F1 mRNA and restores cell proliferation controlFlow cytometric DNA analysis on A549, A549/p21 clone 1, 29, 30, and 32. A) Determination of DNA content and events or cell number for parental A549 and A549/p21 clones constitutively expressing p21 (B-E) were performed as described in Methods and [50].Back to article page
