| Abstract: | Cell proliferation and cellular differentiation are often thought of as opposing phenomena. The molecular mechanisms by which steroid, retinoid and thyroid hormones inhibit cellular proliferation and by which growth factors stimulate this process are poorly understood. We discuss recent evidence suggesting that these two signal transduction pathways converge through a process referred to as 'cross-coupling', which involves a possible interaction between steroid hormone receptors and the c-Jun oncoprotein. |
