- The MAPK(ERK-1,2) pathway integrates distinct and antagonistic signals from TGFalpha and FGF7 in morphogenesis of mouse mammary epitheliumJimmie E Fata
Life Sciences Division, Lawrence Berkeley National Laboratory, Berkeley, CA 94720, USA
Dev Biol 306:193-207. 2007..Our findings indicate that expression of morphogenetic effectors, proliferation, and cell-type decisions during mammary organoid morphogenesis are intimately dependent on the duration of activation of MAPK(ERK1,2) activation...
- GATA-3 links tumor differentiation and dissemination in a luminal breast cancer modelHosein Kouros-Mehr
