Heme oxygenase-1 (HO-1), a cytoprotective, pro-angiogenic and anti-inflammatory enzyme, is strongly induced in injured tissues. Our aim was to clarify its role in cutaneous wound healing. In wild type mice, maximal expression of HO-1 in the skin was observed on the 2(nd) and 3(rd) days after wounding. Inhibition of HO-1 by tin protoporphyrin-IX resulted in(More)
JNK and p38 phosphorylate a diverse set of substrates and, consequently, can act in a context-dependent manner to either promote or inhibit tumor growth. Elucidating the functions of specific substrates of JNK and p38 is therefore critical for our understanding of these kinases in cancer. ATF2 is a phosphorylation-dependent transcription factor and(More)
Transcription factors ATF2 (activating transcription factor 2) and ATF7 (activating transcription factor 7) are highly homologous members of the activator protein 1 (AP-1) family. Their activities are growth factor and stress stimulated and they strictly require phosphorylation by mitogen-activated protein (MAP) kinases for their transcriptional functions.(More)
