Defining the precise molecular strategies that coordinate patterns of transcriptional responses to specific signals is central for understanding normal development and homeostasis as well as the pathogenesis of hormone-dependent cancers. Here we report specific prostate cancer cell/macrophage interactions that mediate a switch in function of selective androgen receptor antagonists/modulators (S...
Enteropathogenic E. coli (EPEC) and related enterobacteria rely on a type III secretion system (T3SS) effector NleE to block host NF-κB signaling. NleE is a first in class, novel S-adenosyl-L-methionine (SAM)-dependent methyltransferase that methylates a zinc-coordinating cysteine in the Npl4-like Zinc Finger (NZF) domains in TAB2/3 adaptors in the NF-κB pathway, but its mechanism of action and...
The first adult-repopulating hematopoietic stem cells (HSCs) emerge in the mouse aorta-gonad-mesonephros (AGM) region at embryonic day 10.5 prior to their appearance in the yolk sac and fetal liver. Although several genes are implicated in the regulation of HSCs, there are gaps in our understanding of the processes taking place in the AGM at the time of HSC emergence. To identify genes involved...
The protein kinase TAK1 (transforming growth factor-beta-activated kinase 1), which has been implicated in the activation of MAPK (mitogen-activated protein kinase) cascades and the production of inflammatory mediators by LPS (lipopolysaccharide), IL-1 (interleukin 1) and TNF (tumour necrosis factor), comprises the catalytic subunit complexed to the regulatory subunits, termed TAB (TAK1-binding...
The role of receptor tyrosine kinases (RTKs) in transmembrane signaling is well established. Recently, ligand-dependent translocation of RTKs to the nucleus has been reported, but the functional importance of this process remains unclear. In this issue, Sardi et al. (2006) provide evidence for direct signaling in the nucleus by an intracellular ErbB4 receptor fragment that is released upon rece...
