TNF time course series of HelA tet off cells cultured in presence or absence of Dox; TNF is a pro-inflammatory cytokine that controls expression of inflammatory genetic networks. Although the Nuclear Factor-kB (NF-kB) pathway is crucial for mediating cellular TNF responses, the complete spectrum of...

Bacterial nucleoid-associated proteins play important roles in chromosome organization and global gene regulation. We find that Lsr2 of Mycobacterium tuberculosis is a novel nucleoid-associated protein that specifically binds AT-rich regions of the genome, including regions encoding major virulence ...
