abstract：:Activating mutations of FLT3 occur in about 30% of acute myeloid leukemia (AML) cases and are associated with relapse and poor prognosis. Midostaurin is the first drug approved for AML since 2000, and the first multi-kinase inhibitor approved for the FLT3-mutant subtype. To view this Bench to Bedside, open or download...

abstract：:During the SOS response, LexA repressor is inactivated by specific cleavage. Although cleavage requires RecA protein in vivo, RecA acts indirectly as a coprotease by stimulating an inherent self-cleavage activity of LexA. In lambda lysogens, cleavage of lambda Cl repressor in a similar but far slower reaction results ...
