Alzheimer's disease (AD) affects memory and neurogenesis. Adult neurogenesis plays an important role in memory function and impaired neurogenesis contributes to cognitive deficits associated with AD. Increased physical/ cognitive activity is associated with both reduced risk of dementia and increased neurogenesis. Previous attempts to restore hippocampal(More)
Through a targeted knockdown (KD) screen of chromatin regulatory genes, we identified the EP400 complex components EPC1 and EPC2 as critical oncogenic cofactors in acute myeloid leukemia (AML). EPC1 and EPC2 were required for the clonogenic potential of human AML cells of multiple molecular subtypes. Focusing on MLL-mutated AML as an exemplar, Epc1 or Epc2(More)
Given the importance of deregulated phosphoinositide (PI) signaling in leukemic hematopoiesis, genes coding for proteins that regulate PI metabolism may have significant and as yet unappreciated roles in leukemia. We performed a targeted knockdown (KD) screen of PI modulator genes in human acute myeloid leukemia (AML) cells and identified candidates(More)
The EVI1 (ecotropic viral integration site 1) gene at 3q26 codes for a transcriptional regulator with an essential role in haematopoiesis. Overexpression of EVI1 in acute myeloid leukaemia (AML) is frequently associated with 3q26 rearrangements and confers extremely poor prognosis. EVI1 mediates transcriptional regulation, signalling, and epigenetic(More)
Using a screening strategy, we identified the tetratricopeptide repeat (TPR) motif protein, Tetratricopeptide repeat domain 5 (TTC5, also known as stress responsive activator of p300 or Strap) as required for the survival of human acute myeloid leukemia (AML) cells. TTC5 is a stress-inducible transcription cofactor known to interact directly with the(More)
