Hematopoietic stem and progenitor cell (HSPC) formation and lineage differentiation involve gene expression programs orchestrated by transcription factors and epigenetic regulators. Genetic disruption of the chromatin remodeler chromodomain-helicase-DNA-binding protein 7 (CHD7) expanded phenotypic HSPCs, erythroid, and myeloid lineages in zebrafish and mouse embryos. CHD7 acts to suppress hematopoietic differentiation.

RUNX1 is frequently mutated in myeloid and lymphoid malignancies. It has been shown to negatively regulate Toll-like receptor 4 (TLR4) signaling through nuclear factor κB (NF-κB) in lung epithelial cells. Here we show that RUNX1 regulates TLR1/2 and TLR4 signaling and inflammatory cytokine production by neutrophils.

Calcium ions are a well-known essential component for pollen germination and tube elongation. Several calcium-dependent protein kinases (CDPKs) are expressed predominantly in mature pollen grains and play a critical role in pollen. However, none of their interacting proteins or downstream substrates has been identified.

AML1-ETO and TEL-AML1 are chimeric proteins resulting from the t(8;21)(q22;q22) in acute myeloid leukemia, and the t(12;21)(p13;q22) in pre-B-cell leukemia, respectively. The Runt domain of AML1 in both proteins mediates DNA binding and heterodimerization with the core binding factor beta (CBFbeta) subunit. To determine whether CBFbeta is required for AML1-ETO and TEL-AML1 activity, we introduced amino acid substitutions into the Runt domain that disrupt heterodimerization with CBFbeta but not DNA binding.
