Description
RUNX1 transcription factor (TF) is a key regulator of megakaryocytic development and when mutated is associated with familial platelet disorder and predisposition to acute myeloid leukemia (FPD-AML). We used mice lacking Runx1 specifically in megakaryocytes (MKs) to characterize the Runx1-mediated transcriptional program during advanced stages of MK differentiation. Gene expression and chromatin-immunoprecipitation-sequencing (ChIP-seq) of Runx1 andp300identified functional Runx1-bound MK enhancers. Runx1/p300 co-bound regions showed significant enrichment in genes important for MK and platelet homeostasis. Runx1-bound regions were highly enriched in RUNX and ETS motifs and to a lesser extent in GATA motif.The data providesthe first example of genome-wide Runx1/p300 occupancy in maturating FL-MK,unravels the Runx1-regulated program controlling MK maturationin vivoandidentifies itsbona fideregulated genes. It advances our understandingof the molecular events that upon mutations in RUNX1 lead to thepredisposition to familial platelet disorders and FPD-AML.

Description
Myeloma is a clonal malignancy of plasma cells. Poor prognosis risk is currently identified by clinical and cytogenetic features. However, these indicators do not capture all prognostic information. Gene expression analysis can be used to identify poor prognosis patients and this can be improved by combination with information about DNA level changes. Using SNP-based gene mapping in combination with global gene expression analysis we have identified homozygous deletions in genes and networks that are relevant to myeloma. From these, we have generated an expression-based signature associated with shorter survival in 247 patients and confirmed this signature in data from 2 independent groups totalling 800 patients. We identified 170 genes with homozygous deletions and corresponding loss of expression. Deletion within the Cell Death network was over-represented and cases with these deletions have impaired overall survival. We defined a gene expression signature of 97 cell death genes that reflects prognosis confirmed this in two independent data sets. We developed a simple 6-gene expression signature from the 97-gene signature that can be used to identify poor prognosis myeloma in the clinical environment. The signature can form the basis of future trials aimed at improving the outcome of poor prognosis myeloma.

Description
RUNX3 is one of three mammalian Runt-domain transcription factors that regulate gene expression in several types of immune cells. Runx3-deficiency in mice is associated with a multitude of defects in the adaptive and innate immunity systems, including the development of early onset colitis. Our study reveals that conditional deletion of Runx3 specifically in mononuclear phagocytes (MNP) recapitulates the early onset spontaneous colitis seen in Runx3-/- mice. We show that Runx3 is expressed in colonic MNP, including RM and the dendritic cell cDC2 subsets and its loss results in impaired differentiation/maturation of both cell types.

Description
Conversion of fibroblasts to functional cardiomyocytes represents a potential approach for restoring cardiac function following myocardial injury, but the technique thus far has been slow and inefficient. To improve the efficiency of reprogramming fibroblasts to cardiac-like myocytes (iCMs) by cardiac transcription factors (Gata4, Hand2, Mef2c, and Tbx5=GHMT), we screened 192 protein kinases and discovered that Akt/protein kinase B dramatically accelerates and amplifies this process. Approximately 50% of reprogrammed fibroblasts displayed spontaneous beating after three weeks of induction by Akt plus GHMT. Furthermore, addition of Akt1 to GHMT evoked a more mature cardiac phenotype for iCMs, as seen by enhanced polynucleation, cellular hypertrophy, gene expression, and metabolic reprogramming. Igf1 and Pi3 kinase acted upstream of Akt, whereas mTORC1 and Foxo3a acted downstream of Akt to influence fibroblast-to-cardiomyocyte reprogramming. These findings provide new insights into the molecular basis of cardiac reprogramming and represent an important step toward further application of this technique. Overall design: We performed RNA-Seq using either isolated adult mouse ventricular cardiomyocytes (CMs) or MEFs treated for three weeks with empty vector, GHMT (iCMs cell sorted using aMHC-GFP before RNA-Seq), or AGHMT (iCMs cell sorted using aMHC-GFP before RNA-Seq).
