Analysis of forebrain from male and female E12.5 embryos heterozygous for the Meis1tm1Mtor allele. These animals express only one functional allele of Meis1, modeling the reduced expression of MEIS1 in Restless Legs Syndrome (RLS) patients. Results provide insight the role of MEIS1 in RLS.

(Submitter supplied) Genome-wide association studies (GWASs) identified the MEIS1 locus for Restless Legs Syndrome (RLS), but causal single nucleotide polymorphisms (SNPs) and the functional relevance have remained to be elucidated. The MEIS1 locus contains an exceptionally large number of highly conserved non-coding regions (HCNRs), which potentially function as cis-regulatory modules. We analyzed the HCNRs in the RLS-associated linkage disequilibrium (LD) block for allele-dependent enhancer activity in both zebrafish and mouse, comparing the protective and risk alleles of RLS-associated common variants. more...

Analysis of forebrain from male adults heterozygous for the Meis1tm1Mtor allele. These animals express only one functional allele of Meis1, modeling the reduced expression of MEIS1 in Restless Legs Syndrome (RLS) patients. Results provide insight the role of MEIS1 in RLS pathogenesis.

(Submitter supplied) Objective: Homozygous loss-of-function mutations in the gene coding for the homeobox transcription factor (TF) PDX1 leads to pancreatic agenesis, whereas heterozygous mutations can cause Maturity-Onset Diabetes of the Young 4 (MODY4). Although the function of Pdx1 is well studied in pre-clinical models during insulin-producing β-cell development and homeostasis, it remains elusive how this TF controls human pancreas development by regulating a downstream transcriptional program. more...

(Submitter supplied) Microphthalmos is a rare congenital anomaly characterized by reduced eye size and visual deficits of variable degrees. Sporadic and hereditary microphthalmos has been associated to heterozygous mutations in genes fundamental for eye development. Yet, many cases are idiopathic or await the identification of molecular causes. Here we show that haploinsufficiency of Meis1, a transcription factor with an evolutionary conserved expression in the embryonic trunk, brain and sensory organs, including the eye, causes microphthalmic traits and visual impairment, in adult mice. more...

(Submitter supplied) OBJECTIVE: MEIS1, a HOX cofactor, collaborates with multiple HOX proteins, such as HOXA9, to accelerate the onset of acute myeloid leukemia (AML) through largely unknown molecular mechanisms. To further resolve these mechanisms, we conducted a structure-function analysis of Meis1 and gene expression profiling, in the context of Hoxa9 leukemogenesis. RESULTS: We show, in a murine bone marrow transplantation model, that the homeodomain of Meis1 is required for leukemogenic collaboration with Hoxa9. more...

(Submitter supplied) The homeodomain protein Meis1 is essential for definitive hematopoiesis and vascular patterning in the mouse embryo. Our present study suggested it exerts two distinguishable effects in differentiating ES cells. First, it increases the numbers of hematopoietic progenitors and extends their persistence in culture. Second, Meis1 skews hematopoietic differentiation by suppressing erythroid while enhancing megakaryocytic progenitor differentiation. more...

(Submitter supplied) The homeodomain protein Meis1 is essential for definitive hematopoiesis and vascular patterning in the mouse embryo. Meis2, another member of the same family, shares 82% protein identities with Meis1. Our present study suggested Meis2 exerts two distinguishable effects in differentiating ES cells. First, it increases the numbers of hematopoietic progenitors and extends their persistence in culture. more...

(Submitter supplied) Previously, we reported that the transcription factor Mesp1 promotes the cell fates of cardiomyocytes, smooth muscle, and vascular endothelium. Recently, hematopoietic stem cells (HSCs) were shown to derive from hemogenic endothelium. Since Mesp1 regulates development of endothelium, it potentially could influence gene expression related to hematopoietic development. Our present fate mapping study found that Mesp1-cre efficiently labeled hematopoietic lineages in vivo. more...

(Submitter supplied) To investigate whether co-expression of PBX3/MEIS1 can mimic that of MLL-AF9, HOXA9/MEIS1 or HOXA9/PBX3 in inducing leukemogenesis, we conducted in vivo mouse bone marrow transplantation (BMT) assays. Briefly, normal mouse bone marrow (BM) progenitor (i.e., lineage negative; Lin-) cells collected from B6.SJL (CD45.1) donor mice (CD45.1) were retrovirally co-transduced with MSCVneo-MLL-AF9+MSCV-PIG (MLL-AF9), MSCVneo-HOXA9+MSCV-PIG (HOXA9), MSCVneo-HOXA9+MSCV-PIG-MEIS1 (HOXA9+MEIS1), MSCVneo-HOXA9+MSCV-PIG-PBX3 (HOXA9+PBX3), MSCV-PIG-PBX3+MSCVneo-MEIS1 (PBX3+MEIS1), MSCVneo+MSCV-PIG-PBX3 (PBX3) , MSCVneo+MSCV-PIG-MEIS1 (MEIS1), or MSCVneo+MSCV-PIG (normal control; NC). more...
