GenomicsPrep1 and Meis1 competition for Pbx1 binding regulates protein stability and tumorigenesis.
Prep1 is a tumor-suppressor, whereas Meis1 is an oncogene. We show that to perform these activities in MEFs both proteins competitively hetero-dimerize with Pbx1. Meis1 alone transforms Prep1-deficient fibroblasts while Prep1 overexpression inhibits Meis1 tumorigenicity. Pbx1 can therefore alternati...

TranscriptomicsLinkage of Meis1 leukemogenic activity to multiple downstream effectors including Trib2 and Ccl3
OBJECTIVE: MEIS1, a HOX cofactor, collaborates with multiple HOX and NUP98-HOX fusion proteins to accelerate the onset of acute myeloid leukemia (AML) through largely unknown molecular mechanisms. MATERIALS AND METHODS: To further resolve these mechanisms, we conducted a structure-function analysis ...

TranscriptomicsIdentification of gene targets of Meis1
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 persiste...

ProteomicsInteraction between Malat1 and miR-499-5p regulates Meis1 expression and function with a net impact on cell proliferation
Meis1 is a transcription factor involved in a broad range of functions including development and proliferation and has been previously shown to harness cell cycle progression. This study aimed to investigate the regulation of Meis1 by long non-coding RNAs (lncRNAs) and their sponged microRNAs (miRNA...

GenomicsGenome-wide co-occupancy of Hoxa9 and C/EBPα in Hoxa9/Meis1 transformed HSCs [ChIP-seq]
Identification of the genome-wide binding sites of Hoxa9 and C/EBPα in a murine myeloblastic cell line transformed by Hoxa9/Meis1. Over 50% of Hoxa9 binding sites are co-bound by C/EBPα, providing mechanistic insight into the requirement of C/EBPα for Hoxa9-mediated leukemogenesis. Additionally, gen...

TranscriptomicsGene expression profiles upon Meis1 knockout in Hoxa9/Meis1-induced AML
Meis1 is found cooperatively activated with Hoxa7/a9 in AML, and it indeed promotes leukemogenic activities of Hoxa9. It is important to identify downstream target genes of Meis1 to understand its cooperative activity with Hoxa9 in leukemogenesis. We used microarrays to detail the global programme o...

TranscriptomicsThe role of Hoxa9 and Meis1 in development of acute myeloid leukemia (mRNA)
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...
