Indispensable role of the transcription factor PEBP2/CBF in angiogenic activity of a murine endothelial cell MSS31. (1/86)

Mice lacking the AML1/PEBP2alphaB/CBFa2 gene or PEBP2beta/CBFb gene exhibit a defect in definitive hematopoiesis and die in utero because of hemorrhage in the central nervous system. Hematopoiesis in the embryo is considered to be tightly associated with vascular development. Here we examined whether PEBP2/CBF plays any role in angiogenesis besides that in definitive hematopoiesis. We found that AML1/PEBP2alphaB/CBFa2, PEBP2alphaA/CBFa1, and PEBP2beta/CBFb were expressed in a murine endothelial cell line MSS31. The expression of these molecules as well as the DNA binding activity of PEBP2/CBF were augmented by angiogenic growth factors such as bFGF and VEGF. Moreover, the expression of PEBP2 alpha/CBFa protein in endothelial cells was confirmed at the site of angiogenesis in vivo. To further clarify the role of PEBP2/CBF in angiogenesis, we established permanent transfectants of PEBP2 beta-MYH11 gene, one that interacts with the runt domain of the alpha subunit and deregulates PEBP2/CBF in a dominant interfering manner. Proliferation, migration, and tube formation of the PEBP2 beta-MYH11 transfectants were significantly reduced in comparison with those activities of the mock transfectants. These results suggest that transcription factor PEBP2/CBF plays an important role in angiogenesis.  (+info)

Zebrafish homolog of the leukemia gene CBFB: its expression during embryogenesis and its relationship to scl and gata-1 in hematopoiesis. (2/86)

Mammalian CBFB encodes a transcription factor (CBF beta) that in combination with CBF alpha 2 binds to specific DNA sequences and regulates expression of a number of hematopoietic genes. CBFB is associated with human leukemias through a chromosome 16 inversion and is essential for definitive hematopoiesis during mouse embryo development. We have isolated a zebrafish cbfb complementary DNA (cDNA) clone from a zebrafish kidney cDNA library. This cbfb is highly homologous to human and mouse CBFB/Cbfb genes at both the DNA and protein level. In biochemical analyses, cbfbeta binds to human CBF alpha 2 and enhances its DNA binding. During zebrafish development, cbfb is expressed in the lateral plate mesoderm at tail bud stage and in the intermediate cell mass (ICM, the location of embryonic hematopoiesis) between the 21- to 26-somite stages. The cbfb is also expressed in Rohon-Beard cells, cranial nerve ganglia, hindbrain, retina, branchial arches, jaw, and fin buds. Expression of cbfb is decreased or absent in the ICM and Rohon-Beard cells in some hematopoietic mutants and is unaffected in others. We have also analyzed the expression of scl and gata-1 in the same hematopoietic mutants to ascertain the relative order of these transcription factors to cbfb in zebrafish hematopoiesis. Our results indicate that cbfb is expressed in early hematopoietic progenitors and that its expression pattern in the hematopoietic mutants is similar to that of scl.

Core-binding factor beta (CBFbeta), but not CBFbeta-smooth muscle myosin heavy chain, rescues definitive hematopoiesis in CBFbeta-deficient embryonic stem cells. (3/86)

Core-binding factor beta (CBFbeta) is the non-DNA-binding subunit of the heterodimeric CBFs. Genes encoding CBFbeta (CBFB), and one of the DNA-binding CBFalpha subunits, Runx1 (also known as CBFalpha2, AML1, and PEBP2alphaB), are required for normal hematopoiesis and are also frequent targets of chromosomal translocations in acute leukemias in humans. Homozygous disruption of either the Runx1 or Cbfb gene in mice results in embryonic lethality at midgestation due to hemorrhaging in the central nervous system, and severely impairs fetal liver hematopoiesis. Results of this study show that Cbfb-deficient mouse embryonic stem (ES) cells can differentiate into primitive erythroid colonies in vitro, but are impaired in their ability to produce definitive erythroid and myeloid colonies, mimicking the in vivo defect. Definitive hematopoiesis is restored by ectopic expression of full-length Cbfb transgenes, as well as by a transgene encoding only the heterodimerization domain of CBFbeta. In contrast, the CBFbeta-smooth muscle myosin heavy chain (SMMHC) fusion protein generated by the inv(16) associated with acute myeloid leukemias (M4Eo) cannot rescue definitive hematopoiesis by Cbfb-deficient ES cells. Sequences responsible for the inability of CBFbeta-SMMHC to rescue definitive hematopoiesis reside in the SMMHC portion of the fusion protein. Results also show that the CBFbeta-SMMHC fusion protein transdominantly inhibits definitive hematopoiesis, but not to the same extent as homozygous loss of Runx1 or Cbfb. CBFbeta-SMMHC preferentially inhibits the differentiation of myeloid lineage cells, while increasing the number of blastlike cells in culture.  (+info)

Primary chromosomal rearrangements of leukemia are frequently accompanied by extensive submicroscopic deletions and may lead to altered prognosis. (4/86)

BCR/ABL fluorescent in situ hybridization study of chronic myeloid leukemia (CML) and Philadelphia(+) (Ph(+)) acute lymphoid leukemia (ALL) indicated that approximately 9% of patients exhibited an atypical hybridization pattern consistent with a submicroscopic deletion of the 5' region of ABL and the 3' region of the BCR genes on the 9q(+) chromosome. The CML patients with deletions had a shorter survival time and a high relapse rate following bone marrow transplant. Since deletions are associated with both Ph(+) CML and ALL, it seemed probable that other leukemia-associated genomic rearrangements may also have submicroscopic deletions. This hypothesis was confirmed by the detection of deletions of the 3' regions of the CBFB and the MLL genes in AML M4 patients with inv(16) and in patients with ALL and AML associated with MLL gene translocations, respectively. In contrast, analysis of the AML M3 group of patients and AML M2 showed that similar large deletions were not frequently associated with the t(15;17) or t(8;21) translocations. Analysis of sequence data from each of the breakpoint regions suggested that large submicroscopic deletions occur in regions with a high overall density of Alu sequence repeats. These findings are the first to show that the process of deletion formation is not disease specific in leukemia and also implicate that the presence of repetitive DNA in the vicinity of breakpoint regions may facilitate the generation of submicroscopic deletions. Such deletions could lead to the loss of one or more genes, and the associated haploinsufficiency may result in the observed differences in clinical behavior. (Blood. 2001;97:3581-3588)  (+info)

Cloning and expression pattern of a novel PEBP2 beta-binding protein (charged amino acid rich leucine zipper-1[Crl-1]) in the mouse. (5/86)

PEBP2 beta/Cbf beta is the beta subunit of PEBP2/Cbf, which has been demonstrated to have important biological activities in hematopoiesis and osteogenesis. However, PEBP2 beta is ubiquitously expressed, suggesting that PEBP2 has other additionally important physiological activities. In an effort to elucidate other possible functions for PEBP2, we have isolated a novel gene that encodes a PEBP2 beta-interacting protein from a mouse cDNA library. We have called this gene Crl-1 for charged amino acid rich leucine zipper-1 (Crl-1) because it is rich in charged amino acids and contains a putative leucine zipper region. Expression studies in a 17.5 days post-coitum mouse embryo demonstrated Crl-1 expression mainly in the olfactory bulb and cerebral cortex. Post-natally, Crl-1 expression was additionally observed in the cerebellar cortex with strong expression in the hippocampus. These findings show that this novel PEBP2 beta-interacting protein is expressed mainly in subsets of neuronal cells, suggesting that Crl-1 plays some role in the developing mouse brain.  (+info)

Role of Cbfb in hematopoiesis and perturbations resulting from expression of the leukemogenic fusion gene Cbfb-MYH11. (6/86)

Core-binding factor beta (CBFbeta) and CBFalpha2 form a heterodimeric transcription factor that plays an important role in hematopoiesis. The genes encoding either CBFbeta or CBFalpha2 are involved in chromosomal rearrangements in more than 30% of cases of acute myeloid leukemia (AML), suggesting that CBFbeta and CBFalpha2 play important roles in leukemogenesis. Inv(16)(p13;q22) is found in almost all cases of AML M4Eo and results in the fusion of CBFB with MYH11, the gene encoding smooth muscle myosin heavy chain. Mouse embryos heterozygous for a Cbfb-MYH11 knock-in gene lack definitive hematopoiesis, a phenotype shared by Cbfb(-/-) embryos. In this study we generated a Cbfb-GFP knock-in mouse model to characterize the normal expression pattern of Cbfbeta in hematopoietic cells. In midgestation embryos, Cbfbeta was expressed in populations enriched for hematopoietic stem cells and progenitors. This population of stem cells and progenitors was not present in mouse embryos heterozygous for the Cbfb-MYH11 knock-in gene. Together, these data suggest that Cbfb-MYH11 blocks embryonic hematopoiesis at the stem-progenitor cell level and that Cbfb is essential for the generation of hematopoietic stem and progenitor cells. In adult mice, Cbfbeta was expressed in stem and progenitor cells, as well as mature myeloid and lymphoid cells. Although it was expressed in erythroid progenitors, Cbfbeta was not expressed during the terminal stages of erythropoiesis. Our data indicate that Cbfb is required for myeloid and lymphoid differentiation; but does not play a critical role in erythroid differentiation.  (+info)

Distinct roles for c-Myb and core binding factor/polyoma enhancer-binding protein 2 in the assembly and function of a multiprotein complex on the TCR delta enhancer in vivo. (7/86)

Enhancers and promoters within TCR loci functionally collaborate to modify chromatin structure and to confer accessibility to the transcription and V(D)J recombination machineries during T cell development in the thymus. Two enhancers at the TCRalphadelta locus, the TCR alpha enhancer and the TCR delta enhancer (Edelta), are responsible for orchestrating the distinct developmental programs for V(D)J recombination and transcription of the TCR alpha and delta genes, respectively. Edelta function depends critically on transcription factors core binding factor (CBF)/polyoma enhancer-binding protein 2 (PEBP2) and c-Myb as measured by transcriptional activation of transiently transfected substrates in Jurkat cells, and by activation of V(D)J recombination within chromatin-integrated substrates in transgenic mice. To understand the molecular mechanisms for synergy between these transcription factors in the context of chromatin, we used in vivo footprinting to study the requirements for protein binding to Edelta within wild-type and mutant versions of a human TCR delta minilocus in stably transfected Jurkat cells. Our data indicate that CBF/PEBP2 plays primarily a structural role as it induces a conformational change in the enhanceosome that is associated with augmented binding of c-Myb. In contrast, c-Myb has no apparent affect on CBF/PEBP2 binding, but is critical for transcriptional activation. Thus, our data reveal distinct functions for c-Myb and CBF/PEBP2 in the assembly and function of an Edelta enhanceosome in the context of chromatin in vivo.  (+info)

Core binding factor genes and human leukemia. (8/86)

BACKGROUND: The core binding factor (CBF) transcription complex, consisting of the interacting proteins RUNX1 and CBFb, is essential for normal hematopoiesis. Recent studies have shown that mutations and gene rearrangements involving this complex are frequently implicated in leukemogenesis. Understanding the molecular events leading to the disruption of CBF has provided important insights into our understanding of the normal regulatory pathways that control hematopoiesis and has begun to reveal how alterations in these pathways induce leukemia. INFORMATION SOURCES: Both authors are involved in the identification and characterization of chromosomal abnormalities associated with hematologic malignancy. This has led to contributions to multicenter clinical and laboratory investigations as well as publications in peer-reviewed journals. All of the references cited in this review are published in journals covered by Medline. State of the Art. The core binding factor (CBF) is a heterodimeric transcription factor composed of the RUNX1 and CBFb subunits. RUNX1 is the DNA binding element of the complex and its affinity is greatly increased in the presence of CBFb. Knock-out studies in mice have demonstrated that both RUNX1 and CBFb are necessary for definitive hematopoiesis. Furthermore, reciprocal chromosomal translocations involving both partners have been directly implicated in leukemogenesis. Evidence is now emerging that at least some of the resulting fusion proteins, namely ETV6-RUNX1, RUNX1-MTG8 and CBFb-MYH11 dominantly inhibit the function of native CBF by recruiting transcriptional co-repressor complexes. However, knock-in studies have shown that whilst expression of these fusion genes may disrupt normal hematopoiesis, this, by itself, is not sufficient for the subsequent development of leukemia. Mutations of RUNX1 have been identified in familial platelet disorder (FDP), in which there is a congenital predisposition to the development of AML and heterozygous point mutations have been identified in the RUNX1 gene in some leukemias. Moreover, a small number of cases have been reported in which amplification of RUNX1 has been detected in childhood ALL suggesting mechanisms other than loss of function, such as gene dosage may also play a role. CONCLUSIONS: Understanding the role CBF plays in normal hematopoiesis and hematologic malignancies has provided critical reagents for the accurate identification of the broad group of leukemias harboring alterations of CBF. The application of these molecular approaches has already shown an impact on the clinical management of these patients and as more information becomes available, the ability to tailor therapy to improve each patient's chance of a cure becomes feasible.  (+info)

Complete information for CBFB gene (Protein Coding), Core-Binding Factor Beta Subunit, including: function, proteins, disorders, pathways, orthologs, and expression. GeneCards - The Human Gene Compendium
The protein encoded by this gene is the beta subunit of a heterodimeric core-binding transcription factor belonging to the PEBP2/CBF transcription factor family which master-regulates a host of genes specific to hematopoiesis (e.g., RUNX1) and osteogenesis (e.g., RUNX2). The beta subunit is a non-DNA binding regulatory subunit; it allosterically enhances DNA binding by alpha subunit as the complex binds to the core site of various enhancers and promoters, including murine leukemia virus, polyomavirus enhancer, T-cell receptor enhancers and GM-CSF promoters. Alternative splicing generates two mRNA variants, each encoding a distinct carboxyl terminus. In some cases, a pericentric inversion of chromosome 16 [inv(16)(p13q22)] produces a chimeric transcript consisting of the N terminus of core-binding factor beta in a fusion with the C-terminal portion of the smooth muscle myosin heavy chain 11. This chromosomal rearrangement is associated with acute myeloid leukemia of the M4Eo subtype. Two ...

Approximately 40% of patients affected by core binding factor (CBF) acute myeloid leukemia (AML) ultimately die from the disease. Few prognostic markers have been identified. In this study we reviewed 192 patients with core binding factor acute myeloid leukemia (AML), treated with curative intent (age, 15-79 years) in 11 Italian institutions. Overall, 10-year overall survival (OS), disease-free survival (DFS), and event-free survival were 63.9%, 54.8%, and 49.9%, respectively; patients with the t(8;21) and inv(16) chromosomal rearrangements exhibited significant differences at diagnosis. Despite similarly high complete remission (CR) rate, patients with inv(16) experienced superior DFS and a high chance of achieving a second CR, often leading to prolonged OS also after relapse. We found that a complex karyotype (ie, ≥4 cytogenetic anomalies) affected survival; the KIT D816 mutation predicted worse prognosis only in patients with the t(8;21) rearrangement, whereas FLT3 mutations had no ...

Among patients with good prognosis core binding factor AML, there is an overall survival rate of only 44%. To understand the genetic factors contributing to poor outcomes within this subgroup, Dr Chew is analysing bone marrow samples collected from 18 patients before and during treatment.. According to Dr Chew, multiple genetic abnormalities acquired during therapy are probably responsible for good prognosis core binding AML developing resistance to chemotherapy.. "To help us predict who will respond poorly to therapy, were identifying the genetic mutations occurring in patients who relapse," he said. "This information will allow us to tailor patient treatment accordingly. Currently a stem cell transplant is considered the definitive treatment and our findings will help clinicians decide if their patients AML will develop resistance and if a stem cell transplant is recommended.". Dr Chew is testing the usefulness of the genetic variations he identifies through an international ...

PHF2라는 단백질이 뼈를 만드는 세포(조골세포)를 활성화시킨다는 사실을 처음으로 규명했다. 조골세포는 Runx2라는 단백질에 의해 분화가 조절된다. 반면, SUV39HI1라는 효소는 Runx2에 메틸기(CH3)를 붙임으로써 Runx2가 기능을 하지 못하게 하는 장식으로 분화를 방해한다. 성장이 끝난 성인들이 더 이상 키가 크지 않는 것도 SUV39HI1 효소 때문이다. 이에 착안해 Runx2에 붙어 있는 메틸기를 제거하는 방안을 연구한 결과, PHF2 단백질이 조골세포 분화를 유도함으로써, 소아의 뼈 발달 과정이나 골절 후 뼈가 새로 형성되는 과정에 작용한다는 것을 증명했다..

Decreased Llgl1 expression has been previously shown to be associated with increased metastatic potential, malignant phenotype, or inferior survival in a variety of solid tumors (Ohali et al., 2004; Schimanski et al., 2005; Kuphal et al., 2006). Given that Llgl1 restrains self-renewal in HSCs and that leukemia is characterized by aberrant activation of self-renewal, we assessed for a role in human AML. First, we asked whether the gene expression signature revealed by genetic inactivation of Llgl1 (Llgl1−/− signature) in HSCs was associated with any genetic subtypes of primary AML. Indeed, clustering based on the Llgl1−/− signature (Fig. 4 B) grouped AML cases into subgroups significantly associated with cytogenetic abnormalities (Fig. 4, B and C). Especially core-binding factor leukemias (t(8;21) and inv(16)) or t(15;17) clustered into specific subgroups. Moreover, the Llgl1−/− signature was most strongly correlated with group 7 based on hierarchical clustering. This group contained ...
Estrogen receptor α (ER α) and androgen receptor (AR) are master transcription factors in the breast and prostate, respectively. They are commonly known in development of sexual characteristics. However, both ERα and AR have been known to be involved in breast cancer (BCa) and prostate cancer (PCa) progression, respectively. The Runx family of transcription factors plays a role in hematopoiesis (Runx1), skeletogenesis (Runx2) and neurogenesis (Runx3). In addition, Runx proteins inhibit cell cycle progression, and have been assigned tumor suppressor roles in various contexts. Because both BCa and PCa cells metastasize to bone at high frequency, investigators have interrogated the possibility that they share characteristics with osteoblasts. Indeed, BCa and PCa cells were found to have "osteomimetic" properties, including expression of Runx2 and Runx2-target genes otherwise expressed by osteoblasts. Provoked by the reported physical interaction between AR and Runx2, we initiated a study to test ...

To study the effects and importance of fluoride on FBs in the development of extraperiosteal calcification and the ossification of skeletal fluorosis, the presence of the osteogenic phenotype, which is indicated by the expression of core-binding factor a1 (Cbfa1) and osteocalcin (OCN), in an FB cell line (L929) and in osteoblasts (OBs) exposed to fluoride was determined. Fibroblasts and osteoblasts were exposed to different concentrations of fluoride (0, 0.0001, 0.001, 0.1, 1.0, 10.0 and 20.0mg/L F-). By using RT-PCR and ELISA, the mRNA levels of Cbfa1 and OCN were measured at 48h, and the protein levels of Cbfa1 and OCN were measured at 2, 4, 24, 48 and 72h. The data demonstrated the following: (1) The Cbfa1 protein level in fluoride-treated fibroblasts clearly increased at 48h in the groups treated with 0.0001, 0.001, 0.1, 1.0 and 20.0mg/L F-. The Cbfa1 protein level of the group treated with 10mg/L F- at 72h was higher than that of the control group. The level of Cbfa1 mRNA in the fibroblasts ...
The Runt related transcription factors (RUNX) are recognized as key players in suppressing or promoting tumor growth. RUNX3, a member of this family, is known as a tumor suppressor in many types of cancers, although such a paradigm was challenged by some researchers. The TGF-β pathway governs major upstream signals to activate RUNX3. RUNX3 protein consists of several regions and domains. The Runt domain is a conserved DNA binding domain and is considered as the main part of RUNX proteins since. Herein, we compared the effects of Runt domains and full-Runx3 in cell viability by designing two constructs of Runx3, including N-terminal region and Runt domain. We investigated the effect of full-Runx3, N-t, and RD on growth inhibition in AGS, MCF-7, A549, and HEK293 cell lines which are different in TGF-β sensitivity, in the absence and presence of TGF-β. The full length RUNX3 did not notably inhibit growth of these cell lines while, the N-t and RD truncates showed different trends in these cell lines.
A series of studies of f-electron systems based on density functional theory methods have been performed. The focus of the studies has been on magnetic and structural properties, as well as investigating ways to handle strong electron correlation in these systems.. A version of the self-interaction correction (SIC) method has been developed for a full-potential linear muffin-tin orbital method. The method is demonstrated to have the strong capabilities of previous SIC implementations, to study energetics and phase stabilities of d- and f-electron systems with localisation-delocalisation transitions, but with no geometrical constraints from the underlying band structure method. The method is applied to the high-TC superconductor CeOFeAs, in which the f-shell of the Ce atoms is argued to undergo a Mott transition to a delocalised state under pressure.. The non-collinear magnetic structures of two rare earth compounds, TbNi5 and CeRhIn5 have been studied, and in both cases the complex magnetic ...
The novel FMS-like tyrosine kinase 3 (FLT3)-N676K point mutation within the FLT3 kinase domain-1 was recently identified in 6 % of de novo acute myeloid leukemia (AML) patients with inv(16). Because FLT3-N676K was encountered almost exclusively in inv(16) AML, we investigated the transforming potential of FLT3-N676K, the cooperation between FLT3-N676K and core binding factor ß-smooth muscle myosin heavy chain (CBFß-SMMHC) (encoded by the inv(16) chimeric gene CBFB-MYH11) in inducing acute leukemia, and tested the sensitivity of FLT3-N676K-positive leukemic cells to FLT3 inhibitors. Retroviral expression of FLT3-N676K in myeloid 32D cells induced AML in syngeneic C3H/HeJ mice (n = 11/13, median latency 58 days), with a transforming activity similar to FLT3-internal tandem duplication (ITD) (n = 8/8), FLT3-TKD D835Y (n = 8/9), and FLT3-ITD-N676K (n = 9/9) mutations. Three out of 14 (21.4 %) C57BL/6J mice transplanted with FLT3-N676K-transduced primary hematopoietic progenitor cells developed ...

The pathogenesis of PDAC involves genetic alterations, such as K-ras protooncogene mutations, mutations of the p53, p16, and Smad4 tumour suppressor genes, and other less common mutations.2 In addition, there are numerous epigenetic alterations, including altered expression of several growth factors and their receptors.3 For example, PDACs overexpress all TGFβ isoforms and their receptors, and overexpression of these ligands and receptors is often associated with shortened postoperative survival of patients with pancreatic cancer.14,15. The TGFβ pathway is carefully regulated, with Smad proteins as the key component in the signal transduction pathway. In addition, other regulators, such as transcription factors, which facilitate Smad binding to target promoters, may provide routes for feedback and crosstalk.16 For example, members of the CBFA (core binding factor A) family of transcription factors act both as targets and partners of activated Smads. This family, also termed the "Runx family", ...

Runx1 mediates the development of the granular convoluted tubules in the submandibular glands[1] "The mouse granular convoluted tubules (GCTs), which are only located in the submandibular gland (SMG) are known to develop and maintain their structure in an androgen-dependent manner. We previously demonstrated that the GCTs are involuted by the epithelial deletion of core binding factor β (CBFβ), a transcription factor that physically interacts with any of the Runt-related transcription factor (RUNX) proteins (RUNX1, 2 and 3). This result clearly demonstrates that the Runx /Cbfb signaling pathway is indispensable in the development of the GCTs. However, it is not clear which of the RUNX proteins plays useful role in the development of the GCTs by activating the Runx /Cbfb signaling pathway. Past studies have revealed that the Runx /Cbfb signaling pathway plays important roles in various aspects of development and homeostatic events. Moreover, the Runx genes have different temporospatial ...
