BACKGROUND: Runx transcription factors play critical roles in the developmental control of cell fate and contribute variously as oncoproteins and tumor suppressors to leukemia and other cancers. To discover fundamental Runx functions in the cell biology of animal development, we have employed morpholino antisense-mediated knockdown of the sea urchin Runx protein SpRunt-1. Previously we showed that embryos depleted of SpRunt-1 arrest development at early gastrula stage and underexpress the conventional protein kinase C SpPKC1. RESULTS: We report here that SpRunt-1 deficiency leads to ectopic cell proliferation and extensive apoptosis. Suppression of the apoptosis by pharmacological inhibition of caspase-3 prevents the ectopic proliferation and rescues gastrulation, indicating that many of the overt defects obtained by knockdown of SpRunt-1 are secondary to the apoptosis. Inhibition or knockdown of SpPKC1 also causes apoptosis, while cell survival is rescued in SpRunt-1 morphant embryos coinjected with

The mechanism underlying the lineage decision made by CD4(+)CD8(+) double-positive (DP) thymocytes that give rise to two T lymphocyte subset with distinct functionalities, that is, helper and cytotoxic T cells, remains a major issue in immunology. The lineage decision process involves several phases and terminates when cells loose their developmental plasticity to become the alternate lineage. A detailed picture of the transcription factor network governing helper versus cytotoxic-lineage decision has recently emerged. Studies published only past year provided new insights into how the expression of ThPOK, a central transcription factor for helper T cell development, is regulated. It has now become evident that an antagonistic interplay between ThPOK and Runx transcription factor complexes plays an essential role in thwarting an alternate fate during the commitment process.
Cell proliferation. To assess cell proliferation, 1 × 105 cells of the indicated AML-derived cells were seeded in 6-well plates. For the tetracycline-inducible gene or shRNA expression, doxycycline was added to the culture at a final concentration of 3 μM. Trypan blue dye exclusion assays were performed every other day.. RT-qPCR. Total RNA was isolated with an RNeasy Mini Kit (Qiagen) and reverse transcribed with a ReverTra Ace kit (TOYOBO) to generate cDNA. RT-qPCR was carried out with a 7500 Real-Time PCR System (Applied Biosystems) according to the manufacturers instructions. The results were normalized to GAPDH levels. Relative expression levels were calculated using the 2-ΔΔCt method. Primers used for RT-qPCR are listed in Supplemental Table 3.. ChIP-qPCR. ChIP was performed using a SimpleChIP Plus Enzymatic Chromatin IP Kit (Cell Signaling Technology) according to the manufacturers instructions. In brief, cells were cross-linked in 1% formaldehyde in PBS for 10 minutes at room ...

core binding factor alpha: core binding factor plays a key role in several development pathways and in human disease; has been sequenced
Runt-related transcription factor 1 (RUNX1) is generally considered to function as a tumor suppressor in the development of leukemia, but a growing body of evidence suggests that it has pro-oncogenic properties in acute myeloid leukemia (AML). Here we have demonstrated that the antileukemic effect mediated by RUNX1 depletion is highly dependent on a functional p53-mediated cell death pathway. Increased expression of other RUNX family members, including RUNX2 and RUNX3, compensated for the antitumor effect elicited by RUNX1 silencing, and simultaneous attenuation of all RUNX family members as a cluster led to a much stronger antitumor effect relative to suppression of individual RUNX members. Switching off the RUNX cluster using alkylating agent-conjugated pyrrole-imidazole (PI) polyamides, which were designed to specifically bind to consensus RUNX-binding sequences, was highly effective against AML cells and against several poor-prognosis solid tumors in a xenograft mouse model of AML without ...
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 ...
The Runx family of transcription factors supports cell fate determination, cell cycle regulation, global protein synthesis control, and genetic as well as epigenetic regulation of target genes. Runx1, which is essential for hematopoiesis; Runx2, which is required for osteoblast differentiation; and Runx3, which is involved in neurologic and gut development; are expressed in the growth plate during chondrocyte maturation, and in the chondrocytes of permanent cartilage structures. While Runx2 is known to control genes that contribute to chondrocyte hypertrophy, the functions of Runx1 and Runx3 during chondrogenesis and in cartilage tissue have been less well studied. The goals of this project were to characterize expression of Runx proteins in articular cartilage and differentiating chondrocytes and to determine the contribution of Runx1 to osteoarthritis (OA). Here, the expression pattern of Runx1 and Runx2 was characterized in normal bovine articular cartilage. Runx2 is expressed at higher levels in
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 ...
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.

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 ...
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 ...
Background. Members of the Runx gene family encode transcription factors that bind to DNA in a sequence-specific manner. Among the three Runx proteins, Runx2 comprises 607 amino acid (aa) residues, is expressed in bone, and plays crucial roles in osteoblast differentiation and bone development. We examined whether the Runx2 gene is also expressed in testes. Methods. Murine testes from 1-, 2-, 3-, 4-, and 10-week-old male mice of the C57BL/6J strain and W∕Wv strain were used throughout the study. Northern Blot Analyses were performed using extracts form the murine testes. Sequencing of cDNA clones and 5′-rapid amplification of cDNA ends were performed to determine the full length of the transcripts, which revealed that the testicular Runx2 comprises 106 aa residues coding novel protein. Generating an antiserum using the amino-terminal 15 aa of Runx2 (Met1 to Gly15) as an antigen, immunoblot analyses were performed to detect the predicted polypeptide of 106 aa residues with the initiating Met1.

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 ...

TY - JOUR. T1 - New challenges in integrated diagnosis by imaging and osteo-immunology in bone lesions. AU - Schiano, Concetta. AU - Soricelli, Andrea. AU - de Nigris, Filomena. AU - Napoli, Claudio. PY - 2018/12/20. Y1 - 2018/12/20. N2 - INTRODUCTION: High-resolution imaging is the gold standard to measure the functional and biological features of bone lesions. Imaging markers have allowed the characterization both of tumour heterogeneity and metabolic data. Besides, ongoing studies are evaluating a combined use of "imaging markers", such as SUVs, MATV, TLG, ADC from PET and MRI techniques respectively, and several "biomarkers" spanning from chemokine immune-modulators, such as PD-1, RANK/RANKL, CXCR4/CXCL12 to transcription factors, such as TP53, RB1, MDM2, RUNX family, EZH2, YY1, MAD2. Osteoimmunology may improve diagnosis and prognosis leading to precision medicine in bone lesion treatment. Areas covered: We investigated modalities (molecular and imaging approach) useful to identify bone ...

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 ...

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 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", ...

TY - JOUR. T1 - HDAC1 is a required cofactor of CBFb-SMMHC and a potential therapeutic target in inversion 16 acute myeloid leukemia. AU - Richter, Lisa E.. AU - Wang, Yiqian. AU - Becker, Michelle E.. AU - Coburn, Rachel A.. AU - Williams, Jacob T.. AU - Amador, Catalina. AU - Hyde, R. Katherine. PY - 2019/6/1. Y1 - 2019/6/1. N2 - Acute myeloid leukemia (AML) is a neoplastic disease characterized by the uncontrolled proliferation and accumulation of immature myeloid cells. A common mutation in AML is the inversion of chromosome 16 [inv (16)], which generates a fusion between the genes for core binding factor beta (CBFB) and smooth muscle myosin heavy chain gene (MYH11), forming the oncogene CBFB-MYH11. The expressed protein, CBFb-SMMHC, forms a heterodimer with the key hematopoietic transcription factor RUNX1. Although CBFb-SMMHC was previously thought to dominantly repress RUNX1, recent work suggests that CBFb-SMMHC functions together with RUNX1 to activate transcription of specific target ...
Runt-related transcription factor 1 (RUNX1) is a heterodimeric transcription factor that binds to the core element of many enhancers and promoters and can accelerate apoptosis in various tumors. However, the regulatory mechanisms underlying RUNX1 expression in neuroblastoma (NB), a highly malignant tumor in childhood, remain largely unclear. In this study, we aimed to assess the role of RUNX1 in NB and to reveal the underlying mechanisms that may contribute to finding a potential therapeutics strategy against NB. Growth, invasion, metastasis and angiogenesis were assessed using Cell Counting Kit-8 (CCK-8) immunocytochemistry, and studies involving soft agar, cell invasion, tube formation and whole animals. The levels of expression were measured using real-time quantitative PCR for RNA, Western blot and immunostaining analyses for proteins. Luciferase reporter and chromatin immunoprecipitation assays indicated that RUNX1 directly binds within the BIRC5, CSF2RB and NFKBIA promoter regions to facilitate

A temperature compensation circuit arrangement for liquid crystal cells in optical devices is presented. In an optical device, a liquid crystal cell typically manipulates the optical signals according to an output optical property, such as attenuation, responsive to an AC voltage source electrical signal. A feedback circuit arrangement is connected to the liquid crystal cell and controls the current through the liquid crystal cell with respect to temperature by a predetermined control equations for the output optical property so that the device manipulates the optical signals independently of temperature. The current follows the control equations, which are empirically determined with respect to temperature for one equation.
