The transcription factor (TF) C/EBPα is essential for myeloid differentiation and is frequently dysregulated in acute myeloid leukemia (AML). While studied extensively, the precise regulation of its gene by upstream factors has remained largely elusive. Here, we investigated its transcriptional activation during myeloid differentiation. We identified an evolutionarily conserved octameric sequence, CCCAGCAG, approximately 100 bases upstream of the CEBPA transcription start site (TSS), and demonstrated through mutational analysis that this sequence is crucial for C/EBPα expression...

The CCAAT/enhancer binding protein (C/EBP) alpha (CEBPA) and Runt-related transcription factor 1 (RUNX1) genes have been traditionally regarded as two essential genes involved in normal myeloid maturation. Although the link between mutations in these genes and the development of acute myeloid leukemia (AML) has been extensively documented, the ramifications of gene expression dysregulations of CEBPA and RUNX1 has drawn less attention. The present study investigated CEBPA and RUNX1 gene expression levels in 96 primary AML specimens against a normal control group by way of real-time RT-PCR...

BACKGROUND/AIM: Liver kinase B1 (LKB1) is a major activator of the AMP-dependent kinase/mammalian target of rapamycin pathway. The prevalence and the specificity of LKB1 gene mutation in acute myeloid leukemia (AML) have not been well established. This study aimed to examine mutation of LKB1 in AML and its clinical and pathological implications. PATIENTS AND METHODS: Eighty-five patients newly diagnosed with cytogenetically normal AML were analyzed using polymerase chain reaction followed by direct sequencing...

Small activating RNAs (saRNAs) are short double-stranded oligonucleotides that selectively increase gene transcription. Here, we describe the development of an saRNA that upregulates the transcription factor CCATT/enhancer binding protein alpha (CEBPA), investigate its mode of action, and describe its development into a clinical candidate. A bioinformatically directed nucleotide walk around the CEBPA gene identified an saRNA sequence that upregulates CEBPA mRNA 2.5-fold in human hepatocellular carcinoma cells...

BACKGROUND: Cytogenetic aberrations and gene mutations have long been regarded as independent prognostic markers in AML, both of which can lead to misexpression of some key genes related to hematopoiesis. It is believed that the expression level of the key genes is associated with the treatment outcome of AML. METHODS: In this study, we analyzed the clinical features and molecular aberrations of 560 newly diagnosed non-M3 AML patients, including mutational status of CEBPA, NPM1, FLT3, C-KIT, NRAS, WT1, DNMT3A, MLL-PTD and IDH1/2, as well as expression levels of MECOM, ERG, GATA2, WT1, BAALC, MEIS1 and SPI1...

Mechanical loading is necessary for the development and maintenance of the musculoskeletal system. Removal of loading via microgravity, paralysis, or bed rest leads to rapid loss of muscle mass and function; however, the molecular mechanisms that lead to these changes are largely unknown, particularly for the spaceflight (SF) microgravity environment. Furthermore, few studies have explored these effects on the shoulder, a dynamically stabilized joint with a large range of motion; therefore, we examined the effects of microgravity on mouse shoulder muscles for the 15-d Space Transportation System (STS)-131, 13-d STS-135, and 30-d Bion-M1 missions...

The cellular environment of the mammalian heart constantly is challenged with environmental and intrinsic pathological insults, which affect the proper folding of proteins in heart failure. The effects of damaged or misfolded proteins on the cell can be profound and result in a process termed "proteotoxicity". While proteotoxicity is best known for its role in mediating the pathogenesis of neurodegenerative diseases such as Alzheimer's disease, its role in human heart failure also has been recognized. The UPR involves three branches, including PERK, ATF6, and IRE1...

Suppressor of cytokine signaling 1 (SOCS1) protein, which encodes a member of signal transducers and activators of transcription-induced inhibitors, takes part in a negative regulation of cytokine signaling. The mechanism of SOCS1 in tumor carcinogenesis is complex and there have been no studies concerning the clinic-biologic implication of SOCS1 expression in acute myeloid leukemia (AML). Here, we first identified that higher bone marrow (BM) SOCS1 expression was closely associated with older age, FLT3-ITD, NPM1 and DNMT3A mutations, but negatively correlated with CEBPA mutation in patients with de novo AML...

This study aimed to analyze the effects of the initial MLL-partial tandem duplication (PTD) expression levels on clinical outcomes in 36 MLL-PTD-positive acute myeloid leukemia (AML) patients between 2014 and 2016. ROC curves showed 1.0% MLL-PTD as the optimal diagnostic cutoff for complete remission (CR). Nineteen and 17 cases had MLL-PTD <1.0% (low-level group) and ≥1.0% (high-level group), respectively. The FAB type distribution (M2 incidence, 100% vs. 53%, p = .003) and double-CEBPA-mutation incidence (37% vs...

The TRIB1 locus has been linked to both cardiovascular disease and hepatic steatosis. Recent efforts have revealed TRIB1 to be a major regulator of liver function, largely, but not exclusively, via CEBPA degradation. We recently uncovered a functional interaction between TRIB1 and HNF4A, another key regulator of hepatic function, whose molecular underpinnings remained to be clarified. Here we have extended these findings. In hepatoma models, HNF4A levels were found to depend on TRIB1, independently of its impact on CEBPA...

Myeloproliferative neoplasms (MPNs) operationally include essential thrombocythemia, polycythemia vera, primary myelofibrosis (PMF), and prefibrotic PMF. All 4 MPN variants might progress into blast-phase disease (MPN-BP). For essential thrombocythemia, reported risk factors for leukemic transformation include advanced age, extreme thrombocytosis, anemia, leukocytosis, and sequence variants/mutations involving TP53 and EZH2 (for expansion of gene symbols, see www.genenames.org); for polycythemia vera, advanced age, leukocytosis, abnormal karyotype, mutations involving SRSF2 and IDH2, and treatment with pipobroman, chlorambucil, or P32; and for PMF, increased blast percentage, thrombocytopenia, abnormal karyotype, triple-negative driver mutational status, and sequence variants/mutations involving SRSF2, RUNX1, CEBPA, and SH2B3...

Tumor suppressor genes (TSGs) and oncogenes (OG) are involved in carcinogenesis. MiRNAs also contribute to cellular pathways leading to cancer. We use data from 217 colorectal cancer (CRC) cases to evaluate differences in TSGs and OGs expression between paired CRC and normal mucosa and evaluate how TSGs and OGs are associated with miRNAs. Gene expression data from RNA-Seq and miRNA expression data from Agilent Human miRNA Microarray V19.0 were used. We focus on genes most strongly associated with CRC (fold change (FC) of ≥1...

Anatomical site and divergent functionalities of muscles can be related to differences in IMF content, metabolism and adipogenic gene expression. Then, potential differences in different muscles in beef cattle were studied. As a second objective, the main sources of experimental variability associated to RT-qPCR results were analyzed following a nested design in order to implement appropriate experimental designs minimizing gene expression variability. To perform the study Longissimus thoracis (LT), Semitendinosus (SM), Masseter (MS), Sternomandibularis (ST) and subcutaneous adipose tissue (SAT) samples of Pirenaica young bulls (n = 4) were collected for IMF, collagen and protein quantification, analysis of adipocyte size distribution and gene expression (PPARG, CEBPA, FAPB4 and WNT10B)...

Transcription factor C/EBPα is a master regulator of myelopoiesis and its inactivation is associated with acute myeloid leukemia. Deregulation of C/EBPα by microRNAs during granulopoiesis or acute myeloid leukemia development has not been studied. Here we show that oncogenic miR-182 is a strong regulator of C/EBPα. Moreover, we identify a regulatory loop between C/EBPα and miR-182. While C/EBPα blocks miR-182 expression by direct promoter binding during myeloid differentiation, enforced expression of miR-182 reduces C/EBPα protein level and impairs granulopoiesis in vitro and in vivo...

Familial CEBPA-mutated acute myeloid leukemia (AML) represents a recognized leukemia predisposition syndrome, with several families described in the literature since the initial report in 2004. The pathological features and long-term survival of individuals with familial CEBPA-mutated AML are reminiscent of sporadic CEBPAdm AML.  Germline mutations predominantly localize to the N-terminal and are associated with near complete penetrance, with age of AML onset from 2-50 years, frequently accompanied by the acquisition of a second CEBPA mutation in C-terminal domain...

Accumulating evidence has shown that long noncoding RNAs (lncRNAs) are significant regulators of multiple cellular processes, including the development of chronic myelocytic leukemia (CML). However, the mechanism of how the lncRNA PLIN2 affects CML development remains unclear. In this study, we aimed to investigate the potential roles of CEBPA-mediated upregulation of PLIN2 in the process of CML development by regulating the GSK3 and Wnt/β-catenin signaling pathways. We found that both CEBPA and PLIN2 were expressed at significantly higher levels in CML...
