Influence of -Regulated Expression on Lung Adenocarcinoma Proliferation.

Objective Aberrant expression of ATP binding cassette subfamily B member 1 () plays a key role in several cancers. However, influence of G protein coupled receptor family C group 5 type A (GPRC5A)-regulated expression on lung adenocarcinoma proliferation remains unclear. Therefore, this study investigated the effect of regulated expression on the proliferation of lung adenocarcinoma.

Differential mRNA Expressions in HCMV infected HUVECs.

Objective: The aim was to identify the gene expressions of human cytomegalovirus (HCMV)-infected human umbilical vein endothelial cells (HUVECs) and to study its possible pathogenic mechanism on atherosclerosis using microarray technology.

Methods: The gene expression differences in HCMV AD169 strain-infected HUVECs were studied by the microarray technology to explore the potential molecular mechanism of HCMV infection. The qPCRs were performed to verify the transcriptome results.

A novel methodology of the myeloid-derived suppressor cells (MDSCs) generation with splenic stroma feeder cells.

Myeloid-derived suppressor cells (MDSCs) are a significant obstacle for immunotherapy of cancer. It is of great clinical relevance to study the mechanism of MDSCs accumulation in mouse spleens and establish a stable method to obtain high-purity MDSCs in vitro for further research. Here, we established a new method for amplifying a large number of highly pure MDSCs in vitro.

Cooperative Activity of GABP with PU.1 or C/EBPε Regulates Lamin B Receptor Gene Expression, Implicating Their Roles in Granulocyte Nuclear Maturation.

Nuclear segmentation is a hallmark feature of mammalian neutrophil differentiation, but the mechanisms that control this process are poorly understood. Gene expression in maturing neutrophils requires combinatorial actions of lineage-restricted and more widely expressed transcriptional regulators. Examples include interactions of the widely expressed ETS transcription factor, GA-binding protein (GABP), with the relatively lineage-restricted E-twenty-six (ETS) factor, PU.

Progression of Large Lymphoma Is Significantly Impeded with a Combination of Gemcitabine Chemotherapy and Dendritic Cells Intra-Tumor Vaccination.

Relapsed, refractory lymphoma remains to be a challenge and lacks efficient treatment. Some tumor cells escape from treatment, become resistant to chemotherapeutic agents, and rapidly regenerate into large tumors. Lymphoma cells induce accumulation of Gr-1(+-)CD11b(+) myeloid derived suppressor cells (MDSCs) in lymphatic organs and their vicinity.

Impact on survival of the number of lymph nodes resected in patients with lymph node-negative gastric cancer.

Background: Patients with lymph node-negative gastric cancer show a better overall survival rate than those who have a pathological lymph node-positive gastric cancer. But a large number of patients still develop recurrence. We aimed to explore the significant prognostic factors of lymph node-negative gastric cancer and determine how many lymph nodes should be removed.

Marsdenia tenacssima extract and its functional components inhibits proliferation and induces apoptosis of human Burkitt leukemia/lymphoma cells in vitro and in vivo.

Burkitt lymphoma is a fast growing non-Hodgkin lymphoma that occurs primarily in young males. The causes of Burkitt lymphoma include chromosome rearrangement and virus infection, but accurate and complete reasons remain to be discovered. The available treatment for Burkitt lymphoma is chemotherapy and radiation therapy.

GABP transcription factor (nuclear respiratory factor 2) is required for mitochondrial biogenesis.

Mitochondria are membrane-bound cytoplasmic organelles that serve as the major source of ATP production in eukaryotic cells. GABP (also known as nuclear respiratory factor 2) is a nuclear E26 transformation-specific transcription factor (ETS) that binds and activates mitochondrial genes that are required for electron transport and oxidative phosphorylation. We conditionally deleted Gabpa, the DNA-binding component of this transcription factor complex, from mouse embryonic fibroblasts (MEFs) to examine the role of Gabp in mitochondrial biogenesis, function, and gene expression.

GABP transcription factor is required for development of chronic myelogenous leukemia via its control of PRKD2.

Hematopoietic stem cells (HSCs) are the source of all blood lineages, and HSCs must balance quiescence, self-renewal, and differentiation to meet lifelong needs for blood cell development. Transformation of HSCs by the breakpoint cluster region-ABL tyrosine kinase (BCR-ABL) oncogene causes chronic myelogenous leukemia (CML). The E-twenty six (ets) transcription factor GA binding protein (GABP) is a tetrameric transcription factor complex that contains GABPα and GABPβ proteins.

PU.1 is essential for CD11c expression in CD8(+)/CD8(-) lymphoid and monocyte-derived dendritic cells during GM-CSF or FLT3L-induced differentiation.

Dendritic cells (DCs) regulate innate and acquired immunity through their roles as antigen-presenting cells. Specific subsets of mature DCs, including monocyte-derived and lymphoid-derived DCs, can be distinguished based on distinct immunophenotypes and functional properties. The leukocyte integrin, CD11c, is considered a specific marker for DCs and it is expressed by all DC subsets.

[Determination of translocatable matter of rice by near infrared reflectance spectroscopy].

The potential of predicting translocatable matter of rice with near infrared reflectance spectroscopy (NIRS) was studied. Using 7 varieties of rice planted in Danzhou of Hainan province as materials, the method of neutral detergent fiber added amylase with NIRS was examined to establish calibration model of predicting translocatable matter of stem and panicle of rice. The results indicated that partial least square(PLS1) is the best regression statistic method for calibration model; The differences of results of the spectral data pretreatment methods for calibration model were insignificant; Because of the high prediction accuracy, the final calibration model was chosen using "no spectral data pretreatment" + "PLS1"; Determination coefficient of external validation and root mean square errors of prediction of the calibration model of stem and panicle was 0.

Phospho-SXXE/D motif mediated TNF receptor 1-TRADD death domain complex formation for T cell activation and migration.

In TNF-treated cells, TNFR1, TNFR-associated death domain protein (TRADD), Fas-associated death domain protein, and receptor-interacting protein kinase proteins form the signaling complex via modular interaction within their C-terminal death domains. In this paper, we report that the death domain SXXE/D motifs (i.e.

GABP transcription factor is required for myeloid differentiation, in part, through its control of Gfi-1 expression.

GABP is an ets transcription factor that regulates genes that are required for myeloid differentiation. The tetrameric GABP complex includes GABPα, which binds DNA via its ets domain, and GABPβ, which contains the transcription activation domain. To examine the role of GABP in myeloid differentiation, we generated mice in which Gabpa can be conditionally deleted in hematopoietic tissues.

[A review on the environmental behaviors and toxicity assessment of chromium in soil-plant systems].

As a result of the wide use of chromium (Cr) and its compounds as well as the exposure of the Cr-containing wastes, air, soil, water and food could be polluted by Cr in varying degrees. Cr is a toxic element that occurs in highly variable oxidation states. Accordingly, environmental chromium pollution, especially the soil contamination with Cr, has become one of the focuses of environmental science.

Retinoic acid signaling in myelopoiesis.

Purpose Of Review: For decades, retinoic acid has been known to alter the proliferation and differentiation of myeloid cells. Currently, retinoic acid is a front-line agent in the treatment of certain forms of acute myelogenous leukemia. In this review, we focus on recent advances in our understanding of the mechanisms by which retinoids affect growth and proliferation of myeloid cells and contribute to the pathogenesis of leukemia.

The Ets transcription factor GABP is required for cell-cycle progression.

The transition from cellular quiescence (G0) into S phase is regulated by the mitogenic-activation of D-type cyclins and cyclin-dependent kinases (Cdks), the sequestration of the Cdk inhibitors (CDKIs), p21 and p27, and the hyperphosphorylation of Rb with release of E2F transcription factors. However, fibroblasts that lack all D-type cyclins can still undergo serum-induced proliferation and key E2F targets are expressed at stable levels despite cyclical Rb-E2F activity. Here, we show that serum induces expression of the Ets transcription factor, Gabpalpha, and that its ectopic expression induces quiescent cells to re-enter the cell cycle.

Stat3 cleavage by caspases: impact on full-length Stat3 expression, fragment formation, and transcriptional activity.

Stat3 and its isoforms belong to a family of cytoplasmic transcription factors that affect the synthesis of various proteins. Caspases are cysteinyl-aspartate proteases that function under apoptotic and non-apoptotic conditions. We now report that, in addition to transcriptional splicing, Stat3 fragmentation can be mediated by caspases.
