HMGB1 is associated with human cancers and is an activator of autophagy which mediates chemotherapy resistance. We here show that the mRNA levels of HMGB1 are high in leukemia cells and it is involved in the progression of childhood chronic myeloid leukemia (CML). HMGB1 decreases the sensitivity of human myeloid leukemia cells K562 to anti-cancer drug(More)
We have cloned a novel KRAB-related zinc finger gene, ZNF307, encoding a protein of 545aa. ZNF307 is conserved across species in evolution and is differentially expressed in human adult and fetal tissues. The fusion protein of EGFP-ZNF307 localizes in the nucleus. Transcriptional activity assays show ZNF307 suppresses transcriptional activity of(More)
The Rho family of small GTPases, including Rho, Rac, and Cdc42, play essential roles in diverse cellular functions. The ability of Rho family GTPases to participate in signaling events is determined by the ratio of inactive (GDP-bound) and active (GTP-bound) forms in the cell. The activation of Rho family proteins requires the exchange of bound GDP for GTP,(More)
Kisspeptins are natural ligands of G protein-coupled receptor-54. Activation of KiSS1/G protein-coupled receptor-54 signaling pathways results in potent activation of the hypothalamus-pituitary-gonadal axis and initiates puberty. Recent data have shown that in female mice, KiSS1 is positively regulated by estradiol (E(2)) in the anteroventral(More)
WD40 repeat proteins play important roles in a variety of cellular functions, including cell growth, proliferation, apoptosis, and intracellular signal transduction. Mitogen-activated protein kinases (MAPKs) are evolutionary conserved enzymes in cell signal transduction connecting cell-surface receptors to critical regulatory targets within cells and(More)
The Drosophila heart has proven itself to be an excellent model for human cardiac development and recent investigations suggest that it may serve as a model for human heart function as well. Just as tinman-related genes underlie cardiac development in all organisms with a heart, the functional properties of mature hearts also appear to be conserved in the(More)
Zinc finger transcription factors are involved broadly in development and tumorigenesis. Here, we report that the little studied zinc finger transcription factor ZNF382 functions as a tumor suppressor in multiple carcinomas. Although broadly expressed in normal tissues, ZNF382 expression was attenuated in multiple carcinoma cell lines due to promoter CpG(More)
Transcription factors play an essential role in altering gene expression. Much progress about transcription factors has been made toward the understanding of normal physiological processes, embryonic development, and human diseases. In the present study, we report the identification and characterization of a novel human gene, (Drosophila) intersex-like(More)
SMYD1 is a heart and muscle specific SET-MYND domain containing protein, which functions as a histone methyltransferase and regulates downstream gene transcription. We demonstrated that the expression of SMYD1 is restricted in the heart and skeletal muscle tissues in human. To reveal the regulatory mechanisms of SMYD1 expression during myogenesis and(More)
Protein phosphatase magnesium-dependent 1A (PPM1A), a protein serine/threonine phosphatase, controls several signal pathways through cleavage of phosphate from its substrates. However, the in vivo function of Ppm1a in mammals remains unknown. Here we reported that mice lacking Ppm1a developed normally but were impaired in re-epithelialization process during(More)
