Abstract Background and Aims Before implementing individualized strategies to prevent or treat acute kidney injury (AKI), identifying clusters of patients with common (or divergent) pathophysiological mechanisms, diagnosis criteria outcome is upmost importance. Method We compared the characteristics 1170 male female referred for cardiac surgery bypass (CBP) using multivariate logistic regressio...

Poxviruses encode a variety of immunomodulatory proteins that subvert the cytokine networks of infected hosts. Myxoma virus, a poxvirus pathogen of rabbits, expresses two distinct 35- to 40-kDa secreted glycoproteins that bind a broad spectrum of chemokines. The first of these, designated M-T7, is encoded by the T7 gene and is the first example of what is here referred to as type-I chemokine bi...

Transcriptional regulation of the steroidogenic acute regulatory (StAR) protein gene by cAMP-dependent mechanisms occurs in the absence of a consensus cAMP-response element (CRE; TGACGTCA) and is mediated by several sequence-specific transcription factors. We previously identified three CRE-like sites (within the -151/-1 bp cAMP-responsive region of the mouse StAR gene), of which the CRE2 site ...

Tax, the transforming protein of human T-cell leukemia virus type 1 (HTLV-1), is required for strong activation of HTLV-1 transcription. This activation is mediated through interaction with the KIX domain of the cellular coactivator CREB binding protein (CBP). In this study we examined the possibility that the Tax-KIX interaction may mediate effects on cellular gene transcription in vivo, as a ...

Autism spectrum disorders (ASDs) are a group of neurodevelopmental afflictions characterized by repetitive behaviors, deficits in social interaction, and impaired communication skills. For most ASD patients, the underlying causes are unknown. Genetic mutations have been identified in about 25 percent of ASD cases, including mutations in epigenetic regulators, suggesting that dysregulated chroma...

Rod and cone photoreceptor neurons in the mammalian retina possess specialized cellular architecture and functional features for converting light to a neuronal signal. Establishing and maintaining these characteristics requires appropriate expression of a specific set of genes, which is tightly regulated by a network of photoreceptor transcription factors centered on the cone-rod homeobox prote...

The class II transactivator (CIITA), the master regulator of the tissue-specific and interferon gamma-inducible expression of major histocompatibility complex class II genes, synergizes with the histone acetylase coactivator CBP to activate gene transcription. Here we demonstrate that in addition to CBP, PCAF binds to CIITA both in vivo and in vitro and enhances CIITA-dependent transcriptional ...

Special AT-rich binding protein 1 (SATB1) nuclear protein, expressed predominantly in T cells, regulates genes through targeting chromatin remodeling during T-cell maturation. Here we show SATB1 family protein induction during early human adult erythroid progenitor cell differentiation concomitant with epsilon-globin expression. Erythroid differentiation of human erythroleukemia K562 cells by h...

Gene therapy of genetic diseases requires persistent and position-independent expression of a therapeutic transgene. Transcriptional enhancers binding chromatin-remodeling and modifying complexes may play a role in shielding transgenes from repressive chromatin effects. We tested the activity of the HS2 enhancer of the GATA1 gene in protecting the expression of a β-globin minigene delivered by ...

The pituitary-specific transcription factor, Pit-1, is necessary to mediate protein kinase A (PKA) regulation of the GH, PRL, and TSH-beta subunit genes in the pituitary. Since these target genes lack classical cAMP DNA response elements (CREs), the mechanism of this regulation was previously unknown. We show that CREB binding protein (CBP), through two cysteine-histidine rich domains (C/H1 and...
