Laparoscopy (LS) has been shown to decrease the inflammatory sequelae of endotoxemia. β-arrestin 2 plays an important function in signal transduction pathway of TLR4. High mobility group box-1 (HMGB-1) is involved in the delayed systemic inflammatory response. We investigated the effects of CO2 insufflation on liver, lung, and kidney expression of both β-arrestin 2 and HMGB-1 during sepsis. Cec...

Aims. To detect the association of C1q/TNF-related protein-3 (CTRP-3) and high-mobility group box-1 (HMGB-1) in subjects with prediabetes (pre-DM) and newly diagnosed type 2 diabetes (nT2DM). Methods. 224 eligible participants were included. The 75 g oral glucose tolerance test (OGTT) and several clinical parameters of metabolic disorders and cytokines were measured. All participants were divid...

High mobility group 2 protein (Hmgb2) is a member of the HMGB protein family, which includes the ubiquitous Hmgb1 and the embryo-specific Hmgb3. The three proteins are more than 80% identical at the amino acid level and their biochemical properties are indistinguishable. Hmgb1 is an abundant component of all mammalian nuclei and acts as an architectural factor that bends DNA and promotes protei...

Ubiquitous high-mobility-group (HMGB) chromosomal proteins bind DNA in a non-sequence- specific fashion to promote chromatin function and gene regulation. Minor groove DNA binding of the HMG domain induces substantial DNA bending toward the major groove, and several interfacial residues contribute by DNA intercalation. The role of the intercalating residues in DNA binding, bending and specifici...

The high mobility group (HMG) proteins constitute a superfamily of nuclear proteins that regulate the expression of a wide range of genes through architectural remodeling of the chromatin structure, and the formation of multiple protein complexes on promoter/enhancer regions, but their function in germ layer specification during early development is not clear. Here we show that hmgb genes regul...

HMGB-like proteins are architectural chromatin factors, and their function is heavily dependent on their ability to interact with DNA (especially non-canonical DNA structures). HMGB1 is involved in many DNA processes, and dysregulation of HMGB protein expression has profound effects on cellular transcription, resulting in severe developmental defects as well as cancer. During DNA replication, e...

Acute kidney injury (AKI) is a severe complication of sepsis. High-mobility group box (HMGB)-1 was implicated as a late mediator of lethal systemic inflammation in sepsis. Since glutamine (GLN) was shown to have anti-inflammatory and antioxidant properties, we hypothesized that GLN administration may downregulate an HMGB-1-mediated pathway and thus ameliorate sepsis-induced AKI. Mice were rando...
