The unicellular eukaryote Entamoeba histolytica is a human parasite that causes amebic dysentery and liver abscess. A genome-wide analysis of gene expression modulated by intestinal colonization and invasion identified an upregulated transcript that encoded a putative high-mobility-group box (HMGB) protein, EhHMGB1. We tested if EhHMGB1 encoded a functional HMGB protein and determined its role ...
In plants, the chromatin-associated high mobility group (HMG) proteins occur in two subfamilies termed HMGA and HMGB. The HMGA proteins are characterized by the presence of four AT-hook DNA binding motifs, and the HMGB proteins contain an HMG box DNA binding domain. As architectural factors, the HMG proteins appear to be involved in the regulation of transcription and other DNA-dependent proces...
High-mobility group B (HMGB) proteins bind duplex DNA without sequence specificity, facilitating the formation of compact nucleoprotein structures by increasing the apparent flexibility of DNA through the introduction of DNA kinks. It has remained unclear whether HMGB binding and DNA kinking are simultaneous and whether the induced kink is rigid (static) or flexible. The detailed molecular mech...
Cells grow in response to nutrients or growth factors, whose presence is detected and communicated by elaborate signaling pathways. Protein kinases play crucial roles in processes such as cell cycle progression and gene expression, and misregulation of such pathways has been correlated with various diseased states. Signals intended to promote cell growth converge on ribosome biogenesis, as the ...
The mosquito Aedes aegypti can spread the dengue, chikungunya and yellow fever viruses. Thus, the search for key molecules involved in the mosquito survival represents today a promising vector control strategy. High Mobility Group Box (HMGB) proteins are essential nuclear factors that maintain the high-order structure of chromatin, keeping eukaryotic cells viable. Outside the nucleus, secreted ...
High mobility group box‑1 (HMGB‑1) has been reported to serve significant roles in various inflammatory diseases. However, the correlation between the circulating level of HMGB‑1 and severity of community‑acquired pneumonia (CAP) remains unclear. The present study investigated differential alterations in plasma HMGB‑1 levels of patients with CAP prior to and following antibiotic treatment, and ...
