Genes of the Sox family encode evolutionarily conserved HMG box containing transcription factors, which play key roles in various events of cell determination/differentiation during development. The total number of Sox genes in Drosophila melanogaster was estimated to be eight, after classical molecular cloning approaches and exhaustive screening of the complete Drosophila genome. Here we repor...

The Sarbanes-Oxley Act of 2002 (SOX) was established to strengthen internal controls over financial reporting by U.S. public firms and, as a consequence, to increase investor and stakeholder confidence in published financial reports. Among the many SOX provisions, SOX 404 requires an annual assessment by the firm’s executive management and external auditor of the firm’s internal controls over f...

Background: Cis-acting sequences regulate regionspecific DNA demethylation. Results: DNA demethylation of a fragment from the mouse H19/Igf2 imprinted control region requires two Sox-Oct motifs, one of which is methylation sensitive. Conclusion: The Sox-Oct motif functions to induce DNA demethylation in P19 cells. Significance: The Sox-Oct motif might be a key element to induce region-specific ...

The Y chromosomal switch gene SRY, which initiates testis development during mammalian embryogenesis was recently described (l).The SRY-encoded protein contains a 79 amino acid DNA-binding motif referred to as an HMG-box (2) known to exist in other transcription factors or proteins involved in DNA bending (3). On the basis of the homology between their HMGboxes, other SRY-related genes have bee...

Neurogenesis involves deeply conserved patterning molecules, such as the proneural basic helix-loop-helix transcription factors. Sox proteins and specifically members of the SoxB and SoxC groups are anotherclassof conserved transcription factorswithan important role in neuronal fate commitment and differentiation in various species. In this study,we examine the expressionof all fiveSox genes of...

One characteristic of lytic infection with gammaherpesviruses, including Kaposi's sarcoma-associated herpesvirus (KSHV), Epstein-Barr virus (EBV) and murine herpesvirus 68 (MHV68), is the dramatic suppression of cellular gene expression in a process known as host shutoff. The alkaline exonuclease proteins (KSHV SOX, MHV-68 muSOX and EBV BGLF5) have been shown to induce shutoff by destabilizing ...

The aim of this study was to investigate the possible effects of sulphite oxidase (SOX, E.C. 1.8.3.1) deficiency on xenobiotic metabolism. For this purpose, SOX deficiency was produced in rats by the administration of a low molybdenum diet with concurrent addition of 200 ppm tungsten to their drinking water. First, hepatic SOX activity in deficient groups was measured to confirm SOX deficiency....

Sox-5 is one of a family of genes which show homology to the HMG box region of the testis determining gene SRY. We have used indirect immunofluorescence to show that Sox-5 protein is localized to the nucleus of post-meiotic round spermatids in the mouse testis. In vitro footprinting and gel retardation assays demonstrate that Sox-5 binds specifically to the sequence AACAAT with moderately high ...

SOX9 is a transcriptional activator required for chondrogenesis, and SOX5 and SOX6 are closely related DNA-binding proteins that critically enhance its function. We use here genome-wide approaches to gain novel insights into the full spectrum of the target genes and modes of action of this chondrogenic trio. Using the RCS cell line as a faithful model for proliferating/early prehypertrophic gro...
