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...

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...

ammalian sex-determining factors with homology to DNA binding proteins are required for splicing, according to a study by Paolo SassoneCorsi and coworkers at the Université Louis Pasteur (Strasbourg, France). Examination of high mobility group (HMG) domain containing SRY and Sox proteins demonstrated a surprising but clear association with splicing complexes. SRY, the testis-determining factor ...

Gastric carcinoma is a heterogeneous malignant disease involving genetic factors. To identify predictive markers for gastric cancer treatment in Chinese patients, we evaluated the association between polymorphisms of the gene encoding cytochrome P450 2A6 (CYP2A6) and outcomes of S-1 plus oxaliplatin (SOX) chemotherapy treatment. Clinical data on 60 consecutive gastric cancer patients receiving ...

A central question in genomic imprinting is how parental-specific DNA methylation of imprinting control regions (ICR) is established during gametogenesis and maintained after fertilization. At the imprinted Igf2/H19 locus, CTCF binding maintains the unmethylated state of the maternal ICR after the blastocyst stage. In addition, evidence from Beckwith-Wiedemann patients and cultured mouse cells ...

Tight junctions have recently emerged as essential signaling regulators of proliferation and differentiation in epithelial tissues. Here, we aimed to identify the factors regulating claudin-7 expression in the colon, and analyzed the consequences of claudin-7 overexpression in colorectal carcinoma (CRC). In healthy human colonic crypts, claudin-7 expression was found to be low in the stem/proge...

pistachio oil has important nutritional and therapeutic properties because of high concentration of essential fatty acids. the extraction method used to obtain natural compounds from raw matter is critical for product quality and especially protection of nutrition value of them. the study was conducted to compare fatty acid composition of pistachio oil extracted by two conventional procedures: ...

The present study investigated the clinical efficacy of S-1 plus oxaliplatin (SOX) regimen, with or without surgery in α-fetoprotein-producing gastric cancer (APGC) with liver metastasis. A total of 24 patients with APGC treated at the Liaocheng People's Hospital between January 2011 and December 2013 were retrospectively reviewed. Clinical efficacy and patient safety were compared between the ...
