Group B of the Sox transcription factor family is crucial in embryo development in the insects and vertebrates. Sox group B, unlike the other Sox groups, has an unusually enlarged functional repertoire in insects, but the timing and mechanism of the expansion of this group were unclear. We collected and analyzed data for Sox group B from 36 species of 12 phyla representing the major metazoan cl...
Group B Sox genes, Sox1, -2 and -3 are known to activate crystallin genes and to be involved in differentiation of lens and neural tissues. Screening of chicken genomic sequences for more Group B Sox genes identified two additional genes, Sox14 and Sox21. Proteins encoded by Sox14 and Sox21 genes are similar to each other but distinct from those coded by Sox1-3 (subgroup B1) except for the HMG ...
AIMS AND BACKGROUND This study was designed to compare the efficacy and safety of paclitaxel/oxaliplatin/fluorouracil (TOF) regimen and S-1/oxaliplatin (SOX) regimen for metastatic gastric cancer (GC) patients. METHODS Sixty patients were divided into TOF group and SOX groups randomly. Patients in the TOF group received paclitaxel (135 mg/m2 iv) on day 1, oxaliplatin (100 mg/m2 iv) on day 1, ...
The Sox transcription factor family is characterized with the presence of a Sry-related high-mobility group (HMG) box and plays important roles in various biological processes in animals, including sex determination and differentiation, and the development of multiple organs. In this study, 27 Sox genes were identified in the genome of the Nile tilapia (Oreochromis niloticus), and were classifi...
یکی از اساسی ترین معضلات زیست محیطی پالایشگاه های نفت کشور، آلودگی هواست. این پالایشگاه ها با انتشار انواع آلاینده های گازی نظیر sox ، pm، cox، hc، nox، h2s و... سهم قابل توجهی در ایجاد آلودگی هوای شهر و محیط اطراف خود دارند، لذا، ضرورت این تحقیق احساس می شود . در این مطالعه، مهمترین آلاینده های هوای (co -(nox - sox منتشر شده از پالایشگاه نفت شیراز طی 6 ماه نمونه برداری مستمر و در شعاع ٢5 ...
B1 SOX Coordinate Cell Specification with Patterning and Morphogenesis in the Early Zebrafish Embryo
The B1 SOX transcription factors SOX1/2/3/19 have been implicated in various processes of early embryogenesis. However, their regulatory functions in stages from the blastula to early neurula remain largely unknown, primarily because loss-of-function studies have not been informative to date. In our present study, we systematically knocked down the B1 sox genes in zebrafish. Only the quadruple ...
BACKGROUND We evaluated the efficacy and safety of S-1 plus oxaliplatin (SOX) as an alternative to cisplatin plus S-1 (CS) in first-line chemotherapy for advanced gastric cancer (AGC). PATIENTS AND METHODS In this randomized, open-label, multicenter phase III study, patients were randomly assigned to receive SOX (80-120 mg/day S-1 for 2 weeks with 100 mg/m(2) oxaliplatin on day 1, every 3 wee...
The Sox pathway found in many sulfur bacteria oxidizes thiosulfate to sulfate. Pathway intermediates are covalently bound to a cysteine residue in the carrier protein SoxYZ. We have used biochemical complementation by SoxYZ-conjugates to probe the identity of the intermediates in the Sox pathway. We find that unconjugated SoxYZ and SoxYZ-S-sulfonate are unlikely to be intermediates during norma...
It is now recognized that several rounds of whole genome duplication (WGD) have occurred during the evolution of vertebrates, but the link between WGDs and phenotypic diversification remains unsolved. We have investigated in this study the impact of the teleost-specific WGD on the evolution of the sox gene family in teleostean fishes. The sox gene family, which encodes for transcription factors...
