Sex determination in all mammals is initiated by the Sry locus on the Y chromosome. Sry is a member of the large Sox HMG gene family postulated to have evolved from an ancestor of its paralogue on the Y chromosome, Sox3. This study investigates the relationship of Sry to the Sox genes of other animals, rooted against the HMG protein genes of a number of protists. It also looks at the evolution ...
OBJECTIVE While the developmental role of the SOX transcription factors in fetal chondrocyte differentiation is well documented, much less is known about the expression of SOX family members in normal and osteoarthritic adult cartilage. Therefore, the aim of the present study was to present a thorough analysis of SOX gene expression in normal and osteoarthritic human adult cartilage. METHODS ...
Onset of the lytic phase in the KSHV life cycle is accompanied by the rapid, global degradation of host (and viral) mRNA transcripts in a process termed host shutoff. Key to this destruction is the virally encoded alkaline exonuclease SOX. While SOX has been shown to possess an intrinsic RNase activity and a potential consensus sequence for endonucleolytic cleavage identified, the structures of...
Sox factors transcriptionally regulate ROBO4 gene expression in developing vasculature in zebrafish.
Despite their importance as members of the Roundabout (Robo) family in the control of axonal and vascular patterning, the transcriptional regulation of these genes is poorly understood. In this study, we show that members of the Sry-related high mobility box (Sox) transcription factor family as being transcriptional regulators of roundabout4 (robo4), a Robo gene family member that participates ...
The nucleocytoplasmic shuttling of SOX transcription factors play a crucial role in the regulation of SOX protein functions during development. In this study, we have demonstrated two nuclear localization signals in the HMG box of Eriocheir sinensis SOX14A and SOX14B. These two conserved nuclear localization signals mediate nuclear transport. The N-termini nuclear localization signal mediates t...
We have identified a novel Sox gene in zebrafish (Danio rerio), Sox31, closely related to mammalian group B Sox genes. The gene is maternally expressed. Zygotic transcription starts at gastrulation, in the presumptive neuroectoderm. Later, expression is restricted to the developing central nervous system, including forebrain, midbrain, hindbrain and spinal cord.
Few pieces of legislation have affected so much so quickly and profoundly as the SarbaneseOxley (often abbreviated ‘‘SoX’’) Act of 2003. Triggered by accounting scandals such as Enron’s several years ago, SoX has many provisions, some of the most important of which require management of publicly traded companies to establish and maintain ‘‘an adequate internal control structure and procedures f...
Applying the tree bisection and reconnection (TBR) algorithm, we have developed a heuristic method (maximum likelihood (ML)-TBR) for inferring the ML tree based on tree topology search. For initial trees from which iterative processes start in ML-TBR, two cases were considered: one is 100 neighbor-joining (NJ) trees based on the bootstrap resampling and the other is 100 randomly generated trees...
