Sox family transcription factors play essential roles in cell differentiation, development, and sex determination. Sox2 was previously thought to be the sole Sox protein expressed in mouse embryonic stem (ES) cells. Sox2 associates with Oct3/4 to maintain self-renewal of ES cells. In the current study, digital differential display identified transcripts for an additional Sox family member, Sox1...

Pluripotent embryonic stem (ES) cells can generate all cell types, but how cell lineages are initially specified and maintained during development remains largely unknown. Different classes of Sox transcription factors are expressed during neurogenesis and have been assigned important roles from early lineage specification to neuronal differentiation. Here we characterize the genome-wide bindin...

Chronic high surface ozone (O3) levels and the increasing sulfur oxides (SOx = SO2+SO4) ambient concentrations over South Coast (SC) and other areas of California (CA) are affected by both local emissions and long-range transport. In this paper, multi-scale tracer, full-chemistry and adjoint simulations using the STEM atmospheric chemistry model are conducted to assess the contribution of local...

SOX proteins form a large family of transcription factors related by a DNA-binding domain known as the HMG box. Some 30 Sox genes have been identified in mammals and orthologues have been found in a wide range of other metazoans. Sox genes are highly conserved and are known to play important roles in embryonic development, including roles in gonadal, central nervous system, neural crest and ske...

AIM The aim of this study was to evaluate the impact of chemotherapy with molecular-targeting agents on liver metastases from colorectal cancer. PATIENTS AND METHODS Six patients with synchronous colorectal liver metastases who underwent hepatectomy after chemotherapy with S-1 and oxaliplatin (SOX) between January 2010 and December 2011 at the Department of Surgery, Kashiwa Hospital, the Jike...

Introduction: Anabolic activity is a crucial activity in articular chondrocytes and its failure is one major reason of osteoarthritic cartilage degeneration. Unclear are the intracellular factors responsible for upand down regulation of the molecules of interest. In this respect, the transcription factor Sox-9, a member of the HMG-domain transcription factor family, elicited much of interest as...

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...
