In this paper, we investigate whether firm performance is affected by corporate governance and the change of corporate governance after Sarbanes-Oxley Act (SOX hereafter). We find that firm performance, on average, is negatively associated with the corporate governance after the passage of SOX. However, the firm performance is not significantly associated with the change of corporate governance...

The differentiated phenotype of chondrocyte is lost in pathological situations and after interleukin (IL)-1beta challenge. Wnt proteins and the inorganic pyrophosphate (PP(i)) transporter Ank regulate the differentiation process in many cell types. We investigated the possible contribution of Ank and/or PP(i) to the maintenance of the differentiated chondrocyte phenotype with special care to Wn...

The Kaposi's sarcoma-associated herpesvirus (KSHV) SOX protein, encoded by ORF37, promotes shutoff of host cell gene expression during lytic viral replication by dramatically impairing mRNA accumulation. SOX is the KSHV homolog of the alkaline exonuclease of other herpesviruses, which has been shown to function as a DNase involved in processing and packaging the viral genome. Although the exonu...

We document that firms’ management of accounting earnings increased steadily from 1987 until the passage of the Sarbanes Oxley Act (SOX), with a significant increase during the period prior to SOX, followed by a significant decline after passage of SOX. However, the increase in earnings management preceding SOX was primarily in poorly performing industries. We also show that the informativeness...

The importance of interactions between Sox and POU transcription factors in the regulation of gene expression is becoming increasingly apparent. Recently, many examples of the involvement of Sox-POU partnerships in transcription have been discovered, including a partnership between Sox-2 and Oct-3. Little is known about the mechanisms by which these factors modulate transcription. To better und...

Steroidogenic factor 1 (SF-1) is an essential factor in endocrine proliferation and gene expression. Despite the fact that SF-1 expression is restricted to specialized cells within the endocrine system, the only identified regulatory factors of SF-1 are the ubiquitously expressed E-box proteins (upstream stimulatory factors 1 and 2). Sequence examination of the SF-1 proximal promoter revealed a...

Sulfur oxides (SOx), particularly SO2 emitted by coal-fired power plants, produce long-term risks for cardiovascular disease (CVD). We estimated the relative risks of CVD and ischemic heart disease (IHD) attributable to SOx emission globally. National SOx reduction achieved by emissions control systems was defined as the average SOx reduction percentage weighted by generating capacities of indi...

OBJECTIVES SOX-10 has been shown to be a sensitive marker of cutaneous melanoma. This study aimed to evaluate Sox-10 expression in uveal melanoma. METHODS A total of 40 tissue blocks of enucleated eyes with uveal melanoma were cut and stained using an anti-SOX-10 mouse monoclonal antibody and HMB-45 antibody. RESULTS SOX-10 showed exclusive nuclear positivity in 100% of the uveal melanoma c...

Members of the claudin family constitute tight junction strands and are major determinants in specificity and selectivity of paracellular barriers. Transcriptional control of claudin gene expression is essential to establish individual claudin expression patterns and barrier properties. Using full genome expression profiling, we now identify sex-determining region Y-box (SOX)-18, a member of th...
