introduction genetic background has known to be associated with the outcome of human t cell lymphotropic virus (htlv) type i infection. in the present study we investigate the association between gm-csf gene polymorphisms with the outcome of htlv-i infection. materials and methods we analyzed 3 single-nucleotide polymorphisms in the promter region of granulocyte macrophage colony stimulating fa...

results pcslab is a weak promoter responding to come and its binding appears to be negative cooperative. although pcslab is partially controlled by comcde, it can respond to comcde regulation. supported by the obtained molecular evidence, cslab acts as a stabilizer of comcde signal on the patterns of its expression. conclusions pcslab is partially controlled by comcde. cslab is a stabilizer of ...

Transcriptional regulation of gene expression is controlled through the binding of sequence-specific DNA-binding proteins (transcription factors) to the regulatory regions of genes. The exact gene expression program of a cell is determined by the spectrum of transcription factors present with the nucleus of a cell. The presence of these factors is dependent upon the cell type being examined and...

The electrophoretic mobility shift assay (EMSA), or gel mobility shift assay, is a popular and powerful technique for the detection of RNA-protein interactions. It relies on the fact that naked RNA has certain mobility on nondenaturing gels, but if the RNA is bound by protein, the mobility of the RNA is reduced. Therefore, the binding of protein results in a characteristic upward shift of the R...

Electromobility shift assay is a simple, efficient, and rapid method for the study of specific DNA-protein interactions. It relies on the reduction in the electrophoretic mobility conferred to a DNA fragment by an interacting protein. The technique is suitable to qualitative, quantitative, and kinetic analyses. It can also be used to analyze conformational changes.

NtrC protein of piezophilic Shewanella violacea was overexpressed and purified, to confirm the protein-DNA interaction. An electrophoretic mobility shift assay demonstrated that the NtrC recognizes the sequence for NtrC binding within the region upstream of the glnA operon. Western blot analysis also showed that the NtrC is expressed at a higher level under high-pressure conditions than under a...

OBJECTIVES A request to report laboratory values to a specific number of decimal places represents a delicate balance between clinical interpretation of a true analytical change versus laboratory understanding of analytical imprecision and significant figures. Prostate specific antigen (PSA) was used as an example to determine if an immunoassay routinely reported to the hundredths decimal place...

Obesity is a health condition that, through a complex interaction of biopsychosocial and environmental factors, is associated with mobility disability. The mobility disability experienced by persons with obesity is associated with reduced health related quality of life (HRQoL) compared to persons without obesity. This paper will review and discuss functional mobility and its relationship to HRQ...
