KIR2DL4 is an important immune modulator expressed in natural killer cells; HLA-G its main ligand. We have characterized the genetic diversity by considering promoter, all exons, and introns a highly admixed Brazilian population sample using massively parallel sequencing. introduce molecular method to amplify sequence complete gene. To avoid mapping bias genotype errors commonly observed gene f...

Strains of Saccharomyces cerevisiae carrying a 1.4 x 10(6) dalton double-stranded (ds) RNA in virus-like particles (the killer plasmid or virus) secrete a toxin that is lethal to strains not carrying this plasmid (virus). The mak10 gene is one of 24 chromosomal genes (called pets, mak1, mak2,...) that are needed to maintain and replicate the killer plasmid. We report here isolation of spontaneo...

A number of genetic mechanisms have been suggested for driving anti-pathogen genes into natural populations. Each of these mechanisms requires complex genetic engineering, and most are theoretically expected to permanently spread throughout the target species' geographical range. In the near term, risk issues and technical limits of molecular methods could delay the development and use of these...

Natural killer cells belong to the family of innate lymphoid cells comprising the frontline defense against infected and transformed cells. Development and activation of natural killer cells is highly dependent on interleukin-15 signaling. However, very little is known about the transcription program driving this process. The transcription factor Runx3 is highly expressed in natural killer cell...

Oxidative stress after major surgeries is associated with the development of poor clinical outcomes including delayed wound healing and increase in Pediatric Intensive Care Unit (PICU) length of stay. Due to the growth and development phase in childhood, the change in the levels of oxidative stress and inflammation is of high importance in these patients. Notably, the acute metabolic stress whi...

objective: the objective of this study is to develop and assess targeted pamam-peg nanocarrier with anti-tag72 nanobody for t-bid gene coding construct delivery into the human colonic adenocarcinoma cells. materials and methods: nanobody (nb) coding sequence was subcloned into psj expression vector for large-scale production and then nb was purified by ni++ affinity chromatography. sds-page an...

The spe2 gene of Saccharomyces cerevisiae codes for S-adenosylmethionine decarboxylase, an enzyme in the biosynthetic pathway for the polyamines spermidine and spermine. We previously found that spe2 mutants completely lacking enzymic activity have no spermidine or spermine when grown in polyamine-free medium and require spermidine or spermine for meiotic sporulation and optimal growth. We now ...

background: the sry gene (sry) provides instructions for making a transcription factor called the sex-determining region y protein. the sex-determining region y protein causes a fetus to develop as a male. in this study, sry of 15 spices included of human, chimpanzee, dog, pig, rat, cattle, buffalo, goat, sheep, horse, zebra, frog, urial, dolphin and killer whale were used for determine of bioi...
