We looked for changes in gene expression and novel genes that could be involved in the interaction between glucose repression and oxidative stress response in the fission yeast, Schizosaccharomyces pombe, using a constitutive invertase mutant, ird11, which is resistant to glucose. BLAST analysis was made of the S. pombe genome.. Read More»

This study aimed to investigate polymorphisms of the eighth exon in the GFI1B gene among three indigenous Chinese goat breeds (QianBei Ma goats, GuiZhou white goats, and GuiZhou black goats). Furthermore, association analysis was conducted between these polymorphisms and growth traits. Polymerase chain reaction-single strand conformation polymorphism (PCR.. Read More»

Marine turtles are increasingly being threatened worldwide by anthropogenic activities. Better understanding of their life cycle, behavior and population structure is imperative for the design of adequate conservation strategies. The mtDNA control region is a fast-evolving matrilineal marker that has been employed in the study.. Read More»

The genus Mesosetum is a primarily South American genus with 42 species. Mesosetum chaseae, regionally known as âÂ?Â?grama-do-cerradoâÂ?Â?, is abundant in the Pantanal Matogrossense (Brazil); it is a valuable resource for livestock and for environmental conservation. We collected specimens from the Nhecolandia sub-region of the Brazilian Pantanal, located .. Read More»

Since molecular phylogenies of stichotrich ciliates started to be published, some remarkable contradictions to morphology- based classifications have been reported, such as the Convergent Evolution of Urostylids and Uroleptids (CEUU) hyphothesis, the Halteria paradox, the polyphyly of Oxytricha and of Stichotrichia. We hypothe.. Read More»

Nucleotide excision repair (NER) acts on a broad spectrum of large lesions, while base excision repair removes individual modified bases. Although both processes have been well studied in human cells, novel genes involved in these DNA repair pathways have been described. Using a heterologous complementation approach, we identi..

Polyporus umbellatus (Pers.) Fries is an endangered medicinal fungus in China with in vivo anticancer activity, but its genetic information is lacking. Eight natural P. umbellatus strains collected from 7 provinces in China were subjected to sequence-related amplified polymorphism markers to estimate the level and pattern of genetic diversity. Forty-nine .. Read More»

The peroxisome proliferators-activated receptor-γ coactivator-1α (PGC-1α) is a candidate gene for meat quality traits because of its prominent role in muscle fiber type switching and determination. We investigated the effects of the PGC-1α gene on chicken skeletal muscle fiber type switching and on othe.. Read More»

Ascorbate peroxidase (APX) plays a central role in the ascorbate-glutathione cycle and is a key enzyme in cellular H2 O2 metabolism. It includes a family of isoenzymes with different characteristics, which are identified in many higher plants. In the present study, we isolated the APX gene from Jatropha curcas L, which is similar with other previously ch.. Read More»

We identified three novel mutations of the GTP cyclohydrolase 1 (GCH1) gene in patients with familial dopa-responsive dystonia (DRD), but were unable to identify meaningful sporadic mutations in patients with no obvious family DRD background. To investigate whether GCH1 regional deletions account for the etiology of DRD, we screened for heterozygous exoni.. Read More»
