Characterization of the mitochondrial Huso huso genome and new aspects of its organization in the presence of tandem repeats in 12S rRNA.

Background: The sturgeon group has been economically significant worldwide due to caviar production. Sturgeons consist of 27 species in the world. Mitogenome data could be used to infer genetic diversity and investigate the evolutionary history of sturgeons.

Evaluation of Alterations in DNA Methylation of Gene Upstream Regulatory Elements in Gastric Cancer and in Response to Diazinon Treatment.

Background: Little is known about cytochrome P450 3A4 (CYP3A4) DNA methylation and transcription alterations in gastric cancer.

Objective: In this paper, we initially aimed to address the effect of diazinon pesticide on DNA methylation and transcription changes of the CYP3A4 gene in a human gastric cell line. In the next step, we studied the methylation differences of CpG sites within the upstream regulatory regions of the CYP3A4 gene among human gastric cancerous and healthy tissues.

The effect of Spirulina platensis meal on antioxidant gene expression, total antioxidant capacity, and lipid peroxidation of rainbow trout (Oncorhynchus mykiss).

The study was conducted to investigate the effect of diets containing 0, 2.5, 5, 7.5, and 10% S.

Bovine Sex Determining Region Y: Cloning, Optimized Expression, and Purification.

Sex determining region Y gene (SRY) is located on Y chromosome and encodes a protein with 229 amino acids. In this study, ORF region of SRY with a length of 690 bp was synthesized using PCR and ligated to pET28a (+), then transformed in E.coli DH5α.

Oral administration of supplementary biotin differentially influences the fertility rate and oviductal expression of avidin and avidin-related protein-2 in low- and high-fertility broiler line hens.

Probable involvement of avidin and avidin-related protein-2 (AVR2) in sperm viability in the sperm storage tubules of turkeys has been suggested. The high affinity of biotin to avidin and its analogs is also well documented. The present study aimed to determine the effect of oral biotin on reproductive performance and oviductal mRNA expression of avidin and AVR2 in 2 broiler hen lines with different fertility rates.
