Investigating the immunomodulatory effects of honeybee venom peptide apamin in platforms.

Apamin, an 18-amino-acid honeybee venom peptide, although traditionally recognized for its neurotoxic effects, demonstrates potent antimicrobial properties in our research when genetically expressed in . This antimicrobial efficacy is independent of its disulfide bonds and is enhanced when the peptide is membrane-tethered. Apamin selectively inhibits pathogenic bacteria, such as , , and , while promoting beneficial bacteria like thereby improving the gut microbiome.

Cloning and Spatiotemporal Expression Analysis of Gene cDNA in (Arctic Fox).

This study aimed to clarify the sequence characteristics and spatiotemporal expression patterns of the insulin-like growth factor 1 receptor () gene in (Arctic fox), thereby addressing the existing knowledge gap regarding -mediated growth regulation in this species. The findings establish a crucial foundation for subsequent investigations into the correlation between this gene and Arctic fox growth traits. Specific primers were designed based on the cDNA sequence of the canine gene (Accession No.

Testicular Transcriptome of Males and Pseudo-Males Provides Important New Insight into Sex Reversal of .

() is an ecological species found in China, Japan, Korea, and Russia. Like most amphibians, lacks heterotypic sex chromosomes, limiting the in-depth study of sex determination and sex reversal mechanisms. Previous studies have shown that certain environmental factors can modify genotypic females into phenotypic males, but the mechanism is still unknown.

Male heterogametic sex determination in Rana dybowskii based on sex-linked molecular markers.

Identifying the mechanism for sex determination in amphibians is challenging. Very little is known about sex determination mechanisms of Rana dybowskii, a species of importance to evolutionary and conservation biology. We screened for sex-linked molecular markers in R.

NF-κB pathway took part in the development of apoptosis mediated by miR-15a and oxidative stress via mitochondrial pathway in ammonia-treated chicken splenic lymphocytes.

Ammonia, a kind of gas with pungent smell, is harmful to livestock and people, and has bad influence on the atmosphere. However, the mechanism of splenic toxicity caused by ammonia is still poorly understood. The aim of present study was to investigate the effect of ammonia on chicken splenic lymphocytes from the perspective of apoptosis.

The complete mitochondrial genome sequence of Lindian Chicken () in China.

In this study, the first complete mitochondrial genome of Lindian Chicken () was sequenced in order to develop the mitogenome data for genus gallus. The complete mitogenome sequence is 16,785 bp in length, containing 37 genes (13 protein-coding genes, 2 ribosomal RNA, 22 transfer RNA genes, and one control region). The new sequenced complete mitogenome of Lindian Chicken will provide useful information for application in conservation genetics and evolution for this Near Threatened Chicken genomes.

The type and extent of injuries in vitrified mouse oocytes.

To improve the vitrification of mouse oocytes using straws, we attempted to estimate the type and extent of injuries during vitrification with a vitrification solution EAFS10/10. Injuries in oocytes were assessed based on cellular viability, the integrity of the plasma membrane, the status of the meiotic spindle/chromosomes, and morphological appearance. For morphologically normal oocytes, the ability to be fertilized and to develop into blastocysts was examined.

[Correlation analysis between MC3R and MC4R gene polymorphism and growth traits in pigeon.].

The SNPs in partial coding sequence of MC3R and MC4R genes were identified by polymerase chain reaction followed by single strand conformation polymorphism (PCR-SSCP) analysis and DNA sequencing in shack-Kee and Columba domestica from Harbin area. Correlation analysis between MC3R and MC4R polymorphism and growth and body composition traits was carried by the least square analysis. The genotypes of T91G mutation in MC3R gene and A903G mutation in MC4R gene proved to have significant association with body weight, carcass weight, and holo-carcass weight in shack-Kee (P<0.
