Article Abstract
The evaluation of the genetic structure of autochthonous pig breeds is very important for conservation of local pig breeds and preservation of diversity. In this study, 18 microsatellite loci were used to detect genetic relationship between autochthonous pig breeds [Black Slavonian (BS), Turopolje pig (TP), and Croatian wild boar] and to determine phylogenetic relationship among Croatian autochthonous pig breeds and certain Asian and European pigs using the mitochondrial DNA (mtDNA) D-loop sequence polymorphism. Relatively high degree of genetic variation was found between the observed populations. The analysis of mtDNA showed that haplotypes of the studied pig populations are different from the other European and Chinese haplotypes. BS pigs showed some similarities with Mangalitsa and Duroc breeds. The genetic distances of TP can be explained by high degree of inbreeding during the past century. Despite the European origin of Croatian pig breeds with some impact of Chinese breeds in the past, the results of present study show that genetic diversity is still pronounced within investigated breeds. Furthermore, the genetic diversity is even more pronounced between Croatian breeds and other European and Chinese pig breeds. Thus, conservation of Croatian pig breeds will contribute to overall genetic diversity preservation of pig breeds.

Ferroptosis is a form of iron-regulated cell death that plays a critical role in various aspects of female reproductive system development. These processes include the normal estrous cycle, ovarian formation, follicular maturation, ovulation, and pregnancy, all of which are essential for maintaining reproductive health in female animals. However, excessive iron leads to the accumulation of reactive oxygen species within cells, disrupting intracellular redox balance, inducing mitophagy, membrane rupture, and lipid peroxidation, which can damage tissues and cells, ultimately resulting in ferroptosis.

In light of the challenges posed by global climate change, the environmental adaptability of organisms is becoming increasingly important. The Wuzhishan (WZS) pig, tolerant to high heat and humidity, is an ideal model for genomic study. By characterizing its genome and assessing its genetic diversity and runs of homozygosity (ROH), we can gain insights into its current conservation status and genomic architecture.

Japanese encephalitis virus (JEV) is a significant flavivirus that poses a threat to public health, as it induces encephalitis in humans and reproductive disorders in sows. We have recently identified that zinc finger protein 33B (ZNF33B) is required for JEV infection by CRISPR-based functional genomic screening, yet the precise functions and mechanisms are not fully comprehended. In this study, ZNF33B was found to be involved in JEV infection, wherein it bound with JEV RNA to enhance its stability during replication.

Copper (Cu) supplementation is essential in pig nutrition; however, its effects on performance, trace element accumulation in edible tissues, and environmental excretion require careful evaluation. In the present study a total of 24 male, castrated fattening pigs of two different hybrid mast lines (11 weeks of age) were divided according to their initial body weight (25.8 ± 3.

Canine somatic cell nuclear transfer (SCNT) is a powerful technology that can be used to clone beloved companion dogs, produce valuable working dogs, rescue endangered canine breeds, and create genetically engineered dogs. Nevertheless, the application of this technology is hindered by the low developmental efficiency of canine SCNT embryos. It has been shown that in pig and horse cloning using mesenchymal stem cells (MSCs), compared with fibroblasts, as donor cells can enhance the developmental potential of SCNT embryos.
