Transcriptome alterations in spermatogonial stem cells exposed to bisphenol A.

Anim Cells Syst (Seoul) 2022 10;26(2):70-83. Epub 2022 Apr 10.

Department of Animal Science & Technology, BET Research Institute, Chung-Ang University, Anseong-si, Republic of Korea.

Owing to their self-renewal and differentiation abilities, spermatogonial stem cells (SSCs) are essential for maintaining male fertility and species preservation through spermatogenesis. With an increase in exposure to plasticizers, the risk of endocrine-disrupting chemicals exerting mimetic effects on estrogen receptors, such as bisphenol A (BPA), has also increased. This has led to concerns regarding the preservation of male fertility. Read More

Detecting the differential genomic variants using cross-population phenotype-associated variant (XP-PAV) of the Landrace and Yorkshire pigs in Korea.

Anim Cells Syst (Seoul) 2021 29;25(6):416-423. Epub 2021 Nov 29.

Department of Agricultural Convergence Technology, Jeonbuk National University, Jeonju, Republic of Korea.

Although there have been many genome-wide association studies (GWAS) and selective sweep analyses to understand pig genomic regions related to growth performance, these methods considered only the gene effect and selection signal, respectively. In this study, we suggest the cross-population phenotype associated variant (XP-PAV) analysis as a novel method to determine the genomic variants with different effects between the two populations. XP-PAV analysis could reveal the differential genetic variants between the two populations by considering the gene effect and selection signal simultaneously. Read More
