Curr Microbiol

October 2024

Laboratory of Influenza Research, College of Veterinary Medicine, Chungnam National University, Daejeon, 34134, Republic of Korea.

ZIKV was a mosquito-borne neglected tropical pathogen until it spread into the Pacific and South America, followed by large human outbreaks related to congenital abnormalities in neonates and neurological disorders in adults. The following study used the C57BL/6 IFNAR1 receptor knockout (IFN AR1) mouse model to understand the role of selected cytokines and apoptotic factors in the pathogenicity of ZIKV strain PRVABC59. Mice infected with 10 particles of Zika viruses died until 9 days post infection.

Mitoquinone improves porcine embryo development through modulating oxidative stress and mitochondrial function.

Theriogenology

January 2025

Laboratory of Theriogenology, College of Veterinary Medicine, Chungnam National University, Daejeon, 34134, Republic of Korea. Electronic address:

Oxidative stress caused by excess reactive oxygen species (ROS) is one of the main causes of low efficiency in in vitro production of embryos. These ROS can cause mitochondrial dysfunction and apoptosis, resulting in poor embryo development. Therefore, to prevent mitochondrial damage and apoptosis caused by ROS, we investigated the effects of mitoquinone (MitoQ), a mitochondrial-targeted antioxidant, on the in vitro culture (IVC) of porcine embryos.
