Park YS, Oh MG, Kim SH. iSCNT embryo culture system for restoration of Cervus nippon hortulorum, presumed to be sika deer in the Korean Peninsula. PLoS One 2024; 19:e0300754.

Abstract
Sika deer inhabiting South Korea became extinct when the last individual was captured on Jeju Island in Korea in 1920 owing to the Japanese seawater relief business, but it is believed that the same subspecies (Cervus nippon hortulorum) inhabits North Korea and the Russian Primorskaya state. In our study, mt-DNA was used to analyze the genetic resources of sika deer in the vicinity of the Korean Peninsula to restore the extinct species of continental deer on the Korean Peninsula. In addition, iSCNT was performed using cells to analyze the potential for restoration of extinct species. The somatic cells of sika deer came from tissues of individuals presumed to be Korean Peninsula sika deer inhabiting the neighboring areas of the Primorskaya state and North Korea. After sequencing 5 deer samples through mt-DNA isolation and PCR, BLAST analysis showed high matching rates for Cervus nippon hortulorum. This shows that the sika deer found near the Russian Primorsky Territory, inhabiting the region adjacent to the Korean Peninsula, can be classified as a subspecies of Cervus nippon hortulorum. The method for producing cloned embryos for species restoration confirmed that iSCNT-embryos developed smoothly when using porcine oocytes. In addition, the stimulation of endometrial cells and progesterone in the IVC system expanded the blastocyst cavity and enabled stable development of energy metabolism and morphological changes in the blastocyst. Our results confirmed that the individual presumed to be a continental deer in the Korean Peninsula had the same genotype as Cervus nippon hortulorum, and securing the individual's cell-line could restore the species through replication and produce a stable iSCNT embryo.

Zhu W, Li J, Su J, Li J, Li J, Deng B, Shi Q, Zhou Y, Chen X. FOS-like antigen 1 is highly expressed in human psoriasis tissues and promotes the growth of HaCaT cells in vitro. Mol Med Rep 2014; 10:2489-94. [PMID: 25175497 DOI: 10.3892/mmr.2014.2509] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2013] [Accepted: 06/26/2014] [Indexed: 11/06/2022] Open
Abstract
Psoriasis is a multifactorial disease and the mechanisms involved in its pathogenesis remain to be elucidated. FOS‑like antigen 1 (Fra‑1) is a proto‑oncogene. It is a negative inhibitor of activator protein‑1 activity and possesses transforming activity. The effect of and possible mechanisms underlying Fra‑1 in psoriasis remain to be elucidated. In the present study, western blot analysis and reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) techniques were used to identify differentially expressed Fra‑1 in psoriatic and in normal control tissues. Compared with the control samples, the expression of normalized Fra‑1 genes in psoriasis was 12.6 times higher. Western blot analysis was used to assess the protein levels of Fra‑1. The results demonstrated that the protein expression of Fra-1 was high in tissues affected by psoriasis. This also corresponded with the results of RT‑qPCR. Fra‑1‑stable expressing HaCaT/Fra‑1 or control HaCaT/vector cell lines were then generated to elucidate the function of Fra‑1 in the growth of HaCaT cells. The results demonstrated that Fra‑1 promoted the growth of HaCaT cells in vitro by arresting the cell cycle and inhibiting cell apoptosis. These results suggested that Fra‑1 may be important in psoriasis.
