  • Publication number: 20220409698
    Abstract: The present invention relates to a composition which is for preventing or treating bone diseases and includes CCR2 as an active ingredient. It was confirmed that a C—C chemokine receptor type 2 (CCR2) protein, a polynucleotide encoding the CCR2 protein, or a mesenchymal stem cell transduced with the CCR2 according to the present invention neutralize bone disease factor MCP-1, thereby reducing the collagen epitope (CTX-II) and collagen metabolism factors (MMP1 and MMP3) relating to collagen absorption in the body. In addition, it was confirmed that the expression of the SOX9 gene and anti-inflammatory cytokines (TGF-? and IL-10) related to cartilage differentiation was significantly increased. Thus, the present invention has excellent regenerative ability against osteoarthritis and excellent pain suppression and alleviation effects, and thus can be effectively used for preventing or treating bone diseases such as osteoarthritis.

  • Publication number: 20200370101
    Abstract: The present invention is about SNPs which can be used to predict a risk of AD. The polymorphism, rs405509 is located at the position of 44905579 of 19th chromosome based on GRCh38.p7 version. According to the present invention, the rs405509 T allele increases the risk of AD in addition to APOE E4/E4. Furthermore, according to the analysis results for the cortical and hippocampal thickness between APOE genetic types, more severe atrophy was observed for the E4/4 subjects comparing to E3/E3 subjects in East Asian. In addition, still more severe cortical thickness atrophy was confirmed for the rs405509 T/T subjects in Caucasians having E4/E4 genotypes. Therefore, the present invention can be used to diagnose or predict a risk of AD and/or AD associated dementia, by determining genetic variations of both APOE E4/E4 and rs405509 T/T.
