Accurate information on the genetic and phenotypic characteristics and diversity of the indigenous Farm Animal Genetic Resources (FAnGR) is the basis on which their present and future sustainable utilization and conservation should be made. The paper describes the objectives, structure, functionality, content, utility and future prospects of the Country- Domestic Animal Genetic Resources Information System (DAGRIS) of ILRI. This electronic database is designed to cater for the needs of researchers, policy makers, development practitioners, eachers, students and farmers in developing countries for efficient access to available published and grey literature from past and present research results on the origin, distribution, diversity, present use and status of selected Farm Animal Genetic Resources (FAnGR) of the countries. Development of the country-modules of c-DAGRIS in English and French for Anglophone and Francophone countries is finalized and ready to be used.

The number of abandoned dogs is increasing with the worsening of the economy and the rising of feed value. It was becoming a serious social problem because of the disease transmission and destruction of natural ecosystems by abandoned dogs been wild animal. In order to solve these problems, companion dogs necessary to secure its own genetic information and to establish the systematic tracking system. Using multiplex-PCR method with 27 microsatellite marker (MS marker) divided 3 set, various alleles occurring to 6 dog breed (Labrador Retriever, German Shepherd, English Springer Spaniel, Belgian Malinois, Jindo Dog, PoongSan Dog) make use of markers to determine allele frequency and heterozygosity. MS marker FH2834 and FH2790 have only two allele and most were found in 13 alleles at FH3381 and FH3399. Average heterozygosity of MS marker is 0.534 and especially, heterozygosity represented the highest value of 0.765 at FH3381. So, it was recognized appropriate allele frequency for individual identification and paternity diagnosis in companion dogs. Using multiplex-PCR method with MS marker, various alleles occurring to dog breed make use of markers to deter mine individual identification and paternity diagnosis, traits associated biomarkers and breed-specific marker for faster, more accurate and ways to reduce the analysis cost. Based on this result, a scientific basis was established to the existing pedigree data by applying genetics additionally. Animal registration system is expected to be conducted nationwide in future. The method expects to very useful this system.

Economic traits are quantitative traits and are mostly controlled by a large number of genes. Some these genes tend to have a large effect on quantitative traits in cattle and are known as major genes primarily located at quantitative traits loci (QTL). However, in practice, QTL is linked to allele associates of the gene controlling traits of interest. It is hypothesized that if QTL explaining a part of genetic differences between animals are detected, the effect of the genes located at QTL could assist in estimating an animal’s true genetic value. Therefore, QTL information could probably provides accuracy of breeding value estimation as well as more genetic gain through selection of animals at relatively younger age. Marker assisted selection (MAS) is the indirect selection process where a quantitative trait of economic importance is selected not just based on the trait itself but also on the basis of marker linked to QTL. MAS could be useful for traits that are difficult to measure, exhibit low heritability, and are expressed late in development. Major genes which are responsible for QTL could possibly be identified first by using different techniques such as gene expression analysis and QTL mapping. Thereafter, the information generated could be implemented for MAS in estimating breeding value. In this review we focused on delivering genome information into Hanwoo breeding program.

Mesenchymal stem cells (MSCs) are considered to be attractive approaching in gene or drug delivery for cancer therapeutic strategies. In this study, the ability and feasibility of human bone marrow derived MSCs expressing the cytosine deaminase (CD)/5-Fluorocytosin (5-FC) prodrug was evaluated to target human osteosarcoma cell line Cal-72. At first, the fibroblast-like cells were successfully obtained from human bone marrow and demonstrated that they contained full of stem characteristics by the ability of differentiation into adipocyte/osteocyte and expression of typical mesenchymal markers CD90, CD44, while negative for CD34 and CD133 markers. We established the stable CD-expressing MSCs cell line (CD-MSCs) by transfection of pEGFP-C3 containing cytosine deaminase::uracil phos-phoribosyltransferase (CD::UPRT) gene into MSCs, and confirmed that the manipulated MSCs still remained full characteristics of multipotent cells and shown migration toward human osteosarcoma cancer cells Cal-72 as high as origin MSCs. Based on bystander effect, the therapeutic CD-MSCs significantly augmented the cytotoxicity on cancer cell Cal72 in either direct co-culture or conditioned medium in the presence of 5-FC. Moreover, in osteosarcoma cancer- bearing mice, the therapeutic CD/5-FC MSCs showed the inhibition of tumor growth compared with control mice which was s.c injected with only Cal72. Our findings suggest that these therapeutic CD-MSCs may be suitable and viable cellular vehicles for targeting human osteosarcoma cancer.
