One of the domesticated species; the dog has been selectively bred for various aims by human. The dog has many breeds, which are artificially selected for specific behaviors and morphologies. Dogs contribute their life to human as working dogs for guide, rescue, detection or etc. Working dogs requires good personality, such as gentleness, robustness and patience for performing their special duty. Many studies have concentrated on finding genetic marker for selecting the high-quality working dog. In this study, we confirmed quantitative expression patterns of eight genes (ABAT; 4-Aminobutyrate Aminotransferase, PLCB1; Phospholipase C, Beta 1, SLC10A4; Solute Carrier Family 10, Member 4, WNT1; Wingless-Type MMTV Integration Site Family, Member 1, BARX2; BarH-Like Homeobox 2, NEUROD6; Neuronal Differentiation 6, SEPT9; Septin 9 and TBR1; T-Box, Brain, 1) among brains tissues from four dog breeds (Beagle, Sapsaree, Shepherd and Jindo), because these genes were expressed and have functions in brain mostly. Specially, BARX2, SEPT9, SLC10A4, TBR1 and WNT1 genes were highly expressed in Beagle and Jindo, and Sapsaree and German Shepherd were vice versa. The biological significance of total genes was estimated by database for annotation, visualization and integrated discovery (DAVID) to determine a different gene ontology (GO) class. In these analyses, we suppose to these eight genes could provide influential information for brain development, and intelligence of organisms. Taken together, these results could provide clues to discover biomarker related to functional traits in brain, and beneficial for selecting superior working dogs.

the nervous system [17, 42, 46]. Thus, the aim of this study was to predict the relationships among personality traits (calmness, trainability, dog sociability, boldness, and etc.) of dogs. Gene expression profiles may reflect the complete per- sonality of regulatory pathways; therefore we describe the gene expression patterns of eight genes (ABAT, BARX2, NEUROD6, SEPT9, SLC10A4, PLCB1, TBR1, WNT1) in dog breeds.

제안 방법
A GO analysis was performed in order to confirm the biological function of the eight genes. The gene set was con- firmed as cellular GO terms, such as cell differentiation, mul- ticellular organismal process, and cellular developmental process.
In this point, it is important to select the suitable traits of special dog from many dog breeds. In this study, we pre- sented each gene expression patterns in four dog breeds, which provides the clue to study of each dog breeds of spe- cific traits.
Quantitative real-time RT-PCR was performed with the Rotor-Gene Q system (QIAGEN, Hilden, Germany) with a gene-specific primer set (Table 1). Each of amplification re- action mixture (20 μl) contained 7 μl of H2O, 10 μl of QuantiTech SYBR Green PCR Master Mix (QIAGEN, Hilden, NW, Germany), 1 μl each of forward and reverse primers at 10 nmol/ μl, and 1 μl of cDNA template.
We then per- formed gene ontology (GO) term analyses and each genes were grouped as GO terms. The results of significant GO terms were queried to the REViGO program in order to con- struct a scatterplot and interactive graph [44], and then we summarized GO terms on the 2D semantic space by seman- tic similarities. P-values were originated from the Benjamini and Hochberg false discovery rate (FDR), and the color of circles indicates enriched GO terms with FDR <0.

Each GO terms of eight genes were queried to the REViGO program. (A) Scatter plots of GO terms from eight genes are viewered, and circles indicated by color depict significantly enriched GO terms with FDR <0.05. (B) Integrated graph of biological process from eight genes is presented by integrating nodes.
In conclusion, we selected eight genes related to brain functions, then confirmed their expression patterns, func-tions, and network. Total genes have a similar expression patterns, and their function is related to cell differentiation, cellular developmental process and multicellular organismal process.
