  • 지방산 결합 단백질(FABP)은 LCFA 수송, 지질 합성, 저장을 용이하게 하고, 염증을 포함한 다양한 경로에 영향을 미치는 신호 분자로 작용한다. 특히 FABP4는 혈관 및 심장관련 질환과 관련이 있으며, 대식세포 매개 염증 반응에서 역할을 한다. 이전의 연구들은 FABP4를 지방 생성을 위한 대표적인 바이오 마커일 뿐만 아니라, 면역 반응과도 상관관계가 있는 것으로 확인하였다. 본 연구는 톨-유사 수용체 3(TLR3) 활성화에 의한 닭 FABP4(chFABP4) 유전자의조절을 조사하고 chFABP4 전사 조절에 관여하는 신호 경로를 결정하는 것을 목표로 한다. 우리는 TLR3 자극 DF-1 세포에서 chFABP4의 전사 조절을 분석하였다. 결과는 TLR3 리간드인 폴리이노신-폴리시티딜산(PIC)으로 자극 시 chFABP4가 상향 조절되었음을 보여주었다. 특히 chFABP4 전사는 NF-κB 신호 경로에서 독립적으로 조절되었다. p38 억제에서 상향 조절되어 p38 신호 경로가 TLR3 활성화 DF-1 세포 내에서 chFABP4 전사를 억제할 수 있음을 보여주었다. 이와는 대조적으로, JNK 신호 경로 억제에서는 chFABP4 발현이 하향 조절되었으며, 이는 대식세포의 연구 결과와 일치하며, TLR3 활성화에 반응하여 DF-1 세포에서 chFABP4 전사를 위한 JNK 신호 전달 경로의 긍정적인 조절을 시사한다. MEK 경로 억제는 NF-κB 신호 전달과 유사한 조절을 초래하였다. 이러한 결과는 각 MAPK가 TLR3 활성화에 반응하여 DF-1 세포에서 chFABP4의 전사 조절에 차별적으로 기여함을 시사한다.

  • There is limited information of the genetic effect for fatty acid composition in chicken meat. This study assessed the association of FABP3 and FABP4 genes affecting fatty acid composition in broilers. Two single nucleotide polymorphisms (SNPs) were detected in FABP3 gene and five SNPs were identified in FABP4 gene. The SNPs located in intron 1 and exon 1 of FABP3 and FABP4, respectively, were used for genotyping using PCR-RFLP method. The SNPg.285C >T in FABP4 showed suggestive association with high arachidonic acid (C20 : 4) in CT genotypes (P = 0.068). However, the SNP g.508C > T in FABP3 showed no significant associations with fatty acid composition. These results are the first report to investigate the SNPs in FABP3 and FABP4 genes and their associations with fatty acid composition, although we only found the possible association of FABP4 SNP with fatty acid composition. These results should provide valuable information for further investigation of the genes affecting fatty acid composition in chicken.

  • The aim of this study was to determine whether single nucleotide polymorphisms (SNP) in the beef cattle adipocyte fatty-acid binding protein 3 and 4 (FABP3 and FABP4) genes are associated with carcass weight (CW) and back fat thickness (BF) of beef cattle. By direct DNA sequencing in 24 unrelated Korean native cattle, we identified 20 SNPs in FABP3 and FABP4. Among them, 10 polymorphic sites were selected for genotyping in our beef cattle. We performed SNP, haplotype and linkage disequilibrium studies on 419 Korean native cattle with the 10 SNPs in the FABP genes. Statistical analysis revealed that 220A>G (I74V) and 348+303T>C polymorphisms in FABP4 showed putative associations with BF traits (P=0.02 and 0.01, respectively). Our findings suggest that the polymorphisms in FABP4 may play a role in determining one of the important genetic factors that influence BF in beef cattle.

  • FABPs, 15 kDa organic substances, are small intracellular proteins which have a primary role to regulate fatty acid uptake and intracellular transport. This study was conducted to identify SNPs in the two FABP family genes and their associations with the body weight traits in Korean native chicken (KNC). Two SNPs, namely g.508C>T of FABP3 gene and g.285C>T of FABP4 gene, have been genotyped by using PCR-RFLP method. The results showed that FABP3 was significantly associated with body weight at birth, body weights at 12 to 20 weeks, and also slaughter weight. Moreover, the g.285C>T SNP of FABP4 gene was not associated with any body weight traits. These results suggested that the g.508C>T SNP of FABP3 genes can be used as molecular markers to select KNC having desirable body weights.

  • The bovine fatty acid binding protein 4 and 5 (FABP4 and 5) is a major positional and physiological candidate gene for the bovine marbling and carcass weight. The aim of this study was to evaluate the association between economic traits of Korean cattle (Hanwoo) and genetic variation in fatty acid binding protein 4 and 5 (FABP4 and 5) genes within carcass/meat quality traits and the before/after of fatting in breed Hanwoo. Here, we characterized the nucleotide polymorphism of FABP4 and 5 in 86 cattle. We were detected the variability of three types (GG, AG, and AA) by PCR, and economic traits were analyzed by the mixed regression model implemented in the ASReml program. As the result of statistical and supersonic analysis, FABP4 gene was highly showed significant effect (p<0.006) on marbling score (MS), in contrast FABP5 gene was lowed (p<0.084) on MS before fatting. But, FABP4 gene was highly showed significant effect (p<0.0054) on MS, in contrast FABP5 gene lowest (p<0.0899) on MS in the after of fatting. Compare to supersonic result before fatting in FABP4 gene, it was detected type GG: (p<7.18), AG: (p<8.50), and AA: (p<10.50) (n=50), showed type GG: (p<4.88), AG: (p<2.33), and AA: (p<0.00) after weed out (n=20). Futhermore, it was detected type GG: (p<9.30), AG: (p<7.95), and AA: (p<7.40) (n=50) before fatting in the FABP5 gene. It was shown type GG: (p<2.67), AG: (p<3.50), and AA: (p<5.00) after weed out (n=50). Our results indicate that FABP4 and 5 gene transcription is regulated by the environment of feeding and management, and suggest that feeding and management could be potential key in determining FABP4 and 5 genes transcription for carcass/meat quality traits in breed Hanwoo.

  • This study was conducted to analyze the genotypes and genes of FABP3 (Fatty-acid Binding Protein 3) in pigs using MSPI restriction enzyme and electrophoresis. Analysis of data collected from a total of 210 crossbred pigs (LYD or YLD) in Chungcheongnam-do, Korea, revealed the following. The AA genotypes of FABP3 were detected in the 750 bp and 100 bp bands, while the Aa heterotype appeared in the 850, 750 and 100 bp bands and the aa recessive homotype was detected in a single band of 850 bp. The genotype frequency of AA, Aa and aa was 46.67%, 51.43% and 1.90%, respectively. The genetic equilibrium of this population showed a significant difference (p<0.001) based on a ${\chi}^2$-test. The carcass weight, backfat thickness, marbling score, pH, drip loss, cooking loss, and meat color based on the CIE $L^*$, and $b^*$ values according to genotypes of FABP3 did not differ significantly (p>0.05); however, the CIE $a^*$ values did (p<0.05).

  • 본 연구는 재래돼지와 랜드레이스를 기초축으로 이용한 F$_2$ 241두에 대해 Heart Fatty Acid- Binding Protein 유전자와 연관되어 있는 PCR- RFLP를 이용하여 그 다형성을 조사하고 돼지의 성장형질, 도체형질, 육질형질과 그 유전자형간의 연관성을 구명코자 실시하였다. H-FABP PCR-RFLP는 두 쌍의 primer에 의한 850bp와 700bp의 증폭산물을 HaeⅢ와 HinfⅠ제한효소를 사용하여 실시되었다. HaeⅢ을 이용한 PCR-RFLP 유전자형은 DD형/700+150bp, Dd형/700+400+300+ 150bp 그리고 dd형/400+300+150bp의 DNA 단편을 보였으며, Hinf1에 의한 유전자형은 HH형은 350+180+130bp, Hh형은 350+220+180+130bp, hh형/350+220+130bp의 절단된 DNA 단편을 보였다. H-FABP/HaeⅢ 유전자형 중에서 12주령 체중은 DD형에 비해 Dd와 dd형에서 유의적으로 높은 값을 보였으며(p〈0.001), 3주령 체중 (p〈0.01)과 5주령, 30주령 체중 (p〈0.05)에 경우도 Dd와 dd형에서 유의적으로 높게 관찰되었고(Table 3), 특히 ‘d’ 대립유전자가 체중과 연관성이 있음이 관찰되었다. H-FABP/HinfⅠ의 유전자형과 표현형질의 연관성을 보면 12주령, 30주령 체중 및 도체지방 과 등지방 두께에서는 hh형에 비해 HH와 Hh형에서 유의적으로 높게 나타났으며(p〈0.001), 5주령 체중과 근내지방 함량에서도 HH형에서 유의적으로 높게 관찰되었고(p〈0.05), 특히 ‘H’ 대립유전자가 체중과 도체지방, 등지방 두께 및 근내지방 함량과 연관성이 있음이 관찰되었다. 따라서 돼지성장 및 지방축적과 관련한 선발력을 높이기 위해 H- FABP PCR-RFLP(HaeⅢ & HinfⅠ)를 분자생물학적 marker로 사용할 수 있을 것으로 사료된다.

  • Although schistosomicidal drugs and other control measures exist, the advent of an efficacious vaccine remains the most potentially powerful means for controlling this disease. In this study, native fatty acid binding protein (FABP) from $Fasciola$ $gigantica$ was purified from the adult worm's crude extract by saturation with ammonium sulphate followed by separation on DEAE-Sephadex A-50 anion exchange chromatography and gel filtration using Sephacryl HR-100, respectively. CD1 mice were immunized with the purified, native $F.$ $gigantica$ FABP in Freund's adjuvant and challenged subcutaneously with 120 $Schistosoma$ $mansoni$ cercariae. Immunization of CD1 mice with $F.$ $gigantica$ FABP has induced heterologous protection against $S.$ $mansoni$, evidenced by the significant reduction in mean worm burden (72.3%), liver and intestinal egg counts (81.3% and 80.8%, respectively), and hepatic granuloma counts (42%). Also, it elicited mixed $IgG_1/IgG_{2b}$ immune responses with predominant $IgG_1$ isotype, suggesting that native $F.$ $gigantica$ FABP is mediated by a mixed Th1/Th2 response. However, it failed to induce any significant differences in the oogram pattern or in the mean granuloma diameter. This indicated that native $F.$ $gigantica$ FABP could be a promising vaccine candidate against $S.$ $mansoni$ infection.

  • 본 연구는 비육돈에서 지방세포지방산결합단백질(A-FABP) 유전자의 유전자형과 도체형질의 상관관계를 조사하였다. 유전자 A-FABP의 프로모터 영역에 대해 HinfI-RFLP를 이용하여 유전자형을 조사한 결과 두 가지 유전자형(-406T/T T/C)들이 발견되었고 C/C는 발견되지 않았다. 유전자형 중 -406C/C 동형접합자가 발견되지 않는 이유는 비육돈 생산에 관여하는 돼지 품종들 중에서 Duroc 품종만이 이 유전자에 대한 고도의 다형성을 나타내기 때문으로 추정되었다. 유전자형 -406C/-를 나타내는 돼지들은 근내지방과 도체중이 통계적으로 유의적인 증가함을 나타내었으나 (p<0.05), 그 외의 도체형질들(조지방, 육색, 조직감, 수분 삼출도, 근육분리도)은 유의한 차이를 나타내지 않았다 (p>0.05). 본 연구를 통해 돼지 A-FABP 유전자의 -406C/- 유전자형이 근내지방에 대한 유용한 분자 마커가 될 수 있을 뿐만 아니라 다형성이 비육돈의 근내지방에 대한 유용한 분자 마커가 될 수 있으며, 특히 Duroc 품종을 최종 종모돈으로 이용할 경우 이 유전자형을 보유한 돼지를 이용하는 분자육종체계에서 marbling이 잘 된 돼지의 생산을 통한 육질 개선에 기여할 것으로 사료된다.
