  • 붉은 털 원숭이의 유전체는 인간의 것과 93% 정도로 동일하여, 진화적 연구 및 생물의학적 연구에 널리 활용되고 있다. 숙주 개체 내로 가동성 유전인자(TEs)의 삽입은 유전자 전사체의 다양성과 발현양상을 다르게 만든다. 본 연구에서는 붉은 털 원숭이의 뇌 조직으로부터 만든 cDNA 라이브러리에서 112개 전사체를 동정하여 분석하였다. 하나의 전사체 R54는 인간과 원숭이의 다양한 조직에서 유전자 발현양상을 비교분석 해 본 결과 서로 다른 패턴을 보여 주었다. 이러한 현상은 가동성 유전인자인 L2A의 삽입으로 인한 스플라이싱 도너 사이트가 변화된 것으로 생각된다. 따라서, 영장류의 진화과정에 있어 유전체 내로 TEs의 삽입은 전사체의 다양성과 유전자 발현 조절에 변화를 주는 것으로 시사된다.

  • Anatomical measurements were made at the necoropsy and sacrifice in a group of 41 adult female Rhesus monkey to determine the 34 characteristcs found in tracheas snd bronchus. Table 1, 2, 3, 4, and figure 1 were therefore prepared as a guide in the further use for illustrating monkey lung research. Summary of this report is as follows: 1. Accurate Knowledge of these measurements may have some value in pulmonary dissection and reconstructive procedures. 2. These studies may provide a more accurate determination of the monkey lungs. 3. The right and left bronchus length of the monkey is shorter than fornd in man. 4. The left bronchus length is more longer than the rrght bronchas. 5. There were large variation among the weight of adult female Rhesus monkey.

  • The objective of this study was to investigate the infection rate of gastro-intestinal tract parasites on acquired laboratory nonhuman primates, Vervet monkey, Cynomolgus monkey, and Rhesus monkey acquired from Japan and China. These monkeys have been acclimating at an individual housing condition after our legal quarantine period. We examined 133 fecal samples to investigate parasitic infection using direct smear and formalin-ether-sedimentation technique. As a result, total parasitic infection rate was 33.8% (n = 45/133) for all monkeys. Two species of macaques, cynomolgus and rhesus, were infected with Trichuris trichiura (4), Giardia lamblia (4) and Balantidium coli (41). Vervet monkeys, which had been controlled by individual housing system for a long time, were clear for parasitic infection. The protozoan, Balantidium coli was one of the most frequently detected in these monkey colonies. Double infection was noted in only 4 monkeys and involved with Trichuris trichiura and Balantidium coli. Serious clinical symptoms were not observed in the most of the infected monkeys, but the monkeys infected by Giardia lamblia showed intermittent or chronic watery diarrhea. Consequently, the prophylactic anthelmintic treatment and periodic monitoring are essential to preserve the SPF colonies in the laboratory facility.

  • YH 1885 (5,6-dimethyl -2-(4-fluorophenylamino)-4-(1-methyl -1,2,3,4-tetrahydroisoquinolin -2- yl) pyrimidine hydrochloride) was developed as an antiulcer drug. The objective of this study was to examine a comparative metabolism of YH1885 in rat, dog, monkey and human liver tissues and to determine the metabolite profiles produced by the four species. YH1885 was metabolized by liver 59 fractions from all four species. Control incubations containing 59 fraction but no cofactors, contained essentially no metabolites. Metabolism of YH1885 apparently became saturated in the concentration range studied because the % of YH 1885 metabolized decreased with increasing drug concentration for all four species. Six to nine metabolite peaks were detected in the incubations and the particular profile of metabolites varied with species. The total amount of metabolites formed by liver microsomes from human and monkey were less than microsomes from rat or dog. The major metabolite peak formed by rat liver 597actions fluted near the solvent front on the HPLC or remained at the origin in TLC, indicating that it contained one or more polar metabolites. Dog liver 59 fractions incubations contained four major metabolites that each accounted for about 15 to 20 % of the total radioactivity at the low concentration of YH1885. The metabolite profiles of YH1885 appeared to be similar in incubations with rhesus monkey and human liver 59 fraction. The amount of metabolites formed by rhesus monkey liver preparations was greater than that of human liver that contained prominent metabolite peaks with approximate relative retention time of 0.14 and 0.43.

  • Cathepsin F, which is encoded by CTSF, is a cysteine proteinase ubiquitously expressed in several tissues. In a previous study, novel transcripts of the CTSF gene were identified in the crab-eating monkey deriving from the integration of an Alu element-AluYRa1. The occurrence of AluYRa1-derived alternative transcripts and the mechanism of exonization events in the CTSF gene of human, rhesus monkey, and crabeating monkey were investigated using PCR and reverse transcription PCR on the genomic DNA and cDNA isolated from several tissues. Results demonstrated that AluYRa1 was only integrated into the genome of Macaca species and this lineage-specific integration led to exonization events by producing a conserved 3' splice site. Six transcript variants (V1-V6) were generated by alternative splicing (AS) events, including intron retention and alternative 5' splice sites in the 5' and 3' flanking regions of CTSF_AluYRa1. Among them, V3-V5 transcripts were ubiquitously expressed in all tissues of rhesus monkey and crab-eating monkey, whereas AluYRa1-exonized V1 was dominantly expressed in the testis of the crab-eating monkey, and V2 was only expressed in the testis of the two monkeys. These five transcript variants also had different amino acid sequences in the C-terminal region of CTSF, as compared to reference sequences. Thus, species-specific Alu-derived exonization by lineage-specific integration of Alu elements and AS events seems to have played an important role during primate evolution by producing transcript variants and gene diversification.

  • In order to understand the mechanism of the regulation of drug metabolizing enzyme gene expression, we have studied the induction of CYP1A1 and GST$\alpha$, $\mu$, $\pi$ enzymes in Japanese monkey and rhesus monkey after the treatment with 3-methylcholanthrene (3MC) and di-n- butyl phthalate (DBP) and bisphenol A (BPA). The levels of mRNA were measured by RT-PCR in brain, intestine and liver. In the case of adult monkey, treatment with 3MC induced CYP1A1 mRNA in liver by 10-fold. The treatment with DBP induced CYP1A1 mRNA. Effects of 3MC and DBP on GST mRNA expression was not clear. But GST$\mu$ was slightly inhibited by the treatment with 3MC and DBP. GST$\pi$ was not induced by the treatment with 3MC and DBP in liver. GST$\alpha$ was slightly induced by the treatment with 3MC and DBP in liver. In the case of fetus monkey, the basal levels of fetus CYP1A1 mRNA and GSTs mRNA were relatively low compared to adult monkey. As the age of monkey increased, the basal levels of CYP1A1 mRNA were also increased. 3MC induced the expression of CYP1A1 mRNA in liver. The levels of GST$\mu$ and GST$\alpha$ were not changed by the treatment with 3MC and DBP. GST$\pi$ was slightly induced by the treatment with 3MC and DBP.

The levels of mRNA were measured_by RT-PCR in brain, intestine and liver. In the case of adult monkey, treatment with 3MC induced CYP1A1 mRNA in brain by 2-fold. The treatment with DBP induced CYP1A1 mRNA. Effects of 3MC and DBP on GST mRNA expression was not clear. But GSTμ was slightly inhibited by the treatment with 3MC and DBP. GSTα was not induced by the treatment with 3MC and DBP in brain. GSTπ was slightly induced by the treatment with 3MC and DBP in brain. In the case of fetus monkey, the basal levels of fetus CYP1A1 mRNA and GSTs mRNA were relatively low compared to adult monkey. As the age of monkey increased, the basal levels of CYP1A1 mRNA were also increased. 3MC induced the expression of CYP1A1 mRNA in liver, whereas it didn't significantly induce CYP1A1 mRNA in brain. The levels of GSTμ and GSTα were not changed by the treatment with 3MC and DBP. GSTπ was slightly induced by the treatment with 3MC and DBP.
