  • Objective: Prostaglandins (PGs) function in various reproductive processes, including luteolysis, maternal pregnancy recognition, conceptus development, and parturition. Our earlier study has shown that PG transporters ATP-binding cassette, subfamily C, member 4 (ABCC4) and solute carrier organic anion transporter family, member 2A1 (SLCO2A1) are expressed in the uterine endometrium in pigs. Since several other PG transporters such as ABCC1, ABCC9, SLCO4C1, and SLCO5A1 are known to be present in the uterine endometrium, this study investigated the expression of these PG transporters in the porcine uterine endometrium and placenta. Methods: Uterine endometrial tissues were obtained from gilts on day (D) 12 and D15 of the estrous cycle and days 12, 15, 30, 60, 90, and 114 of pregnancy. Results: ABCC1, ABCC9, SLCO4C1, and SLCO5A1 mRNAs were expressed in the uterine endometrium, and levels of expression changed during the estrous cycle and pregnancy. Expression of ABCC1 and ABCC9 mRNAs was localized mainly to luminal and glandular epithelial cells in the uterine endometrium, and chorionic epithelial cells during pregnancy. Conceptuses during early pregnancy and chorioallantoic tissues from mid to late pregnancy also expressed these PG transporters. $Estradiol-17{\beta}$ increased the expression of ABCC1 and SLCO5A1, but not ABCC9 and SLCO4C1 mRNAs and increasing doses of $interleukin-1{\beta}$ induced the expression of ABCC9, SLCO4C1, and SLCO5A1 mRNAs in endometrial explant tissues. Conclusion: These data showed that several PG transporters such as ABCC1, ABCC9, SLCO4C1, and SLCO5A1 were expressed at the maternal-conceptus interface, suggesting that these PG transporters may play an important role in the establishment and maintenance of pregnancy by regulating PG transport in the uterine endometrium and placenta in pigs.

  • $Cant{\acute{u}}$ syndrome (CS, OMIM 239850) is a very rare autosomal dominantly inherited genetic disease characterized by congenital hypertrichosis, neonatal macrosomia, a distinct facial features such as macrocephaly, and cardiac defects. Since the first description by $Cant{\acute{u}}$ et al. in 1982, about 50 cases have been reported to date. Recently, two causative genes for CS has been found by using exome sequencing analyses: ABCC9 and KCNJ8. Most cases of clinically diagnosed CS have resulted from de novo mutations in ABCC9. In this study, we report three independent Korean children with CS resulting from de novo ABCC9 mutations. Our patients had common clinical findings such as congenital hypertrichosis, distinctive facial features. One of them showed severe pulmonary hypertension and hypertrophic cardiomyopathy, which require medical treatment. And, two patients had a history of patent ductus arteriosus. Although two of our patients had shown early motor developmental delay, it was gradually improved during follow-up periods. Although CS is quite rare, there are the concerns about development of various cardiac problems in the lifetime. Therefore, an accurate diagnosis followed by appropriate management and genetic counseling should be provided to CS patients.

  • To identify genes whose expression correlated with biological features of therapy-related AML (t-AML), we analyzed the expression profiles of de novo AML t(9;11) and t-AML t(9;11) bone marrow samples using previously published SAGE data. Three-hundred twenty-nine transcripts that satisfied statistical (P<0.05) and magnitude-of-change ($\geq$ 4-fold) criteria were identified as differentially expressed between de novo AML t(9;11) and t-AML t(9;11) cells. Of these transcripts, 301 (91%) matched known genes or ESTs and were classified according to functional categories (http://david.abcc.ncifcrf.gov/). The majority of differentially expressed genes in t-AML t(9;11) were involved in the regulation of biological and metabolic processes. Especially prominent among these were genes related to immune and drug responses. These results establish a framework for developing new drugs for the treatment of t-AML.

  • 비증후군성 구순구개열을 발생시키는 주요유전자로 추측이 되는 OFC1 유전자(위치 염색체 6p24.3)의 한국인에서 나타나는 특성을 연구하였다. 3대에 걸쳐서 처음으로 비증후군성 구순구개열이 나타난 40 명의 환자(남자 20명, 여자 20명, 평균 나이 : 14.2세)와 3대에 걸쳐서 비증후군성 구순구개열을 포함한 어떤 선천성 기형도 나타나지 않았던 정상 성인 40명 (남자 20명, 여자 20명, 평균 나이 : 25.6세)을 연구 대상으로 하였다. 중합효소 연쇄 반응법을 이용하여 OFC1 유전자를 분리 증폭한 후, 염기 서열 분석을 통해서 대립유전자형을 밝히고, BLAST 와 Pedant-Pro 데이터베이스를 이용하여 단백질의 상동성 검색을 수행하였으며, 그 결과는 다음과 같다. 1. OFC1 유전자는 'CA' 연쇄반복서열을 가진 극소위성 표지자로 밝혀졌다. 2. 환자군과 대조군의 OFC1 유전자의 특별한 차이는 발견되지 않았다. 3. 한국인에서 나타난 'CA' 연쇄반복서열의 형태는 'ABI linkage map 2'의 TA(CA)11TA(CA)10과는 달리, TA(CA)n의 형태를 띄었으며, 연쇄반복의 수는 17회에서 26회로 다양하게 나타났다. 4. 'CA' 연쇄반복서열의 횟수에 따라서, 9가지의 대립유전자형이 발견되었으며, 나타나는 빈도는 환자군과 대조군에서 유사하였다. 5. 'ABI linkage map 2'의 'CA' 연쇄반복서열 사이의 염기서열 T가 한국인에서는 C로 치환되어 있었지만, ORF예측을 하였을 때 예상되는 아미노산의 배열 차이는 관찰되지 않았다. 6. 한국인 OFC1 유전자의 염기서열로 예측되는 단백질을 알아보기 위하여 BLAST 검색을 한 결과, Telomerase reverse transcriptase(TERT, locus 5p15.33, NCBI Genome Annotation ; NT023089)와 Nucleotide binding protein 2(NBP2, locus 17q22, NCBI Genome Annotation; NT010783)가 유사한 구조를 가지는 단백질로 밝혀졌다. 7. Pedant-Pro 데이터베이스로 단백질 구조의 상동성 검색을 한 결과, OFC1 유전자는 적어도 하나의 transmembrane region과 non-gloular region을 가지는 구조로 밝혀졌다.
