연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract AI-Helper 아이콘AI-Helper

MicroRNAs (miRNAs) function as a key regulator of diverse cellular functions. To find out novel miRNAs that promote the differentiation of mouse embryonic stem cells (mESCs), we compared the miRNAs expression profiles of mESCs under self-renewal vs. differentiation states. We noticed that miR-222 wa...

제안 방법

  • Graphical data are presented as means ± SD. Each experiment was performed at least three times and subjected to statistical analysis. Statistical significance between two groups was determined using Student’s t-test.
  • In this study, we analyzed the expression profiles of miRNAs during the differentiation of mouse embryonic stem cells (mESCs). We found that miR-222 was prominently upregulated during the differentiation of mESCs.
  • First-Strand Synthesis System (Invitrogen), according to the manufacturer’s instructions. Real-time PCR was carried out in triplicate with the Quantitect SYBR Green PCR kit (Qiagen, Valencia, CA, http://www.qiagen.com) and CFX96 Real-time System (Bio-Rad Laboratories, Richmond, CA http://www.bio-rad.com). For quantification, target genes were normalized with the glyceraldehyde 3-phosphate dehydrogenase (GAPDH) gene.
  • Despite several studies reported the function of miR-222 in cancer, the role of miR-222 in ESCs has not been reported. To confirm the result of miRNAs array, we quantitatively analyzed the expression level of miR-222 in 2 days old EBs and spontaneously differentiated EBs. As shown in Figure 2A, the miR-222 expression was not activated in EBs but it was significantly increased during the differentiation of EBs.
  • com). To induced differentiation, we formed Embryonic bodies (EBs) in LIF-deficient ESCs medium (as described above) by suspension culture and media changed every two days. To induce spontaneous differentiation, mESCs were cultured in LIF-deficient ESC medium with 500 nM all-trans retinoic acid (RA) (Lee et al.
  • To study the role of miR-222 for initiation of mESCs’ differentiation, we suppressed miR-222 using antagomiR-222 and then examined the differentiation pattern of mESCs.

대상 데이터

  • AntagomiR for miR-222 was purchased from Ambion (ABS-4427975, Gene ID: 000397) and transfection was performed according to the manufacturer’s instructions using Lipofectamin 2000 (Invitrogen).

데이터처리

  • Statistical significance between two groups was determined using Student’s t-test.
