Abstract:
본 발명은 SET/TAF-Iβ와 메틸화된 H3K27의 결합을 이용하는 유전자의 전사 조절 방법에 관한 것으로, 상기 SET/TAF-Iβ 와 메틸화된 H3K27의 결합은 H3S28의 인산화를 통해 저해되며, 이를 통해 유전자 전사의 활성화 또는 억제가 가능하다. 이러한 전사 조절 기작을 통해 SET/TAF-Iβ 타겟 유전자의 전사를 조절할 수 있어, 본 발명의 유전자 전사 조절 방법은 전사 조절 기작에 대한 연구 및 이를 이용한 인위적인 유전자 발현조절에 효과적으로 사용될 수 있다.
Abstract:
The present invention provides a pharmaceutical composition for preventing or treating myeloproliferative disorders, comprising one or more materials selected from the group consisting of histone H3K9 methyltransferase G9a protein, a segment thereof, an activator thereof, an expression regulator thereof and a histone H3K9 methyltransferase G9a-encoding gene, and a pharmaceutically acceptable carrier. The histone H3K9 methyltransferase G9a according to the present invention inhibits the transcription of JAK2, and promotes ATRA-induced cell differentiation of the promyelocytic leukemia cell line HL-60 in a differentiation inducing therapy using all-trans retinoic acid (ATRA, tretinoin) as a vitamin inducer, instead of a bone fracture treatment, and thus is useful in the form of a cell therapeutic agent or a protein therapeutic agent for the treatment or prevention of diseases associated with JAK2 activation and mutation, specifically, myeloproliferative disorders.
Abstract:
PURPOSE: A marker containing Mcm7 gene is provided to measure expression level of Mcm7 gene and protein and to early diagnose liver cancer. CONSTITUTION: A marker for diagnosing distoma sinensis infection or liver cancer contains Mcm7 gene having a base sequence of sequence number 1. A kit for diagnosing distoma sinensis infection or liver cancer contains Mcm7 gene. The kit also contains sense and antisense primer of the Mcm7 gene, a complementary probe to Mcm7 gene, and an antibody which is specific to Mcm7 gene.
