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.
Abstract:
본 발명은 세포사멸을 유도하는 방법 및 이를 이용한 세포사멸 유도용 약학 조성물을 제공하고자 하며, 보다 구체적으로 SET 도메인을 함유한 단백질을 과발현시키면 이의 HMTase 활성에 의해 전사가 활성화되고 세포사멸과 관련된 유전자들이 조절되어 세포 생존력을 낮추므로, 본 발명에서는 SET 도메인을 함유한 단백질을 과발현시켜 세포사멸을 유도하는 방법을 제공하며, 또한 세포사멸을 유도함으로 암, 당뇨병, 관절염, 염증성 장 질환, 죽상동맥경화증, 자가면역 질환, 이식 거부, 외상후 면역 반응, 감염성 질환, 림프계 종양, 림프종, 다발성 경화증, 전신 홍반성 루프스, 경피증, 허혈, 뇌졸중, 포도막염 또는 당뇨 망막증을 예방 및 치료에 본 발명의 조성물이 제공될 수 있다.
Abstract:
The present invention relates to a transcriptional regulation method of a gene using combination of SET/TAF-Ibeta and methylated H3K27, and the combination of SET/TAF-Ibeta and methylated H3K27 is inhibited by phosphorylation of HEK28, thereby inducing activation or suppression of gene transcription. Through such a transcriptional regulation mechanism, transcription of a SET/TAF-Ibeta target gene can be regulated so that a gene transcriptional regulation method of the present invention can be effectively used for research of the transcriptional regulation mechanism and artificial gene expression regulatory using the same.
