Abstract: The present disclosure provides a new protocol for sequencing the 3? end of messenger RNA (mRNA). The present disclosure can be very favorably used in analyzing the repetitive sequences of nucleic acids, which are difficult to analyze by current sequencing methods, especially, homopolymeric sequences (poly[A] sequence) of mRNA. The present disclosure has significantly improved sensitivity to mRNA compared with an existing method, thereby obtaining a lot of genetic information from a small amount of sample. The method of the present disclosure reduces the time and cost for sequencing the 3? end of mRNA and can be applied to various samples, and thus, can be used as a useful tool in the study of RNA synthesis/degradation and protein production in association with all life phenomena, including embryogenesis, cancer, and neurotransmission.

Abstract: The present invention relates to a phosphatidylinositol 3-kinases activity regulator which include the fifth zinc finger domain of FOG2 and which, more specifically, can induce cancer cells to die due to the inclusion of the fifth zinc finger domain of FOG2. Since the death of cancer cells is induced by suppressing the transfer of PI3K signals, the fifth zinc finger domain of FOG2 according to the present invention can be suitably use as a composition for the prevention and treatment of PI3K-related diseases.

Abstract: The present invention relates to a miRNA regulating the insulin signaling pathway, and to a method for screening a material for controlling the action of a target gene thereof, and particularly, to a method for screening a material for controlling the action of USH or FOG2, a target gene of miR-8 or miR-200 miRNA for promoting cell growth. The present inventors discovered miR-8, a conserved miRNA for regulating the body of a fruit fly by targeting u-shaped material (USH) in the fat cells of Drosophila. It was also confirmed that a target gene of miR-200, a human homologous gene of Drosophila miR-8 miRNA, is FOG2. It was found that Drosophila miR-8 and USH are also conserved in mammals, and FOG2, a human homologous gene of USH, directly binds to a regulating subunit of PI3K and functions. It was confirmed that when the expression of miR-200 is inhibited or FOG2 is expressed in a human cancer cell line, the activity of PI3K, which promotes cell growth, is decreased.

Abstract: The present invention relates to an amphiphilic peptide capable of promoting target miRNA production and a method for regulating the production of target miRNA using the same. In detail, the amphiphilic peptide of the present invention binds strongly and specifically to hairpin-shaped target miRNA. The specific binding affinity induces the Dicer enzyme activity, therefore specifically increase the production of target miRNA. The present invention can be effectively used for regulating the amount of target miRNA produced in vivo, for the study of miRNA functions and for producing therapeutic drug for target miRNA related disease.
