Abstract:
PURPOSE: An increase method of fused protein into living cells or organs by adding levosulpiride to fused protein in which protein transport domains and therapeutic protein are covalently bonded is provided to increase therapeutic effects of protein medicines for various diseases. CONSTITUTION: An increase method of fused protein into living cells or organs is processed by adding levosulpiride to fused protein in which protein transport domains and therapeutic protein are covalently bonded. The levosulpiride is primarily processed in the living cells or organs than the fused protein. A protein transport domain is Tat, PEP-1, oligolysine, oligo arginine or oligo(lysine and arginine). The therapeutic protein is rpS3. A composition for preventing and treating inflammatory diseases comprises fused proteins in which is covalently bonded with the protein transport domain and levosulpiride. The inflammation therapeutic protein is rpS3. A composition for preventing and improving skin external application comprises fused proteins in which is covalently bonded with the protein transport domain and levosulpiride.
Abstract:
PURPOSE: A composition containing cell transducing rpS3 fusion protein is provided to smoothly deliver the protein into skin cells and to effectively suppress inflammation. CONSTITUTION: A pharmaceutical composition for preventing and treating skin inflammatory diseases contains cell transducing rpS3 fusion protein as a main ingredient. The fusion protein has a non-hyphophilic domain containing 5 or more tryptophane, a hydrophilic domain containing 4 or more lysine, and protein transduction domain with a spacer which divides two domains. A cosmetic composition for treating skin inflammation contains 15-30 amino acids.
Abstract:
파킨슨병은 뇌의 흑색질 내에서 도파민 뉴런이 점차 상실되는 신경퇴행성 질환이다. 리보솜 단백질 S3 (rpS3)는 단백질 합성, 항산화 및 UV 엔도뉴클리에이즈 Ⅲ 활성과 같은 다양한 기능을 수행한다. 본 발명자들은 앞선 연구에서 PEP-1-rpS3 융합단백질이 피부염증을 억제하고 뇌허혈 손상에서 신경보호효과를 나타냄을 밝혔다. 본 발명자들은 PEP-1-rpS3 융합단백질이 SH-SY5Y 신경아세포종 세포 및 파킨슨병 동물모델에서 산화 스트레스로부터 도파민 뉴런을 보호할 수 있음을 밝혀내었다. PEP-1-rpS3 융합단백질은 SH-SY5Y 세포 내로 그리고 뇌의 흑색질 내로 잘 이동함을 웨스턴 블랏 분석으로 확인하였다. PEP-1-rpS3 융합단백질은 MPP + 로 유도되는 활성산소종 생성 및 DNA 조각화를 현저히 저해하였으며, 결과적으로 SH-SY5Y 세포의 생존을 유도했다. 신경보호 효과는 PEP-1-rpS3 융합단백질이 친-자기세로사멸 매개자 및 항-자기세포사멸 매개자의 수준에 영향을 미침으로써 얻어진다. 나아가, TH 항체 및 크레실 바이올렛 염색을 이용한 면역조직화학 분석 데이타는 PEP-1-rpS3 융합단백질이 MPTP와 같은 산화 스트레스에 대하여 흑색질 내의 도파민 세포를 현저히 보호함을 나타낸다. 따라서, PEP-1-rpS3 융합단백질은 파킨슨병의 예방 및 치료 용도로 이용 가능하다.
Abstract:
PURPOSE: A pharmaceutical composition containing PEP1-1-rpS3 fusion proteins for preventing and treating Parkinson's disease is provided to remarkably protect dopaminergic cells of substantia nigra from oxidative stresses such as 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). CONSTITUTION: A pharmaceutical composition for preventing and treating Parkinson's disease contains rpS fusion proteins which are prepared by covalent bond of a protein transport domain at N-terminal and/or C-terminal of rpS protein. The protein transport domain is selected among: a protein transport domain comprising a hydrophobic domain which consists of 15-30 amino acids containing 5 or more tryptophan, hydrophilic domains with four or more lysine, and a spacer which separates two domains; an oligolysine protein transport domain which consists of 6-12 lysine; an oligoarginine protein transport domain which consists of 56-12 arginine; and oligo (lysine, arginine) protein transport domain which consists of 6-12 lysine or arginine.
