미토콘드리아 E3 유비퀴틴 리가제(Mitochondrial E3 Ubiquitin Ligase)인 MARCH5(MITOL이라고도 알려짐)는 유비퀴틴화(ubiquitylation)를 통하여 미토콘드리아 형태 조절 단백질을 조절한다. MARCH5는 미토콘드리아 다이나믹스(dynamics) 단백질인 hFis1 및 Mfns(Mfn1,2)을 조절하고, Drp1을 세포질(cytosol)로부터 미토콘드리아로 이동시킨다. 최근 연구에 의하면, MARCH5는 돌연변이 수퍼옥사이드 디스뮤타제 1(superoxide dismutase 1; mSOD1)의 미토콘드리아 축적에 의해 야기되는 미토콘드리아 기능 장애에 대응한 방어적 역할을 수행하는 것으로 나타났다. 잘못 접힌(misfolded) mSOD1은 심각한 신경퇴행성 질환인 루게릭병(amyotrophic lateral sclerosis; ALS) 환자의 신경 세포에 축적되는 것으로 나타났다. 또한, MARCH5는 미토콘드리아에 축적되고 미토콘드리아 기능 장애를 유발하는 폴리글루타민-확장 단백질(polyglutamine-expanded protein; PolyQ)에 대한 세포 독성을 조절한다고 밝혀졌는데, PolyQ는 헌팅턴병, 마카도 조셉병(machado joseph disease) 또는 척수소뇌성 실조증(spinocerebellar ataxia)과 같은 질병에 관련되어 있는 것으로 알려져 있다.
Mitochondrial E3 Ubiquitin Ligase MARCH5 (also known as MITOL) regulates mitochondrial morphogenetic proteins through ubiquitination. MARCH5 regulates the mitochondrial dynamics proteins hFis1 and Mfns (Mfn1,2) and moves Drp1 from the cytosol to the mitochondria. Recent studies have shown that MARCH5 plays a protective role in mitochondrial dysfunction caused by mitochondrial accumulation of mutant superoxide dismutase 1 (mSOD1). Misfolded mSOD1 has been shown to accumulate in neurons in patients with severe neurodegenerative disease amyotrophic lateral sclerosis (ALS). In addition, MARCH5 has been shown to regulate cytotoxicity against polyglutamine-expanded protein (PolyQ), which accumulates in mitochondria and causes mitochondrial dysfunction. PolyQ has been shown to inhibit Huntington's disease, machado joseph disease, Or spinocerebellar ataxia. ≪ RTI ID = 0.0 > [0004] < / RTI >

1. 세포 배양1. Cell culture

본 발명에 사용한 세포는 ATCC (the global biosource center; atcc.org)에서 구매하여 사용하였으며, 293T 세포와 Mouse leukaemic monocyte macrophage (Raw264.7) 모두 DMEM high glucose (Dulbecco's modified Eagle's medium; Gibco) 배지에 10% 우태아혈청(fetal bovine serum)과 1% 페니실린-스트렙토마이신(penicillin-streptomycin) 항생제를 첨가하여 37℃, 5% CO2 배양기에서 세포를 배양하였다.
The cells used in the present invention were purchased from ATCC (the global biosource center; atcc.org), and 293T cells and mouse leukemic monocyte macrophages (Raw264.7) were cultured in DMEM high glucose (Dulbecco's modified Eagle's medium; Gibco) Fetal bovine serum and 1% penicillin-streptomycin antibiotics were added and the cells were cultured at 37 ° C in 5% CO 2 Cells were cultured in an incubator.

2. 형질감염(transfection) 및 면역블롯팅(immunoblotting)2. Transfection and immunoblotting.

MARCH5 siRNA [5'-CUCAUCCUGACGAGUCUGU-3'(서열번호 3) 및 5'-CUGAUACUAGGCAAAAUGA-3'(서열번호 4)]를 Opti-MEM media에 리포펙타민(lipofectamin) 2000 (invitrogen)과 배양시킨 뒤, 3시간 후에 배지를 새로운 것으로 교체하고 48시간 배양하여, 형질감염(transfection)을 유도하였다.The MARCH5 siRNA [5'-CUCAUCCUGACGAGUCUGU-3 'and 5'-CUGAUACUAGGCAAAAUGA-3' (SEQ ID NO: 4) were cultured on Opti-MEM media with lipofectamine 2000 (Invitrogen) After 3 hours the medium was replaced with fresh and incubated for 48 hours to induce transfection.

형질감염하여 단백질 발현이 줄어든 것을 면역블롯팅(immunoblotting)으로 확인하였는데, 세포를 트립신(trypsin)을 이용하여 모은 뒤, 1x 단백질 sample buffer로 direct lysis하여 얻어진 단백질을 폴리아크릴아마이드 젤에 전기영동한 후에, NC(nitrocellulose membrane)로 옮겼다. 얻어진 NC blot을 5% non-fat milk를 포함한 TBST buffer에 1시간 동안 블로킹(blocking) 한 후, 각각의 1,2차 항체를 각각 반응(incubation)시킨 뒤, ECL(enhanced chemiluminescence systeme)을 이용하여 단백질 발현을 확인하였다.  After the cells were collected using trypsin, direct lysis was performed with a 1x protein sample buffer, and the resulting protein was electrophoresed on a polyacrylamide gel. The protein was then analyzed by immunoblotting , And transferred to a nitrocellulose membrane (NC). The resulting NC blot was blocked in TBST buffer containing 5% non-fat milk for 1 hour, incubated with each of the first and second antibodies, and then subjected to ECL (enhanced chemiluminescence system) Protein expression was confirmed.

THP-1 세포에 control siRNA, MARCH5 siRNA를 발현시킨 뒤, GFP를 발현하는 수포성 구내염 바이러스(Vesicular stomatitis virus; VSV)와 H1N1 인플루엔자 바이러스(H1N1 influenza virus; A/PR8/8/34)를 바이러스를 감염시킨 뒤 형광으로 바이러스의 감염 정도를 측정하고, 형광을 스캔닝(scanning)하여 그 양을 정량적으로 측정하였다. After expressing control siRNA and MARCH5 siRNA in THP-1 cells, viruses such as Vesicular stomatitis virus (VSV) expressing GFP and H1N1 influenza virus (A / PR8 / 8/34) After infecting, the degree of infection of the virus with fluorescence was measured, and the amount of fluorescence was quantitatively measured by scanning.

바이러스 감염 과정은 다음과 같다. GFP-tagged VSF와 H1N1 인플루엔자 바이러스는 세포에서 증폭시켰으며, standard plaque assay를 통해서 정량하였다. GFP 발현은 Fluorescence module of GloMax®-Multi Microplate Multimode Reader (Promega, E7031)를 통해서 디지털화하여 수치로 확인하였다. 바이러스 감염은 배양 배지를 혈청이 없는 DMEM 배지로 감염 직전에 교체해준 뒤, 바이러스를 원하는 MOI 만큼 배지에 직접 첨가하여 주었다. 2시간 후에, 배지를 교체하여 세포밖에 있는 바이러스를 제거하여주었다.
The virus infection process is as follows. GFP-tagged VSF and H1N1 influenza virus were amplified in cells and quantitated by standard plaque assay. GFP expression was digitized and quantified using the Fluorescence module of the GloMax®-Multi Microplate Multimode Reader (Promega, E7031). Viral infections were induced by replacing the culture medium with serum-free DMEM medium immediately before infection, and then adding the virus directly to the medium as much as the desired MOI. Two hours later, the medium was replaced to remove the virus outside the cells.

세포를 상층액과 분리(cell down)시킨 후 상층액을 따서 보관하였다. 펠렛(pellet)에 DMEM 200ul를 넣고 -75℃에서 얼린 후 37℃에서 녹이는 과정을 5번 반복하였다. 12000rpm, 5min으로 원심분리한 후 상층액을 상기에 보관했던 상층액과 섞어서 보관하였다. 12 well에 293T 세포를 깔아주고, 상기 보관했던 바이러스가 포함된 상층액을 1/10, 1/100, 1/1000으로 희석하여 12 well에 2~3시간 감염시켰다. 2% 아가(aga) 10ml과 2×DMEM을 섞어서 12 well에 있는 배지 제거 후에 1ml 씩 넣어준 후 상온에서 20분 정도 굳혔다. 37℃에서 24h 배양시킨 후 플라크(plaque)를 계수하였다.
The cells were separated from the supernatant (cell down) and stored in supernatant. 200 ul of DMEM was added to the pellet, and the mixture was frozen at -75 ° C and then dissolved at 37 ° C for 5 times. After centrifugation at 12,000 rpm for 5 min, the supernatant was mixed with the supernatant stored in the supernatant. 293T cells were plated in 12 wells, and the virus-containing supernatant was diluted to 1/10, 1/100 and 1/1000, and infected in 12 wells for 2-3 hours. 2 ml of agar and 10 ml of 2 × DMEM were added to each well. After removing the medium from the wells, 1 ml of the medium was added and the mixture was allowed to stand at room temperature for 20 minutes. After incubation at 37 ° C for 24 h, plaques were counted.

MARCH5 단백질을 siRNA를 이용하여 THP-1 세포 내에서 발현량을 저하시켰을 때, 단백질 발현수준이 현저하게 감소한 것을 확인하였으며(도 1A), control siRNA 또는 MARCH5 siRNA를 세포에 형질감염(transfection) 시킨 후, GFP가 태깅(tagging) 되어져 있는 PR8-gfp 바이러스와 VSV-gfp를 감염(infection) 시킨 후 바이러스의 증식을 GFP를 통해 관찰하였다. 이때, MARCH5를 세포 내에서 발현 저하시킨 실험군에서 바이러스의 증식이 감소한 것을 관찰하였다(도 1B). 바이러스의 증식을 플라크 분석(planqe assay)을 통해 정량검사한 결과, MARCH5 발현저하 실험군에서 바이러스 증식이 감소한 것을 관찰하였고, GFP의 발현량을 정량적으로 수치화 시킨 그래프에서도 바이러스의증식이 감소한 것을 관찰하였다(도 1C).When the expression level of MARCH5 protein was lowered in THP-1 cells using siRNA, the level of protein expression was markedly decreased (Fig. 1A). After transfection of control siRNA or MARCH5 siRNA into cells , And the proliferation of the PR8-gfp virus and VSV-gfp tagged with GFP was observed through GFP. At this time, it was observed that virus proliferation decreased in the experimental group in which MARCH5 expression was decreased in the cells (Fig. 1B). Quantitative analysis of viral proliferation by a planqe assay showed that virus growth was reduced in the MARCH5 expression-lowering experimental group and that in the graph quantitatively quantifying the expression level of GFP, virus proliferation was reduced 1C).

도 1에서와 같은 방법으로 RAW264.7 세포에서도 바이러스의 증식을 조사하였다. MARCH5 siRNA를 이용하여 세포 내에서 단백질 발현을 감소시킨 후, 단백질 양이 성공적으로 감소한 것을 관찰하였다(도 2A). PR8-gfp, VSV-gfp 바이러스를 control siRNA, MARCH5 siRNA를 각각 발현시킨 뒤 감염시키고, 바이러스의 증식을 GFP로 관찰하였다. 이때, MARCH5를 발현 저하시킨 실험군에서 바이러스의 증식이 현저하게 감소하여 있었으며, 정량화한 후 그래프화 시켰을 때에도 역시 감소한 것을 관찰할 수 있었다(도 2B). 또한, MARCH5 발현이 저하된 세포에서 바이러스의 증식에 대해 플라크 분석(planqe assay)를 실시한 결과 control siRNA를 발현시킨 실험군에 비해 바이러스의증식이 감소된 것을 관찰하였다(도 2C).
Virus growth was also examined in RAW264.7 cells by the same method as in Fig. After the protein expression was reduced in the cells using MARCH5 siRNA, the protein amount was observed to be successfully decreased (Fig. 2A). PR8-gfp and VSV-gfp viruses were transfected with control siRNA and MARCH5 siRNA, respectively, and the proliferation of viruses was observed with GFP. At this time, virus proliferation was remarkably decreased in the experimental group in which expression of MARCH5 was decreased, and it was also decreased when quantified and then graphed (FIG. 2B). In addition, a planqe assay for the proliferation of viruses in cells with decreased MARCH5 expression showed that virus proliferation was reduced as compared with the control siRNA-expressing experimental group (Fig. 2C).
