Description
본 발명은 심혈관 질환 예방 또는 치료용 조성물에 관한 것으로, 보다 구체적으로는 p32 저해제를 유효성분으로 포함하는 심혈관 질환 예방 또는 치료용 조성물에 관한 것이다.The present invention relates to a composition for preventing or treating cardiovascular diseases, and more particularly, to a composition for preventing or treating cardiovascular diseases, which comprises a p32 inhibitor as an active ingredient.
생체 내에서 혈액은 복잡하고 정교한 조절 시스템에 의해 항상 평형을 이루고 있어 정상적인 상태에서는 출혈이나 혈전 등에 의해 흐름이 방해받지 않는다. 그러나 여러 가지 요인으로 이러한 평형상태가 깨지면 혈관의 흐름이 원활하지 못하여 혈관 질환들이 발생하게 된다. 혈관질환 중 가장 대표적인 경우가 동맥경화증인데, 심장이나 뇌 등 중요장기에 허혈성 상태를 초래하여 심근경색이나 뇌경색을 일으키는 매우 위험한 질환 중 하나이다.In vivo, the blood is always balanced by a complex and elaborate regulatory system, so that the flow is not interrupted by bleeding or thrombosis under normal conditions. However, when the equilibrium state is broken due to various factors, the flow of blood vessels is not smooth and blood vessel diseases occur. The most common type of vascular disease is arteriosclerosis, which is one of the most dangerous diseases that cause myocardial infarction or cerebral infarction by causing ischemic conditions in important organs such as the heart and brain.
한편, 심장과 혈관은 전신에 산소와 영양소를 공급하는 기관으로 인간이 생명을 유지하는데 없어서는 안 되는 핵심기관이라 할 수 있다. 따라서 여러 가지 원인으로 심혈관계에 이상이 생겨 각 조직 및 기관으로의 혈액과 산소공급이 원활하지 못할 경우 국소부위 조직괴사는 물론 심한 경우 생명에 위협을 주는 위험한 질환을 야기하게 된다. 심혈관 질환은 특히 나이가 들어감에 따라 인체의 노화 현상으로 더욱 빈번해진다. 이러한 이유로 심혈관질환의 예방과 치료가 매우 중요해지고 있다.On the other hand, the heart and blood vessels supply oxygen and nutrients to the whole body, which is an essential part of human life. Therefore, if blood and oxygen supply to each tissue or organ is not smooth due to various causes of cardiovascular diseases, it may cause dangerous disease which threatens to life as well as local necrosis of tissue. Cardiovascular disease is becoming more frequent as a result of aging of the human body, especially as it gets older. For this reason, prevention and treatment of cardiovascular diseases is becoming very important.
혈관근육세포(vascular smooth muscle cells)는 혈관을 형성하는 핵심세포로 수축과 이완을 통해 혈압을 조절하는 데 필수적인 역할을 하며 혈관평활근세포라고도 불린다. 이러한 혈관근육세포의 비정상적 증식은 고혈압, 동맥경화 등 심혈관질환의 원인이 된다. 혈관근육세포의 증식은 평활근세포 자체 및 내막세포, 대식세포, 혈소판 등에서 분비되는 자가분비(autocrine)와 측분비 성장인자(paracrine growth factor)에 의해 조절된다. 혈관근육세포의 증식에 관련된 성장인자로서는 대표적으로 platelet-derived growth factor(PDGF), basic fibroblast growth factor(bFGF)가 있으며, 혈관근육세포의 이상증식을 억제할 수 있다면 고혈압, 동맥경화, 심혈관계 질환, 이의 합병증과 같은 질환의 치료와 예방에 우수한 효과를 얻을 것으로 예상되며 현재 이에 대한 많은 연구가 진행되고 있다.Vascular smooth muscle cells (vascular smooth muscle cells) are essential cells that regulate blood pressure through contraction and relaxation and are called vascular smooth muscle cells. Such abnormal proliferation of blood vessel muscle cells causes cardiovascular diseases such as hypertension and arteriosclerosis. The proliferation of vascular myocytes is regulated by autocrine and paracrine growth factors secreted by smooth muscle cells and endothelial cells, macrophages, and platelets. There are platelet-derived growth factor (PDGF) and basic fibroblast growth factor (bFGF) as growth factors involved in the proliferation of blood vessel myocytes. If they can inhibit abnormal proliferation of blood vessel muscle cells, , And its complications, and many studies are under way.
현재까지 심혈관 질환의 치료제로 질산(Nitrate)계 제제인 슈와즈(Schwarz)사의 ISMO 등이 소개되어 있으나, 이 제제는 효과는 뛰어나나 체위성저혈압, 심계항진 등의 부작용이 있어, 저혈압, 녹내장 등의 환자에게는 신중히사용해야 하며, beta-차단제로 아스트라(Astra)사의 베타록(BETALOC)등이 소개되어 있는데, 이 제제 역시 효과는 확실하나 급격한 심장억제 등으로 울혈성심부전환자 등은 신중히 사용해야 한다.To date, the ISMO of Schwarz has been introduced as a treatment for cardiovascular disease. However, this formulation has excellent effects and has side effects such as hypotension and palpitations. Therefore, hypotension, glaucoma, etc. (BETALOC) as a beta-blocker. This formulation is also effective, but patients with congestive heart failure should be used with caution due to rapid cardiac suppression.
한편, 내피 산화질소의 정상적인 생성은 혈관 기능의 유지를 위해 중요하다. 내피세포의 산화질소 방출이 증가하면 평활근(smooth muscle) 세포의 신축성 감소 및 저하된 혈관 저항(vascular resistance)을 초래한다. 그러나 고혈압 및 고지혈증의 상태 하에서 내피의 기능이상은 산화질소 방출의 현저한 감소를 발생시키며, 그 결과로 혈관수축 및 혈관경련이 증가되며, 단핵세포 및 LDL 침윤의 확대되고, 혈관 평활근 세포가 증식하며, 산화적스트레스의 증가 및 혈소판 응집의 증가를 초래한다. 따라서 내피의 기능 및 산화질소 대사를 회복시키는 물질은 심장동맥 질환 및 심장 기능 장애가 포함하는 혈관 질환의 치료에 있어서 효과적이라 할 수 있다.On the other hand, normal production of endothelial nitric oxide is important for maintenance of vascular function. Increased release of nitric oxide in endothelial cells leads to decreased elasticity of smooth muscle cells and decreased vascular resistance. However, endothelial dysfunction under hypertensive and hyperlipidemic conditions causes a marked reduction in nitric oxide release, resulting in increased vasoconstriction and vasospasm, increased mononuclear cell and LDL infiltration, proliferation of vascular smooth muscle cells, Leading to increased oxidative stress and increased platelet aggregation. Therefore, endothelial function and substances restoring nitric oxide metabolism are effective in the treatment of vascular diseases including cardiac artery disease and cardiac dysfunction.
산화질소를 합성하는 대부분의 세포들은 아르기나아제(arginase)라는 효소도 갖고 있는데, 아르기나아제는 L-아르기닌(arginine)의 가수분해를 촉매하여 L-오르니틴(ornithine)과 요소(urea)를 생성하는 효소 그룹이다. 아르기나아제 I 은 세포내에서 일정하게(constitutively) 발현되며, 아르기나아제 II는 내독소(endotoxin)에 의해 유도되는 것으로 알려져 있다. 또한 상기 효소들은 염증(inflammatory) 조건에서 산화질소의 생산 변경에 매우 중요한 역할을 하지만, 산화질소의 일정한 합성에도 중요한 역할을 한다.Most of the cells that synthesize nitric oxide also have an enzyme called arginase, which catalyzes the hydrolysis of L-arginine to produce L-ornithine and urea It is an enzyme group to generate. Arginase I is constitutively expressed in cells and arginase II is known to be induced by endotoxin. These enzymes play an important role in the production of nitric oxide under inflammatory conditions, but also play an important role in the synthesis of nitric oxide.
반면, 아르기나아제(arginase)는 또한 공통 기질인 L-아르기닌(Arginine)의 이용을 통해 경쟁적으로 NOS를 저해하는 작용도 한다(Berkowitz et al., 2003; Holowatz et al., 2006; Morris et al., 1998; Peyton et al.,2009; Simon et al., 2003; Steppan et al., 2006). 마크로파지(macrophages), 간세포(hepatocytes) 및 혈관평활근세포(vascular smooth muscle cells)에서 아르기나아제I의 발현 및 기능은 lipopolysaccharide (LPS), IL-13, 변경된 산소분압 및 관상 동맥(coronary arteries)의 풍선확장술(balloon dilatation)에 의해 자극될 수 있으며(Chicoine et al., 2004; Klasen et al., 2001; Louis et al., 1998; Modolell et al., 1995; Morriset al., 2004; Nelin et al., 2007; Que et al., 1998; Ryoo et al., 2006), 또한 아르기나아제 Ⅱ의 활성 및 발현은 OxLDL, LPS, TNF-a, IFN-, 8-bromo-cGMP 및 hypoxia 를 포함한 다양한 혈관 인자들에 의해 유도될 수 있다.On the other hand, arginase also competitively inhibits NOS through the use of a common substrate, L-arginine (Berkowitz et al., 2003; Holowatz et al., 2006; Morris et al Peyton et al., 2009; Simon et al., 2003; Steppan et al., 2006). The expression and function of arginase I in macrophages, hepatocytes and vascular smooth muscle cells was assessed by the expression of lipopolysaccharide (LPS), IL-13, altered oxygen partial pressure and coronary arteries (Nelson et al., 2004), and the effect of the neuronal cell cycle on neuronal cell proliferation was investigated (Chicoine et al., 2004; The activity and expression of arginase II were determined by various methods including OxLDL, LPS, TNF-a, IFN-, 8-bromo-cGMP and hypoxia.

한편 최근 보고된 자료에 의하면 아르기나아제의 억제는 산화질소의 생산을 활발히 증대시키며, 정상적인 심장기능 및 아테롬생성(atherogenesis), 노화, 발기부전 및 겸상 적혈구 빈혈증(sickle cell disease)에서 혈관기능 장애에 유용한 효과를 가져오는 것으로 밝혀진 바 있다(Berkowitz et al., 2003; Bivalacqua etal.,2001; Bivalacqua et al., 2007; Hsu et al., 2007; Morris et al., 2004; Steppan et al., 2006; Whiteet al., 2006; Xu et al., 2007).Recent reports have shown that inhibition of arginase activity can actively increase the production of nitric oxide and is associated with normal cardiac function and atherogenesis, aging, erectile dysfunction and vascular dysfunction in sickle cell disease 2007; Morris et al., 2004; Steppan et al., 2006), which has been shown to have beneficial effects (Berkowitz et al., 2003; Bivalacqua et al., 2001; ; White et al., 2006; Xu et al., 2007).
따라서 아르기나제의 활성을 억제하는 물질의 경우 혈관 기능 장애를 개선 및 치료하는데 유용하게 사용할 수 있을 것으로 예측하고 있으나, 종래 개발된 아르기나제 활성 억제제의 경우, 부작용이 있으며 그 효과도 미비하여 새로운 아르기나제 활성 억제제의 개발이 시급한 실정이다.Therefore, it is predicted that a substance that inhibits the activity of arginase may be useful for improving and treating vascular dysfunction. However, the arginase activity inhibitor conventionally developed has side effects and its effect is insufficient. The development of an arginase activity inhibitor is urgently needed.

아르기나아제를 억제함에 따라 미토콘드리아의 칼슘 농도 증가가 억제되는 것을 확인함에 따라, 본 실시예에서는 아르기나아제 억제가 세포질의 Ca2 +/칼모듈린-의존적 단백질 키나아제(CaMKⅡ)의 인산화를 조절하는지 확인하였다. Arginase, as confirmation that the calcium concentration increased mitochondrial inhibition as inhibiting kinase, in the present embodiment, the arginase inhibitory the Ca 2 + / knife module of the cellular Lin - that regulate the phosphorylation-dependent protein kinase (CaMKⅡ) Respectively.
성장배지에서 배양한 hAoSMC에 nLDL 자극을 각각 다른 시간마다 처리하였다. 그 결과 도 3A를 참조하면, nLDL 자극을 주고나서 10분에 CaMKⅡ의 인산화가 약간 증가하였으나(108±3.6%), 30분 처리시 확실하게 CaMKⅡ 인산화가 감소하였다(56±4.2%). HAoSMC cultured on growth medium were treated with nLDL stimulation at different times. As a result, referring to FIG. 3A, CaMKII phosphorylation was slightly increased at 10 min (108. + -. 3.6%) after nLDL stimulation, but CaMKII phosphorylation was definitely decreased (56. + -. 4.2%) at 30 min treatment.
다음으로, 아르기나아제 억제가 nLDL 자극에 의한 미토콘드리아 칼슘 흡수를 막기 때문에 아르기나아제 억제가 nLDL에 의한 CaMKⅡ 인산화를 회복시킬 수 있는지를 확인하였다. 그 결과 도 3B를 참조하면, 아르기나아제를 억제하는 경우 CaMKⅡ 인산화는 증가하였고(* vs. untreated, 168±11.3 vs. 100±5.1 AU, p<0.01), nLDL에 의한 CaMKⅡ 인산화를 회복시키는 것으로 나타났다(# vs.nLDL only, 97±7.1 vs. 52±4.2, p<0.01). 또한, 도 3C를 참조하면, WT 생쥐에 비해 ArgII-/- 생쥐의 AoSMC에서 CaMKⅡ 인산화가 증가하는 것을 확인하였다(* vs. WT, 142±6.8 vs. 100±11.2, p<0.01).
Next, we confirmed that arginase inhibition could restore CaMKII phosphorylation by nLDL, since arginase inhibition inhibits mitochondrial calcium uptake by nLDL stimulation. As a result, referring to FIG. 3B, CaMKII phosphorylation was increased (* vs. untreated, 168 ± 11.3 vs. 100 ± 5.1 AU, p <0.01) in the case of arginase inhibition, restoring CaMKII phosphorylation by nLDL (# Vs. nLDL only, 97 ± 7.1 vs. 52 ± 4.2, p <0.01). Also, referring to FIG. 3C, it was confirmed that CaMKII phosphorylation was increased in AoSMC of ArgII - / - mice compared to WT mice (* vs. WT, 142 ± 6.8 vs. 100 ± 11.2, p <0.01).

nLDL 의존적 미토콘드리아 칼슘 흡수를 조절하는 칼슘 이동 단백질을 확인하고 미토콘드리아 p32 단백질을 억제하는 안티센스(AS)와 센스(S) 올리고뉴클레오타이드를 제조하였다. AS 올리고뉴클레오타이드를 처리한 hAoSMC는 세포질 내 p32단백질 양의 변화없이 미토콘드리아 p32 단백질을 특이적으로 감소시키는 것으로 나타났다(도 4 참조). 센스와 안티센스 올리고뉴클레오타이드 모두 세포 내로 들어가는 것을 Cy5 파장에서 형광이미지로 확인하였다(도 5 참조). p32 단백질을 억제하는 안티센스 올리고뉴클레오타이드는 nLDL 자극에 의한 미토콘드리아 칼슘 흡수를 억제하였으나(ns), 센스 올리고뉴클레오타이드는 영향을 미치지 않는 것으로 나타났다(도 5 참조, * vs. untreated, p<0.01). 또한, 안티센스 올리고뉴클레오타이드는 nLDL 자극에 의해 감소된 CaMKⅡ 인산화를 회복시키는 것으로 나타났다(도 6 참조).
We have identified antisense (AS) and sense (S) oligonucleotides that inhibit the mitochondrial p32 protein and identify calcium transfer proteins that regulate nLDL dependent mitochondrial calcium uptake. AS oligonucleotide-treated hAoSMC showed a specific decrease in mitochondrial p32 protein without altering the amount of cytoplasmic p32 protein (see FIG. 4). Both the sense and the antisense oligonucleotide enter the cell were confirmed by fluorescence images at the Cy5 wavelength (see FIG. 5). Antisense oligonucleotides inhibiting the p32 protein inhibited mitochondrial calcium uptake by nLDL stimulation (ns), but sense oligonucleotides did not (Figure 5, * vs. untreated, p < 0.01). In addition, the antisense oligonucleotides were shown to restore reduced CaMKII phosphorylation by nLDL stimulation (see FIG. 6).

스페르민이Spermini p32p32 의존적 미토콘드리아의 Dependent mitochondrial CaCa 22 + + 흡수에 따른 Due to absorption CaMKCaMK Ⅱ 인산화에 미치는 효과II phosphorylation
미토콘드리아 p32 단백질이 칼슘 흡수의 원인이고, 아르기나아제 활성이 p32 의존적 미토콘드리아 칼슘 흡수에 영향이 미치는지 여부를 확인하였다. It was determined whether the mitochondrial p32 protein is the cause of calcium uptake and whether arginase activity influences p32-dependent mitochondrial calcium uptake.
먼저, 세포에 올리고뉴클레오타이드를 처리하지 않은 상태에서 폴리아민인 스페르민(spermine), 스페르미딘(spermidine), 푸트레신(putrescine)을 처리하였다. 그 결과, 스페르민(spermine)을 처리하는 경우에만 미토콘드리아 칼슘 농도 증가가 유도되었고(* vs. untreated, 126±8.9 vs. 100±12.5%, p<0.05), 스페르미딘과 푸트레신은 아무런 영향이 없는 것으로 나타났다(도 7 왼쪽 컬럼 참조). First, the cells were treated with the polyamines spermine, spermidine, and putrescine without oligonucleotide treatment. As a result, the increase in mitochondrial calcium concentration was induced only when spermine was treated (* vs. untreated, 126 ± 8.9 vs. 100 ± 12.5%, p <0.05), while spermidine and (See left column of FIG. 7).
또한, 스페르민 의존적 미토콘드리아 칼슘 흡수와 p32 단백질 사이의 관계를 알아보기 위하여, 세포에 안티센스를 전처리하고 폴리아민 자극을 주었다. p32 단백질 억제제인 안티센스 올리고뉴클레오타이드를 처리하는 경우 스페르민에 의해 유도된 미토콘드리아 칼슘 흡수를 억제하였고(도 7 오른쪽 컬럼 참조, 104±5.9 vs. 102±4.6%, ns), 센스 올리고뉴클레오타이드의 처리에 따른 영향은 없는 것으로 나타났다(도 7 가운데 컬럼 참조, * vs. untreated, 106±4.7 vs. 124±5.8%, p<0.01). In addition, to examine the relationship between spermine dependent mitochondrial calcium uptake and p32 protein, cells were pretreated with antisense and given polyamine stimulation. Treatment of the p32 protein inhibitor antisense oligonucleotides inhibited spermine-induced mitochondrial calcium uptake (see column 7, right column, 104 ± 5.9 vs. 102 ± 4.6%, ns), the treatment of the sense oligonucleotides (See column 7 in Figure 7, * vs. untreated, 106 ± 4.7 vs. 124 ± 5.8%, p <0.01).
다음으로, 스페르민이 p32 의존적 미토콘드리아 칼슘 흡수를 유도했기 때문에 CaMKⅡ 인산화에서는 스페르민이 어떠한 영향을 미치는지 확인하였다. 도 8를 참조하면, 스페르민을 처리하는 경우 CaMKⅡ 인산화가 감소하는 것을 확인하였다(* vs. untreated, 25±3.9 vs. 100±5.1 AU, p<0.01).
Next, we examined the effect of spermine on CaMKII phosphorylation because spermine induced p32-dependent mitochondrial calcium uptake. Referring to FIG. 8, it was confirmed that CaMKII phosphorylation was reduced when spermine was treated (* vs. untreated, 25 ± 3.9 vs. 100 ± 5.1 AU, p <0.01).

미오신 L사슬 키나아제(myosin light chain kinase)의 Ca2 +-CaM 의존적 활성과 미오신 L사슬의 인산화는 평활근 수축의 주요한 조절 메커니즘이라는 것은 잘 알려져있다. 본 실시예에서는 대동맥에서 생쥐의 안티센스가 미토콘드리아로 표적되는 p32 단백질의 양을 감소시키는 것을 확인하였다(도 9A 참조). 또한, 센스와 안티센스 올리고뉴클레오타이드가 평활근 세포로 들어갔는지 여부를 내피세포가 제거된 대동맥 혈관에 올리고뉴클레오타이드를 처리하여 대조군과 비교하여 면역형광 이미지로 확인하였다(도 9B 참조). 안티센스 처리군, 센스 처리군, 아무것도 처리하지 않은 대조군에서 페닐에프린(PE)와 노르에피네프린(NE)에 대한 혈관 수축반응을 확인한 결과, 안티센스 처리한 내피세포가 제거된 대동맥은 NE(도 10A 참조, *p<0.01, AS vs. control, 50.5±1.5 vs. 24.3±1.7% in Emax) 와 PE(도 10B참조, *p<0.01, AS vs. control, 73.2±1.9 vs. 44.5±2.8% in Emax) 농도 의존적으로 확실하게 증가하는 것으로 나타났다.
It is well known that Ca 2 + -CaM-dependent activity of myosin light chain kinase and phosphorylation of myosin L chain are the major regulatory mechanisms of smooth muscle contraction. In this example, it was confirmed that the antisense of mice in the aorta reduces the amount of p32 protein targeted to the mitochondria (see Fig. 9A). In addition, whether or not the sense and antisense oligonucleotides were introduced into smooth muscle cells was confirmed by immunofluorescence imaging in comparison with the control group by treating the oligonucleotides with oligonucleotide-depleted aortic blood vessels (see FIG. 9B).

미토콘드리아 칼슘과 증가된 ArgⅡ 활성은 동맥경화와 같은 병리생리학에서 중심적인 역할을 하고 있는 것을 감안하여, 본 실시예에서는 동맥경화 모델인 ApoE-null 생쥐에 고콜레스테롤(HCD) 식이를 하여 p32 단백질의 발현이 어떻게 변화하는지 확인하였다.Considering that mitochondrial calcium and increased ArgII activity play a central role in pathological physiology such as atherosclerosis, in this example, high-cholesterol (HCD) diet was administered to ApoE-null mice, atherosclerotic model, And how it changed.
HCD 식이한 Apo E-null 생쥐의 내피 제거된 대동맥에서 아르기나아제 활성도는 증가하는 것으로 나타났다(도 11A 참조, * vs. WT+NS, 120±1 vs. 100±2%, p<0.01). 또한, HCD 식이한 ApoE-/- 생쥐의 내피 제거된 대동맥에서 아르기나아제의 기질인 L-아르기닌의 농도는 감소하였고(도 11B 참조, * vs. WT+ND, 68.7±10 vs. 100±1%, p<0.01), 생성물인 스페르민(도 11B 참조, spm, # vs. WT+ND, 138.6±0.9 vs. 100±3%, p<0.01), 스페르미딘(도 11B 참조, spmd, # vs. WT+ND, 148.9±5% vs. 100±2%, p<0.01), 푸트레신(도 11B 참조, putr, # vs. WT+ND, 242.7±3% vs. 100±4%, p<0.01)의 농도는 증가하였다. 미토콘드리아 칼슘 농도는 HCD 식이한 ApoE-/- 생쥐에서 분리한 AoSMC에서 증가하였다(도 11C 참조, * vs. WT+ND, 111.8±2 vs. 100±2%, p<0.05). 미토콘드리아 p32 단백질의 발현은 HCD 식이한 ApoE-/- 생쥐의 내피 제거한 대동맥에서 증가하는 것으로 나타났으나(도 11D 참조, * vs. WT+ND, 321±26.1 vs. 100±5.8%, p<0.01), 세포질 내 p32 단백질의 발현은 차이가 없는 것으로 나타났다.
Arginase activity was increased in the endothelial aorta of HCD-fed Apo E-null mice (see Figure 11A, * vs. WT + NS, 120 ± 1 vs. 100 ± 2%, p <0.01). Also, the concentration of L-arginine, an arginase substrate, in the endothelialized aorta of the HCD-type ApoE - / - mice was decreased (see Figure 11B, * vs. WT + ND, 68.7 ± 10 vs. 100 ± 1 11B), spmd (see FIG. 11B, spmd,%, p < 0.01) , vs. WT + ND, 148.9 ± 5% vs. 100 ± 2%, p <0.01), putrescine (see FIG. 11B, putr, # vs. WT + ND, 242.7 ± 3% vs. 100 ± 4 %, p <0.01) was increased. The concentration of mitochondrial calcium was increased in AoSMC isolated from HCD-fed ApoE - / - mice (see FIG. 11C, * vs. WT + ND, 111.8 ± 2 vs. 100 ± 2%, p <0.05). Expression of the mitochondrial p32 protein was increased in the endothelial aorta of the HCD-fed ApoE - / - mice (see FIG. 11D, * vs. WT + ND, 321 ± 26.1 vs. 100 ± 5.8%, p <0.01 ), And there was no difference in expression of cytoplasmic p32 protein.
상기와 같은 결과들을 종합해보면, nLDL-자극된 혈관평활근세포(VSMCs)에서 p32 저해제를 처리해 아르기나아제의 활성을 억제함에 따라 미토콘드리아의 칼슘 농도를 감소시키고, CaMKⅡ의 인산화를 증가시키는 활성을 나타낸다는 것을 알 수 있었다. 또한, 동맥경화 유발 동물모델에서 아르기나아제 활성이 증가하고, L-아르기닌 생산 농도는 감소하고, p32 단백질 발현이 증가하는 것을 통해 혈관 기능 향상과 심장 수축력을 향상시킬 수 있음을 확인할 수 있었다. 따라서 p32 저해제의 처리로 인해 아르기나아제의 활성이 억제되고, 고혈압, 동맥경화, 관상동맥질환, 뇌혈관질환, 말초혈관질환, 대동맥질환 등과 같은 심혈관 질환의 치료제 개발에 유용하게 이용할 수 있음을 확인하였다.
Taken together, these results indicate that the activity of arginase and azathioprine is inhibited by treatment of p32 inhibitors in nLDL-stimulated vascular smooth muscle cells (VSMCs), thereby decreasing the calcium concentration of mitochondria and increasing the phosphorylation of CaMKII . In addition, it was confirmed that arginase activity increased, L-arginine production concentration decreased, and p32 protein expression increased in an arteriosclerosis-inducing animal model, thereby improving vascular function and cardiac contractility. Therefore, it has been confirmed that the treatment of p32 inhibitor inhibits the activity of arginase and is useful for the development of a therapeutic agent for cardiovascular diseases such as hypertension, arteriosclerosis, coronary artery disease, cerebrovascular disease, peripheral vascular disease and aortic disease Respectively.
