Cardiac apoptosis have two major apoptotic pathways, Fas death receptor-dependent and mitochondria-dependent apoptotic pathways. However, Effects of endothelin type A receptor antagonist and exercise therapy on sleep apnea-induced Cardiac apotosis is still totally unknown. The first year: To further clarify the effects of endothelin Type A receptor antagonist pathways of cardiac apoptosis in sleep apnea. There are four group [G1: normoxia Control (n=20); G2: Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20); G3: Endothelin Type A receptor antagonist BQ-123 (100 nmol.kg(-1).day(-1) sc for 14 days) + Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20); G4: Endothelin Type A receptor antagonist BQ-123 (1000 nmol.kg(-1).day(-1) sc for 14 days) + Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20)]. Blood pressure, Type I cardiac apoptosis (Fas ligand, Fas Death-receptor, caspase 8, and caspase 3) and Type II cardiac apoptosis (Bcl2 family proteins-Bcl2, BNIP3, Bad, cytochrome c release,caspase 9, and caspase 3), and PI3K-Akt survival signaling pathways in there four groups will be measured by tail cuff measurement, multiple experimental methods related cardiac apoptosis such as cross section, H&E staining, TUNEL assay, western blotting, and RT-PCR. The second year: To determine the effects of exercise therapy on cardiac apoptosis in Sleep apnea. There are three group [G1: normoxia Control (n=20); G2: Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20); G3: Swimming training (Pre-conditioning 14 days+ conditioning 14 days) + Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20)]. Blood pressure, cardiac Fas and mitochondria dependent apoptotic and PI3K-Akt survival signaling pathways will be measured by multiple experimental methology such as cross section, hematoxylin and eosin staining, TUNEL assay, western blotting, and RT-PCR. The third year: To determine the effects of exercise training on cardiac apoptosis in type II DM. There are five group [G1: normoxia Control (n=20); G2: Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20); G3: Endothelin Type A receptor antagonist BQ-123 (100 nmol.kg(-1).day(-1) sc for 14 days) + Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20); G4: Swimming training (Pre-conditioning 14 days+ conditioning 14 days) + Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20); G5: Swimming training (Pre-conditioning 14 days+ conditioning 14 days) +Endothelin Type A receptor antagonist BQ-123 (100 nmol.kg(-1).day(-1) sc for 14 days) + Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20)]。Blood pressure, cardiac Fas and mitochondria dependent apoptotic and PI3K-Akt survival signaling pathways will be measured by metabolic treadmill, tail cuff measurement, and multiple experiments related cardiacapoptosis such as cross section, H&E staining, TUNEL assay, western blotting, and RT-PCR.2008 年在Am J Physiol Heart Circ Physiol 期刊提出Endothelin type A receptor antagonist 改善睡眠呼吸終止症(夜間漸歇性缺氧)的老鼠的血壓和心血 管的傷害(Allahdadi et al., 2008)。心臟細胞凋亡途徑可分為Fas death receptor-及 mitochondria- dependent 兩種主要途徑,然而是否內皮素A 型受體拮抗劑或運動 治療對睡眠呼吸終止症(夜間漸歇性缺氧)中心臟細胞Fas& Mitochondrial 凋亡途 徑的療效,至今仍未知。 第一年計劃: 為了探討內皮素A 型受體拮抗劑對睡眠呼吸終止症(夜間漸歇 性缺氧)中心臟細胞Fas& Mitochondrial 凋亡和PI3K-Akt 存活途徑途徑的影響。 實驗共分成four group [G1: normoxia Control (n=20); G2: Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20); G3: Endothelin Type A receptor antagonist BQ-123 (100 nmol.kg(-1).day(-1) sc for 14 days) + Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20); G4: Endothelin Type A receptor antagonist BQ-123 (1000 nmol.kg(-1).day(-1) sc for 14 days) + Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20)] 進行血壓、多重凋亡相關實驗 法例如組織切片、TUNEL assay、western blotting、RT-PCR 等實驗方法來加以分 析並加以探討其心肌細胞凋亡的現象,Fas death receptor-dependent 心肌細胞凋亡 (Fas ligand, Fas Death-receptor, caspase 8, and caspase 3)和mitochondria-dependent 心肌細胞凋亡(Bcl2 family proteins-Bcl2, BNIP3, Bad, cytochrome c release, caspase 9 and caspase 3)和PI3K-Akt 等訊息傳遞路徑。 第二年計劃:為了探討運動治療對睡眠呼吸終止症(夜間漸歇性缺氧)對於心 臟細胞抗凋亡和PI3K-Akt 存活途徑的療效,因此本實驗第二年計劃將three group [G1: normoxia Control (n=20); G2: Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20); G3: Swimming training (Pre-conditioning 14 days+ conditioning 14 days) + Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20)] 進行血壓、多重凋亡相關實驗法例如組織切片、western blotting、 TUNEL assay, RT-PCR 等實驗方法來加以分析並加以探討其心肌細胞凋亡的現 象,Fas death receptor-dependent 心肌細胞凋亡(Fas ligand, Fas Death-receptor, caspase 8, and caspase 3)和mitochondria-dependent 心肌細胞凋亡(Bcl2 family proteins-Bcl2, BNIP3, Bad, cytochrome c release, caspase 9 and caspase 3) 和 PI3K-Akt 等訊息傳遞路徑。 第三年計劃:為了探討內皮素A 型受體拮抗劑配合運動治療是否加乘對睡眠 呼吸終止症(夜間漸歇性缺氧)對於心臟細胞抗凋亡和PI3K-Akt 存活途徑之療 效,因此本實驗第三年計劃將將分五組[G1: normoxia Control (n=20); G2: Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20); G3: Endothelin Type A receptor antagonist BQ-123 (100 nmol.kg(-1).day(-1) sc for 14 days) + Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20); G4: Swimming training (Pre-conditioning 14 days+ conditioning 14 days) + Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20); G5: Swimming training (Pre-conditioning 14 days+ conditioning 14 days) +Endothelin Type A receptor antagonist BQ-123 (100 nmol.kg(-1).day(-1) sc for 14 days) + Intermittent hypoxia (2 min N2 + 2min normoxia, 8 hour, 2 weeks, n=20)]。加以探討其血壓、Fas 和 mitochondria-dependent 心肌細胞凋亡和PI3K-Akt 存活途徑的現象。內皮素A型受體拮抗劑配合運動治療對睡眠呼吸終止症誘發心臟細胞凋亡的療效探討Project
