摘要

Brusein-A有望引起细胞凋亡。胱天蛋白酶-3是参与细胞凋亡过程的蛋白质之一。本研究旨在确定brusin-A对乳腺癌症组织中半胱氨酸天冬氨酸蛋白酶-3表达的抗癌活性。研究采用完全随机设计。多达27只12周大的雌性大鼠通过口服途径给予20mg/kgBB二甲基苯并蒽(DMBA)3周,直到乳腺癌症。其次,将brusin-A分为9个治疗组,均为0;2.5;5.7.5;10;12.5;15;17.5;20mg/L,持续28天。测量的参数是基于巧克力色谷蛋白浆的百分比评估的胱天蛋白酶-3表达。这项研究于2015-2016年在科学技术研究中心病理解剖学和实验室生物化学实验室Serp进行。该研究显示,在0 mg/L、2.5 mg/L、5 mg/L、21%、7.5 mg/L、25%、10 mg/L、12.5 mg/L、65%、15 mg/L、75.3%、17.5 mg/L和20 mg/L的剂量下,胱天蛋白酶-3的表达率分别为4%、15.3%、21%、25%、41%、65%、65%、75%。单因素方差分析结果显示组间胱天蛋白酶-3平均显著治疗差异(p=0.0001)。Spearman相关性试验显示,brusin-a的剂量与胱天蛋白酶-3的表达之间存在非常密切的正相关关系(r=0.994)。Simpulan,brusin-A在DMBA诱导的乳腺癌症上增强胱天蛋白酶-3的表达。BRUSEIN-A给药后乳腺癌大鼠的CASPASE-3表达被认为会引起细胞凋亡。Caspase-3是一种在细胞凋亡过程中发挥作用的蛋白质。本研究旨在确定刷蛋白A对乳腺癌组织中胱天蛋白酶-3表达的抗癌活性。本研究采用完全随机对照设计。共27只12周龄的雌性大鼠口服20 mg二甲基苯并蒽(DMBA)/kgBW,持续3周,直到它们患上癌症。他们分为9个治疗组,分别为0、2.5、5、7.5、10、12.5、15、17.5和20mg/L,持续28天。测量的参数是胱天蛋白酶-3的表达,根据棕色细胞质的百分比进行评估。本研究于2015-2016年在Serpong科学技术研究中心病理解剖实验室和生物化学实验室进行。结果表明,在2.5、5、7.5、10、12.5、15、17.5和20mg/L的剂量下,caspase的表达率分别为4%、15.3%、21%、25%、41%、65%、75.3%、84%和94.7%。单因素方差分析结果显示,治疗组间半胱氨酸天冬氨酸蛋白酶-3的表达存在显著差异(p=0.0001),Spearman秩相关检验显示,brusein-a剂量与半胱氨酸天冬氨酶-3的表达之间存在非常密切的正相关关系(r=0.994)。

Ekspresi Caspase-3 pada Kanker Payudara Tikus Setelah Pemberian Antikanker Brusein-A
Brusein-A diduga menyebabkan apoptosis. Salah satu protein yang berperan dalam proses apoptosis adalah caspase-3 . Penelitian ini bertujuan mengetahui aktivitas antikanker brusein-A terhadap ekspresi caspase-3 pada kanker payudara. Penelitian menggunakan rancang acak lengkap.
