Ovarian cancer is a malignant tumor that attacks reproductive organs of women. MicroRNA is known to have an involvement in the prognosis of ovarian cancer. One of them is miR-155-5p which is down regulated and miR-324-5p which is up regulated. Chitosan is used as microRNA delivery system. The aims of this study is to find out the effects of combination microRNA encapsulated chitosan in cell line SKOV3.
Cell line SKOV3 obtained from Stem Cell and Cancer Institute (Kalbe). Mimic miR-155-5p and Antagonist miR-324-5p formulated with chitosan. Total RNA was extracted from nine samples (three as control and six as treatment), and prepared for cDNA synthesis. Expression of RNA and mRNA target was measured using q-PCR Biorad CFX96 C.100 and Gen Ex 7 software. Statistics analysis was measured using SPSS 16.0.
The administration of combination microRNA encapsulated with chitosan affect the expression of miR-155-5p and miR-324-5p endogen (p <0.05). The expression of mRNA target HIF1α and GLI1 was down regulated after treatment. The correlation between expression of microRNA and mRNA target was strongly (p <0.05).
This study successfully presented effects of combination of mimic miR-155-5p and antagonist miR-324-5p encapsulated chitosan which be considered as a potential therapy targets for ovarium cancer.
卵巢癌是一种恶性肿瘤,攻击女性生殖器官。miRNA 已知参与卵巢癌的预后。其中之一是下调的 miR-155-5p 和上调的 miR-324-5p。壳聚糖可用作 miRNA 递送系统。本研究的目的是研究组合 miR-155-5p 和 miR-324-5p 封装壳聚糖在 SKOV3 细胞系中的作用。
从 Stem Cell and Cancer Institute (Kalbe) 获得 SKOV3 细胞系。用壳聚糖制备 mimic miR-155-5p 和 Antagonist miR-324-5p。从 9 个样本(3 个作为对照,6 个作为处理)中提取总 RNA,并制备 cDNA 合成。使用 Biorad CFX96 C.100 和 Gen Ex 7 软件通过 q-PCR 测量 RNA 和 mRNA 靶标表达。使用 SPSS 16.0 进行统计分析。
壳聚糖包封的组合 microRNA 的给药影响内源性 miR-155-5p 和 miR-324-5p 的表达(p <0.05)。治疗后,mRNA 靶标 HIF1α 和 GLI1 的表达下调。miRNA 表达与 mRNA 靶标之间存在强相关性(p <0.05)。
本研究成功展示了 mimic miR-155-5p 和 antagonist miR-324-5p 封装壳聚糖的组合的影响,可作为卵巢癌的潜在治疗靶点。
