概括
甲基转移酶类10 (METTL10) 在受损的小细胞中被下调,导致慢性病的进展. 恢复METTL10水平可能会保护受体细胞免受损伤和脱差.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 分子生物学分子生物学
- 遗传学 是一个遗传学.
背景情况:
- 慢性病 (CKD) 是一个全球性的健康问题,细胞损伤是质细胞疾病的核心,如焦点细分质硬化症 (FSGS).
- 氨酸甲基化,一个关键的翻译后修饰,涉及甲基转移酶涉及各种疾病,包括脏疾病.
- 甲基转移酶样10 (METTL10) 与估计的淋巴细胞过率 (eGFR) 和CKD风险有关,但其在细胞损伤中的具体作用尚不清楚.
研究的目的:
- 研究甲基转移酶样10 (METTL10) 在细胞损伤中的作用及其对慢性病 (CKD) 的潜在贡献.
- 鉴定受体损伤中差异表达的基因,并验证METTL10在受体健康和疾病中的表达和功能.
主要方法:
- 在细胞损伤中差异表达基因的生物信息分析.
- 招募患有异常性FSGS的患者,并建立Adriamycin (ADR) 诱导的病小鼠模型.
- 评估METTL10表达在人类FSGS,ADR治疗小鼠和ADR刺激的小鼠受体,以及对受体分化标志物的分析.
主要成果:
- 在FSGS患者和ADR治疗小鼠的受损受体细胞中,METTL10显著下调,与尿白蛋白/肌素比率 (UACR) 有负相关.
- 在实验室中,ADR诱导的 podocyte 损伤导致 METTL10 的减少, podocyte 脱差 (失去了 synaptopodin, podocin, nephrin, WT-1),并增加了介质细胞标记物 (牛,desmin, pax2).
- 对METTL10的抑制加剧了小细胞脱差,表明其具有保护作用.
结论:
- 降低METTL10的调节是慢性病 (CKD) 中 podocyte 损伤的一个特征.
- 在破坏性条件下,METTL10在调节受体细胞脱分方面发挥着至关重要的作用.
- METTL10作为受体细胞的保护因子,表明其作为脏疾病治疗点的潜力.

Drugs that Destabilize Microtubules
1.9K
Microtubules are dynamic structures and can be regulated by microtubule targeting agents (MTAs). Microtubule destabilizing drugs are a class of MTAs that destabilize and prevent microtubules' polymerization. Both natural and synthetic chemicals can be found under this class of drugs. Vincristine and vinblastine, two vinca alkaloids, and colchicine were among the first to be discovered. These drugs can affect cells in various ways, either by inducing a change in cell morphology, preventing...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
