主要方法:

在ADPKD患者衍生的囊细胞中分析表观基因调节者的基因表达.
使用小分子药物 (AZD-5153和PTC-209) 抑制Brd4和BMi1.
在ADPKD细胞,3D囊模型和小鼠Pkd1无细胞中体外药物疗效的评估,包括通过KMs输送药物.

主要成果:

发现Brd4和BMi1在ADPKD患者细胞中被上调.
用AZD-5153和PTC-209抑制Brd4和BMi1显著减缓了ADPKD细胞增殖.
在KM中联合药物治疗在ADPKD模型中显示了减少扩散的协同效应.

结论:

Brd4和BMi1代表了ADPKD的新型治疗点.
用脏向纳米药物向表观基因组,为ADPKD治疗提供了一个有前途的新策略.
这种方法显示了在ADPKD中改善药物输送和协同治疗效果的潜力.

Targeted Cancer Therapies

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.
There are several types of targeted therapies against...

Nephrons

Nephrons

The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...
