基于表型的小分子筛选是鉴定细胞功能调节剂的有力方法。然而,这样的筛选通常使用不一定模拟复杂生理状况或疾病状态的条件在体外进行。在这里,我们使用分子细胞条形码来实现小分子文库的直接体内表型筛选。这种方法的多重性质允许快速体内分析数百至数千种化合物。使用该平台,我们筛选了>700种针对水解酶的共价抑制剂对胰腺癌转移播种的影响。我们鉴定了多个命中,并确认一种化合物的相关靶标为脂肪酶ABHD 6。药理学和遗传学研究证实了这种酶作为转移适应性调节剂的作用。我们的研究结果突出了这种多重筛选平台在体内研究复杂过程的适用性。
Phenotype-based small molecule screening is a powerful method to identify regulators of cellular function. However, such screens are generally performed in vitro using conditions that do not necessarily model complex physiological conditions or disease states. Here, we use molecular cell barcoding to enable direct in vivo phenotypic screening of libraries of small molecules. The multiplexed nature of this approach allows rapid in vivo analysis of hundreds to thousands of compounds. Using this platform, we screened >700 covalent inhibitors directed towards hydrolases for their effect on pancreatic cancer metastatic seeding. We identified multiple hits and confirmed the relevant target of one compound as the lipase ABHD6. Pharmacological and genetic studies confirmed the role of this enzyme as a regulator of metastatic fitness. Our results highlight the applicability of this multiplexed screening platform for investigating complex processes in vivo.
