    • The present invention provides methods of determining a putative agent that inhibits tumorigenesis in retinoblastoma protein deficient cells, the methods comprising determining whether the putative agent decreases phosphorylation of threonine residue 187 of p27, decreases S-phase kinase-associated protein 2 interaction with p27 having a phosphorylated threonine residue 187, or an increase in apoptosis of retinoblastoma protein deficient cells. The present invention also provides the agent, the pharmaceutical composition, and methods of inhibiting, preventing and treating tumorigenesis in retinoblastoma deficient cells, the method comprising administration of the agent that decreases phosphorylation of threonine residue 187 of p27 or the S-phase kinase-associated protein 2 interaction with p27 having a phosphorylated threonine residue 187.
    • 本发明提供了确定抑制视网膜母细胞瘤蛋白质缺陷细胞中的肿瘤发生的推定剂的方法,所述方法包括确定推定剂是否降低p27的苏氨酸残基187的磷酸化,降低与p27的S期激酶相关蛋白2相互作用 磷酸化苏氨酸残基187,或视网膜母细胞瘤蛋白缺陷细胞凋亡的增加。 本发明还提供了抑制,预防和治疗视网膜母细胞瘤缺陷细胞中的肿瘤发生的药剂,药物组合物和方法,所述方法包括施用降低p27苏氨酸残基187的磷酸化或S期激酶相关 蛋白质2与具有磷酸化苏氨酸残基的p27的相互作用。

    • A microfluidic filtration unit for trapping particles of a predetermined nominal size present in a fluid is provided. The unit comprises a fluid chamber connected to an inlet for introducing the fluid to be filtered and an outlet for discharging filtered fluid, a filtration barrier arranged within the fluid chamber, said filtration barrier comprising a plurality of pillars arranged substantially perpendicular to the path of fluid flow when fluid is introduced into the fluid chamber, said pillars being aligned to form at least one row extending across said path of fluid flow, wherein each of said at least one row of pillars in the filtration barrier comprises at least one fine filtration section comprising a group of pillars that are spaced apart to prevent particles to be filtered from the fluid from moving between adjacent pillars, and at least one coarse filtration section comprising a group of pillars that are spaced apart to permit the movement of particles between adjacent pillars.
    • 提供了用于捕获存在于流体中的预定公称尺寸的微粒的微流体过滤单元。 该单元包括连接到入口的流体室,用于引入要过滤的流体和用于排出过滤流体的出口,布置在流体室内的过滤阻挡层,所述过滤屏障包括基本上垂直于流体路径布置的多个柱 当流体被引入到流体室中时,所述柱被对准以形成跨越所述流体流动路径延伸的至少一排,其中所述过滤阻挡层中的所述至少一排柱中的每一个包括至少一个精细过滤部分,其包括 间隔开的一组支柱,以防止颗粒从流体中过滤,以在相邻的柱之间移动;以及至少一个粗过滤部分,其包括间隔开的一组支柱,以允许颗粒在相邻支柱之间移动。
