Cell－Systems：构建RNA结合蛋白的剪接调控作用预测模型
基因组研究结果显示，人体内超过90%的基因存在选择性剪接(alternative splicing)。该过程在不同组织以及不同生理阶段受到严格的调控，其失调会导致多种疾病的发生。选择性剪接的体内调控主要由前体mRNA中的顺式元件(cis-elements) 招募反式剪接作用因子（trans-a

人胚肾 293 (HEK293) 细胞在重组蛋白表达中是最常见的宿主细胞。 这类细胞能够表达大量的膜蛋白，如 G 蛋白偶联受体 (GPCR) ，是无法在最常见的生物制药生产宿主，如：中国仓鼠卵巢 (CHO) 细胞中作表达。 HEK293 虽然是蛋白表达的极好宿主，然而 HEK293 细胞

PCRfree的靶向捕获技术遇上PCRfree－PacBio－SMRT测序
高通量测序技术已经被广泛用于疾病基因组特征和分子机制研究，研究策略无非是全基因组测序或是靶向测序，在靶向测序中，常见的靶向富集技术有PCR扩增目的区域或基于探针的靶向捕获技术，但这两种方法都很难绕过一个关键步骤－PCR扩增，使得研究人员无法对原始的基因组区域进行测序，从而无法保证测序结果的真实性
