简介：核糖核酸结合基序蛋白8A（RNA—bindingmotifprotein8A，RBM8A）是近年来新发现的一种RNA结合基序蛋白。不少研究报道RBM8A基因蛋白在多种恶性肿瘤中的表达水平明显升高，通过细胞凋亡调控、基因表达、细胞周期调控等多个环节参与恶性肿瘤的发生和发展。本文就RBMSA在恶性肿瘤中的研究进展予以综述。

简介：摘要患儿 男，5月龄，因“生后反复撤机失败、气管切开1个月余”就诊，临床表现有发育迟缓、Robin序列征（腭裂、小下颌、舌后坠）、房间隔缺损、指趾端发育畸形、听力缺失、睡眠呼吸障碍、喂养困难。经医学外显子疾病筛查检测到患儿X染色体编码RBM10基因的（chrX）47044937位点存在c.2263G>A（p.D755N）半合变异，确诊为以马蹄内翻足、房间隔缺损、Robin序列征（小下颌、腭裂、舌后坠）、永存左上腔静脉等畸形的一组综合征，简称为TARP综合征。

简介：目的检测RBM8A在不同结肠癌细胞株中的表达,为进一步体外实验筛选靶细胞。方法采用实时定量反转录聚合酶连锁反应（qRT-PCR）法以及蛋白免疫印迹（Western-blot）法检测RBM8A在结肠癌细胞株SW480、SW620、HT29、LOVO、COLO320DM、T84及人正常结肠上皮细胞株NCM460中的表达。结果RBM8A在7株细胞株中均有表达,其中在结肠癌细胞株SW620和COLO320DM中的表达高于正常细胞株,差异有统计学意义（P〈0.05）,而其余细胞株中RBM8A的表达与正常细胞株差异无统计学意义（P〉0.05）。结论RBM8A在结肠癌细胞株SW620和COLO320DM中高表达,SW620和COLO320DM细胞株或可作为靶细胞。

简介：AbstractImportance:Pathogenic variants in the RBM20 gene are associated with aggressive dilated cardiomyopathy (DCM). Recently, RBM20 was found to be associated with left ventricular non-compaction cardiomyopathy (LVNC). Thus far, only five families with LVNC have been reported to carry variants in RBM20. It remains unknown whether the variants in RBM20 associated with DCM can also cause LVNC.Objective:To elucidate the causative RBM20 variant in two unrelated patients with both LVNC and DCM, and to identify the clinical characteristics associated with variants in RBM20.Methods:Trio whole-exome sequencing (WES) was performed. Variants were filtered and classified in accordance with the guidelines of the American College of Medical Genetics and Genomics (ACMG).Results:We identified two distinct de novo variants in RBM20 (one per patient) in these two patients with LVNC. Both variants have been reported in patients with DCM, without the LVNC phenotype. Patient 1 was an 11-year-old girl who had DCM, LVNC, and heart failure; the ratio of noncompacted-to-compacted myocardium was 2.7:1. A de novo heterozygous variant c.1907G>A (p.Arg636His) in exon 9 was identified in this patient. Patient 2 was a 13-year-old boy who had clinical phenotypes identical to those of Patient 1; the ratio of noncompacted-to-compacted myocardium was 3.2:1 in this patient. WES revealed a de novo heterozygous variant c.1909A>G (p.Ser637Gly) in exon 9. Both variants were previously characterized as pathogenic, and our study classified them as pathogenic variants based on the ACMG guidelines.Interpretation:We found that two patients with LVNC had variants in RBM20. Our results extended the clinical spectrum of the two RBM20 variants and illustrated that the same variant in RBM20 can cause DCM, with or without the LVNC phenotype.
