Diffuse large B cell lymphoma(DLBCL)is one of the most prevalent lymphoid *** current standard of care can cure about two-thirds of DLBCL patients.1 Primary testicular diffuse large B-cell lymphoma(PT-DLBCL)is a rare but highly aggressive form of mature B-cell lymphoma that accounts for approximately 1%-9%of testicular *** from nodal DLBCL,PT-DLBCL has a markedly worse prognosis because of inferior response to the current treatment regimens and significant extranodal tropism.2 Three main questions remained unresolved in the field of PT-DLBCL research.

目的·分析线粒体相关基因SFXN3(sideroflexin 3)在头颈部鳞状细胞癌(head and neck squamous cell carcinoma,HNSCC)中的表达及其对细胞增殖的影响。方法·从公共数据库获取与线粒体相关的基因和TCGA-HNSCC数据集,使用生物信息学方法筛选出目标基因SFXN3。使用UALCAN数据库分析SFXN3在HNSCC患者样本中的表达,并根据TCGAHNSCC队列和GEO队列(GSE65858、GSE41613和GSE27020)对不同SFXN3表达水平的患者进行生存分析,使用TCGA-HNSCC队列和GEO队列(GSE40020、GSE210287)在治疗有应答和无应答的患者之间比较SFXN3表达水平差异。通过实时荧光定量PCR(quantitative real-time PCR,qRT-PCR)在收集的HNSCC癌和癌旁组织验证SFXN3的表达情况,并检测SFXN3在人正常口腔上皮细胞和HNSCC肿瘤细胞系中的表达水平。构建稳定敲低SFXN3的HNSCC细胞株,使用Incucyte活细胞成像分析系统和平板克隆形成实验观察SFXN3对HNSCC细胞增殖能力的影响。将稳定敲低SFXN3的细胞和对照组细胞的总RNA进行转录组测序,对敲低组相比对照组差异表达下调的基因进行通路富集分析。结果·SFXN3在HNSCC患者肿瘤组织中高表达(P=0.000),SFXN3高表达组患者预后较差(均P<0.05);治疗无应答者SFXN3表达水平高于有应答者(P=0.008),提示不良预后。并且在收集的HNSCC肿瘤组织和HNSCC细胞系上验证了SFXN3的高表达(均P<0.05)。SFXN3的表达水平敲低后,HNSCC细胞的增殖能力下降,平板克隆形成数目减少(均P<0.05)。RNA测序显示,SFXN3敲低组的HNSCC细胞差异表达下调的基因在DNA复制、细胞周期、线粒体翻译、线粒体RNA代谢过程、线粒体基因表达等通路富集。结论·SFXN3在HNSCC中高表达,与患者预后负相关。HNSCC细胞敲低SFXN3后增殖能力和平板克隆形成能力受到抑制,可能通过影响线粒体功能发挥作用。

Deubiquitinases(DUBs)are a class of enzymes that are able to reverse the process of ubiquitination.1 Extensive research has revealed that there are more than 100 DUBs found in humans,which are classified into seven main families:ubiquitin-specific proteases(USPs),ubiquitin carboxyl-terminal hydrolases,the Machado-Joseph disease domain superfamily,the otubain/ovarian tumor-domain containing proteins,the ZUFSP(Zinc finger with UFM1-specific peptidase domain protein)family,the JAB1/MPN/MOV34 proteases,and the novel motif interacting with ubiquitin-containing DUB *** DUBs are cysteine proteases,except the JAB1/MPN/MOV34 proteases,which are Zn^(2+) metalloproteases.
