补充内容

PSMD4在多种实体肿瘤中上调,包括肝细胞癌(HCC),其存在与细胞增殖、Akt/GSK-3β/环氧化酶2(COX2)途径的激活、抑制p53启动子活性以及p53降解增加等因素有关。PSMD4通过Akt/COX2途径和p53抑制推动肝细胞癌的进展。PSMD4通过蛋白水解途径中的泛素介导和蛋白酶体介导蛋白降解,促进细胞增殖,与肝细胞癌的发展密切相关。 研究发现,PSMD4过度表达在HCC组织和细胞系中确定,通过Northern blot、Western blot和免疫组化技术。沉默PSMD4可阻止细胞增殖和肿瘤生长,诱导细胞凋亡。进一步的研究表明,PSMD4的阻断能够抑制肝细胞癌的发生。

PSMD4基因敲除细胞系的构建通常涉及的步骤

1.选择合适的靶向PSMD4基因的sgRNA序列,通常利用在线工具设计合适的sgRNA序列。 

2.合成设计好的sgRNA序列,通常通过化学合成来制备。 

3.将合成的sgRNA和Cas9蛋白转染入目标细胞内,使其形成编辑复合物。 

4.使用适当的筛选方法(如阳性筛选标记物)筛选出成功编辑的细胞。 

5.对成功编辑的细胞进行单克隆化,并验证PSMD4基因的敲除效果,通常通过PCR、Western blot等方法进行验证。 

6. 对PSMD4敲除细胞系进行功能验证,如观察细胞增殖、凋亡等生物学特征的变化,评估PSMD4基因敲除对细胞功能的影响。

关于基因Official SymbolPSMD4
Previous SymbolPSMD4
Official Full NameProteasome 26S subunit ubiquitin receptor, non-ATPase 4
SynonymsRpn10, S5A, AF, AF-1
Location1q21.3
Gene TypeProtein Coding
Uniprot IDQ5VWC4
Pathway/LibraryRegulation of activated PAK-2p34 by proteasome mediated degradation, Assembly of the pre-replicative complex
Gene SummaryThe 26S proteasome is a multicatalytic proteinase complex with a highly ordered structure composed of 2 complexes, a 20S core and a 19S regulator. The 20S core is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits. The 19S regulator is composed of a base, which contains 6 ATPase subunits and 2 non-ATPase subunits, and a lid, which contains up to 10 non-ATPase subunits. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. An essential function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides. This gene encodes one of the non-ATPase subunits of the 19S regulator lid. Pseudogenes have been identified on chromosomes 10 and 21. [provided by RefSeq, Jul 2008]
