HOIL-1/RBCK1 deficiency is a new autosomal receiving disorder with dysfunctional cellular responses to pro-inflammatory cytokines, leading to auto-inflammation, pyogenic bacterial disease, and muscle amylopectinosis growth. Our study with integrated bioinformatics studies of the feature genes and the correlative gene functions, investigated the molecular mechanisms of RBCK1 deficiency. GSE31064 dataset expression profile was downloaded from the Omnibus Gene Expression database. Between RBCK1, MYDK88, NEMO deficient fibroblast, and healthy fibroblast specimens, differentially expressed genes (DEGs) were defined. Gene ontology (GO) gene role enrichment analysis and the Kyoto Encyclopedia of Gene and Genome (KEGG) pathway analysis were performed using the Annotation, Visualization and Integrated Discovery Database (DAVID). The protein-protein interaction (PPI) of these DEGs was visualized using Cytoscape. GO analysis revealed that the “Skeletal system development, Extracellular matrix organization, Positive regulation of cell migration, Negative regulation of canonical Wnt signaling pathway, Cell adhesion, Angiogenesis and Negative regulation of BMP signaling pathway, Serine-type carboxypeptidase activity, Polysaccharide binding, Calcium ion binding, frizzled binding, Neuropilin binding, and cell adhesion molecule binding, extracellular exosome, extracellular space, extracellular region, lysosomal lumen, endoplasmic reticulum lumen, cell surface and focal adhesion to BP, MF, and CC, respectively. The study of the KEGG pathway showed that the complement and coagulation cascade, interactions of the ECM receptor, PI3K-Akt signaling pathway, PPAR signaling pathway, TGF-beta signaling pathway, cancer pathway, viral carcinogenesis and focal adhesion pathway were closely correlated with the incidence of RBCK1 deficiency. Importantly, it has been predicted that TK1, AURKB, CDCA2, UBE2C, KIFC1, CEP55, CDCA3, GINS2, MCM6 and CDC45 are significantly associated with RCBK1 deficiency. Our study offers a record of damaged genes and pathways in RCBK1, which will boost the understanding of RBCK1 deficiency pathogenesis and other inherent immunodeficiency diseases. This research has the potential and can possibly use in the clinic for diagnosis and targeted therapy of HOIL-1/RBCK1 disorder and other inherent immunodeficiencies.
Tension is required but not sufficient for focal adhesion maturation without a stress fiber template
