  • Expression and clinical significance of HIST1H1B gene in bladder cancer

    ObjectiveTo investigate the expression and clinical significance of HIST1H1B gene in bladder cancer.MethodsInformation on HIST1H1B in the dataset GSE13507 was downloaded from the GEO database. Discrepancy in expression of HIST1H1B in normal tissues and bladder cancer tissues was analyzed by t-test. Survival analysis was performed by using Log-rank algorithm. The association between HIST1H1B gene expression and clinicpathological features was analyzed using Chi-square test. Gene enrichment analysis (GSEA) was performed to explore possible pathways of HIST1H1B involved in bladder cancer.ResultsHIST1H1B was down-regulated in normal tissues and highly expressed in bladder cancer tissues (P=0.002 5). The expression of HIST1H1B was associated with age, gender, T stage, M stage, N stage, disease stage, but not associated with invasiveness and progression. Whether in overall survival (HR=1.732, 95%CI 1.070 to 2.803) or tumor-specific survival (HR=2.000, 95%CI 0.996 to 4.017), patients with high expression of HIST1H1B were significantly lower than that in patients with low expression (P<0.05). GSEA results showed that HIST1H1B may influence the occurrence and development of bladder cancer by regulating MYC signaling pathway V2, G2M checkpoint, E2F signaling pathway, spermatogenesis, mitotic spindle, etc.ConclusionsHIST1H1B may be a biomarker for determining the prognosis of bladder cancer and a target for treatment of bladder cancer.
