“…After included normal samples from GTEx database, the expression difference of DIAPH3 was more outstanding. In accordance with our study, several studies have reported DIAPH3 increased in tumor tissues including hepatocellular carcinoma (HCC), osteosarcoma, glioblastoma, and pancreatic cancer [11,12,21,22].…”

Background Cancer is still a serious public health concern across the world at present. Previous studies have suggested that DIAPH3 might play a role in tumorigenesis and progression. However, the prognostic and immunological role of DIAPH3 in human cancers remains unclear. Method The TCGA, GTEx, TIMER2 and GEPIA2 database were utilized to investigate expression difference of DIAPH3 between normal tissues and cancers. For survival analysis, K-M plotter and Pronogscan website were employed. The genetic alteration analysis for DIAPH3 were conducted via cBioPortal database. The DIAPH3 related proteins were screened by the STRING website, and incorporated into KEGG and GO analysis using ‘clusterProfiler' package. Then, we used CIBERSORT algorithm to investigate the percentage of TIICs. For correlation analysis with molecular and immunological subtype, TMB, and MSI, the TISIDB database and SangerBox platform were utilized. To validate the function of DIAPH3 in BLCA, human bladder cancer cells T24 and 5637 were transfection by siRNA and Lipofectamine 8000. The efficiency of knockdown towards target gene was evaluated by qRT-PCR and Western Blot. The CCK-8 assays, clone formation assays, transwell, and wound healing assays were performed to test the proliferation, migration and invasion ability of cells. Results Various type of cancers had increased DIAPH3 expression than normal tissues, and DIAPH3 expression played an adverse prognostic role in most of cancers. Then, function analyses indicated that actin, microtubule and phagocytosis related pathways were enriched in DIAPH3 related proteins. DIAPH3 was strongly correlated to tumor immunity cells infiltration, especially MDSC. In addition, the link between DIAPH3 with immunological subtype, molecular subtype, TMB, and MSI were also observed. Furthermore, the knockdown of DIAPH3 could inhibit the proliferation, migration and invasion of bladder cancer cells. Conclusion In summary, our study demonstrated a correlation between DIAPH3 expression and prognosis, clinicopathological characteristics, immune infiltration cells, and immunotherapy response based on a pan-cancer analysis. The knockdown of DIAPH3 inhibited the proliferation, migration and invasion of bladder cancer cells. These findings might expand our knowledge of DIAPH3 as potential predictive biomarker or therapy target for cancers.

“…Many studies have reported that DIAPH3 was involved in the progression of tumorigenesis such as pancreatic cancer, lung cancer and glioblastoma [33] , [34] , [35] ; moreover, DIAPH3 could be serve as a predictor for response for resistance (rapamycin and taxanes) in glioblastoma [34] ; in addition, DIAPH3 deficiency may lead to the appearance of disorganized cytoskeleton and multipolar spindles (mitotic errors) [36] . Interestingly, cisplatin, as a classical DNA crosslinker, could inhibit DNA duplication, indicating that DIAPH3 knockdown may sensitize cisplatin treatment.…”

“…In this study, we firstly chose DIAPH3 to investigate its role involved in cisplatin resistance, and the function of the rest three genes (AMAMTS15, CARD11 and XDH) would be explored and verified in our further studies. Increasing evidence has shown that DIAPH3 regulates mitotic activities by assembling and separating mitotic spindles [ 34 , 36 ]. Meanwhile, cisplatin, as a classical DNA crosslinker, inhibits DNA duplication, indicating that DIAPH3 knockdown may sensitize cisplatin treatment.…”
