Abstract

Non-small cell lung cancer (NSCLC) is one of the most prevalent cancers in the world, and early diagnosis can effectively improve patient survival. Here, differentially expressed circIARS genes are screened from the sequencing results, and their molecular characteristics are examined by Sanger sequencing, RNase R assay, agarose gel electrophoresis (AGE), and fluorescence in situ hybridization (FISH). Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) is performed to detect the expression level of circIARS. The diagnostic value of the signature is analyzed using a subject operating characteristic (ROC) curve. Moreover, plasma is collected from postsurgical, chemotherapy, and relapse patients to investigate the prognostic value of circIARS in NSCLC. The expression of circIARS is greater in both the plasma and tissues of NSCLC patients than in those of healthy individuals, and could be used to distinguish NSCLC patients from patients with benign pulmonary disease (BPD), small cell lung cancer (SCLC) patients, and healthy individuals. The expression level of circIARS relatively decreases after antitumor therapy, such as chemotherapy, and relatively increases after recurrence. ROC analysis reveals that circIARS has better detection efficiency than traditional markers. In addition, circIARS expression level is strongly correlated with several clinicopathological parameters. Finally, we tentatively predict the downstream miRNAs or RBP that might bind to circIARS. Plasma circIARS is significantly greater in NSCLC patients and has good stability and specificity as a diagnostic marker, which could aid in the adjuvant diagnosis and dynamic monitoring of NSCLC.

Abstract

TIPE1 is a gene in the TNFAIP8 family involved in immune regulation and tumorigenesis. Although previous studies demonstrated that TIPE1 might play different roles in different tumors, its expression and role in lymphoma are unclear. Here we observed TIPE1 expression in diffuse large B cell lymphoma (DLBCL). Two microarrays containing 96 tumor tissue specimens were obtained from the Affiliated Hospital of Nantong University biobank. All specimens came from patients with a clear pathological diagnosis of lymphoma, lymphadenitis, breast cancer, or bladder cancer, and we performed immunohistochemical experiments on these tissue specimens. GEPIA and TIMER platforms were used for bioinformatic analyses. We found higher TIPE1 expression in tumor tissues from patients with lymphoma compared with those with lymphadenitis, breast cancer, or bladder cancer. The GEPIA and TIMER analyses revealed that TIPE1 was upregulated in DLBCL tissues but not in invasive breast carcinoma, urothelial bladder carcinoma, or liver hepatocellular carcinoma tissues. TIPE1 expression was irrelevant for pathological stage, overall survival, or DLBCL immune infiltration levels. However, TIPE1 expression was correlated with MKI67 expression in DLBCL. Overall, TIPE1’s high expression levels in DLBCL may contribute to tumor growth in DLBCL.
