Expression and clinical significance of CCDC8 and TGF-β1 in non-small cell lung cancer / 实用肿瘤学杂志

Objective The aim of this study was to investigate the expression of CCDC8(coiled-coil domain containing 8, P90)and transforming growth factor β 1(TGF- β1)in none small cell lung cancer(NSCLC),and its relationship with clinicopatho-logical characteristics. Methods The expression of CCDC8 and TGF-β1 in NSCLC was analyzed in the TCGA database. The Kap-lan-Meier curve was plotted to analyze its correlation with survival of patient. The expression of CCDC8 and TGF-β1 in 204 cases of conventional paraffin-embedded NSCLC was detected by immunohistochemical staining and their relationship with clinicopatholog-ical features of NSCLC was analyzed. The relationship between the expression of CCDC8 and TGF-β1 and the overall survival(OS) of patients was analyzed by Cox regression. Results The expression of CCDC8 in NSCLC patients was positively correlated with TGF-β1 expression in the TCGA data(P<0. 05). OS was low in patients with the low expression of CCDC8(HR=1. 32,P=0. 0437). In 204 NSCLC tissues,CCDC8 expression was positively correlated with TGF-β1 expression(P=0. 023). Cox univariate analysis of CCDC8 expression in NSCLC was associated with OS(P=0. 013);whereas the expression of CCDC8 and TGF-β1 was not associat-ed with survival in patients with NSCLC(P=0. 967,P=0. 816). Cox multivariate analyses of TNM staging and CCDC8 were progno-sis factors in patients with NSCLC(P=0. 016). Conclusion The expression of CCDC8 is correlated the expression of TGF-β1 in NSCLC. CCDC8 may be a prognostic factor for patients with NSCLC.

Research progress of the relationship between 14-3-3ζ and malignant tumor / 实用肿瘤学杂志

The 14-3-3 protein is a highly conserved acidic polypeptide family involved in intracellular signaling,protein transportation, cell proliferation, invasion, migration, and apoptosis. Many studies have shown that 14-3-3ζhas a high expression level in many malignant tumors. This paper introduces the structure of 14-3-3ζ,the biological function,and the development of the malignant tumor ( breast cancer,lung cancer,hepatocel-lular carcinoma,glioma,head and neck neoplasms) related to the development of 14-3-3ζand treatment of ma-lignant tumor in order to provide valuable information and ideas.

Treatment progress of chemotherapy induced thrombocytopenia / 实用肿瘤学杂志

Chemotherapy induced thrombocytopenia( CIT) is a major dose-limiting hematologic toxicity with cancer patients.Aside from bleeding risk, thrombocytopenia limits chemotherapy doses and frequencies. While platelet transfusion is remain the elementary method for CIT,administration of platelet growth factors,such as recombinant human interleukin-11(rhIL-11),recombinant human thrombopoietin(rhTPO)and thrombopoie-tin receptor agonist(TPO-RA),are convenient and effective platelet-support strategies for patients receiving myelosuppressive chemotherapy.In addition,other cytokines and proximal splenic artery embolization( PSAE) are expected to be new clinical therapies.In this review,we summarize the existing data and approaches in the treat-ment progress of CIT.

Research on the expression of Caveolin-1 with EGFR mutations in non-small cell lung cancer tissues and its clinical significance / 实用肿瘤学杂志

Objective This study aims to examine expression of Caveolin -1 in non smoking cell lung cancer(NSCLC)and to discusses the relationship between expression of Caveolin -1 and the Epidermal growth factor receptor mutations .Methods Immunohistochemical staining was used to determine the Caveolin -1 ex-pression and ARMS-qPCR was used to measure EGFR mutations in 40 cases of lung cancer tissue .The clinical pathological characteristics and correlations in patients were analyzed .Results The expression of Caveolin -1 in human lung cancer was significantly lower than that in normal lung tissue ,and negatively correlated with EGFR mutations ,which was statistically significant .Conclusion Caveolin -1 expression is negatively correlated with EGFR mutations in non-small cell lung cancer and related to the histologic type .Caveolin-1 may be a molecu-lar target for diagnosis and judgment of NSCLC .
