The distribution of screened phages in tumors and normal tissues was detected by using immunohistochemistry. The affinity of monoclonal phage to Bcap-37 cells was identified by using enzyme linked immunosorbent assay (ELISA).

The inhibitory effect of miR-106b inhibitory sequence on the expression of miR-106b was verified by using reverse transcription quantitative polymerase chain reaction (qRT-PCR). Whether phosphatase and tensin homolog (PTEN) was the target gene of miR-106b was analyzed by using bioinformatics and luciferase report vector. PTEN small interfering RNA (siRNA) was used to inhibit the expression of PTEN in Hep-2 and TU212 cells. Transwell method and Western blot were used to detect the change of invasion ability of Hep-2 and TU212 cells after miR-106b silencing or the PTEN intervening, and the expression change of PTEN, epithelial cadherin and vimentin. \u0000 \u0000 \u0000Results \u0000The relative expression levels of miR-106b in Hep-2 and TU212 cells in the experimental group were 0.110 ± 0.037 and 0.074 ± 0.009, respectively, which were lower than those in the negative control group (1.013±0.059 and 1.035±0.062, respectively; all P < 0.05).

The bioinformatics analysis results showed that 3'-UTR region of PTEN mRNA was complementary to 3'-UTR region of miR-106b. Dual-luciferase reporter system analysis showed that the luciferase reporter activity of wild-type PTEN gene transfected with miR-106b was decreased to (22.84±2.68)%, and that of mutant PTEN gene transfected with miR-106b was almost unchanged [(92.08±3.44)%], and the difference was statistically significant (P < 0.001). The expression level of PTEN protein of Hep-2 and TU212 cells in the experimental group was higher than that in the negative control group. Transwell method showed that the number of invasive cells in each field of Hep-2 and TU212 cells in the experimental group with the inhibition of PTEN expression was more than that in the experimental group without the inhibition of PTEN expression [(65.08±3.57) vs. (26.72±2.58), (57.38±4.96) vs. (31.81±2.97), all P < 0.05].

The positive expression rate of hMTERF3 in the good prognosis group was 57.4% (35/61), which was significantly lower than that in the poor prognosis group (81.5%, 22/27) (χ 2= 4.766, P= 0.029). The positive expression rate of Foxp3 in the good prognosis group was 55.7% (34/61), which was significantly lower than that in the poor prognosis group (85.2%, 23/27) (χ 2= 7.113, P= 0.008). The proportions of patients with medium and high differentiation or stage Ⅰ- Ⅱ in the good prognosis group were 82.0% (50/61) and 68.8% (42/61), respectively, which were significantly higher than those in the poor prognosis group [48.15% (13/27) and 25.93% (7/27)] (both P < 0.05). Logistic regression analysis showed that the poor differentiation, stage Ⅲ-Ⅳ, hMTERF3-positive and Foxp3-positive were the risk factors for poor prognosis in NSCLC patients (all P < 0.05). \u0000 \u0000 \u0000Conclusions \u0000The positive expression rates of hMTERF3 and Foxp3 in patients with good prognosis are lower. The hMTERF3-positive and Foxp3-positive are risk factors for poor prognosis in NSCLC patients. \u0000 \u0000 \u0000Key words: \u0000Carcinoma, non-small-cell lung; Mitochondrial proteins; Forkhead transcription factors; Human mitochondrial transcription termination factor 3; Forkhead box protein 3; Prognosis","PeriodicalId":9505,"journal":{"name":"肿瘤研究与临床","volume":"32 1","pages":"6-10"},"PeriodicalIF":0.0,"publicationDate":"2020-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47027088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
