[PMID: 34533670 DOI: 10.1007/s10238-021-00752-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Accepted: 08/09/2021] [Indexed: 02/07/2023]
Abstract
To study the role of HER2/cortactin co-overexpression in advanced gastric cancer (GC). This study retrospectively enrolled 246 patients with stage III GC from January 2015 to December 2016 at our hospital. We explored, using immunostaining techniques, the role of the expression of cortactin and HER2 in the progression of advanced GC. The patient data, including age, sex, cortactin and HER2 expression, pathological parameters and survival, were collected. Univariate and multivariate analyses were used to analyze the characteristics, survival, and prognostic factors of the patients. The results showed that the expression of cortactin was significantly associated with vascular-lymphatic invasion (P < 0.001), N stage (P = 0.001), and TNM stage (P = 0.046). HER2 overexpression correlated with tumor size (P = 0.002), neural invasion (P = 0.002), Lauren classification (P = 0.005) and N stage (P = 0.034). Through univariate analysis using the Kaplan-Meier method, vascular-lymphatic invasion (P = 0.015), neural invasion (P = 0.021), N stage (P < 0.003), and HER2/cortactin co-overexpression (P < 0.028) were shown to be significantly associated with overall survival. Multivariate analysis demonstrated that vascular lymphatic invasion (hazard ratio = 1.481, 95% CI, 1.064 to 2.061, P = 0.020), neural invasion (hazard ratio = 1.505, 95% CI, 1.084 to 2.089, P = 0.015), N stage (N2/N1: hazard ratio = 1.655, 95% CI, 1.048 to 2.641, P < 0.031, N3/N1: hazard ratio = 2.089, 95% CI, 1.325 to 3.295, P < 0.002), and HER2/cortactin co-overexpression (hazard ratio = 1.427, 95% CI, 1.007 to 2.024, P = 0.046) were independent prognostic factors for poor overall survival. The results suggested that HER2/cortactin co-overexpression is an important predictive biomarker for GC patients. GC patients with HER2/cortactin co-overexpression may receive dual-targeted therapy to improve survival prognosis in the future.

Upregulated UCA1 contributes to oxaliplatin resistance of hepatocellular carcinoma through inhibition of miR-138-5p and activation of AKT/mTOR signaling pathway. Pharmacol Res Perspect 2021; 9:e00720. [PMID: 33565716 PMCID: PMC7874507 DOI: 10.1002/prp2.720] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Revised: 12/24/2020] [Accepted: 01/06/2021] [Indexed: 12/17/2022] Open
Abstract
Hepatocellular carcinoma (HCC) inevitably developed oxaliplatin (OXA) resistance after long-term treatment, but the mechanism remains unclear. Here, we found that LncRNA UCA1 was upregulated in most of OXA-resistant HCC tissues and cells (HepG2/OXA and SMMC-7721/OXA). Follow-up analysis and online Kaplan-Meier Plotter revealed that HCC patients with high UCA1 level had a shorter survival compared with those with low expression. Overexpression of UCA1 increased OXA IC50 in HepG2 and SMMC-7721 cells, whereas knockdown of UCA1 decreased OXA IC50 in resistant counterparts. Moreover, dual luciferase reporter assay showed that co-transfection of UCA1-WT plasmid with miR-138-5p mimics enhanced fluorescence signals, whereas co-transfection of UCA1-Mut plasmid and miR-138-5p mimics did not induce any changes. Consistently, UCA1 levels in HepG2/OXA and SMMC-7721/OXA cells were downregulated after transfected with miR-138-5p mimics. UCA1 silencing or transfection of miR-138-5p mmics inhibited the activation of AKT and mTOR in HepG2/OXA and SMMC-7721/OXA cells, whereas UCA1 overexpression increased the phosphorylated AKT and mTOR levels in parental counterparts. Rapamycin or miR-138-5p mimics similarly suppressed the activation of AKT and mTOR, whereas UCA1 overexpression exert opposite roles. Interestingly, administration of rapamycin or miR-138-5p mimics apparently antagonized the effects of UCA1 on AKT and mTOR activation. Besides, depletion of UCA1 triggered more dramatic regression of HepG2 xenografts than that of HepG2/OXA xenografts with OXA treatment and impaired the p-AKT and p-mTOR levels in vivo. In conclusion, our findings provide the evidence that UCA1 may contribute to OXA resistance via miR-138-5p-mediated AK /mTOR activation, suggesting that UCA1 is a potential therapeutic target for HCC.

Prognostic implications of EGFR protein expression in sporadic colorectal tumors: Correlation with copy number status, mRNA levels and miRNA regulation. Sci Rep 2020; 10:4662. [PMID: 32170146 PMCID: PMC7070091 DOI: 10.1038/s41598-020-61688-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2019] [Accepted: 02/26/2020] [Indexed: 11/10/2022] Open
Abstract
Sporadic colorectal cancer (sCRC) is the third most frequent cancer worldwide and the second most common cause of cancer-related deaths (mainly due metastatic dissemination). We investigated the immunohistochemical expression of frequently altered proteins in primary tumors from 51 patients (25 liver metastatic and 26 non-metastatic cases) with a median 103 months follow-up (103 months). We evaluated EGFR copy number (using SNP arrays and FISH) and its expression and regulation (by mRNA and miRNA arrays). We found differences between metastatic and non-metastatic sCRCs for MLH1 (p = 0.05), PMS2 (p = 0.02), CEA (p < 0.001) and EGFR (p < 0.001) expression. EGFR expression was associated with lymph node metastases (p = 0.001), liver metastases at diagnosis (p < 0.001), and advanced stage (p < 0.001). There were associations between EGFR expression-, EGFR gene copy number- and EGFR mRNA levels. We found potential interactions of two miRNAs targeting EGFR expression, (miR-134 and miR-4328, in non-metastatic and metastatic tumors, respectively). EGFR expression was associated with a worse outcome (p = 0.005). Multivariate analysis of prognostic factors for overall survival identified that, the expression of EGFR expression (p = 0.047) and pTNM stage (p < 0.001) predicted an adverse outcome. EGFR expression could be regulated by amplification or polysomies (in metastatic tumors), or miRNAs (miRNA-134, in non-metastatic tumors). EGFR expression in sCRC appears to be related to metastases and poor outcome.

Abstract
Objective: The goal of our current study is to assess the immunohistochemical of p53, p21, nm23, and VEGF expression in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) prognosis after hepatectomy, as well as the prospective molecular mechanisms of prognostic indicator. Methods: There were 419 HBV-related HCC patients who were from southern China of Guangxi province and were used to evaluate the immunohistochemical expression for these biomarkers in prognosis. A genome-wide expression microarray dataset of HBV-related HCC were obtained from GSE14520. Results: In our study, the expression of p53, p21, and nm23 in cancer tissues of patients with hepatitis B-related hepatocellular carcinoma did not affected the clinical outcome of 2 years, 5 years or overall. Patients with high expression of VEGF had a worse overall survival after 2 years of surgery than patients with low expression (adjusted P=0.040, adjusted HR = 1.652, 95% CI = 1.024-2.665). Survival analysis of VEGF in GSE14520 cohort also demonstrated that VEGF mRNA expression also significantly associated with HBV-related HCC OS (adjusted P=0.035, adjusted HR =1.651, 95% CI =1.035-2.634). The prospective molecular mechanisms by co-expression analysis suggested that VEGF might be correlated to regulation of cell proliferation, cell growth and apoptotic process, Rap1 signaling pathway, HIF-1 signaling pathway, PPAR signaling pathway, cell cycle. Whereas the GSEA suggested that VEGF might involve in the regulation of HIF and HIF1A pathway, and TP53 regulation pathway. Conclusion: Our findings suggested that VEGF might be a prognostic indicator of HBV-related HCC, and we also identified the VEGF prospective molecular mechanisms through the whole genome co-expression and GSEA approaches.

Abstract
BACKGROUND Miles procedure is often necessary for patients with low rectal carcinoma. However, this operation often affects the quality of life of patients, to evaluate the advantages of improved operation (anal reconstruction), the quality of life and survival between patients undergoing anal reconstruction and patients undergoing traditional lower abdominal stoma after radical resection were analyzed. METHODS The clinical data of 43 patients with low situated rectal carcinoma were retrospectively analyzed. 23 patients with left lower abdominal stoma after radical resection (Miles procedure) were divided into group A, and 20 patients with reconstruction of the anus in situ after radical resection were in group B. All patients were investigated by the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and QLQ-CR38 questionnaire, the clinical data are recorded. Independent sample T test was used to analyze the difference in quality of life between group A and group B at 3, 6, and 12 months after surgery, and Kaplan-Meier was used to compare the difference in overall survival between group A and group B. RESULTS The results of T test showed that there were statistical significance in global health status and physical functioning between group A and group B at 3 and 6 months, but no statistical significance at 12 months (P = 0.024, P = 0.019, P = 0.115 for global health status; P = 0.004, P = 0.006, P = 0.065 for physical functioning, respectively). Emotional functioning and social functioning were also statistically significant between group A and group B at 3, 6, and 12 months (P = 0.041, P = 0.040, P = 0.034 for Emotional functioning; P = 0.020, P = 0.009, P = 0.032 for social functioning, respectively). This study also found that there was no statistical significance in body image and sexual functioning between group A and group B at 3 months, but there was statistical significance at 6 and 12 months(P = 0.098, P = 0.035, P = 0.045 for body image; P = 0.110, P = 0.048, P = 0.047 for sexual functioning, respectively). There were statistically significant about sexual enjoyment and defecation problems at 3, 6, and 12 months (P = 0.023, P = 0.028, P = 0.050 for sexual enjoyment; P = 0.013, P = 0.011, P = 0.050 for defecation problems, respectively).The results of Kaplan-Meier showed that the overall survival (OS) between group A and group B was not statistically significant (χ2 = 0.600, P = 0.439). CONCLUSIONS There was no difference in survival time between group A and group B, but compared with the patients with left lower abdominal stoma(group A), the quality of life was better in patients with reconstruction of the anus in situ (group B). It is significant to improve the traditional lower abdominal stoma operation.

Abstract
Background: One of our previous studies have demonstrated that the cancer suppressor miR-150 regulated the progression of colorectal cancer (CRC) by down-regulating v-myb avian myeloblastosis viral oncogene homolog (c-Myb). The purpose of present study was to evaluate the prognostic value of the expression of c-Myb and its effector, prostaglandin-endoperoxide synthase 2 (COX-2) in patients with CRC. Methods: We used tissue microarrays (containing 202 CRC tissues and matched adjacent normal tissues) and conducted immunohistochemical analysis and western blotting analysis (containing 3 CRC tissues and matched adjacent normal tissues) to detect the expression of c-Myb and COX-2. Results: Compared with the adjacent nontumorous tissues, both the expression levels of c-Myb and COX-2 were higher in the cancer tissues. A statistically significant correlation was found between the expression of c-Myb and COX-2. Elevated c-Myb and COX-2 were associated with more advanced tumor invasion and poorer overall survival by univariate analysis. Higher expression levels of both c-Myb and COX-2 were significantly associated with shorter overall survival for stage II and stage III patients with 5-Fu based chemotherapy. Multivariate analysis identified the lymph node involvement, distant metastatic spread and the elevated c-Myb and COX-2 as independent factors of poor prognosis for CRC. Conclusions: In conclusion, the overexpression of both c-Myb and COX-2 would be of prognostic screening value in patients with CRC.

Abstract
The present study investigated the expression of non-metastasis 23 (nm 23) in laryngeal cancer tissues and analyzed its correlation with the prognoses of laryngeal cancer patients. A total of 122 laryngeal cancer patients who were admitted to The Affiliated Hospital of Jining Medical College from June 2009 to June 2012, and 30 normal laryngeal mucosal tissues were selected as the control group. Immunohistochemical staining method was used to test the expression of nm 23 in tissues. Quantitative-polymerase chain reaction (q-PCR) and western blotting were conducted to test the expression of nm 23 in tissues at the gene and protein levels, respectively. Moreover, the prognoses of patients were analyzed. The positive expression rate (90.00%) of nm 23 in the normal laryngeal mucosal tissues was markedly higher than that in laryngeal cancer tissues (56.56%) (p<0.05). The expression of nm 23 proteins was correlated with the clinical staging of laryngeal cancer and the metastasis of lymph nodes (p<0.05). The expression of both nm 23 genes and proteins in the laryngeal cancer tissues were significantly lower than those in the normal laryngeal mucosal tissues (p<0.05). The survival rate of the positive nm 23 expression was substantially higher than that of the negative expression with a statistically significant difference (p<0.01). In conclusion, the expression of nm 23 proteins plays an important role in the development and metastasis of laryngeal cancer and may be taken as one of the indicators to evaluate the prognoses of such patients.

Abstract
Peripheral T cell and natural killer cell lymphomas (PT/NKCLs) are rare malignant tumors of lymphoid tissue. The incidence varies by geographical region and race. We reclassified 313 cases of PT/NKCLs based on the 4th edition of the World Health Organization (WHO) classification to demonstrate the distribution of each histologic type of PT/NKCLs in Chinese populations. In our series, extranodal NK/T-cell lymphoma (ENKT) was the most common (37.1%) type, followed by peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) (31.3%) and angioimmunoblastic T-cell lymphoma (AITL) (12.8%). Also, we investigated the expression level of nm23, VEGF, TOP2A, and MUM-1 in all 313 cases. The positive rate of nm23, VEGF, TOP2A, and MUM-1 expression was more than 50% in most histologic types. Among the five common types, the expression rate of nm23 (34.5%) and TOP2A (27.6%) in ENKT were the lowest (P<0.05). VEGF expression was also lowest in ENKT (26.7%), but it was much higher in PTCL-NOS (54.1%), AITL (70.0%), and ALCL-ALK- (56.5%) and ALCL-ALK+ (42.9%). The difference of VEGF expression between ENKT and PTCL-NOS and AITL was significant (P<0.05). Fourteen of 23 (60.9%) cases of ALCL-ALK- and 9 of 14 (64.3%) cases of ALCL-ALK+ were positive for MUM-1, which was much higher than in ENKT (19.8%), PTCL-NOS (26.5%) and AITL (35.0%) (P<0.05). Although the significance of their expression in PT/NKCLs is not clear, we suggested that they may be novel tumor markers for developing targeted therapy in the future.

J Ovarian Res 2018; 11:16. [PMID: 29482638 PMCID: PMC5828062 DOI: 10.1186/s13048-018-0388-x] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2017] [Accepted: 02/06/2018] [Indexed: 12/17/2022] Open
Abstract
Background Ovarian cancer is a leading cause of the death from gynecologic malignancies. Hypoxia is closely related to the malignant growth of cells. However, the molecular mechanism of hypoxia-regulated ovarian cancer cells remains unclear. Thus, this study was conducted to identify the key genes and pathways implicated in the regulation of hypoxia by bioinformatics analysis. Methods Using the datasets of GSE53012 downloaded from the Gene Expression Omnibus (GEO), the differentially expressed genes (DEGs) were screened by comparing the RNA expression from cycling hypoxia group, chronic hypoxia group, and control group. Subsequently, cluster analysis was performed followed by the construction of the protein-protein interaction (PPI) network of the overlapping DEGs between the cycling hypoxia and chronic hypoxia using ClusterONE. In addition, gene ontology (GO) functional and pathway enrichment analyses of the DEGs in the most remarkable module were performed using Database for Annotation, Visualization and Integrated Discovery (DAVID) software. Ultimately, the signaling pathways associated with hypoxia were verified by RT-PCR, WB, and MTT assays. Results A total of 931 overlapping DEGs were identified. Nine hub genes and seven node genes were screened by analyzing the PPI and pathway integration networks, including ESR1, MMP2, ErbB2, MYC, VIM, CYBB, EDN1, SERPINE1, and PDK. Additionally, 11 key pathways closely associated with hypoxia were identified, including focal adhesion, ErbB signaling, and proteoglycans in cancer, among which the ErbB signaling pathway was verified by RT-PCR, WB, and MTT assays. Furthermore, functional enrichment analysis revealed that these genes were mainly involved in the proliferation of ovarian cancer cells, such as regulation of cell proliferation, cell adhesion, positive regulation of cell migration, focal adhesion, and extracellular matrix binding. Conclusion The results show that hypoxia can promote the proliferation of ovarian cancer cells by affecting the invasion and adhesion functions through the dysregulation of ErbB signaling, which may be governed by the HIF-1α-TGFA-EGFR-ErbB2-MYC axis. These findings will contribute to the identification of new targets for the diagnosis and treatment of ovarian cancer.

Liu Q, Xu B, Zhou W. Correlation between chemotherapy resistance in osteosarcoma patients and PAK5 and Ezrin gene expression. Oncol Lett 2017; 15:879-884. [PMID: 29391894 PMCID: PMC5769406 DOI: 10.3892/ol.2017.7355] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2017] [Accepted: 10/24/2017] [Indexed: 12/31/2022] Open
Abstract
The correlation between PAK5 (P21-activated kinase 5) and Ezrin gene expression and chemotherapy resistance of osteosarcoma patients was investigated. The cisplatin (CDDP)-resistance model of osteosarcoma cells SOSP-9607/CDDP was established to detect the cell growth curve. Methyl thiazolyl tetrazolium (MTT) assay was used to detect the drug resistance of cells to chemotherapy drugs. Transwell assay was used to detect the invasive capacity of cells. Semi-quantitative PCR (qPCR) was used to detect the mRNA expression levels in the drug resistance-related genes PAK5 and Ezrin. Western blot analysis was used to detect the protein expression levels in PAK5 and Ezrin. Tumor tissues were taken from the osteosarcoma patients with chemotherapy resistance to detect the expression levels of PAK5 and Ezrin via immunohistochemical detection, and the correlation between PAK5 and Ezrin expressions was studied. The results of MTT assay showed that the growth rate of SOSP-9607 was similar to that of SOSP-9607/CDDP, and the difference was not statistically significant (P>0.05). The sensitivity of SOSP-9607 to CDDP was significantly higher than that of SOSP-9607/CDDP, and the difference was statistically significant (P<0.01). Transwell assay showed that the migration capacity of SOSP-9607/CDDP was significantly better than that of SOSP-9607 (P<0.01), indicating that the drug resistance cell lines of osteosarcoma were constructed successfully. Semi-qPCR and western blot analysis showed that the protein expression levels in PAK5 and Ezrin in SOSP-9607/CDDP were significantly higher than those in SOSP-9607 (P<0.01). The results of immunohistochemistry showed that the expression quantities of PAK5 and Ezrin in osteosarcoma tissues were significantly higher than those in para-tumor tissues (P<0.01). Pearson's correlation analysis showed that expression of PAK5 and Ezrin was positively correlated (r=0.197, P=0.023). The osteosarcoma resistance is closely related to the expression levels of PAK5 and Ezrin genes. Thus, PAK5 and Ezrin genes may affect the tolerance of osteosarcoma patients to chemotherapy drugs during treatment via the synergistic effect.
