Wei HF, Zhang RF, Zhao YC, Tong XS. SERPINB7 as a prognostic biomarker in cervical cancer: Association with immune infiltration and facilitation of the malignant phenotype. Heliyon 2023; 9:e20184. [PMID: 37809412 PMCID: PMC10559959 DOI: 10.1016/j.heliyon.2023.e20184] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Revised: 09/06/2023] [Accepted: 09/13/2023] [Indexed: 10/10/2023] Open
Abstract
Purpose The purpose of this study was to investigate the expression patterns, predictive significance, and roles in the immune microenvironment of Serpin Family-B Member 7 (SERPINB7) in cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC). Methods The expression of SERPINB7 and its prognostic relevance were evaluated using RNA-seq data from The Cancer Genome Atlas. SERPINB7 regulation of CESC cell growth and metastasis was investigated using MTT, scratch, and Transwell assays. In vivo effects of SERPINB7 were examined in xenograft model mice and differentially expressed genes (DEGs) associated with SERPINB7 were identified to explore its functional role in oncogenesis. Associations between SERPINB7 levels, chemosensitivity, and immune infiltration were assessed, and mutations and methylation of SERPINB7 were evaluated using the cBioPortal and MethSurv databases, respectively. Results SERPINB7 was up-regulated in CESC samples as well as in other tumors, and patients with higher SERPINB7A mRNA levels exhibited shorter overall survival. The area under the curve for the use of SERPINB7 in CESC diagnosis was above 0.9, and the gene was shown to regulate tumor cell proliferation and metastasis in vitro and in vivo. Overall, 398 DEGs enriched in key CESC progression-related signaling pathways were identified. SERPINB7 expression was additionally correlated with intratumoral immune infiltration and immune checkpoint activity. Patients expressing higher SERPINB7 levels exhibited distinct chemosensitivity profiles, and methylation of the SERPINB7 gene was linked to CESC patient prognostic outcomes. Conclusion SERPINB7 was found to be a crucial regulator of CESC progression, prognosis, and the tumor immune microenvironment, highlighting its potential as a diagnostic and prognostic biomarker and target for CESC immunotherapy.

Abstract
Pancreatic carcinoma is usually diagnosed late when treatment options are limited and is considered a chemo-resistant malignancy. However, early stage, good performance status and specific patient subgroup are thought to have a more favorable prognosis. Search for novel molecular biomarkers, which could predict treatment resistance, represents a major opportunity, but also a challenge in further research. This review summarizes most aspects of individualized therapy of pancreatic cancer including promising biomarkers, BRCA-deficient pancreatic cancer and its etiology. It may be estimated that nearly a third of metastatic pancreatic ductal adenocarcinoma patients could benefit from treatment other than gold standard chemotherapy. Thus, other aspects of an individualized approach concerning the main factors for the choice of the best therapy for individual pancreatic cancer patient (surgery and chemotherapy), as well as the future directions (target therapy and immunotherapy), are also addressed.

SERPINB7 Expression Predicts Poor Pancreatic Cancer Survival Upon Gemcitabine Treatment. Transl Oncol 2018; 12:15-23. [PMID: 30245304 PMCID: PMC6149193 DOI: 10.1016/j.tranon.2018.08.019] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2018] [Revised: 08/23/2018] [Accepted: 08/29/2018] [Indexed: 02/07/2023] Open
Abstract
Stratification of patients with pancreatic ductal adenocarcinoma (PDAC) remains a key challenge in the field of clinical oncology. No predictive biomarkers have yet been found for any available treatment options. Previously, we identified SERPINB7 as a putative biomarker for PDAC and thus, herein, we aimed to validate our previous findings and assessed the predictive value of SERPINB7. Patients who underwent surgery and received gemcitabine (gem) or gemcitabine plus nab-paclitaxel (gem/nab) as adjuvant therapy, between 2011 and 2017, were included in this study (n = 57). Expression level of SERPINB7 was assessed in tumor tissue by immunohistochemistry (IHC) and RNA in situ hybridization (RNA ISH). Its association with disease-free survival (DFS) and overall survival (OS) was investigated. While IHC did not show any correlation between survival and the protein level of SERPINB7, RNA ISH revealed that expression of SERPINB7 was associated with a poor DFS (P = .01) and OS (P = .002) in the gem group but not in the gem/nab. Adjusted Cox-regression analysis confirmed the independent predictive value of SERPINB7 on OS (P = .006, HR: 3.47; 95% CI: 1.49–8.09) in the gem group. In conclusion, SERPINB7 was identified as the first predictive RNA biomarker for PDAC. This study suggests that patients who expressed SERPINB7 might receive another treatment than gem alone.

Abstract
Emerging evidence has identified that long non-coding RNAs (lncRNAs) may play an important role in the pathogenesis of many cancers, pancreatic cancer (PC) included. However, the role of linc00462 in PC remains unclear. The aim of our present study was to investigate the potential functions of linc00462 in PC and to identify the underlying mechanisms of action. CCK8 assay, transwell assay, cell cycle assay, cell apoptosis assay, EdU assay, western blot assay, cell adhesion assay, HE staining, IF staining, ELISA assay, vivo growth and metastasis assay, and colony formation assay were performed. We demonstrated that OSM mediated up-regulation of linc00462 promoted cell proliferation by accelerating cell cycle process and inhibiting cell apoptosis and adhesion in vitro, enhanced cell migration and invasion by accelerating EMT process, promoted tumor growth and matastasis in vivo and was associated with large tumor size, poor tumor differentiation, TNM stage and distant metastasis in patients of PC. In addition, we demonstrated that linc00462 was a target of miR-665. Linc00462 overexpression enhanced the expression levels of TGFBR1 and TGFBR2, and thus activated the SMAD2/3 pathway in PC cells. In conclusion, linc00462/miR-665/TGFBR1/2 regulatory network may shed light on tumorigenesis in PC.
