Based on machine learning, CDC20 has been identified as a biomarker for postoperative recurrence and progression in stage I & II lung adenocarcinoma patients. Front Oncol 2024; 14:1351393. [PMID: 39114311 PMCID: PMC11303833 DOI: 10.3389/fonc.2024.1351393] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Accepted: 06/28/2024] [Indexed: 08/10/2024] Open
Abstract
Objective By utilizing machine learning, we can identify genes that are associated with recurrence, invasion, and tumor stemness, thus uncovering new therapeutic targets. Methods To begin, we obtained a gene set related to recurrence and invasion from the GEO database, a comprehensive gene expression database. We then employed the Weighted Gene Co-expression Network Analysis (WGCNA) to identify core gene modules and perform functional enrichment analysis on them. Next, we utilized the random forest and random survival forest algorithms to calculate the genes within the key modules, resulting in the identification of three crucial genes. Subsequently, one of these key genes was selected for prognosis analysis and potential drug screening using the Kaplan-Meier tool. Finally, in order to examine the role of CDC20 in lung adenocarcinoma (LUAD), we conducted a variety of in vitro and in vivo experiments, including wound healing assay, colony formation assays, Transwell migration assays, flow cytometric cell cycle analysis, western blotting, and a mouse tumor model experiment. Results First, we collected a total of 279 samples from two datasets, GSE166722 and GSE31210, to identify 91 differentially expressed genes associated with recurrence, invasion, and stemness in lung adenocarcinoma. Functional enrichment analysis revealed that these key gene clusters were primarily involved in microtubule binding, spindle, chromosomal region, organelle fission, and nuclear division. Next, using machine learning, we identified and validated three hub genes (CDC45, CDC20, TPX2), with CDC20 showing the highest correlation with tumor stemness and limited previous research. Furthermore, we found a close association between CDC20 and clinical pathological features, poor overall survival (OS), progression-free interval (PFI), progression-free survival (PFS), and adverse prognosis in lung adenocarcinoma patients. Lastly, our functional research demonstrated that knocking down CDC20 could inhibit cancer cell migration, invasion, proliferation, cell cycle progression, and tumor growth possibly through the MAPK signaling pathway. Conclusion CDC20 has emerged as a novel biomarker for monitoring treatment response, recurrence, and disease progression in patients with lung adenocarcinoma. Due to its significance, further research studying CDC20 as a potential therapeutic target is warranted. Investigating the role of CDC20 could lead to valuable insights for developing new treatments and improving patient outcomes.

Abstract
Treatment of lung cancer with conventional therapies, which include radiation, surgery, and chemotherapy results in multiple undesirable adverse or side effects. The major clinical challenge in developing new drug therapies for lung cancer is resistance, which involves mutations and disturbance in various signaling pathways. Molecular abnormalities related to epidermal growth factor receptor (EGFR), v-Raf murine sarcoma viral oncogene homolog B1 (B-RAF) Kirsten rat sarcoma virus (KRAS) mutations, translocation of the anaplastic lymphoma kinase (ALK) gene, mesenchymal-epithelial transition factor (MET) amplification have been studied to overcome the resistance and to develop new therapies for non-small cell lung cancer (NSCLC). But, inevitable development of resistance presents limits the clinical benefits of various new drugs. Here, we review current progress in the development of molecularly targeted therapies, concerning six clinical biomarkers: EGFR, ALK, MET, ROS-1, KRAS, and B-RAF for NSCLC treatment.

Abstract
Despite the recent advances in cancer treatment, lung cancer remains the leading cause of cancer mortality worldwide. Immunotherapies using immune checkpoint inhibitors (ICIs) achieved substantial efficacy in nonsmall cell lung cancer (NSCLC). Currently, most ICIs are still a monoclonal antibody (mAb). Using mAbs or antibody derivatives labeled with radionuclide as the tracers, immunopositron emission tomography (immunoPET) possesses multiple advantages over traditional 18F-FDG PET in imaging lung cancers. ImmunoPET presents excellent potential in detecting, diagnosing, staging, risk stratification, treatment guidance, and recurrence monitoring of lung cancers. By using radiolabeled mAbs, immunoPET can visualize the biodistribution and uptake of ICIs, providing a noninvasive modality for patient stratification and response evaluation. Some novel targets and associated tracers for immunoPET have been discovered and investigated. This Review introduces the value of immunoPET in imaging lung cancers by summarizing both preclinical and clinical evidence. We also emphasize the value of immunoPET in optimizing immunotherapy in NSCLC. Lastly, immunoPET probes developed for imaging small cell lung cancer (SCLC) will also be discussed. Although the major focus is to summarize the immunoPET tracers for lung cancers, we also highlighted several small-molecule PET tracers to give readers a balanced view of the development status.

Abstract
Background Lung cancer is still a prevalent and fatal neoplasm in developing countries.
In the last decades, chemotherapy (CHT) maintenance occupied an important
role in the treatment, as well as targeted therapies. We aimed to evaluate
the survival impact of targeted therapy in advanced lung cancer at a private
Peruvian institution (Oncosalud - AUNA). Methods We reviewed retrospectively medical records of patients with advanced-stage
non-small cell lung cancer (NSCLS) (clinical stage III-IV) who received CHT
and maintenance treatment with target therapy (TT) or CHT. The impact was
assessed by progression-free survival (PFS) and overall survival (OS) using
the Kaplan–Meier method, and comparisons of survival curves were performed
using log-rank or Breslow test and Cox model. Results The median age of the patients was 65 years. Clinical characteristics, as
well as the treatment type, showed no significant difference between the two
groups. The maintenance schedule in those receiving CHT was generally
pemetrexed (70%) and in those receiving TT was erlotinib (60.7%). In
patients receiving TT, the median PFS was 13 months compared to 7 months in
those receiving CHT; likewise, the median OS was 45 and 17 months,
respectively. The PFS and OS curves showed significant differences
(P < .05), achieving a better survival in subjects
treated with TT. Conclusion Progression-Free Survival and OS were superior in patients who received
targeted therapy than those treated only with CHT, the 2 years rate of PFS
and OS was nearly double to those who received only CHT-based
treatments.

Abstract
Lung cancer is the leading cause of cancer-associated deaths accounting for 24% of all cancer deaths. As a crucial phase of tumor progression, lung cancer metastasis is linked to over 70% of these mortalities. In recent years, exosomes have received increasing research attention in their role in the induction of carcinogenesis and metastasis in the lung. In this review, recent studies on the contribution of exosomes to lung cancer metastasis are discussed, particularly highlighting the role of lung tumor-derived exosomes in immune system evasion, epithelial-mesenchymal transition, and angiogenesis, and their involvement at both the pre-metastatic and metastatic phases. The clinical application of exosomes as therapeutic drug carriers, their role in antitumor drug resistance, and their utility as predictive biomarkers in diagnosis and prognosis are also presented. The metastatic activity, a complex multistep process of cancer cell invasion, survival in blood vessels, attachment and subsequent colonization of the host's organs, is integrated with exosomal effects. Exosomes act as functional mediating factors in cell-cell communication, influencing various steps of the metastatic cascade. To this end, lung cancer cell-derived exosomes enhance cell proliferation, angiogenesis, and metastasis, regulate drug resistance, and antitumor immune activities during lung carcinogenesis, and are currently being explored as an important component in liquid biopsy assessment for diagnosing lung cancer. These nano-sized extracellular vesicles are also being explored as delivery vehicles for therapeutic molecules owing to their unique properties of biocompatibility, circulatory stability, decreased toxicity, and tumor specificity. The current knowledge of the role of exosomes highlights an array of exosome-dependent pathways and cargoes that are ripe for exploiting therapeutic targets to treat lung cancer metastasis, and for predictive value assessment in diagnosis, prognosis, and anti-tumor drug resistance.

Toll-Like Receptor 7 Mediates Inflammation Resolution and Inhibition of Angiogenesis in Non-Small Cell Lung Cancer. Cancers (Basel) 2021; 13:cancers13040740. [PMID: 33578955 PMCID: PMC7916730 DOI: 10.3390/cancers13040740] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Revised: 02/01/2021] [Accepted: 02/07/2021] [Indexed: 12/26/2022] Open
Abstract
Simple Summary The progression of cancer is strictly linked to the formation of new blood vessels responsible for nutrition supply of the tumor. We identified TLR7 as an inhibitor of lung cancer vascularization. TLR7 is part of a large family of immune receptors that function as “sensors” of pathogen- and damage-derived signals. We found that TLR7 exerts antitumor functions in non-small cell lung cancer by inducing the production of specific molecules with inhibitory properties against new blood vessel formation. These molecules are known as specialized pro-resolving mediators (SPMs) and are derived from ω-3 and ω-6 fatty acids. We believe that the results obtained suggest novel potential targets and strategies to treat lung cancer. Abstract Pattern recognition receptors (PRR) promote inflammation but also its resolution. We demonstrated that a specific PRR—formyl peptide receptor 1 (FPR1)—sustains an inflammation resolution response with anti-angiogenic and antitumor potential in gastric cancer. Since toll-like receptor 7 (TLR7) is crucial in the physiologic resolution of airway inflammation, we asked whether it could be responsible for pro-resolving and anti-angiogenic responses in non-small cell lung cancer (NSCLC). TLR7 correlated directly with pro-resolving and inversely with angiogenic mediators in NSCLC patients, as revealed by a publicly available RNAseq analysis. In NSCLC cells, depletion of TLR7 caused an upregulation of angiogenic mediators and a stronger vasculogenic response of endothelial cells compared to controls, assessed by qPCR, ELISA, protein array, and endothelial cell responses. TLR7 activation induced the opposite effects. TLR7 silencing reduced, while its activation increased, the pro-resolving potential of NSCLC cells, evaluated by qPCR, flow cytometry, and EIA. The increased angiogenic potential of TLR7-silenced NSCLC cells is due to the lack of pro-resolving mediators. MAPK and STAT3 signaling are responsible for these activities, as demonstrated through Western blotting and inhibitors. Our data indicate that TLR7 sustains a pro-resolving signaling in lung cancer that inhibits angiogenesis. This opens new possibilities to be exploited for cancer treatment.

Abstract
BACKGROUND Non-small cell lung cancer (NSCLC) is one of the most lethal types of cancer with highly infiltrating. Chemotherapy is far from satisfactory, vasculogenic mimicry (VM) and angiogenesis results in invasion, migration and relapse. PURPOSE The objective of this study was to construct a novel CPP (mmp) modified vinorelbine and dioscin liposomes by two new functional materials, DSPE-PEG2000-MAL and CPP-PVGLIG-PEG5000, to destroy VM channels, angiogenesis, EMT and inhibit invasion and migration. METHODS AND RESULTS The targeting liposomes could be enriched in tumor sites through passive targeting, and the positively charged CPP was exposed and enhanced active targeting via electrostatic adsorption after being hydrolyzed by MMP2 enzymes overexpressed in the tumor microenvironment. We found that CPP (mmp) modified vinorelbine and dioscin liposomes with the ideal physicochemical properties and exhibited enhanced cellular uptake. In vitro and in vivo results showed that CPP (mmp) modified vinorelbine and dioscin liposomes could inhibit migration and invasion of A549 cells, destroy VM channels formation and angiogenesis, and block the EMT process. Pharmacodynamic studies showed that the targeting liposomes had obvious accumulations in tumor sites and magnificent antitumor efficiency. CONCLUSION CPP (mmp) modified vinorelbine plus dioscin liposomes could provide a new strategy for NSCLC.

Abstract
The purpose of this study was to assess the predictive value of angiogenic miRNAs for disease-free survival (DFS) and overall survival (OS) of patients with non-small cell lung cancer (NSCLC). In total, 196 patients with NSCLC (tumor lymph nodes metastasis (TNM) stage I-III) were enrolled and peripheral blood samples were collected. Total RNA was extracted from blood samples, and the relative expression levels of candidate miRNAs were evaluated by real time-polymerase chain reaction (RT-PCR). The median follow-up period was 56.7 months, and the final follow-up date was in August 2016. The median DFS of all patients was 30.0 (14.0-49.0) months, whereas the median OS was 41.5 (23.0-58.0) months. Furthermore, the 5-year DFS and OS rates were 11.3% and 32.3%, respectively. Kaplan-Meier (K-M) curves showed that high plasma miR-18a (P < 0.001), miR-20a (P < 0.001), miR-92a (P < 0.001), miR-126 (P < 0.001), miR-210 (P = 0.003), and miR-19a (P = 0.027) expressions levels correlated with a worse DFS. Moreover, patients with high plasma miR-18a, miR-20a, miR-92a, miR-210, and miR-126 expression levels had a shorter OS than patients with low expression levels of these miRNAs (all P <= 0.001). Furthermore, multivariate Cox regression analyses revealed that high plasma expression levels of miR-18a, miR-20a, and miR-92a as well as lymphatic node metastasis (all P < 0.001) were independent risk factors for both DFS and OS in patients with NSCLC. Thus, the circulating miR-18a, miR-20a, and miR-92a levels may serve as novel and promising prognostic biomarkers in patients with NSCLC.

Abstract
AIM Evaluate if serum levels of VEGF and Ang-2 are correlated in non-small-cell lung cancers (NSCLCs) and its implications in the diagnostic and prognostic of the disease. PATIENTS & METHODS Unselected cohort of 145 NSCLC patients and 30 control individuals. The serum levels of Ang-2 and VEGF of each patient were measured by ELISA prior to treatment. RESULTS & CONCLUSIONS Serum levels of Ang-2 and VEGF are correlated (p < 0.0001). High serum levels of Ang-2 and VEGF isolated and both combined (high(Ang-2/VEGF)) correlate with likelihood of presenting NSCLC (p = 0.016; p = 0.003; p < 0.0001, respectively). Serum levels of Ang-2 and high(Ang-2/VEGF) but not VEGF alone are independent prognostic factors (p = 0.001; p = 0.619; p = 0.005). High(Ang-2/VEGF) serum levels could be exploited as a new valuable integral biomarker in NSCLC.

Abstract
Purpose Data on the role of angiogenesis inhibitors (AIs) rechallenge in the treatment of advanced non-small-cell lung cancer (NSCLC) patients who previously received bevacizumab remain limited. We aim to investigate the efficacy of AIs in the treatment of advanced NSCLC in this setting. Methods Studies from PubMed, Web of Science, and abstracts presented at American Society of Clinical Oncology meeting up to December 1, 2014 were searched to identify relevant studies. Eligible studies included prospective randomized controlled trials evaluating AIs in advanced NSCLC, with survival data on patients who previously received bevacizumab. The end points were overall survival and progression-free survival. Statistical analyses were conducted by using either random effects or fixed effect models according to the heterogeneity of included studies. Results A total of 452 patients with advanced NSCLC who previously received bevacizumab were identified for analysis. The meta-analysis results demonstrated that AI rechallenge significantly improved progression-free survival (hazard ratio: 0.72, 95% confidence interval: 0.58–0.89, P=0.002) when compared to non-AI containing regimens. Additionally, a nonsignificant improvement in overall survival was also observed in advanced NSCLC in this setting (hazard ratio: 0.82, 95% confidence interval: 0.65–1.03, P=0.087). Similar results were also observed in subgroup analysis according to treatment regimens. Conclusion The findings of this study suggest that NSCLC patients who relapsed after a first-line bevacizumab-containing chemotherapy obtain improved clinical benefits from AI rechallenge. Prospective clinical trials investigating the role of AI rechallenge in this setting are recommended.

Abstract
As angiogenesis is an important target for antitumour drugs, the agents that inhibit angiogenesis may help reduce the use of chemotherapy by blocking tumour blood supply. In this study, we investigated a potent angiogenesis inhibitor, ASC, a steroidal saponin compound, which has been purified from Ophitopogin japonicus (L.f) Ker.-Gawl. Our observations showed that ASC significantly suppressed human umbilical vein endothelial cell (HUVECs) growth both in vitro and in vivo. This may be resulted from the G2/M cell cycle arrest effects of ASC. Moreover, ASC inhibited HUVECs invasion and tube formation processes, which were associated with endothelial cells remodelling. A mechanism study indicated that ASC down-regulated the expression of Src tyrosine kinase, further leading to the blockage of Akt-dependent matrix metalloproteinases (mainly for MMP-9) signalling pathway, which was functionally associated with angiogenic blood vessels. Finally, ASC significantly inhibited angiogenesis and MMPs/VEGF expression in the subcutaneously injected matrigel in C57/BL mice. These findings suggest that ASC might be a potential drug candidate in anti-angiogenesis and anticancer therapies.

Abstract
Non-small cell lung cancer (NSCLC) is the most common cancer and the leading cause of death from cancer worldwide. Antiangiogenic strategies directed towards tumor stroma are becoming gold standard in NSCLC treatment and researchers have been searching for biomarkers to identify patients for whom therapy with antiangiogenic inhibitors may be most beneficial and the importance of these as prognostic factors in NSCLC. The purpose of this study was to evaluate the prognostic value of circulating Ang-2 mRNA levels prior to treatment in NSCLC patients. The mRNA levels were determined by quantitative real-time PCR in the peripheral blood of 92 NSCLC patients. Our results demonstrate that patients with high circulating Ang-2 mRNA levels have diminished overall survival when compared to those with low mRNA levels (20.3 months vs 34.3 months, respectively; Log Rank Test, p = 0.016), when considering all NSCLC stages and this difference is even bigger when considering only patients with stage IV (15.9 months vs 31.3 months, respectively; Log Rank Test, p = 0.036). Moreover, circulating Ang-2 mRNA levels independently determine overall survival, and the concordance (c) index analysis showed that the definition of a nomogram that contains information regarding tumor stage, patients' smoking status and circulating Ang-2 mRNA levels present an increased capacity to predict overall survival in NSCLC patients (c-index 0.798). These results suggest that this nomogram could serve as a unique and practical tool to determine prognosis in NSCLC, not relying on the availability of adequate surgical or biopsy specimens of NSCLC. Attending to our results, the circulating Ang-2 mRNA levels should also be included in the design of preclinical studies and clinical trials involving antiangiogenic drugs targeting Ang-2, to guide adequate patient stratification and dose selection and increasing the likelihood of benefit to a level that is acceptable to patients and clinicians.
