[PMID: 38765119 PMCID: PMC11101798 DOI: 10.1016/j.heliyon.2024.e30646] [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: 06/28/2023] [Revised: 05/01/2024] [Accepted: 05/01/2024] [Indexed: 05/21/2024] Open
Abstract
Background Lung adenocarcinoma is one of the leading causes of cancer-related deaths because of the lack of early specific clinical indicators. MicroRNAs (miRNAs) have become the focus in lung cancer diagnosis. Further studies are required to explore miRNA expression in the serum of lung adenocarcinoma patients and their correlation with therapy and analyse specific messenger RNA targets to improve the specificity and sensitivity of early diagnosis. Methods The Toray 3D-Gene miRNA array was used to compare the expression levels of various miRNAs in the sera of patients with lung adenocarcinoma and healthy volunteers. Highly expressed miRNAs were selected for further analysis. To verify the screening results, serum and pleural fluid samples were analysed using qRT-PCR. Serum levels of the miRNAs and their correlation with the clinical information of patients with lung adenocarcinoma were analysed. The functions of miRNAs were further analysed using the Kyoto Encyclopedia of Gene and Genomes and Gene Ontology databases. Results Microarray analysis identified 60 and 50 miRNAs with upregulated and downregulated expressions, respectively, in the serum of patients with lung adenocarcinoma compared to those in healthy individuals. Using qRT-qPCR to detection of miRNAs expression in the serum or pleural effusion of patients with early and advanced lung adenocarcinoma, we found that miR-4433a-3p could be used as a diagnostic marker and therapeutic evaluation indicator for lung adenocarcinoma. Serum of miR-4433a-3p levels significantly correlated with the clinical stage. miR-4433a-3p may be more suitable than other tumour markers for the early diagnosis and evaluation of therapeutic effects in lung adenocarcinoma. miR-4433a-3p may affect tumour growth and metastasis by acting on target genes (PIK3CD, UBE2J2, ICMT, PRDM16 and others) and regulating tumour-related signalling pathways (MAPK signal pathway, Ras signalling pathway and others). Conclusion miR-4433a-3p may serve as a biomarker for the early diagnosis of lung adenocarcinoma and monitoring of therapeutic effects.

Abstract
A circular RNA (circRNA) is a non-coding RNA (ncRNA) derived from reverse splicing from pre-mRNA and is characterized by the absence of a cap structure at the 5' end and a poly-adenylated tail at the 3' end. Owing to the development of RNA sequencing and bioinformatics approaches in recent years, the important clinical value of circRNAs has been increasingly revealed. Circ_0067934 is an RNA molecule of 170 nucleotides located on chromosome 3q26.2. Circ_0067934 is formed via the reverse splicing of exons 15 and 16 in PRKCI (protein kinase C Iota). Recent studies revealed the upregulation or downregulation of circ_0067934 in various tumors. The expression of circ_0067934 was found to be correlated with tumor size, TNM stage, and poor prognosis. Based on experiments with cancer cells, circ_0067934 promotes cancer cell proliferation, migratory activity, and invasion when overexpressed or downregulated. The potential mechanism involves the binding of circ_0067934 to microRNAs (miRNAs; miR-545, miR-1304, miR-1301-3p, miR-1182, miR-7, and miR-1324) to regulate the post-transcriptional expression of genes. Other mechanisms include inhibition of the Wnt/β-catenin and PI3K/AKT signaling pathways. Here, we summarized the biological functions and possible mechanisms of circ_0067934 in different tumors to enable further exploration of its translational applications in clinical diagnosis, therapy, and prognostic assessments.

Abstract
Objective Non-small cell lung cancer (NSCLC) has high degree of malignance and proneness to recurrence and metastasis. The aim of this study was to analyse the risk factors influencing the chemotherapy compliance and survival status of elderly NSCLC patients. Methods The clinical data of 110 patients admitted from January 2014 to March 2018 were retrospectively analysed. They were assigned to non-chemotherapy (n=25), partial chemotherapy (n=30) and complete chemotherapy (n=55) groups according to chemotherapy compliance, and followed up until March 2021. Their clinicopathological characteristics were investigated by univariate analysis and then multivariate Cox regression analysis. The survival rates were compared by Kaplan-Meier survival curve and log-rank test. Results Among the 110 NSCLC patients, 25 did not receive chemotherapy, 30 underwent partial chemotherapy and 55 received complete chemotherapy. Educational level, pathological tumor-node-metastasis (TNM) stage, pathological type, surgical approach, place of residence, payment mode and chemotherapy stage were independent risk factors influencing the chemotherapy compliance (P<0.05). Conclusion Particular attention should be paid to improving the chemotherapy compliance of patients with low educational level, late TNM stage, medical history of squamous cell carcinoma, history of thoracotomy, living in rural areas and no medical insurance, and those in the recurrence period or consolidation period of chemotherapy.

Abstract
BACKGROUND Lung adenocarcinoma (LUAD) is a prevalent subtype of lung cancer associated with high mortality rates. We aimed to utilize single-cell multiomics analysis to identify the key molecules involved in ubiquitination modification, which plays a role in LUAD development and progression. METHODS We use a systematic approach to analyze LUAD-related single-cell and bulk transcriptome datasets from Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) databases. Single-cell RNA sequencing (scRNA-seq) data were normalized, clustered, and annotated with the Seurat package in R. InferCNV was used to distinguish malignant from epithelial cells, and AUCell evaluated the area under the curve (AUC) score of ubiquitination-related enzymes. Survival and differential analyses identified significant molecular markers associated with ubiquitination. PSMD14 expression was confirmed using reverse-transcription quantitative polymerase chain reaction (RT-qPCR) and Western blot assays, and its knockdown cell lines were assessed for effects on cellular processes and tumor formation in mice. PSMD14's interacting proteins were predicted, and its impact on AGR2 protein half-life and ubiquitination was evaluated. Rescue experiments involving PSMD14 overexpression and AGR2 silencing assessed their impact on malignant behaviors. RESULTS By means of single-cell sequencing analysis, we probed the ubiquitination modification landscape in the LUAD microenvironment. Malignant cells had elevated scores for enzymes and ubiquitin-binding domains compared to normal epithelial cells, with 53 ubiquitination-related molecules showing prognostic disparities. FGR, PSMD14, and ZBTB16 were identified as genes with prognostic significance, with PSMD14 showing higher expression in epithelial and malignant cells. Two missense mutation sites were identified in PSMD14, which had a high copy number amplification ratio and positive correlation with messenger RNA (mRNA) expression. PSMD14 expression and tumor stage were found to be independent prognostic factors, and interfering with PSMD14 expression reduced the malignant behavior of LUAD cells. PSMD14 was found to bind to AGR2 protein and reduce its ubiquitination, leading to increased AGR2 stability. Knockdown of AGR2 inhibited the enhancement of cell viability, invasion, and migration resulting from PSMD14 overexpression. CONCLUSIONS This study examined ubiquitination modifications in LUAD using sequencing data, identifying PSMD14's critical role in malignancy regulation and its potential as a prognostic and therapeutic biomarker. These insights enhance understanding of LUAD mechanisms and treatment.

Abstract
Background Non-small cell lung cancer (NSCLC) is the most common malignancy in lung cancer, with a low survival rate and unfavorable prognosis. Dysregulated long non-coding RNAs (lncRNAs) play vital functions in tumor progression. This study intended to probe the expression pattern and function of HOXD-AS2 in NSCLC. Methods Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to analyze the expression of HOXD-AS2, miR-3681-5p, CCR1, mRNA-decapping enzyme 1A (DCP1A), and PPP3R1. Cell viability, migration, and invasion were separately examined via 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide (MTT) and transwell experiments. Luciferase reporter assay was conducted to evaluate the binding of miR-3681-5p with HOXD-AS2 or DCP1A. Protein expression of DCP1A was assessed via Western blot. NSCLC animal models were constructed through injection of H1975 cells transfected with lentivirus (LV)-sh-HOXD-AS2 into nude mice, followed by hematoxylin and eosin (HE) staining and immunohistochemistry (IHC) analysis. Results In this study, HOXD-AS2 was upregulated in NSCLC tissues and cells, and high HOXD-AS2 predicted short overall survival (OS). Downregulation of HOXD-AS2 could impair the proliferation, migration, and invasion abilities of H1975 and A549 cells. MiR-3681-5p was shown to bind with HOXD-AS2 and be lowly expressed in NSCLC. Suppression of miR-3681-5p could abolish the inhibitory effect of HOXD-AS2 silencing on proliferation, migration, and invasion. DCP1A was screened as the target of miR-3681-5p and its overexpression could rescue miR-3681-5p upregulation-repressed proliferation, migration, and invasion activities. Moreover, animal experiments affirmed that HOXD-AS2 promoted tumor growth in vivo. Conclusions HOXD-AS2 modulates the miR-3681-5p/DCP1A axis to boost the progression of NSCLC, which founds the basis of HOXD-AS2 as a new diagnostic biomarker and molecular target for NSCLC therapy.

Abstract
CONTEXT The antitumor effects of caudatin have been explored in multiple cancers, but the research on lung cancer has not been fully understood. OBJECTIVE We explored the effects of caudatin on non-small cell lung cancer (NSCLC) in vitro and in vivo. MATERIALS AND METHODS In the in vitro experiments, 0, 25, 50 and 100 μM of caudatin were selected to examine the effects on stemness and glycolysis. Subcutaneous tumour xenografts were constructed by injecting the nude mice (BALB/C) with 5 × 106 H1299 cells. In the in vivo experiments, all nude mice were divided into the caudatin group (50 mg/kg/day, n = 5) and the sham group (equal amount of DMSO, n = 5). RESULTS The IC50 of caudatin for H1299 and H520 cells was 44.68 μM and 69.37 μM, respectively. Compared with caudatin 0 μM group, cell apoptosis rate was increased about 10 times and cell stemness was decreased by 75-85% in caudatin 100 μM group. Glucose uptake (65-80% reduction), lactic acid production (75-80% reduction), ATP level (70-80% reduction) and the expression of HK2 and LDHA (75-85% reduction) were decreased in caudatin 100 μM group. The expression of Raf/MEK/ERK pathway related proteins was decreased to 20-25% by caudatin. Tumour weight (about 70% reduction) and the expression of stemness, glycolysis and Raf/MEK/ERK pathway related proteins (about 50-75% reduction) were suppressed by caudatin in vivo. DISCUSSION AND CONCLUSIONS We revealed that caudatin blocked stemness and glycolysis in NSCLC for the first time. More experiments about exact dosage of caudatin in vivo should be conducted.

Abstract
OBJECTIVE To explore the efficacy and safety of thoracoscopic resection for early-stage non-small cell lung cancer (NSCLC). METHODS A total of 110 patients with early-stage NSCLC admitted to Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology between August 2017 and December 2019 were enrolled and retrospectively analysed. Among them, 60 patients receiving thoracoscopic resection for lung cancer (LC) were assigned to the research group (Res group) and another 50 patients treated with routine open radical resection for LC were included in the control group (Con group). The following items of the two groups were evaluated and compared: treatment efficacy, operation indexes, VAS score, lung function, lung capacity, complications, 2-year tumour-free survival rate, 2-year survival rate, and quality of life (QoL). RESULTS The Res group showed significantly better efficacy, and lower incidence of complications and VAS score than the Con group. In addition, patients in the Res group experienced less intraoperative blood loss, earlier anal exhaust, shorter hospital stay and indwelling time of drainage tube as well as less drainage volume. Furthermore, better recovery in pulmonary function and lung capacity, and significantly higher 2-year tumour-free survival rate, 2-year survival rate as well as postoperative QoL were noted in the Res group compared with the Con group. CONCLUSION Thoracoscopic resection for LC is effective in the treatment of patients with early-stage NSCLC. It can substantially shorten the hospital stay and indwelling time of drainage tube and reduce drainage volume and blood loss, with high safety.

Abstract
Objective To assess the clinical efficacy of thoracoscopic lobectomy and segmentectomy in the treatment of patients with early-stage lung cancer. Methods A total of 70 patients with early-stage non-small cell lung cancer who were treated in our hospital from April 2018 to May 2020 were recruited and assigned at a ratio of 1 : 1 to receive either segmentectomy (observation group) or lobectomy (control group). Outcome measures included clinical efficacy, surgery-related indicators, pulmonary function indicators (forced vital capacity (FVC) and forced expiratory volume in one second (FEV1)), postoperative complications, and recurrence and metastasis. Results There was no significant difference in the clinical efficacy between the two groups (P > 0.05). Segmentectomy was associated with a longer operation time and shorter hospital stay compared to lobectomy (P < 0.05). There was no statistical significance in the amount of intraoperative blood loss and the number of lymph nodes dissected (P > 0.05). Segmentectomy resulted in significantly higher FVC and FEV1 levels in patients compared to lobectomy (P < 0.05). There was no significant difference in the incidence of postoperative complications between the two groups (P > 0.05). The two groups of patients were followed up for 12 months after the operation, and there was no recurrence or metastasis in either group. Conclusion The two surgical methods have similar efficacy and safety profiles, but for the treatment of patients with early-stage lung cancer, thoracoscopic segmentectomy is associated with a shorter hospital stay and better protection of the lung function of patients compared to lobectomy.
