RESUMO
The objective of the current investigation was to investigate the diagnostic utility of the serum concentrations and mutational status of TGFß1, SMAD2, CTNNß1, and Wnt3a. and the expression levels of humanrelated genes in patients with non-small cell lung cancer (NSCLC). The serum concentrations were determined using the ELISA technique, and PCR for genotype variations of TGFß1, SMAD2, CTNNß1, and Wnt3a were examined using Sanger sequencing in tissue samples obtained from 93 patients with NSCLC and 84 healthy individuals for blood, and 20 Formalin Fixed Parafï¬n Embedded (FFPE) from normal samples dissected adjacent to the tumour. The findings of the current investigation indicate that individuals diagnosed with NSCLC exhibited significant elevation in the serum levels of CEA and CYFRA21-1, as well as TGFß1, SMAD2, CTNNß1, and Wnt3a. In total, 325 mutations in four trialled genes (243 mutations in TGFß1, 24 mutations in SMAD2,47 mutation Wnt3a and 11 mutations in CTNNß1) were identified in patients with NSCLC. Furthermore, all mutations were recorded in adenocarcinoma, not squamous and normal adjacent tumour cells. CYFRA21-1 and CEA are more significant between NSCLC and HC, gender, and NSCLC types (p<0.001). In detail, TGFß1 exhibited the highest rate of mutations among other genes and three types of genomic mutations. Elevated levels and genetic polymorphisms of TGFß1, SMAD2, CTNNß1, and Wnt3a may play crucial functions in the pathogenesis and angiogenesis of non-small cell lung cancer (NSCLC). These biomarkers might play a role in future immunologic response and pharmacologically targeted NSCLC therapy.

Introduction: Biomarkers play a crucial role in evaluating the prognosis, diagnosis, and monitoring of non-small cell lung cancer (NSCLC). The aim of this study was to compare the levels of inflammatory and remodelling biomarkers among patients with NSCLC and healthy controls (HCs) and to investigate the correlation between these biomarkers. Material and methods: Blood samples were taken from 93 NSCLC and 84 HCs. Each sample was analysed for the inflammatory biomarkers transforming growth factor ß1 (TGF-ß1), mothers against decapentaplegic homolog 2 (SMAD2) and the remodelling biomarkers Wingless-related integration site (Wnt3a) and α-catenin (CTNN-ß1). Results: The patients with NSCLC had significantly higher levels of all the measured biomarkers. In the NSCLC patients, TGF-ß1 correlated significantly with SMAD2 (r = 0.34, p = 0.0008), Wnt3a (r = 0.328, p = 0.0013), and CTNN-ß1 levels (r = 0.30, p = 0.004). SMAD2 correlated significantly with CTNN-ß1 (r = 0.546, p = 0.0001) and Wnt3a (r = 0.598, p = 0.0001). CTNN-ß1 level also correlated with the level of Wnt3a (r = 0.61, p = 0.0001). No correlation was found between biomarkers and symptom scores. Discussion: In this study, patients with NSCLC had higher inflammatory and remodelling biomarker levels than HCs. In the NSCLC, there were significant associations between inflammatory and remodelling biomarkers. This indicates that measuring biomarkers could be valuable in the workup of NSCLC patients. Conclusions: Our investigation showed that inflammatory and remodelling biomarkers might play a role in future immunologic response and pharmacologically targeted NSCLC therapy.
