Correlation of short leukocyte telomeres and oxidative stress with the presence and severity of lung cancer explored by principal component analysisBelić, Milica ...Lung cancer (LC) is the second most common malignancy and leading cause of cancer death. The potential “culprit” for local and systemic telomere shortening in LC patients is oxidative stress. We ... investigated the correlation between the peripheral blood leukocyte (PBL) telomere length (TL) and the presence/severity of LC and oxidative stress, and its usefulness as LC diagnostic marker. PBL TL was measured in 89 LC patients and 83 healthy subjects using the modified Cawthon RTq-PCR method. The relative PBL TL, found to be a potential diagnostic marker for LC with very good accuracy (P < 0.001), was significantly shorter in patients compared to the control group (CG) (P < 0.001). Significantly shorter telomeres were found in patients with LC TNM stage IV than in patients with stages I-III (P = 0.014), in patients without therapy compared to those on therapy (P = 0.008), and in patients with partial response and stable/progressive disease compared to those with complete response (P = 0.039). The total oxidant status (TOS), advanced oxidation protein products (AOPP), prooxidant-antioxidant balance (PAB) and C-reactive protein (CRP) were significantly higher in patients compared to CG (P < 0.001) and correlated negatively with TL in both patients and CG (P < 0.001). PCA showed a relation between PAB and TL, and between the EGFR status and TL. Oxidative stress and PBL telomere shortening are probably associated with LC development and progression.Vir: Folia biologica. - ISSN 0015-5500 (Vol. 69, iss. 2, 2023, str. 59-68)Vrsta gradiva - članek, sestavni del ; neleposlovje za odrasleLeto - 2023Jezik - angleškiCOBISS.SI-ID - 176854531
