The objective of this study was to investigate the prognostic significance of the frequency of primary cilia (PC) and β-catenin expression in 218 patients (pts) with non-small cell lung cancer (NSCLC), including 125 pts with adenocarcinoma and 93 pts with squamous cell carcinoma. In the whole group of 218 pts with NSCLC, overall survival (OS) was significantly inferior among pts with present PC than without PC (p=0.024) and with higher cytoplasmic β-catenin expression (25-75%) than with lower cytoplasmic β-catenin expression (<25%) (p=0.

DNA methylation is recognized as an early event in cancer initiation and progression. This review aimed to compare the methylation status of promoter regions in selected genes across different histological subtypes of non-small cell lung cancer (NSCLC), including adenocarcinoma, squamous cell carcinoma, large cell carcinoma, and the rare but highly aggressive large-cell neuroendocrine carcinoma (LCNEC). A comprehensive literature search was conducted in the PubMed database until August 17, 2024, using standardized keywords to identify reports on promoter methylation in NSCLC.

MTHFD2 is highly overexpressed in breast cancer tissues, indicating that it might be used as a target in breast cancer treatment. This study aims to determine the role of MTHFD2 in breast cancer cell proliferation and the molecular pathways involved. In order to investigate MTHFD2 gene expression and its downstream pathways in breast cancer, we started our inquiry with a bioinformatics analysis.

Pediatric central nervous system (CNS) tumors represent 20-25% of childhood malignancies, with 35-40 new cases annually in Slovakia. Despite treatment advances, high mortality and poor quality of life in a lot of cases persist. This study assesses the clinical features, treatment modalities, and survival rates of pediatric CNS tumor patients in the single largest center in Slovakia.
