BACKGROUND Although the development of novel diagnostic and treatment strategies concerning laryngeal cancer is highly intensive, the survival rate remains virtually unchanged. Small non-coding RNAs appear to be very promising biomarkers - and so remain the focus of extensive investigation in laryngeal cancer. OBJECTIVE We examined the expression of five miRNA and five genes related to cancer...

BACKGROUND The aim of this study was to investigate the association between polymorphism of the cytochrome P450 1B1 (CYP1B1) gene, a metabolic enzyme gene, and the susceptibility to laryngeal cancer among the Chinese Han population. MATERIAL/METHODS In a case-control study, we investigated polymorphisms in the CYP1B1 gene (rs10012, rs1056827, and rs1056836) with a real-time quantitative polym...

It remains unclear whether the Glutathione S-transferase M1 (GSTM1) null genotype influence laryngeal cancer development. This study aimed to investigate the interactions among GSTM1 genotype with regard to laryngeal cancer development. We searched online electronic databases (PubMed, EMBASE and CNKI). The strength of association between the GSTM1 genotype and laryngeal cancer risk was assessed...

Although targeting radioresistant tumor cells is essential for enhancing the efficacy of radiotherapy, the signals activated in resistant tumors are still unclear. This study shows that ERp57 contributes to radioresistance of laryngeal cancer by activating STAT3. Increased ERp57 was associated with the radioresistant phenotype of laryngeal cancer cells. Interestingly, increased interaction betw...

Laryngeal cancer is the major malignant tumor affecting the upper respiratory tract. Previous studies have reported on the association between XRCC1 genetic polymorphisms and risk of laryngeal cancer, but with conflicting results. In this study, we attempted to assess the association between XRCC1 Arg194Trp, Arg280His and Arg399Gln polymorphisms and risk of laryngeal cancer in a Chinese populat...

Accumulating evidence has shown that aberrant lncRNA expression plays an oncogenic or tumor-suppressive role in the tumorigenesis of laryngeal cancer. However, the prognostic roles of lncRNAs in laryngeal cancer recurrence are still poorly understood. In this study, we obtained lncRNA expression profiles of 109 patients with laryngeal cancer by mining previously published gene expression microa...

miR-27a regulates cell differentiation in a variety of diseases. However, whether and how miR-27a participates in laryngeal cancer cell differentiation remains unknown. Therefore, we explored role and molecular mechanism of miR-27a in laryngeal cancer differentiation in the study. We found that miR-27a expression was inversely correlated with laryngeal cancer differentiation degree based on the...

PURPOSE It has been suggested that selenium deficiency is a risk factor for several cancer types. We conducted a case-control study in Szczecin, a region of northwestern Poland, on 95 cases of lung cancer, 113 cases of laryngeal cancer and corresponding healthy controls. METHODS We measured the serum level of selenium and established genotypes for four variants in four selenoprotein genes (GP...

The aim of this study was to determine the possible relevance of the retinoblastoma protein (pRb) expression in laryngeal cancer as a prognostic criterion and to analyse the correlation between the expression and clinical and pathological features vs. survival rates. The immunohistochemical staining was used to detect the expression of pRb in 130 samples of laryngeal cancer and in 22 specimens ...
