Triple‑negative breast cancer (TNBC) has a poorer prognosis than other subtypes; therefore, identifying markers of early recurrence is important. The present study aimed to establish liquid biopsy protocol for droplet digital PCR‑based detection frequently mutated genes in patients with TNBC. Tumor DNA from 36 TNBC who relapsed within 2 years after surgical resection was retrospectively analyze...

In non-small cell lung cancer (NSCLC), epidermal growth factor receptor (EGFR) mutational analysis is an excellent predictor of responsiveness to treatment with tyrosine kinase inhibitors, such as gefitinib. In up to 80% of NSCLCs, cytologic samples or endoscopic biopsies are the only specimens available for molecular analysis, but PCR amplification of DNA from small fixed and paraffin-embedded...

Knowledge on mutation processes is central to interpreting genetic analysis data as well as understanding the underlying nature of almost all evolutionary phenomena. However, studies on genome-wide mutational spectrum and dynamics in fungal pathogens are scarce, hindering our understanding of their evolution and biology. Here, we explored changes in the phenotypes and genome sequences of the ri...

PURPOSE The presence of diffuse anaplasia in Wilms tumours (DAWT) is associated with TP53 mutations and poor outcome. As patients receive intensified treatment, we sought to identify whether TP53 mutational status confers additional prognostic information. PATIENTS AND METHODS We studied 40 patients with DAWT with anaplasia in the tissue from which DNA was extracted and analysed for TP53 muta...

Background: Cutaneous melanoma (CM) is the most aggressive subtype of skin cancer, with increasing incidence over the past several decades. DNA methylation is a key element of several biological processes such as genomic imprinting, cell differentiation and senescence, and deregulation of this mechanism has been implicated in several diseases, including cancer. In order to understand the relati...

Recent advances in DNA sequencing techniques have led to an increase in the identification of single nucleotide polymorphisms (SNPs) in BRCA1 and BRCA2 genes, but no further information regarding the deleterious probability of many of them is available (Variants of Unknown Significance/VUS). As a result, in the current study, different sequence- and structure-based computation...
