Introduction: Long non-coding RNAs play an important role in regulating gene expression, RNA processing, histone modification, and rearrangement of chromatin genes. These molecules can also be involved in many biological processes, such as organogenesis, cell differentiation, development, genome imprinting, quantitative compensation, and tumorigenesis. High expression of MALAT1 (a type of lncRN...
Germline mutations in the human breast cancer genes BRCA1 and BRCA2 account for a substantial proportion of familial, early-onset breast and ovarian cancers. The present study reports a novel disease-causing BRCA1 mutation, nucleotide 3020insCT/c.2901insCT, in a 55-year-old Spanish female with breast and ovarian cancer. This frameshift mutation creates a premature stop codon at amino acid 1000,...
Infection and chronic inflammation contribute to about 1 in 4 of all cancer cases. Mediators of the inflammatory response, e.g., cytokines, free radicals, prostaglandins and growth factors, can induce genetic and epigenetic changes including point mutations in tumor suppressor genes, DNA methylation and post-translational modifications, causing alterations in critical pathways responsible for m...
Background: Ovarian cancer is a leading metastatic disease. The epithelial ovarian cancer is one of the most common malignant cancers that usually remains asymptomatic up to metastasis stages, and most patient when diagnosed are in the advanced stage of the disease. Studies have shown that in the majority of epithelial cancers mesenchymal factor expression such as Vimentin increases, and the ep...
background: the aim of this study was to clarify the mechanism by which lactobacilli exert their cytotoxic effects on cervical cancer cells. in addition, we aimed to evaluate the effect of lactobacilli on the expression of human papilloma virus (hpv) oncogenes. materials and methods: in this experimental study, using quantitative real-time polymerase chain reaction (pcr), we analyzed the expres...
Background: Iron adsorption factors are among the most important virulence factors of P. mirabilis causing urinary tract infections. The aim of the present study was the evaluation of the frequency and nucleotide sequence of genes encoding the iron adsorption genes in Proteus mirabilis isolated from patients with urinary tract infections. Materials and Methods: In total, 100 P. mirabilis isola...
background: cancer/testis antigens (ctas) are members of a group of proteins which are normally expressed in testis germ cells and to a lesser extent in the ovaries. because of recent reports about their aberrant and specific expression in some tumoral tissues, they may play a role as new candidates for targeted therapy. therefore, the study of the expression pattern of these biomarkers and its...
objective: breast cancer is the second leading cause of cancer death in women. cisplatin is a traditional cancer drug commonly used in chemotherapy for killing cancer cells. modulation at the mrna levels of apoptotic related genes often correlate with the sensitivity of various types of cancer cells to chemotherapeutic agents. nanoparticulate drug delivery systems are being developed to effecti...
Recent studies applying high-throughput sequencing technologies have identified several recurrently mutated genes and pathways in multiple cancer genomes. However, transcriptional consequences from these genomic alterations in cancer genome remain unclear. In this study, we performed integrated and comparative analyses of whole genomes and transcriptomes of 22 hepatitis B virus (HBV)-related he...
