Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death among women worldwide. Metastasis remains a major challenge for the clinical management and prognosis of patients with cancer. The metalloprotease MMP-9 plays a critical role in the first step of metastasis through extracellular matrix degradation. In this study, our goal was to determine the effect of epigenetic...
Maturity Onset Diabetes of the Young (MODY) is a heterogeneous group of genetic diseases characterized by a primary defect in insulin secretion and hyperglycemia, non-ketotic disease, monogenic autosomal dominant mode of inheritance, age at onset less than 25years, and lack of auto-antibodies. It accounts for 2–5% of all cases of non-type 1 diabetes. MODY subtype 2 is caused by mutations in the glucokinase...
MicroRNAs (miRNAs) are short non-coding RNA transcripts that have the ability to regulate the expression of target genes, and have been shown to influence the development of various tumors. The purpose of our study is to identify aberrantly expressed miRNAs in retinoblastoma for the discovery of potential therapeutic targets for this disease, and to gain a greater understanding of the mechanisms driving...
Several aspects of epigenetics are strongly linked to non-coding RNAs, especially small RNAs that can direct the cytosine methylation and histone modifications that are implicated in gene expression regulation in complex organisms. A fundamental characteristic of epigenetics is that the same genome can show alternative phenotypes, which are based in different epigenetic states. Some of the most studied...
In the last ten years, several RNAs with no protein-coding potential have been accumulating in RNA databases and are in need of further molecular characterization. At the same time, examples of non-coding RNAs (ncRNAs) such as microRNAs, small RNAs, small interfering RNAs (siRNAs) and medium/large RNAs with various functions have been described in the literature. Recent evidence points to a widespread...
The completion of the human, mouse and other eukaryotic genomes were important scientific milestones, but they were just small steps towards the understanding of eukaryotic biology. Recent transcriptome analysis and different experimental approaches have identified a surprisingly large number of non-coding RNAs (ncRNAs) in eukaryotic cells. ncRNAs comprise microRNAs, anti-sense transcripts and other...
