MicroRNAs are small, non-coding RNA molecules that can complementarily bind to the mRNA 3'-UTR region to regulate the gene expression by transcriptional repression or induction of mRNA degradation. Increasing evidence suggests a new mechanism by which miRNAs may regulate target gene expression by binding in promoter and amino acid coding regions. Most of(More)
BACKGROUND & AIMS Cancer cells often lose contact inhibition to undergo anchorage-independent proliferation and become resistant to apoptosis by inactivating the Hippo signaling pathway, resulting in activation of the transcriptional co-activator yes-associated protein (YAP). However, the oncogenic mechanisms of YAP activity are unclear. METHODS By using(More)
Mesenchymal stromal cells (MSCs) are promising candidates for innovative cell therapeutic applications. For clinical scale manufacturing regulatory agencies recommend to replace fetal bovine serum (FBS) commonly used in MSC expansion media as soon as equivalent alternative supplements are available. We already demonstrated that pooled blood group AB human(More)
OBJECTIVE The development of osteoarthritis (OA) may be caused by activation of hypertrophic differentiation of articular chondrocytes. Healthy articular cartilage is highly resistant to hypertrophic differentiation, in contrast to other hyaline cartilage subtypes, such as growth plate cartilage. The purpose of this study was to elucidate the molecular(More)
Because the vagus nerve is implicated in control of inflammation, we investigated if brain death (BD) causes impairment of the parasympathetic nervous system, thereby contributing to inflammation. BD was induced in rats. Anaesthetised ventilated rats (NBD) served as control. Heart rate variability (HRV) was assessed by ECG. The vagus nerve was electrically(More)
Chromosomal aberrations are known to have an impact on the initiation and progression of oral squamous cell carcinoma (OSCC), but individual genes involved in OSCC pathogenesis are poorly described. To elucidate the molecular events underlying oral carcinogenesis, a set of primary OSCC were screened for distinct genetic imbalances by means of array-based(More)
Chromosomal band 11q13 is frequently amplified in oral squamous cell carcinoma (OSCC) and assumed to be critically involved in tumor initiation and progression by proto-oncogene activation. Though cyclin D1 (CCND1) is supposed to be the most relevant oncogene, several additional putative candidate genes are inside this chromosomal region, for which their(More)
miRWalk (http://mirwalk.uni-hd.de/) is a publicly available comprehensive resource, hosting the predicted as well as the experimentally validated microRNA (miRNA)-target interaction pairs. This database allows obtaining the possible miRNA-binding site predictions within the complete sequence of all known genes of three genomes (human, mouse, and rat).(More)
MicroRNAs (miRNAs) and copy number variations (CNVs) are two newly discovered genetic elements that have revolutionized the field of molecular biology and genetics. By performing in silico whole genome analysis, we demonstrate that both the number of miRNAs that target genes found in CNV regions as well as the number of miRNA-binding sites are significantly(More)
OBJECTIVE The use of mesenchymal stem cells (MSCs) for cartilage regeneration is hampered by lack of knowledge about the underlying molecular differences between chondrogenically stimulated chondrocytes and MSCs. The aim of this study was to evaluate differences in phenotype and gene expression between primary human chondrocytes and MSCs during chondrogenic(More)
