Background and Aims: Epicardial adipose tissue, exosomes, miRNAs have important activities in atherosclerosis. The purpose of this study was to establish miRNA expression profiles epicardial tissue-derived exosomes patients with coronary Methods: Biopsies tissue were obtained from without artery disease (CAD, n = 12 NCAD, 12) during elective open-heart surgeries. Tissue incubated DMEM-F12 for 2...

Many physical and chemical factors can influence the Nrf2 signaling pathway, its deregulation has been associated with various disease states. Keap1 molecules are key elements that regulate response under cell stress conditions. Hence, aim of research was to assess impact a static magnetic field generated by permanent magnets on transcriptional activity NFE2L2 KEAP1 genes in human dermal fibrob...

PGRMC1 (progesterone receptor membrane component 1) is part of a multi-protein complex, that is highly expressed in several cancers and is involved in chemoresistance. Although PGRMC1 plays an important role in various cancers, little is known about how PGRMC1 expression is regulated. Therefore, the present study was designed to elucidate the molecular mechanisms that influence PGRMC1 expressio...

Osterix (Osx) is an osteoblast-specific transcription factor which is essential for bone formation. MicroRNAs (miRNAs) have been previously shown to be involved in osteogenesis. However, it is unclear whether Osx is involved in the regulation of miRNA expression. In this study, we have identified groups of miRNAs that are differentially expressed in calvaria of the E18.5 Osx(-/-) embryos compar...

Using an in vivo cycling strategy, we selected metastatic cancer cells from the lymph nodes (LN) of mice bearing orthotopic DU145 human prostate tumors. Repeated rounds of metastatic selection (LN1-LN4) progressively increased the epithelial phenotype, resulting in a new model of tumor cell mesenchymal-epithelial transition (MET). DU145-LN4 showed increased cell-cell adhesions, higher expressio...

Whereas miR-200 family is known to be involved in the epithelial-to-mesenchymal transition (EMT), a crucial biological process observed in normal and pathological contexts, it has been largely unclear how far the functional levels of these tiny RNAs alone can propagate the molecular events to accomplish this process within several days. By developing a potent inhibitor of miR-200 family members...

Human breast tumors contain a breast cancer stem cell (BCSC) population with properties reminiscent of normal stem cells. We found 37 microRNAs that were differentially expressed between human BCSCs and nontumorigenic cancer cells. Three clusters, miR-200c-141, miR-200b-200a-429, and miR-183-96-182 were downregulated in human BCSCs, normal human and murine mammary stem/progenitor cells, and emb...

To understand why livers from aged donors are successfully used for transplants, we looked for markers of liver aging in 71 biopsies from donors aged 12-92 years before transplants and in 11 biopsies after transplants with high donor-recipient age-mismatch. We also assessed liver function in 36 age-mismatched recipients. The major findings were the following: (i) miR-31-5p, miR-141-3p, and miR-...
