AIMS miR126-5p is processed from the miR126-3p/-5p duplex, which is expressed in endothelial cells and gives rise to the guide strand miR126-3p and the passenger strand miR126-5p. miR126-3p has prominent roles in vascular development and diseases, whereas the expression and physiological functions of miR126-5p are unknown. The purpose of this study was to evaluate the expression and role of miR...

Autophagy favors both cell survival and cancer suppression, and increasing evidence reveals that microRNAs (MIRs) regulate autophagy. Previously we reported that MIR126 is downregulated in malignant mesothelioma (MM). Therefore, we investigated the role of MIR126 in the regulation of cell metabolism and autophagy in MM models. We report that MIR126 induces autophagic flux in MM cells by downreg...

Angiogenesis, the process of new blood vessel formation, is an important therapeutic target in cardiovascular and malignant diseases for diverse reasons. Molecular imaging for angiogenesis has been attracted due to the use of anti-angiogenic therapeutic drugs to treat tumours, and of therapeutic angiogenesis induction to treat vascular diseases. We developed a novel biosensor of imaging microRN...

The protein known as Spred1 (Sprouty-related Ena/VASP homology-1 domain-containing protein) has been identified as a negative regulator of growth factor-induced ERK/mitogen-activated protein kinase activation. Spred1 has also been implicated as the target of microRNA-126 (miR126), a miRNA located within the Egfl7 gene, and is involved in the regulation of vessel development through its role in ...

BACKGROUND Mobilization of hematopoietic stem/progenitor cells from the bone marrow to the peripheral blood by granulocyte colony-stimulating factor is the primary means to acquire stem cell grafts for hematopoietic cell transplantation. Since hematopoietic stem/progenitor cells represent a minority of all blood cells mobilized by granulocyte colony-stimulating factor, the underlying mechanisms...

The vasculature of the central nervous system (CNS) is composed of vascular endothelial and mural cells which interact closely with glial cells and neurons. The development of the CNS vascularisation is a unique process which requires the contribution of specific regulators in addition to the classical angiogenic factors. The egfl7 gene is mainly detected in endothelial cells during physiologic...

The number of approved antiangiogenic drugs is constantly growing and emphasizes the need for predictive biomarkers. The aim of this study was to analyze the predictive value of epidermal growth factor-like domain 7 (EGFL7) and microRNA-126 (miR126) to first-line chemotherapy combined with bevacizumab, in patients with metastatic colorectal cancer (mCRC). A total of 158 patients from two differ...
