Formation of vessels requires "epithelial-mesenchymal" transition of endothelial cells, with several modifications at the level of endothelial cell plasma membranes. These processes are associated with redistribution of cell-cell and cell-substrate adhesion molecules, cross talk between external ECM and internal cytoskeleton through focal adhesion molecules and the expression of several proteol...

Colorectal cancer stands at the top of oncologic pathology in the world, and in the same measure in Romania because is the third most frequent cancer diagnosed in men and women. Colorectal cancer develops as a result of mutations in genes that control proliferation and cell death. It was established that in the development of a tumor there is originally a prevascular phase followed by a phase o...

BACKGROUND We have previously shown, using the chicken embryo chorioallantoic membrane (CAM) model of in vivo angiogenesis, that X-rays act on the extracellular matrix and enhance normal and tumor-induced angiogenesis. In the present work, we studied the effect of X-rays on the gene expression of three proteins that are important regulators of angiogenesis: vascular endothelial growth factor (V...

Previous studies have demonstrated that Smyd1 plays a critical role in cardiomyocyte differentiation, cardiac morphogenesis and myofibril organization. In this study, we uncovered a novel function of Smyd1 in the regulation of endothelial cells (ECs). Our data showed that Smyd1 is expressed in vascular endothelial cells, and knockdown of SMYD1 in endothelial cells impairs EC migration and tube ...

Angiogenesis is the process by which new blood vessels are formed. This process supports normal physiology as well as contributes to progression of disease. Progressive rheumatoid arthritis and growth of tumors are two pathologies to which angiogenesis contributes. In arthritis, we know that prostaglandins (PGs) and the enzyme cyclooxygenase-2, which catalyses prostaglandin production, are infl...

We have earlier shown that dystroglycan (DG) is a lamininbinding protein and as such is a cell adhesion molecule. DG is a heterodimer of alpha and beta DG subunits. beta-dystroglycan (betaDG) is the membrane spanning subunit, whereas the alpha subunit is bound to the extracellular domain of betaDG. To study physiological function of the protein, we expressed full-length DG (FL-DG) and the cytop...

background: angiogenesis, the formation of new blood vessels from preexisting ones, is one of the most important physiological and pathological processes occur in the body. in the pathological conditions such as tumor growth, psoriasis, corneal neovascularization and rheumatoid arthritis, angiogenesis is crucially required for the devolopment of the disease. zataria multiflora as a member of la...

Abstract Receptor‐type protein tyrosine phosphatases (RPTPs), Class I phosphatases, are involved in human tumor cell proliferation, apoptosis, migration, and invasion through reversible phosphorylation of residues. This review summarizes the expression role RPTPs cancer illustrates signaling pathway mechanisms effecting oncogenesis, progression, prognosis, angiogenesis, so as to provide more ef...

In appendiceal cancers, the most frequently mutated genes are (i) KRAS, which, when reactivated, restores signal transduction via RAS–RAF–MEK–ERK signaling pathway and stimulates cell proliferation in early stages of tumor transformation, then angiogenesis; (ii) TP53, whose inactivation leads to inhibition programmed death; (iii) GNAS, links cAMP pathway, stimulating (iv) SMAD4, exhibiting typi...
