Summary of "Significantly different expression levels of microRNAs associated with vascular invasion in hepatocellular carcinoma and their prognostic significance after surgical resection."

Although gross vascular invasion (VI) has prognostic significance in patients with hepatocellular carcinoma (HCC) who have undergone hepatic resection, few studies have investigated the relationship between gross VI and aberrant expression of microribonucleic acids (miRNAs and miRs). Thus, the objective of this study was to identify miRNAs selectively expressed in HCC with gross VI and investigate their prognostic significance.

Medical and Biotech [MESH] Definitions

A vascular endothelial cell growth factor receptor whose expression is restricted primarily to adult lymphatic endothelium. VEGFR-3 preferentially binds the vascular endothelial growth factor C and vascular endothelial growth factor D and may be involved in the control of lymphangiogenesis.

A vascular endothelial growth factor whose expression is found largely restricted to the GONADS; ADRENAL CORTEX; and PLACENTA. It has similar biological activity to VASCULAR ENDOTHELIAL GROWTH FACTOR-A.

The original member of the family of endothelial cell growth factors referred to as VASCULAR ENDOTHELIAL GROWTH FACTORS. Vascular endothelial growth factor-A was originally isolated from tumor cells and referred to as "tumor angiogenesis factor" and "vascular permeability factor". Although expressed at high levels in certain tumor-derived cells it is produced by a wide variety of cell types. In addition to stimulating vascular growth and vascular permeability it may play a role in stimulating VASODILATION via NITRIC OXIDE-dependent pathways. Alternative splicing of the mRNA for vascular endothelial growth factor A results in several isoforms of the protein being produced.

A TALE-type homeodomain protein and transcription factor that functions as a regulator of PAX6 PROTEIN expression and as an activator of PLATELET FACTOR 4 gene expression. It is essential for hematopoiesis, differentiation of MEGAKARYOCYTES, and vascular patterning. It may also have a role in the induction of myeloid leukemias.

Extracellular membrane vesicles generated by the shedding of CELL MEMBRANES blebs. Microparticles originating from PLATELETS; ENDOTHELIAL CELLS; and other cell types circulate in the peripheral blood and through the MICROVASCULATURE where larger cells cannot, functioning as active effectors in a variety of vascular processes such as INFLAMMATION; HEMOSTASIS; angiogenesis; and vascular reactivity. Increased levels are found following stimulation of bleb formation under normal or pathological conditions.
