Summary
This summary is machine-generated.Vascular endothelial growth factor (VEGF) is highly expressed in adrenal cortical carcinoma (ACC) but not in normal adrenal tissue. Endocan is elevated in both adrenal tumors and normal tissue, with higher expression in ACC.
Area Of Science
- Endocrinology
- Oncology
- Molecular Biology
Background
- Adrenal cortical tumors encompass adenomas (ACA) and carcinomas (ACC).
- Vascular endothelial growth factor (VEGF) and endocan are implicated in tumor angiogenesis and progression.
- Understanding their expression patterns in adrenal tumors is crucial for diagnosis and treatment.
Purpose Of The Study
- To investigate the tissue expression of VEGF and endocan in adrenal cortical tumors.
- To correlate VEGF and endocan expression with tumor type (ACA vs. ACC) and normal adrenal tissue.
Main Methods
- Immunohistochemical analysis of VEGF and endocan expression in adrenal tissues.
- Quantification of positive staining cells on a scale from negative to strongly positive.
- Comparison of expression levels between ACA, ACC, and normal adrenal cortex groups.
Main Results
- VEGF was detected in 16.7% of ACA, 85.7% of ACC, and 0% of normal adrenal tissues.
- Endocan was detected in 100% of ACA, 100% of ACC, and 30.7% of normal adrenal tissues.
- Endocan expression intensity was significantly higher in ACC compared to ACA and normal tissues.
Conclusions
- VEGF expression is a potential biomarker distinguishing ACC from ACA and normal adrenal tissue.
- Endocan is upregulated in adrenal cortical tumors, with significantly higher levels in ACC.
- Combined analysis of VEGF and endocan may aid in the differential diagnosis of adrenal cortical lesions.

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
