Our group focuses on different areas of research.
Erectile dysfunction: Endothelial dysfunction is one of the first symptoms of erectile dysfunction (ED) and is closely related to atherosclerosis and risk factors such as diabetes mellitus (DM), both characterised by an advanced inflammatory and oxidative state. Vardenafil is one of the most effective 5-phosphodiesterase inhibitors in patients with ED and DM. We have determined the plasma proteome of DM patients and the effect of vardenafil administration on the expression of proteins related to inflammatory oxidative stress and cellular homeostasis. We have observed a significant negative correlation between plasma levels of beta-tropomyosin and the IIEF-EFI index. Elevated plasma beta-tropomyosin levels indicate cell damage and loss of cell regenerative capacity.
Urothelial cancer: Exosomes are extracellular vesicles that act as potent intercellular mediators containing membrane proteins and cytosolic, specific mRNAs and miRNAs, and that can be obtained from fluids such as urine. We have analysed the content of miRNA and urinary exosome proteins in order to find diagnostic markers for urothelial bladder cancer. Some of these miRNAs are involved in tumour cell proliferation, inhibition of tumour suppressor genes, activation of EMT and metastatic status, are significantly reduced in the urinary exosomes of patients with urothelial bladder carcinomas and may be useful as non-invasive diagnostic biomarkers in bladder cancer.
Regarding diagnostic techniques, we have optimised the endourological, therapeutic and diagnostic approach for urothelial cancer of the upper tract.
