Many marine sponges have been shown to produce metabolites with cell growth and endocrine altering activities. We tested crude extracts (1.0 mg/ml) from two species (AV and SB) for effects on levels of an important cell cycle regulatory protein, cyclin B1; cell cycle growth-phase (sub-G1/Apoptosis, G1, S, and G2/M), as well as on cell survival in SW-13 human adrenal carcinoma cultures. Polyacrylamide gel electrophoresis studies of cyclin B1 levels indicate a 60-90 % reduction ...

Up to now there are few studies about differential proteomics in thyroid. Our group has developed a method for standard human primary thyroid culture maintaining the phenotype through passages. Thus, we believe of great interest the search for biomarkers in these cultures by 2D-PAGE coupled to MALDI-TOF/TOF-MS.Aims: i) To standardize the conditions for sample extraction and controls. ii) To compare and identify the differential proteomic pattern between ...

Background: Vitamin D deficiency is common worldwide. No homogenous reference values have yet been established and no studies of values have been done in Spain involving a large number of participants.Objective: To study the population concentrations of vitamin D in a representative sample of the Spanish population.Subjects/methods: The study involved two cohorts from Spain, the Asturias Study and the Pizarra Study, which are two p...

Somatostatin (SST), Cortistatin (CORT), Neuronostatin (NST) and their receptors [SST/CORT-receptors (sst1–5/sst5TMD4-TMD5) and NST-receptor (GPR107)] comprise a hormonal pleiotropic system involved in the regulation of multiple pathophysiological functions. Certain components of this system are dysregulated in endocrine-related cancers, including prostate cancer (PCa), wherein we have found that alterations in specific components of this regulatory system [i.e. NST-GPR10...
