Stress neuropeptides in the human endometrium: Paracrine effects on cell differentiation and apoptosis

Achille Gravanis, Antonis Makrigiannakis, Ekaterini Chatzaki, Emmanuel Zoumakis, Christos Tsatsanis, Andrew N. Margioris

Human endometrium exhibits characteristics of a neuroendocrine-like stress organ in addition to its classical role as the main target of ovarian steroid hormones. Indeed, the epithelial cells of human endometrium express the stress-associated neuropeptide genes corticotropin-releasing hormone (CRH), proopiomelanocortin, proenkephalin and prodynorphin…

Insulin-like growth factor-1 restores dexamethasone-induced heart growth arrest in rats: the role of the ubiquitin pathway

OBJECTIVE: In skeletal muscle, glucocorticoids induce catabolism and proteolysis which is accomplished via the ubiquitin (Ub) proteolytic pathway. Cardiac muscle is a striated muscle which, compared to skeletal muscle, more abundantly expresses components of the Ub pathway, thus suggesting an important role for this pathway in heart physiology …

The role of iodine and δ-iodolactone in growth and apoptosis of malignant thyroid epithelial cells and breast cancer cells

OBJECTIVE: As we previously demonstrated, the inhibitory effect of iodine on thyroid cell growth is mediated by iodolactones, especially 6-iodo-5-hydroxy-eicosatrienoic acid (δ-iodolactone). In this communication we compare the effect of iodide, molecular iodine and δ-iodolactone on growth inhibition and apoptosis on three human thyroid carcinoma cell lines …
