The opportunity to study the effects of prolonged fasting is rare. In this study we recorded anthropometric, biochemical and endocrine changes during the refeeding period following a 44 day fast, and compared them with results from 16 age-, sex- and body mass index (BMI)-matched controls.The index subject took only water to drink during the fast. He lost 24.5kg changing his BMI from 29 to 21.6. He underwent careful slow refeeding for the first 4 days usi...

It has been reported that Ang II induces the growth of MCF-7 breast cancer cells (Muscella et al., J Endocrinol 173, 315-323, 2002). Here we have examined the signalling pathways evoked by Ang II in MCF-7. Ang II did not change the concentration of intracellular calcium but induced the cytosol-to-membrane translocation of atypical protein kinase C zeta (PKC-zeta). Ang II dose-dependently induced c-fos (mRNA and protein) and enhanced the phosphorylation state of extracellular s...
