Mutual catalytic effects within the Salt-Induced Peptide Formation (SIPF) Reaction might be one little puzzle piece in the complicated process of the formation of complex peptidic systems and their chemical evolution on the prebiotic earth. The catalytic effects of glycine and diglycine on the formation of dipeptides from mixed amino acid systems in the(More)
Although the mechanisms regulating pituitary tumor development and progression are still unclear, new information on the molecular mechanisms involved in the pathogenesis of human pituitary tumors have accumulated. Recent evidence suggests that galectin-3 plays an important role in pituitary tumorigenesis and in tumor progression. Galectin-3 is expressed in(More)
The rather unique properties of prions and their presence in very different kinds of living species suggest that this type of molecule was created at a very early stage of evolution and may even represent a relic from a time where peptide evolution was ongoing and RNA/DNA did not yet exist. A comparison of the most frequently occurring amino acid sequences(More)
