Since the work of Greenspan in 1976 4 , several approaches have been developed to model tumour growth 5 , continuum models at the tissue scale 6 , discrete models at the cell scale 7,8 and hybrid continuum-discrete models 9
Key Advantages of Peptide Pills Non-invasive Eliminates the need for injections Patient-friendly Easier administration for chronic treatments Targeted action Can treat GI diseases without entering the bloodstream Testing Peptide Pills in Mice As a proof of concept, the researchers tested their new enzyme-resistant peptides in mice
yet, remarkably, mice with TR/GR-null livers thrive, in part by synthesizing life-sustaining cysteine through alternative pathways that evolved in metazoans
However, 15% to 20% of ER+ tumors are intrinsically resistant to endocrine treatment while 30% to 40% of ER+ tumors develop endocrine resistance to this class of drugs throughout treatment [9, 10]
