Regulatory Peptides (2001)

*lots of hormones and peptides
*intestine changes before the meal reaches it
*we hypothesize that active eating activates hormone response; looking early on, hours after eating
*enzymes need to make the hormones and then we need the receptors
*plasma membrane or cytoplasm
*some of the mammalian antibodies cross react - no the intended target
*used column chromatography to try to identify reptilian versions of synthetically produced human homologs

Adaptive Regulation (2007)

*Fig 1. ever letter is sig. dif. from other letters
*change in intestine mass is from hypertrophy - cells grow bigger, not replication
*cell division increased, but so did apoptosis
*enterocytes increase volume
*transport proteins may already exist in intracellular membranes that are then released to the luminal membrane
*would not result in a peak in RNA transcription
*part of why the cells are fatter is because they cells are full of lipid droplets
*endocytosis - not actively transported
