"Responses of Python Gastrointestinal Regulatory Peptides to Feeding" (2001)
- Hormone and peptide levels are elevated after feeding.
- Organ morphology begins changing even before food hits the organ.
"Adaptive Regulation of Digestive Performance in the Genus Python" (2007)
- The post-prandial growth of the Small Intestine is attributed to hypertrophy rather than hyperplasia.
- Intracellular stores of protein contribute to increased intestinal mass and nutrient up-take.
- Lipid droplets from the meal also increase intestinal mass.
Questions to Consider:
- Do new proteins replace the intracellular stores of protein when stored proteins travel to the cell surface?
- Are cell division and apoptosis up-regulated?
Remember: we are only working with RNA.
- Use Unix to download FastQC data analysis results.
