Article Discussion
"Adaptive Responses to Feeding in Burmese Pythons: Pay Before Pumping" (1995)
- Small Intestine mass doubled and other organ masses also increased 1-3 days post-feeding.
- Post-feeding effects also includes upregulation of intestinal uptake transporters and hydrolytic enzymes.
- The mucosal layer of the small intestine experiences greater increase in mass as compared to the serosa.
"A Vertebrate Model of Extreme Physiological Regulation" (1998)
- Snake post-prandial responses are adaptive rather than phylogenetic.
- We need to investigate the sglt-1 gene.
Questions to Consider:
- Transport Mechanism:
- Is there an increase in transcription?
- Is there a hormonal response?
- Are there post-translational modifications?
- Can we find an ortholog and trace it back to the Burmese Python?
- Can we find intestinal genes involved in housekeeping, cell-proliferation, or up-take?
- How will our results be affected if we only sampled serosa from the Small Intestine?
- How does the brush-border get bigger?
