Although pentagastrin has a tropic action on intestinal mucosa in suckling rat pups, and at weaning a rise in gastrin levels coincides with maturation of the intestinal mucosa, direct correlations of serum gastrin levels and intestinal maturation have yet to be made. Ten-day-old rats were subjected either to antrectomy to produce a 43% decrease in serum gastrin levels or to fundectomy to produce a 319% increase over gastrin levels in rumenectomized or normal animals. These changes were not associated with tropic or adaptive changes in jejunal or colonic mucosa as determined by jejunal and colonic DNA content, jejunal sucrase activity, jejunal villous height, or crypt depths in jejunum and colon at the beginning (day 15), middle (day 21), or end (day 27) of the weaning period. To the contrary, an inverse relation was found between serum gastrin levels and both jejunal mucosal DNA content and sucrase activity as an index of maturation.

Objective: Urinary proteins are effective tumor biomarkers. Human epididymis protein 4 (HE4), progastrin-releasing peptide (ProGRP), carcinoembryonic antigen (CEA), cytokeratin-19 fragment 21-1(CYFRA 21-1), and neuron-specific enolase (NSE) in serum, were proposed as tumor biomarkers of lung cancer. Our aim was to identify the urine protein biomarkers that can distinguish patients with lung cancer from healthy individuals and/or patients with benign lung disease with a high level of sensitivity and specificity.
