Enhanced expression of neurotensin/neuromedin N mRNA and products of NT/NMN precursor processing in neonatal rats
K Muraki, SP Mitra, PR Dobner, RE Carraway - Peptides, 1993 - Elsevier
Intestinal levels of immunoreactive neurotensin (iNT) and neuromedin N (iNMN), as well as
mRNA for the NT/NMN precursor, were elevated during the suckling period in rats. While
transient expression of NT/NMN was observed at 1–5 days of age in the proximal small
intestine and colon, NT/NMN levels in the ileum increased to peak at 10–20 days of age and
then decreased to adult levels. The levels of these peptides were not elevated in the central
nervous system and pituitary over this time period. Chromatographic analyses of jejunoileal …
