Peptides and epithelial growth regulationle some of these may act directly, many may be involved in regulating the powerful trophic effects of the intake and digestion of food on the gut epithelium. — Several peptides have been associated with the regulation of intestinal cell proliferation. There is little doubt that gastrin is trophic toInfantry 发表于 2025-3-25 11:22:28

Transgenic mouse models and peptide producing endocrine tumours: morpho-functional aspectsof the transforming oncoprotein simian virus 40 (SV40) large T-antigen. The SV40/metallothionein-growthh hormone (MGH), the insulin/ SV40 (INS/SV40) and the vasopressin/SV40 (AVP/SV40) transgenic mice models all developed endocrine tumours of pancreas mainly composed of insulin-producing B cells, wi宣传 发表于 2025-3-25 18:03:00

Regulatory peptides in the respiratory systemted peptide) are localised to neuroendocrine cells and may have a trophic or transmitter rôle. Others are localised to motor nerves. Vasoactive intestinal peptide and peptide histidine isoleucine are candidates for neurotransmitters of non-adrenergic inhibitory fibres and may be co-transmitters in c不合 发表于 2025-3-26 12:59:00
