Neurotensin 是一种 13 个氨基酸的神经肽，参与调节促黄体激素和催乳素的释放，并与多巴胺能系统有显着的相互作用。它作为细胞有丝分裂原，作用于各种结肠直肠癌和胰腺癌。

Neurotensin is a 13 amino acid neuropeptide that is implicated in the regulation of luteinizing hormone and prolactin release and has significant interaction with the dopaminergic system.

Neurotensin induces the expression of MIP-2, MCP-1, IL-1β and TNFα in murine microglial cells and stimulates IL-8 secretion in a non-transformed colon epithelial cell line stably transfected with the NTR. The high-affinity NTR is a member of the G-protein coupled receptor (GPCR) family that is present in a majority of human pancreatic and colorectal cancers. It suggests that Neurotensin (NT) may act in an endocrine fashion to affect tumor growth. Acting through the NTR1, Neurotensin is known to stimulate various signal transduction pathways, including intracellular calcium ([Ca2+]i), the mitogen-activated protein kinases (MAPKs), ERK and JNK, and various PKC isoforms. Treatment of HCT116 cells with Neurotensin (100 nM) significantly increases HCT116 cell migration (~3-fold) compared with vehicle treatment; pretreatment with Curcumin (10 μM) blocksthe stimulatory effect of NT on HCT116 cell migration. ctivation of MEK/ERK by NT and downstream induction of AP-1 transcription factors contributes to the proliferative effects of Neurotensin[1].
