Product Description
Neurotensin is an intestinal tridepeptide that works as a potent cell mitogen in a variety of colorectal and pancreatic cancers and has high affinity for neurotensin receptor (NTR).
Biological Activity I Assay Protocols (From Reference)
ln Vitro
Neurotensin promotes the release of IL-8 in an untransformed colon epithelial cell line stably transfected with NTR and induces the expression of MIP-2, MCP-1, IL-1β, and TNFα in animal microglia. The majority of human pancreatic and colorectal malignancies include high-affinity NTRs, which belong to the G protein-coupled receptor (GPCR) family and imply that neurotensin (NT) may have an endocrine effect on tumor growth. Numerous signal transduction pathways, including as intracellular calcium ([Ca2+]i), mitogen-activated protein kinase (MAPK), ERK and JNK, and different PKC isoforms, are known to be stimulated by neurotensin through NTR1. Neurotensin therapy (100 nM) significantly boosted HCT116 cell migration (about three times) as compared to vehicle treatment; pretreatment with curcumin (10 μM) inhibited the stimulating effect of NT on HCT116 cell migration. The proliferative effects of neurotensin are partly attributed to NT stimulation of MEK/ERK and regulation of downstream AP-1 transcription factors [1].

Additional Infomation
Neurotensin is a 13 amino acid peptide hormone which is found in the central nervous system and the gastrointestinal tract. It behaves as a neurotransmitter in the brain, as a hormone in the gut, and also as a neuromodulator. It is implicated in the pathophysiology of several CNS disorders (including schizophrenia, Parkinson's disease, drug abuse, pain, cancer, inflammation, eating disorders and central control of blood pressure) due to its association with a wide variety of neurotransmitter systems such as dopaminergic, sertonergic, glutamatergic, GABAergic, and cholinergic systems. It has a role as a human metabolite, a mitogen, a neurotransmitter and a vulnerary. It is a conjugate base of a neurotensin(1+).
A biologically active tridecapeptide isolated from the hypothalamus. It has been shown to induce hypotension in the rat, to stimulate contraction of guinea pig ileum and rat uterus, and to cause relaxation of rat duodenum. There is also evidence that it acts as both a peripheral and a central nervous system neurotransmitter.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
