生物活性

Biotin-Substance P is the biotin tagged Substance P. Substance P (Neurokinin P) is a neuropeptide, acting as a neurotransmitter and as a neuromodulator in the CNS. The endogenous receptor for substance P is neurokinin 1 receptor (NK1-receptor, NK1R)[1].

体外研究
(In Vitro)

The neuropeptide substance P (SP) that are mediated by the neurokinin 1 receptor (NK1-R) desensitize and resensitize, which may be associated with NK1-R endocytosis and recycling. SP and the NK1-R are internalized into the same clathrin immunoreactive vesicles, and then sorted into different compartments. SP is intact at the cell surface and in early endosomes, but slowly degraded in perinuclear vesicles. SP induces clathrin-dependent internalization of the NK1-R. The SP/NK1-R complex dissociates in acidified endosomes. SP is degraded, whereas the NK1-R recycles to the cell surface. SP induces internalization of the NK1-R both in transfected epithelial cells[1].

Substance P (7-11) increases PGE2 and collagenase production at concentrations greater than 1 μM. Substance P (7-11), but not intact SP, SP-(1-4), SP-(1-6), SP- (8-11) or SP-(9-1 1), nor the tachykinins NKA and NKB, causes an increase in the intracellular calcium concentration as measured by the fluorescent dye Fura-2. The maximal change in intracellular calcium induced by 10 μM Substance P (7-11) was 140±30 nM[1].

Cell Assay
[1]

Confluent chondrocytes are incubated for 24 h with SP or Substance P (7-11). TIMP activity is inactivated following reduction and alkylation with 2 mM dithiothreitol and 5 mM iodoacetamide for 30 min at 37°C. Samples are subsequently dialysed. Latent collagenase is activated with 1 mM APt followed by inactivation with soy bean trypsin inhibitor. Collagenase is measured[1].

Substance P(1-7) TFA is a fragment of the neuropeptide, substance P (SP). Substance P(1-7) TFA gives depressor and bradycardic effects when applied to the nucleus tractus solitarius[1].

体内研究
(In Vivo)

Substance P(1-7) is found to act as a very potent antagonist against the SP-induced responses and is formed locally in the nigra after SP injection. It is proposed that Substance P(1-7) is an endogenous modulator of SP actions[1]. Injection of low doses of Substance P(1-7) (1.0-4.0 pM simultaneously with SP or SP(5-11) (0.1 nM), reduce aversive behaviours induced by SP or SP(5- 11) significantly. These results indicate that SP(1-7) formed endogenously could modulate the actions of SP or SP(5-11) in the spinal cord[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[1][2]

Rats[1]

Sprague-Dawley male rats weighing 250-300 g are anaesthetized with halothane and placed in a stereotaxic frame. An injection cannula, conically shaped with a penetration tip diameter of approximately 0.15 mm is loared into the SNR. Saline (0.2 μL), SP (0.007-0.7 nmol) or Substance P(1-7) (0.01-1 nmol) is injected into the left substantia nigra, pars reticulata (SNR) and the rat is placed in a rotometer. The substances are injected in a total volume of 0.2 μL over a period of 1 min. A group of animals is sacrificed by decapitation 1 hour after the injection, their brains are immediately removed and tissue samples are taken from left and right striatum, globus pallidum (GP) and substantia nigra (SN). Samples are assayed for SP and SP(1-7)[1].
Mice[2]
The accumulated response time (s) of reciprocal movements of hindlimb scratching, biting, fore- and hindpaw licking are measured in Male mice (STD strain, 23-28 g) during the whole period of aversive response and 20 min at maximum. Substance P(1-7) is tested for its ability to inhibit the aversive response produced by intrathecal injection of SP or SP(5-11) (0.1 nM/mouse). Substance P (1-7) (1, 2, 4 pmol) is then administered together with SP or SP(5-11)[2].
