生物活性

Neuronostatin-13 human is a 13-amino acid peptide hormone encoded by the somatostatin gene and plays an important role in the regulation of hormonal and cardiac function.

体外研究
(In Vitro)

Neuronostatin-13 human is a 13-amino acid peptide hormone encoded by the somatostatin gene and plays an important role in the regulation of hormonal and cardiac function. Treatment with Neuronostatin-13 human (1,000 nM) enhances low-glucose-induced glucagon release compare with islets treated with control medium alone. Treatment with Neuronostatin-13 human for 1 h leads to a significant increase in the accumulation of glucagon mRNA compare with vehicle-treated control cells. In αTC1-9 α-cells, treatment with 100 nM Neuronostatin-13 human leads to an increase in phosphorylated PKA at 30 and 40 min[1].

体内研究
(In Vivo)

Infusion with Neuronostatin-13 human delays glucose clearance in the rat model, such that blood glucose levels in Neuronostatin-13 human-treated animals are significantly higher at 1 and 10 min following intra-arterial injection of a glucose bolus[1]. Chocardiographic measurement reveals a remarkable drop in heart rate after 3-, 6- and 12-hr of Neuronostatin-13 human challenge. In addition, Neuronostatin-13 human treatment significantly decreases left ventricular end-systolic diameter (LVESD) and fractional shortening without affecting left ventricular end-diastolic diameter (LVEDD) between 6 and 12 hrs following Neuronostatin-13 human challenge, the effect of which returns to basal level 18-hr after Neuronostatin-13 human treatment[2].

Peptide Solubility and Storage Guidelines:

1.;;Calculate the length of the peptide.

2.;;Calculate the overall charge of the entire peptide according to the following table:

; Contents Assign value
Acidic amino acid Asp (D), Glu (E), and the C-terminal -COOH. -1
Basic amino acid Arg (R), Lys (K), His (H), and the N-terminal -NH2 +1
Neutral amino acid Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q) 0

3.;;Recommended solution:

Overall charge of peptide Details
Negative (lt;0) 1.;;Try to dissolve the peptide in water first.
2.;;If water fails, add NH4OH (lt;50 μL).
3.;;If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (gt;0) 1.;;Try to dissolve the peptide in water first.
2.;;If water fails, try dissolving the peptide in a 10%-30% acetic acid solution.
3.;;If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO.
Zero (=0) 1.;;Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first.
2.;;For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration.

Cell Assay
[1]

For studies examining hormone secretion from cell lines, INS 832/13 or αTC1-9 cells are plated in 96- or 24-well plates at a density of 0.25×105 cells/well or 1.0×105 cells/well in complete medium. The day of the experiment, cells are washed in PBS and allowed to preincubate in low- or high-glucose KRB buffer for 1 h in the presence or absence of Neuronostatin-13 human. Hormone secretion is performed using a 2-h static incubation. Supernatants are collected, and insulin or glucagon content is determined[1].

Animal Administration
[2]

3-month-old adult male C57BL/6 mice are used and housed in a temperature-controlled environment (22.8±2.0°C, 45 to 50% humidity) with a 12:12h light/dark cycle with free access to food and tap water. For Neuronostatin-13 human challenge in vivo, 3-month-old adult C57BL/6 male mice are randomly divided into two groups and to receive Neuronostatin-13 human (50 μg/kg, i.p.). Cardiac function is evaluated at 3-, 6-, 12- and 18-hr after Neuronostatin-13 human treatment in the first group of animals[2].
