Description

Gap 27, connexin43 mimetic peptide, is a gap junction inhibitor.

In Vitro

Gap 27 causes a remarked decrease in the number of both TRAP-positive mononuclear and multinucleated rat osteoclasts cultured on bovine bone slices. The activity of the remaining osteoclasts is found to be diminished by measuring the percentage of osteoclasts with actin rings of all TRAP-positive cells. In addition, the resorbed area in the treated cultures is greatly diminished[1]. Incubation of the carotid artery with the gap junction inhibitor Gap 27 (500 μM) essentially abolishes the hyperpolarization to acetylcholine but it is without effect on that to levcromakalim. In the guinea-pig isolated internal carotid artery, Gap 27 inhibits acetylcholine-induced, endothelium-dependent hyperpolarizations[2].

In Vivo

Gap 27 (300 μM) inhibits relaxation by 40% in thoracic aorta and the superior mesenteric artery. Gap 27 also attenuates the endothelium-dependent component of the relaxation induced by ATP in thoracic aorta. [3].

Cell Assay
[1]

Bone cell cultures are cultured for 48 hours with three different treatments (control, heptanol and Gap 27). After the culture period, bone slices are fixed. The cells are stained for tartrate-resistant acid phosphatase (TRAP). To visualise the nuclei, the cells are incubated with the DNA-binding fluorochrome Hoechst 33258 (1 mg/mL stock diluted 1:800 in PBS) for 10 minutes at room temperature. The numbers of mononuclear and multinucleated TRAP-positive cells on each bone slice are counted[1].

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