[Transcriptome alteration in hippocampus under the treatment of tuftsin analog Selank]
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
In this rat study, the authors used cDNA microarray technology to examine the effect of single and course administration of Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) at 200 microg/kg on the hippocampal transcriptional profile. The abstract reports that mRNA levels of 36 genes changed more than 2-fold after a single intranasal Selank administration and 20 genes after course administration, and that most encode plasma-membrane-associated proteins including transmembrane proteins. The authors suggest Selank may regulate ion homeostasis of hippocampal cells and thereby modulate ion-dependent processes including learning and memory formation.
Abstract
The effect of single and course administration of Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) in the dose 200 microg/kg on the rat hippocampus transcriptional profile were studied using cDNA microarray technology. It was shown that mRNA levels of 36 genes changed more than 2-fold after a single intranasal Selank administration, and 20 genes--after course administration. It should be noted that most of them encode proteins associated with the plasma membrane (including transmembrane proteins). This suggests that Selank is able to regulate ion homeostasis of hippocampal cells and thereby modulate different ion-dependent processes, which include the processes of learning and memory formation.
