dc.description.abstract | Allatoregulatory neuropeptides are multifunctional proteins that take part in the synthesis
and secretion of juvenile hormones. In insects, allatostatins are inhibitors of juvenile hormone
biosynthesis in the corpora allata while allatotropins, act as stimulators. By quantitative
real-time PCR, we analyzed the gene expression of allatostatin A (PtASTA), allatostatin
B (PtASTB), allatostatin C (PtASTC), allatotropin (PtAT) and their receptors (PtASTA-R,
PtASTB-R, PtASTC-R, PtAT-R) in various tissues in different age groups of female spiders.
In the presented manuscript, the presence of allatostatin A, allatostatin C, and allatotropin
are reported in females of the spider P. tepidariorum. The obtained results indicated substantial
differences in gene expression levels for allatoregulatory neuropeptides and their
receptors in the different tissues. Additionally, the gene expression levels also varied
depending on the female age. Strong expression was observed coinciding with sexual maturation
in the neuroendocrine and nervous system, and to a lower extent in the digestive tissues
and ovaries. Reverse trends were observed for the expression of genes encoding the
receptors of these neuropeptides. In conclusion, our study is the first hint that the site of synthesis
and secretion is fulfilled by similar structures as observed in other arthropods. In addition,
the results of the analysis of spider physiology give evidence that the general functions
like regulation of the juvenile hormone synthesis, regulation of the digestive tract and ovaries
action, control of vitellogenesis process by the neuropeptides seem to be conserved among
arthropods and are the milestone to future functional studies. | pl_PL |
