Different neuroendocrine cell types in the pars intercerebralis of Periplaneta americana produce their own specific IGF-related peptides

Jan A. Veenstra

Summary: Among the nine genes related to insulin and insulin-like growth factor in the American cockroach, seven are expressed in the central nervous system. The cells in the pars intercerebralis show significant expression of five of these genes. Antisera testing confirms that these cells are neuroendocrine and project to the corpora cardiaca. In contrast to fruit flies, multiple cell types in cockroaches express different genes, indicating a more complex regulation by insulin and IGF-related peptides in cockroaches.

Genomic and transcriptomic analyses of the subterranean termite Reticulitermes speratus: Gene duplication facilitates social evolution

Shuji Shigenobu et al.

Summary: Termites are social organisms with a polyphenic caste system, and gene duplication plays a crucial role in their social evolution. The duplicated genes in the termite genome are associated with caste-biased gene expression and diverse social functions, contributing to caste-specialized functions. Gene duplication facilitates social evolution through regulatory diversification, leading to caste-biased expression and subfunctionalization and/or neofunctionalization.

Lifespan prolonging mechanisms and insulin upregulation without fat accumulation in long-lived reproductives of a higher termite

Sarah Seite et al.

Summary: The study reveals that the long lifespan of kings and queens in eusocial termites is associated with gene expression differences that reduce aging-related processes and enhance DNA damage repair and mitochondrial functions. Additionally, the downregulation of antioxidant gene expression and decrease in peroxidability of membranes contribute to the longevity. Surprisingly, an upregulation of components of the IIS pathway in fat bodies of reproductives, including insulin-like peptide Ilp9, does not lead to excessive fat storage in queens, suggesting a complex mechanism in maintaining their fertility.

Gonadulin: A newly discovered insulin-like peptide involved in ovulation and oviposition in Rhodnius prolixus, a vector of Chagas disease

Jimena Leyria et al.

Summary: Insulin-like peptides (ILPs) are crucial hormones found in all organisms, and a newly discovered ILP called gonadulin has been found to be highly expressed in the reproductive system of Rhodnius prolixus insects. In this study, it was observed that impairment of the gonadulin signaling cascade inhibited ovulation and oviposition, leading to egg retention. Understanding the reproductive processes in R. prolixus could provide insights for the development of biopesticides to control insect populations and disease transmission.

Insulin signaling in the long-lived reproductive caste of ants

Hua Yan et al.

Summary: Reproduction is correlated with shorter life span in most organisms. However, in Harpegnathos ants, workers can switch to reproductive pseudo-queens and exhibit a prolonged life span. Increased insulin expression in the gamergate brain leads to increased lipid synthesis and vitellogenin production in the fat body, extending their longevity. The anti-insulin Imp-L2 in the gamergate developing ovary decreases signaling in the fat body, consistent with their extended life span.

Experience-expectant brain plasticity corresponds to caste-specific abiotic challenges in dampwood termites (Zootermopsis angusticollis and Z. nevadensis)

Sean O'Donnell et al.

Summary: This study found that in dampwood termites, winged primary reproductives (Kings/Queens) have relatively larger visual processing brain regions (optic lobes) compared to other castes. This suggests that the size of the optic lobes is related to the caste's exposure to complex visual environments.

Progress in the characterization of insulin-like peptides in aphids: Immunohistochemical mapping of ILP4

Paolo Cuti et al.

Summary: Aphids undergo a seasonal switch from viviparous parthenogenesis to sexual reproduction in response to changing photoperiods, possibly mediated by two insulin-like peptides (ILP1 and ILP4). ILP4 is synthesized in specific neurosecretory cells in the aphid brain and transported to the corpora cardiaca and abdomen, suggesting a direct connection between neurosecretory cells and the reproductive system. Additionally, collateral arborizations from the neurosecretory cells to areas containing clock neurons and photoreceptors hint at a possible communication between circadian and photoperiodic systems.

Ambulacrarian insulin-related peptides and their putative receptors suggest how insulin and similar peptides may have evolved from insulin-like growth factor

Jan A. Veenstra

Summary: The study identified a triplet of genes encoding irps in some ambulacrarians, with two being orthologs of arthropod genes. In echinoderms, two new irps emerged from gene duplications, likely from IGF and dilp7-like genes. This suggests that irps produced by neuroendocrine cells in insects and echinoderm GSS may have evolved independently from IGF, indicating convergent evolution.

Identification of Gonadulin and Insulin-Like Growth Factor From Migratory Locusts and Their Importance in Reproduction in Locusta migratoria

Jan A. Veenstra et al.

Summary: Several genes related to insulin have been identified in the migratory locust, including gonadulin and aIGF. These genes are expressed in various tissues, with gonadulin specifically expressed in the ovary and its receptor transcript abundantly expressed in the ovary, fat body, and central nervous system. The central nervous system-fat body-ovary axis plays a crucial role in reproduction, indicating the important role of gonadulin in regulating vitellogenesis and oocyte growth.
