Abstract

Since the early days of cloning the first adipokinetic hormone (AKH) gene, researchers recognized that this gene also codes for a joining region and for a second peptide called adipokinetic hormone precursor related peptide (APRP). In species with more than one AKH gene, such as locusts, APRPs can form both homodimers and heterodimers. Database analysis showed that APRPs might belong to the ancient family of growth hormone releasing factor but they still are functionally orphan. We investigated whether some of the APRP forms play a role in control of reproduction or/and growth via stimulation of ecdysteroidogenesis.

Edible insect Locusta migratoria shows intestinal protein digestibility and improves plasma and hepatic lipid metabolism in male rats

Masaru Ochiai, Kou Tezuka, Haruka Yoshida, Takashi Akazawa, Yusuke Komiya, Hideki Ogasawara, Yuto Adachi, Minori Nakada

Summary: This study clarified the amino acid value, protein digestibility, and dietary effects of edible migratory locust powder (MLP) on growth and lipid metabolism in rats. The results showed that dietary MLP had favorable effects on growth, intestinal condition, and lipid metabolism in rats, especially on low-density lipoprotein metabolism and arteriosclerosis-related fatty acids.

Novel grasshopper protein/soy protein isolate/pullulan ternary blend with hesperidin derivative for antimicrobial edible film

Zisen Zhang, Changqing Fang, Wei Zhang, Wanqing Lei, Dong Wang, Xing Zhou

Summary: In this study, a new ternary blend composites were formed by mixing edible grasshopper protein and soybean protein isolates with the addition of pullulan. The effect of incorporating methyl hesperidin as an antimicrobial agent was investigated. The results showed that the addition of pullulan greatly improved the tensile strength of the protein blend composites, with 5% methyl hesperidin further enhancing it without negative impact on elongation at break. The compatibility between pullulan and protein blend was confirmed by SEM and XRD results, and the hydrophobicity of the composites slightly increased.

Entomotherapeutic Role of Periplaneta americana Extract in Alleviating Aluminum Oxide Nanoparticles-Induced Testicular Oxidative Impairment in Migratory Locusts (Locusta migratoria) as an Ecotoxicological Model

Esraa A. Arafat, Doaa S. El-Sayed, Hussein K. Hussein, Justin Flaven-Pouchon, Bernard Moussian, Lamia M. El-Samad, Abeer El Wakil, Mohamed A. Hassan

Summary: This study revealed the use of migratory locusts as an insect model to investigate the toxic effects of aluminum oxide nanoparticles on testes and the potential of American cockroach extract to mitigate this toxicity. The accumulation of aluminum in testicular tissues due to the nanoparticles' penetration into the blood-testis barrier was observed. Toxicity induced by aluminum resulted in antioxidant and stress biomarker disorders, DNA damage, and cell apoptosis. However, pretreatment with the cockroach extract counteracted the detrimental effects, demonstrating antioxidant properties and preventing DNA impairment and cell apoptosis.

Summary: The novel food derived from migratory locusts is considered safe for human consumption, with no significant nutritional disadvantages when consumed in accordance with proposed specification limits. While allergens from both the feed and the insect itself may trigger allergic reactions in sensitive individuals, overall consumption of the novel food is deemed safe under the proposed uses and levels.

Identification of neuropeptides and neuropeptide receptor genes in Phauda flammans (Walker)

Hai-Pan Wu, Xiao-Yun Wang, Jin Hu, Ran-Ran Su, Wen Lu, Xia-Lin Zheng

Summary: This study investigated the expression of differentially expressed genes, neuropeptides, and neuropeptide receptor in Phauda flammans. Fifteen neuropeptides and 66 neuropeptide receptor genes were identified. This is the first sequencing and identification of neuropeptides and neuropeptide receptor genes in P. flammans, providing valuable information for further research.

Neuromodulatory pathways in learning and memory: Lessons from invertebrates

Sara Van Damme, Nathan De Fruyt, Jan Watteyne, Signe Kenis, Katleen Peymen, Liliane Schoofs, Isabel Beets

Summary: Animals must continuously adapt to changes in their environment, with learning and memory playing a crucial role in enhancing survival chances. Neuromodulators, particularly monoamines and neuropeptides, influence learning and memory, though our understanding of their functions remains limited. The conservation of neuromodulatory systems and their effects on learning circuits in invertebrates provide valuable insights for understanding pathways involved in learning and memory.

Yolk-deprived Caenorhabditis elegans secure brood size at the expense of competitive fitness

Ellen Geens, Pieter Van de Walle, Francesca Caroti, Rob Jelier, Christian Steuwe, Liliane Schoofs, Liesbet Temmerman

Summary: Oviparous animals support reproduction with yolk as a nutrient source. However, in Caenorhabditis elegans, yolk proteins don't affect fecundity, despite being the majority of embryonic protein pool and carriers for nutrient-rich lipids. Yolk provisioning in C. elegans provides temporal advantage during embryogenesis, increases early juvenile body size, and promotes competitive fitness. Unlike other species, C. elegans relies on yolk as a fail-safe for offspring survival rather than maintaining offspring numbers.

How the Oviduct Lipidomic Profile Changes over Time after the Start of an Obesogenic Diet in an Outbred Mouse Model

Kerlijne Moorkens, Jo L. M. R. Leroy, Jusal Quanico, Geert Baggerman, Waleed F. A. Marei

Summary: This study investigated the changes in lipid metabolism in the oviduct of mice fed an obesogenic diet. The results showed that the obesogenic diet led to an increase in the overall lipid levels and differential regulation of specific lipids in the oviductal epithelium. These lipidomic changes may impact reproductive events in the oviduct, such as fertilization and early embryo development.
