Summary: This study aimed to evaluate the effects of hatching enzymes on egg envelope digestion during the hatching period in male brooding seahorses. The genes encoding two hatching enzymes, HCE and LCE, were cloned and functionally characterized from the lined seahorse. Both HCE and LCE were found to independently digest and soften the egg envelopes of the seahorse, with HCE and LCE showing similar substrate specificities towards synthetic peptides.

Summary: This study reports the identification of a novel digestive enzyme called pactacin, belonging to the astacin metalloprotease family, specifically found in teleosts. Through analyzing pactacin enzymes in pot-bellied seahorse and medaka, it was discovered that these enzymes are commonly expressed in the pancreas and converted to active forms in the intestine. The findings suggest a unique digestive enzyme evolution in teleosts, with potential implications for understanding nutrient extraction in vertebrates.

Summary: Within the blood-gorging insect Rhodnius prolixus, corticotropin-releasing factor/diuretic hormones (CRF/DHs) modulate feeding, diuresis, and reproduction. This study explores the role of Rhopr-CRF/DH in female reproduction and reveals its co-localization with the glycoprotein hormone GPB5. Knockdown of Rhopr-CRF/DH-R2, the receptor for Rhopr-CRF/DH, accelerates egg production and alters the expression of vitellogenin and its receptor, suggesting the involvement of the CRF-signaling pathway in reproduction.

Summary: In alternative poultry production systems, the storage of hatching eggs is an important aspect that is less standardized than in intensive poultry farming. This study investigated the effect of long-term storage of game farmed quail eggs on hatchability, weight loss, chick weight, and incubation length. The results showed that hatchability decreased when storage was extended to 35 days, and the eggs progressively lost more weight as the storage time increased. The incubation period also increased with storage time, while hatching synchrony decreased.

Summary: The study showed that turning eggs 4 times daily combined with one SPIDES treatment during 14 days storage period resulted in the highest hatchability in both young and old broiler grandparent flocks. Advanced blastoderm development was observed with turning and SPIDES treatment, particularly in eggs from the old flock. Eggs from the young flock had better hatchability compared to the old flock, and turning during storage improved hatchability by reducing late embryonic mortality.

Summary: In broiler breeder production, cracked or broken egg shells account for 2% of rejected hatching eggs, leading to reduced hatchability and lower chick quality. A study was conducted to examine the effect of sealing egg-shell cracks with surgical tape on hatching parameters. The results showed that sealing the cracks with tape improved egg weight loss during incubation and reduced embryonic mortality, resulting in hatching percentages comparable to the positive control group.

Summary: Respiration during egg incubation is closely related to fertilization status and embryo growth. Oxygen consumption and CO2 emission gradually increased during incubation, reaching maximum values when the shells were broken by the chick. Models using random forest and support vector machine were established to classify eggs based on respiration differences. Furthermore, a linear model demonstrated the relationship between chicken embryo respiration and various growth indicators.

Summary: This study reveals significant differences in the structure and protein composition of the egg envelopes of common carp adhesive eggs and grass carp semi-buoyant eggs, with common carp eggs having a thicker egg envelope and adhesive layer. Proteomic changes in common carp adhesive eggs after fertilization suggest a role in cell and fish egg morphology maintenance. Proteins upregulated in common carp adhesive eggs after fertilization, such as coagulation factor XIII A, zona pellucida proteins, and cystatin, may play a role in egg envelope hardening and embryonic development protection. Additionally, higher levels of alpha-2-macroglobulin-like protein in fertilized common carp eggs indicate potential for effective immune defense.

Summary: The seahorse is a unique teleost fish with special morphology, including bony plates and spines, and males possessing a brooding organ called the brood pouch. The flame cone cells, found in the brood pouch and spines, express a gene called pgrich which is not present in related species. This pgrich gene may have originated from the elastin gene with the involvement of transposable elements and obtained its novel function in the flame cone cells during seahorse evolution.

Summary: During the evolution, gene duplication occurred in the astacin metalloprotease family genes, especially in the teleost lineage. One of the duplicated genes, patristacin, is present in the brood pouch and found on the same chromosome as other c6ast genes. Phylogenetic analysis revealed that the patristacin gene homologs were found in only several lineages, with the highest occurrence in the Percomorpha group of teleosts. Within the Atherinomorphae group, platyfish possess eight patristacin gene homologs, with only XmPastn2 showing strong expression in various organs, particularly in mucus-secreting cells found in the epidermis around the jaw.
