Implications of Maternal Toxicant Effects on Size‐Dependent Fisheries' Management: A Meta‐Analysis
Fish and Fisheries, Volume 27, Issue 4, Page 895-911, July 2026.Larger, older fish transfer higher mercury and PCB concentrations to their eggs, significantly reducing offspring hatching success, survival and growth rates in contaminated aquatic ecosystems. These findings suggest that the reproductive benefits of big old fat fecund female fish may be compromised by maternal toxicant transfer in polluted waters ...

Detection of vitellogenin in a subpopulation of sea urchin coelomocytes [PDF]
, 1994 Sea urchin vitellogenin is a high molecular weight glycoprotein, which is the precursor of the major yolk protein present in the unfertilized egg. Vitellogenin processing into the major yolk protein and its further enzymatic cleavage during sea urchin ...

The FASEB Journal, Volume 40, Issue 12, 30 June 2026.Analyses of cytochrome P450 1a (CYP1A)‐knockout (KO) Javanese medaka (Oryzias javanicus) revealed that CYP1A is involved in glucose regulation and reproduction. In the KO fish, significant increases in hepatic transcripts of insulin, glucagon, and somatostatin genes, as well as elevated blood glucose, liver mass, and liver triglyceride levels ...

The vitellogenin gene family of Aedes aegypti
, 1987 We have been interested in identifying genes that play a role in reproduction of the mosquito Aedes aegypti. Our interests are currently focused on the vitellogenin genes which in the mosquito are expressed only in the fat body in response to the insect ...

genesis, Volume 64, Issue 3, June 2026.ABSTRACT Optimizing transient expression systems in fish embryos is crucial for rapid gene function analysis. Here, we established an efficient system in medaka (Oryzias latipes) embryos by evaluating nucleic acid type and injection site. Our results revealed that injecting the elongation factor 1αA (ef1αA) promoter‐driven plasmid into the yolk yielded

Phylogeny and multiple sequence alignment of lepidopteran vitellogenin.
, 2023 (A) Phylogenetic tree of vitellogenin homologs in lepidoptera insects. A neighbor-joining tree was constructed using MEGA 5 software [73]. Amino acid sequences were obtained from the UniProt database (https://www.uniprot.org).

Histochemical characteristics of the vitellogenic oocytes of the bluefin tuna, Thunnus thynnus L.
Ciencias Marinas, 2002 Very little information is available with respect to dynamic aspects of oocyte development and to yolk composition of tuna species. Since histological approaches can offer considerable information about the ovarian development of fish, and because ...

Innate immunity shapes the persistent transmission of plant viruses by insect vectors
New Plant Protection, Volume 3, Issue 2, June 2026.In this review, we focus on two key aspects of the virus–vector interplay: (1) persistently transmitted viruses utilize host factors to overcome transmission barriers; and (2) molecular recognition activates antiviral immunity and subsequent viral counter‐defense. Understanding these interactions offers critical insights for developing novel strategies
