Calcium Ion Induces Proteolysis of Vitellogenin from Tilapia Oreochromis niloticus [PDF]

open access: yes, 1995
Vitellogenin from the serum of tilapia Oreochromis niloticus was proteolytically cleaved by incubating with only Ca^ at 37℃. Although this proteolysis of vitelloge nin by Ca^ was time-consuming (144hr), Vitellogenin was never cleaved in the presence of ...

Syntaxin-1A Silencing by RNAi Disrupts Growth and Reproduction in the Asian Citrus Psyllid, Diaphorina citri

open access: yesInsects
Diaphorina citri is the primary global vector of “Candidatus Liberibacter asiaticus”, the bacterium responsible for Huanglongbing. Syntaxin-1A (Syx1A), a member of the Qa-SNARE family, is essential for vesicle fusion and signal transduction, though its ...

Oxidative stress in honey bees (Apis mellifera) and small carpenter bees (Ceratina calcarata) across different landscapes

open access: yesPhysiological Entomology, EarlyView.
First comparative study in oxidative stress between wild bees and managed bees. Bees collected from organic landscapes exhibited the lowest OX levels. Pesticide profiles were different among landscapes. Abstract Oxidative stress (OX) is a state of imbalance between antioxidants and reactive oxygen species, which are the byproducts of oxidative ...

Hormonal control of protein synthesis in the fat body of Leptinotarsa decemlineata

open access: yes, 1979
This thesis deals with the hormonal control of protein synthesis in the female fat body of Leptinotarsa decemlineata Say. The results are discussed in relation to reproduction (obtained by rearing under long day conditions) and the preparation for ...

Comparative analysis of immune responses in ovipositing and non‐ovipositing females of European earwig Analyse comparative de la réponse immunitaire avant et après la ponte chez le forficule européen

open access: yesPhysiological Entomology, EarlyView.
Oviposition and care decrease the total haemocyte concentration. Oviposition and care affect haemocyte type proportions. Serratia marcescens challenge does not affect the immune cell parameters. Abstract Reproduction and immunity are essential biological processes that compete for resources and energy.

A Quarter Century of EHD Protein Research: From Endosomal Recycling to Ciliopathies

open access: yesTraffic, Volume 27, Issue 3, September 2026.
Human EHD protein subcellular localization. ABSTRACT Eps15 homology domain‐containing proteins comprise a conserved family of membrane‐remodeling ATPases that regulate endocytic trafficking, membrane fission, receptor recycling, primary ciliogenesis and membrane dynamics across eukaryotes. Since the initial identification of EHD1 and its Caenorhabditis

Tracking the Pulse of the Dunes: Seasonal Metabolic Responses of Liolaemus arambarensis to Climatic Variability

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 6, Page 568-580, July 2026.
ABSTRACT Seasonal environmental fluctuations profoundly influence ectothermic vertebrates, regulating their physiology, metabolism, and life cycles. This study investigated the metabolic and morphometric seasonal dynamics of the subtropical sand lizard Liolaemus arambarensis, an endangered species endemic to the coastal dunes of southern Brazil.

Biosynthesis of mosquito vitellogenin.

open access: yesJournal of Biological Chemistry, 1990
Vitellogenin (Vg), the hemolymph precursor to the major yolk protein in mosquitoes, is synthesized in the fat body of blood-fed females. Mosquito Vg consists of two subunits with Mr = 200,000 and 66,000. Here, we demonstrate that both the Vg subunits are first synthesized as a single precursor.
