Change Your Diet: How CO2, Plant Phenology and Genotype Alter Grapevine Quality and Affect Performance and Larval Transcriptome of an Insect Herbivore

Molecular Ecology, EarlyView.
ABSTRACT Herbivorous insects need to cope with changing host plant biochemistry caused by abiotic and biotic impacts, to meet their dietary requirements. Larvae of the multivoltine European grapevine moth Lobesia botrana, one of the main insect pests in viticulture, feed on both flowers and berries.

The Genetics of Host Plant Acceptance in Pea Aphids

Molecular Ecology, EarlyView.
ABSTRACT The evolution of host‐associated sympatric populations in phytophagous insects (so called “host races”) connects adaptive divergence to barriers to gene flow. Pea aphid (Acyrthosiphon pisum) host races specialise on legume species, and because host plant choice leads to assortative mating, the genetic basis of host plant acceptance is key to ...

FlhG Cooperates With the Cell Cycle Regulator GpsB to Confine Peritrichous Flagella in B. subtilis

Molecular Microbiology, EarlyView.
FlhG (orange, with activator helix in green) regulates peritrichous flagellation in Bacillus subtilis by interacting with the C‐ring protein FliY (gray, N‐terminus in red) and the cell wall regulator GpsB (N‐terminus in blue, C‐terminus in red). GpsB recruits PBP1 for peptidoglycan synthesis, linking flagellar assembly to cell wall biosynthesis.

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

Medical and Veterinary Entomology, EarlyView.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

Morin hydrate reduces survival and fertility, delays development and weakens lipid reserves in Aedes aegypti

Medical and Veterinary Entomology, EarlyView.
Morin hydrate promoted mortality and reduced the rate of pupation and egg laying in Aedes aegypti larvae that survive treatment. Morin hydrate reduces the levels of triacylglycerol, the main lipid reserve in A. aegypti larvae. The expression of proteins involved in lipogenesis and lipolysis was downregulated and upregulated, respectively, in larvae ...

A Role for High Mobility Group Box 1 (HMGB1) Release in the Pathogenesis of Gastroesophageal Reflux Disease

Neurogastroenterology &Motility, EarlyView.
Incubation of esophageal epithelial cells with a weakly acidic (pH 5) bile salt (deoxycholic acid) induces translocation of HMGB1 from the nucleus to the cytosol, and its subsequent release from the cell. This process can be ameliorated by pre‐treatment with the antioxidant, curcumin.

Human Glutathione S-Transferases

Seminars in Liver Disease, 1998
Human glutathione S-transferases (GSTs) are a functionally diverse family of soluble enzymes of detoxification that use reduced glutathione (GSH) in conjugation and reduction reactions. Toxic electrophiles, including a variety of carcinogens, are substrates for the GSTs and after conjugation or reduction they are more easily excreted into bile or urine.

Marine Glutathione S-Transferases

Marine Biotechnology, 2007
The aquatic environment is generally affected by the presence of environmental xenobiotic compounds. One of the major xenobiotic detoxifying enzymes is glutathione S-transferase (GST), which belongs to a family of multifunctional enzymes involved in catalyzing nucleophilic attack of the sulfur atom of glutathione (gamma-glutamyl-cysteinylglycine) to an

Human glutathione S-transferases

International Journal of Biochemistry, 1994
1. Multiple forms of glutathione S-transferase (GST) isoenzymes present in human tissues are dimers of subunits belonging to three distinct gene families namely alpha, mu and pi. Only the subunits within each class hybridize to give active dimers. 2.

Glutathione S-Transferases

1996
Glutathione (GSH), the most ubiquitous and abundant nonprotein thiol, is essential in numerous detoxification reactions and is therefore considered a chemoprotectant. In the human, levels of GSH range from 30μM in plasma to 3mM in kidney proximal tubules; tumors of various organs can contain up to 10mM GSH [1].
