Hijacking the Host Clock: A Nematode Effector Antagonizes Soybean Circadian Defense and Translation Control

open access: yesAdvanced Science, EarlyView.
Soybean employs its circadian clock, governed by GmCCA1, to rhythmically defend against soybean cyst nematodes. The pathogen retaliates by secreting the effector Hg4E02, which hijacks the clock to suppress defense and co‐opt the host's translation machinery for nutrient acquisition.

Brief increases in corticosterone affect morphology, stress responses, and telomere length, but not post-fledging movements, in a wild songbird

open access: yes, 2018
Organisms are frequently exposed to challenges during development, such as poor weather and food shortage. Such challenges can initiate the hormonal stress response, which involves secretion of glucocorticoids. Although the hormonal stress response helps

Trade-offs between personal immunity and reproduction in the burying beetle, N. vespilloides [PDF]

open access: yes, 2014
We know that parental investment and immune investment are costly processes, but it is unclear which trait will be prioritised when both may be required.

Sex‐Specific Regulation of Glycemic Homeostasis by Theabrownin from Pu‐erh Tea

open access: yesAdvanced Science, EarlyView.
Pu‐erh tea's key component, theabrownin (TB), lowers blood glucose in a sex‐specific manner. In females, estrogen boosts intestinal MUC2 production, which dramatically enhances TB's ability to inhibit the carbohydrate‐digesting enzyme α‐glucosidase.

Transcriptome and proteome analyses reveal genes and signaling pathways involved in the response to two insect hormones in the insect-fungal pathogen Hirsutella satumaensis

open access: yesmSystems
The insect hormones ecdysone (20E) and juvenile hormone III (JH) have been demonstrated to stimulate the secretion of conidia mucilage and pigments in Hirsutella satumaensis. However, the underlying mechanisms remain elusive.

Timing is everything: Drivers of interannual variability in blue whale migration. [PDF]

open access: yes, 2020
Blue whales need to time their migration from their breeding grounds to their feeding grounds to avoid missing peak prey abundances, but the cues they use for this are unknown.

Action of the Metalloproteinases in Gonadal Remodeling during Sex Reversal in the Sequential Hermaphroditism of the Teleostei Fish Synbranchus marmoratus (Synbranchiformes: Synbranchidae) [PDF]

open access: yes, 2018
Teleostei present great plasticity regarding sex change. During sex reversal, the whole gonadincluding the germinal epithelium undergoes significant changes, remodeling, and neoformation.However, there is no information on the changes that occur within ...

Oil‐Coated Nanoplastics Induce Rapid Membrane Disruption and Severe Intestinal Injury

open access: yesAdvanced Science, EarlyView.
Oil‐rich food contact dramatically amplifies MNP release from plastic takeout containers, producing oil‐coated nanoplastics with altered surface properties and rapid membrane‐disruptive effects. These particles cause severe intestinal barrier damage and immune dysfunction in mice, and risk modeling suggests that long‐term gastrointestinal burdens may ...

Specificity of the juvenile hormone binding protein: The geometrical isomers of juvenile hormone I [PDF]

open access: yesProceedings of the National Academy of Sciences, 1978
The binding of the geometrical isomers (≥99% pure) of juvenile hormone I to the hemolymph juvenile hormone binding protein of Manduca sexta (Lepidoptera, Sphingidae) was analyzed. A technique is described for isomer separation by micropreparative high-resolution liquid chromatography.
