The Mitochondrial Protein RESISTANCE to APHIDS 9 Interacts with S40 to Resist Aphid Infestation by Modulating Reactive Oxygen Species Homeostasis in Maize (Zea mays)

open access: yesAdvanced Science, EarlyView.
This study identifies the mitochondrial protein RTA9, a member of the Domain of Unknown Function 641 family, together with its partner S40, as key regulators of aphid resistance in maize. RTA9 promotes S40 degradation and modulates reactive oxygen species accumulation.

Norepinephrine Induces Sertoli Cell Ferroptosis via Receptors Desensitization Causing Stress‐Related Male Reproductive Dysfunction

open access: yesAdvanced Science, EarlyView.
Psychological stress activates the sympathetic–adrenal axis, elevating norepinephrine (NE) and suppressing reproductive hormones, thereby impairing male reproduction. Excess NE overactivates and desensitizes β‐adrenergic receptors (β‐ARs), triggering Sertoli cell ferroptosis and disrupting spermatogenesis.

Therapeutic Repair of Sperm Quality Decline Caused by Polytetrafluoroethylene

open access: yesAdvanced Science, EarlyView.
Exposure to PTFE (teflon), a commonly used microplastic in non‐stick cookware, significantly reduces sperm quality in both humans and mice. Specifically, PTFE induces the disruption of sperm cytoskeleton and F‐actin assembly through targeting SKAP2 in haploid spermatid.
