Fertility and age

open access: yesJournal of Human Reproductive Sciences, 2010
The changing social scenario together with economic growth and an increase in job opportunities has to a great extent reduced gender inequality and has resulted in more and more older women seeking help from infertility clinics. Fertility and aging have always been closely linked and the age of the female partner remains the single most important ...

An Insect Salivary Sheath Protein Triggers Plant Resistance to Insects and Pathogens as a Conserved HAMP

open access: yesAdvanced Science, EarlyView.
The salivary sheath protein myosin from SBPH is critical for the formation of the salivary sheath and feeding. However, myosin functions as a HAMP and triggered plant BAK1‐mediated PTI responses, which include the activation of calcium signaling pathways, MAPK phosphorylation, ROS bursts, and cell death, thereby triggering JA pathway.

Comprehensive Characterization of Bihormonal Cells and Endocrine Cell Lineages in Mammalian Pancreatic Islets

open access: yesAdvanced Science, EarlyView.
This study integrates dual‐reporter genetics, imaging flow cytometry, and single‐cell sequencing to characterize rare bihormonal cells in mouse and human pancreatic islets. Gcg⁺Ins⁺ cells resemble α‐cells rather than transitional states. Cross‐species gene network analysis refines islet cell taxonomy and reveals human‐specific δ‐cell subtypes ...

Inhibition of Ferroptosis Delays Aging and Extends Healthspan Across Multiple Species

open access: yesAdvanced Science, EarlyView.
This study identifies ferroptosis as a key driver of cellular senescence, with its inhibition delaying aging and extending healthspan across species. During senescence, ferroptosis worsens, increasing oxidative stress and lipid peroxidation, which accelerate aging.

Neophytadiene, a Plant Specialized Metabolite, Mediates the Virus‐Vector‐Plant Tripartite Interactions

open access: yesAdvanced Science, EarlyView.
Tomato chlorosis virus (ToCV) infection induces production of neophytadiene, a volatile resulting from chlorophyll degradation that is highly attractive to whiteflies. OBP2, an odorant‐binding protein from insect vector B. tabaci, exhibits a strong binding affinity for neophytadiene.

Virome and Experimental Analysis Reveal Tryptophan‐Like Dissolved Organic Matter Contributes to the Persistence of Plant Viruses in River Water

open access: yesAdvanced Science, EarlyView.
Tryptophan‐like dissolved organic matter (Try‐like DOM), a key component of organic matter in river ecosystems, demonstrates significant protective effects against plant viruses. The protective mechanism operates via a “swimming firewall” mode, whereby free Try‐like DOM attenuates ultraviolet (UV) radiation and scavenges reactive oxygen species ...

PABPN1 Couples the Polyadenylation and Translation of Maternal Transcripts to Mouse Oocyte Meiotic Maturation

open access: yesAdvanced Science, EarlyView.
This study reveals that cytoplasmic PABPN1 is essential for mouse oocyte meiotic maturation by coordinating polyadenylation, translation, and degradation of maternal mRNAs. Pabpn1 knockout disrupts CDK1 activation, spindle formation, and chromosome alignment by impairing maturation‐promoting factor (MPF) regulation and BTG4‐mediated deadenylation ...

AlphaFold‐Guided Bespoke Gene Editing Enhances Field‐Grown Soybean Oil Contents

open access: yesAdvanced Science, EarlyView.
An AlphaFold‐guided method is developed to functionally optimize soybean sugar transporters and achieve bespoke gene editing of GmSWEET10a/b to improve oil content in an elite soybean cultivar in multi‐year, multi‐site field trials. The combination of AI‐guided protein design and gene editing may unlock a huge potential to improve the genetic trait de ...

Dynamic and Stable Core Microbiota Assist Plants in Enriching Selenium and Reducing Cadmium Absorption

open access: yesAdvanced Science, EarlyView.
During different developmental stages of plants in natural Se–Cd coexisting soils, there is a group of rhizosphere microorganisms with highly dynamic abundance. The abundance variation of these microorganisms is strongly positively correlated with available Se and strongly negatively correlated with available Cd.
