Aging and the Spectral Properties of Brain Hemodynamics

open access: yesAdvanced Science, EarlyView.
As the brain ages, its metabolic demands decline—but not uniformly. Here, spectral slope flattening of resting‐state fMRI signals is proposed as a potential biomarker of pathologic brain aging. A subset of older adults diverges from youthful spectral and metabolic patterns, with changes linked to frontal white matter pathology and regional loss of ...

Gompertz Law‐Based Biological Age (GOLD BioAge): A Simple and Practical Measurement of Biological Ageing to Capture Morbidity and Mortality Risks

open access: yesAdvanced Science, EarlyView.
The Gompertz law‐based biological age metric (GOLD BioAge) introduces interpretable convenient and interpretable calculations to capture mortality, disease, and frailty risks. Its applications to proteomics and metabolomics (ProtAge and MetAge) demonstrate clinical potential to enhance aging evaluation and prevent age‐related diseases.

Novel ATR/PARP1 Dual Inhibitors Demonstrate Synergistic Antitumor Efficacy in Triple‐Negative Breast Cancer Models

open access: yesAdvanced Science, EarlyView.
Novel ATR/PARP1 dual inhibitors are developed for the first time. Advanced lead B8 effectively reduces cell viability in vitro and suppresses tumor growth in vivo, with better potency than ATRi and PARPi alone or in combination. Mechanistically, B8 induces apoptosis, arrests the cell cycle, and inhibits cancer cells colony formation, migration, and ...

Novel Cyano‐Artemisinin Dimer ZQJ29 Targets PARP1 to Induce Ferroptosis in Pancreatic Cancer Treatment

open access: yesAdvanced Science, EarlyView.
A novel artemisinin derivative dimer has been synthesized, and its significant potential as an anti‐cancer agent. The study indicated that ZQJ29 effectively inhibited the proliferation of pancreatic cancer cells in vitro and in vivo. Additionally, these investigations have unveiled ZQJ29 as a new potent PARP1 inhibitor, with the capability to induce ...

Long Term High‐Salt Diet Induces Cognitive Impairments via Down‐Regulating SHANK1

open access: yesAdvanced Science, EarlyView.
The study identifies a novel mechanistic link between long‐term HS diet and cognitive impairment, wherein PKA/CREB axis inactivation leads to SHANK1 reduction, synaptic damage, and cognitive deficits. Abstract High‐salt (HS) diet is an established risk factor for cognitive impairment, but the underlying mechanisms remain unclear.
