Aging as a Loss of Goal‐Directedness: An Evolutionary Simulation and Analysis Unifying Regeneration with Anatomical Rejuvenation

open access: yesAdvanced Science, EarlyView.
The paper proposes that the root cause of aging is the loss of anatomical goal‐directedness after development. Using evolutionary neural cellular automata simulations, the authors show that after the organism has reached its developmental homeostatic setpoint (the adult morphology), the absence of target state to pursue leads to a drifting anatomical ...

Integrin‐Piezo1 Axis Drives ECM Remodeling and Invasion of 3D Breast Epithelium

open access: yesAdvanced Science, EarlyView.
Mechanical stiffening of the extracellular matrix around mature mammary acini induces sequential remodeling phases. An early response disrupts the basement membrane and promotes fibronectin secretion, followed by delayed invasion with matrix reorganization and proliferation.

SP1‐Mediated Glycolytic Reprogramming Promotes Tumorigenesis and Progression in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
Laser capture microdissection‐based proteomics of pancreatic intraepithelial neoplasia (PanIN) identifies specificity protein 1 (SP1) as a key driver of tumorigenesis and progression in pancreatic cancer through glycolytic remodeling. SP1 enhances aerobic glycolysis by transcriptionally activating 6‐phosphofructo‐2‐kinase/fructose‐2,6‐bisphosphatase ...

Uric Acid Functions as an Endogenous Modulator of Microglial Function and Amyloid Clearance in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
Higher serum UA levels are associated with reduced AD risk in epidemiological studies. UA enhances microglial phagocytic capacity primarily by restoring CD36 and TREM2 receptor recycling that is impaired by Aβ exposure. Therapeutically, UA supplementation improves cognitive function and reduces neuropathology in AD mouse model by enhancing microglial ...

Strategic Timing of Gene Silencing: Cellular Kinetics‐Based Administration of siRNA for Optimized Photothermal Cancer Treatment

open access: yesAdvanced Science, EarlyView.
Coordinating therapy with gene expression kinetics emerges as a key strategy for maximizing nanomedicine efficacy in aggressive cancers. A hybrid nanocarrier delivering HSP70‐targeting siRNA demonstrates this chronotherapeutic principle through systematic cellular profiling.

Partial Reprogramming in Senescent Schwann Cells Enhances Peripheral Nerve Regeneration via Restoration of Stress Granule Homeostasis

open access: yesAdvanced Science, EarlyView.
In this study, it is discovered that pathological accumulation of Runx2+ Schwann cell clusters​ during axonal regeneration is a key factor impairing nerve repair in aging. This pathology is associated with ​dysregulation of stress granule homeostasis.

Cytological Classification Diagnosis for Thyroid Nodules via Multimodal Model Deep Learning

open access: yesAdvanced Science, EarlyView.
This study introduces AI‐TFNA, an innovative artificial intelligence model designed to assist cytopathologists in classifying thyroid nodules based on The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). The model effectively differentiates between benign and malignant thyroid nodules, demonstrating significant potential as a screening ...

Alkaline–Acid Intestine Environment Controlled by A Carbonic Anhydrase Gene Influences Synthesis of Sex Pheromone by Symbionts

open access: yesAdvanced Science, EarlyView.
A model proposing that elevated rectal expression of CAh1 in males alkalinizes the environment to regulate Bacillus production of a male‐specific sex pheromone. Abstract The intricate interplay between animals and their intestinal microbes is pivotal in shaping various aspects of animal biology.
