Promoting Autophagy Mitigates Stress‐Induced Remodeling in Patient iPSC‐CMs with the Phospholamban R9C Mutation

open access: yesAdvanced Science, EarlyView.
The Phospholamban (PLN) R9C mutation reduces SERCA2a binding, increasing calcium recycling and baseline contractility. However, the excess of free PLN promotes pentamer formation, limiting phosphorylation and blunting β‐adrenergic signaling. Under cardiac stress, enhanced functional demands overwhelm proteostasis in PLN R9C cells, leading to misfolded ...

Hungry for Knowledge: Octopamine Signaling Regulates Hunger‐Enhanced Olfactory Learning

open access: yesAdvanced Science, EarlyView.
Researchers demonstrate that hunger state facilitates both aversive and appetitive olfactory learning. Two distinct octopamine signaling pathways are involved in aversive or appetitive memory formation in the hunger state. And, hunger state also facilitates the formation of both types of memories via an evolutionarily conserved norepinephrine (the ...

Adverse Effects on β‐Adrenergic Receptor Coupling: Ischemic Postconditioning Failed to Preserve Long‐Term Cardiac Function

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundIschemic preconditioning (IPC) and ischemic postconditioning (IPoC) are currently among the most efficient strategies protecting the heart against ischemia/reperfusion injury. However, the effect of IPC and IPoC on functional recovery following

Targeted 2‐Deoxy‐D‐Ribose Delivery by Biomimetic Nanoplatform Activates EGFR for Accelerated Heart Valve Endothelialization

open access: yesAdvanced Science, EarlyView.
This study develops a biomimetic nanoplatform using erythrocyte membrane‐camouflaged, CD144 antibody‐functionalized nanoparticles to deliver 2‐deoxy‐D‐ribose (2dDR). This system promotes heart valve endothelialization by enhancing endothelial cell migration and proliferation via EGFR activation, while improving hemocompatibility.

Integrative Omics Defines Metabolic Biomarkers and Genetic Regulatory Mechanisms of Mortality Risk

open access: yesAdvanced Science, EarlyView.
Understanding mortality mechanisms remains a fundamental challenge. Through multi‐omics analysis of a three‐generation chicken model, are identified 45,585 mQTLs and establish a 16‐metabolite predictor of mortality. An inflammation‐growth trade‐off and evolutionarily conserved pathways involving butyrate–microbiota interactions and L‐cysteine's dual ...

How should anti-hypertensive medications be adjusted before screening for primary aldosteronism?

open access: yesJournal of the Formosan Medical Association
Anti-hypertensive medications may affect plasma renin activity and/or plasma aldosterone concentration, misleading the interpretation of the aldosterone-to-renin ratio when screening for primary aldosteronism. The Task Force of Taiwan PA recommends that,

Crossing the Blood–Brain Barrier with Molecularly Imprinted Polymeric Nanocarriers: An Emerging Frontier in Brain Disease Therapy

open access: yesAdvanced Science, EarlyView.
Molecularly imprinted polymeric nanocarriers (nanoMIPs) offer robust, antibody‐mimetic platforms to overcome the blood‐brain barrier. The article surveys nanoMIP design and ligand‐directed surface engineering that harness receptor‐mediated transcytosis, and highlights therapeutic and diagnostic applications in neurodegeneration, brain tumors and ...

Gabpα‐Pparγ Complex Determines Glycolytic Capacity and Lactic Acid Homeostasis in Brown Fat

open access: yesAdvanced Science, EarlyView.
This study identifies the Gabpα–Pparγ complex as a key transcriptional regulator that couples glycolysis to lactate‐driven thermogenesis in brown adipose tissue by directly activating Eno1 transcription. ‌Competitive disruption of this interaction impairs lactate metabolism and thermogenic capacity.
