Autophagy Activators Normalize Aberrant Tau Proteostasis and Rescue Synapses in Human Familial Alzheimer's Disease iPSC‐Derived Cortical Organoids

Advanced Science, EarlyView.
A new cerebrocortical organoid model using isogenic hiPSCs with familial Alzheimer's mutations recapitulates key AD features, including amyloid‐beta and phospho‐Tau aggregation, neuronal hyperexcitability, and synapse loss. Single‐cell RNA‐seq reveals aberrant pathways in excitatory and inhibitory neurons.

Leveraging Diamines to Unlock the Mn‐MACHO Catalyst in the Reduction of CO2 to Methanol

Angewandte Chemie, EarlyView.
CO2 hydrogenation to methanol using a Mn–MACHO catalyst was achieved without Lewis acid promoters, delivering TONs up to 45.2. Diamines, by driving a highly exergonic double amidation reaction, divert formate resting states toward the active catalyst. The correlation between ΔGamidation and methanol productivity enables the rational design of the amine

Ornithine Decarboxylase mRNA is Stabilized in an mTORC1-dependent Manner in Ras-transformed Cells [PDF]

, 2012
Upon Ras activation, ODC (ornithine decarboxylase) is markedly induced, and numerous studies suggest that ODC expression is controlled by Ras effector pathways. ODC is therefore a potential target in the treatment and prevention of Ras-driven tumours. In

Spatially Resolved Multiomics Reveals Metabolic Remodeling and Autophagy Activation in Adamantinomatous Craniopharyngiomas

Advanced Science, EarlyView.
Multiomics integration analysis reveals the “cystic fluid–tumor cell” metabolic coupling that mediates active choline/ethanolamine uptake of tumor cells from cystic fluid and PC/PE synthesis pathways reprogramming that mediating autophagy pathway activation within ACP. ABSTRACT Adamantinomatous craniopharyngioma (ACP), a benign yet highly recurrent and

Stereospecific Assembly of Triply Chiral Pseudopeptidic Cages Through Dynamic Dual Chirality Transfer

Angewandte Chemie, EarlyView.
The spontaneous assembly of triply chiral (L, Δ, P or D, Λ, M) cages has been achieved from a simple tripodal chiral effector based on phenylalanine tris(amidoamine), non‐chiral bipyridine dialdehyde, and a metal ion. Orthogonal imine bond and iron (II) coordination generate a single combination of chiral elements, while configurationally stable ...

A Simplified Three‐Tailed N‐Alkyl Phosphoramidate Lipid Platform Enables Inguinal Adipose‐Accumulated mRNA Delivery for Anti‐Obesity Therapy

Advanced Science, EarlyView.
This study develops an mRNA therapy encoding a long‐acting GLP‐1/FGF21 fusion protein. A three‐tailed ionizable lipid engineered three‐component lipid nanoparticle delivers the mRNA to inguinal adipose tissue. In obese mice, this targeted, dual‐hormone treatment potently reduces body weight, fat mass, presenting a localized strategy for metabolic ...

Coxsackievirus B3 Responds to Polyamine Depletion via Enhancement of 2A and 3C Protease Activity

Viruses, 2019
Polyamines are small positively-charged molecules abundant in eukaryotic cells that are crucial to RNA virus replication. In eukaryotic cells, polyamines facilitate processes such as transcription, translation, and DNA replication, and viruses similarly ...
