Alternative Pathway for Methyl Supply through the Coupling of SHMT1 and PEMT to Maintain Astrocytic Homeostasis in Parkinson's Disease

Advanced Science, EarlyView.
In Parkinson's disease, SHMT1 downregulation disrupts its interaction with PEMT in astrocytes, reducing SAM levels. This leads to H3K4me1 hypomethylation and decreased Slc1a2/Glul expression, ultimately exacerbating neuroexcitotoxicity and dopaminergic neuron loss.

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

Structure‐Guided Engineering of a Promiscuous O‐Methyltransferase for a SAM Regeneration Biocatalysis Platform of Methylated Pharmaceuticals

Advanced Science, EarlyView.
A substrate promiscuous and regioselective O‐methyltransferase, SmOMT, is functionally and structurally characterized. A double mutant, SmOMTE152A/I306A, exhibited enhanced catalytic activity. By coupling this mutant with a mutant halide methyltransferase, AtHMTV140T, for SAM regeneration, a superior artificial fusion enzyme, AtHMTV140T‐L95‐SmOMTE152A ...
