Abundant Z-cyanomethanimine in the interstellar medium: paving the way to the synthesis of adenine

, 2018
We report the first detection in the interstellar medium of the Z-isomer of cyanomethanimine (HNCHCN), an HCN dimer proposed as precursor of adenine. We identified six transitions of Z-cyanomethanimine, along with five transitions of E-cyanomethanimine ...

Engineering Electron Transfer Flux between Cytochrome P450 Enzyme and P450 Reductase to Enhance Serotonin Production in Escherichia Coli

Advanced Science, EarlyView.
The electron transfer flux in CPR‐P450 catalytic system is systematically engineered through: i) enhancing electron transfer rate by redesigning the putative electron transfer pathway of CPR; ii) improving electron‐receiving rate by evolving the heme domain of tryptophan‐5‐hydroxylase (T5H); iii) enlarging electron supply by fine‐tuning NADPH synthesis.

Gentle Label‐Free Nonlinear Optical Imaging Relaxes Linear‐Absorption‐Mediated Triplet

Advanced Science, EarlyView.
The phototoxicity in nonlinear optical microscopy arises mainly from linear absorption of intrinsic biomolecules rather than nonlinear absorption. This mechanism is supported by a reproducible phototoxicity assay based on widely available chicken breast.

Dysregulation of NAD+ metabolism induces a Schwann cell dedifferentiation program [PDF]

, 2018
The Schwann cell (SC) is the major component of the peripheral nervous system (PNS) that provides metabolic and functional support for peripheral axons. The emerging roles of SC mitochondrial function for PNS development and axonal stability indicate the

Apoptotic Bodies Restore NAD and Mitochondrial Homeostasis in Fibroblasts

Advanced Science, EarlyView.
Mesenchymal stem cell‐derived apoptotic bodies (MSC‐ABs) target keloid fibroblasts (KFs), restoring nicotinamide adenine dinucleotide (NAD) metabolism and mitochondrial function, suppressing collagen overproduction, and rebalancing tissue homeostasis, offering a novel therapy for keloid.
