A Systematic Review of Adverse Childhood Experiences and Epigenetic Age Acceleration in Later Adult Life Measured With Second and Third‐Generation Epigenetic Clocks

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT We examined the relationship between adverse childhood experiences (ACEs) and epigenetic age acceleration (EAA) in adulthood as measured by second and third generation epigenetic clocks by performing a systematic review of the literature. The electronic databases MEDLINE and EMBASE were searched on 17 July 2023.

Discovery of a Plant Pictet–Spenglerase With R‐Stereoselectivity

Angewandte Chemie, EarlyView.
Strictosidine synthases (STRs) are plant Pictet–Spenglerases catalyzing the coupling of a secoiridoid with tryptamine. All previously characterized strictosidine synthases are strictly S‐selective. Here, we report the discovery of Epi‐STR, an R‐selective STR ortholog from the medicinal plant Pogonopus speciosus.

Molecular Profiling of Genes Associated With Methylphenidate Pathway Therapy and Discovery of New Variants in Amazonian Amerindian Populations

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT In Attention Deficit Hyperactivity Disorder (ADHD), methylphenidate is one of the most widely used drugs, in which patient response significantly impacts prognosis. This study aimed to characterize the molecular profile of 10 genes associated with methylphenidate therapy.

Alkyltransferase Ribozyme for Site‐Specific N4‐Cytidine Alkylation

Angewandte Chemie, EarlyView.
CSAR is the first ribozyme that catalyzes direct alkylation of an exocyclic amino group of an RNA nucleobase. The ribozyme was isolated as a self‐labeling catalyst from an in vitro selection library and engineered into a trans‐active ribozyme that catalyzes the transfer of a benzyl group from an O6‐modifed guanine to the N4 amino group of a specific ...

Mechanisms of Mitochondrial Toxicity and Cytotoxicity Caused by Pseudomonas aeruginosa Pyocyanin in Human Nasal Epithelial Cells

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Pseudomonas aeruginosa is an opportunistic pathogen in cystic fibrosis‐related chronic rhinosinusitis (CF‐CRS) that produces phenazine metabolites pyocyanin and 1‐hydroxyphenazine (1‐HP), which may have detrimental effects on mitochondria, reactive oxygen species (ROS), Ca2+ signaling, and apoptosis.

A Revised Model for Muscarine Biosynthesis Involving Lysine Trimethylation

Angewandte Chemie, EarlyView.
The fatal mushroom toxin l‐(+)‐muscarine is one of the most prominent natural products. We elucidated its biosynthetic origin in the sweating mushroom Collybia rivulosa based on incorporation of stable isotope‐labeled compounds and extensive mass spectrometric analyses.

Heterogenous Model of Temozolomide Resistance in Glioblastoma Reveals Phenotypic Shifts in Drug Response and Migratory Potential

Advanced NanoBiomed Research, EarlyView.
Glioblastoma mortality is driven by cell invasion and therapeutic resistance. We report a cancer engineering approach to evaluate the behavior of heterogeneous cohorts of temozolomide resistant and responsive GBM cells. We show the effect of physiologically‐relevant metronomic dosing on ensemble drug response and invasion.
