Obesity‐Associated TRIM15 Promotes the Proliferation of Esophageal Adenocarcinoma Through the YY2/FOXRED1 Axis

open access: yesAdvanced Science, EarlyView.
The study identifies TRIM15 as a key driver in the development of obesity‐associated esophageal adenocarcinoma (EAC). Mechanistically, TRIM15 degrades YY2 through the proteasome pathway, suppressing FOXRED1 transcription and ultimately accelerating tumor proliferation.

Minimally Invasive Chemical Biopsy Needle with Self‐Wettable Extraction Phase For In Vivo Tissue Sampling During Medical Procedures

open access: yesAdvanced Science, EarlyView.
A new tissue sampling device using an acupuncture needle with bio‐compatible extraction sorbents in the recessed section is developed. The coating material using self‐wettable particles doesn't require solvent activation after sterilization. This device is applied for the anti‐cancer drug concentration monitoring during the in vivo lung perfusion ...

Characterization and Determination of the Alkaloid Metabolites of Evodiae fructus in Rat Urine by Liquid Chromatography-Tandem Mass Spectrometry Detection

open access: yesMolecules, 2011
The lack of authentic standards limits the quantitative analysis of herbal drugs in biological samples. This present work demonstrated a practicable assay of herbs and their metabolites independent of the availability of authentic standards.

Theta-Glass Capillaries in Electrospray Ionization: Rapid Mixing and Short Droplet Lifetimes

open access: yesAnalytical Chemistry, 2014
Double-barrel wire-in-a-capillary electrospray emitters prepared from theta-glass capillaries were used to mix solutions during the electrospray process. The relative flow rate of each barrel was continuously monitored with internal standards.

Allosteric Modulation of Pathological Ataxin‐3 Aggregation: A Path to Spinocerebellar Ataxia Type‐3 Therapies

open access: yesAdvanced Science, EarlyView.
This study uncovers a new allosteric site in the Josephin domain of ataxin‐3 targeted by the molecular tweezer CLR01, which modulates protein aggregation, improves synaptic function in neuronal cells, and delays motor dysfunction in animal models.

NNMT Orchestrates Metabolic‐Epigenetic Reprogramming to Drive Macrophage‐Myofibroblast Transition in Hypertrophic Scarring

open access: yesAdvanced Science, EarlyView.
In macrophage‐myofibroblast transition, upregulated NNMT depletes S‐Adenosylmethionine‌ (SAM) and nicotinamide adenine dinucleotide(NAD+), thereby triggering epigenetic reprogramming via Histone H3 Lysine 27 acetylation (H3K27ac) accumulation at the promoter region of master transcription factor Prrx1.
