Experiencing 50 Years of Synergistic Development in Structural Biology and Enzymology

open access: yesJournal of the Chinese Chemical Society, EarlyView.
Picture of Sunney Chan with Academia Sinica (AS) President James C. Liao and three Vice Presidents: Shin‐Kun Peng (left one), Tang K. Tang (right one), and Mei‐Yin Chou (right 2), taken at the annual Chinese New Year's Banquet of AS, February 7, 2025. This was likely Sunney's last appearance in formal activities of AS.

HEPATIC AMINOPYRINE N-DEMETHYLASE SYSTEM: EFFECT OF CYANIDE ON MICROSOMAL N-DEMETHYLASE ACTIVITY

open access: yesJapanese Journal of Pharmacology, 1977
Cyanide, an inhibitor of many hemoproteins, was shown to affect a number of microsomal drug-metabolizing activities catalyzed by cytochrome P-450. The N-demethylation reaction of aminopyrine was inhibited noncompetitively by this inhibitor in microsomal preparations from rats.

Histone Lysine Demethylases and Their Impact on Epigenetics

open access: yes, 2006
Methylation marks on the lysine residues of histone proteins are thought to contribute to epigenetic phenomena in part because of their apparent irreversibility.

Fat Mass and Obesity‐Associated Protein Contributes to Tumorigenesis and Drug Resistance of Diffuse Large B‐Cell Lymphoma by Suppressing N6‐Methyladenosine Methylation of Myc

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Ibrutinib resistance remains a major obstacle in the treatment of diffuse large B‐cell lymphoma (DLBCL). Fat mass and obesity‐associated protein (FTO) has been implicated in drug resistance through its regulation of N6‐methyladenosine (m6A) modifications; however, whether FTO mediates ibrutinib resistance in DLBCL remains unclear.

A convenient research strategy for functional verification of epigenetic regulators during spermatogenesis

open access: yesAsian Journal of Andrology
Spermatogenesis is a fundamental process that requires a tightly controlled epigenetic event in spermatogonial stem cells (SSCs). The mechanisms underlying the transition from SSCs to sperm are largely unknown.

Structural, mechanistic and inhibition studies on the histone lysine demethylases

open access: yes, 2009
Histone lysine demethylases comprise an important family of epigenetic regulatory enzymes. They catalyse the demethylation of tri-, di- and monomethylated lysine residues on histone H3, thus contributing to either silencing or activation of chromatin ...

Inhibitors of Jumonji-C domain-containing histone demethylases

open access: yes
[Inicio] Histone methylation represents an epigenetic modification that plays important roles not only for the transcriptional regulation but also for the preservation of genomic stability in eukaryotes. The methylation status of specific lysines is kept

Two Conserved Histone Demethylases Regulate Mitochondrial Stress-Induced Longevity [PDF]

open access: yes, 2016
Across eukaryotic species, mild mitochondrial stress can have beneficial effects on the lifespan of organisms. Mitochondrial dysfunction activates an unfolded protein response (UPR(mt)), a stress signaling mechanism designed to ensure mitochondrial ...

Molecular Mechanism of the IRF1/NFE2L1‐DT/ALKBH5/Cx43 Axis in Radiation‐Induced Injury in Vascular Endothelial Cells Through Pyroptosis

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Radiotherapy effectively eradicates tumor cells but can also trigger pyroptotic damage in vascular endothelial cells. This study investigates the role of interferon regulatory factor 1 (IRF1) in radiation‐induced endothelial injury, aiming to provide mechanistic insights for optimizing radiotherapy.

ZFP36L1 Enhances Microglial Ferroptosis in Ischemic Stroke by Reducing FTO‐Mediated N6‐Methyladenosine Demethylation of ACSL1 mRNA

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Microglia play an important role in ischemic stroke (IS). However, the molecular regulatory mechanisms underlying microglial ferroptosis in IS remain incompletely understood. In this study, blood samples were collected from 20 IS patients and 15 healthy volunteers.
