Epirubicin Alters Pancreatic Autophagy and Insulin Synthesis Through a Zinc‐Dependent Mechanism

Journal of Applied Toxicology, EarlyView.
ABSTRACT Epirubicin (EPI) can cause metabolic side effects, including chemotherapy‐related diabetes, partly through oxidative stress that disrupts zinc (Zn) homeostasis and impairs autophagy. This study investigated the effects of EPI on Zn regulation and autophagy in the pancreas, as well as the modulatory role of N‐acetylcysteine (NAC). Rats received

Alterations in MicroRNA and Cytokine Expressions in Placental and Amniotic Tissues of COVID‐19 Affected Pregnant Women

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Since 2019, coronavirus disease 2019 (COVID‐19) has been associated with increased risks of preterm birth and placental complications. We prospectively investigated alterations in microRNAs (miRNAs) and cytokines in placental and amniotic tissues from pregnant women with and without COVID‐19 to evaluate the infection's impact on pregnancy ...

WDR72 Drives Esophageal Squamous Cell Carcinoma Progression by Inhibiting Autophagy via the PI3K/Akt/mTOR Pathway

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Esophageal squamous cell carcinoma (ESCC) is an aggressive malignancy with a high rate of recurrence and metastasis, necessitating the identification of novel therapeutic targets. WD repeat‐containing protein 72 (WDR72) has been linked to various cancers, but its specific biological function and underlying mechanism in ESCC remain largely ...

Structural Insights Into the Function of Leishmania major Adenylosuccinate Lyase

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT One of several intriguing aspects of kinetoplastid biochemistry is the complete dependence on host purines and purine recycling due to the lack of a de novo purine biosynthesis pathway. Adenylosuccinate lyase (ASL, EC 4.3.2.2) is a key enzyme in the purine synthesis pathway responsible for the conversion of adenylosuccinate into adenosine ...

Nanodisc single-molecule pulldown to study lipid-protein interactions

Journal of Lipid Research
Beyond serving structural roles in the cell membrane, many phospholipids, including phosphatidylinositol phosphates (PIPs), are key signaling molecules that regulate a myriad of cellular processes.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Synthesis of deuterated phosphatidylinositol phosphates

, 2016
Phosphatidylinositol phosphates (PtdInsPn) are intracellular signalling molecules that are important in many key biological processes, in particular Ca2+ signalling pathways. Dysfunction of these processes has been implicated in numerous diseases including diabetes and many cancers.

Osmotic Remodeling of Extracellular Vesicles for Precision Nanomedicine

Small, EarlyView.
Hypotonic lysis in bidistilled water is used to remodel B lymphocyte–derived extracellular vesicles into cargo‐depleted, structurally preserved nanovesicles. The process reduces intraluminal proteins and nucleic acids, reshapes membrane composition, and enhances tumor‐cell uptake in vitro, while allowing proof‐of‐concept reloading with exogenous agents,

Structural and dynamic changes in P-Rex1 upon activation by PIP3 and inhibition by IP4

eLife
PIP3-dependent Rac exchanger 1 (P-Rex1) is abundantly expressed in neutrophils and plays central roles in chemotaxis and cancer metastasis by serving as a guanine-nucleotide exchange factor (GEF) for Rac.
