Intracellular oxygen metabolism during bovine oocyte and preimplantation embryo development
Scientific Reports, 2021 We report a novel method to profile intrcellular oxygen concentration (icO2) during in vitro mammalian oocyte and preimplantation embryo development using a commercially available multimodal phosphorescent nanosensor (MM2).

Alkyltriphenylphosphonium Binding to Cardiolipin Triggers Oncosis in Cancer Cells
Advanced Science, EarlyView.Alkyltriphenylphosphonium, exemplified by TPP+‐C14, preferentially accumulates in mitochondria and selectively binds to cardiolipin, a key phospholipid of the inner mitochondrial membrane, causing loss of mitochondrial membrane potential, severe cellular ATP depletion, and calcium imbalance.

Advanced Science, EarlyView.Aged HSF1 muscle‐specific knockout mice show deteriorated muscle atrophy and metabolic dysfunction, while active HSF1 overexpression improves muscle function via activating SIRT3 to deacetylate both PGC1α1 and PGC1α4, which boosts mitochondrial function and muscle hypertrophy in a fiber‐type specific manner, and induces FNDC5/Irisin for tissue ...

An unexpected protein interaction promotes drug resistance in leukemia
Nature Communications, 2017 ABCC4 is a chemotherapeutic drug exporter highly expressed in acute myeloid leukemia. Here, the authors demonstrate that MPP1 anchors ABCC4 to the outer cell membrane mediating drug resistance in leukemic cells and identify antimycin A as a chemical ...

A Mussel‐Inspired Bioadhesive Patch to Selectively Kill Glioblastoma Cells
Advanced Science, EarlyView.An innovative mussel‐inspired bioadhesive patch has been developed for post‐surgical glioblastoma treatment. The patch, which adheres strongly in biological environments, releases a localized treatment. This treatment, acting via reactive oxygen species, shows specific toxicity to glioblastoma cells.

Advanced Science, EarlyView.Dietary habits play a key role in chronic diseases, and higher annual consumption of fruit and vegetable may lower risk of dementia. Artificial intelligence predicts the lipid‐like compound α‐Amyrin (αA) from plants with edible peels as a drug candidate against Alzheimer's disease.

Antimycin A, but not antimycin A3 or myxothiazol, directly suppresses photosystem II activity
Bioscience, Biotechnology, and BiochemistryAbstract Antimycin A (AA) is a widely used inhibitor to study photosynthesis and respiration. In photosynthesis, it is commonly used to inhibit a pathway of cyclic electron flow around photosystem I (CEF-PSI), but has also been reported to affect photosystem II (PSII), not involved in CEF-PSI.
