Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Establishing an assay to evaluate d‐amino acid oxidase enzyme kinetics and inhibition using WST‐8 redox dye

FEBS Open Bio, EarlyView.
This study investigated a novel WST‐8‐based assay for evaluating d‐Amino acid oxidase (DAO) inhibitors. We confirmed its effectiveness using known inhibitors and found that uremic toxins possess relatively weak inhibitory activity compared to existing drugs.

A novel CHCHD10 mutation implicates a Mia40‐dependent mitochondrial import deficit in ALS

EMBO Molecular Medicine, 2018
CHCHD10 mutations are linked to amyotrophic lateral sclerosis, but their mode of action is unclear. In a 29‐year‐old patient with rapid disease progression, we discovered a novel mutation (Q108P) in a conserved residue within the coiled‐coil‐helix‐coiled‐

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

FEBS Open Bio, EarlyView.
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Mitochondrial complex I inhibition enhances astrocyte responsiveness to pro-inflammatory stimuli

Scientific Reports
Inhibition of the mitochondrial oxidative phosphorylation (OXPHOS) system can lead to metabolic disorders and neurodegenerative diseases. In primary mitochondrial disorders, reactive astrocytes often accompany neuronal degeneration and may contribute to ...

Highly efficient intercellular spreading of protein misfolding mediated by viral ligand-receptor interactions

Nature Communications, 2021
Pathologic protein aggregates associated with neurodegenerative diseases have the ability to transmit to unaffected cells via extracellular vesicles or direct cell-to-cell contact. Here, Liu et al.

Blood‐based proteomic profiling reveals context‐dependent changes in BCL2‐associated signaling during taxane therapy in breast cancer patients

FEBS Open Bio, EarlyView.
Chemotherapy side effects significantly impact cancer survivors' quality of life. Using protein levels in blood samples from breast cancer patients before and after 12 weeks of taxane treatment, we detected treatment‐dependent changes in calcium signaling and aging pathways associated with cancer recurrence.

Chr:17q21.31 locus risk haplotype H1 susceptibility to ferroptosis is mediated by endolysosomal pathway

Cell Death and Disease
Human chr:17q21.31 locus is a complex genomic region of high linkage disequilibrium with two main haplotypes, named H1 and H2. The H1 haplotype is genetically associated with a wide spectrum of neurodegenerative diseases (NDs), including tauopathies and ...

Identifying future research priorities for diversity-sensitive psychosocial interventions to manage dementia-related symptoms (GenderDem): protocol for a priority setting partnership study

BMJ Open
Introduction Gender, sex and ethnicity-sensitive approaches to psychosocial interventions for behavioural and psychological symptoms of dementia have been under-represented in the literature.
