Arsenite methyltransferase 3 is required for mitochondrial function and hepatic lipid metabolism
The FEBS Journal, EarlyView.AS3MT is a protein that helps the body process arsenic, a naturally occurring toxin found in water and soil. We discovered it also helps cells make and use energy properly. Without AS3MT, cells' mitochondria do not work well, leading to fatty liver and reduced activity. Increasing AS3MT in liver cells restores energy and protects against arsenic damage,

The FEBS Journal, EarlyView.We investigated the potential of iloperidone as an activator of Sigma‐1 receptor (S1R) neuroprotective function in juvenile Huntington's disease (jHD). We tested iloperidone on cortical neurons differentiated from patient‐derived iPSCs, demonstrating that it acts as a S1R agonist, decreasing apoptosis, huntingtin aggregation, and oxidative stress ...

RNF13 regulates the endolysosomal pathway through interaction with the small GTPase Arl8B
The FEBS Journal, EarlyView.The E3 ubiquitin ligase RNF13 functions as a regulatory scaffold, organizing Arl8B‐dependent complexes and tuning downstream signaling that controls endolysosomal organization and trafficking. In this model, wild‐type RNF13 associates with Arl8B on endolysosomes, whereas Arl8B (E22D/F55A) or RNF13 (L244A) variants weaken complex assembly, potentially ...

The FEBS Journal, EarlyView.Blocking protein quality control degradation by deleting the E3 ligases Ubr1 or San1 stabilizes many DHFR insertion and deletion variants that are otherwise partially unfolded. These hypomorphic variants regain folding at lower temperatures or upon methotrexate binding, revealing that PQC degradation can remove proteins that are still functionally ...

Physiological media and oxygen levels modulate cancer hallmarks in cultured breast cancer cells
The FEBS Journal, EarlyView.MCF7 breast cancer cells were cultured in standard conditions (18% O2 and DMEM) and physiological conditions (5% O2 and Plasmax, a medium modeled after the human plasma metabolome). A combined transcriptomic and proteomic approach was used to identify gene expression signatures at the mRNA and protein levels upstream of functional enrichment analyses ...

TOP1MT rs2293925 is an enhancer‐active regulatory SNP that shapes mitochondrial R‐loop dynamics
The FEBS Journal, EarlyView.This study shows how a common genetic variant of mitochondrial topoisomerase 1 (TOP1MT rs2293925) can influence mitochondrial gene regulation, DNA topology, and formation of noncanonical nucleic acid structures such as R‐loops. By linking this enhancer‐active variant to mitochondrial nucleic acid stress in cellular contexts relevant to amyotrophic ...
