A role for eIF5A in translational control of stress‐inducible proteins in multiple myeloma cell lines

Molecular Oncology, EarlyView.
Loss of eIF5A rewires thapsigargin‐mediated endoplasmic reticulum stress responses in multiple myeloma cells by selective translation of mRNA transcripts, consequently dampening thapsigargin‐induced unfolded protein response (UPR) activation and shifting the balance from induction of apoptosis toward cell survival and proliferation.

An HSP90 cochaperone Ids2 maintains the stability of mitochondrial DNA and ATP synthase

BMC Biology, 2021
Background Proteostasis unbalance and mitochondrial dysfunction are two hallmarks of aging. While the chaperone folds and activates its clients, it is the cochaperone that determines the specificity of the clients.

The multifaceted roles of lysosomes in cancer

Molecular Oncology, EarlyView.
Lysosomes support cancer cell adaptation by integrating macromolecule degradation and nutrient recycling with nutrient sensing, inter‐organelle communication and immune regulation. These interconnected functions can promote tumour growth, stress tolerance and therapy resistance, while also creating context‐dependent vulnerabilities that may be ...

Suboptimal mitochondrial activity facilitates nuclear heat shock responses for proteostasis and genome stability

, 2022
Thermal stress induces dynamic changes in nuclear proteins and relevant physiology as a part of the heat shock response (HSR). However, how the nuclear HSR is fine-tuned for cellular homeostasis remains elusive.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Blood RNA Biomarker Signatures for Early Diagnosis and Prognosis in Ischemic and Hemorrhagic Stroke: The IBIS‐CT1 Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate the expression of nine blood RNA biomarkers in a clinical trial based on genes previously identified in an experimental monkey model of stroke for diagnosis feasibility and prognostication. Methods IBIS‐CT1 was a prospective longitudinal study enrolling patients with ischemic stroke (IS) or intracerebral hemorrhage (ICH ...

Glial-derived mitochondrial signals affect neuronal proteostasis and aging

Science Advances, 2023
The nervous system plays a critical role in maintaining whole-organism homeostasis; neurons experiencing mitochondrial stress can coordinate the induction of protective cellular pathways, such as the mitochondrial unfolded protein response (UPR MT ), between tissues.

OAF Blocks SIAH1‐Mediated Degradation of SCPX, a Therapeutic Strategy for MASLD

Advanced Science, EarlyView.
This study shows OAF directly binds to SCPX and inhibits its interaction with the E3 ligase SIAH1, thereby protecting SCPX from ubiquitin‐dependent degradation and stabilizing its levels. This OAF‐SCPX axis represents a novel pathway in lipid homeostasis, highlighting OAF as a promising therapeutic candidate for MASLD.

Single‐Nucleus Atlas of Spinal Sarcopenia Patients Reveals Disruption of Quiescent and Regenerative Satellite Cell Niches in Fatty‐Infiltrated Muscle

Advanced Science, EarlyView.
Mechanisms of Fatty Infiltration and Muscle Degeneration. Clinical metadata identified intramuscular fat accumulation as an independent driver of muscle mass decline. Single‐nucleus RNA sequencing of spinal sarcopenia muscle revealed adipogenic reprogramming of fibro‐adipogenic progenitors, satellite‐cell niche disruption, and elevated levels of the ...

MAPA: A Semantic Network Framework for Functional Module Discovery and Interpretation in Multi‐Omics Data

Advanced Science, EarlyView.
MAPA transforms complex multi‐omics data into biologically coherent functional modules by integrating pathway information with molecular interaction networks. Retrieval‐augmented large language models then generate structured, literature‐informed interpretations.
