Lipid Nanoparticles Delivering ClpP‐mRNA Suppress Pyroptosis and Senescence in Intervertebral Disc Degeneration via mTOR/BNIP3‐Activated Mitophagy

Rare Metals, EarlyView.
ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and

Upconversion Photoluminescence to Monitor Local Heat Release During Femtosecond Direct Laser Writing of Bioinks In Situ

Small Methods, EarlyView.
Upconversion nanoparticle photoluminescence was used to quantify heat burden during femtosecond direct laser writing of bioinks in real time. Transient temperature spikes above 120–140°C demonstrate the need for a stringent process optimization, and fast 20 µm/s scan speeds were established to maintain physiological conditions.

Comparative Analysis of Heat Exposure‐Induced Molecular Changes in Two Turtle Species with Contrasting Thermal Adaptations

Integrative Zoology, EarlyView.
Protein processing in the endoplasmic reticulum is highlighted in response to heat stress in Platysternon megacephalum. Under heat stress, the up‐regulation of genes such as CHOP in protein processing in the endoplasmic reticulum pathway, along with the suppression of energy and lipid metabolism and the up‐regulation of JARID2 expression, leads to ...

Folding, misfolding, and regulation of intracellular traffic of G protein‐coupled receptors involved in the hypothalamic–pituitary–gonadal axis

Andrology, EarlyView.
Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.

The depletion of serine beta‐lactamase‐like protein (LACTB) ameliorates metabolic dysfunction–associated steatotic liver disease by reducing ubiquitin‐mediated degradation of carnitine palmitoyltransferase 2

Diabetes, Obesity and Metabolism, EarlyView.
Abstract Aims Metabolic dysfunction–associated steatotic liver disease (MASLD) represents one of the most common chronic liver disorders worldwide, and its incidence continues to rise each year. Serine β‐lactamase‐like protein (LACTB) is a serine protease that plays a crucial role in lipid metabolism and hepatocellular carcinoma, but its function in ...

Differential regulation of translational stress responses by herpesvirus ubiquitin deconjugases

The FEBS Journal, EarlyView.
Translating viral mRNAs is challenging due to structural features that may slow translation or induce ribosome stalling. The viral ubiquitin deconjugases encoded by human pathogenic herpesviruses regulate the cellular response to ribosomal stress by inhibiting various branches of the Ribosomal Quality Control (RQC) and activating Ribosomal Stress ...

TbTim20 facilitates protein import at a low membrane potential in trypanosomes lacking the mitochondrial genome

The FEBS Journal, EarlyView.
Protein import into mitochondria relies on TIM complexes and the membrane potential. Trypanosoma brucei has a unique TIM complex, and the role of one subunit, TbTim20, has remained unclear. Here, we show that TbTim20 is essential in cells lacking mitochondrial DNA. The importance of TbTim20 increases as the membrane potential decreases.

E3 ligase Praja1 mediates ubiquitination and degradation of microtubule‐associated protein tau

The FEBS Journal, EarlyView.
E3 ligase Praja1, but not its paralogue Praja2, recognizes and ubiquitinates tau protein for proteasomal degradation. This newly identified function of Praja1‐mediated tau degradation suggests its role in protein quality control, which may provide insights into the pathogenesis of tauopathies.
