Lack of TRIC‐B dysregulates cytoskeleton assembly, trapping β‐catenin at osteoblast adhesion sites

The FEBS Journal, Volume 292, Issue 8, Page 1920-1933, April 2025.
In the presence of TRIC‐B, cytosolic Ca2+ activates protein kinase C, which phosphorylates the actin‐binding proteins fascin and MARCKS, leading to proper cytoskeletal organization. This allows an appropriate β‐catenin distribution inside the cell and its translocation into the nucleus, where it stimulates the transcription of osteoblastogenic genes ...

Transcriptomic signatures and network‐based methods uncover new senescent cell anti‐apoptotic pathways and senolytics

The FEBS Journal, Volume 292, Issue 8, Page 1950-1971, April 2025.
This study identifies new senescent cell antiapoptotic pathways (SCAPs) by analyzing transcriptomic signatures and co‐expression networks. We uncover novel antiapoptotic pathways, called SCAPs, and propose potential senolytic drugs, including Fluorouracil, which targets key SCAPs.

Activating AMPK improves pathological phenotypes due to mtDNA depletion

The FEBS Journal, Volume 292, Issue 9, Page 2359-2380, May 2025.
In a cellular model of mitochondrial disease characterized by progressive mitochondrial DNA (mtDNA) depletion, we found that advancing mitochondrial dysfunction triggers the early and specific activation of the mitochondria‐associated pool of AMP‐activated protein kinase (AMPK), a master regulator of energy homeostasis.

Mammalian TatD DNase domain containing 1 (TATDN1) is a proteostasis‐responsive gene with roles in ventricular structure and neuromuscular function

The FEBS Journal, EarlyView.
Twin‐arginine translocation D (TatD) homologs are found across all kingdoms, with debated roles in DNA degradation and protein quality control in unicellular organisms. We characterize TATDN1, the mammalian TatD orthologue, as a proteostatic stress‐responsive cytosolic protein dispensable for DNA degradation.

ZNF224 enhances the oncogenic function of p21 via p53 and AKT pathways in melanoma

The FEBS Journal, EarlyView.
KRAB zinc finger protein ZNF224 acts as an oncogenic factor in melanoma cells, enhancing p21 cytosolic retention and impairing nuclear p21 cytostatic activity through stimulation of the AKT pathway. Furthermore, ZNF224 regulates transcriptional expression levels of p21 via p53.

Pathological significance of intranuclear structures in liver biopsy samples

Hepatology Research, EarlyView.
Schematic representation of the potential significance of three distinct nuclear structures. Glycogenated nuclei reflects excessive glycogen accumulation in the hepatocytes. Nucleoplasmic lipid droplets form in the nucleus during hepatocyte injury. Cytoplasmic lipid droplets in the nucleoplasmic reticulum are suppressed when there is excessive fat ...

Arrhythmogenic Cardiomyopathy: Towards Genotype Based Diagnoses and Management

Journal of Cardiovascular Electrophysiology, EarlyView.
To improve arrhythmogenic cardiomyopathy (ACM) patient care four pillars of ACM research are necessary. The first pillar to improve ACM is cohort studies in which the genotype‐specific natural history of disease is described, and subsequently genotype‐specific risk calculators can be developed, such as the DSP and PLN risk calculators.

Photostimulation increases food intake, agouti‐related protein (AGRP) and type II iodothyronine deiodinase (DIO2) gene expression in the medio‐basal hypothalamus of Gambel's White‐crowned Sparrow

Journal of Neuroendocrinology, EarlyView.
Abstract Before migration, birds express hyperphagia leading to deposition of fuel in support of long‐distance flight. Long days in spring stimulate a photoperiodic neuroendocrine cascade leading to heightened food intake. A major component of the response of the reproductive system to increased daylength in birds is the local conversion of thyroxine ...

Achilles tenocytes from diabetic and non diabetic donors exposed to hyperglycemia respond differentially to inflammatory stimuli and stretch

Journal of Anatomy, EarlyView.
Scheme depicting the experimental set up of the study. Achilles tendons and tenocytes were isolated from heterozygous (fa/+, non diabetic: non DMT2) and homozygous (fa/fa, diabetic: DMT2) Zucker Diabetic Fatty (ZDF) rats. Tendon degeneration, collagen type 1 alpha 1 chain (COL1A1) and alpha smooth muscle actin (αSMA) expression was determined in rat ...

Unveiling Propriety, Validity and Consensus: A Multi‐level Examination of Legitimacy Following the Global Financial Crisis

Journal of Management Studies, EarlyView.
Abstract Previous work on legitimacy has conceptualized its multi‐level nature, encompassing individual‐level propriety and collective‐level validity. Recently, scholars have introduced the construct of consensus, the degree to which evaluators agree in terms of their propriety beliefs.
