Adipocyte‐Derived Palmitic Acid Promotes Breast Cancer Malignancy via ZDHHC15‐Mediated S‐Palmitoylation of PPARγ

Cancer Science, EarlyView.
Adipocyte‐derived palmitic acid induces ZDHHC15‐mediated PPARγ S‐palmitoylation at Cys159, triggering its proteasomal degradation and promoting breast cancer malignancy with rosiglitazone resistance. Inhibition of PPARγ S‐palmitoylation by 2‐bromopalmitate suppresses breast cancer progression and synergistically enhances rosiglitazone efficacy ...

High Uric Acid Promotes Stem Leydig Cell Senescence by CCDC90B Mediates Mitochondrial Quality Control Imbalance

Cell Proliferation, EarlyView.
In hyperuricemia, uric acid inhibits CCDC90B ubiquitination degradation by binding to it. Excessive CCDC90B induces mitochondrial calcium overload, leading to mitochondrial quality control imbalance and ultimately resulting in SLC senescence and decreased testosterone levels.

The E‐cadherin‐Wnt‐mir‐994 Axis Repurposes a Cadherin Switch for Niche Robustness and Germline Stem Cell Maintenance

Cell Proliferation, EarlyView.
In the Drosophila ovarian niche, an E‐cadherin‐to‐N‐cadherin switch, mediated by Wnt‐mir‐994 signalling, is repurposed to ensure niche resilience. This compensatory mechanism maintains niche integrity and stem cell support upon E‐cadherin loss, revealing a robustness circuit.

Junctional Adhesion Molecule‐A (JAM‐A) Associates With High‐Risk Disease in Multiple Myeloma Patients and a Structure‐Based Rationally‐Designed Peptide Inhibitor Attenuates Tumorigenic Features In Vitro and In Vivo

European Journal of Haematology, EarlyView.
ABSTRACT Multiple myeloma (MM) is an incurable malignancy of terminally‐differentiated plasma cells that represents a major clinical challenge despite unprecedented therapeutic advances, particularly for patients with cytogenetically‐defined high‐risk MM (HR‐MM).

RAB4A acts as a negative feedback regulator of extracellular vesicle secretion during TGF‐β signaling

The FEBS Journal, EarlyView.
TGF‐β signaling regulates extracellular vesicle (EV) release in cancer cells by modulating the expression and activity of genes associated with EV biogenesis. The TGF‐β‐induced upregulation of RAB4A expression facilitates fast endosomal recycling, a process that limits the fusion of multivesicular bodies with the plasma membrane and EV secretion. Hence,

Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

The FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

Molecular dynamics simulations elucidate the misfolding mechanisms of secretion‐defective pancreatic lipase variants

The FEBS Journal, EarlyView.
Misfolding mutations in pancreatic lipase have been identified as potential contributors of chronic pancreatitis, an inflammatory disease of the human pancreas. Here, we describe the effect of these misfolding mutations on pancreatic lipase structure using molecular dynamics simulations and structural modeling.

Contribution of endosomal proteins EHD1 and EHD4 to the HIV‐1 replication cycle

The FEBS Journal, EarlyView.
EHD1 and EHD4, two key trafficking proteins, regulate multiple stages of HIV‐1 infection: In producer cells, they help produce fully infectious virus particles, regulate Envelope protein incorporation in a cell‐type‐dependent manner, and limit the accumulation of antiviral IFITM proteins in virions.

Structural insights into xyloglucan recognition by an ABC transporter from a Gram‐positive, thermophilic bacterium

The FEBS Journal, EarlyView.
Athe_2052 is an ABC transporter substrate‐binding protein that recognizes xyloglucan heptasaccharide (XXXG), a soluble breakdown product of plant xyloglucan. The crystal structure of Athe_2052, together with binding assays and computational modeling, shows how XXXG is recognized by this sugar transporter.

Bakuchiol: From structural mimicry to systems‐level skin biology

International Journal of Cosmetic Science, EarlyView.
Convergent outcomes, divergent mechanisms: bakuchiol vs. retinol. Bakuchiol exhibits functional convergence with retinol in improving extracellular matrix integrity, epidermal differentiation and barrier function, while operating through distinct mechanisms.
