Brain metastasis‐associated fibroblasts shape the tumour microenvironment to enhance cancer cell invasion

Brain Pathology, EarlyView.
Brain metastasis‐associated fibroblasts are active stromal components of the metastatic niche characterised by extracellular matrix remodelling and production of pro‐migratory mediators. They promote monocyte and cancer cell migration and enhance cancer cell invasion while having no growth‐promoting effect on cancer cells.

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 ...

Macrophage Lipid Homeostasis Drives IVDD via a Senescence‐Dependent Impairment of Efferocytosis

Cell Proliferation, EarlyView.
Intervertebral disc degeneration (IVDD) has been a leading cause of low back pain and lacks disease‐modifying therapies. Although dysregulated disc lipid metabolism is implicated, its impact on the immune microenvironment, particularly macrophages, remains unknown.

Characterization of extracellular α-galactosidase produced by Streptomyces sp. YB-4

, 2002
A strain YB-4 producing the extracellular α-galactosidase was isolated from soil, and has been identified as Streptomyces sp. on the basis of its cultural, morphological and physiological properties. The partially purified α-galactosidase was most active

Olfactory Tuft Cells Are Critical to Basal Inflammation, Innate Immune Response to Viral Infection, and Modulation of Quiescent Stem Cell Activation, Proliferation and Differentiation

Cell Proliferation, EarlyView.
Olfactory tuft cells communicate with other mucosal cells in maintaining olfactory epithelial immunity and sensory function. Disruption of tuft cell signalling pathways causes a skewed immune response, leading to heightened inflammation and increased activation of the quiescent stem cells, which are further exacerbated by viral infection.

SGLT2 Inhibitors and Cardiovascular Outcomes in Patients With Fabry Disease: Observations From a Federated Research Network

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Background and Aim Fabry disease (FD) is frequently complicated by renal impairment and cardiovascular events; however, evidence on sodium–glucose cotransporter‐2 inhibitors (SGLT2i) in this population is scarce. Accordingly, we assessed the association between SGLT2i exposure and cardiovascular outcomes in adults with FD. Methods We conducted

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.

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.
