REVIEW
- Renal disease pathophysiology and treatment: contributions from the rat
Summary: This Review highlights the key role that the rat continues to play in improving our understanding of the etiologies of renal pathologies, and how these insights have opened up new therapeutic avenues.
RESEARCH ARTICLES
- Heterotypic mouse models of canine osteosarcoma recapitulate tumor heterogeneity and biological behavior
Editors' choice: We developed a system that recapitulates the heterogeneous biological behavior of bone cancer in mouse models and describe novel methods to study tumor–stromal interactions in these models.
- Whole-genome sequence, SNP chips and pedigree structure: building demographic profiles in domestic dog breeds to optimize genetic-trait mapping
Summary: Successful application of whole-genome sequencing and genome-wide association studies for identifying both loci and mutations in canines is influenced by breed structure and demography, motivating researchers to generate breed-specific strategies for canine genetic studies.
- Lurbinectedin induces depletion of tumor-associated macrophages, an essential component of its in vivo synergism with gemcitabine, in pancreatic adenocarcinoma mouse models
Summary: Lurbinectedin-gemcitabine synergism in PDA models involves lurbinectedin-induced tumor macrophage depletion, triggering CDA downregulation and enhanced DNA damage, supporting the use of this combination to treat macrophage-infiltrated pancreatic tumors.
- Helicobacter pylori VacA, acting through receptor protein tyrosine phosphatase α, is crucial for CagA phosphorylation in human duodenum carcinoma cell line AZ-521
Summary: The authors show a newly identified role of VacA in Helicobacter pylori infection through induction of tyrosine phosphorylation of CagA acting through the VacA receptor RPTPα.
- Deregulated expression of HDAC9 in B cells promotes development of lymphoproliferative disease and lymphoma in mice
Summary: This study demonstrates that aberrant expression of HDAC9 in B cells promotes development of lymphoproliferative disease and lymphoma through altering expression of genes involved in the cell cycle and survival, and modulating the activity of key B-lineage factors such as BCL6 and p53.
- Microglia activation in a pediatric rabbit model of tuberculous meningitis
Summary: A clinically relevant novel rabbit model provides robust microglial activation and neurological deficits as seen in children with pediatric central nervous system tuberculosis.
- Recovery of erectile function comparing autologous nerve grafts, unseeded conduits, Schwann-cell-seeded guidance tubes and GDNF-overexpressing Schwann cell grafts
Summary: Schwann-cell-seeded scaffolds and GDNF-overexpressing Schwann cell grafts are superior to unseeded tubes and autologous nerve grafts for the repair of erectile nerve gaps following nerve excision in rats.

preLights – HSP110 dependent HSP70 disaggregation machinery mediates prion-like propagation of amyloidogenic proteins in metazoa
Highlighted by Tessa Sinnige, a recent preprint from Carmen Nussbaum-Krammer and co-workers shows that Hsp110 activity protects against amorphous protein aggregation but promotes amyloid aggregation and toxicity in C. elegans models.
