Extracellular vesicles in pharmacology: Innovations in drug delivery and therapeutic applications in cancer

British Journal of Pharmacology, EarlyView.
Extracellular vesicles (EVs) are a diverse population of membrane nanoparticles secreted by nearly all cell types, playing a key role in intercellular communication by transferring bioactive macromolecular cargo. In cancer, EVs shape both the local tumour microenvironment and distant premetastatic niches.

Genetic Evolution in BRCA1‐Associated Breast Cancer Reveals Early Driver Mutations Shaping Tumor Features and Prognosis

Cancer Science, EarlyView.
Multi‐region sequencing of 57 BRCA1‐associated breast cancers identified TP53 as the dominant initial driver, defining a triple‐negative subgroup with biallelic BRCA1 loss and elevated genomic instability. TP53 truncating mutations were enriched in BRCA1 carriers and linked to reduced HRD, EMT activation, and a trend toward worse survival.

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 ...

tRNA‐Derived Small RNAs in Digestive Cancers: From Translational Regulation to Immune and Extracellular Communication

Cancer Science, EarlyView.
tRNA‐derived small RNAs (tsRNAs) function in digestive cancers across three scales: intracellular translational and metabolic control, extracellular vesicle–mediated immune remodeling, and systemic and host–microbe communication. This review organizes these mechanisms by evidence strength, from well‐established intracellular roles to emerging ...

Advances in Spatial Heterogeneity and Cellular Localization Specificity of Intratumoral Bacteria

Cancer Science, EarlyView.
Spatial localization of intratumoral bacteria governs their functional roles in tumor progression, metastasis, and treatment responses, with guiding significance for clinical management, as reviewed across three spatial paradigms. ABSTRACT Bacteria in tumors are increasingly recognized to be a part of the tumor microenvironment and their biological ...

Merkel Cell Carcinoma With Divergent Differentiation—Or Something Else? A Triphasic Cutaneous Carcinoma With Lineage Plasticity

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Merkel cell carcinoma (MCC) is a rare, aggressive cutaneous neuroendocrine carcinoma that typically arises in sun‐exposed skin of older or immunosuppressed patients. Combined or collision tumors involving MCC and other cutaneous malignancies are uncommon, and tumors exhibiting more than two distinct malignant phenotypes are exceptionally rare.

CD36‐mediated lipid rewiring in the metabolic adaptation of tumour ecosystems

The FEBS Journal, EarlyView.
Nutrient deprivation drives a lipid‐centric shift in tumour metabolic symbiosis and signalling network. CD36 functions as a bidirectional bridge, transferring fatty acids from stromal donors (adipocytes, CAFs) to the ecosystem tumour‐ and microenvironment‐dependently.

Long‐term outcome of high‐grade encapsulated papillary carcinoma of the breast: implications for staging and management

Histopathology, EarlyView.
In the original study by Rakha et al., the authors proposed that high‐grade EPC should be considered within an invasive framework regardless of hormone receptor status. In the present study, we adopted a more selective definition of EPC‐A, restricted to tumours showing more adverse features, including high‐grade morphology together with triple‐negative
