Clinical characteristics and outcome of a cohort of CLL patients with BTK T474 gatekeeper mutation
BTK T474 gatekeeper mutations confer resistance to both commercially approved covalent and non-covalent BTK inhibitors (BTKis) in chronic lymphocytic leukemia (CLL), yet their clinical implications remain poorly characterized. While pirtobrutinib was developed to overcome resista...

Understanding the tumor microenvironment has the potential to significantly advance precision oncology, but this effort has been hampered by the scarcity of consistent large data sets. Here, we introduce MOSAIC (Multi-Omics Spatial Atlas in Cancer), a multi-center clinical omics...

Head and neck cancer (HNC) comprises a heterogeneous group of malignancies with substantial variation in incidence, risk factors, and outcomes across populations. Existing studies are often limited by regional scope or lack integration of epidemiological, clinical, and molecular...

Importance Risk stratification in advanced mycosis fungoides and Sézary syndrome (MF/SS) remains suboptimal given that current TNMB (tumor, node, metastasis, blood) staging has limited prognostic value for clinically relevant outcomes. Objective To determine whether the Cutaneous...

Abstract Nanoparticle (NP)-based drug delivery has been explored to improve the therapeutic index of anticancer agents by enhancing tumor accumulation and reducing systemic toxicity. Among active targeting approaches, cluster of differentiation 44 (CD44) has attracted attention b...

Despite substantial treatment improvements, the 5-year survival rate for metastatic osteosarcoma (OS) is still as low as 20%. Immunocompetent genetic mouse models of OS have been introduced, enabling in vivo OS studies. Here, we present the ROCCIA mouse, a quintuple-mutant extens...

Background & Aims: Hepatocellular carcinoma (HCC) remains among the most lethal cancers worldwide, yet few tools exist to characterize HCC biology and stratify patient risk at the point of care. We developed TESERA (Tissue Encoded Subtype Elucidation and Risk Assessment), a compu...

ABSTRACT Introduction Sarcomas are rare malignancies that affect both adults and children. Surgical removal with negative histopathological margins is the foundation of sarcoma treatment. Failure to achieve negative margins puts patients at risk of local recurrence (LR). LR rates...

Metastatic breast cancer remains incurable, underscoring the need for novel therapeutic strategies. Epidemiological and preclinical evidence suggests statins suppress metastatic outgrowth, however the underlying mechanisms remain unclear. We employed high-resolution spatial trans...

Abstract Fungi have been detected within human tumors and shown to support tumor progression. A better understanding of how intratumoral fungi evade innate immunity, remodel the tumor microenvironment (TME), and promote tumorigenesis may provide insights into cancer pathogenesis...

Molecular basis of nick ligation in the nucleosome by DNA Ligase IIIα
Eukaryotic genomic DNA is packaged into chromatin through a fundamental repeating unit known as the nucleosome core particle. Within this chromatin context, genomic DNA is constantly exposed to endogenous and exogenous stress that result in the formation of DNA damage, which must...

Functionally active lymphoid aggregates correlate with improved prognosis in brain metastases
Abstract B cells and their cellular neighborhoods, i.e., lymphoid aggregates (LAs) and tertiary lymphoid structures (TLS), have not been extensively studied in melanoma brain metastases (BM) or lung adenocarcinoma (LUAD) BM, despite their prognostic value and role in immunotherap...

Primary BPH Stromal Cell Cultures Exhibit Heightened Androgen‐Responsiveness
ABSTRACT Background Benign prostatic hyperplasia (BPH) is the most common disease in aging males. BPH growth is androgen‐dependent, and it appears that androgens preferentially stimulate the growth of BPH as compared to normal prostate. The mechanism of preferential androgen stim...

Telomeres are highly susceptible to oxidative DNA damage, particularly 8-oxoguanine (8-oxoG), which is processed by glycosylase-initiated base excision repair (BER). OGG1 removes 8-oxoG opposite C, and MUTYH removes A misinserted opposite 8-oxoG to prevent mutations. While OGG1 h...

Decade-long persistence of CD19 CAR T cells in B cell lymphomas
Abstract Chimeric antigen receptor (CAR) T cell therapy induces durable remissions in lymphoid malignancies, yet the extent and biology of long-term CAR T cell persistence in B cell lymphoma remain unclear. Here we report the persistence and characteristics of 4-1BB-costimulated...

Subclinical rejection after liver transplantation precludes immunosuppression withdrawal despite normal clinical function. To better understand the immunobiology of early subclinical rejection, we performed longitudinal, multimodal immune profiling and single-cell RNA sequencing...

A dependency map enhanced with next-generation 3D cancer models
Despite advances in precision oncology, effective personalized treatments are still lacking for most patients with cancer1. The Cancer Dependency Map (DepMap) accelerates this field by systematically identifying cancer vulnerabilities in diverse preclinical models. Data from over...

Cancer immunotherapy has transformed cancer treatment, yet its efficacy remains limited by a “cold” tumor immune microenvironment (TIME) characterized by poor T cell infiltration. Induction of immunogenic cell death (ICD) improves T cell infiltration by promoting the release of T...
