Digital spatial profiling of human parathyroid tumors reveals cellular and molecular alterations linked to vitamin D deficiency
Primary hyperparathyroidism (PHPT) is a common endocrine neoplastic disorder characterized by disrupted calcium homeostasis secondary to inappropriately elevated parathyroid hormone (PTH) secretion. Low levels of serum 25-hydroxyvitamin D (25OHD) are…

Phase 2 Trial of Stereotactic Ablative Radiotherapy for Patients with Primary Renal Cancer
Background: Most renal cell carcinomas (RCCs) are localized and managed by active surveillance, surgery, or minimally invasive techniques. Stereotactic ablative radiation (SAbR) may provide an innovative non-invasive alternative although prospective…

MULTIPLATFORM ANALYSIS OF INTRATUMORAL PTEN HETEROGENEITY IN MELANOMA
Loss of protein expression of the tumor suppressor PTEN is associated with increased cancer aggressiveness, decreased tumor immune infiltration, and resistance to immune and targeted therapies in melanoma. We assessed…

Spatial multi-omics revealed the impact of tumor ecosystem heterogeneity on immunotherapy efficacy in patients with advanced non-small cell lung cancer treated with bispecific antibody
Background: Immunotherapy for malignant tumors has made great progress, but many patients do not benefit from it. The complex intratumoral heterogeneity (ITH) hindered the in-depth exploration of immunotherapy. Conventional bulk…

Angiogenesis regulators S100A4, SPARC and SPP1 correlate with macrophage infiltration and are prognostic biomarkers in colon and rectal cancers
Introduction: Increasing evidence suggests that it is necessary to find effective and robust clinically validated prognostic biomarkers that can identify “high-risk” colorectal cancer (CRC) patients. Currently, available prognostic factors largely…

Spatial transcriptomics analysis of zone-dependent hepatic ischemia-reperfusion injury murine model
Hepatic ischemia-reperfusion (I/R) injury is a common complication in liver transplantation. The connection between I/R-induced injury response and liver heterogeneity has yet to be fully understood. In this study, we…

Spatially restricted tumour-associated and host-associated immune drivers correlate with the recurrence sites of pancreatic cancer
Objective: Most patients with pancreatic ductal adenocarcinoma (PDAC) will experience recurrence after resection. Here, we investigate spatially organised immune determinants of PDAC recurrence. Design: PDACs (n=284; discovery cohort) were classified…

The KRAS-Mutant Consensus Molecular Subtype 3 Reveals an Immunosuppressive Tumor Microenvironment in Colorectal Cancer
Simple Summary: The poor prognosis outcome of patients with KRAS mutations (KRASmut) was correlated with an immunosuppressive tumor microenvironment (TME). At the gene expression level and pathway analysis, KRASmut tumor…

Spatial and molecular profiling of the mononuclear phagocyte network in Classic Hodgkin lymphoma
Classic Hodgkin lymphoma (cHL) has a rich immune infiltrate, which is an intrinsic component of the neoplastic process. Malignant Hodgkin Reed-Sternberg cells (HRSC) create an immunosuppressive microenvironment by the expression…

Spatiotemporal local and abscopal cell death and immune responses to histotripsy focused ultrasound tumor ablation
Introduction: Histotripsy is a novel focused ultrasound tumor ablation modality with potent immunostimulatory effects. Methods: To measure the spatiotemporal kinetics of local andabscopal responses to histotripsy, C57BL/6 mice bearing bilateral…

Multiplexed 3D atlas of state transitions and immune interaction in colorectal cancer
Advanced solid cancers are complex assemblies of tumor, immune, and stromal cells characterized by high intratumoral variation. We use highly multiplexed tissue imaging, 3D reconstruction, spatial statistics, and machine learning…

Highly Multiplexed Spatially Resolved Proteomic and Transcriptional Profiling of the Glioblastoma Microenvironment Using Archived Formalin-Fixed Paraffin-Embedded Specimens
Glioblastoma is a heterogeneous tumor for which effective treatment options are limited and often insufficient. Few studies have examined the intratumoral transcriptional and proteomic heterogeneity of the glioblastoma microenvironment to…
