Inhibition of p53-MDM2 binding reduces senescent cell abundance and improves the adaptive responses of skeletal muscle from aged mice
Skeletal muscle adaptation to external stimuli, such as regeneration following injury and hypertrophy in response to resistance exercise, are blunted with advanced age. The accumulation of senescent cells, along with…

Spatial Distribution Of Immune Cells Drives Resistance To Neoadjuvant Chemotherapy In Triple-Negative Breast Cancer
Neoadjuvant chemotherapy (NAC) alone or combined with target therapies represents the standard of care for localized triple-negative breast cancer (TNBC). However, only a fraction of patients have a response, necessitating…

Targeting stroma and tumor, silencing galectin 1 treats orthotopic mouse hepatocellular carcinoma
This study examines inhibiting galectin 1 (Gal1) as a treatment option for hepatocellular carcinoma (HCC). Gal1 has immunosuppressive and cancer-promoting roles. Our data showed that Gal1 was highly expressed in…

Digital Spatial Profiling Identifies the Tumor Periphery as a Highly Active Biological Niche in Clear Cell Renal Cell Carcinoma
Simple Summary: Clear cell renal cell carcinoma is characterized by a high degree of genomic intratumoral heterogeneity. The extent of spatial and functional heterogeneity, however, is much less understood. In…

Evaluation of antibody-based single cell type imaging techniques coupled to multiplexed imaging of N-glycans and collagen peptides by matrix-assisted laser desorption/ionization mass spectrometry imaging
The integration of matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) with single cell spatial omics methods allows for a comprehensive investigation of single cell spatial information and matrisomal N-glycan and…

Expression of IDO1 in tumor microenvironment significantly predicts the risk of recurrence/distant metastasis for patients with esophageal squamous cell carcinoma
In this study, we aimed to explore immune markers predicting locoregional recurrence/distant metastasis (R/M) for patients with esophageal squamous cell carcinoma (ESCC) post-surgical intervention by using a novel high-throughput spatial…

Stress Keratin 17 Is a Predictive Biomarker Inversely Associated with Response to Immune Check-Point Blockade in Head and Neck Squamous Cell Carcinomas and Beyond
Simple Summary: Between 15 and 35% of head and neck cancer patients respond to immune check-point blockade therapy (ICB), and some may experience potentially life-threatening adverse events. Biomarkers that can…

Organ-specific immunity: A tissue analysis framework for investigating local immune responses to SARS-CoV-2
Local immune activation at mucosal surfaces, mediated by mucosal lymphoid tissues, is vital for effective immune responses against pathogens. While pathogens like severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can…

Spatial proteomics of hippocampal subfield-specific pathology in Alzheimer’s disease and primary age-related tauopathy
INTRODUCTION: Alzheimer's disease (AD) and primary age-related tauopathy (PART) both harbor 3R/4R hyperphosphorylated-tau (p-tau)-positive neurofibrillary tangles (NFTs) but differ in the spatial p-tau development in the hippocampus. METHODS: Using Nanostring…

Digital spatial profiling of melanoma shows CD95 expression in immune cells is associated with resistance to immunotherapy
Although immune checkpoint inhibitor (ICI) therapy has dramatically improved outcome for metastatic melanoma patients, many patients do not benefit. Since adverse events may be severe, biomarkers for resistance would be…

Molecular portraits of patients with intrahepatic cholangiocarcinoma who diverge as rapid progressors or long survivors on chemotherapy
Objective: Cytotoxic agents are the cornerstone of treatment for patients with advanced intrahepatic cholangiocarcinoma (iCCA), despite heterogeneous benefit. We hypothesised that the pretreatment molecular profiles of diagnostic biopsies can predict…

Peritumoral immune suppressive mechanisms impede intratumoral lymphocyte infiltration into CRC liver versus lung metastases
Microsatellite stable (MSS) colorectal cancer (CRC) patients with liver metastases are resistant to immune checkpoint inhibitor (ICI) therapy, while about one-third of CRC patients without liver metastases, particularly those with…
