Mapping immune activity in HPV-negative head and neck squamous cell carcinoma: a spatial multiomics analysis

Background
Head and neck squamous cell carcinoma (HNSCC) exhibits low response rates to immunotherapies, with only about 15–25% of patients responding to monotherapy and 30–45% to combination therapy. This limited effectiveness is attribut…

Ectopic expression of GDF15 in cancer-associated fibroblasts enhances melanoma immunosuppression via the GFRAL/RET cascade

Background
A key aspect of tumor biology is the involvement of cancer-associated fibroblasts (CAFs) in shaping the immunosuppressive microenvironment. However, the dynamic and complex key roles of CAFs in the melanoma immune microenvironment have not …

Intratumoral neutrophil-to-lymphocyte ratio is mirrored by circulating neutrophil-to-lymphocyte ratio in non-small cell lung cancer

Tumor-initiated emergency granulopoiesis results in expansion of the circulating neutrophil compartment and neutrophil recruitment into the tumor microenvironment (TME), which may in turn promote tumor progression. Although an elevated circulating neu…

Hypoxia upregulates the expression of PD-L1 via NPM1 in breast cancer

Background
A hypoxic microenvironment is the most frequent characteristic in tumor microenvironment. Programmed death-ligand 1 (PD-L1) is an important molecule and therapeutic target that mediates the immune response of tumor cells. Previous studies h…

Multiomics identifies tumor-intrinsic SREBP1 driving immune exclusion in hepatocellular carcinoma

Immune checkpoint inhibitors (ICI) have improved patient outcomes in hepatocellular carcinoma (HCC); however, most patients do not experience durable benefit. The non-T cell-inflamed tumor microenvironment, characterized by limited CD8+ T-cell infiltr…

IL-4-STAT6-induced high Siglec-G/10 expression aggravates the severe immune suppressive tumor microenvironment and impedes the efficacy of immunotherapy in head and neck squamous cell carcinoma

Background
Immune checkpoint blockade therapy has shown limited efficacy in head and neck squamous cell carcinoma (HNSCC). Sialic acid binding immunoglobulin-like lectin (Siglec)-15 has been identified as a novel immune evasion biomarker, while the ro…

Tumor-intrinsic TTLL12 drives resistance to cancer immunotherapy via modulating myeloid-derived suppressor cells

Background
The majority of patients treated with immunotherapy as a standalone therapy experience little to no benefits. Tubulin tyrosine ligase 12 (TTLL12), as a member of the tubulin tyrosine ligase protein family, is associated with the prognosis o…

Development and validation of the Immune Profile Score (IPS), a novel multiomic algorithmic assay for stratifying outcomes in a real-world cohort of patients with advanced solid cancer treated with immune checkpoint inhibitors

Background
Immune checkpoint inhibitors (ICIs) have transformed the oncology treatment landscape. Despite substantial improvements for some patients, the majority do not benefit from ICIs, indicating a need for predictive biomarkers to better inform t…

Super-high tumor mutational burden predicts complete remission following immunotherapy: from Petos paradox to druggable cancer hallmark

Background
The somatic mutation theory predicts that cancer risk should scale proportionally with lifetime cell divisions; yet large-bodied and long-lived species exhibit lower-than-expected cancer incidence—a long-standing contradiction termed …

Single-cell RNA sequencing of baseline PBMCs predicts ICI efficacy and irAE severity in patients with NSCLC

Background
Immune checkpoint inhibitors (ICIs) have transformed treatment and have provided significant clinical benefits and durable responses for patients with advanced non-small cell lung cancer (NSCLC). However, only a small percentage of patients…
