The Effect of Immunotherapy PD-1 Blockade on Acute Bone Cancer Pain: Insights from Transcriptomic and Microbiomic Profiling

Project description:Background: The skeletal system ranks as the third most common site for cancer metastasis, often leading to pain with nociceptive and neuropathic features. PD-1-targeting therapeutic antibodies offer effective cancer treatment but can cause treatment-related acute pain. Understanding the mechanisms of this pain and identifying potential interventions is still a challenge. Methods: A murine model of bone cancer pain was established using Lewis lung carcinoma (LLC) cells, followed by intravenous administration of nivolumab, a human anti-PD-1 monoclonal antibody. Pain thresholds were measured, and micro-CT images of the skeletal system were obtained. High-throughput sequencing of the spinal cord/colon transcriptome during the acute phase of bone cancer pain and gut microbiota analysis were performed. Immunofluorescence staining and western blot experiments assessed spinal cord microglia activation and acute pain-associated molecules. Results: PD-1 inhibition with nivolumab protected against bone degradation initiated by LLC cell administration but consistently induced acute pain during nivolumab treatment. Spinal cord and colon transcriptomics revealed an immunopathological pattern during tumor progression and the acute pain phase, with notable changes in interleukin and S100 gene families. Gut microbiota analysis post-immunotherapy showed a decline in beneficial bacteria associated with SCFA production. Activation of spinal cord microglia and enhanced glycolytic metabolism were confirmed as key factors in inducing acute pain following immunotherapy. Conclusions: This study reveals that nivolumab induces acute pain by activating microglia and enhancing glycolytic metabolism in the treatment of bone cancer and uncovers connections between transcriptomic changes, gut microbiota, and acute pain following ICB treatment. It offers novel insights into the relationship between immune checkpoint blockade therapies and pain management.

Multi-omics analyses of changes in the tumor microenvironment of pancreatic adenocarcinoma following neoadjuvant treatment with anti-PD-1 antibody

Project description:Successful pancreatic ductal adenocarcinoma (PDAC) immunotherapy necessitates optimization and maintenance of activated effector T cells (Teffs). We prospectively collected and applied multi-omics analysis to paired, pre- and post-treatment PDAC specimens collected in a platform neoadjuvant study of GVAX vaccine +/- nivolumab (anti-PD-1) to uncover sensitivity and resistance mechanisms. We show that GVAX-induced tertiary lymphoid aggregates become immune-regulatory sites in response to GVAX+nivolumab. Higher densities of tumor-associated neutrophils (TANs) following GVAX+nivolumab portend poorer overall survival (OS). Increased T cells expressing CD137 associated with cytotoxic Teff signatures and correlated with increased OS. Bulk and single-cell RNA-sequencing found that nivolumab alters CD4+ T cell chemotaxis signaling in association with CD11b+ neutrophil degranulation, and CD8+ T cell expression of CD137 required for optimal T cell activation. These findings provide new insights into PD-1-regulated immune pathways in PDAC that should inform more effective therapeutic combinations that include TAN regulators and T cell activators.

Tumor Growth and Prognosis of Squamous Cell Carcinoma of the Head and Neck is Linked to Protein Kinase C Alpha

Project description:Protein Kinase C alpha (PKC) is a critical mediator of cell signaling and cancer growth. We show that PKC inhibitors decrease proliferation in squamous cell carcinoma of the head and neck (SCCHN) cells and abrogate growth of SCCHN tumors in mouse xenografts. Analysis of gene expression arrays reveals that PKC regulates cell cycle genes required for DNA synthesis. In particular, PKC increases cyclin E protein expression, cyclinE/cdk2 complex formation, and transcription of cyclin E and E2F target genes. Consistent with this mechanism, expression of cyclin E rescues the block in DNA synthesis caused by PKC inhibition. In SCCHN tissue, PKC and cyclin E expression increase progressively from normal and dysplastic to malignant human head and neck tissue. Furthermore, PKC expression correlates with poor prognosis in SCCHN. These results demonstrate that PKC regulates growth by stimulating DNA synthesis through cyclin E and E2F and identify PKC as a therapeutic target that is highly expressed in aggressive SCCHN.

RNA sequensing data of a phase 2 clinical trial of pancreatic ductal adenocarcinoma treated with entinostat in combination with nivolumab

Project description:We conducted a single-center, open-label, Simon two-stage, phase II study of entinostat in combination with the PD1 inhibitor nivolumab in patients with advanced pancreatic ductal adenocarcinoma. Patients received oral entinostat 5 mg once a week. After a 14-day lead-in with entinostat monotherapy, patients concurrently receive entinostat 5 mg orally once a week plus nivolumab 240 mg intravenously until the time of progression or unacceptable toxicities.

Stromal and epithelial changes in breast cancer following endocrine treatment

Project description:Patients diagnosed with breast cancer were recruited to an important trial, the Tamoxifen Window Trial, in two series, series A during 1988-1989 and series B during 1989-1990. Some patients received tamoxifen for short windows. Clinical samples (biopsies) for this trial were collected before and after treatment. These biopsies were available as formalin-fixed paraffin-embedded (FFPE) tissue blocks. Responding patients and non-responding patients were determined by the change in the Ki67 scores. Responding patients were identified as those that had demonstrated a reduction in their Ki67 scores, and non-responding patients were identified as those in which Ki67 had not changed or had increased. The change in the percentage of Ki67 positive tumour cells was obtained by comparing the pre-treatment and post-treatment scores and calculating the difference in the scores. Laser capture microdissection (LCM) was utilised to microdissect the epithelial and stromal cells from the post-treatment breast cancer FFPE tissue sections of responding and non-responding patients. Samples obtained following LCM underwent RNA extraction and were subsequently used for gene expression profiling.

A pilot study of the Bruton's tyrosine kinase inhibitor ibrutinib in combination with nivolumab in patients with metastatic solid tumors

Project description:Background: Preclinical work has demonstrated that ibrutinib inhibits the generation, migration and immunosuppressive function of myeloid-derived suppressor cells (MDSC). A pilot study tested the combination of ibrutinib and nivolumab in patients with metastatic solid tumors. Methods: Sixteen patients with metastatic solid malignancies were treated with ibrutinib (420 mg) daily and nivolumab (240 mg) IV on days 1 and 15 of 28 day cycles. Ibrutinib dosing started 7 days before cycle 1 of nivolumab and was given until cycle 1, day 8 of nivolumab. The effect of ibrutinib alone and in combination with nivolumab on circulating MDSC and immune subsets and cytokine/chemokine levels were measured. Single-cell RNA and TCR sequencing was also performed. Results: The most common treatment-related AEs were fatigue (31%) and anorexia (31%). Five patients had a clinical response (4 partial, 1 complete). Four patients had stable disease at 3 months. Median progression-free survival was 3.5 months and median overall survival 10.8 months. MDSC levels increased following 7 days of single-agent ibrutinib compared to baseline (21.91% vs. 27.67%). There was increased T cell proliferation in response (33.9% vs. 40.06%, p<0.01) to the combination regimen. Plasma levels of CCL2, CCL3, CCL4, CCL13, IL- 8, and VEGF-α decreased with ibrutinib treatment. Ibrutinib treatment altered the transcriptional state of the myeloid cell compartment and led to increased cancer-associated TCR clonotypes. Conclusion: The combination of ibrutinib and nivolumab was well tolerated and ibrutinib significantly impacted MDSC and T cell function in patients with solid metastatic tumors.
