Mesenchymal-like tumor cells and myofibroblastic cancer-associated fibroblasts are associated with progression and immunotherapy response of clear-cell renal cell carcinoma [scRNA-seq]

Project description:Immune checkpoint inhibitors (ICI) represent the cornerstone for treatment of patients with metastatic clear-cell renal cell carcinoma (ccRCC). Despite a favorable response for a subset of patients, others experience primary progressive disease highlighting the need to precisely understand plasticity of cancer cells and their crosstalk with the microenvironment to better predict therapeutic response and personalize treatment. Single-cell RNA sequencing of ccRCC at different disease stages and normal adjacent tissue (NAT) from patients identified 46 cell populations, including 5 tumor subpopulations, characterized by distinct transcriptional signatures representing an epithelial to mesenchymal transition gradient and a novel inflamed state. Deconvolution of the tumor and microenvironment signatures in public datasets and in data from the BIONIKK clinical trial (NCT02960906) revealed a strong correlation between mesenchymal-like ccRCC cells and myofibroblastic cancer-associated fibroblasts (myCAFs), which are both enriched in metastases and correlate with poor patient survival. Spatial transcriptomics and multiplex immune staining uncovered spatial proximity of mesenchymal-like ccRCC cells and myCAFs at the tumor-NAT interface. Moreover, enrichment in myCAFs was associated with primary resistance to ICI therapy in the BIONIKK clinical trial. This data highlights the epithelial-mesenchymal plasticity of ccRCC cancer cells and their relationship with myCAFs, a critical component of the microenvironment associated with poor outcome and ICI resistance.

EMILIN2 is associated with prognosis and immunotherapy in clear cell renal cell carcinoma.

Project description:Background: EMILIN2 is a platelet-associated elastin that regulates angiogenesis. It has recently been found to play an essential role in various tumors. Nevertheless, the mechanism of action of EMILIN2 in clear cell renal cell carcinoma (ccRCC) remains unclear. Methods: Samples from 33 cancers were obtained from UCSC Xena and The Cancer Genome Atlas (TCGA) database. The relationship between EMILIN2 expression and the clinicopathological characteristics and immune infiltration of ccRCC was investigated. Nonnegative matrix factorization (NMF) was used to classify ccRCC patients. A multigene risk prediction model of ccRCC was constructed using LASSO regression and multivariate regression analysis. A nomogram survival probability prediction map and calibration curve were constructed based on clinical information. Results: EMILIN2 is significantly overexpressed in ccRCC, a phenomenon that is associated with poor prognosis. Meanwhile, EMILIN2 expression is closely related to tumor immune infiltration in ccRCC. Patients with clear cell renal cell carcinoma were divided into two subtypes using NMF, with subtype 2 showed poor prognosis. Next, we established a risk score model for ccRCC based on the common differentially expressed genes (DEGs) between subtypes and groups based on EMILIN2 expression. The results indicated poor prognosis in the high-risk group in the training set and were confirmed in the validation set. Conclusion: Our findings suggest that EMILIN2 expression is closely associated with immune infiltration in ccRCC. EMILIN2 expression is negatively correlated with the prognosis of ccRCC patients. Here, we developed a tool that could predict the prognosis of ccRCC patients.

MCL-1 as a molecular switch between myofibroblastic and pro-angiogenic features of breast cancer-associated fibroblasts

Project description:Breast cancer-associated-fibroblasts (bCAFs) consist of two pro-tumoral populations: inflammatory CAFs (iCAF) releasing pro-inflammatory cytokines, and myofibroblastic CAFs (myCAF) known for their extensive production of extracellular matrix proteins and immunosuppressive features. We have previously shown that targeting the anti-apoptotic protein MCL-1 in primary culture of bCAFs directly derived from human samples reduces their myofibroblastic characteristics linked to actomyosin cytoskeleton disorganization and mitochondrial fragmentation. In this study, we explore the involvement of this protein in phenotypic differentiation and plasticity of bCAFs. Single-cell RNA-sequencing analysis reveals a shift from wound-myCAF to IL-iCAFs phenotype expressing genes involved in inflammation like IL-8, IL-1β, CXCL1, CXCL3, CCL2 and in angiogenesis like VEGF after MCL-1 gene silencing in bCAFs. In vitro, targeting of MCL-1 in bCAFs induces an increase of VEGF secretion associated with enhanced endothelial cell tubulogenesis. In ovo, using chicken chorioallantoic membrane model, we engrafted breast cancer cells and bCAFs to study vascularization. Our data suggest that a low level of MCL-1 expression in bCAF is associated with greater peritumoral vascular density in a VEGF-dependent manner. Furthermore, chemotherapy that downregulated MCL-1 expression in bCAFs is accompanied by the same pro-angiogenic effects. Mechanistically, pharmacological inhibition of MCL-1 promotes mitochondrial outer membrane permeabilization and NF-κB activation in cGAS-STING independent-manner. Blockage of NF-κB activity with an IKKβ inhibitor counteracts VEGF and pro-inflammatory factors transcription induced by MCL-1 inhibition in bCAFs. Our findings highlight a novel role for MCL-1 in regulating the pro-angiogenic properties of bCAFs, and provide new elements for characterizing the different bCAFs subpopulations.

Emerging Immunotherapy Approaches for Advanced Clear Cell Renal Cell Carcinoma.

Project description:The most common subtype of renal cell carcinoma is clear cell renal cell carcinoma (ccRCC). While localized ccRCC can be cured with surgery, metastatic disease has a poor prognosis. Recently, immunotherapy has emerged as a promising approach for advanced ccRCC. This review provides a comprehensive overview of the evolving immunotherapeutic landscape for metastatic ccRCC. Immune checkpoint inhibitors (ICIs) like PD-1/PD-L1 and CTLA-4 inhibitors have demonstrated clinical efficacy as monotherapies and in combination regimens. Combination immunotherapies pairing ICIs with antiangiogenic agents, other immunomodulators, or novel therapeutic platforms such as bispecific antibodies and chimeric antigen receptor (CAR) T-cell therapy are areas of active research. Beyond the checkpoint blockade, additional modalities including therapeutic vaccines, cytokines, and oncolytic viruses are also being explored for ccRCC. This review discusses the mechanisms, major clinical trials, challenges, and future directions for these emerging immunotherapies. While current strategies have shown promise in improving patient outcomes, continued research is critical for expanding and optimizing immunotherapy approaches for advanced ccRCC. Realizing the full potential of immunotherapy will require elucidating mechanisms of response and resistance, developing predictive biomarkers, and rationally designing combination therapeutic regimens tailored to individual patients. Advances in immunotherapy carry immense promise for transforming the management of metastatic ccRCC.
