Abstract Therapy resistance and metastatic processes in prostate cancer (PCa) remain undefined, due to lack of experimental models that mimic different disease stages. We describe an androgen-dependent PCa patient-derived xenograft (PDX) model from treatment-naïve, soft tissue metastasis (PNPCa). RNA whole-exome sequencing the PDX organoids confirmed transcriptomic genomic similarity primary tumor. PNPCa harbors BRCA2 CHD1 somatic mutations, shows SPOP/FOXA1 -like signature microsatellite...
Bladder Cancer (BLCa) inter-patient heterogeneity is the primary cause of treatment failure, suggesting that patients could benefit from a more personalized approach. Patient-derived organoids (PDOs) have been successfully used as functional model for predicting drug response in different cancers. In our study, we establish PDO cultures BLCa stages and grades. PDOs preserve histological molecular parental tumors, including their multiclonal genetic landscapes, consistently share key...
Triggering receptor expressed on myeloid cells-1 (TREM-1) is a potent amplifier of pro-inflammatory innate immune reactions. While TREM-1-amplified responses likely aid an improved detection and elimination pathogens, excessive production cytokines oxygen radicals can also severely harm the host. Studies addressing pathogenic role TREM-1 during endotoxin-induced shock or microbial sepsis have so far mostly relied administration fusion proteins peptides representing part extracellular domain...
Abstract Although the introduction of novel targeted agents has improved patient outcomes in several human cancers, no such advance been achieved muscle-invasive bladder cancer (MIBC). However, recent sequencing efforts have begun to dissect complex genomic landscape MIBC, revealing distinct molecular subtypes and offering hope for implementation therapies. Her2 (ERBB2) is one most established therapeutic targets breast gastric but targeting not yet demonstrated anti-tumor activity MIBC....
Colorectal cancer (CRC) develops through a multistep process and is modulated by inflammation. However, the inflammatory pathways that support intestinal tumors at different stages remain incompletely understood. Interleukin (IL)-33 signaling plays role in inflammation, yet its contribution to pathogenesis of CRC unknown.Using immunohistochemistry on 713 resected human specimens, we show here IL-33 receptor ST2 are expressed low-grade early-stage CRCs, lesser extent higher-grade more...
Abstract Purpose Uncertain focal bone uptake (UBU) with intensive radiopharmaceutical avidity are frequently observed in patients undergoing [ 18 F]PSMA-1007 PET/CT for the detection of prostate cancer (PC). Such foci can pose diagnostic conundrums and risk incorrect staging. The aim this short communication is to share results PET-guided biopsies such foci. Methods A retrospective analysis revealed 10 who were referred our department biopsy UBU visible a previous PET/CT. F]-PSMA-1007 was...
Invasive fungal infections are associated with high mortality rates, and the lack of efficient treatment options emphasizes an urgency to identify underlying disease mechanisms. We report that disseminated Candida albicans infection is facilitated by interleukin-1 receptor antagonist (IL-1Ra) secreted from macrophages in two temporally spatially distinct waves. Splenic CD169+ release IL-1Ra into bloodstream, impeding early neutrophil recruitment. monocyte-derived tissue further impairs...
Several (pre-) clinical trials are currently investigating the benefit of HER2-targeted therapy in urothelial bladder cancer (UBC). Patients with HER2 amplified UBC could potentially profit from these therapies. However, little is known about histomorphology, protein expression patterns and occurrence alterations gene their tumors. Among 150 metastasizing primary UBC, 13 tumors were identified. Their histopathological features compared matched, non-amplified UBC. was determined by...
Metastases from primary prostate cancers to rare locations, such as the brain, are becoming more common due longer life expectancy resulting improved treatments. Epigenetic dysregulation is a feature of cancer, and distinct DNA methylation profiles have been shown be associated with mutually exclusive SPOP-mutant or TMPRSS2-ERG fusion genetic backgrounds. Using cohort cancer brain metastases (PCBM) 42 patients, matched tumors for 17 we carried out analysis examine epigenetic distinction...
Aims The Oxford Classification E score (endocapillary hypercellularity) predicts renal functional decline in IgA nephropathy (Ig AN ) patients free from steroid/immunosuppressive ( IS therapy, but is poorly reproducible. We hypothesise that endocapillary hypercellularity reflects glomerular inflammation and the presence of CD 68‐positive cells a more robust marker score. Methods results were quantified glomeruli tubulointerstitium biopsies 118 Ig patients, cell counts correlated with...
Improved survival rates for prostate cancer through more effective therapies have also led to an increase in the diagnosis of metastases infrequent locations such as brain. Here we investigate repertoire somatic genetic alterations present brain from 51 patients with (PCBM). We highlight clonal evolution occurring PCBM and demonstrate increased mutational burden, concomitant enrichment homologous recombination deficiency signature compared non-brain metastases. Focusing on known pathogenic...
Epstein-Barr virus (EBV)-associated gastric carcinomas (GC) represent a distinct and well-recognized subtype of cancer with prevalence around 10% all GC. In contrast, EBV has not been reported to play major role in esophageal adenocarcinomas (EAC) the gastro-esophageal junction (GEJ). We report our experiences on collections from two surgical centers discuss current state research this field. Tumor samples 465 primary resected (118 EAC, 73 GEJ 274 GC) were investigated. Presence was...
Aberrant interferon gamma (IFNγ) expression is associated with the pathogenesis of numerous autoimmune- and inflammatory disorders, including bowel diseases (IBD). However, requirement IFNγ for chronic intestinal inflammation remains controversial. The aim this study was thus to investigate role in experimental mouse models innate adaptive immune-cell mediated using genetically microbiota stabilized hosts. While we find that drives acute anti-CD40 colitis model an lymphoid cell...
Response classification after neoadjuvant chemotherapy in muscle-invasive bladder carcinoma is based on the TNM stage at radical cystectomy. We recently showed that histopathologic tumor regression grades (TRGs) add prognostic information to TNM. Our aim was validate significance of TRG cancer a multicenter setting. enrolled 389 patients who underwent cisplatin-based before cystectomy 8 centers between 2010 and 2016. Median follow-up 2.2 years. determined specimens by local pathologists....
Aberrant alternative pre-mRNA splicing (AS) events have been associated with several disorders. However, it is unclear whether deregulated AS directly contributes to disease. Here, we reveal a critical role of the regulator epithelial protein 1 (ESRP1) for intestinal homeostasis and pathogenesis. In mice, reduced ESRP1 function leads impaired barrier integrity, increased susceptibility colitis altered colorectal cancer (CRC) development. Mechanistically, these defects are produced in part by...
Current therapies to treat inflammatory bowel diseases have limited efficacy, significant side effects, and often wane over time. Little is known about the cellular molecular mechanisms operative in process of mucosal healing from colitis. To study such events, we developed a new model reversible colitis which adoptive transfer CD4+CD45RBhi T cells into Helicobacter typhlonius–colonized lymphopenic mice resulted rapid onset colonic inflammation that was through depletion colitogenic cells....
