Abstract CA19-9 values are regularly measured in patients with pancreatic cancer. Certainly, its potential as a biomarker has been compromised by false negative results and positive benign pancreatico-biliary diseases. For detection of PDAC recurrence, however, might play an important role. The aim this study is to analyze the accuracy for detecting recurrence All included were treated either at University Medical Center Goettingen, or Department Interdisciplinary Oncology Pneumonology,...

We used strategy of examining the tumors from subset PDAC cohorts worst survival understand underlying mechanisms aggressive progression identify molecular potential significance. Non-negative matrix factorization (NMF) clustering, using...
Pancreatic ductal adenocarcinoma (PDAC) exhibits distinct molecular subtypes: classical/progenitor and basal-like/squamous. Our study aimed to identify genes contributing the development of basal-like/squamous subtype, known for its aggressiveness. Transcriptome analyses revealed consistent upregulation SERPINB3 in PDAC, correlating with reduced patient survival. transgene expression PDAC cells enhanced vitro invasion promoted lung metastasis a mouse xenograft model. Metabolome unveiled...
Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy and refractory to available treatments. Delineating the regulatory mechanisms of metabolic reprogramming, key event in pancreatic cancer progression, may identify candidate targets with potential therapeutic significance. We hypothesized that inflammatory signaling pathways regulate adaptations cancer. Metabolic profiling tumors from PDAC patients high‐ (>median, n = 31) low‐NOS2 (inducible nitric oxide synthase; <median,...
Abstract Pancreatic ductal adenocarcinoma (PDAC) encompasses diverse molecular subtypes, including the classical/progenitor and basal-like/squamous each exhibiting distinct characteristics, with latter known for its aggressiveness. We employed an integrative approach combining transcriptome metabolome analyses to pinpoint potential genes contributing subtype differentiation. Applying this our NCI-UMD-German a validation cohort, we identified LIM Domain Only 3 (LMO3), transcription co-factor,...
Pancreatic ductal adenocarcinoma (PDAC) is a heterogeneous disease with distinct molecular subtypes described as classical/progenitor and basal-like/squamous PDAC. We hypothesized that integrative transcriptome metabolome approaches can identify candidate genes whose inactivation contributes to the development of aggressive subtype. Using our integrated approach, we identified endosome-lysosome associated apoptosis autophagy regulator 1 (ELAPOR1/KIAA1324) tumor suppressor in both...
Background: Postoperative liver failure (PLF) is a severe complication after major resection (MLR). To increase the safety of patients, clinical bedside tests are great importance. However, limitations their applicability and validity impair value. Methods: Preoperative measurements maximum capacity (LiMAx) were performed in n = 40 who underwent MLR (≥3 segments). Matched postoperative LiMAx was measured 21 patients. Liver function compared between pretreated patients (n 11 with portal vein...
Inflammation and aberrant cellular metabolism are widely recognized as hallmarks of cancer. In pancreatic ductal adenocarcinoma (PDAC), inflammatory signaling metabolic reprogramming tightly interwoven, playing pivotal roles in the pathogenesis progression disease. However, regulatory functions mediators cancer have not been fully explored. Earlier, we demonstrated that pro-inflammatory mediator macrophage migration inhibitory factor (MIF) enhances disease by inhibiting its downstream...
Abstract Pancreatic ductal adenocarcinoma (PDAC) manifests diverse molecular subtypes, including the classical/progenitor and basal-like/squamous with latter known for its aggressiveness. We employed integrative transcriptome metabolome analyses to identify potential genes contributing subtype differentiation metabolic features. Our comprehensive analysis revealed that adrenoceptor alpha 2A (ADRA2A) was downregulated in subtype, suggesting role as a candidate suppressor of this subtype....
Introduction Anti-EGFR targeted therapy is of increasing importance in advanced colorectal cancer and prior KRAS mutation testing mandatory for therapy. However, at which occasions this should be performed still under debate. We aimed to assess patients with locally rectal whether there intra-specimen heterogeneity upon preoperative chemoradiotherapy (CRT), if are any changes status due intervention. Materials Methods analyses were 199 tumor samples from 47 cancer. To evaluate the between...
Background: Patients with locally advanced rectal cancer are treated preoperative chemoradiotherapy followed by surgical resection. Despite similar clinical parameters (uT2-3, uN+) and standard therapy, patients’ prognoses differ widely. A possible prediction of prognosis through microRNAs as biomarkers out treatment-naïve biopsies would allow individualized therapy options. Methods: Microarray analysis 45 microdissected from patients was performed to identify potential predict overall...
