A lack of reliably informative biomarkers to distinguish indolent and lethal prostate cancer is one reason this disease overtreated. miR-221 has been suggested as a biomarker in high-risk cancer, but there insufficient evidence its potential utility. Here we report that an independent predictor for cancer-related death, extending validating earlier findings. By mechanistic investigations showed regulates cell growth, invasiveness, apoptosis at least partially via STAT1/STAT3-mediated...

Abstract Prostate cancer (PCa) shows strong dependence on the androgen receptor (AR) pathway. Here, we show that squalene epoxidase (SQLE), an enzyme of cholesterol biosynthesis pathway, is overexpressed in advanced PCa and its expression correlates with poor survival. SQLE controlled by micro-RNA 205 (miR-205), which significantly downregulated PCa. Restoration miR-205 or competitive inhibition led to de novo biosynthesis. Furthermore, was essential for proliferation AR-positive cell lines,...

Oncogene activation and loss of tumor suppressor function changes the metabolic activity cancer cells to drive unrestricted proliferation. Moreover, adapt their metabolism sustain growth survival when access oxygen nutrients is restricted, such as in poorly vascularized areas. We show here that p53-deficient colon exposed tumor-like stress spheroid culture activated mevalonate pathway promote synthesis ubiquinone. This was essential maintain mitochondrial electron transport for respiration...

Downregulation of miR-221-3p expression in prostate cancer (PCa) predicted overall and cancer-specific survival high-risk PCa patients. Apart from PCa, levels a response to tyrosine kinase inhibitors (TKI) clear cell renal carcinoma (ccRCC) Since this role was explained with specific targeting VEGFR2, we examined whether regulated VEGFR2 PCa. First, confirmed VEGFR2/KDR as target gene cells by applying Luciferase reporter assays Western blotting experiments. Although mainly downregulated the...

Despite latest advances in prostate cancer (PCa) therapy, PCa remains the third-leading cause of cancer-related death European men. Dysregulation microRNAs (miRNAs), small non-coding RNA molecules with gene expression regulatory function, has been reported all types epithelial and haematological cancers. In particular, miR-221-5p alterations have PCa. miRNA data was retrieved from a comprehensive publicly available dataset 218 patients (GSE21036) levels were analysed. The functional role...

Background: Renal cell carcinoma (RCC) is divided into three major histopathologic groups—clear (ccRCC), papillary (pRCC) and chromophobe RCC (chRCC). We performed a comprehensive re-analysis of publicly available datasets from the TCGA (The Cancer Genome Atlas) database, thereby combining samples all subgroups, for an exploratory transcriptome profiling subgroups. Materials Methods: used FPKM (fragments per kilobase million) files derived ccRCC, pRCC chRCC cohorts representing...

Robust biomarkers to predict response immune checkpoint blockade (ICB) in metastatic urothelial carcinoma (mUC) are still demand. Recently, early C-reactive protein (CRP) kinetics and especially the novel CRP flare-response phenomenon has been associated with immunotherapy response.We conducted a multicentre observational study comprising 154 patients mUC treated ICB evaluate predictive value of previously described on-treatment kinetics: flare responders (at least doubling baseline within...

Introduction: Renal cancer is among the ten most common cancers in western societies, with renal cell carcinoma (RCC) accounting for 95% of malignant neoplasms. Recent advances surgical techniques and approaches have expanded treatment options, necessitating an evaluation optimal approaches. Methods: A retrospective, propensity-matched cohort 814 patients (1999-2021) was conducted comparing open minimally invasive (laparoscopic robotic-assisted) nephrectomy partial techniques, focusing on...

Clear cell renal carcinoma (ccRCC) characterized by a tumor thrombus (TT) extending into the inferior vena cava (IVC) generally indicates poor prognosis. Nevertheless, risk for recurrence after nephrectomy and thrombectomy varies. An applicable accurate prediction system to select ccRCC patients with TT of IVC (ccRCC/TT) at high is urgently needed, but has not been established up now. To our knowledge, possible role microRNAs (miRs) development ccRCC/TT or their impact as prognostic markers...

Metformin (MF) acts as a tumour-suppressor in renal cell carcinoma (RCC) by inhibiting the AKT/mTOR pathway via AMPK activation. Here, we explore influence of miR-21 and its target gene PTEN on MF effects CAKI-1 CAKI-2 cells.Proliferation assays (MTS) qRT-PCR after transient transfection with pre- anti-miR-21 treatment were conducted. AMPK-dependency was assessed siAMPK. The expression PTEN, AKT pre-miR-21 analysed.We demonstrate that cells, which found to be less sensitive towards MF,...

Die Therapie des Nierenzellkarzinoms (RCC) ist stark stadienabhängig und umfasst chirurgische Ansätze, Systemtherapien palliative Maßnahmen. Beim lokalisierten RCC steht die kurative operative Entfernung im Fokus, während in metastasierten Stadien eine Kombination aus Immun- Tyrosinkinase-Inhibitoren sowie individuelle Interventionen erfordern. adjuvante mit Checkpoint-Inhibitoren verbessert Prognose bei Hochrisikopatienten signifikant. orientieren sich an Prognosekriterien wie den...

Immune checkpoint blockade (IO) has revolutionised the treatment of metastatic renal cell carcinoma (mRCC). Early C-reactive protein (CRP) kinetics, especially recently introduced CRP flare-response phenomenon, shown promising results to predict IO efficacy in mRCC, but only been studied second line or later. Here, we aimed validate predictive value early kinetics for 1st-line mRCC with αPD-1 plus either αCTLA-4 (IO+IO) tyrosine kinase inhibitor (IO+TKI).In this multicentre retrospective...

(1) Background: Clear cell renal carcinoma extending into the inferior vena cava (ccRCCIVC) represents a clinical high-risk setting. However, there is substantial heterogeneity within this patient subgroup regarding survival outcomes. Previously, members of our group developed microRNA(miR)-based risk classifier-containing miR-21-5p, miR-126-3p and miR-221-3p expression-which significantly predicted cancer-specific (CSS) ccRCCIVC patients.
