PURPOSE The standard treatment of patients with locally advanced rectal cancers comprises preoperative 5-fluorouracil-based chemoradiotherapy followed by standardized surgery. However, tumor response to multimodal treatment has varied greatly, ranging from complete resistance to complete pathologic regression. The prediction of the response is, therefore,(More)
HSP90 inhibition represents a promising route to cancer therapy, taking advantage of cancer cell-inherent proteotoxic stress. The HSP90-inhibitor ganetespib showed benefit in advanced clinical trials. This raises the need to identify the molecular determinants of treatment response. We tested the efficacy of ganetespib on a series of colorectal cancer(More)
OBJECTIVE Besides persisting high pulmonary arterial pressure and increased pulmonary vascular resistance, remodelling of pulmonary tissues and subsequently the right heart are the key pathomechanisms of pulmonary hypertension (PH). Extracellular matrix maintenance in this context plays a central role. METHODS We tested the hypothesis that plasma(More)
The estrogen receptor-α (ERα) determines the phenotype of breast cancers where it serves as a positive prognostic indicator. ERα is a well-established target for breast cancer therapy, but strategies to target its function remain of interest to address therapeutic resistance and further improve treatment. Recent findings indicate that proteasome inhibition(More)
BACKGROUND AND PURPOSE Preoperative chemoradiotherapy (CRT) represents the standard treatment for locally advanced rectal cancer. Tumor response and progression vary considerably. MicroRNAs represent master regulators of gene expression, and may therefore contribute to this diversity. MATERIAL AND METHODS Genome-wide microRNA (miRNA) profiling was(More)
Increased activity of signal transducer and activator of transcription 3 (STAT3) is common in human malignancies, including colorectal cancers (CRCs). We have recently reported that STAT3 gene expression correlates with resistance of CRC cell lines to 5-fluorouracil (5-FU)-based chemoradiotherapy (CT/RT). This is of considerable clinical importance, because(More)
BACKGROUND Growth differentiation factor-15 (GDF-15), a stress-responsive transforming growth factor-ß-related cytokine, is elevated and independently related to an adverse prognosis in systolic heart failure. OBJECTIVE This study aimed to investigate plasma levels of GDF-15 in patients with preclinical diastolic dysfunction or heart failure with normal(More)
OBJECTIVE Left ventricular diastolic dysfunction (LVDD) is considered a precursor of diabetic cardiomyopathy, while the metabolic syndrome (MetS) is associated with an increased risk of cardiovascular morbidity and mortality. This study aimed to evaluate the association between LVDD, MetS and glucose metabolism disturbances classified by oral glucose(More)
In human heart failure (HF), reduced cardiac function has, at least partly, been ascribed to altered calcium homeostasis in cardiomyocytes. The effects of the calcium sensitizer levosimendan on diastolic dysfunction caused by reduced removal of calcium from cytosol in early diastole are not well known. In this study, we investigated the effect of long-term(More)
OBJECTIVE C-reactive protein (CRP) is the prototype acute phase protein and a cardiovascular risk factor. Interleukin-1beta (IL-1beta) and IL-6 stimulate CRP synthesis in hepatocytes. We searched for additional pathways regulating CRP expression. METHODS AND RESULTS Primary human hepatocytes (PHHs) were treated with IL-1beta, IL-6, and protein kinase C(More)
