Evaluation of Betulinic Acid Derivatives as PET Tracers for Hypoxia-Induced Carbonic Anhydrase IX (CA IX) Expression
Non-invasive visualisation of the expression of hypoxia-related proteins, such as carbonic anhydrase IX (CA IX), by positron emission tomography (PET) could provide important information on the oxygenation sta...

Acidosis-Induced Regulation of Egr1 and Ccn1 In Vitro and in Experimental Tumours In Vivo
Extracellular acidosis is a characteristic of solid tumours, resulting from hypoxia-induced glycolytic metabolism as well as from the “Warburg effect” (aerobic glycolysis). The acidic environment has shown to ...

Role of the mTOR Signalling Pathway During Extracellular Acidosis in Tumour Cells
The metabolic microenvironment of solid tumours is often dominated by extracellular acidosis which results from glycolytic metabolism. Acidosis can modulate gene expression and foster the malignant progression...

Impact of Acidosis-Regulated MicroRNAs on the Expression of Their Target Genes in Experimental Tumors In Vivo
In comparison to normal tissue, solid tumors show an acidic extracellular pH, which results from hypoxia-induced glycolytic metabolism and the Warburg effect. Since acidosis modulates the expression of differe...

Extracellular Acidosis Regulates the Expression of Inflammatory Mediators in Rat Epithelial Cells
Acidification of the cellular microenvironment is found in different pathological states such as inflammation, ischemia and in solid tumors. It can affect cell function and phenotype, and by this aggravate the...

Hypoxia-Related Tumor Acidosis Affects MicroRNA Expression Pattern in Prostate and Breast Tumor Cells
MicroRNAs (miRNAs) are small non-coding RNA sequences which are able to modulate the expression of many functional proteins. The expression level of miRNAs can be modulated by parameters of the tumor microenvi...

Nanoscopic phase-analysis of SiC containing BaTiO3-ceramic
The formation of fresnoite (Ba2TiSi2O8) from BaTi1.01O3.02 by addition of SiC was investigated in the temperature range from 700 to 1350 °C. Solid state reactions at the interface of grains indicate a formation ...
