The stability of standard gene expression is an elementary prerequisite for internal standardisation of target gene expression data and many so called housekeeping genes with assumed stable expression can exhibit either up- or down-regulation under some experimental conditions. The developed, and herein presented, software called BestKeeper determines the(More)
The process of luteolysis requires very subtly modulated coordination of different factors and regulation systems. Immune cells and cytokines were shown to be relevant for bovine luteolysis. The aim of this study was to investigate the detailed pattern of mRNA expression of the pro-inflammatory cytokines tumor necrosis factor alpha (TNFalpha), TNF receptor(More)
Housekeeping genes are commonly used as endogenous references in quantitative RT-PCR. Ideally these genes are constitutionally expressed by all cell types and do not vary under experimental conditions. Tissues of 9 normal testes and 22 classical pure seminoma were obtained for RNA-extraction. Real-time RT-PCR was used to examine the mRNA-expression of(More)
The components of the IGF-system were shown to be differentially regulated in bovine antral follicles and corpora lutea (CL) during different stages of the estrous cycle, and to have important functions for specific stages. The aim of this study was to investigate the detailed pattern of mRNA expression of most constituents of the IGF-system and their(More)
Comparison of reverse transcriptases in absolute and relative gene expression analysis Inhibition of real-time RT-PCR quantification due to tissue specific contaminants Determination of stable housekeeping genes, differentially regulated target genes and sample integrity: BestKeeper – Excel-based tool using pair-wise correlations Quantifizierungsstrategien(More)
Insulin-like growth factors (IGF) have mitogenic and antiapoptotic functions, and may be involved in tumor growth. The purpose of the study was to investigate the role of IGF components in seminoma compared to normal testis. Normal testicular tissues from autopsy cases and seminoma from surgery cases were obtained for microarray and real-time reverse(More)
