However, testing a panel of reference genes is often time-consuming and expensive. In this work, we aimed to develop a set of multiplex real-time PCR assays for RT-qPCR analysis of commonly used housekeeping genes in laboratory rats. Using Hydrolysis probe (TaqMan®) technology, we have designed and optimized three triplex qPCR assays (Actb + Gapdh + B2m; Rpl13a + Sdha + Ppia; Hprt1+Pgk1+Ywhaz) demonstrating optimal PCR amplification efficiencies (from 94.7 to 100.5%) and repeatability. Novel assays allow expression analysis of 9 reference genes in 3 reactions making possible a more time-efficient choice of reference genes in RT-qPCR experiments in Wistar rats in comparison with widespread singleplex assays.Sporadic colorectal cancer (sCRC) is the third leading cause of cancer death in the Western world. Approximately, a quarter of sCRC patients present metastatic dissemination at the moment of diagnosis, the liver being the most frequently affected organ. Additionally, this group of CRC patients is characterized by a worse prognosis. In the last decades, significant technological developments for genome analysis have fostered the identification and characterization of genetic alterations involved in the pathogenesis of sCRC. However, genetic alterations involved in the metastatic process through which tumor cells are able to colonize other tissues with a different microenvironment, still remain to be fully identified. Here, we review current knowledge about the most relevant genomic alterations involved in the liver metastatic process of sCRC, including detailed information about the genetic profile of primary colorectal tumors vs. their paired liver metastases.Background Acromegaly is an uncommon syndrome caused by growth hormone-producing pituitary adenoma or pituitary gland hypertrophy.
