    Abstract : Background Colorectal cancer (CRC) is the second most common malignancy in developed countries. The mortality is high, with nearly half of patients dying from the disease. The primary treatment of CRC is surgery, and decisions about additional treatment with chemotherapy are based mainly on tumor stage. READ MORE

  4. 2. Biological signature of HER2-positive breast cancer

    Abstract : Hepatitis C virus (HCV) is an RNA virus that causes chronic infection, which can lead to hepatocellular carcinomas in humans. Besides liver diseases, the chronic HCV infection causes a broad spectrum of extrahepatic complications such as lymphoproliferative, metabolic and autoimmune disorders. READ MORE

  7. 5. Epigenetic Dysregulations in the Brain of Human Alcoholics : Analysis of Opioid Genes

    Author : Igor Bazov; Georgy Bakalkin; Catharina Lavebratt; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neuropeptides; dynorphin; human brain; alcohol dependence; epigenetics; gene transcription;

    Abstract : Neuropeptides are special in their expression profiles restricted to neuronal subpopulations and low tissue mRNA levels. Genetic, epigenetic and transcriptional mechanisms that define spatiotemporal expression of the neuropeptide genes have utmost importance for the formation and functions of neural circuits in normal and pathological human brain.
