   Sammanfattning : Heparan sulfate proteoglycans (HSPGs) consist of a protein core to which several linear, negatively charged heparan sulfate (HS) chains are covalently attached. HSPGs are expressed on the cell surface and in the extra-cellular matrix (ECM) where they have diverse biological functions, for example co-receptor functions. LÄS MER

3. 2. TGFβ and LXR signaling in hepatocellular carcinoma

   Författare :Claudia Bellomo; Aristidis Moustakas; Lars Holmgren; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hepatocellular Carcinoma; high-throughput imaging; small molecules; epithelial plasticity; LXR; Snail; TGFβ; tumor suppression; reactive oxygen species; cancer-associated fibroblast; myofibroblast; Smad3; αSMA;

   Sammanfattning : Hepatocellular carcinoma (HCC) is one of the most prevalent cancer types in the Western world and in the Asia-pacific regions, with its incidence expected to rise up to 22 million cases till 2020. Hepatocellular carcinoma etiology is mainly due to hepatitis B (HBV) and hepatitis C (HCV) infections, and to a lesser extent it is determined by the development of alcohol-driven cirrhosis and non-alcoholic steatohepatitis (NASH).

4. 3. Epigenetic Regulation of Replication Timing and Signal Transduction

   Författare :Rosita Bergström; Aristidis Moustakas; Carl-Henrik Heldin; Rolf Ohlsson; Alain Mauviel; Uppsala universitet; []
   Nyckelord :Cell and molecular biology; Chromatin; CTCF; Epigenetics; Genomic Imprinting; H19; Id; Igf2; Insulator; Replication; Signal Transduction; Smad; TGF-β; Transcription; Cell- och molekylärbiologi;

   Sammanfattning : Upon fertilization the paternal and maternal genomes unite, giving rise to the embryo, with its unique genetic code. All cells in the human body are derived from the fertilized ovum: hence they all contain (with a few exceptions) the same genetic composition. LÄS MER

5. 4. Mechanisms for Quantitative Regulation of TGF-ß Signaling

   Författare :Markus Dahl; Aristidis Moustakas; Carl-Henrik Heldin; Daniel Constam; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biologi med inriktning mot molekylär cellbiologi; Biology with specialization in Molecular Cell Biology;

   Sammanfattning : Cancer is a widely spread disease, and many cancer variants are today still difficult to treat. Efforts are being made to understand the complexity of cancer, both at a clinical level but also at a pre-clinical level. LÄS MER

7. 5. Micro-environmental control of tumor differentiation and invasiveness

   Författare :Caroline Gélabert; Aristidis Moustakas; Alexander Pietras; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; cell signaling; TGFβ; non-coding RNAs; metabolism;

   Sammanfattning : The transforming growth factor β (TGFβ) family participates in embryonic development and adult tissue homeostasis. In early stages of tumorigenesis, TGFβ promotes cell cycle arrest and apoptosis; however, in advanced malignancies, TGFβ promotes tumor cell migration and metastasis via the induction of epithelial-tomesenchymal transition (EMT).
