Differential gene expression of fatty acid binding proteins during porcine adipogenesis


Authors: Samulin, Johanna; Berget, Ingunn; Lien, Sigbjorn; Sundvold, Hilde

Four different subtypes of fatty acid binding proteins i.e. liver-type FABP1, heart/muscle-type FABP3, adipocyte-type FABP4 and epithelial/epidermal-type FABP5 are expressed in adipose tissue. However, only the regulatory role of FABP4 in adipogenesis has been thoroughly investigated. To increase the knowledge on possible roles of these FABP subtypes in preadipocyte differentiation, gene expression patterns were examined during adipogenesis in pig (Sus scrofa). FABP1 expression was induced in proliferating cells, whereas FABP3, FABP4 and FABP5 expression increased throughout preadipocyte differentiation. Interestingly, the FABP4 and FABP5 expression increased early in the differentiation, followed by FABP3 later in the differentiation process. This indicates a role of FABP4 and FABP5 in intracellular fatty acid transport during initiation of differentiation, whereas, FABP3 likely is involved in the transport of fatty acids during intermediate stages of adipogenesis. In this study we demonstrate that FABP3, FABP4 and FABP5 expression is correlated with that of the peroxisome proliferator-activated receptors alpha and gamma (PPARA and PPARG). Altogether, this suggests a role of FABP1 during cell proliferation, whereas a coordinated expression of FABP3, FABP4 and FABP5 together with that of PPARA, PPARG1 and PPARG2 might be critical for the metabolic regulation during porcine adipogenesis.

Molecular Portrait of Metastasis-Competent Circulating Tumor Cells in Colon Cancer Reveals the Crucial Role of Genes Regulating Energy Metabolism and DNA Repair


Authors: Alix-Panabieres, Catherine; Cayrefourcq, Laure; Mazard, Thibault; Maudelonde, Thierry; Assenat, Eric; Assou, Said

BACKGROUND: Unraveling the molecular mechanisms that regulate the biology of metastasis-competent circulating tumor cells (CTCs) is urgently needed to understand metastasis formation and tumor relapse. Our group previously established the first cell line (CTC-MCC-41) derived from metastasis-competent CTCs of a patient with colon cancer. METHODS: In this study, we analyzed the transcriptome of CTC-MCC-41 cells using Human Genome U133 Plus 2.0 microarrays with the aim of unraveling the molecular basis of their special features (stem cell properties and ability to initiate and support metastasis formation). RESULTS: Comparison of the transcriptome data of metastasis-competent CTC-MCC-41 cells and of HT-29 cells (derived from a primary colon cancer) highlights the differential expression of genes that regulate energy metabolism [peroxisome proliferator-activated receptor gamma coactivator 1A (PPARGC1A), peroxisome proliferator-activated receptor gamma coactivator 1B (PPARGC1B), fatty acid binding protein 1 (FABP1), aldehyde dehydrogenase 3 family member A1 (ALDH3A1)], DNA repair [BRCA1 interacting protein C-terminal helicase 1 (BRIP1), Fanconi anemia complementation group B (FANCB), Fanconi anemia complementation group M (FANCM)], and stemness [glutaminase 2 (GLS2), cystathionine-beta-synthase (CBS), and cystathionine gamma-lyase (CM)]. The differential expression of 20 genes was validated by quantitative reverse transcription PCR. CONCLUSIONS: This study gives a comprehensive outlook on the molecular events involved in colon cancer progression and provides potential CTC biomarkers that may help develop new therapies to specifically target CTCs with stem cell properties that cause metastases and tumor relapse in patients with colon cancer.
