2. 1. Application of Genomic and Expression Arrays for Identification of new Cancer Genes

   Author : Helena Nord; Teresita Díaz de Ståhl; Jan Dumanski; Susan Pfeifer; Blomquist Erik; Segersten Ulrika; David Gisselsson Nord; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Array-CGH; Expression array; Copy number variation; Glioblastoma; Medulloblastoma; Bladder carcinoma; Oncogenes; Tumor suppressor genes; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; Medical genetics; Medicinsk genetik; Tumour biology; Tumörbiologi; Genetics; Genetik; Medical Genetics; Medicinsk genetik;

   Abstract : Copy number variation (CNV) comprises a recently discovered kind of variation involving deletion and duplication of DNA segments of variable size, ranging from a few hundred basepairs to several million. By altering gene dosage levels or disrupting proximal or distant regulatory elements CNVs create human diversity. READ MORE

4. 2. Redefining the essential molecular aspects that drive interactions between small molecules and G-quadruplex DNA

   Author : Måns Andréasson; Erik Chorell; Anna Linusson Jonsson; Jan Kihlberg; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; G-Quadruplexes; DNA; Oncogenes; G4 ligands; heterocycles; macrocycles; organic synthesis; molecular interactions; rational compound design; medicinal chemistry.; medicinal chemistry; läkemedelskemi; organisk kemi; Organic Chemistry;

   Abstract : G-Quadruplex (G4) structures are secondary nucleic acid structures located in guanine-rich regions of DNA and RNA sequences, involved in gene regulation and cellular maintenance. Efforts to target G4s in a therapeutic setting are scarce, mainly due to vague details about the binding interactions between the ligands and the G4 structure combined with the lack of emphasis on drug-like properties early in the ligand development process.

5. 3. Array-based Genomic and Epigenomic Studies in Healthy Individuals and Endocrine Tumours

   Author : Johanna Sandgren; Gunnar Westin; Teresita Diaz de Ståhl; Göran Åkerström; Ola Hessman; Winand Dinjens; Uppsala universitet; []
   Keywords : genome; copy number variants; cancer; Pheochromocytoma; epigenome; array-CGH; ChIP-chip; gene expression; tumour suppressor genes; oncogenes; MEDICINE; MEDICIN; Kirurgi; Surgery;

   Abstract : The human genome is a dynamic structure, recently recognized to present with significant large-scale structural variation. DNA-copy number changes represent one common type of such variation and is found both between individuals and within the somatic cells of the same individual, especially in disease states like cancer.

6. 4. Identification and Characterization of Novel Candidate Oncogenes

   Author : Marina Mencinger; Avdelningen för klinisk genetik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk genetik; Clinical genetics; RBP56; APRIL; TFG; FUS; EWS; EST database; fusion genes; chromosome; molecular genetics; cancer; Cytology; oncology; cancerology; Cytologi; onkologi;

   Abstract : Using computer-assisted sequence homology searches we identified three genes encoding proteins similar to certain fusion partner proteins in cancer. The novel APRIL gene was localized to 15q25 and encodes a protein, containing an acidic amino-acid region similar to that/those of leukemia-associated fusion partner proteins DEK and SET. READ MORE

7. 5. Inhibition of crucial oncogenes by pharmacologically activated p53

   Author : Yao Shi; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The tumor suppressor p53 is a transcriptional factor which is frequently inactivated in cancer, either by point mutations or by its negative regulators, such as Mdm2 and MdmX. Reactivation of p53 by small molecules is a promising strategy to treat cancer. READ MORE
