2. 26. Inter and intra-tumor models of somatic evolution in cancer

   Author : Mohammadreza Mohaghegh Neyshabouri; Jens Lagergren; Ben Raphael; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cancer progression models; MCMC; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

   Abstract : Cancer is a disease caused by the accumulation of somatic mutations in an evolutionary process. Mutations in so-called cancer driver genes provide the harboring cells with particular selective advantages and result in cancer progression. READ MORE

4. 27. Analysis of Immunoglobulin Genes and Telomeres in B cell Lymphomas and Leukemias

   Author : Sarah Walsh; Richard Rosenquist; Christer Sundström; Anna Laurell; Andreas Rosenwald; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; B cell lymphoma leukemia; mantle cell lymphoma; hairy cell leukemia; lymphoplasmacytic lymphoma; immunoglobulin genes; antigen selection; telomeres; cellular origin; somatic hypermutation; Genetik; Clinical genetics; Klinisk genetik;

   Abstract : B cell lymphomas and leukemias are heterogeneous tumors with different cellular origins. Analysis of immunoglobulin (Ig) genes enables insight into the B cell progenitor, as Ig somatic hypermutation correlates with antigen-related B cell transit through the germinal center (GC).

5. 28. Mosaic loss of chromosome Y : methods for detection and consequences for affected leukocytes and men

   Author : Marcus Danielsson; Lars A. Forsberg; Ståhl Patrik; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mosaic loss of chromosome Y; mLOY; somatic mosaicism; Medicinsk genetik; Medical Genetics;

   Abstract : It has been known for centuries that men live shorter lives than women, but until recently, the biological mechanisms driving this sex bias has been poorly understood. Mosaic loss of chromosome Y (mLOY) refers to chromosome Y aneuploidy, a male specific and the most common somatic mutation in human blood cells. READ MORE

6. 29. Immunoglobulin Gene Analysis in Different B cell Lymphomas : With Focus on Cellular Origin and Antigen Selection

   Author : Mia Thorsélius; Richard Rosenquist Brandell; Christer Sundström; Anders Rosén; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; B cell lymphoma; Immunoglobulin; V gene; somatic hypermutation; antigen selection; quantitative PCR; Genetik; Clinical genetics; Klinisk genetik;

   Abstract : B cell lymphoma (BCL) comprises a biologically and clinically heterogeneous group of tumors deriving from different stages of B cell development. The immunoglobulin (Ig) variable heavy chain (VH) gene rearrangement is unique for each BCL and can be used to reveal cellular origin, to study signs of antigen selection and to quantify tumor cell load.

7. 30. Stereotyped B Cell Receptors in Chronic Lymphocytic Leukaemia : Implications for Antigen Selection in Leukemogenesis

   Author : Fiona Murray; Richard Rosenquist Brandell; Kostas Stamatopoulos; Gunilla Enblad; Gerard Tobin; Manlio Ferrarini; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic lymphocytic leukaemia; immunoglobulin genes; somatic hypermutation; stereotyped B cell receptors; antigen selection; Molecular biology; Molekylärbiologi;

   Abstract : Biased immunoglobulin heavy variable (IGHV) gene usage and distinctive B-cell receptor (BCR) features have been reported in chronic lymphocytic leukaemia (CLL), which may reflect clonal selection by antigens during disease development. Furthermore, the IGHV gene mutation status distinguishes two clinical entities of CLL, where patients with unmutated IGHV genes have an inferior prognosis compared to those with mutated IGHV genes.
