1. 21. Myeloid-Derived Suppressor Cells and Other Immune Escape Mechanisms in Chronic Leukemia

   Författare :Lisa Christiansson; Angelica S I Loskog; Ulla Olsson-Strömberg; Andreas Lundqvist; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic myeloid leukemia; myeloid-derived suppressor cells; sCD25; tyrosine kinase inhibitors; multiplex protein quantification; Medical Science; Medicinsk vetenskap;

   Sammanfattning : Chronic myeloid leukemia (CML) is characterized by the Philadelphia chromosome, a minute chromosome that leads to the creation of the fusion gene BCR/ABL and the transcription of the fusion protein BCR/ABL in transformed cells. The constitutively active tyrosine kinase BCR/ABL confers enhanced proliferation and survival on leukemic cells. LÄS MER

3. 22. Identification and characterisation of SMIM1 variants determining the Vel blood group

   Författare :Mikael Kronborg Christophersen; Avdelningen för hematologi och transfusionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood groups; Vel blood group system; genetic variation; transcriptional regulation;

   Sammanfattning : The Vel blood group antigen is present on red blood cells from all humans except rare Vel-negative individuals, who can form antibodies to Vel in response to transfusion or pregnancy. It was first described in 1952 as a high incidence antigen, while the molecular background was recently discovered to be a 17-bp deletion in Small Integral Membrane Protein 1, that causes a frame-shift mutation and abolishes SMIM1 expression, thus creating a Vel-negative phenotype.

4. 23. Genetic Cartography at Massively Parallel Scale

   Författare :Johan Dahlberg; Ann-Christine Syvänen; Adam Ameur; Michael C. Zody; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Acute Lymphoblastic Leukemia ALL ; RNA-Sequencing; Bioinformatics; Pooling; Whole Genome Sequencing; Medicinsk genetik; Medical Genetics; Bioinformatics; Bioinformatik;

   Sammanfattning : Massively parallel sequencing (MPS) is revolutionizing genomics. In this work we use, refine, and develop new tools for the discipline.MPS has led to the discovery of multiple novel subtypes in Acute Lymphoblastic Leukemia (ALL). In Study I we screen for fusion genes in 134 pediatric ALL patients, including patients without an assigned subtype. LÄS MER

5. 24. Computational Single-Cell Genomics Methods for Cell State Estimation and their Application to Hematopoietic Systems

   Författare :Parashar Dhapola; Avdelningen för molekylär hematologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic Stem Cell; Single-Cell; Genomics; Epigenomics; transcriptomics; bioinformatics;

   Sammanfattning : The focus of this doctoral dissertation was to develop novel and scalable computational genomics methods for analysing single-cell genomic modalities. Scarf, a highly memory-efficient single-cell data analysis toolkit, was developed to enable an analysis of very large-scale datasets on personal computers, and the execution of parallel workflows on server-scale computational systems.

7. 25. How can p53 induce differentiation of leukemic cells?

   Författare :Kristina Drott; Avdelningen för hematologi och transfusionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular fluids; p53-differentiation-p21-WT1-leukemia; Hematologi; Haematology; extracellulära vätskor;

   Sammanfattning : The terminal differentiation of leukemic cells is closely connected to their death. The concept of differentiation therapy originates from the idea that forced maturation of leukemic cells could induce cell death without the side-effects that are provoked by ordinary chemotherapy.
