  1. 1. Molecular mechanisms of nerve-tumor interactions : the intersection of cancer and neurodevelopment

    Author : Luz Maria Gonzalez-Castrillon; Sara I Wilson; Daniel Öhlund; Nisha D’Silva; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Perineural invasion; cancer; PDAC; axonogenesis; neurodevelopment; spinal cord; axon guidance; bioinformatics.; biomedical laboratory science; biomedicinsk laboratorievetenskap;

    Abstract : A wide range of cancers throughout the body are characterized by high nerve density and invasion of cancer cells within the nerves, a process called perineural invasion (PNI). Work in the field has shown that blocking nerves in organs with tumors leads to improved disease outcomes suggesting that finding ways to block tumor nerves could lead to new treatment approaches.

  2. 2. Hereditary Nonpolyposis Colorectal Cancer - Molecular Genetics and Biology of Associated Tumors

    Author : Maria Planck; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endometrial cancer; rectal cancer; colon cancer; mismatch repair protein expression; coding repeats; microsatellite instability; MSH6; MSH2; Hereditary nonpolyposis colorectal cancer; MLH1; small bowel cancer; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

    Abstract : This thesis focuses on one of the most common types of hereditary cancer, hereditary nonpolyposis colorectal cancer (HNPCC). This syndrome is characterized by an autosomal dominant inheritance, an increased risk for several types of cancer (especially cancer of the colorectum, small bowel, endometrium, ovary and urinary tract), early age at diagnosis, and frequent development of multiple primary malignancies.

  3. 3. Cancer and Inflammation : Role of Macrophages and Monocytes

    Author : Alexander Hedbrant; Jonny Wijkander; Dick Delbro; Ann Erlandsson; Anita Sjölander; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; M1 macrophages; M2 macrophages; colon cancer; lung cancer; prostaglandin E2; Biomedical Sciences; Biomedicinsk vetenskap;

    Abstract : Macrophages are cells of the innate immune system that can be found in large quantities in cancer tumors and affect cancer progression by regulating growth and invasiveness of cancer cells. There are two main phenotypes of macrophages denoted M1 and M2. READ MORE

  4. 4. Computational exploration of cancer genomes

    Author : Joakim Karlsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cancer genomics; Transcriptomics; Driver genes; Copy number changes; Immunogenomics; Cancer of unknown primary; Uveal melanoma;

    Abstract : Cancer evolves due to changes in DNA that give a cell an advantage at the expense of the remaining organism. These alterations range from individual base substitutions to broad losses or duplications of chromosomal material. READ MORE

  5. 5. Functional and Molecular Characterization of BRCA1 and BRCA2 Associated Breast Cancer

    Author : Johan Vallon-Christersson; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; onkologi; cancer; Cytologi; cancerology; Cytology; BioArray Software Environment; BASE; Software; Open-source; Copy number; Gene expression; Microarray; BRCA2; BRCA1; Breast cancer; Hereditary cancer; oncology;

    Abstract : This doctoral dissertation is based on five appended papers primarily concerned with three main topics, namely: the functional characterization of specific and clinically relevant perturbations found in BRCA1 ? one of the major breast cancer susceptibility genes; the use of microarray technologies for molecular characterization of hereditary breast tumor samples from a genomic perspective; and finally, the development of software to address some of the logistical problems of data analysis and management that arise when utilizing microarrays. Results obtained from the work presented herein demonstrate the following: that transcription az says can aid in the characterization of C-terminal missense mutations but that it may not be possible to unambiguously characterize variants with a yeast-based assay alone; that a naturally occurring C-terminal germline mutation in BRCA1 encodes a protein with apparent temperature-dependant functional properties; that open-source software can provide comprehensive solutions to meet data management needs of microarray experimenters; that BRCA1 and BRCA2 associated breast tumors exhibit markedly different copy number aberrations when compared to each other as well as to sporadic tumors; and that gene expression profiling in BRCA1 and BRCA2 associated breast tumors reveals specific gene expression patterns.
