  1. 1. Basement membrane collagens in pancreatic cancer : novel stroma-derived tumor markers and regulators of cancer cell growth

    Författare :Daniel Öhlund; Malin Sund; Peter Naredi; Matthias Löhr; Umeå universitet; []
    Nyckelord :Pancreatic cancer; tumor marker; basement membrane; type IV collagen; type XVIII collagen; matrix metalloproteinase; integrin; autocrine loop; tumor stroma; kirurgi; Surgery;

    Sammanfattning : Background: Among the common malignancies, pancreatic cancer has the shortest long-term survival. The aggressive, rapid, and infiltrative growth pattern of pancreatic cancer, together with the lack of specific symptoms, often leads to late diagnosis. LÄS MER

  3. 2. The identification and functional evaluation of novel cancer-associated fibroblast subtypes and matrisome proteins in pancreatic cancer

    Författare :Joshua Cumming; Daniel Öhlund; Cedric Patthey; Jenny Persson; Claus Jørgensen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer-associated fibroblast CAF ; Single-cell RNA sequencing scRNAseq ; Pancreatic ductal adenocarcinoma PDAC ; Tumor microenvironment TME ; Extracellular matrix ECM ; Organoid-based co-culture model; Drug-screen; Oncology; onkologi;

    Sammanfattning : Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal malignancy characterized by an extensive desmoplastic stroma. The stroma is the site of intricate communication between malignant cells and their surrounding environment. LÄS MER

  4. 3. Stromal components and micro-RNAs as biomarkers in pancreatic cancer

    Författare :Oskar Franklin; Malin Sund; Daniel Öhlund; Ola Billing; Marco Del Chiaro; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pancreatic cancer; stroma; basement membrane; tumour markers; type IV collagen; endostatin; osteopontin; tenascin c; hyaluronan; CD44; micro-RNA; kirurgi; Surgery;

    Sammanfattning : Background Pancreatic ductal adenocarcinoma (PDAC) patients have the poorest 5-year survival rates of all cancer forms. It is difficult to diagnose at early disease stages, tumour relapse after surgery is common, and current chemotherapies are ineffective. LÄS MER

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

    Författare :Luz Maria Gonzalez-Castrillon; Sara I Wilson; Daniel Öhlund; Nisha D’Silva; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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.

  7. 5. The role of stroma-derived substances in breast cancer progression and their function as tumour markers

    Författare :Malin Jansson; Malin Sund; Daniel Öhlund; Ola Billing; Emma Niméus; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; perlecan; type IV collagen; type I collagen; extracellular matrix; tumour biomarkers; Surgery; kirurgi;

    Sammanfattning : Background: In 2020, more than 2,260,000 women were diagnosed with breast cancer. Most patients are cured with surgery and adjuvant treatment, but despite that, approximately 700,000 women die of the disease every year. The historical focus on breast cancer progression has been on the malignant epithelial cell. LÄS MER
