1. 1. Molecular and Cellular Complexity of Glioma : Highlights on the Double-Edged-Sword of Infiltration Versus Proliferation and the Involvement of T Cells

   Författare :Demet Çağlayan; Bengt Westermark; Maria Ferletta; Ana Martin-Villalba; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glioma; Sox2; Sox21; Snail; Bone morphogenetic protein; Sleeping Beauty; Gliomatosis Cerebri; T lymphocytes; T regulatory lymphocytes; Oncology; Onkologi; Biology; Biologi;

   Sammanfattning : Glioblastoma multiforme (GBM), the most common and malignant brain tumor, is characterized by high molecular and cellular heterogeneity within and among tumors. Parameters such as invasive growth, infiltration of immune cells and endothelial proliferation contribute in a systemic manner to maintain the malignancy. LÄS MER

3. 2. Influence of neuromodulators and mechanical loading on pathological cell and tissue characteristics in tendinosis

   Författare :Gloria Fong; Patrik Danielson; Alex Scott; Ludvig Backman; Paul Ackermann; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; substance P; acetylcholine; transforming growth factor; neuromodulators; mechanical loading; tendinosis; anatomi; Human Anatomy;

   Sammanfattning : Background: Tendinosis is a painful chronic, degenerative condition characterized by objective changes in the tissue structure of a tendon. Hallmark features in tendinosis tendons include increased number of cells (hypercellularity), extracellular matrix (ECM) degradation and disorganized collagen. LÄS MER

4. 3. Neuropilin-1 regulation of tumor vascularization and growth

   Författare :Eric Morin; Lena Claesson-Welsh; Hellmut Augustin; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; Neuropilin-1; VEGFR2; tumor biology; pancreatic ductal adenocarcinoma; renal cell carcinoma; Medical Cell Biology; Medicinsk cellbiologi;

   Sammanfattning : Angiogenesis, the formation of new blood vessels from existing ones, is dysregulated during tumor progression as a result of chronic hypoxia and inflammation. Such alterations lead to a lack of vessel hierarchy, and the formation of poorly perfused, leaky and blunt-ended vessels, contributing to disease progression. LÄS MER

5. 4. Mast Cell-Mediated Orchestration of Airway Epithelial Responses in Chronic Respiratory Diseases

   Författare :Frida Berlin; Respiratorisk cellbiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mast cell; Tryptase; Chymase; Bronchial epithelium; Respiratory diseases;

   Sammanfattning : Chronic respiratory diseases, such as asthma, are an increasing health issue worldwide and cause about 3.9 million deaths annually. Despite this, little is know about the molecular mechanisms underpinning disease pathogenesis. LÄS MER

7. 5. Improvements of the Bromodeoxyuridine-DNA Flow Cytometry Method for the Study of Cell Proliferation

   Författare :Maria C Johansson; Bröstcancer-genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; head and neck cancer; [3H]thymidine; energy transfer; cell cycle; xenografted tumours; cultured cells; potential doubling time; labelling index; DNA synthesis time; cell proliferation; growth kinetics; Bromodeoxyuridine; DNA flow cytometry; cancer; onkologi; Cytologi; cancerology; oncology; Cytology;

   Sammanfattning : Potential doubling time (Tpot), DNA synthesis time (TS), and labelling index (LI) are fundamental growth kinetics parameters in clinical and experimental cancer research, which may be of further practical importance regarding prognosis and treatment prediction of cancer. They can be measured by bromodeoxyuridine(BrdUrd)/flow cytometry (FCM) methods, where BrdUrd, an analogue of thymidine, is incorporated into DNA and quantified simultaneously with the DNA content.
