  1. 1. Osteoprotegerin in Bone Metabolism

    Author : Helena Brändström; Uppsala universitet; []
    Keywords : Medical sciences; Bone; osteoprotegerin; osteoblasts; polymorphism; cytokines; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Abstract : Bone turnover, remodeling, is a constant process replacing old bone with new. This complex cellular event involves resorption by osteoclasts and formation of new bone by osteoblasts. The balance between osteoblastic and osteoclastic activity is under regulation by several endocrine and paracrine factors. READ MORE

  2. 2. On the Role of Osteoprotegerin/RANK/RANKL System in the Interaction between Prostate Cancer and Bone

    Author : Hendrik Penno; Östen Ljunggren; Olof Nilsson; Andreas Kindmark; Pernilla Lundberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metastases; bone; prostate cancer; osteoprotegerin; RANKL; osteoporosis; genetics; polymorphisms; Orthopaedics; Ortopedi;

    Abstract : Metastases to bone are observed in around 80% of prostate cancer patients and represent the most critical complication of advanced prostate cancer. Unlike other solid tumors that are associated with osteolytic bone metastases, prostate cancer bone metastases stimulate osteoblastic activity with sclerosis in the bone lesions as a consequence.

  3. 3. Cellular and molecular responses of periodontal connective tissue cells to Actinobacillus actinomycetemcomitans cytolethal distending toxin

    Author : Georgios N. Belibasakis; Sotirios Kalfas; Ulf H. Lerner; Anders Johansson; Veli-Jukka Uitto; Umeå universitet; []
    Keywords : Medical sciences; Actinobacillus actinomycetemcomitans; cytolethal distending toxin; periodontal connective tissue cells; localized aggressive periodontitis; growth arrest; bone resorption; receptor activator of NF-κB ligand; osteoprotegerin; pro-inflammatory cytokines; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; odontologi; Odontology;

    Abstract : Actinobacillus actinomycetemcomitans is present in elevated proportions and numbers in dental bacterial biofilms of patients with localized aggressive periodontitis. This variant of periodontal disease, occurring in adolescents and young adults, is characterized by rapid and severe destruction of the connective tissues and bone supporting the teeth, eventually culminating in tooth loss.

  4. 4. Atherosclerotic cardiovascular disease in rheumatoid arthritis : aspects of pathogenesis and risk

    Author : Bengt Wahlin; Solveig Wållberg-Jonsson; Anna Södergren; Anders Bengtsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rheumatoid arthritis; inflammation; atherosclerosis; cardiovascular disease; risk estimation; cytomegalovirus; T-cells; bone turnover; osteoprotegerin; osteocalcin; Medicine; medicin;

    Abstract : Patients with rheumatoid arthritis (RA) have an increased prevalence and severity of atherosclerosis, and a corresponding increased risk of cardiovascular disease. The mechanisms causing this are not well elucidated, but both traditional cardiovascular risk factors and RA-associated factors have been associated with atherosclerosis and increased risk of cardiovascular events in patients with RA.

  5. 5. Studies of molecular mechanisms of action of TNF antagonists in rheumatoid arthritis

    Author : Anca Irinel Catrina; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Rheumatoid arthritis; TNF antagonists; cytokines; macrophages; matrix metalloproteinases; osteoprotegerin; RANKL; apoptosis;

    Abstract : Rheumatoid arthritis (RA) is a common chronic inflammatory disease characterized by progressive bone destruction that leads to joint deformity and physical disability. Even though several therapeutic drugs are available, none have emerged as an ideal RA treatment that delays joint destruction and halts disease progression. READ MORE
