Osteoporosis is a systemic skeletal disorder characterized by reduced bone mass and deterioration of bone microarchitecture, which results in increased bone fragility and fracture risk. Casein kinase 2-interacting protein-1 (CKIP-1) is a protein that plays an important role in regulation of bone formation. The effect of CKIP-1 on bone formation is mainly mediated through negative regulation of the bone morphogenetic protein pathway. In addition, CKIP-1 has an important role in the progression of osteoporosis. This review provides a summary of the recent studies on the role of CKIP-1 in osteoporosis development and treatment.
Ligaments which heal spontaneously have a healing process that
is similar to skin wound healing. Menopause impairs skin wound healing
and may likewise impair ligament healing. Our purpose in this study
was to investigate the effect of surgical menopause on ligament
healing in a rabbit medial collateral ligament model. Surgical menopause was induced with ovariohysterectomy surgery
in adult female rabbits. Ligament injury was created by making a
surgical gap in the midsubstance of the medial collateral ligament.
Ligaments were allowed to heal for six or 14 weeks in the presence
or absence of oestrogen before being compared with uninjured ligaments. Molecular
assessment examined the messenger ribonucleic acid levels for collagens,
proteoglycans, proteinases, hormone receptors, growth factors and
inflammatory mediators. Mechanical assessments examined ligament
laxity, total creep strain and failure stress.Objectives
