26302400 elevated levels of CatK are closely associated with the presence of chronic heart failure and that the measurement of circulating CatK provides a noninvasive method of documenting and monitoring the extent of chronic heart failure
26241216 increased expression and activation in osteoarthritis cartilage
26219353 Matrix-metalloproteinase-9 is cleaved and activated by cathepsin K.
25809793 SDF-1alpha is involved in homing of CXCR4+ GSLCs and leukocytes and that cathepsin K and osteopontin are involved in the migration of GSLCs out of the niches
25725806 Sequence analysis of the patient's CTSK gene revealed homozygosity for a missense mutation (c.746T>C) in exon 6, which leads to amino change (p.Ile249Thr) in the mature CTSK protein
25662720 There is an increase in levels of CATK in type 1 Gaucher patients compared to the control group. In the patient group, CATK showed higher levels in patients with bone damage compared to those without it.
25626674 The study determined almost identical substrate specificities for cysteine cathepsins K, L and S.
25558848 Cathepsins in Rotator Cuff Tendinopathy: Identification in Human Chronic Tears and Temporal Induction in a Rat Model.
25422423 one cathepsin K molecule binds to collagen-bound glycosaminoglycans at the gap region and recruits a second protease molecule that provides an unfolding and cleavage mechanism for triple helical collagen
25356585 The presence of high levels of inactive proforms of cathepsin K in GBM tissues and cells indicate that in GBM the proteolytic/collagenolytic role is not its primary function but it plays rather a different yet unknown role.
