PURPOSE To investigate the protective effects of cobalt protoporphyrin (CoPP), a potent heme oxygenase (HO)-1 inducer, in a rat model of ischemia-reperfusion injury and to document the possible antiapoptotic and anti-inflammatory mechanisms underlying the protection. METHODS Rats pretreated with intraperitoneal injection of CoPP (5 mg/kg) were subjected(More)
Symptomatic tendinopathy tends to be age-related. However, the molecular mechanisms of ageing and its effects on tenocyte proliferation and cell cycle progression are unknown. We examined tenocytes from Achilles tendons in rats from three age groups (young, 2 months; middle-aged, 12 months, and near senescence, 24 months). Tenocyte proliferation was(More)
Pancreatic cancer (PDA) is a devastating disease and there is no effective treatment available at present. To develop new regiments against PDA is urgently needed. Previously we have shown that vitamin D analog, MART-10 (19-nor-2α-(3-hydroxypropyl)-1α,25(OH)2D3), exerted potent antiproliferative effect on PDA in vitro and in vivo without causing(More)
Pentadecapeptide BPC 157, composed of 15 amino acids, is a partial sequence of body protection compound (BPC) that is discovered in and isolated from human gastric juice. Experimentally it has been demonstrated to accelerate the healing of many different wounds, including transected rat Achilles tendon. This study was designed to investigate the potential(More)
BACKGROUND Thrombosis is the dominant cause of failure of arteriovenous fistulas for hemodialysis access. Vascular inflammation, an important pathologic change in various human vascular diseases, may be involved in the thrombotic process of arteriovenous fistulas. METHODS The inflammatory activities of 23 thrombosed and 13 non-thrombosed stenotic(More)
Sports-related tendon injuries are commonly treated with nonsteroidal antiinflammatory drugs. This study was designed to determine the in vitro effect of ibuprofen on the proliferation of tendon cells intrinsic to rat Achilles tendon. Furthermore, the existence of a correlation between this effect and the expression of the cyclin kinase inhibitor p21(CIP1)(More)
Ciprofloxacin-induced tendinopathy and tendon rupture have been previously described, principally affecting the Achilles tendon. This study was designed to investigate the effect of ciprofloxacin on expressions of matrix metalloproteinases (MMP)-2 and -9, tissue inhibitors of metalloproteinase (TIMP)-1 and -2 as well as type I collagen in tendon cells.(More)
We investigated whether thrombin, the final activator of coagulation cascade, regulates expression of matrix metalloproteinases (MMP)-9 in human monocytes. We show that thrombin stimulation induced MMP-9 secretion of monocytes dose- and time-dependently as revealed by gelatin zymography. Real-time RT-PCR and Western blot analysis demonstrated that thrombin(More)
BACKGROUND The effect of percutaneous transluminal angioplasty (PTA) in the treatment of hemodialysis vascular access stenosis is attenuated by a high restenosis rate, which results mainly from neointimal hyperplasia. Cellular proliferation is one of the most important biological mechanisms involved in neointimal hyperplasia and may be a potential target of(More)
Regarding breast cancer treatment, triple negative breast cancer (TNBC) is a difficult issue. Most TNBC patients die of cancer metastasis. Thus, to develop a new regimen to attenuate TNBC metastatic potential is urgently needed. MART-10 (19-nor-2α-(3-hydroxypropyl)-1α,25(OH)₂D₃), the newly-synthesized 1α,25(OH)₂D₃ analog, has been shown to be much more(More)
