CO-releasing binuclear rhodium complexes as inhibitors of nitric oxide generation in stimulated macrophages.

2013

Nontoxic CO-releasing dirhodium complexes act as inhibitors of NO in stimulated macrophage cells, suggesting that novel antiinflammatory treatments could involve the use of these types of binuclear complexes.

Effects of Nrf2 deficiency on bone microarchitecture in an experimental model of osteoporosis

2014

Objective. Redox imbalance contributes to bone fragility. We have evaluated the in vivo role of nuclear factor erythroid derived 2-related factor-2 (Nrf2), an important regulator of cellular responses to oxidative stress, in bone metabolism using a model of postmenopausal osteoporosis. Methods. Ovariectomy was performed in both wild-type and mice deficient in Nrf2 (Nrf2-/-). Bone microarchitecture was analyzed by CT. Serum markers of bone metabolism were also measured. Reactive oxygen species production was determined using dihydrorhodamine 123. Results. Sham-operated or ovariectomized Nrf2 -/- mice exhibit a loss in trabecular bone mineral density in femur, accompanied by a reduction in co…

Heme oxygenase-1 regulates the progression of K/BxN serum transfer arthritis.

2012

Background Heme oxygenase-1 (HO-1) is induced in many cell types as a defense mechanism against stress. We have investigated the possible role of endogenous HO-1 in the effector phase of arthritis using the K/BxN serum transfer model of arthritis in HO-1 heterozygous and homozygous knock-out mice. Methodology/Principal Findings Arthritis was induced in C57/Black-6 xFVB (HO-1+/+, HO-1+/− and HO-1−/−) mice by intraperitoneal injection of 150 µl serum from arthritic K/BxN mice at days 0 and 2. Blood was collected and animals were sacrificed at day 10. Histological analysis was performed in ankle sections. The levels of inflammatory mediators were measured in serum and paw homogenates by enzyme…
