Protective effect of polyphenols from berries of Aronia melanocarpa against low exposure to cadmium-induced imbalance in the RANK/RANKL/OPG system in the bone tissue of rats

Rogalska Joanna , Malgorzata M Brzoska

Epidemiological and experimental data indicates that cadmium creates a risk of bone damage even at low exposure. Our recent findings suggest that this heavy metal may affect bone via destroying the receptor activator of nuclear factor (NF)-κβ (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) system balance that plays a key role in the regulation of bone metabolism. The aim of this study was to investigate whether low-level exposure to cadmium, corresponding to low lif...

Protective effect of polyphenols from Aronia melanocarpa berries against cadmium-induced weakening of the femur biomechanical properties in rats

Brzoska Malgorzata M , Roszczenko Alicja , Rogalska Joanna

Bone damage is one of the main unfavourable health effects of chronic exposure to cadmium (Cd). This heavy metal stimulates osteoclastic bone resorption and inhibits osteoblastic bone formation resulting in decreased bone mineralization and as a result weakening of the bone biomechanical properties. Recently, using a rat model of chronic human exposure to cadmium, we have revealed that even low exposure to this metal may increase bone vulnerability to fracture. Taking into acc...

Polyphenols from berries of Aronia melanocarpa improve the antioxidative capacity of the bone tissue in cadmium-exposed rats

Cadmium is characterized by oxidative properties and this heavy metal-induced oxidative stress has been recognized to be involved in its injurious impact on the skeleton. Oxidative/reductive processes are an integral component of bone remodeling; however, destroying of the bone tissue oxidative/antioxidative status with excessive production and accumulation of reactive oxygen species has detrimental impact on bone metabolism. Thus, the aim of this study was to investigate whet...
