Preparation, Characterization and In Vitro Anticancer Activity of Sulforaphene-Loaded Solid Lipid Nanoparticles.

Sulforaphane (SFE) extracted from radish seeds has garnered significant research attention in recent years due to its notable biological activities, particularly its anticancer properties. However, SFE is highly sensitive to the environment; therefore, solid lipid nanoparticles (SLNs) were used to embed SFE to enhance its stability. SFE-SLNs were characterized and compared with free SFE to assess the impact of SLNs on SFE.

Development of a surface plasmon resonance biosensing approach for the rapid detection of porcine circovirus type2 in sample solutions.

A sensitive and label-free analytical approach for the detection of porcine circovirus type 2 (PCV2) instead of PCV2 antibody in serum sample was systematically investigated in this research based on surface plasmon resonance (SPR) with an establishment of special molecular identification membrane. The experimental device for constructing the biosensing analyzer is composed of an integrated biosensor, a home-made microfluidic module, and an electrical control circuit incorporated with a photoelectric converter. In order to detect the PCV2 using the surface plasmon resonance immunoassay, the mercaptopropionic acid has been used to bind the Au film in advance through the known form of the strong S-Au covalent bonds formed by the chemical radical of the mercaptopropionic acid and the Au film.

MicroRNA-29a ameliorates glucocorticoid-induced suppression of osteoblast differentiation by regulating β-catenin acetylation.

Excess glucocorticoid treatment induces loss of osteoblast differentiation. Post-translational modification of β-catenin reportedly regulates osteogenic activities in bone cells. This study was undertaken to test whether miR-29a signaling regulates the acetylation status of β-catenin in the glucocorticoid-mediated osteoblast dysfunction.

Cannabinoid receptor 1 mediates glucocorticoid-induced bone loss in rats by perturbing bone mineral acquisition and marrow adipogenesis.

Objective: Prolonged glucocorticoid treatment increases the risk of osteopenic disorders. Bone loss and marrow fat accumulation are prominent features of glucocorticoid-induced skeletal destruction. Cannabinoid receptor 1 (CB(1) ) has been found to regulate energy expenditure and adipose tissue lipogenesis.

Cannabinoid receptor 1 regulates ERK and GSK-3β-dependent glucocorticoid inhibition of osteoblast differentiation in murine MC3T3-E1 cells.

Supraphysiological glucocorticoid administration accelerates loss of survival and differentiation in osteoblastic cells, thereby increasing the risks of osteopenic or osteonecrotic disorders. Neuroendocrine component type 1 cannabinoid receptor (CB1) is found to regulate bone mass. This study characterized the biological role of CB1 in glucocorticoid-induced suppression of osteoblast differentiation.

Heat shock protein 60 protects skeletal tissue against glucocorticoid-induced bone mass loss by regulating osteoblast survival.

Excessive glucocorticoid administration accelerates osteoblast apoptosis and skeletal deterioration. Heat shock proteins (HSPs) regulate metabolic activities in osteoblastic cells. This study characterized the biological significance of HSP60 in glucocorticoid-induced bone loss.
