Mechanism of Interleukin-17A Regulation of Mesenchymal Stroma/Stem Cell Osteogenic Differentiation.

The immune and musculoskeletal systems closely interplay in bone repair and regeneration. After bone injury, the body produces high levels of cytokines and signaling molecules to balance bone formation and resorption. Interleukin (IL)-17A, a cytokine expressed early in the inflammatory process, profoundly influences osteoprogenitor cell fate, thereby contributing to bone homeostasis.

An evaluation of the cytotoxic potential of medicinal mushrooms against human breast cancer cell lines.

Medicinal mushroom extracts, i.e. their dried biomass, have long been known as sources of bioactive compounds with positive effects on the human health.

Hydroxyurea inhibits proliferation and stimulates apoptosis through inducible nitric oxide synthase in erythroid cells.

Hydroxyurea (hydroxycarbamide, HU) arrests cells in the S-phase by inhibiting ribonucleotide reductase and DNA synthesis, significantly contributing to the release of nitric oxide (NO). We investigated the involvement of inducible NO synthase (NOS2) in the cytostatic effect of HU using in vitro shRNA-induced knockdown of the NOS2 transcript (NOS2) or a specific NOS2 inhibitor (1400W) in human erythroleukemic HEL92.1.

Development of Novel ROCK Inhibitors via 3D-QSAR and Molecular Docking Studies: A Framework for Multi-Target Drug Design.

Alterations in the actin cytoskeleton correlates to tumor progression and affect critical cellular processes such as adhesion, migration and invasion. Rho-associated coiled-coil-containing protein kinases (ROCK1 and ROCK2), important regulators of the actin cytoskeleton, are frequently overexpressed in various malignancies. The aim of this study was therefore to identify the key structural features of ROCK1/ROCK2 inhibitors using computer-aided drug design (CADD) approaches.
