Fig. 2: Key pro-apoptotic and anti-apoptotic pathways in osteocytes under different pathological conditions.
From: Osteocyte apoptosis: the roles and key molecular mechanisms in resorption-related bone diseases

These signaling pathways, including pro-apoptotic pathways (red arrows) and anti-apoptotic pathways (green arrows), are closely related to increased bone resorption and decreased bone formation.
