The functions of bone (s) are ( i) mechanical support of soft tissues, ( ii) levers for muscle action, ( iii) protection of the central nervous system, ( iv) release of calcium and other ions for the maintenance of a constant ionic environment in the extracellular fluid, and ( v) housing and support of hemopoiesis. Web28 jan. 2024 · In addition, cancer cells modify their MAMs, which consequently affects calcium homeostasis to support mesenchymal transformation, migration, invasiveness, metastasis and autophagy. Alterations in calcium homeostasis may also support resistance to apoptosis, which is a serious problem facing current chemotherapeutic treatments.
