Significance of Molecular Chaperones
Molecular chaperones play a crucial role in regulating the stability and function of tumor suppressor proteins, which are essential for preventing tumorigenesis. These proteins, which can suppress metastasis, require proper chaperoning to maintain their necessary protein levels for normal function. Disruption in the chaperoning process due to mutations can lead to oncogenesis, highlighting the importance of chaperones such as HSP70 and HSP90 in cancer biology. The review emphasizes that the relationship between molecular chaperones and tumor suppressors is vital for understanding cancer development and potential therapeutic interventions.
