This analysis reveals how nutrient stress influences lysosomal function in metastatic breast cancer, indicating a crucial metabolic adaptation during EMT.
Key Points
Invasive cancer cells use lysosomes for nutrient scavenging, supporting survival during amino acid deprivation.
The metabolic switch that aids cell invasion is linked to c-MYC downregulation and heightened macropinocytosis.
Understanding the balance between proliferation and invasion provides insights into breast cancer metastasis.
EMT triggers an endolysosomal system upregulation that facilitates adjustments in cellular metabolism.
