A Network of 17 Microtubule-Related Genes Highlights Functional Deregulations in Breast Cancer.

A wide panel of microtubule-associated proteins and kinases is involved in coordinated regulation of the microtubule cytoskeleton and may thus represent valuable molecular markers contributing to major cellular pathways deregulated in cancer. We previously identified a panel of 17 microtubule-related (MT-Rel) genes that are differentially expressed in breast tumors showing resistance to taxane-based chemotherapy. In the present study, we evaluated the expression, prognostic value and functional impact of these genes in breast cancer.

[Mitochondrial transport: How does it impact cancer?].

Cancer cells are characterized by a deregulation of their metabolic activity, which allows them to meet a high energy demand. Mitochondria are key organelles that control several metabolic processes and represent the main source of energy in the form of ATP. Intracellular transport of mitochondria is essential for addressing these organelles to the right place at the right time according to energy requirement.
