Pivotal Role of AKT2 during Dynamic Phenotypic Change of Breast Cancer Stem Cells.

Therapeutic resistance seen in aggressive forms of breast cancer remains challenging for current treatments. More than half of the patients suffer from a disease relapse, most of them with distant metastases. Cancer maintenance, resistance to therapy, and metastatic disease seem to be sustained by the presence of cancer stem cells (CSC) within a tumor.

Safe and neuroprotective vectors for long-term traumatic brain injury gene therapy.

Traumatic brain injury (TBI) is a complex and progressive brain injury with no approved treatments that needs both short- and long-term therapeutic strategies to cope with the variety of physiopathological mechanisms involved. In particular, neuroinflammation is a key process modulating TBI outcome, and the potentiation of these mechanisms by pro-inflammatory gene therapy vectors could contribute to the injury progression. Here, we evaluate in the controlled cortical impact model of TBI, the safety of integrative-deficient lentiviral vectors (IDLVs) or the non-viral HNRK recombinant modular protein/DNA nanovector.
