A compound that prevents stressors such as UV light and viral infection from downregulating protein synthesis inside cells improves memory performance in mice.
C-terminal phosphorylation of the lipid phosphatase PTEN drives a reduction in membrane affinity and leads to a more compact conformation that involves a C2 domain-tail interaction.

Nutrient limitation elicits differential responses in cells lacking the tumor suppressor PTEN and in normal cells, resulting in hyperplastic overgrowth of PTEN mutant tissue independent of additional mutations.
By comparing gene expression in people before and after they received the influenza vaccine, researchers were able to identify genes that contribute to differences in individual responses to vaccination.
Hundreds of cell growth and stress response genes are controlled by a rare small RNA component of an ancient splicing machinery, providing a raison d'être for its previously unexplained evolutionary conservation.

The proteins Bax and Bak, which increase the permeability of the mitochondrial membrane during apoptosis, are also crucial for generating a mitochondrial membrane pore that is specifically involved in necrosis.
