miR-139-5p suppresses cancer cell migration and invasion through targeting ZEB1 and ZEB2 in GBM.

Invasion and migration of glioblastoma multiforme (GBM) is a multistep process and an important phenotype that causes this disease to invade surrounding tissues in the brain. Recent studies have highlighted that miRNAs play a pivotal role in controlling GBM cell plasticity. In this report, we used wound healing and transwell assays to identify a novel role of miR-139-5p in inhibition of GBM cell migration and invasion.

Regular treadmill running improves spatial learning and memory performance in young mice through increased hippocampal neurogenesis and decreased stress.

A substantial amount of evidence has shown that treadmill running enhances neurogenesis, improves cognitive function, and protects the brain against neurodegenerative disorders. However, treadmill running is a type of forced exercise that could increase the level of corticosterone, which subsequently down-regulates neurogenesis and impairs cognitive function. The purpose of this study was to investigate if regular treadmill running provides a balance between the positive and negative effects of treadmill running.
