The present study tested the potential effect of OSU53, a novel AMPK activator, against hydrogen peroxide (H2O2)-induced spinal cord neuron damages. Treatment with OSU53 attenuated H2O2-induced death and apoptosis of primary murine spinal cord neurons. OSU53 activated AMPK signaling, which is required for its actions in spinal cord neurons. The AMPK inhibitor Compound C or AMPKα1 siRNA almost a...

Despite its central role in the control of apoptosis, senescence and cell cycle arrest, the tumor suppressor protein p53 remains an enigma for its possible role in predicting response to chemotherapy in cancer patients. Many studies remained inconclusive, others showed a better response for tumors with normal p53, and some recent studies showed adverse effects of normal p53 for response to trea...

The modern concept of the evolution Mars assumes that life could potentially have originated on planet Mars, possibly during end late heavy bombardment, and then be transferred to other planets. Since then, physical chemical conditions changed now strongly limit presence terrestrial-like forms. These adverse include scarcity liquid water (although brine solutions may exist), low temperature atm...
