Sleep-dependent memory consolidation is observed following motor skill learning: Performance improvements are greater over a 12-h period containing sleep relative to an equivalent interval without sleep. Here we examined whether older adults exhibit sleep-dependent consolidation on a sequence learning task. Participants were trained on one of two sequence(More)
The MYC oncogene codes for a transcription factor that is overexpressed in many human cancers. Here we show that MYC regulates the expression of two immune checkpoint proteins on the tumor cell surface: the innate immune regulator CD47 (cluster of differentiation 47) and the adaptive immune checkpoint PD-L1 (programmed death-ligand 1). Suppression of MYC in(More)
In several species caloric restriction (CR) extends lifespan. In this paper we integrate data from studies on CR and other sources to articulate the Hypothalamic Deregulation Hypothesis by which Estrogen Receptor-alpha (ER-α) signaling in the hypothalamus and limbic system affects lifespan under the stress of CR in mammals. ER-α is one of two principal(More)
