Hyperglycemia in rodent models of type 2 diabetes requires insulin-resistant alpha cells
To determine the role of glucagon action in diet-induced and genetic type 2 diabetes (T2D), we studied high-fat-diet–induced obese (DIO) and leptin receptor-defective (LepR-/-) rodents with and without glucagon receptors (GcgRs). DIO and LepR-/-,GcgR+/+ mice both developed hyperinsulinemia, increased liver sterol response element binding protein 1c, and obesity. DIO GcgR+/+ mice developed mild T2D, whereas […]
Heme Oxygenase-1 Drives Metaflammation and Insulin Resistance in Mouse and Man
Obesity and diabetes affect more than half a billion individuals worldwide. Interestingly, the two conditions do not always coincide and the molecular determinants of “healthy” versus “unhealthy” obesity remain ill-defined. Chronic metabolic inflammation (metaflammation) is believed to be pivotal. Here, we tested a hypothesized anti-inflammatory role for heme oxygenase-1 (HO-1) in the development of metabolic […]
Essential Role of Presynaptic NMDA Receptors in Activity-Dependent BDNF Secretion and Corticostriatal LTP
Activation of N-methyl-D-aspartate subtype of glutamate receptors (NMDARs) in postsynaptic dendrites is required for long-term potentiation (LTP) of many excitatory synapses, but the role of presynaptic axonal NMDARs in synaptic plasticity remains to be clarified. Here we report that axonal NMDARs play an essential role in LTP induction at mouse corticostriatal synapses by triggering activity-induced […]
Atrogin-1 deficiency promotes cardiomyopathy and premature death via impaired autophagy
Cardiomyocyte proteostasis is mediated by the ubiquitin/proteasome system (UPS) and autophagy/lysosome system and is fundamental for cardiac adaptation to both physiologic (e.g., exercise) and pathologic (e.g., pressure overload) stresses. Both the UPS and autophagy/lysosome system exhibit reduced efficiency as a consequence of aging, and dysfunction in these systems is associated with cardiomyopathies. The muscle-specific ubiquitin […]
Exome sequencing identifies somatic gain-of-function PPM1D mutations in brainstem gliomas
Gliomas arising in the brainstem and thalamus are devastating tumors that are difficult to surgically resect. To determine the genetic and epigenetic landscape of these tumors, we performed exomic sequencing of 14 brainstem gliomas (BSGs) and 12 thalamic gliomas. We also performed targeted mutational analysis of an additional 24 such tumors and genome-wide methylation profiling […]
Vascular rarefaction mediates whitening of brown fat in obesity
Brown adipose tissue (BAT) is a highly vascularized organ with abundant mitochondria that produce heat through uncoupled respiration. Obesity is associated with a reduction of BAT function; however, it is unknown how obesity promotes dysfunctional BAT. Here, using a murine model of diet-induced obesity, we determined that obesity causes capillary rarefaction and functional hypoxia in […]
Maintenance of GABAergic Activity by Neuregulin 1-ErbB4 in Amygdala for Fear Memory
Inhibitory neurotransmission in amygdala is important for fear learning and memory. However, mechanisms that control the inhibitory activity in amygdala are not well understood. We provide evidence that neuregulin 1 (NRG1) and its receptor ErbB4 tyrosine kinase are critical for maintaining GABAergic activity in amygdala. Neutralizing endogenous NRG1, inhibition, or genetic ablation of ErbB4, which […]
Neuroprotection through Excitability and mTOR Required in ALS Motoneurons to Delay Disease and Extend Survival
Delaying clinical disease onset would greatly reduce neurodegenerative disease burden, but the mechanisms influencing early preclinical progression are poorly understood. Here, we show that in mouse models of familial motoneuron (MN) disease, SOD1 mutants specifically render vulnerable MNs dependent on endogenous neuroprotection signaling involving excitability and mammalian target of rapamycin (mTOR). The most vulnerable low-excitability […]
