Current therapies for Traumatic brain injury (TBI) focus on stabilizing individuals and on preventing further damage from the secondary consequences of TBI. A major complication of TBI is cerebral edema, which can be caused by the loss of blood...

Metabolic network motifs can provide novel insights into evolution: The evolutionary origin of Eukaryotic organelles as a case study.

Computational biology and chemistry

Phylogenetic trees are typically constructed using genetic and genomic data, and provide robust evolutionary relationships of species from the genomic point of view. We present an application of network motif mining and analysis of metabolic pathways that when used...

Identification of a neurovascular signaling pathway regulating seizures in mice.

Annals of clinical and translational neurology

Ann Clin Transl Neurol. 2015 Jul;2(7):722-38. doi: 10.1002/acn3.209. Epub 2015 May 01.

OBJECTIVE: A growing body of evidence suggests that increased blood-brain barrier (BBB) permeability can contribute to the development of seizures. The protease tissue plasminogen activator (tPA) has been shown to promote BBB permeability and susceptibility to seizures. In this...

Diet-induced obesity promotes myelopoiesis in hematopoietic stem cells.

Molecular metabolism

Mol Metab. 2014 Jul 10;3(6):664-75. doi: 10.1016/j.molmet.2014.06.005. eCollection 2014 Sep.

Obesity is associated with an activated macrophage phenotype in multiple tissues that contributes to tissue inflammation and metabolic disease. To evaluate the mechanisms by which obesity potentiates myeloid activation, we evaluated the hypothesis that obesity activates myeloid cell production...

TRAP-seq defines markers for novel populations of hypothalamic and brainstem LepRb neurons.

Molecular metabolism

Mol Metab. 2015 Feb 07;4(4):299-309. doi: 10.1016/j.molmet.2015.01.012. eCollection 2015 Apr.

OBJECTIVE: Leptin acts via its receptor (LepRb) on multiple subpopulations of LepRb neurons in the brain, each of which controls specific aspects of energy balance. Despite the importance of LepRb-containing neurons, the transcriptome and molecular identity of many LepRb...

Perceptive costs of reproduction drive ageing and physiology in male Drosophila.

Nature ecology & evolution

Harvanek ZM, Lyu Y, Gendron CM, Johnson JC, Kondo S, Promislow DEL, Pletcher SD.
PMID: 28812624
Nat Ecol Evol. 2017 May 15;1(6):152. doi: 10.1038/s41559-017-0152.

Costs of reproduction are thought to result from natural selection optimizing organismal fitness within putative physiological constraints. Phenotypic and population genetic studies of reproductive costs are plentiful across taxa, but an understanding of their mechanistic basis would provide important...

Concurrent activation of growth factor and nutrient arms of mTORC1 induces oxidative liver injury.

Cell discovery

Cho CS, Kowalsky AH, Namkoong S, Park SR, Wu S, Kim B, James A, Gu B, Semple IA, Tohamy MA, Solanki S, Cho US, Greenson JK, Shah YM, Kim M, Lee JH.

Cell Discov. 2019 Nov 19;5:60. doi: 10.1038/s41421-019-0131-9. eCollection 2019.

mTORC1 is a protein kinase important for metabolism and is regulated by growth factor and nutrient signaling pathways, mediated by the Rheb and Rag GTPases, respectively. Here we provide the first animal model in which both pathways were upregulated...

Persistent epigenetic reprogramming of sweet taste by diet.

Diets rich in sugar, salt, and fat alter taste perception and food preference, contributing to obesity and metabolic disorders, but the molecular mechanisms through which this occurs are unknown. Here, we show that in response to a high sugar...

Reprogramming the body weight set point by a reciprocal interaction of hypothalamic leptin sensitivity and Pomc gene expression reverts extreme obesity.

Molecular metabolism

OBJECTIVE: A major challenge for obesity treatment is the maintenance of reduced body weight. Diet-induced obese mice are resistant to achieving normoweight once the obesogenic conditions are reversed, in part because lowered circulating leptin leads to a reduction in...

Brain on food: The neuroepigenetics of nutrition.
