Total RNA was isolated from 3 WT and 3 ERRa null hearts and independent hybridizations were performed using MOE430 2.0 microarrays. Expression profiling was conducted to determine changes in gene expression in hearts lacking ERRa. The expression of genes involved in heart and muscle development, muscle contraction, lipid metabolism, OxPhos, protein metabolism and transcription were affected by the loss of ERRa.

View SamplesNeurons utilize glucose to generate adenosine triphosphate (ATP) essential for their survival, excitability and synaptic signaling, as well as initiating changes in neuronal structure and function. Defects in oxidative metabolism and mitochondria functions are also associated with aging and diverse human neurological diseases1-4. While neurons are known to adapt their metabolism to meet the increased energy demands of complex behaviors such as learning and memory, the molecular underpinnings regulating this process remain poorly understood4-6. Here we show that the orphan nuclear receptor estrogen related receptor gamma (ERR) becomes highly expressed during retinoic-acid induced neurogenesis and is widely expressed in neuronal nuclei throughout the brain. Mechanistically, we show that ERR directly orchestrates the expression of networks of genes involved in mitochondrial oxidative phosphorylation and energy generation in neurons. The importance of this regulation is evidenced by decreased adaptive metabolic capacity in cultured neurons lacking ERR, and reduced long-term potentiation (LTP) in ERR-/- hippocampal slices. Notably, the defect in LTP was rescued by the metabolic intermediate pyruvate, functionally linking the ERR knockout metabolic phenotype and memory formation. Consistent with this notion, mice lacking neuronal ERR exhibit defects in spatial learning and memory. These findings implicate ERR in the metabolic adaptations required for long-term memory formation.

View SamplesWe synthesized the PAX8-NFE2L2 fusion transcript and cloned it into a lentiviral vector, and used this to overexpress it in the murine prostate adenocarcinoma cell line TRAMP-C1. Overall design: We used high coverage RNA sequencing (>30 million reads per sample) to compare the expression profiles of cells expressing the PAX8-NFE2L2 fusion transcript to cells transduced with an empty vector.

View SamplesSome of the functions and mechanisms of PPAR?-mediated regulation of vascular homeostasis have been revealed, the potential role of PPAR? in angiogenesis is obscure. In human ECs, PPAR?-deficiency was studied using siRNA strategy and RNA sequencing was utilized to reveal angiogenesis-associated targets for PPARg. Overall design: Our aim is to reveal the possible role of PPARy in angiogenesis.

View SamplesDevelopmental transitions can be described in terms of morphology and individual genes expression patterns, but also in terms of global transcriptional and epigenetic changes. Most of the large-scale studies of such transitions, however, have only been possible in synchronized cell culture systems. Here we generate a cell type specific transcriptome of an adult stem-cell lineage in the Arabidopsis leaf using RNA sequencing and microarrays. RNA profiles of stomatal entry, commitment, and differentiating cells, as well as of mature stomata and the entire aerial epidermis give a comprehensive view of the developmental progression.
Transcriptome dynamics of the stomatal lineage: birth, amplification, and termination of a self-renewing population.
