Loss of renal tubular PGC-1α exacerbates diet-induced renal steatosis and age-related urinary sodium excretion in mice

(Submitter supplied) The kidney has a high energy demand and is dependent on oxidative metabolism for ATP production. Accordingly, the kidney is rich in mitochondria, and mitochondrial dysfunction is a common denominator for several renal diseases. While the mitochondrial master regulator peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) is highly expressed in kidney, its role in renal physiology is so far unclear. more...

Mouse kidney after systemic endotoxin challenge

(Submitter supplied) 8 week-old male C57BL6J mice were given Gram-negative endotoxin (LPS O111:B4, 10 mg/kg) intraperitoneally at time 0. 18 hrs thereafter, they were administered 10 ml/kg 0.9% saline. Mice were sacrificed at 0, 18, or 42 hrs after LPS challenge. Kidneys were immediately collected into TRIzol for RNA preparation. Renal function was measured on blood collected at the time of tissue harvest At t=0hr, mice had normal baseline renal function. more...

Skeletal muscle PGC-1a mediates mitochondrial, but not metabolic, changes during calorie restriction.

(Submitter supplied) Calorie restriction (CR) is a dietary intervention that extends lifespan and healthspan in a variety of organisms. CR improves mitochondrial energy production, fuel oxidation and reactive oxygen species scavenging in skeletal muscle and other tissues, and these processes are thought to be critical to the benefits of CR. PGC-1a is a transcriptional coactivator that regulates mitochondrial function and is induced by CR. more...

lipin 1beta overexpression in mouse liver

(Submitter supplied) Mutations in the gene encoding lipin 1 cause hepatic steatosis in fld mice, a genetic model of lipodystrophy. Lipin 1 appears to be highly involved in the control of fatty acid metabolism. Lipin 1 is most often located in the nucleus, but other studies suggest that lipin also has effects in the cytoplasm. However, the molecular function of lipin 1 is unclear. To evaluate the effects of activation of the lipin 1 system in liver, lipin 1beta was overexpressed in mouse liver using an adenoviral vector. more...

Lipin 1-beta overexpression effect on the liver

Analysis of livers of transgenics overexpressing lipin 1-beta, an alternative form of lipin 1 containing a 33 amino acid insertion. Mutations in the gene encoding lipin 1 cause hepatic steatosis in fld animals, a genetic model of lipodystrophy. Results provide insight into the function of lipin 1.

Progressive loss of PGC-1alpha expression in aging muscle potentiates glucose intolerance and systemic inflammation

(Submitter supplied) Decreased mitochondrial mass and function in muscle of diabetic patients is associated with low PGC-1alpha, a transcriptional coactivator of the mitochondrial gene program. To investigate whether reduced PGC-1alpha and oxidative capacity in muscle directly contributes to age-related glucose intolerance, we compared the genetic signatures and metabolic profiles of aging mice lacking muscle PGC-1alpha. more...

Peroxisome proliferator-γ coactivator-1α deficiency effect on aged gastrocnemius muscle

Analysis of muscle from aged animals with muscle-specific Pgc-1α depletion. PGC-1alpha is a transcriptional coactivator of the mitochondrial gene program. Results provide insight into the role of Pgc-1α in the glucose intolerance and chronic systemic inflammation associated with aging.

ChIPSeq data from melanoma cancer cell line CHL-1 after Bromodomain and extra terminal (Bet) domain inhibitor treatment

(Submitter supplied) Bromodomain and extra terminal domain (BET) inhibition reduces occupancy of BET-family proteins at promoter and enhancer sites finally leading to genome wide changes in gene transcription. We used ChIPSeq profiling to investigate genome wide changes in promoter and enhancer occupancy induced by BET inhibitors BAY 1238097 and OTX-015, respectively.

Effects of Peroxisome proliferator-γ coactivator-1α (PGC-1a) isoform over-expression +/- TNFalpha on hepatocyte gene expression

(Submitter supplied) PGC-1a is a transcriptional coactivator known to regulate a broad gene program of nutrient and mitochondrial metabolism. Many splice variants of this protein have been identified, but their functions were unknown. This experiment was designed to delineate the downstream targets of two different PGC-1alpha isoforms (PGC-1a1 and PGC-1a4) in hepatocytes, and to determine whether inflammatory signaling (via TNFR activation) modulated these targets Liver is exposed to constantly changing metabolic and inflammatory environments. more...

Expression data from lung metastatic explants

(Submitter supplied) The role of PGC1alpha in breast cancer lung metastasis is largely unknown. We used expression data from lung metastatic explants overexpressing PGC1alpha or control, treated with phenformin to understand global gene expression changes which occur in a PGC1alpha context and under phenformin treatment. We used expression data to understand the pathways and genes that may lead to lung metastasis in a PGC1alpha overexpression setting.

Expression data from a human lung metastatic cell line treated with siPGC1alpha or siControl

(Submitter supplied) To understand global expression changes in a knockdown of PGC1alpha (siPGC1alpha) vs control (siControl) in a lung metastatic cell line (4175) Metabolic adaptations play a key role in fuelling tumour growth. However, less is known regarding the metabolic changes that promote cancer progression to metastatic disease. Herein, we reveal that PGC-1a expression and activity are differentially regulated depending on breast cancer metastatic sites. more...

Hepatic microRNA Expression by PGC-1α and PGC-1β in the Mouse II

(Submitter supplied) The fine-tuning of liver metabolism is essential to maintain the whole-body homeostasis and to prevent the onset of diseases. The peroxisome proliferator-activated receptor-γ coactivators (PGC-1s) are transcriptional key players of liver metabolism, able to regulate mitochondrial function, gluconeogenesis and lipid metabolism. Their activity is accurately modulated by post-translational modifications. more...
