Oxidative phosphorylation promotes primary melanoma invasion

(Submitter supplied) Dermal invasion is a hallmark of malignant melanoma. The molecular alterations driving the progression of primary melanoma to metastatic disease have been studied extensively, whereas the early progression of non-invasive primary melanoma to an invasive state is not well understood. To elucidate the mechanisms underlying the transition from radial to vertical growth, the first step in melanoma invasion, we developed a zebrafish melanoma model in which constitutive activation of ribosomal protein S6 kinase 1 (RSK1) drives tumor invasion. more...

Anti-Warburg effect elicited by mitochondrial biogenesis drives differentiation of glioblastoma cells into astroglial cells

(Submitter supplied) Glioblastoma (GBM) is among the most aggressive of human cancers. Although differentiation therapy has been proposed to be potential approach to treat GBM, the mechanisms of induced differentiation remain poorly defined. Here, we established the induced differentiation model of GBM by using cAMP activators, which specifically directed GBM into astroglia. Next, transcriptomic and proteomic analyses uncovered oxidative phosphorylation and mitochondrial biogenesis were involved in induced differentiation of GBM. more...

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.

Profiling A375P melanoma cells following PGC1a suppression

(Submitter supplied) PGC1a is a transcriptional coactivator that regulates energy metabolism. PGC1a is highly expressed in a subset of melanoma tumors and cell lines. We generated gene-expression profile of control and PGC1alpha depleted A375P melanoma cells, a melanoma cell line that expresses very high levels of PGC1a to investigate the role of this gene in melanoma.

PGC1alpha depletion effect on melanoma cell line

Analysis of A375P melanoma cells depleted for PGC1alpha. PGC1alpha is a transcriptional coactivator that promotes mitochondrial biogenesis and respiration. A375P is a cell line that overexpresses PGC1alpha. Results provide insight into the role of PGC1alpha in melanoma.

MET Inhibition Elicits PGC1α Dependent Metabolic Reprogramming in Glioblastoma

(Submitter supplied) By utilizing proteomic and transcriptomic analysis coupled with untargeted polar and non-polar metabolite analysis by liquid chromatography/mass spectrometry, we identified a specific metabolic program elicited by c-MET inhibition. Interference with c-MET drives oxidative metabolism by increasing fatty acid oxidation (FAO) and glucose anaplerosis, which was orchestrated by the master-regulator, PGC1α. more...

A transcriptional regulatory network connects mitochondrial biogenesis and metabolic shift with stem cell commitment to hepatic differentiation

(Submitter supplied) Mitochondrial biogenesis and metabolism recently emerged as critical modulators of stemness properties and differentiation programmes. The increase in mitochondrial biogenesis and metabolic shift toward increased oxidative phosphorylations (OXPHOS) appear as hallmarks of stem cell differentiation processes. While several mechanisms support the involvement of mitochondrial biogenesis and function in the regulation of stem cell differentiation, the mechanisms triggering mitochondrial biogenesis in the context of cell differentiation remain elusive. more...

Control of oxidative stress by miRNA and impact on ovarian tumorigenesis

Mutant p53 controls tumor metabolism and metastasis by regulating PGC-1α

(Submitter supplied) Mutant forms of p53 protein often possess pro-tumorigenic function, conferring increased survival and migration to tumor cells via its “gain of function” activity. Whether and how a common polymorphism in TP53 at amino acid 72 (Pro72Arg, hereafter P72 and R72) impacts this gain of function has not been determined. We show that mutant p53 enhances migration and metastasis of tumors through the ability to bind and regulate PGC-1α, and that this regulation is markedly impacted by the codon 72 polymorphism. more...

Peroxisome proliferator-activated receptor gamma coactivator-1alpha isoforms selectively regulate multiple splicing events on target genes.

(Submitter supplied) Endurance and resistance exercise training induce specific and profound changes in the skeletal muscle transcriptome. PGC-1a; coactivators are not only among the genes differentially induced by distinct training methods, but also participate in the ensuing signaling cascades that allow skeletal muscle to adapt to each type of exercise. While endurance training preferentially induces PGC-1a1 expression, resistance exercise activates the expression of PGC-1a2, a3, and a4. 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...

Expression data of human melanoma cell lines treated with siRNA targeting SR-BI or with the pharmacologic inhibitor BLT-1

(Submitter supplied) Melanoma patients with high mRNA levels of the HDL receptor SR-BI (SCARB1) reveal poor survival outcome. The aim of the study was to evaluate the role of SR-BI in cancer progression. Therefore, SR-BI was targeted either by siRNA or by using the SR-BI specific lipid transfer inhibitor BLT-1. The SR-BI knockdown specifically revealed reduced protein glycosylation, STAT5 target gene expression and EMT pathway activation. more...
