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.

(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.

(Submitter supplied) The mitochondrial and nuclear genomes contribute to mitochondrial function, and when mitochondrial function is compromised, mitochondrial retrograde signaling alters nuclear gene expression. We performed gene expression profiling of engineered cells that had mitochondria containing a disease-associated mutation that causes mitochondrial dysfunction. By generating networks of transcription factors that targeted these genes, the authors revealed putative mitochondrial retrograde signaling pathways. more...

(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...
