Inflexibility of AMPK-mediated metabolic reprogramming in mitochondrial disease
Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome is most commonly caused by the A3243G mutation of mitochondrial DNA. The capacity to utilize fatty acid or glucose as a fuel source and how such dynamic switches of metabolic fuel preferences and transcriptional modulation of adaptive mechanism in response to energy deficiency in MELAS syndrome have not ...
متن کاملMetabolic Inflexibility: When Mitochondrial Indecision Leads to Metabolic Gridlock
Normal energy metabolism is characterized by periodic shifts in glucose and fat oxidation, as the mitochondrial machinery responsible for carbon combustion switches freely between alternative fuels according to physiological and nutritional circumstances. These transitions in fuel choice are orchestrated by an intricate network of metabolic and cell signaling events that enable exquisite crosst...
متن کاملFLCN: A new regulator of AMPK-dependent Warburg metabolic reprogramming
Tumor cells manage their energy to support aberrant proliferation by reprogramming their cellular metabolism, for example through the Warburg effect. Although AMPK is a major regulator of energy homeostasis, its role in cancer metabolic adaptation is unclear. We recently identified the tumor suppressor folliculin as a new regulator of AMPK-dependent metabolic transformation.
متن کاملI-10: Transcriptomics in Oocyte Mediated Cellular Reprogramming
a:4:{s:10:"Background";s:1707:"Early embryonic development in mammals begins in transcriptional silence with an oocyte-mediated transcriptional reprogramming of parental gametes occurs during a so called across-the-board process of “erase-and-rebuild”. In this process, the parental transcription programs are erased long before (maternal) or soon thereafter (paternal) fertilization to generate a...
متن کاملMetabolic testing in mitochondrial disease.
Mitochondrial oxidative phosphorylation (OXPHOS) disorders are a heterogeneous group of diseases with variable expression that often pose diagnostic dilemmas. Although definitive diagnosis of these disorders usually requires a muscle biopsy and mtDNA and enzymatic testing, standard metabolic studies including organic acid and amino acid analysis often provide useful findings that support an OXP...
