MIC26 and MIC27 cooperate to regulate cardiolipin levels and the landscape of OXPHOS complexesApolipoproteins of MICOS, MIC26 and MIC27, cooperatively manage cristae structure, cardiolipin levels, and the global stability and integrity of respiratory chain supercomplexes and F1Fo–ATP synthase.
Mitochondrial spongiotic brain disease: astrocytic stress and harmful rapamycin and ketosis effectAstrocyte-specific mtDNA depletion causes spongiotic encephalopathy, aggravated by ketogenic diet or rapamycin. Astrocytes, but not neurons, drive mitochondrial integrated stress response in the CNS.
BH4 activates CaMKK2 and rescues the cardiomyopathic phenotype in rodent models of diabetesThis study reports that BH4 activates CaMKK2/PGC-1α; signaling pathway and has a therapeutic effect on diabetic cardiomyopathy.
Quantification of cristae architecture reveals time-dependent characteristics of individual mitochondriaA novel, machine-learning approach to quantify cristae density and architecture in live-cell super-resolution imaging characterizes the ultrastructural parameters of individual mitochondria over time.
Snail augments fatty acid oxidation by suppression of mitochondrial ACC2 during cancer progressionThis study reports a mechanism of mitochondrial ATP generation whereby EMT-inducer Snail controls ACC2 abundance and subsequent fatty acid oxidation to support cancer survival under starvation conditions.
Importance of γ-secretase in the regulation of liver X receptor and cellular lipid metabolismInhibition of the Alzheimer associated γ-secretase impairs the regulation of cellular lipid droplet homeostasis.
Immunoglobulin expression in the endoplasmic reticulum shapes the metabolic fitness of B lymphocytesImmunoglobulins shape mitochondrial function by driving ER expansion, this form of metabolic control is independent of the role the immunoglobulins play as part of the antigen receptor on the cell surface.
Essential role of the Crk family-dosage in DiGeorge-like anomaly and metabolic homeostasisThis study presents evidence that CRK/CRKL and TBX1 may share pathways that participate in organogenesis affected in DiGeorge syndrome (22q11.2DS) via global control of gene expression and metabolism
Metabolic reprogramming of fibro/adipogenic progenitors facilitates muscle regenerationHigh-fat diet ameliorates muscle dystrophic phenotype by promoting the FAP-dependent myogenesis of satellite cells.
Refining the adipose progenitor cell landscape in healthy and obese visceral adipose tissue using single-cell gene expression profilingThis work dissects adipose progenitor cell (APC) heterogeneity in normal and obese adipose tissue using single-cell expression profiling. Novel APC subpopulations are identified and characterized.
