The square root of COX-deficient fibre density was used in all analyses, which was identified by Box-Cox as the optimal transform.
Similarly, in the meta-analysis (n = 39), both mitochondrial DNA heteroplasmy (b = 0.49, P = 0.0012) and MT-CO gene deletion (b = 0.34, P = 0.0192) were significantly correlated with COX-deficient fibre density (R = 0.31).
We also identified that MT-CO deletion, that is involvement of either MT-CO1, MT-CO2 or MT-CO3 in the deleted region, is predictive of COX-deficient fibre density.
As the inclusion of MT-CO genes within the deleted mitochondrial DNA region was significantly correlated with a larger mitochondrial DNA deletion size in both our cohort and the meta-analysis, we also examined whether there was a correlation between mitochondrial DNA deletion size and COX-deficient fibre density.
To determine respiratory-deficient neuron density, total GM, and immediate subcortical WM identified as the WM region bordering and within 250μm from layer VI areas were calculated separately by scanning the entire sections at low magnification and measuring regions of interest using the AxioVision 4.8 program.
In our patient cohort (n = 72), we observed that both muscle mitochondrial DNA heteroplasmy (b = 0.68, P < 0.0001) and MT-CO gene deletion (b = 0.31, P = 0.0018) were significantly correlated with COX-deficient fibre density using multiple linear regression (R = 0.43) (Fig. 3).
We also applied multiple linear regression analyses to examine the relationship between these predictors and outcome measures such as age at onset, clinical phenotype and severity of the biochemical defect (as determined by COX-deficient fibre density) in both our cohort and a meta-analysis of previously published data.
Despite being α-SG deficient, the sucrose density gradient pattern of the cardiac DGC from Sgca-null mice had a similar pattern to that of wild-type mice except that ɛ-SG appeared up-regulated.
Correspon-dingly, high fat cholesterol diet (HFHC -fed mice deficient in low-density lipoprotein (LDL) receptor ligand ApoE (ApoE−/−) and rabbits on fat-enricHFHC -fed feature high LDL and oxidized LDL (oxLDL) plasmiceevels [ 19- 21] andeficient ultrastructural retinal changes similar to those observed in human AMD [ 22], inclipoproteinhickening and BM LDLid deposits [ 23- 25].
We show herein that the combination called lipistase meets this expectation and reduces body weight gain, plasma lipids, hepatic steatosis, and atherosclerosis in mice deficient in low-density lipoprotein receptor (LDLrKO) or in apolipoprotein E (APOEKO), two common models for investigating adiposity or atherosclerosis, respectively.
