Mice deleted for heart-type cytochrome c oxidase subunit 7a1 develop dilated cardiomyopathy.
Hüttemann M, Klewer S, Lee I, Pecinova A, Pecina P, Liu J, Lee M, Doan JW, Larson D, Slack E, Maghsoodi B, Erickson RP, Grossman LI. Hüttemann M, et al. Mitochondrion. 2012 Mar;12(2):294-304. doi: 10.1016/j.mito.2011.11.002. Epub 2011 Nov 20. Mitochondrion. 2012. PMID: 22119795 Free PMC article.
Subunit 7a of mouse cytochrome c oxidase (Cox) displays a contractile muscle-specific isoform, Cox7a1, that is the major cardiac form. To gain insight into the role of this isoform, we have produced a new knockout mouse line that lacks Cox7a1 …

Conserved function of the long noncoding RNA Blnc1 in brown adipocyte differentiation.
Mi L, Zhao XY, Li S, Yang G, Lin JD. Mi L, et al. Mol Metab. 2016 Nov 3;6(1):101-110. doi: 10.1016/j.molmet.2016.10.010. eCollection 2017 Jan. Mol Metab. 2016. PMID: 28123941 Free PMC article.
Different truncation mutants of Blnc1 were generated to identify functional RNA domains responsible for thermogenic gene induction. RNA-protein interaction studies were performed to delineate the molecular features of the Blnc1 ribonucleoprotein complex. ...A conser …

Hypoxia Inducible Factors Modulate Mitochondrial Oxygen Consumption and Transcriptional Regulation of Nuclear-Encoded Electron Transport Chain Genes.
Hwang HJ, Lynn SG, Vengellur A, Saini Y, Grier EA, Ferguson-Miller SM, LaPres JJ. Hwang HJ, et al. Biochemistry. 2015 Jun 23;54(24):3739-48. doi: 10.1021/bi5012892. Epub 2015 Jun 12. Biochemistry. 2015. PMID: 26030260 Free PMC article.
To gain a more comprehensive understanding of the role of HIF1 in mitochondrial homeostasis, we studied the link between hypoxia, HIF1 transactivation, and electron transport chain (ETC) function. We established immortalized mouse embryonic fibroblasts (MEFs) for HI …
