Diverse mitochondrial abnormalities in a new cellular model of TAFFAZZIN deficiency are remediated by Cardiolipin-interacting small molecules.

J Biol Chem 2021 Jul 24:101005. Epub 2021 Jul 24.

Department of Genetic Medicine, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA. Electronic address:

Barth syndrome (BTHS) is an X-linked disorder of mitochondrial phospholipid metabolism caused by pathogenic variants in the gene TAFFAZIN (TAZ), which results in abnormal cardiolipin (CL) content in the inner mitochondrial membrane. To identify unappreciated pathways of mitochondrial dysfunction in BTHS, we utilized an unbiased proteomics strategy and identified that complex I of the mitochondrial respiratory chain and the mitochondrial quality control protease PARL are altered in a new HEK293-based TAZ-deficiency model. Follow-up studies confirmed decreased steady state levels of specific complex I subunits and an assembly factor in the absence of TAZ; this decrease is in part based on decreased transcription, and results in reduced complex I assembly and function.

Single-cell immunoblotting resolves estrogen receptor-α isoforms in breast cancer.

PLoS One 2021 27;16(7):e0254783. Epub 2021 Jul 27.

Department of Bioengineering, University of California Berkeley, Berkeley, CA, United States of America.

An array of isoforms of the nuclear estrogen receptor alpha (ER-α) protein contribute to heterogeneous response in breast cancer (BCa); yet, a single-cell analysis tool that distinguishes the full-length ER-α66 protein from the activation function-1 deficient ER-α46 isoform has not been reported. Specific detection of protein isoforms is a gap in single-cell analysis tools, as the de facto standard immunoassay requires isoform-specific antibody probes. Consequently, to scrutinize hormone response heterogeneity among BCa tumor cells, we develop a precision tool to specifically measure ER-α66, ER- α46, and eight ER-signaling proteins with single-cell resolution in the highly hetero-clonal MCF-7 BCa cell line.

The biophysical principles underpinning muco-trapping functions of antibodies.

Hum Vaccin Immunother 2021 Jul 27:1-10. Epub 2021 Jul 27.

UNC/NCSU Joint Department of Biomedical Engineering, University of North Carolina at Chapel Hill, Chapel Hill, NC, USA.

In addition to the classical immunological functions such as neutralization, antibody-dependent cellular cytotoxicity, and complement activation, IgG antibodies possess a little-recognized and under-utilized effector function at mucosal surfaces: trapping pathogens in mucus. IgG can potently immobilize pathogens that otherwise readily diffuse or actively swim through mucus by forming multiple low-affinity bonds between the array of pathogen-bound antibodies and the mucin mesh. Trapping in mucus can exclude pathogens from contacting target cells, and facilitate their rapid elimination by natural mucus clearance mechanisms. Read More
