2023 Week 50

Dec- 11 Mo - International Mountain Day

Mountain slopes can be difficult, but O₂ slopes can be smooth with DatLab

The default setting of Slope smoothing is 40 data points, corresponding to an interval of 80 s at a data recording interval of 2 s. DatLab 7 expresses it in data points and DatLab 8 in seconds.

Why add azide after ascorbate and TMPD when measuring Complex IV activity?

The O₂ flux measured after the titration of ascorbate and TMPD is due to both CIV activity and autooxidation of these compounds. By subsequently inhibiting CIV activity with azide, the O₂ flux due to autooxidation (chemical background) can be determined and subtracted from the initial measurement.

"SIRT4 [Sirtuin 4] knockdown increases mitochondrial capacity to oxidize fatty acids, decreasing LEAK respiration and further increasing mitochondrial elongation via its regulation of mitochondrial fusion."

Noone J, Rochfort KD, O'Sullivan F, O'Gorman DJ (2023) SIRT4 is a regulator of human skeletal muscle fatty acid metabolism influencing inner and outer mitochondrial membrane-mediated fusion. »Bioblast link«
