Its half-life is longer than insulin (20 30 vs. 3 5 min) and it therefore circulates at concentrations approximately five times higher in the systemic circulation [ 5, 6].
Measurements of free serum hormone detect hormones that are not bound to proteins in the blood and therefore circulate freely through the body.
Therefore, circulating level of galectin-4 might be a predictor for cancer patients, especially those with metastasis.
Therefore circulating memory B cells remain at very low frequencies even during a secondary infection.
Therefore, circulating resistin, as a model of protein QTL, merits further investigation, and SNPs in the vicinity of RETN would be of special interest.
Therefore, circulating miR-200c was conjectured to be the origin of metastatic site.
Therefore, circulating prorenin levels are 5- to 10-fold higher than those of renin [ 14].
Therefore, circulating miRNAs are thought to be possible diagnostic or prognostic biomarkers of human diseases.
Therefore, circulating soluble forms of CK-18 are being used to quantify apoptotic activity.
Therefore, circulating MMP-9 activity in the blood could reflect disease progression in this animal model [ 48].
