Here, we report that expression of Protein A requires a threshold level of Rot.
By varying Rot expression from an inducible promoter we showed that expression of Protein A requires a threshold level of Rot.
In addition, activation of the RNAi machinery may require a threshold level of shRNAs that is reached in transiently transfected A6 cells, but not in stably transgenic tadpoles.
The concordantly lowered expression level of both opsin genes in cave populations of G. minus compared to sister surface populations is consistent with an as of yet unspecified pleiotropic function of opsin proteins, which may require a threshold level of expression.
Therefore, declining levels of E, especially estradiol (E2), may contribute to age-related bone loss in men suggesting that the male skeleton may require a threshold level of E for preventing increased bone resorption and bone loss [ 15, 18, 20, 21, 26, 30, 31].
We showed evidences that agonist-dependent, receptor-mediated cytotoxic effect requires a threshold-level expression of TRPV1.
Targeted inactivation of PTH and the Ca-sensing receptor have further delineated the existence of calcium-stimulated FGF23 production independent of other variables, and demonstrated that calcium-mediated increases in FGF23 levels required a given threshold level of serum phosphorus concentration [ 22].
The proposed method is assessed against two explicit and two implicit time integration techniques in terms of computational cost required to achieve a threshold level of accuracy.
In one investigation, the technician was required to choose a threshold level, then the image analysis program automatically extracted relevant measures from the resulting black and white image.
