Our results imply that some putative survival skills measured in nonlethal assays reflect responsiveness to an actual predator, but they do not relate directly to their analogues in actual predator prey interactions.
Each patient's tumour was assayed for responsiveness to the 15 therapies.
Prior to assays the responsiveness of transfected Cos7 and Hek293 cells was tested by stimulating cAMP production using Forskolin (10 mM, 1 mM and 0.1 mM; Sigma-Aldrich).
To understand the metabolic consequences of such acute fat and weight accumulation, we assayed insulin responsiveness in bears during three seasons: autumn (pre-hibernation in October when the bears are most obese), winter (hibernation in January), and spring (April/May following arousal from hibernation but before mating or hyperphagia).
By assaying the responsiveness of two variants of the Tetrahymena ribozyme to the Ca2+ ion as a sign for the more catalytically useful Mg2+ ion, we show an empirical proof-of-principle that interpretation can be an evolvable trait in RNA, often suggested as a model system for early life.
Unfortunately, other functional tests to precisely assay the adaptive responsiveness of T cells (for example, response to antigens, specific cytotoxicity, and so on) are scarce.
The large differences in heat sensitivity and development of thermotolerance observed among individual tumours, irrespective of histological origin, suggested that an in vitro predictive assay for heat responsiveness would be very useful for stratification purposes in such clinical trials.
Recently, Kusama at al. amplified and cloned the putative promoter regions of 23 human ATG genes to check their responsiveness to E2F1 in a promoter-luciferase reporter assay.
To ascertain that the reference electrode was correctly placed, and to check that flies responded to external stimuli, flies were assayed for light responsiveness before every recording.
Transfected LTRs were assayed for their responsiveness to prostratin alone, to VPA alone, or to both agents in combination.
