The phrase "activated by elevated" is correct and usable in written English.
It can be used in contexts where something is triggered or initiated due to an increase in a certain factor, such as temperature, pressure, or another variable.
Example: "The sensor is activated by elevated levels of carbon dioxide in the atmosphere."
Alternatives: "triggered by increased" or "initiated by heightened".
We tested the activation of these channels relative to depolarizing currents activated by elevated extracellular potassium as a calibration standard.
Studies with cells from patients with Scott disease, in which Ca2+ activation of the scramblase has been inactivated by mutation, suggest that the scramblase activated during apoptosis may be the same as the scramblase activated by elevated cytoplasmic Ca2+, but that the activation mechanisms are distinct [22].
Like calpain, AMP-activated protein kinase (AMPK), a serine/threonine kinase, is also activated by elevated calcium levels.
Protein kinase A, activated by elevated intracellular cAMP levels, phosphorylates downstream substrates and mediates the induction of genes required for aggregation and post-aggregation development.
In the absence of augmented IGF1R expression, IGF-signaling pathways could potentially still be activated by elevated expression of other components of the IGF1-signaling pathway.
Also, AtMTP1 and BjMTP1 transcription is not regulated by Zn, while AtMTP3 is activated by elevated Zn influx [ 41, 43, 47].
In this critical situation, there is a need for a mechanism that can be activated by the elevated [Ca2+]i and depolarization, and suppresses harmful, energy-consuming discharge activity, Ca2+ influx, and transmitter release.
Though BK channels are activated by both elevated cytosolic Ca2+ and membrane depolarization, they can open even in the absence of calcium [2].
Certain examples have demonstrated that AMPK is activated by an elevated AMP/ATP ratio due to cellular and environmental stress such as nutritional deprivation.
AMPK, an evolutionarily conserved enzyme that plays a pivotal role in maintaining cellular energy homeostasis [197], is activated by an elevated ratio of AMP/ATP under various stress conditions, such as hypoxia, glucose deprivation, and oxidative stress.
Catalytic activities of nickel silicates for ethylene dimerization and butene isomerization run parallel when the catalysts are activated by evacuation at elevated temperatures, giving two maxima in activities.
