The phrase "activates over" is not standard in written English and may cause confusion.
It could be used in contexts where something is triggered or initiated in relation to another element, but it is not commonly used.
Example: "The system activates over a specific temperature threshold."
Alternatives: "triggers at" or "initiates upon".
One is a split-second response to a sudden increase in sunlight, say, after a cloud passes by, while the other activates over minutes to hours as light gradually changes during sunrise or sunset.
HIF-1 activates over 800 target genes that are involved in cell proliferation, angiogenesis, glycolytic energy metabolism, and apoptosis [ 5].
Indeed, under hypoxic conditions, HIF-1 α becomes stabilized and forms a heterodimeric transcription complex with HIF-1 β, which activates over 100 downstream genes important in hypoxic survival.
3 A-T is an autosomal recessive disorder, caused by mutations in the ataxia-telangiectasia mutated gene (ATM), a serine/threonine kinase that activates over a hundred proteins involved in DNA damage response, cell cycle regulation, and other pathways.
When this system is activated over and over and over again?
The ever-diligent Android Police has discovered the sensor does not work when the phone is locked, so the screen is activating over and over again when put in a pocket.
Likewise, Sox9, when activated, over-rides Runx2 function in ObL cells as shown by the phenotypes seen in transgenic mice in which Sox9 is driven by the type Iα collagen promoter [41].
Tamoxifen also has one toxic effect, activating over-expressed ERBB2, which might help explain certain side effects when using Tamoxifen.
Tamoxifen has only 1 therapeutic effect by activating under-expressed JUN, while 2 toxic effects by activating over-expressed E2F1 and inhibiting under-expressed IRS1.
Here we show that similarly to dnd2 in A. thaliana [ 10], nec1 in barley activates constitutive over-accumulation of SA.
In this new pretreatment process, palladium (II -hexafluoroacetylacetonate (Pd(hfa)2) II -hexafluoroacetylacetonateiber/fabric, and it can be easily activated by over-heating without hydrogen.
