Therefore, protein pyrophosphorylation, which can be effected by either form of IP7, may be the underlying molecular basis for the regulation of rDNA transcription by inositol pyrophosphates, and the target may be RNA Pol I and associated factors involved in rRNA synthesis.
Punch presses are usually driven by electric motors, and conversion from the rotary motion of the drive shaft to reciprocation of the ram is effected by either a crank, a toggle, or a cam mechanism.
Plant polyphenols are powerful antioxidants that exert their effects either by scavenging reactive oxygen and nitrogen species, or by functioning as chain-breaking peroxyl radical scavengers [ 35, 36].
Such an effect can be explained either by a neutralizing effect on toxic α-helical Aβ or, alternatively, by these inhibitors blocking earlier stages in the aggregation process that can lead to the formation of the actual toxic species.
This effect may be explained either by the rare codons effects on the early elongation region to reduce ribosome traffic jams in the rest of transcript or by their impacts on reduction of GC content at the beginning region.
Such cushion effect can be achieved either by an extremely compliant film or a 'hard' film with a large coefficient of thermal expansion.
