NormFinder ranks reference genes according to the least estimated intra- and inter-group variation, which is more effective to control the influence of co-regulation of reference genes.
Several studies have shown that using a single housekeeping gene as a reference for renal studies may reflect regulation of the reference gene rather than the target gene [ 23, 24].
In order to inhibit the DC circulating current, there are some developed methods such as voltage and current double close-loop control, three-state hysteresis control, filter circuit elimination and regulation of the reference sine wave DC component (Chen et al. 2004; He and Xu 2012; He and Zhang 2008).
The second important point that should be stressed is the possible co-regulation of selected reference genes.
For instance, a recent report indicated the de-regulation of common reference genes in hepatocellular carcinoma (HCC) arising from hepatitis C virus (HCV) infected liver [ 12].
Moreover, several recent studies report that such variation may by due to active regulation of classical reference genes under certain experimental conditions (see: http://normalisation.gene-quantification.info).info
Indeed, we observed 1.8-fold up-regulation of a reference peptide of RanGAP1 in the TK6 nuclear extract, but not in the TK6 whole cell extract (data not shown).
For product evaluation, HSA leveraged on public assessment reports and stringent regulations of its five Reference Agencies (HSA Guidance (page 42 of 166) 2016) to approve products.
"Before justifying economically damaging regulations by reference to 'the' social cost of carbon," he said, "policymakers must realize the dubious nature of this concept".
The system is composed of three main parts: computation of reference currents, regulation of DC capacitor voltage, and production of firing pulses.
Therefore, we examined the response of TA and its regulation with reference to IM application in these settings.
