However, a small number of proteins such as PlGF (PGF) or VEGFA were reduced on Chemo-placebo whereas they were maintained or upregulated in patients treated with Chemo-cediranib.
Can it be maintained or even improved?
In 13 out of 15 patients, prostein transcripts were found at higher or similar levels in the tumour samples when compared with the corresponding nonmalignant tissues, demonstrating that prostein expression is maintained or even upregulated in the great majority of tumourous tissues.
Studies have shown that several A- and B-class Ephs are upregulated following SCI in rats, while ephrins are maintained or reduced.
OTUB1, Chk1, c-Abl and p53 maintained or upregulated the expression levels initially after transfection by 520d-5p, followed by ATR, BRCA1, CD105, SIRT1 and hTERT upregulation.
The major response was achieved at t0, and most genes (946) were maintained upregulated during early infection, whereas only 28 of the downregulated genes were common to the three studied time points.
Hypoxia was shown to maintain or upregulate ovarian CSC characteristics [ 57].
In EPI−/− epidermis treated with acetone, transcripts related to innate immunity (in particular RAGE, S100A8, S100A9 and IL-1β) were higher than in WT, and these differences were maintained when transcript levels were upregulated by TPA treatment.
Therefore, maintaining or upregulating CRP2 expression during vascular injury might serve as a protective mechanism against intimal thickening.
Likewise, Th2 cells maintain or upregulate the expression of Bcl2 via IL-4 signaling [ 36, 37] and reduce Fas and FAS-L expression [ 38– 40].
