How the pool of active Lck and Fyn may be maintained or upregulated in the vicinity of triggered TCRs is an open question.
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.
Hypoxia was shown to maintain or upregulate ovarian CSC characteristics [ 57].
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].
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.
mRNA was extracted from the different types of EB and it was noted that Gp130 and Stat3 (proteins involved in maintaining pluripotency) were upregulated only in the white KO population (data not shown).
In contrast, genes associated with the mesoderm (ME) lineage (MESP1, MIXL1, LHX1) were upregulated and maintained over 10 passages.
The expression levels of the sequences corresponding to the glycoprotein EDGP, FeBOx, HSP21, β-tubulin, and TRAPP beta3 were upregulated and maintained many fold higher expression level at 6, 12, and 24 hrs after AsV treatment.
To investigate this idea, we have set out to establish whether breast cancer cells maintain or upregulate PTHRP-R expression in these lesions by comparing the frequency and extent of PTHRP-R expressinn in BM with that in primary breast cancers.
