Frank Mercurio and Anjana Rao report the cloning of the IκB kinases IKK - 1 and IKK - 2, the essential
upstream regulators of the transcription factor NFκB.
Researchers also found that levels of cAMP and pCREB, possible
upstream regulators of some circadian genes, were correlated with locomotor activity.
The results also established a hierarchy within the key pluripotency factors such that Klf4 serves as
an upstream regulator of feed - forward circuits involving Oct4, Sox2, Nanog and Myc.

Since the three main Westminster political parties all endorse the conclusions
of Sir Ian Wood's recent review on how to maximise the economic recovery
of oil and gas from the UK Continental Shelf (Search for UKCS Maximising Recovery Review Final Report, here), and its tacit underlying fiscal premises (namely that there is a need for a simplified fiscal regime to incentivise investment and drilling activity, as well as to ease the burden upon the new
regulator of the
upstream sector), it does not take the gift
of prophecy to appreciate that the ultimate outcome
of this subsequent review on the shape
of the UK fiscal regime seems foreordained; namely, a return to the situation that prevailed before the introduction
of SC, whereby the only levy on income from oil and gas fields is to be Corporation Income Tax at the standard rate levied on the likes
of Starbucks and Amazon.
«A beautiful aspect
of our findings is that we don't need an
upstream regulator for AP2 - G.
The sequences
of these enhancers were enriched for many
of the same transcription factor (TF) binding motifs; the authors could propose
upstream regulators for about half
of the enhancer modules they observed.
Inactivating mutations in either p53 or in some
of its
upstream regulators, notably ATM and p19ARF, are common in human cancers.
We conclude that p21 plays a significant role in tumor suppression, which is more important than that
of Bax but weaker than that
of p53 or its
upstream regulators ATM and p19ARF.
Western blot analysis showed that phosphoinositide - dependent protein kinase 1, the
upstream kinase that phosphorylates Akt, and several phosphatases (phosphatase and tensin homolog deleted on chromosome 10, protein phosphatase 1, and protein phosphatase 2A), known as negative
regulators of the PI3K / Akt signaling pathway, were unchanged upon VPA treatment (Supplemental Fig. 4E), indicating that VPA might act on Akt directly.
