Abstract: To investigate the contribution that ERK/mitogen-activated protein kinase signalling makes to cell cycle progression and gene expression, we have constructed cell lines to express an inducible version of activated MEK1. Using these cells, we show that activation of MEK leads to the expression of Fra-1 and Fra-2 but not c-Fos. Treatment of Ras-transformed cells with the MEK inhibitor PD098059 blocks expression of Fra-1 and Fra-2, showing that in Ras transformation ERK signalling is responsible for Fra-1 and Fra-2 expression. Activation of MEK1 i... (read more)

Topic-specific impact indicators

Popularity: This indicator reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network.
Influence: This indicator reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically).
Citation Count: This is an alternative to the "Influence" indicator, which also reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically).
Impulse: This indicator reflects the initial momentum of an article directly after its publication, based on the underlying citation network.
