In this pathway, however, the up-regulation of wee1 tyrosine kinase (WEE1), one of the genes strictly regulated by TGFβ1, seems to indicate a sort of actual control of cell proliferation, so both apoptosis and cell cycle entry seem to be strictly controlled in the EMT process.
It is unlikely that Rac1 inhibition directly interferes with B-cell activation as Rac1 and Rac2 make critically redundant contributions to the transduction of B-cell receptor signals required for both survival and efficient cell cycle entry [ 9, 40].
In summary, activation of MYC results in cell growth, loss of differentiation and cell cycle entry in both β-cells and SBK in vivo.
Activation of MYC causes cell growth, loss of differentiation and cell cycle entry in both β-cells and suprabasal keratinocytes in vivo.
To widen the scope of the previous analyses, we checked cell cycle entry in splenocytes, which include both T- and B-lymphocytes.
Mcm-2 expression, a marker of cell cycle entry, was increased in hepatocytes in both HCV study groups.
Overexpression of PHB in LNCaP cells inhibited androgen-mediated cell cycle entry, cell growth and gene expression, both in cell culture and in tumour xenografts.
For example, two activators of cell cycle entry, CDK4 and CDK6 appear to be induced by both factors.
We noticed that the molecular network for cell cycle entry was partially re-activated by VC (Fig. 4B and 4C).
MYCN stimulates cell cycle entry but does not alleviate the requirement for ongoing mitogenic signalling to support this proliferation.
