From: Signalling crosstalk in FGF2-mediated protection of endothelial cells from HIV-gp120

Figure 9

Diagrammatic representation of signalling pathways that may be involved in FGF2-mediated protection from gp120 As indicated by the diagram and as described by the data, it is possible that the crosstalk between the PI3K/AKT/GSK3β and ERK pathways is mediated in part by PKC. PKC signalling also is reported to occur directly with PI3K and upstream of Ras. Furthermore, direct interaction between MEK and PKC downstream of Ras is reported. Likewise, ERK2 (p42) is reported to signal to Raf-1 via a positive feedback mechanism. The points of action of the inhibitors LY290042, U0126, Bisindolymaleimide I, and Gö6983 are also shown.
