Kr├╝ppel-like factors are transcriptional regulators that influence several cellular functions, including proliferation. Recent studies have shown that one family member, KLF4, can function both as a tumour suppressor and an oncogene. The ability of KLF4 to affect the levels of expression of the cell-cycle regulator p21 seems to be involved, in that this protein might function as a switch that determines the outcome of KLF4 signalling. Is this role of p21 restricted to KLF4, or does p21 represent a nodal point for signals from multiple other factors with opposing functions in cancer?
