Previously we have shown that tamoxifen (TAM) induces morphological and biochemical changes typical of apoptosis in oestrogen receptor (ER)-positive MCF-7 or ER-negative MDA-231 human breast cancer cells. In this study the effects of TAM on expression of transforming growth factor beta 1 (TGF-beta 1) were correlated with the effects on cell cycle kinetics(More)
Classically known for its indispensible role in embryonic development, the Notch signalling pathway is gaining recognition for its regulation of adult tissue homoeostasis and aberrant activation in disease pathogenesis. The pathway has been implicated in cancer initiation and development, as well as early stages of cancer progression by regulating conserved(More)
To gain insight on the role of transacting factors in the regulatory mechanism of H2B histone gene expression during the differentiation of HL-60 cells by 12-O-tetradecanoylphorbol 13-acetate (TPA), the binding pattern of nuclear proteins to various elements in the human H2B histone gene upstream region have been investigated with DNase I footprinting and(More)
