The LIM-only protein FHL2 (four-and-a-half LIM-domain protein 2) belongs to the FHL protein family of transcriptional cofactors present in various cell lines. FHL2 interacts with a variety of transcription factors known to be involved in tumour development. Furthermore, FHL2 expression is often deregulated in cancer including overexpression and(More)
The Polo-like kinase 1 (Plk1) is a key regulator of mitosis. It is reported that the human peptidyl-prolyl cis/trans-isomerase Pin1 binds to Plk1 from mitotic cell extracts in vitro. Here we demonstrate that Ser-65 in Pin1 is the major site for Plk1-specific phosphorylation, and the polo-box domain of Plk1 is required for this phosphorylation.(More)
FHL2 is a LIM-domain protein expressed in myoblasts but down-regulated in malignant rhabdomyosarcoma cells, suggesting an important role of FHL2 in muscle development. To investigate the importance of FHL2 during myoblast differentiation, we performed a yeast two-hybrid screen using a cDNA library derived from myoblasts induced for differentiation. We(More)
Deregulated cell cycle control is a hallmark of cancer cells. Developmental or other mitogenic stimuli activate the proliferation of normal cells in response to the requirements of growing tissues. In contrast, cancer cells liberate from proliferative restrictions exerted by anti-proliferative signals arising from the stroma and by endogenous genetic(More)
The transcriptional cofactor FHL2 interacts with a broad variety of transcription factors and its expression is often deregulated in various types of cancer. Here we analyzed for the first time the molecular function of FHL2 in breast cancer. FHL2 is overexpressed in almost all human mammary carcinoma samples tested but not in normal breast tissues and only(More)
We have described the scaffolding protein FHL2 as a component of focal adhesion structures, to which it is recruited via binding to both alpha- or beta-integrin subunits. Using mesenchymal stem cells from wild-type and FHL2-knockout mice, we show here that inactivation of FHL2 leads to impaired assembly of extracellular matrix proteins on the cell surface(More)
We describe an implementation of a general standard basis algorithm, valid for any monomial ordering compatible with the natural semigroup structure. We concentrate on new strategies which have proved useful, in particular in the non-wellordering case. Moreover, we describe the first implementation of Schreyer's method to compute syzygies and compare it(More)
