...Dorothea Schulte; Dirk Geerts ABSTRACT MEIS transcription factors are key regulators of embryonic development and cancer. Research on MEIS genes in the embryo and in stem cell systems has revealed novel and surprising mechanisms by which these proteins control gene expression. This Primer...

... converge at Meis genes. (A) Venn diagram representation for the overlap among proximal genes that are normally repressed by RING1B but can be activated by RA signals in the distal region of the forelimb bud. We investigated genes that are bound by RING1B in the distal region (RING1B target), derepressed...

... ( Mercader et al., 2000 ), according to which PD specification depends on the opposed action of proximal RA and distal FGF signals. However, the apparently normal Meis gene expression and PD hindlimb patterning in mice deficient for the enzyme RDH10 (part of the RA synthesis pathway) have challenged the view...

... of distal transformation. They also have nuclear MEIS, which can act as an upper arm identity regulator, only upon upper arm amputation. By contrast, myogenic cells do not obey the rule of distal transformation and display nuclear MEIS upon amputation at any proximo-distal level. These results indicate...

Transfection of Meis-inactivating constructs impaired RPC proliferation and led to microphthalmia. RNA-interference-mediated knock-down of expression indicated...

...Seong-Kyu Choe; Nikolaos Vlachakis; Charles G. Sagerström Meis homeodomain proteins function as Hox-cofactors by binding Pbx and Hox proteins to form multimeric complexes that control transcription of genes involved in development and differentiation. It is not known what role Meis proteins play...

..., and probably function by revealing the intrinsic specificity of Hox proteins.

Mann ABSTRACT homothorax ( hth ) is a Drosophila member of the Meis family of homeobox genes. hth function is required for the nuclear localization of the Hox cofactor Extradenticle (EXD).
