Defects in retinal pigment epithelium cell proliferation and retinal attachment in mutant mice with p27Kip1 gene ablation

PURPOSE Little is known about the mechanisms that regulate cell cycle withdrawal of the retinal pigment epithelium (RPE) during development, or about the mechanisms maintaining epithelial cell quiescence in adult retinas. The present study examines the potential role of the negative cell cycle regulator p27(Kip1) in controlling RPE proliferation, using mice with targeted ablation of the p27(Kip...

Zebrafish dou yan mutation causes patterning defects and extensive cell death in the retina.

The size of an organ is largely determined by the number of cells it contains, which in turn is regulated by two opposing processes, cell proliferation and cell death, however, it is generally not clear how cell proliferation and cell death are coordinated during development. Here, we characterize the zebrafish dou yan(mi234) mutation that results in a dramatic reduction of retinal size and a d...

Elevated levels of the chemokine GRO-1 correlate with elevated oligodendrocyte progenitor proliferation in the jimpy mutant.

The dysmyelinating mutant jimpy (jp) arises from a point mutation in the mouse gene encoding proteolipid protein and is characterized by severe dysmyelination attributable to oligodendrocyte death. This mutant was used to investigate the regulation of oligodendrocyte progenitor proliferation in the postnatal spinal cord. At postnatal day 18, jp spinal cord contained a three- to eightfold greate...

Hematopoietic defects in rps29 mutant zebrafish depend upon p53 activation.

Disruption of ribosomal proteins is associated with hematopoietic phenotypes in cell culture and animal models. Mutations in ribosomal proteins are seen in patients with Diamond Blackfan anemia, a rare congenital disease characterized by red cell aplasia and distinctive craniofacial anomalies. A zebrafish screen uncovered decreased hematopoietic stem cells in embryos with mutations in ribosomal...
