Induced pluripotent stem (iPS) cells derived from disease patients are an invaluable resource for biomedical research and may provide a source for replacement therapies. In this study, we have generated iPS cells from Asian patients with chronic degenerative diseases of the nervous system, including spinal muscular atrophy (SMA), Parkinson disease (PD) and amyotrophic lateral sclerosis (ALS) by transduction with four factors (KLF4, SOX2, OCT4 and c-MYC). All of the iPS cells showed pluripotency similar to that of human embryonic stem cells (hESCs) and were able to differentiate into various somatic cell types in vitro and in vivo. Furthermore, the iPS cells also can be committed to differentiate into neural cells, the cell type that is affected in chronic degenerative diseases. Therefore, the patient-specific iPS cells we generated offer a cellular model in which to investigate disease mechanisms, discover and test novel drugs and develop new therapies for chronic neurodegenerative diseases.

Fast excitatory neurotransmission is mediated largely by ionotropic glutamate receptors (iGluRs), tetrameric, ligand-gated ion channel proteins comprised of three subfamilies, AMPA, kainate and NMDA receptors, with each subfamily sharing a common, modular-domain architecture. For all receptor subfamilies, active channels are exclusively formed by assemblages of subunits within the same subfamily, a molecular process principally encoded by the amino-terminal domain (ATD). However, the molecular basis by which the ATD guides subfamily-specific receptor assembly is not known. Here we show that AMPA receptor GluR1- and GluR2-ATDs form tightly associated dimers and, by the analysis of crystal structures of the GluR2-ATD, propose mechanisms by which the ATD guides subfamily-specific receptor assembly.

We have developed a restriction map of the chromosome 21 breakpoint region involved in t(8;21)(q22;q22.3) acute myelogenous leukemia (AML) and have isolated a genomic junction clone containing chromosome 8 and 21 material. Using probes from these regions, rearrangements have been identified in each of nine cases of t(8;21) AML examined. In addition, we have isolated cDNA clones from a t(8;21) AML cDNA library that contain fused sequences from chromosome 8 and 21. The chromosome 8 component, referred to as ETO (for eight twenty-one), is encoded over a large genomic region, as suggested by the analysis of corresponding yeast artificial chromosomes (YACs). The DNA sequence of the chromosome 21 portion of the fusion transcript is derived from the normal AML1 gene. A striking similarity (67% identity over 387 bp, with a corresponding 69% amino acid identity) was detected between AML1 and the Drosophila segmentation gene, runt. The critical consequence of the translocation is the juxtaposition of 5' sequences of AML1 to 3' sequences of ETO, oriented telomere to centromere on the der(8) chromosome.
