SOE: This is well before my time. The connection between the University of Oslo with LOB and ICAME is very much down to Stig Johansson. Some of this is discussed in Leech and Johansson’s article 'The coming of ICAME'(ICAME Journal No. 33, 2009).展开更多

XP patients frequently exhibit neurological degeneration, but the underlying mechanism is unknown, in part due to lack of proper disease models. Here, we generated patientspecific induced pluripotent stem cells (iPSCs) harboring mutations in five different XP genes including XPA, XPB, XPC, XPG, and XPV. These iPSCs were further differentiated to neural cells, and their susceptibility to DNA damage stress was investigated. Mutation of XPA in either neural stem cells (NSCs) or neurons resulted in severe DNA damage repair defects, and these neural cells with mutant XPA were hyper-sensitive to DNA damage-induced apoptosis. Thus, XP-mutant neural cells represent valuable tools to clari the molecular mechanisms of neurological abnormalities in the XP patients.展开更多

Mutations in a number of genes including SOD1 and FUS are associated with familial ALS. Here we report the generation of induced pluripotent stem cells (iPSCs) from fibroblasts of familial ALS patients bearing SOD1+1A27~c and FUS+/GISe6A mutations, respectively. We further gener- ated gene corrected ALS iPSCs using CRISPR/Cas9 system. Genome-wide RNA sequencing (RNA-seq) analysis of motor neurons derived from SOD1+~A272c and corrected iPSCs revealed 899 aberrant transcripts. Our work may shed light on discovery of early biomarkers and pathways dysregulated in ALS, as well as provide a basis for novel therapeutic strategies to treat ALS.展开更多

These unique properties make them increasingly attractive for novel applications in disease modeling, drug discovery, and cell therapy (Buganim et al., 2014; Liu et al., 2011; Liu et al., 2012; Sanchez Alvarado and Yamanaka, 2014). Moreover, iPSCs hold great potential for personalized cell therapy as they avoid some of the ethical concerns as well as the immunological rejection issues ascribed to ESCs.展开更多
