CRISPR-mediated 3D modeling, molecular dissection and epigenetic profiling of PWS

Deletions on chromosome 15 in the bands labeled 15q11.2-q13 on the chromosome inherited from a subject’s father cause Prader-Willi syndrome (PWS). The unique nature of this causative genetic event has been known for many years, but the precise manner in which it causes the developmental abnormalities of PWS is not completely understood since the false

Therapeutic Potential of Blocking Zinc Finger Protein 274 Binding to the PWS Locus

Our goal is to understand the molecular pathways disrupted in Prader-Willi syndrome (PWS) and to develop therapeutic interventions for this disorder. Through the biological process called genomic imprinting, the chromosome 15 that is inherited from the father has a set of genes that is switched on while the same set of genes on the chromosome 15 false

The molecular mechanism of SNORD116 action and possible SNORD116 substitution strategies

The loss of two snoRNAs, SNORD115 and SNORD116, plays a central role in the development of Prader-Willi syndrome. However, the normal function of SNORD116 is still unclear, making it difficult to understand what goes wrong when SNORD116 is lost. Dr. Stamm’s group is exploring how SNORD116 influences other genes, and their preliminary studies false

Preclinical studies of a novel epigenetic therapy for Prader-Willi syndrome

Despite the significant progress in understanding the molecular basis underlying Prader-Willi syndrome, little advance has been achieved in developing the treatment specifically targeting to the molecular defect. The SNORD116 between the SNRPN and UBE3A genes is important for the major features of PWS. The host transcripts and SNORD116 in the false

Reactivation of the PWS locus via disruption of the ZNF274 silencing complex (year 2)

Through a normal biological process called genomic imprinting, the chromosome 15 that is inherited from the father has a set of genes that are switched on while the same set of genes on the chromosome 15 inherited from the mother are switched off. In Prader-Willi syndrome (PWS), there is no normal copy of the paternal chromosome 15 so patients false

Activation of silenced genes in Prader-Willi syndrome

The genetic causes of Prader-Willi syndrome (PWS) are known, including as a complex disorder involving imprinted genes that normally only function after inheritance from the father. A dozen genes contribute to the clinical problems in PWS, although what most of these genes do is poorly understood. Additionally, although numerous mouse models that false

Reactivation of the PWS locus via disruption of the ZNF274 silencing complex

Through a normal biological process called genomic imprinting, the chromosome 15 that is inherited from the father has a set of genes that are switched on while the same set of genes on the chromosome 15 inherited from the mother are switched off. In Prader-Willi syndrome (PWS), there is no normal copy of the paternal chromosome 15 so patients false

Small molecules and therapeutic potential for PWS

A publication resulting from this project was highlighted in an FPWR Research Blog post “Promising First Steps Towards Genetic Therapy for Prader-Willi Syndrome” (December 2016)

Injectable protein gene activation therapy for PWS (year 2)

This proposal will investigate the development of a gene therapy for Prader-Willi syndrome (PWS). PWS is caused by the loss of a region of human chromosome 15q11-13. Humans have two copies of chromosome 15, one the mother (maternal) and one from the father (paternal). Due to an unusual mechanism called genetic imprinting, the genes affecting PWS false

Functional Assessment of snoRNA derived microRNAs in Prader-Willi Syndrome

Prader-Willi Syndrome (PWS) is a neurodevelopmental disorder, predominantly caused by a deletion on the long arm of chromosome 15. This deletion eliminates a group of genes called HBII-85 whose function is currently unknown. Therefore, this proposal aims to investigate the underlaying molecular mechanisms behind the loss of HBII-85 and how this false
