Under the guidance of our Scientific Advisory Board through a carefully managed grants process, FPWR selects research projects based on the collaborative input of researchers and parents, choosing projects that are both scientifically meritorious and highly relevant for individuals with PWS and their families.

Derivation of live Prader-Willi syndrome neurons from induced pluripotent stem (iPS) cells

Funded Year: 2010

A better understanding of the causes of Prader-Willi syndrome (PWS) and the discovery of potential therapies has been hampered by the unavailability of live tissues. In our laboratory (Marc Lalande), we have established induced pluripotent stem cell (iPSC) technology to create models of human disease in a test tube/tissue culture dish. Skin cells...

Longitudinal study of reproductive hormones in Prader-Willi syndrome from infancy through adulthood

Funded Year: 2010

Hypogonadism (decreased production of testicular or ovarian hormones resulting in incomplete sexual development) is considered to be a cardinal feature of Prader-Willi syndrome, however, the clinical expression is variable. Most, but not all PWS males have unilateral or bilateral undescended testes. Arrested pubertal development leads to...

The relationship between serum brain-derived neurotrophic factor (BDNF) levels, BDNF haplotypes and neurocognitive performance in children with PWS

Funded Year: 2010

Prader-Willi Syndrome (PWS) is a genetic disease characterized by failure to thrive and low muscle tone during infancy, followed by food-seeking and severe obesity in childhood. Other manifestations include altered pain perception, cognitive impairment, maladaptive behaviors (obsessive compulsive, temper tantrums, skin picking, rigid thinking and...

MCH neurons in animal models of Prader-Willi syndrome

Funded Year: 2010

Prader-Willi syndrome (PWS) is a disease caused by mutations on human chromosome 15 leading to "floppy" infants initially, and obesity and sleep disorders later. Although genetic defects underlying PWS have been documented, it is still not well understood how the loss-of-function of genes results in various symptoms in PWS. It has been shown that...

Role of Kiss1 neurons in mediating ghrelin’s effect on reproduction and metabolism (year 1)

Funded Year: 2010

Prader-Willi syndrome (PWS) is a genetic disorder characterized by impairment of a myriad of physiological systems including growth, development, metabolism and reproduction. Although the physiological deficits observed in individuals with PWS come to be well-recognized, the mechanisms and/or cause for the generation of these characteristics are...

The 5-HT2CR: Mining a new experimental approach to therapeutics for Prader-Willi syndrome

Funded Year: 2010

Prader-Willi Syndrome (PWS) is a complex genetic disorder in which several genes are missing or not functional. PWS is characterized by initial loss of muscle tone and failure to thrive neonatally; children with PWS develop behavioral and cognitive problems, reproductive defects, and excessive overeating. A major medical concern is the morbid...
