Alagille Syndrome News and Research

RSS

Alagille Syndrome is a rare inherited liver disorder seen in infants and young children. The disease is characterized by a buildup of bile in the liver due to a deficiency or absence of normal bile ducts inside the liver and a narrowing of bile ducts outside the liver. Symptoms of the disorder can include jaundice, stunted growth, fatty deposits in the skin, facial deformities, and abnormalities in the heart, eyes, vertebrae, and kidneys.

Incurable liver disease could be reversed with a single drug

Research led by Associate Professor Duc Dong, Ph.D., has shown for the first time that the effects of Alagille syndrome, an incurable genetic disorder that affects the liver, could be reversed with a single drug.

New source of stem cells could help treat people with Alagille syndrome

Researchers from Sanford Burnham Prebys have discovered a new source of stem cells just outside the liver that could help treat people living with Alagille syndrome, a rare, incurable genetic disorder in which the bile ducts of the liver are absent, leading to severe liver damage and death.

Deletion of an embryonic gene in liver cells completely wipes out bile ducts of newborn mice

Scientists from the University of Pittsburgh School of Medicine described a new phenomenon in which the deletion of a single gene involved in liver embryogenesis completely wipes out bile ducts of newborn mice.

Scientists discover mechanism behind unusual form of tissue regeneration in the liver

By studying a rare liver disease called Alagille syndrome, scientists from Cincinnati Children's and the University of California San Francisco (UCSF) have discovered the mechanism behind an unusual form of tissue regeneration that may someday reduce the need for expensive and difficult-to-obtain organ transplants.

Liver disease in children with Alagille Syndrome caused by malformations of bile ducts

Serious liver and heart problems can affect children with Alagille Syndrome early in life. While there is as yet no cure, researchers at Karolinska Institutet in Sweden have discovered that the liver disease part of the syndrome is caused by specific malformations of the bile ducts.

Jaw malformations in zebrafish could provide clues about hearing loss in mice and humans

Can a fish with a malformed jaw tell us something about hearing loss in mice and humans? The answer is yes, according to a new publication in Scientific Reports.

UConn-led researchers identify specific gene linked to Hajdu-Cheney syndrome

Fragile bones are usually an old person's affliction, but sometimes children are born with them. Now, a team of researchers led by UConn professor Ernesto Canalis has shown in mice that a specific gene can cause the disease, called Hajdu-Cheney syndrome. Overabundant bone-absorbing cells may be causing the disorder's characteristic bone loss, and the researchers hope to find a potential treatment.

Phase 2 IMAGO trial of SHP625 fails to meet primary endpoints in pediatric patients with ALGS

Shire plc today announced that the 13-week Phase 2 IMAGO trial of its investigational compound SHP625 (LUM001) did not meet the primary or secondary endpoints in the study of 20 pediatric patients with Alagille syndrome (ALGS), a rare, life-threatening genetic disorder that presents with chronic cholestasis (accumulation of bile acids in the liver) and severe pruritus (itching).

Lumena Pharmaceuticals initiates LUM001 clinical program in children with ALGS

Lumena Pharmaceuticals, a company developing oral therapeutics for rare liver diseases, today announced the initiation of a global clinical program to evaluate its drug candidate LUM001 in children with Alagille syndrome. The first patient has been dosed in the IMAGO Phase II study being conducted in the U.K., and enrollment of pediatric patients is expected to begin later this year in the ITCH Phase II study in the U.S.

Embryonic signalling pathways suggest a new therapeutic approach to recover from heart attack

Almost a century after it was discovered in fruit flies with notches in their wings, the Notch signalling pathway may come to play an important role in the recovery from heart attacks. In a study published today in Circulation Research, scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, are the first to prove that this signalling pathway targets heart muscle cells and thus reveal its crucial role in heart development and repair
