Understanding how liver-specific sugars affect a protein linked to Niemann-Pick disease

Official title: Investigating the importance of liver-specific glycans on NPC1 proteostasis

Funded at University of Iowa · NIH-11055968 · Data updated 2026-11-12

This study is looking at how certain sugars in the liver affect a protein called NPC1, which is important for moving cholesterol and is linked to Niemann-Pick disease type C, to find ways to help improve liver health for people with this condition.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals diagnosed with Niemann-Pick disease type C, particularly those experiencing liver-related symptoms.

Less likely to help

Patients without Niemann-Pick disease type C or those whose condition does not involve liver complications may not benefit from this research.

What this research studies

This research investigates the role of liver-specific glycans in the stability and function of the NPC1 protein, which is crucial for cholesterol transport and is implicated in Niemann-Pick disease type C. The study aims to explore how these glycans influence the degradation and trafficking of the NPC1 protein, particularly in the liver, where defects can lead to severe health issues. By examining the differences in glycosylation between liver and brain NPC1, the research seeks to identify potential therapeutic targets for improving liver function in affected patients. The approach includes biochemical assays and cellular models to assess NPC1 proteostasis.

Why it matters

Potential benefit: If successful, this research could lead to new therapeutic strategies for managing liver complications in Niemann-Pick disease type C patients.

How similar studies have gone: While the specific focus on liver NPC1 proteostasis is novel, similar approaches targeting protein stability in other contexts have shown promise in previous research.
