Sandhoff disease (SD) is a lysosomal disorder caused by mutations in the HEXB gene. To date, 43 mutations of HEXB have been described, including 3 large deletions. Here, we have characterized 14 unrelated SD patients and developed a Multiplex Ligation-dependent Probe Amplification (MLPA) assay to investigate the presence of large HEXB deletions. Overall, we identified 16 alleles, 9 of which wer...
Retinal abnormalities are well documented in patients with ganglioside storage diseases. The total content and distribution of retinal glycosphingolipids was studied for the first time in control mice and in Sandhoff disease (SD) and GM1 gangliosidosis mice. Light and electron microscopy of the SD and the GM1 retinas revealed storage in ganglion cells. Similar to previous findings in rat retina...
Branched chain N-acetylglucosaminyl oligosaccharides accumulating in visceral and neural tissues of two patients with Sandhoff disease were isolated and quantified using high performance liquid chromatography. Detailed structural analysis of the three most abundant fractions, oligosaccharides 4, 5, and 6, was carried out using 360 MHz proton magnetic resonance spectroscopy. The biantennary bise...
Introduction: There are many neurodegenerative diseases that cause abnormalities in the lysosome including Alzheimer’s, Tay-Sachs, and Sandhoff disease. In these diseases, cellular irregularities such as oxidative stress and excessive macromolecule accumulation disrupt the membrane integrity of the lysosome, causing the organelle to lose its acidity. We hypothesize that magnetic resonance imagi...
In some Proteobacteria and Firmicutes such as Pseudomonas aeruginosa, Vibrio cholerae, Xanthomonas campestris, and Clostridium difficile, cyclic dimeric guanosine monophosphate (c-di-GMP) is known to regulate cellular processes, including motility, biofilm formation, and virulence, as a second messenger. Cellulose production in Acetobacter xylinum, a model organism of cellulose biosynthesis, al...
