More than 60 gangliosides are known, which differ from each other mainly in the position and number of NANA residues. It is a component of the cell plasma membrane that modulates cell signal transduction events, and appears to concentrate in lipid rafts [2] [3]. Recently, gangliosides have been found to be highly important molecules in ...

The GM1 gangliosidoses, usually shortened to GM1, are gangliosidoses caused by mutation in the GLB1 gene resulting in a deficiency of beta-galactosidase.The deficiency causes abnormal storage of acidic lipid materials in cells of the central and peripheral nervous systems, but particularly in the nerve cells, resulting in progressive neurodegeneration.
Beta-hexosaminidase is a vital hydrolytic enzyme, found in the lysosomes, that breaks down lipids. When beta-hexosaminidase is no longer functioning properly, the lipids accumulate in the nervous tissue of the brain and cause problems. Gangliosides are made and biodegraded rapidly in early life as the brain develops.
Researchers from Johns Hopkins University School of Medicine in Baltimore, MD, showed that total body bone mass and density both decreased in adults over the age of 65 who received levothyroxine ...
The secreted toxin attaches to the surface of the host mucosa cell by binding to GM1 gangliosides. GM1 consists of a sialic acid-containing oligosaccharide covalently attached to a ceramide lipid. The A1 subunit of this toxin will gain entry to intestinal epithelial cells with the assistance of the B subunit via the GM1 ganglioside receptor.
Loss of bone minerals means a decline in bone mass, thus bones will be weaker in some areas resulting in individuals to be at risk of minor or major falls that could be detrimental. It is known that exercise can allow for stronger bones in order to slow down bone loss in individuals as muscle mass can be built to support and reduce the risks of ...
Bone metastasis, or osseous metastatic disease, is a category of cancer metastases that result from primary tumor invasions into bones. Bone-originating primary tumors such as osteosarcoma, chondrosarcoma, and Ewing sarcoma are rare; the most common bone tumor is a metastasis. [1] Bone metastases can be classified as osteolytic, osteoblastic ...
