Scientists Uncover Three Genes Linked to Multiple Sclerosis
New research published in the Annals of Clinical and Translational Neurology has identified three genes and their expressed proteins that may be involved in the pathogenesis of multiple sclerosis.
By comparing information on the genes and proteins expressed in the brains of thousands of individuals with and without multiple sclerosis, investigators discovered different expression levels of the SHMT1, FAM120B, and ICA1L genes (and their proteins) in brain tissues of patients versus controls.
Protein abundance alteration in human brain has linked to MS. For instance, protein abundance of glial fibrillary acidic protein (GFAP), myelin basic protein (MBP)3 and thymosin β-46 was dysregulated in lesions from MS patients’ brain, and these proteins have been used for disease severity prediction and targeted therapy lately. In addition, compared to bodily fluid samples like cerebrospinal fluid and plasma, human brain tissue directly reflects the pathophysiology changes of MS and has become increasingly important in disease biomarker identification. However, few studies focused on specific subregions of the brain, ignoring the possible differences in protein types and abundance between subregions with distinct functions.
Studying the functions of these genes may uncover new information on the mechanisms involved in the development and progression of multiple sclerosis. “Our findings shed new light on the pathogenesis of MS and prioritised promising targets for future therapy research,” the authors wrote.
