Does RNA methylation play a role in my systemic sclerosis disease?
RNA methylation is a type of chemical modification that can affect how your genes are turned on or off. In systemic sclerosis (SSc), researchers are finding that these modifications may influence inflammation and fibrosis (tissue scarring), which are key features of the disease. While the science is still emerging, current evidence suggests RNA methylation is involved in SSc and could lead to new biomarkers or treatments in the future.
What the research says
A systematic review of autoimmune rheumatic diseases, including systemic sclerosis, found that RNA methylation plays a crucial role in disease progression by affecting inflammation and immune responses 1. The review highlights that RNA modifications can influence how genes are expressed, which may contribute to the development of SSc and other conditions like rheumatoid arthritis and lupus 1.
In fibrosis, a hallmark of SSc, RNA methylation has been directly studied. A 2022 review explains that the most common RNA modification, called N6-methyladenosine (m6A), is involved in fibrosis in various organs, including the skin and lungs, which are commonly affected in SSc 7. This modification is regulated by a set of enzymes that add, remove, or recognize the methylation mark, and changes in these enzymes have been linked to fibrotic diseases 7.
Another study looked at a specific gene called IRF7, which is involved in immune signaling. In patients with SSc, the IRF7 gene was found to be more active (overexpressed), and this was associated with changes in DNA methylation (a related epigenetic process) 8. While this study focused on DNA methylation rather than RNA methylation, it shows that epigenetic changes are important in SSc and that RNA methylation may be part of a larger network of gene regulation 8.
Overall, the research indicates that RNA methylation is a key player in SSc, but more studies are needed to fully understand how it works and whether it can be targeted for treatment.
What to ask your doctor
- What is the current understanding of how RNA methylation affects systemic sclerosis?
- Are there any tests for RNA methylation that might help monitor my disease?
- Could RNA methylation be a target for future treatments in SSc?
- How do epigenetic changes like RNA methylation relate to my specific symptoms or disease progression?
- Are there any clinical trials looking at RNA methylation in SSc that I might be eligible for?
