ID’d microRNAs may serve as Rett disease progression biomarkers

A research team has identified Rett syndrome-specific molecules that regulate gene activity, called microRNAs, that are associated with the growth of patient-derived brain cells and may serve as biomarkers for monitoring Rett progression. Using 3D organoids that mimic the brain, the team identified these microRNA fingerprints within extracellular vesicles…

Rett patients see disease progression despite therapy: Study

Women and girls with Rett syndrome experience disease progression and increasing disease burden even as they rely on supportive therapies, a study found. Close to half of all patients in the study needed a hospital or emergency room visit, the researchers said. Children and adolescents saw “increasing disease severity…

Disease Severity Tied to Two Neuroprostanes

Elevated levels of two neuroprostanes — markers of oxidative stress, a result of insufficient antioxidant defenses against toxic free radicals — are linked with symptom severity and type of mutations in people with Rett syndrome, a study reports. These findings support the potential of the neuroprostanes as biomarkers to…
