Ulefnersen sodium
Based on 1 publication(s) in Google Scholar
Ulefnersen sodium (ION363) is an Antisense Oligonucleotide (ASO) directed against the 6th intron of the fused-in sarcoma (FUS) transcript to silence FUS in a non-allele-specific manner. Ulefnersen sodium can reduce postnatal levels of FUS protein in the brain and spinal cord in disease-relevant mouse model of ALS-FUS , delaying motor neuron degeneration. Ulefnersen sodium can be used in the research of Amyotrophic Lateral Sclerosis (ALS) .

Animal Model:Newborn (postnatal day 1 (P1)) P517/WT mice [1]
-
Dosage:20 μg
-
Administration:Intracerebroventricular injection, Once in total
-
Result:Showed an overall decrease in both wild-type and mutant FUS protein to approximately 20–50% of the levels observed in matched controls at 1 month of age, as determined by western immunoblot analysis of brain and spinal cord. Decreased the levels of TDP-43, hnRNP A1, hnRNP U and UPF1 in the detergent-insoluble fractions. Showed strong nuclear signals in all cells, including MNs at 1 and 4 months. However, signals for both Ulefnersen and NTC ASO dropped to near background levels by 6 months, as determined by analysis of anti-ASO immunostaining.

Animal Model:Newborn (P1) MN-P517L/Δ14 mice[1]
-
Dosage:20 μg
-
Administration:Intracerebroventricular injection, Once in total
-
Result:Observed no MN loss and prevented muscle denervation and microgliosis at 4 months. Observed an increase in muscle denervation and microgliosis at 6 months, indicating that the onset of disease pathology was delayed rather than completely prevented. However, observed no MN degeneration at 6 months.
