Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

Appl.No PCT/EP2025/070967 Applicant PROQR THERAPEUTICS II B.V. Inventor KLEIN, Bart
The present invention relates to antisense oligonucleotides (AONs) that can mediate RNA editing by binding to a target RNA nucleic acid molecule in a cell and recruiting an endogenous deaminating enzyme in the cell to deaminate a target adenosine in the target RNA molecule to an inosine. The target RNA molecule is a transcript molecule from the pro-opiomelanocortin (POMC) gene encoding the β-MSH peptide. Preferably, the RNA editing changes a tyrosine to a cysteine at position 221 (Y221C) in the POMC prohormone, which results in a loss-of-function of the encoded β-MSH peptide. In turn, treatment using the AONs as disclosed will result in gain of body weight and increased BMI, thereby lowering the risk of suffering from weight loss related metabolic disorders such as cachexia.
