Impactful dietary RNA delivery requires improving uptake and enhancing digestive stability. In mouse feeding regimes, we have demonstrated that a plant-based ribosomal RNA (rRNA), MIR2911, is more bioavailable than synthetic MIR2911 or canonical microRNAs (miRNAs). Here mutagenesis was used to

The unique features of purine salvage systems of pathogenic haemoflagellates render them selectively susceptible to the cytotoxic effects of purine analogues. A series of acyclic nucleoside phosphonates were evaluated for activity against pathogenic haemoflagellates in vitro. One of the phosphonylmethoxyalkylpurines
