These observations hint at a potential linkage between obesity and augmented NNMT activity, given MNAMs production during NNMT enzymatic reactions

Conflict of interest The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest

Some studies have used endogenous small interfering RNAs (miRNAs) to inhibit NNMT and competitive endogenous RNAs (ceRNAs) as sponges of miRNAs to reduce the inhibitory effect of miRNAs on target genes

That enzyme name sounds technical, but its role in fat metabolism is surprisingly straightforward once you understand it

Oral administration, if viable (which for most peptides, it's not due to gastric degradation), would likely lead to an even shorter effective half-life due to first-pass metabolism
