MicroRNA (miRNA) profiling studies in human AMs found that the most strongly downregulated miRNA in smokers compared with non-smokers was miR-452,37 which has a role in inhibiting the expression of MMP-12, a proteinase which degrades elastin and causes emphysema.65 The same study found that global miRNA expression was 50%60% less in AMs from smokers.37 This may be explained by the reduced expression of the cytosolic RNA endonuclease (DICER),66 that has a key role in cleaving precursor miRNAs into mature functional 2022-nucleotide miRNAs
As I mentioned above, there was a massive protrusion on the wrapper of one of the cigars, and while it did not really affect the flavor or construction in any significant way that I could discern, it was extremely obvious when I first inspected the cigar
