ACE2 in enterocytes), SLC7A9 (which codes for an L-DOPA influx transporter) and SLC16A10 (which codes for an L-DOPA efflux transporter). In the entire set of data (n = six, two handle samples, two samples at 24 h post-infection and two samples at 60 h post infection), we could extract expression values for 11 out of 14 genes of interest. We then utilized the Pearson’s correlation test to evaluate the co-expression hyperlinks between these genes and ACE2. We found that eight key genes involved in the metabolism of dopamine and/or trace amines exhibited statistically considerable co-expression hyperlinks with ACE2 across all experimental conditions. Of note, the most robust correlation link was observed for MAOB, followed by SLC7A9 and SULT1A1 (Table three).Int. J. Mol. Sci. 2021, 22,tern. Furthermore anticipated, the L-DOPA efflux transporters SLC3A2 and SLC7A8 were detected in the basolateral membrane of enterocytes. A low and diffuse staining pattern was observed for SLC16A10. Ultimately, no TH staining might be detected (Figure S1), in accordance with genomics analyses. Depending on these mined data, a scheme summarizing the ALK1 Purity & Documentation predicted dopamine/trace amines metabolic pathways taking spot in human enterocytes six of 16 is shown in Figure two.Figure two.
