The obligatory intestinal folate transporter PCFT (SLC46A1) is regulated by nuclear respiratory factor 1 (NRF-1).

WOW! I think studies have demonstrated that NRF-1 is important in its regulation with PGC-1a for mitochondrial biogenesis and regulated by Nrf2. This further supports the importance of Nrf2 in environmental disease especially those that have been associated with folate deficiency! We noted another study that broccoli has a role in regulating folate which supports the need for proper Nrf2 function.


CiteULike: The obligatory intestinal folate transporter PCFT (SLC46A1) is regulated by nuclear respiratory factor 1 (NRF-1).: "identify NRF-1 as a major inducible transcriptional regulator of PCFT gene expression. The implications of this linkage between folate transport and metabolism with mitochondria biogenesis and respiration are discussed"
