Folic Acid 36-42 FOS like 1, AP-1 transcription factor subunit Homo sapiens 67-75 12187485-8 2002 The presence of FR alpha in the basal membrane was demonstrable by folate binding and that of RFT-1 in the apical membrane by blockade of folate transport by RFT-1-specific antibody. Folic Acid 67-73 FOS like 1, AP-1 transcription factor subunit Homo sapiens 16-24 12187485-8 2002 The presence of FR alpha in the basal membrane was demonstrable by folate binding and that of RFT-1 in the apical membrane by blockade of folate transport by RFT-1-specific antibody. Folic Acid 138-144 FOS like 1, AP-1 transcription factor subunit Homo sapiens 16-24 12187485-9 2002 This study represents the first in vitro demonstration of transcellular transfer of folate across RPE and suggests that folate is transported from the choriocapillaris to the adjacent photoreceptor cells in vivo by the concerted action of FR alpha in the basal membrane and RFT-1 in the apical membrane. Folic Acid 120-126 FOS like 1, AP-1 transcription factor subunit Homo sapiens 239-247
