HTRA1 transcription in human iPSCs derived from wet AMD patients.
A, genotyping of non-insertion/deletion versus insertion/deletion versions of the human HTRA1 gene transcription regulatory region. B, detection of human iPSC marker genes by RT-PCR. Detection of GAPDH was used as an internal control. C, relative transcriptional level of HTRA1 determined by quantitative RT-PCR for iPSCs derived from individuals with non-insertion/deletion (control) versus insertion/deletion (wet AMD) transcription regulators. Sample 1, 30-year-old non-AMD male; sample 2, 72-year-old wet AMD female; sample 3, 38-year-old non-AMD male; sample 4, 71-year-old non-AMD female; sample 5, 71-year-old wet AMD female. Error bars, S.D.
