“…The plasmids À954a5-CAT, À178a5-CAT, À132a5-CAT, À92a5-CAT, and À42a5-CAT that bear the chloramphenicol acetyltransferase (CAT) reporter gene fused to DNA fragments from the human a5 gene upstream regulatory sequence extending up to 5 0 positions À954, À178, À132, À92, and À42 have been previously described. 43,44 The plasmid PXGH5, which bears a secreted version of the human growth hormone (hGH), is a kind gift of David D. Moore (Department of Molecular and Cell Biology, Baylor College of Medicine, Houston, TX, USA). The double-stranded oligonucleotides bearing the DNA-binding sites for Sp1, NFI, AP-1, and PAX6 have all been described previously.…”
