  sub:_4 prov:value "UMR-201-10B cells have an undetectable basal alkaline phosphatase (ALP) activity that is induced after 24 h of treatment with 10(-6) M RA (4.64 +/- 0.06 mumol/h/mg of protein). The addition of 10(-8) M calcitriol resulted in a slight induction of ALP activity after 72 h (0.43 +/- 0.07 mumol/h/mg of protein). When calcitriol was added to RA, however, over the same period ALP activity was enhanced significantly compared with treatment with RA alone (RA and calcitriol, 12.29 +/- 0.86 mumol/h/mg of protein)." ;
