Only to a limited extent are they like regulatory user fees, based on the Government's power to regulate particular businesses or activities.
ABI1 is induced by abscisic acid and was shown to regulate stomatal aperture in leaves and mitotic activity in root meristems [ 33, 34].
Estrogenic steroids regulate cellular function in a wide variety of tissues [ 1 ] . During human pregnancy, the production of 17-beta-estradiol (E2) rises eighty fold, from 0.75 nM preovulatory peak to 60 nM at term [ 2 3 4 5 ] , and estrogens influence various aspects of placental function and fetal development in humans and primates [ 6 7 8 9 10 11 12 ] . Several previous studies have shown that human placenta binds estradiol [ 13 14 15 ] . However, more recent immunohistochemical studies on paraffin-embedded or snap frozen sections as well as other techniques (RT-PCR for ER-alpha mRNA) failed to demonstrate estrogen receptor alpha (ERα) in human placentae during pregnancy or in cultures of dispersed placental cells [ 16 17 ] . However, it has been indicated that the failure to detect the ERα does not entirely preclude the presence of this receptor in human trophoblast cells, but might be attributed to a relatively low number and density of ERα molecules on these cells [ 17 ] . On the other hand, Billiar et al.
CFTR regulation of ENaC has been described in the colon in humans [ 37 ] and in cftr knockout mice [ 37 ] . Co-localization of CFTR and ENaC suggests that direct protein-protein interactions allow CFTR to closely regulate the activity of this channel [ 39 40 ] . Our results suggest that knockout of CFTR leads to an analogous increase in expression and function of IBAT.
However, CD28-deficient T cells from proteoglycan-immunized animals can proliferate in response to proteoglycan stimulation in vitro , albeit at a rate lower than that in wild-type T cells, which is consistent with the report by Oliveira-dos-Santos et al . [ 30 ] . It has been demonstrated that, in the absence of CD28 engagement, T cells require very high TCR occupancy and prolonged stimulation, whereas CD28 costimulation allows T cells to respond to lower degrees of TCR occupancy [ 30 31 ] . In support of this observation, CD28 -/-mice can still mount immune responses, which vary in magnitude and efficiency depending on the antigen or infectious agent [ 30 32 ] . Our results and those reported by others [ 30 ] suggest that CD28 may regulate the threshold for T-cell activation.
