title: Ca pump messenger RNA expression in pregnant rat uterus.
abstract: Rat uterus expresses transcripts for the plasma membrane Ca pump PMCA1 and for the sarcoplasmic reticulum Ca pump SERCA2. Uterus contains two mRNA isoforms for PMCA1, one encoding a cyclic nucleotide insensitive Ca pump (PMCA1a) and the other encoding a cyclic nucleotide sensitive pump (PMCA1b). The relative ratio of mRNA to 28S RNA for PMCA1a or PMCA1b and the amount of poly A+ RNA per microgram total RNA obtained from uteri of rats pregnant for 15 days and for parturient rats was similar but the ratio of SERCA2 mRNA to 28S RNA was significantly higher in the parturient rats.
