ABCB1 was mainly expressed by cells in the [CD45.sup.+] subpopulation while ABCC1
was expressed in both subpopulations .
Only ADAM17 and ABCC1
were significantly differentially expressed in NR or ONR without stratifying them into CTC+/-.
Although it has been shown that expression of ABCC1
gene is induced by estrogen and progesterone in human trophoblast cells , regulatory mechanisms of the expression of PG transporter genes, ABCC1
, ABCC9, SLCO4C1, and SLCO5A1 are not well understood.

)," The Journal of Biological Chemistry, vol.
and ABCG2 mRNA expression levels were quantified by real-time RT-PCR as described previously (Teng et al.
Specifically, the genetic polymorphisms of ABCB1, ABCC1
, and ABCG2 in both normal and pancreatic cancerous specimens were analyzed.

is involved in the release of sphingosine 1-phosphate from rat uterine leiomyoma ELT3 cells and late pregnant rat myometrium," Cellular Signalling, vol.
And in the recent study the researchers identified common variants at the beginning and end of the ABC1 and ABCC1
It was located on ABCC1
, the efflux carrier gene, which codes for a protein serving as a pump that removes MTX from the cell.
These downstream genes encode (1) antioxidant enzymes such as [gamma]-glutamate cysteine ligase catalytic subunit (GCLC) and regulatory subunit (GCLM), (2) phase II drug-metabolizing enzymes such as heme oxygenase 1 (HMOX1) and NAD(P)H quinone oxidoreductase 1 (NQO1), and (3) multidrug-resistant proteins (MRPs) such as ATP-binding cassette subfamily (ABC) C1 (ABCC1
), ABCC2, ABCC3, and ABCG2 [18-20].
Furthermore, Saeed and colleagues further documented an association between high ABCC1
expression and resistance to the two glycosides could not be established in the NCI cell line, and they concluded that ABC transporter had a limited role in the unresponsiveness of NCI cell line to acovenoside A and ouabain .
