ABCC1

A gene on 16p13.1 that encodes a protein of the MRP subfamily of the superfamily of ATP-binding cassette (ABC) transporters, which transport various molecules across extra- and intracellular membranes, many of which are involved in multidrug resistance. ABCC1 is a transporter of multispecific organic anions, glucuronides and sulfate conjugates of steroid hormones and bile salts; it mediates ATP-dependent transport of glutathione and glutathione conjugates, leukotriene C4, methotrexate, antivirals and other xenobiotics, and confers resistance to anticancer drugs.

The cDNA templates were then diluted 1:4 with nuclease-free water and amplified by polymerase chain reaction (PCR) using Taq polymerase (Takara Bio, Shiga, Japan), and specific primers based on porcine ABCC1, ABCC9, SLCO4C1, and SLCO5A1 mRNA sequences.
The levels of expression of ABCC1, ABCC9, SLCO4C1, and SLCO5A1 genes in endometrial and chorioallantoic tissues were analyzed by real-time RT-PCR using the Applied Biosystems StepOnePlus System (Applied Biosystems, Foster City, CA, USA) and SYBR Green method.
Non-radioactive in situ hybridization was performed to deter mine the localization of ABCC1 and ABCC9 expression in the uterine endometrium as previously described with some modifications [20].
Explant tissues were then collected and total RNA or protein was extracted for real-time RT-PCR and immunoblot analysis, respectively, to determine the expression levels of ABCC1, ABCC9, SLCO4C1, and SLCO5A1 mRNAs.
Data from real-time RT-PCR for ABCC1, ABCC9, SLCO4C1, and SLCO5A1 expression during the estrous cycle and pregnancy were subjected to least squares analysis of variance using the general linear models procedures of SAS (Cary, NC, USA).
On D12 and D15 post-estrus, expression of ABCC1 mRNA was affected by pregnancy status (p<0.
Expression of ABCC1, ABCC9, SLCO4C1, and SLCO5A1 mRNAs in conceptuses during early pregnancy and in chorioallantoic tissues during late pregnancy
As shown in Figure 2B, levels of ABCC1 and ABCC9, but not SLCO4C1 and SLCO5A1 mRNAs changed in chorioallantoic tissues on D30, D60, D90, and D114 of pregnancy (quadratic effect of day for ABCC1, p = 0.
The results revealed that, as compared to parental cell HeLaS3, the KB-vin MDR cell line expressed 1600 fold higher ABCBl gene, while the other two transporters, ABCC1 and ABCG2, remained equivalent levels in both cell lines (Fig.
The expression level of ABCC1 of A-549/DDP was higher than that of A-549 (Table 4).
In a long-term assay, pipeline lowered the expression level of ABCB1, ABCC1 and ABCG2 genes which encode P-gp, MRP 1 and BCRP, respectively.
