摘要

The plasma membrane Ca2+ ATPase (PMCA) is an important regulator of free intracellular calcium, with dynamic regulation in the rat mammary gland during lactation. Recent studies suggest that Ca2+ plans a role in cellular proliferation, To determine if PMCA expression is altered in tumorigenesis. Ne compared relative levels of PMCA1 mRNA. We found that the relative expression of PMCA1 mRNA is increased, by approximately 270% and 170%, in MCF-7 and MDA-MB-231 human breast cancer cell lines deprived of serum for 72 h, respectively, compared to the similarly treated MCF-10A human mammary, gland epithelial cell line. Characterization of PMCA mRNA isoforms revealed that PMCA1b and PMCA4 mRNA are expressed in MCF-7, MDA-MB-231. SK-BR-3, ZR-75-1 and BT-483 breast cancer cell lines, We also detected PMCA2 mRNA expression in all the breast cancer cell lines examined. However, PMCA, mRNA was only detected in BT-483 cells, Our results suggest that PMCA expression may be altered in breast cancer cell lined, suggesting altered Ca2+ regulation in these cell lines. Our results also indicate that breast cancer cell lines can express mRNAs for a variety PMCA isoforms. (C) 2002 Elsevier Science Inc. All rights reserved. [References: 45]
