Northern analysis of transgene expression in mouse tissues. (A) The ~1.1kb BRCA1t340 mRNA is detected in mammary gland, salivary gland, and lung of 13-week-old virgin homozygous MMTV-BRCA1t340 (lines 1 and 2) transgenic mice. Transgene expression in kidney was not observed. (B) In addition to the mammary gland, the ~5.6kb BRCA1 or BRCA1sv mRNA is present in the salivary gland and lung of 13-week-old virgin homozygous MMTV-BRCA1 (lines 5 and 6) and MMTV-BRCA1sv (lines 90 and 61) transgenic animals. Transgene expression in kidney was not observed (data not shown).
