The numbers 1, 2 and 3 indicate the three locations where the BR6 strain differs from the GR and C3H strains in this region of the MMTV gene 17,18,19

Abstract

The and ↓ indicate the location at which the identical single base change described in the text occurs. The numbers 7656 and 7905 indicate the location of the MMTV 250 bp gene sequence within the MMTV genome [17]. Clones are designated as M (mother), D (daughter), and F (father) followed by a number (1–4) denoting the order in which they were cloned. - denotes the same nucleotide.<p><b>Copyright information:</b></p><p>Taken from "Mouse mammary tumor virus (MMTV)-like DNA sequences in the breast tumors of father, mother, and daughter"</p><p>http://www.infectagentscancer.com/content/3/1/2</p><p>Infectious Agents and Cancer 2008;3():2-2.</p><p>Published online 28 Feb 2008</p><p>PMCID:PMC2277433.</p><p></p
