title: Genetic analysis of nonhistone chromosomal protein inheritance in recombinant inbred mouse strains using two-dimensional electrophoresis.
abstract: Analysis of hepatic nonhistone chromosomal protein (NHCP) expression in male mice from progenitor strains (C3H/HeN, C57BL/6N), their F1 hybrid (B6C3), and seven recombinant inbred strains (RIs) (B6N x C3N) by high-resolution two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) detected 16 NHCPs whose expression in RIs could be correlated to each other and with strain distribution patterns (SDP) of 20 genetic markers differing in the progenitors. Of the 400+ NHCP spots detected in RI 2D-PAGE maps, 172 were common to progenitors and all RIs. There was a characteristic absence of five NHCPs in one RI, Y. Ten C3H-specific and six C57-specific NHCP inherited in B6C3 also appeared in RIs. The SDP of C3H-specific NHCP 2 matched the SDP of beta-glucuronidase on chromosome 5 and carbonic anhydrase on chromosome 3, and C57-specific NHCP 5 SDP corresponded to that for nonagouti trait on chromosome 2. These 16 NHCP genetic marker inheritance differences detected in RIs add to the 23 previously established genetic marker differences between the progenitors.
