Cultured cells derived from the wild mouse species Mus castaneus were found to be uniquely resistant to exogenous infection by polytropic mink cell focus-forming (MCF) murine leukemia viruses (MuLVs). This MCF MuLV resistance is inherited as a genetically recessive trait in the progeny of F1 crosses between M. castaneus and MCF MuLV-susceptible laboratory mice. Examination of the progeny of backcrosses demonstrated that susceptibility is inherited as a single gene which maps to chromosome 1. The map location of this gene places it at or near the locus Rmc1, the gene encoding the receptor for MCF/xenotropic MuLVs, suggesting that resistance is mediated by the M. castaneus allele of this receptor.
研究发现,源自野生小鼠物种栗色小鼠(Mus castaneus)的培养细胞对多嗜性貂细胞集落形成(MCF)鼠白血病病毒(MuLVs)的外源感染具有独特的抗性。这种MCF MuLV抗性在栗色小鼠与MCF MuLV易感实验室小鼠的F1杂交后代中作为一种遗传隐性性状遗传。回交后代的检查表明,易感性作为一个单基因遗传,该基因定位于1号染色体。该基因的图谱位置表明它位于Rmc1基因座或其附近,Rmc1基因编码MCF/嗜异源性MuLVs的受体,这表明抗性是由该受体的栗色小鼠等位基因介导的。
