对小鼠 1 型腺病毒 (MAV-1) 易感性的菌株特异性差异与小鼠 15 号染色体上的数量性状基因座 Msq1 相关。该区域包含 14 个 Ly6 或 Ly6 相关基因,其中许多已知在免疫细胞表面表达,表明可能在宿主防御中发挥作用。我们分析了这些基因的 MAV-1 易感和 MAV-1 抗性近交小鼠品系之间的多态性。 cDNA 测序鉴定出 2010109I03Rik、Ly6e、Ly6a、Ly6c1 和 Ly6c2 中的 12 个编码区多态性,其中 6 个是非同义的,其中 5 个先前未在 dbSNP Build 132 中列出。我们还澄清了 GenBank 中 I830127L07Rik 和 Ly6g 编码区的序列差异。此外,Southern 印迹揭示了 Ly6e、Ly6a 和 Ly6g DNA 区域内的大小多态性。总的来说,这些遗传变异对 Ly6 和 Ly6 相关基因的结构、功能和/或表达有影响,这些基因可能导致观察到的对 MAV-1 易感性的菌株特异性差异。
Strain-specific differences in susceptibility to mouse adenovirus type 1 (MAV-1) are linked to the quantitative trait locus Msq1 on mouse chromosome 15. This region contains 14 Ly6 or Ly6-related genes, many of which are known to be expressed on the surface of immune cells, suggesting a possible role in host defense. We analyzed these genes for polymorphisms between MAV-1-susceptible and MAV-1-resistant inbred mouse strains. Sequencing of cDNAs identified 12 coding region polymorphisms in 2010109I03Rik, Ly6e, Ly6a, Ly6c1, and Ly6c2, six of which were non-synonymous and five of which were previously unlisted in dbSNP Build 132. We also clarified sequence discrepancies in GenBank for the coding regions of I830127L07Rik and Ly6g. Additionally, Southern blotting revealed size polymorphisms within the DNA regions of Ly6e, Ly6a, and Ly6g. Collectively, these genetic variations have implications for the structure, function, and/or expression of Ly6 and Ly6-related genes that may contribute to the observed strain-specific differences in susceptibility to MAV-1.
