Global transcriptome analysis of paracancerous lung tissues from the B16 metastasis mice model under the influence of lactoferrin knockout

Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are using transcriptome profiling (RNA-seq) to evaluate the effects of lactoferrin deficiency on the global transcriptome of the lung microenvironment of the B16 metastasis mice model. Methods: 2×10^5 B16-F10 cells were injected into WT and lactoferrin kncoutout (Lf-/-) mice (each group has 10 eight-weeks-old male mice) through tail vein. At 3 weeks post injection,the paracancerous lung tissue were isolated (not including any metastatic colonies). RNAs were extracted by Trizol and sequenced by Solexa high-throughput sequencing service (Oebiotech, Shanghai, China). Data were extracted and normalized according to the manufacturer’s standard protocol.Each group has two mice paracancerous lung tissues be tested. Results: There are significant gene expression profile changes between WT and Lf-/- tumor-bearing mice. Conclusions: Our study describes the global transciptome changes of paracancerous lung tissues from the B16 metastasis mice model under the influence of lactoferrin kncokout. Mice paracancerous lung tissues mRNA profiles of “WT” (wild type), “KO”(lactoferrin konckout, Lf-/-) were generated by RNA sequecning, using Solexa high-throughput sequencing service (Oebiotech, Shanghai, China).
