| T1 |
0-89 |
Sentence |
denotes |
U87MG decoded: the genomic sequence of a cytogenetically aberrant human cancer cell line. |
| T2 |
90-216 |
Sentence |
denotes |
U87MG is a commonly studied grade IV glioma cell line that has been analyzed in at least 1,700 publications over four decades. |
| T3 |
217-483 |
Sentence |
denotes |
In order to comprehensively characterize the genome of this cell line and to serve as a model of broad cancer genome sequencing, we have generated greater than 30x genomic sequence coverage using a novel 50-base mate paired strategy with a 1.4kb mean insert library. |
| T4 |
484-600 |
Sentence |
denotes |
A total of 1,014,984,286 mate-end and 120,691,623 single-end two-base encoded reads were generated from five slides. |
| T5 |
601-754 |
Sentence |
denotes |
All data were aligned using a custom designed tool called BFAST, allowing optimal color space read alignment and accurate identification of DNA variants. |
| T6 |
755-1008 |
Sentence |
denotes |
The aligned sequence reads and mate-pair information identified 35 interchromosomal translocation events, 1,315 structural variations (>100 bp), 191,743 small (<21 bp) insertions and deletions (indels), and 2,384,470 single nucleotide variations (SNVs). |
| T7 |
1009-1180 |
Sentence |
denotes |
Among these observations, the known homozygous mutation in PTEN was robustly identified, and genes involved in cell adhesion were overrepresented in the mutated gene list. |
| T8 |
1181-1319 |
Sentence |
denotes |
Data were compared to 219,187 heterozygous single nucleotide polymorphisms assayed by Illumina 1M Duo genotyping array to assess accuracy: |
| T9 |
1320-1435 |
Sentence |
denotes |
93.83% of all SNPs were reliably detected at filtering thresholds that yield greater than 99.99% sequence accuracy. |
| T10 |
1436-1572 |
Sentence |
denotes |
Protein coding sequences were disrupted predominantly in this cancer cell line due to small indels, large deletions, and translocations. |
| T11 |
1573-1779 |
Sentence |
denotes |
In total, 512 genes were homozygously mutated, including 154 by SNVs, 178 by small indels, 145 by large microdeletions, and 35 by interchromosomal translocations to reveal a highly mutated cell line genome. |
| T12 |
1780-1884 |
Sentence |
denotes |
Of the small homozygously mutated variants, 8 SNVs and 99 indels were novel events not present in dbSNP. |
| T13 |
1885-2002 |
Sentence |
denotes |
These data demonstrate that routine generation of broad cancer genome sequence is possible outside of genome centers. |
| T14 |
2003-2124 |
Sentence |
denotes |
The sequence analysis of U87MG provides an unparalleled level of mutational resolution compared to any cell line to date. |
