Compositions for glioma classification
View Patent ↗The present invention provides novel compositions and their use in classifying gliomas. In a preferred embodiment, the methods are used to discriminate between oligodendroglioma and glioblastoma.
1. An isolated composition consisting of between 3 and 47 different probe sets, wherein a first probe set consists of one or more probes consisting of 20 or more contiguous nucleotides of SEQ ID NO:3 or a full complement thereof and optionally a detectable label, a second probe set consists of one or more probes consisting of 20 or more contiguous nucleotides of SEQ ID NO:5 or a full complement thereof and optionally a detectable label, and a third probe set consists of one or more probes consisting of 20 or more contiguous nucleotides of SEQ ID NO:7 or a full complement thereof and optionally a detectable label, and wherein each of the between 3 and 47 different probe sets consists of one or more probes consisting of 20 or more contiguous nucleotides, or full complements thereof, of a single mRNA different from that of the other probe sets, and optionally a detectable label.
2. The isolated composition of claim 1 wherein the composition consists of between 4 and 47 different probe sets.
3. The isolated composition of claim 1 wherein the composition consists of between 5 and 47 different probe sets.
4. The isolated composition of claim 1 wherein the probes further comprise a detectable label.
5. The isolated composition of claim 1 wherein the composition consists of 3-23 different probe sets.
6. The isolated composition of claim 1 , wherein the composition consists of 3-5 different probe sets.
7. The isolated composition of claim 4 , wherein the detectable labels on the probes of one probe set are distinguishable from the detectable labels on the probes of the other probe sets.
8. The isolated composition of claim 1 , wherein the first probe set consists of one or more probes consisting of 500 or more contiguous nucleotides of SEQ ID NO:3 or a full complement thereof, the second probe set consists of one or more probes consisting of 500 or more contiguous nucleotides of SEQ ID NO:5 or a full complement thereof, and the third probe set consists of one or more probes consisting of 500 or more contiguous nucleotides of SEQ ID NO: 7 or a full complement thereof.
9. The isolated composition of claim 5 wherein the probes further comprise a detectable label.
10. The isolated composition of claim 6 wherein the probes further comprise a detectable label.
11. The isolated composition of claim 9 , wherein the detectable labels on the probes of one probe set are distinguishable from the detectable labels on the probes of the other probe sets.
12. The isolated composition of claim 10 , wherein the detectable labels on the probes of one probe set are distinguishable from the detectable labels on the probes of the other probe sets.
13. The isolated composition of claim 8 wherein the probes further comprise a detectable label.
14. The isolated composition of claim 13 , wherein the detectable labels on the probes of one probe set are distinguishable from the detectable labels on the probes of the other probe sets.
