Lnc-Cancer Score

Get an overview of Lnc-Cancer_Score.


Score= N*(C+B+T)

N:the number of lncRNA-cancer association for your search

C:0 or 1; if the lncRNA-cancer association had been verified in cancer cell lines.

B:0 or 1; if the lncRNA-cancer association had been verified in cancer blood.

T:0 or 1; if the lncRNA-cancer association had been verified in cancer tissues.



e.g. The association between MALAT1 and multiple myeloma are verified in 7 publications. For the publication numbered 25369863, MALAT1 is associated with multiple myeloma verified in tissue. Thus we calculate the score as follow:

Score=7*(0+0+1)=7


Figure 7-1:

1. Users can input an interested lncRNA or/and cancer name.

2. The number of lncRNA-cancer verified entries in Lnc2Cancer 2.0 for your search.

3. If the lncRNA-cancer association had been verified in cancer cell lines, tissues and blood.

4. The scores for the lncRNA-cancer associations. Users could rank the lncRNA-cancer association by scores.
