Dear DepMap experts, I am using DepMap to show the dependency of various cancer to LDLR. I have following questions:
- What is the standard of reporting Chronos number, I mean is there a level of significance we can report? For example, is 0.3 Gene effect (Chronos) number quite good to report as a cancer dependence gene or numbers beyond -1 and lesser are more powerful and should be reported? I do see a red line in the graph at -1 position only, is that a minimum threshold a gene should show to pass as a cancer dependency gene or any number below 0 is also good?
- Also, to qualify as a pan essential gene, the Chronos number should be -1 or below always? For example in the attached graph LDLR could qualify as a pan essential gene in the blood cancer but not in the others??
- For example in Cervix cancer, the expression of LDLR is high (TPM~5) but the gene effects number is low (only 0.2), does it mean although the level of LDLR is high in cervix cancer but its knock out does not affect cancer cell viability. Not sure how to say it in terms of statistics, can we say it has significant affect on viability but moderate.
- Can I get a reference where DepMap was used to to show the importance of a single gene, like I want to show the importance of LDLR. This would help me to write my results.
Thank you for making such a nice database. I am looking forward to hear back from you.
