TP53 knockdown and knockout, as measured

DDB2 is lower after TP53 knockdown in all 14 screens that measured it and TPX2 is higher in 12 of 14; 6 of the 15 screens that knocked TP53 down have responses consistent within the screen (filled circles under the figure). The knockout screens of TP53 are shown apart from them, never combined.

Tap a cell or a screen name to read it here.

Arrow keys move between cells and the value is read out above the figure. Home and End go to the ends of a row, Enter shows the screens of a folded column. The table view lists every value.

13 of 18 screens drawn.

The gene names and the combined change stay in place while the screens scroll sideways.

Folding changes only what is drawn: Combined and Agree count every screen.

What it answers

  • What does knocking down or out my gene do?

    Every screen that knocked it down or out, the genes that moved, and whether each screen's response is consistent within it.

  • What changes my gene?

    The reverse lookup: which knockdowns or knockouts raised or lowered its expression, across the screens that measured it.

  • Does the evidence hold in my cells?

    Whether it comes from your cell line, from other lines, or does not exist, and how often evidence of that kind was confirmed by an independent study.

  • Which knockdowns or knockouts mimic or reverse my signature?experimental

    Paste the genes that go up and down in your experiment; measured knockdowns or knockouts are ranked by how they match or oppose them. A ranking only.
