Correction: Replication of BRIT1/MCPH1 G2/M Checkpoint Function Confirms Original Conclusions

Show abstract
In our 2005 PNAS publication1, we reported that BRIT1/MCPH1 is required for proper activation of the G2/M checkpoint in response to DNA damage. A recent analysis using image comparison software, Proofig, identified a duplicated panel in Figure 2A, stemming from a figure assembly error in which data from a prior experiment involving a different gene (Claspin)2 were inadvertently reused. As the original data are no longer accessible due to the age of the experiment, we have independently repeated the G2/M checkpoint analysis. The new results fully confirm the original conclusion: BRIT1 depletion compromises G2/M arrest following ionizing radiation. This replication supports the integrity of our original findings and is provided in support of a formal correction requested by PNAS.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
