Avalilação PREreview de FOXA2 potently represses viral gene expression by targeting NF-κB–dependent transcription in liver cells

Write a short summary of the research’s main findings and how this work has moved the field forward.

Major issues:

• ATAC-seq: The study would benefit from clearer evidence showing that enhancers are closed in wild-type (WT) conditions and become accessible primarily in FOXA2^low contexts, to support conclusions about chromatin accessibility dynamics.

• CUT&Tag: It is important to further clarify whether enhancer occupancy by transcription factors is restricted to FOXA2-deficient conditions, and how FOXA2 presence, even at low levels, contributes to enhancer repression.

• CRISPR deletion: Functional deletion of candidate enhancers suggests enhancer-specific regulation; however, additional validation across multiple loci would strengthen the generalizability of enhancer-specific control.

Minor issues:

• The study appears to rely heavily on Western blot analyses, which may not be sufficient on their own to fully support conclusions related to chromatin state and transcriptional regulation.

• Control conditions are not always explicitly demonstrated or clearly described across experiments, which may limit the interpretation of causality in some of the reported findings.
