| Summary |
Here we show that HNRNPU, the major nuclear matrix attachment factor, is necessary to maintain proper nuclear architecture in mouse hepatocytes. Upon HNRNPU depletion, the interactions between chromatin and nuclear lamina have been changed dramatically；chromatin organization is globally changed; boundaries of topologically associating domains (TADs) become weaker; inter-TAD interactions are increased; thousands of genes are significantly altered coincident with 3D chromatin changes. Mechanically, HNRNPU interacts with CTCF and RAD21, which affects the binding of RAD21 to the chromatin significantly, whereas CTCF bindings are almost unchanged, what’ more, the decrease of binding strengths are highly correlated with the weakness of loop bounded by Rad21. Taken together, we identify HNRNPU as a key regulator of chromatin architecture, and our data suggest the importance of nuclear matrix associating factors in 3D genome organization.
