Overexpression of the pioneer transcription factor Nr5a2 promotes the development of mouse somatic cell nuclear transfer embryos
Somatic Cell Nuclear Transfer (SCNT) is an approach that enables the generation of an embryo from a somatic cell, but its efficiency remains low due to epigenetic barriers. This study shows that pione...

Our first cell-free DNA paper is now published! Thank you to all co-authors and collaborators for their contributions.
Officially published in Communications Biology!
In this study, we developed an open chromatin-guided, interpretable machine learning pipeline to uncover cancer-specific nucleosomal fragment patterns directly from cell-free DNA.

Our study with Anjana Rao's lab was just published at NSMB 🥳 Shows how OGT prevents TET proteins from activating retrotransposons, particularly those in heterochromatin. Paper has 6-base and ONT sequencing data from OGT iKO mESCs, and also interesting OGT inhibitor data 👀.

OGT prevents DNA demethylation and suppresses the expression of transposable elements in heterochromatin by restraining TET activity genome-wide
Nature Structural & Molecular Biology - Here the authors show that the disruption of OGT expression in mouse embryonic stem cells unleashes TET activity, causing genome-wide decreases in DNA...
