ZBTB12-HERVH-LncRNA axis is a molecular barrier for dedifferentiation of human stem cells

Project description:Development is generally viewed as one-way traffic of cell state transition from primitive to developmentally advanced states. However, molecular mechanisms that ensure the unidirectional transition remain largely unknown. NanoCAGE sequencing identified an evolutionarily conserved zinc finger repressor, ZBTB12, as a molecular barrier for dedifferentiation of human pluripotent stem cells (hPSCs). Single cell RNA sequencing revealed that ZBTB12 is essential for three germ layer differentiation by blocking hPSC dedifferentiation. Mechanistically, ZBTB12 cooperates with NANOG to fine-tune the expression of human endogenous retroviruses (HERVs). Active HERVH loci drive the expression of overlapping long non-coding RNAs (lncRNAs) whose downregulation by ZBTB12 is necessary for dedifferentiation blockage and pluripotency exit. Overall, we have identified a ZBTB12-HERVH-lncRNA axis as molecular machinery that safeguards the unidirectional transition of stem cell fates.

Single cell RNA sequencing revealed that ZBTB12 is essential for three germ layer differentiation by blocking hPSC dedifferentiation. Mechanistically, ZBTB12 serves as a master repressor of human endogenous retrovirus H (HERVH). Active HERVH loci drive the expression of overlapping long non-coding RNAs (lncRNAs) whose downregulation by ZBTB12 is necessary for pluripotency exit and lineage derivation.

ZBTB12 is a molecular barrier to dedifferentiation in human pluripotent stem cells.

Project description:Development is generally viewed as one-way traffic of cell state transition from primitive to developmentally advanced states. However, molecular mechanisms that ensure the unidirectional transition of cell fates remain largely unknown. Through exact transcription start site mapping, we report an evolutionarily conserved BTB domain-containing zinc finger protein, ZBTB12, as a molecular barrier for dedifferentiation of human pluripotent stem cells (hPSCs). Single-cell RNA sequencing reveals that ZBTB12 is essential for three germ layer differentiation by blocking hPSC dedifferentiation. Mechanistically, ZBTB12 fine-tunes the expression of human endogenous retrovirus H (HERVH), a primate-specific retrotransposon, and targets specific transcripts that utilize HERVH as a regulatory element. In particular, the downregulation of HERVH-overlapping long non-coding RNAs (lncRNAs) by ZBTB12 is necessary for a successful exit from a pluripotent state and lineage derivation. Overall, we identify ZBTB12 as a molecular barrier that safeguards the unidirectional transition of metastable stem cell fates toward developmentally advanced states.
