SEC Mediates m6A Deposition and Transcription Pause Release to Drive Cell Identity Transition

open access: yesAdvanced Science, EarlyView.
The SEC promotes cell identity transitions by facilitating transcription pause release at key identity‐associated genes, including Klf4 and Myc during iPSC reprogramming and Nes and Tubb3 during ESC‐to‐neuroectodermal differentiation. During early iPSC reprogramming, this function additionally involves cooperation with METTL3‐associated m6A regulation.

ELF5‐Mediated Enhancer–Promoter Interaction Regulates LALBA Expression in Ovine Mammary Gland

open access: yesAdvanced Science, EarlyView.
In the study, we systematically investigate the epigenetic mechanisms underlying lactation traits in sheep by integrating transcriptomic, chromatin accessibility, histone modification, and functional analyses. We identify a super‐enhancer at the LALBA locus and demonstrate that enhancer E4 functions as its core regulatory element.

H4K12 Lactylation Impairs Dopaminergic Neuron Energy Metabolism via the HIF‐1α/NDUFS1 Pathway in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
Lactate and H4K12la are elevated in Parkinson's disease. Mechanistically, p300‐mediated H4K12la enrichment at the HIF‐1α promoter upregulates HIF‐1α, which represses Ndufs1, impairing mitochondrial respiration and energy homeostasis in DA neurons.

HADHA K406 Lactylation Regulates Metabolic Reprogramming and Suppresses Immune Responses in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
HADHA K406 lactylation fuels fatty acid β‐oxidation and HMGCR‐dependent cholesterol biosynthesis, fostering immunosuppressive MDSCs and exhausted CD8+ T cells in gastric cancer. Loss of this modification blocks cholesterol production, remodels the tumor microenvironment, and tumor growth is suppressed via combined inhibition of HMGCR and LDHA ...

TP53 R249S mutation in hepatic organoids captures the predisposing cancer risk

open access: yesHepatology, EarlyView., 2022
The systematic approach in elucidating the gain‐of‐function (GOF) roles of TP53 mutations in early liver carcinogenesis. Unique downstream targets of TP53 L3 mutations were identified from chormatin immunoprecipitation sequencing in HCC cell lines, followed by a series of validation assays to substantiate the exclusive transcriptional regulations ...
