Type II Alveolar Epithelial Cells Promote Sepsis‐Induced Immunosuppression in Alveolar Macrophages via Exosomal lncRNA Rmrp Release

Advanced Science, EarlyView.
The S100A4/STAT3 axis promotes Rmrp transcription in AEC‐IIs and Rmrp expression in AEC‐II‐derived exosomes. Upon entry into AMs, Rmrp binds to and blocks the ubiquitination and degradation of ZFP36. Increased ZFP36 induced Pfkfb3 mRNA decay by binding to AREs in the 3′ UTR, curbing glycolysis and immune responses of AMs and aggravating SII and ...

SUMOylated ORC2 Recruits a Histone Demethylase to Regulate Centromeric Histone Modification and Genomic Stability

Cell Reports, 2016
Origin recognition complex 2 (ORC2), a subunit of the ORC, is essential for DNA replication initiation in eukaryotic cells. In addition to a role in DNA replication initiation at the G1/S phase, ORC2 has been shown to localize to the centromere during ...

The GGH/HuR Complex Binds and Stabilizes mRNAs to Maintain Tumor Cell Cycle and DNA Replication

Advanced Science, EarlyView.
Despite its canonical role in inhibiting DNA synthesis, GGH promotes tumor growth as a novel RNA‐binding protein. GGH binds GC‐rich 5′UTRs (e.g., CDC6/CCND1), recruits HuR to form a ternary complex that stabilizes mRNA via circular conformation, fueling DNA replication and the cell cycle. Targeting this axis suppresses NSCLC progression.

TRAIP drives replisome disassembly and mitotic DNA repair synthesis at sites of incomplete DNA replication

eLife, 2019
The faithful segregation of eukaryotic chromosomes in mitosis requires that the genome be duplicated completely prior to anaphase. However, cells with large genomes sometimes fail to complete replication during interphase and instead enter mitosis with ...

Effect of Additional Terminal Residues on the Folding and Unfolding Dynamics of Cold Shock Protein

Advanced Science, EarlyView.
Enhancing protein stability through N‐ and C‐terminal modifications presents a safe and cost‐effective strategy. We investigated this by combining single‐molecule magnetic tweezers experiments and molecular dynamics simulations to study the folding and unfolding dynamics of CSP with various appended residues (LE‐CSP‐GS, KL‐CSP‐GS, KL‐CSP‐LE).

Dynamic relocalization of replication origins by Fkh1 requires execution of DDK function and Cdc45 loading at origins

eLife, 2019
Chromosomal DNA elements are organized into spatial domains within the eukaryotic nucleus. Sites undergoing DNA replication, high-level transcription, and repair of double-strand breaks coalesce into foci, although the significance and mechanisms giving ...

Single‐Cell Transcriptomics Unravels Growth Factor Erv1‐Like Mediated Ferroptosis as a Key Driver of Intestinal Epithelial Dysfunction in Ulcerative Colitis

Advanced Science, EarlyView.
Single‐cell transcriptomic profiling of ulcerative colitis (UC) tissues identified downregulation of GFER in intestinal epithelial cells. Mechanistically, GFER interacts with PCBP1 to help maintain intracellular iron homeostasis and may also reduce lipid peroxidation by activating the PGC‐1α/PPARγ signaling pathway, thereby inhibiting ferroptosis ...

Replicon: a software to accurately predict DNA replication timing in metazoan cells

Frontiers in Genetics, 2014
Eukaryotic DNA replication follows a strict temporal program where genomicloci are replicated at precise times during the S phase of the cellcycle. Yet, the mechanism in control of the timing program in metazoan cellsis poorly understood.
