PrimPol is required for replicative tolerance of G quadruplexes in vertebrate cells [PDF]

open access: yes, 2016
G quadruplexes (G4s) can present potent blocks to DNA replication. Accurate and timely replication of G4s in vertebrates requires multiple specialized DNA helicases and polymerases to prevent genetic and epigenetic instability.

A GLUTAMATE CYSTEINE LIGASE Gene StGSH1 Regulated by StERF10 Enhanced Glutathione Accumulation and Adaptation to Low Phosphorus Stress in Potato

open access: yesAdvanced Science, EarlyView.
The StERF10‐StGSH1 module coordinates glutathione (GSH) biosynthesis under low‐phosphorus stress. The low‐phosphate‐induced AP2/ERF transcription factor StERF10 directly activates the transcription of StGSH1 and enhances GSH accumulation. Consequently, GSH scavenges reactive oxygen species and provides sulfur for sulfolipid synthesis, facilitating the ...

Endometrial Assembloid Model Reveals Endometrial Gland Development Regulation by Estradiol‐Driven WNT7B Suppression

open access: yesAdvanced Science, EarlyView.
This study developed a 3D endometrial assembloid model to study how uterine glands form and develop. They discovered key interactions between different cell types and identified WNT7B as a regulator controlled by estradiol‐mediated TGFβ1‐VDR interaction.

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

open access: yeseLife, 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 ...

DCAF12 Ubiquitin Ligase Promotes Lung Cancer Metastasis by Modulating the TRiC/CCT Chaperonin Complex

open access: yesAdvanced Science, EarlyView.
This study elucidates how DCAF12 facilitates non‐degradative ubiquitination to stabilize TRiC/CCT, thereby enhancing the folding capacity of chaperonins. This mechanism promotes the maturation of cytoskeletal proteins and activates key oncogenic drivers, including YAP, STAT3, and mTOR, ultimately driving metastatic progression in lung cancer.

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

open access: yesFrontiers 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.

Cinnamic‐Hydroxamic‐Acid Derivatives Exhibit Antibiotic, Anti‐Biofilm, and Supercoiling Relaxation Properties by Targeting Bacterial Nucleoid‐Associated Protein HU

open access: yesAdvanced Science, EarlyView.
Cinnamic‐hydroxamic‐acid derivatives (CHADs) are identified as novel inhibitors of the bacterial nucleoid‐associated protein HU, exhibiting potent antibacterial, anti‐biofilm (both inhibition and eradication), and DNA relaxation (anti‐supercoiling) activities. Moreover, CHADs demonstrate strong synergistic effects with multiple antibiotics.

Roles for DNA polymerase δ in initiating and terminating leading strand DNA replication

open access: yesNature Communications, 2019
DNA polymerases epsilon and delta, respectively, perform the majority of leading and lagging strand replication of the eukaryotic nuclear genome. Here the authors map the ribonucleotide fingerprints of the polymerases to show the special roles of ...

Initiation of bacteriophage T4 DNA replication and replication fork dynamics: a review in the Virology Journal series on bacteriophage T4 and its relatives

open access: yesVirology Journal, 2010
Bacteriophage T4 initiates DNA replication from specialized structures that form in its genome. Immediately after infection, RNA-DNA hybrids (R-loops) occur on (at least some) replication origins, with the annealed RNA serving as a primer for leading ...

Geometrically Encoded Positioning of Introns, Intergenic Segments, and Exons in the Human Genome

open access: yesAdvanced Science, EarlyView.
This study introduces a new hypothesis: exons, introns, and intergenic segments are non‐random projections of the functional layers of 3D structure of chromatin packing domains. Evidence is presented that this “geometric code” may encode volumetric structure, reconciling epigenetic patterns, correlates with oncogenic mutations, acting as a potential ...
