Calculating Biological Behaviors of Epigenetic States in Phage lambda Life Cycle [PDF]

open access: yes, 2004
Gene regulatory network of lambda phage is one the best studied model systems in molecular biology. More 50 years of experimental study has provided a tremendous amount of data at all levels: physics, chemistry, DNA, protein, and function.

Multiphysics‐Driven Assembly of Biomimetic Vesicles

open access: yesAdvanced Materials, EarlyView.
Artificial extracellular vesicles, derived from cell membranes, are manufactured using a multiphysics‐integrated microfluidic platform that combines nanoknife membrane rupture, herringbone chaotic mixing, and acoustothermal modulation. This standardizable workflow enables the predictable control of vesicle formation and therapeutic loading, while ...

Comparative ribosome profiling uncovers a dominant role for translational control in Toxoplasma gondii

open access: yesBMC Genomics, 2017
Background The lytic cycle of the protozoan parasite Toxoplasma gondii, which involves a brief sojourn in the extracellular space, is characterized by defined transcriptional profiles.

Epstein‐Barr Virus Expressed Long Non‐Coding RNA (lncBARTs) Regulate EBV Latent Genome Replication

open access: yesAdvanced Science, EarlyView.
EBV produces abundant level of lncBARTs, which are essential for maintaining viral genome replication in EBV‐associated cancers. LncBARTs interact with a complex comprising BRD4, CTCF and viral protein EBNA1 at EBV oriP region. This interaction tethers oriP to host chromosomes, facilitating EBV episome replication.

The role of EBV lytic genes in tumor development and progression

open access: yesGuangxi Yike Daxue xuebao
Epstein-Barr virus (EBV), the first human oncolytic virus, is the causative agent of several cancers of epithelial and lymphoid origin. The life cycle of EBV consists of two phases, the latent and lytic phases.

Complexities associated with expression of Epstein-Barr virus (EBV) lytic origins of DNA replication. [PDF]

open access: yes, 2007
EBV has two lytic origins (oriLyt) of DNA replication lying at divergent sites on the viral genome within a duplicated sequence (DS). The latter contains potential hairpin loops, ‘hinge’ elements and the promoters for transcripts from viral genes BHLF1 ...

Inhibition of the Epstein–Barr virus lytic cycle by protoapigenone

open access: yesJournal of General Virology, 2011
Epstein–Barr virus (EBV) expresses two transcription factors, Rta and Zta, during the immediate–early stage of the lytic cycle to activate the transcription of early and late genes. This study finds that 0.31 mM protoapigenone fromThelypteris torresiana(Gaud.) inhibits the expression of EBV lytic proteins, including Rta, Zta, EA-D and VCA, in P3HR1 ...

Development of Endogenous Protein Probes for Characterizing Surface Proteins and Cellular Interactors of Extracellular Vesicles

open access: yesAdvanced Science, EarlyView.
The proximity labeling enzyme APEX2 is displayed on extracellular vesicle (EV) surfaces via genetic fusion with EV‐sorting scaffolds, enabling in situ biotinylation of native surface proteins, adsorbed corona components, and interacting cellular proteins.

An HIV feedback resistor: auto-regulatory circuit deactivator and noise buffer. [PDF]

open access: yes, 2006
Animal viruses (e.g., lentiviruses and herpesviruses) use transcriptional positive feedback (i.e., transactivation) to regulate their gene expression.

Soybean Auxin Transporter PIN3 Regulates Nitrate Acquisition to Improve Nitrogen Use and Seed Traits

open access: yesAdvanced Science, EarlyView.
Xu et al. discovers that switching off auxin transporters in soybean, PIN3a and PIN3b, disrupts auxin flow; this triggers ARF‐STF3/4 signal cascade to activate the nitrate importer NPF2.13 and soil nitrogen acquisition. Multi‐year field trials show edited soybeans maintain yield with higher oil content, offering a potential genetic route to improve ...
