The S-Phase Arrest of Host Cells Caused by an Alpha-Herpesvirus Genome Replication Facilitates Viral Recruitment of RNA Polymerase II to Transcribe Viral Genes.

Herpesviruses rely on host RNA polymerae II (RNA Pol II) for their mRNA transcription, yet the mechanisms of which has been poorly defined, while certain herpesviruses can enhance viral gene transcription by altering the RNA Pol II location, modulating its phosphorylation, or directly interacting with RNA Pol II. However, the influence of herpesviruses on RNA Pol II transcription extends beyond these direct effects. Here, we present a novel mechanism by which the host cell cycle regulates viral gene transcription via RNA Pol II during infection by Anatid Herpesvirus 1 (AnHV-1), an avian alpha-herpesvirus.

Gonadotropin Releasing Hormone Agonists Combined with Hormone Replacement Therapy Significantly Improves Reproductive Outcomes for Patients with Thin Endometrium and Intramural Fibroids in Frozen Embryo Transfer Cycles.

Background: Both intramural myomas and thin endometrium exert a detrimental influence on the outcomes of assisted reproductive technology (ART). The downregulation of gonadotropin releasing hormone agonists (GnRH-a) is regarded as an effective approach to reducing the size of intramural fibroids and enhancing endometrial receptivity. Consequently, we conducted this study to assess whether the GnRH-a combined with hormone replacement therapy (GnRH-a-HRT) can improve reproductive outcomes in frozen embryo transfer cycles for patients with a thin endometrium (≤7 mm) and intramural fibroids.

In-Plane Polarization-Triggered WS-Ferroelectric Heterostructured Synaptic Devices.

To date, various kinds of memristors have been proposed as artificial neurons and synapses for neuromorphic computing to overcome the so-called von Neumann bottleneck in conventional computing architectures. However, related working principles are mostly ascribed to randomly distributed conductive filaments or traps, which usually lead to high stochasticity and poor uniformity. In this work, a heterostructure with a two-dimensional WS monolayer and a ferroelectric PZT film were demonstrated for memristors and artificial synapses, triggered by in-plane ferroelectric polarization.

Cross-Talk between NOK and EGFR: Juxtamembrane and Kinase domain interactions enhancing STAT3/5 signaling in breast cancer tumorigenesis.

Epidermal growth factor receptor (EGFR) plays an important role in the regulation of cell proliferation and migration [1]. It forms a homodimer or heterodimer with other ErbB receptor family members to activate downstream signaling. Emerging evidence indicates that the EGFR activity and downstream signaling are regulated by other proteins except its family members during tumorigenesis.

Serendipitous Discovery of Dearomatized Dimers in Anthracene Derivative Oxidation.

We present the serendipitous discovery of an unusual dimer formed from anthracene-derived polyarenes. Unlike the typical oxidative coupling of substituted aromatic scaffolds, the reaction yielded a dearomatized enone dimer as the sole product.

DCAF13-mediated K63-linked ubiquitination of RNA polymerase I promotes uncontrolled proliferation in Breast Cancer.

Hyperactivation of ribosome biogenesis (RiBi) drives cancer progression, yet the role of RiBi-associated proteins (RiBPs) in breast cancer (BC) is underexplored. In this study, we perform a comprehensive multi-omics analysis and reveal that assembly and maturation factors (AMFs), a subclass of RiBPs, are upregulated at both RNA and protein levels in BC, correlating with poor patient outcomes. In contrast, ribosomal proteins (RPs) do not show systematic upregulation across various cancers, including BC.

Stereoselective Vinylogous Aza-Pummerer Reaction of β,β-Disubstituted Enesulfinamides.

Treatment of multisubstituted NH-enesulfinamides with tosyl isocyanate (TsNCO) at room temperature results in the formation of α-tosylcarbamoyloxy -sulfenyl ketimines with high enantioselectivity. This process is believed to proceed via a vinylogous aza-Pummerer-type reaction pathway in which the sulfinyl oxygen atom in the enesulfinamides undergoes nucleophilic attack on tosyl isocyanate, triggering the subsequent transformations that enable the transfer of chirality from sulfur to carbon.

Transcytosis: an effective mechanism to enhance nanoparticle extravasation and infiltration through biological barriers.
