DPV pUL15 possesses a potential NLS, which is important for the location of the terminase complex and for viral proliferation and genome cleavage.

In herpesvirus, the terminase subunit pUL15 is involved in cleavage of the viral genome concatemers in the nucleus. Previous studies have shown that herpes simplex virus 1 (HSV-1) pUL15 can enter the nucleus without other viral proteins and help other terminase subunits enter the nucleus. However, this study revealed that duck plague virus (DPV) pUL15 cannot localize independently to the nucleus and can only be localized in the nucleus in the presence of pUL28 and pUL33.

Knockout or inhibition of DHPS suppresses ovarian tumor growth and metastasis by attenuating the TGFβ pathway.

Deoxyhypusine synthase (DHPS) is an enzyme encoded by the DHPS gene, with high expression in various cancers, including ovarian cancer (OC). DHPS regulates the translation initiation factor EIF5A, and EIF5A2 knockout inhibits OC tumor growth and metastasis by blocking the epithelial-to-mesenchymal transition (EMT) and the TGFβ pathway. In this study, we show that DHPS is amplified in OC patients, and its elevated expression correlates with poor survival.

MiR-675 Inhibits Primary Ovarian Tumor Growth and Metastasis by Suppressing EMT and TGFβ Signaling.

MicroRNAs (miRNAs) can function as either tumor suppressors or oncogenes. This study explores the role of miR-675 in ovarian cancer (OC) using OC cell lines and an orthotopic mouse model. We demonstrate that miR-675 expression inhibits primary tumor growth and metastasis by targeting TGFβ1, suppressing epithelial to mesenchymal transition (EMT), and attenuating the TGFβ signaling pathway.

R2R3-MYB transcription factors RrMYB12 and RrMYB111 regulate the accumulation of flavonols and anthocyanins.

Roses () are a famous flower with high ornamental and economic value. But the petals of roses are usually pink and purple, which restricted its application in garden settings. Flavonols and anthocyanins are crucial secondary metabolites related to flower pigmentation in plants.

Characteristics of OSA modified starch-based Pickering emulsion and its application to myofibrillar protein gel.

Background: Pickering emulsions prepared with octenyl succinic anhydride-modified starch (OSAS) show significant promise as replacements for animal fat. However, the underlying mechanism of incorporating an OSAS-based Pickering emulsion into a myofibrillar protein (MP) gel and its impact on the gel properties remain poorly understood. In this study, the effects of OSAS at varying concentrations (0-10.

The characterization of outer membrane vesicles (OMVs) and their role in mediating antibiotic-resistance gene transfer through natural transformation in Riemerella anatipestifer.

Riemerella anatipestifer (R. anatipestifer, RA) is the etiological agent of duck serositis, an acute multisystemic disease in ducks that is globally distributed and causes serious economic losses in the duck industry. Despite exhibiting multidrug resistance, the transmission mechanism of its antibiotic resistance genes (ARGs) remains incompletely identified.

DHAV-1 3C protein promotes viral proliferation by antagonizing type I interferon via upregulating the ANXA2 protein.

The picornavirus 3C protein plays a crucial role in viral infection. One of its functions is inhibiting the immune response by cleaving or degrading innate immune-related proteins to promote viral infection. Annexin A2 (ANXA2) is a multifunctional host protein that plays a key role in various cellular processes, it also participates in viral infection.

Decoding the enigma: unveiling the transmission characteristics of waterfowl-associated -positive in select regions of China.

() serves as a critical indicator microorganism for assessing the prevalence and dissemination of antibiotic resistance, notably harboring various antibiotic-resistant genes (ARGs). Among these, the emergence of the gene represents a significant threat to public health, especially since carbapenem antibiotics are vital for treating severe infections caused by Gram-negative bacteria. This study aimed to characterize the antibiotic resistance features of -positive strains isolated from waterfowl in several regions of China and elucidate the dissemination patterns of the gene.

tRNA-Ser-UGA efficiently promotes the rapid release of duck hepatitis A virus from infected enterocytes and its remote dissemination to hepatocytes.

Enterocytes are a necessary portal for fecal-oral transmission of viruses, including duck hepatitis A virus (DHAV), that act on the absorption of amino acids (AAs). We note that the rapid death of ducklings caused by DHAV is likely due to its rapid release from enterocytes. However, the underlying mechanism driving the release of DHAV remains poorly understood.

Identification and subcellular localization of proteins that interact with Duck plague virus pUL14 in infected host cells.

Duck plague (DP), which is caused by duck plague virus (DPV), is an infectious disease that severely harms the waterfowl breeding industry. The UL14 protein (pUL14) is a tegument protein encoded by the UL14 gene, which is located in the unique long (UL) region of the DPV genome. DPV pUL14 plays a crucial role in viral replication, likely by interacting with host and viral proteins that have yet to be identified.

Anti-tembusu virus of capsid-targeted viral inactivation delivered by lentiviral vector in vivo.

Tembusu virus (TMUV) is a member of genus flavivirus, which mainly causes decrease in production in egg ducks and neurological symptom in meatducks, causing serious economic losses to the poultry industry. Recently, the commercialized TMUV vaccines are mainly the WF100 live vaccine and the attenuated live vaccine (FX2010-180P), so it is particularly important to find new methods to combat TMUV. The capsid-targeted viral inactivation (CTVI) strategy is based on a viral core protein and an exogenous factor that can destroy viral DNA or RNA.

Assessment of hypoxia and its dynamic evolution in glioblastoma via qBOLD MRI: a comparative study with metformin treatment.

Background: To investigate the accuracy of quantitative blood oxygen level-dependent (qBOLD) magnetic resonance imaging (MRI) in identifying hypoxia within glioblastoma and explore dynamic changes in oxygenation status of glioblastoma with and without metformin administration.

Methods: Three healthy and seven C6-bearing rats underwent 7-T qBOLD MRI. Oxygen extraction fraction (OEF) and cerebral metabolism rate of O (CMRO) were calculated from qBOLD data.

Identification on Key Volatiles Contributed to Oviposition Preference of (Hübner, 1813) (Lepidoptera: Pyralidae) from High and Normal Oleic Varieties of Peanut.

The Indian meal moth, (Hübner, 1813) (Lepidoptera: Pyralidae), a primary stored peanut insect pest, exhibited a significant difference in oviposition preference among normal-oleic peanuts (NOPs) and high-oleic peanuts (HOPs). Identifying key volatile organic compounds (VOCs) that are attractive or repellent to is of great significance for the ecological management of pests. The profiles and contents of VOCs among NOP and HOP varieties were measured and compared, and key bioactive VOCs were further confirmed via an electroantennogram (EAG) analysis, as well as behavioral responses in Y-tube olfactometer and wind tunnel bioassays.

Duck plague virus UL24 protein initiates K48/K63-linked IRF7 polyubiquitination to antagonize the innate immune response.

Duck plague virus (DPV), which is the causative agent of duck viral enteritis, is highly infectious and can cause severe disease and death in ducks, geese and other waterfowl. Several tegument proteins of DPV have been shown to affect the cyclic GMP-AMP synthase (cGAS)-STING signaling pathway to modulate host innate immune responses. DPV UL24, an important DPV tegument protein, can inhibit the activity of the IFN-β promoter.

PI4KB is an essential host factor for duck hepatitis a virus 1 replication and translation.

Duck hepatitis A virus 1 (DHAV-1) is one of the most serious pathogens endangering the duck industry. Phosphatidylinositol 4-kinases (PI4Ks) are important for viral replication, and different viruses have different strategies to hijack PI4Ks. To date, few studies have investigated the DHAV-1 life cycle; thus, whether PI4Ks are required for DHAV-1 replication has not been reported.
