Tick-borne encephalitis virus (TBEV) represents a pivotal tick-transmitted flavivirus responsible for severe neurological consequences in Europe and Asia. The emergence of TBEV genetic mutations and vaccine-breakthrough infections, along with the absence of effective vaccines and specific drugs for other tick-borne flaviviruses associated with severe encephalitis or hemorrhagic fever, underscores the urgent need for progress in understanding the pathogenesis and intervention strategies for TBEV and related flaviviruses. Here we elucidate cellular alterations in the proteome, phosphoproteome, and acetylproteome upon TBEV infection.

Tick-borne encephalitis virus (TBEV) is a significant viral pathogen transmitted by ticks, causing severe neurological complications in humans across Europe and Asia, highlighting the urgent need for an in-depth understanding of molecular functions of viral proteins and their interactions with the host proteome. Multi-omics analysis of how TBEV hijack cellular processes provides information about their replication and pathogenic mechanisms. Here, we focused on the proteome, phosphoproteome, and acetylproteome of Vero cells infected by TBEV, revealing the host perturbations triggered by TBEV infection.

As methicillin-resistant (MRSA) exhibits formidable resistance to many drugs, the imperative for alternative therapeutic strategies becomes increasingly evident. At the heart of our study is the identification of a novel inhibitor through fluorescence anisotropy assays, specifically targeting the crucial multiple gene regulator A (MgrA) regulatory network in . Isorhapontigenin (Iso), a natural compound, exhibits outstanding inhibitory efficacy, modulating bacterial virulence pathways without exerting direct bactericidal activity.

Pancreatic cancer, predominantly pancreatic ductal adenocarcinoma (PDAC), remains a highly lethal malignancy with limited therapeutic options and a dismal prognosis. By targeting the underlying molecular abnormalities responsible for PDAC development and progression, gene therapy offers a promising strategy to overcome the challenges posed by conventional radiotherapy and chemotherapy. This study sought to explore the therapeutic potential of small activating RNAs (saRNAs) specifically targeting the CCAAT/enhancer-binding protein alpha (CEBPA) gene in PDAC.

Diabetic nephropathy (DN) is one of the complications of diabetes mellitus and the main cause of end-stage renal disease (ESRD), which is a serious threat to human health. In DN, mesangial cells (MCs) are a critical target cell that perform a variety of key functions, and abnormal proliferation of MCs is a common and prominent pathological change in DN. In recent years, the investigation of Chinese medicine interventions for DN has increased significantly in recent years due to the many potential adverse effects and controversies associated with the treatment of DN with Western medicines.

Our primary objective was to investigate the protective effects and mechanisms of isovanillic acid in mice infected with Newman. coagulation assays were used to validate vWbp and Coa as inhibitory targets of isovanillic acid. The binding mechanism of isovanillic acid to vWbp and Coa was investigated using molecular docking and point mutagenesis.

Aims: The main purpose of this study was to study the therapeutical effect of oroxylin A glucuronide (OAG) on methicillin-resistant Staphylococcus aureus (MRSA).

Methods And Results: By substrate peptide reaction-based fluorescence resonance energy transfer (FRET) screening, we identified that OAG was an efficient inhibitor of Sortase A (SrtA) with an IC50 of 45.61 μg mL-1, and achieved efficacy in the treatment of Staphylococcus aureus (S.

Article Synopsis
  • The study identified hibifolin as an inhibitor of sortase A (SrtA), a key enzyme in the virulence mechanism of methicillin-resistant Staphylococcus aureus (MRSA).
  • Hibifolin was shown to effectively reduce SrtA activity, leading to decreased bacterial adhesion and biofilm formation, with a measured inhibitory concentration (IC) of 31.20 μg/mL.
  • When combined with cefotaxime, hibifolin provided enhanced protection against MRSA-induced pneumonia in mice, presenting a potential new therapeutic approach for treating S. aureus infections.

Article Synopsis
  • Hypopharyngeal squamous cell carcinoma (HSCC) has a high mortality rate, prompting research into new treatments like the natural compound solamargine (SM), which shows promise in reducing cancer cell proliferation.
  • SM significantly inhibits the growth of FaDU cells, particularly affecting the levels of specific non-coding RNAs involved in apoptosis, highlighting its potential role in cancer therapy.
  • Animal studies further confirm that SM not only induces apoptosis in cancer cells by altering non-coding RNA expression but also suppresses tumor growth in xenograft models, indicating its effectiveness against HSCC.

Article Synopsis
  • SARS-CoV-2, the virus responsible for COVID-19, is constantly evolving, indicating a need for new antiviral treatments.
  • A study using mass spectrometry identified significant changes in protein succinylation in both host and viral proteins during SARS-CoV-2 infection, specifically inhibiting important metabolic pathways.
  • The research highlights that the viral protein NSP14 regulates succinylation through SIRT5, and that targeting succinylation has potential as an antiviral strategy, as seen with the inhibition of virus replication and effects on the virus's structure.

Article Synopsis
  • The study focuses on the challenge of drug-resistant Staphylococcus aureus (S. aureus) and highlights hispidulin, which inhibits the hemolytic activity of the bacteria without affecting its growth or causing resistance.* -
  • Hispidulin demonstrated the ability to inhibit the transcription and expression of alpha-hemolysin (hla), a key virulence factor, and had a protective effect against cell damage caused by S. aureus in lab tests.* -
  • In animal studies, hispidulin showed effectiveness in protecting against pneumonia induced by S. aureus, and it worked synergistically with the antibiotic cefoxitin, suggesting its potential as a treatment for S. aureus infections.*

The resistance of () to various antibiotics has increased dramatically due to the misuse of antibiotics, and thus the development of new anti-infective drugs with new targets is urgently needed to combat resistance. Caseinolytic peptidase P is a case in hydrolase that regulates the virulence level of . Here, we found that nepetin, a small-molecule compound from traditional Chinese herbal flavonoids, effectively inhibits ClpP activity.

The strategy of targeting virulence factor has received great attention as it barely develops bacterial resistance. Sortase A (SrtA) and caseinolytic peptidase P (ClpP), as important virulence factors, are considered to be ideal pharmacological targets for methicillin-resistant Staphylococcus aureus (MRSA) infection. Through screening hundreds of compounds, we found scutellarin, a natural flavonoid, markedly inhibited SrtA and ClpP activities of MRSA strain USA300 with an IC of 53.
