Microbial Pathogenesis

Spring viremia of carp virus (SVCV) is a lethal freshwater pathogen of cyprinid fish that has caused significant economic losses to aquaculture. To reduce the economic losses caused by SVCV, its pathogenic mechanism needs to be studied more thoroughly. Here, we report for the first time that SVCV infection of Epithelioma papulosum cyprini (EPC) cells can induce cellular autophagy and apoptosis through endoplasmic reticulum stress. The presence of autophagic vesicles in infected EPC cells was shown by transmission electron microscopy. Quantitative fluorescence PCR and Western blot results showed that p62 mRNA expression was decreased, and the expression of Beclin1 and LC3 mRNA was increased. The p62 protein was decreased, and the Beclin1 protein and LC3 were increased in the endoplasmic reticulum stress activation state. To further clarify the mode of death of SVCV-infected EPC cells, we examined caspase3, caspase9, BCL-2, and Bax mRNA, which showed that they were all increased. Apoptosis of SVCV-infected cells increased upon activation of endoplasmic reticulum stress. Our results suggest that endoplasmic reticulum stress can regulate SVCV infection-induced autophagy and apoptosis. The results of this study provide theoretical data for the pathogenesis of SVCV and lay the foundation for future drug development and vaccine construction.

Environmental Geochemistry and Health

Wastewater-based epidemiology (WBE) is an objective approach for the estimation of population-level exposure to a wide range of substances, in which the use of a population biomarker (PB) could significantly reduce back-calculation errors. Although some endogenous or exogenous compounds such as cotinine and other hormones have been developed as PBs, more PBs still need to be identified and evaluated. This study aimed to propose a novel method to estimate population parameters from the mass load of metal ion biomarkers in wastewater, and estimate the consumption of tobacco in 24 cities in Southern China using the developed method. Daily wastewater samples were collected from 234 wastewater treatment plants (WWTPs) in 24 cities in Southern China. Atomic absorption spectroscopy (AAS) was applied to determine the concentrations of common health-related metal ions in wastewater, including sodium (Na), potassium (K), magnesium (Mg), calcium (Ca), iron (Fe), and zinc (Zn), and compared them with the daily mass load of cotinine corresponding to catchment populations. The concentrations of cotinine in wastewater samples were measured using liquid chromatography-tandem mass spectrometry. There were clear and strong correlations between the target metal ion equivalent population and census data. The correlation coefficients (R) were RK = 0.78, RNa = 0.66, RCa = 0.81, RMg = 0.77, and RFe = 0.69, at p < 0.01 and R² > 0.6. Subsequently, the combination of WBE and metal ion PBs was used to estimate tobacco consumption. Daily consumption of nicotine was estimated to be approximately 1.76 ± 1.19 mg/d/capita, equivalent to an average of 13.0 ± 8.75 cigarettes/d being consumed by smokers. The data on tobacco consumption in this study were consistent with those in traditional surveys in Southern China. The metal ion potassium is an appropriate PB for reflecting the real-time population and could be used to evaluate the tobacco consumption in WBE study.

... Spring viremia carp virus is one of the important viral pathogens in warm water species. This virus was shown to induce ER stress (elevated GRP78, BECLIN1, and LC3II/LC3I protein expression), autophagy, apoptosis (flow cytometry), and also protein processing pathways in the ER [162]. Autophagy, endocytosis, phagosome, and protein processing in ER were also enriched in coelomocytes of sea urchins challenged with Vibrio anguillarum baths [163]. ...

... For example, autophagy and antigen processing may be involved in minimizing the number of infectious particles in the cell (6)(7)(8)(9). On the other hand, other fish rhabdoviruses may manipulate autophagy to evade immunity, promote replication and facilitate their release from infected cells (10)(11)(12). Transmission electron microscopy (TEM) has allowed visualization of defense mechanisms in VHSV-exposed RBCs related to the elimination of viral proteins and antigen presentation, which is the formation of vesicles similar to autophagosomes (7). The adaptive immune response of fish RBCs involves the expression of major histocompatibility complex (MHC) class I and II molecules (7,13). ...

... By analyzing the biomarkers of drug residues in domestic sewage, the daily mass loads of illicit drugs entering a wastewater treatment plant (WWTP) could be calculated, which can offer valuable insights into temporal trends of drug consumption, free from any self-report bias [7][8][9] or ethical concerns [10,11]. Since the application of WBE in illicit drugs analysis was first introduced in 2001 [12] and applied in 2005 [13], using WBE to monitor the use of drugs has been practiced in multiple countries and regions [14][15][16][17][18][19][20]. In addition to the documented quantitative analysis of targeted illegal drugs in sewage utilizing triple quadrupole mass spectrometry, a suspect screening strategy for illicit drug investigation using WBE and high-resolution mass spectrometry (HRMS) has been suggested [21][22][23][24]. ...

... Among all techniques, mass spectrometry is a powerful technique for the analysis of peptide and protein therapeutics. Hyphenated LC-MS can characterise peptides and associated impurities since it has an excellent combination of robustness, high-resolution power, and speed of analysis (Pan et al. 2011;Han et al. 2021;Molineau et al. 2022). Application of soft ionization techniques such as electrospray ionization (ESI) and matrixassisted laser desorption ionization (MALDI) can identify intact molecular mass of peptides or peptide-mass fingerprinting generated upon enzymatic digestion while tandem mass spectrometry (MS/MS) can provide information even in amino acid sequence (Thiede et al. 2005;Duncan and Gibson 2012). ...
