Summary: The study showed that MSMEG_1954 in M. smegmatis has a similar function to confer macrolide resistance as Rv3197 in Mycobacterium tuberculosis. Crystal structures revealed at least two different conformations of MSMEG_1954, with a closed state and an open state due to conformational changes in the N-terminal accessory domain. The degradation of the N terminal accessory domain in MSMSG_1954-form 2 represents a transitional state between the closed state and the open state, facilitating the binding of ADP and subsequent opening of the antibiotic binding pocket.

Summary: The study revealed that ATP-binding cassette transporters (ABCs) play important roles in cyantraniliprole resistance. Inhibition of ABCs increased the toxicity of cyantraniliprole, while overexpression of ABCs in fruit flies enhanced their tolerance to cyantraniliprole. Suppression of specific ABC transporters increased the sensitivity of cyantraniliprole-resistant strains. These findings provide valuable insights for resistance management strategies.

Summary: In this study, we investigated the correlation between genes involved in the biosynthesis of secondary metabolites in Rosmarinus officinalis using proteomics and metabolomics data by WGCNA, and identified three modules with the highest potential for metabolite engineering. Moreover, we identified hub genes highly connected to specific modules, transcription factors, protein kinases, and transporters. The results indicated that genes such as CDS, PAL, CIN, RAS, TAT, C4H, and MYB58 are responsible for biosynthesis of important secondary metabolites.

Summary: This study evaluated the responses of cyanobacteria and eukaryotic microalgae to a mixture of antibiotics. The results showed that the antibiotics selectively stimulated the growth and photosynthetic activity of cyanobacteria, without disrupting the co-existing eukaryotic microalgae. The antibiotic exposure also led to an increase in the proportion of cyanobacteria and a decrease in the proportion of eukaryotic microalgae in the mixed-culture system, which may contribute to the formation of cyanobacterial blooms.

Summary: The oriental armyworm Mythimna separata is a polyphagous corn pest in Asia. Transgenic Bt corn can effectively control this insect pest. This study identified 43 ABC transporter genes in the M. separata genome, and found that MsABCC2 may play a more important role in Cry1Ac toxicity and is a potential Cry1Ac receptor in M. separata. These findings provide valuable information for understanding the role of ABC transporter genes in M. separata and the long-term application of Bt insecticidal protein.

Summary: One of the main reasons for the ineffectiveness of chemotherapy in breast cancer is the development of multidrug resistance phenotype in tumour cells caused by the expression of ABC transporters. This study found that abnormalities in certain ABC transporter genes and changes in gene expression levels are closely associated with the effectiveness of breast cancer treatment and can serve as potential prognostic markers for therapeutic outcomes and metastatic survival.

Summary: Recent studies have shown that triclosan (TCS) exposure can inhibit photosynthesis, reduce pigments, and induce oxidative stress in algae, leading to growth inhibition and morphological alterations. However, the underlying molecular mechanisms of TCS toxicity at environmentally relevant concentrations were unclear. This study used transcriptomic analysis to uncover the molecular mechanisms of TCS toxicity in Raphidocelis subcapitata. The results showed that TCS suppressed molecular signaling pathways related to porphyrin and chlorophyll metabolism, photosynthesis - antenna proteins, and photosynthesis, with the inhibition becoming more pronounced at higher TCS concentrations. Additionally, replication-coupled DNA repair signaling was activated only at the highest TCS concentration. These findings indicate that photosynthesis systems are sensitive targets of TCS toxicity in R. subcapitata, which is different from the inhibition of lipid synthesis observed in bacteria.

Summary: This study investigates the chronic toxicity and intergenerational effects of zinc oxide nanoparticles (ZnO NPs) on the freshwater invertebrate Daphnia magna through transcriptomic analysis. The exposure of parent daphnia to ZnO NPs resulted in inhibited reproduction and growth, accompanied by downregulation of genes involved in lysosomal and phagosome, energy metabolism, and endocrine disruption pathways. Partial recovery of growth and reproductive inhibition was observed in subsequent generations, suggesting limited transgenerational effects.

Summary: Benzo[a]pyrene (BaP), a common environmental pollutant, can induce bone toxicity in unexposed offspring. This study found that exposure of medaka to BaP resulted in reduced bone thickness in subsequent generations, and dysregulation of various molecular pathways involved in bone formation and bone resorption. Additionally, epigenetic factors were also implicated in the transgenerational effects of BaP on bone health. These findings highlight the importance of further research on the mechanisms and potential biomarkers of BaP-induced bone disease.

Summary: Periphyton in aquatic ecosystems, comprising prokaryotes and eukaryotes, play a crucial role in element cycling. This study used DNA metabarcoding to investigate the distribution characteristics of epilithic periphyton in the Jue River and its tributaries in China. The results showed that water quality variables, such as salinity, water temperature, and nitrogen concentrations, increased with decreasing elevation. Additionally, salinity, nutrients, and total dissolved solids were identified as crucial variables shaping periphyton community structure. The photosynthetic efficiency of periphyton declined at high altitudes due to lower chlorophyte abundance.

Summary: The e-waste recycling activities in China have led to the discharge of polychlorinated biphenyls (PCBs) into soil and aquatic environments, causing environmental pollution and ecological risks. The pollution levels were significantly higher in both the traditional and emerging recycling areas compared to their respective upstream countryside areas. The source analysis revealed that PCBs mainly originated from technical mixtures manufactured in Japan and the USA. The downstream areas, including the coastal area, were also affected by formal and informal recycling activities through river runoff, leading to adverse ecotoxicological consequences for humans and aquatic organisms.

Summary: This study investigates the potential toxic mechanism of cisplatin, a cytotoxic drug, on a model water flea. The results reveal that exposure to cisplatin significantly reduces the offspring number, delays pregnancy, and decreases body length in Daphnia magna. Transcriptome analysis shows that differentially expressed genes are primarily enriched in digestion and absorption, nerve conduction, endocrine interference, and circulatory related pathways. The down-regulation of digestive secretion and nutrient absorption may impede energy supply, hinder growth and reproduction, and affect ovarian development and cell growth. In addition, the reduced expression of genes in cardiomyocyte contraction and apoptosome processes may contribute to the death of Daphnia magna.

Summary: Concerns have been raised about the ecotoxicological effects of active pharmaceutical ingredients (APIs) on aquatic invertebrates in the last decade. This study conducted a thorough literature review to summarize the ecotoxicological data of APIs tested on various invertebrates. Different therapeutic classes of APIs showed varying levels of toxicity to crustaceans, and the sensitivity towards exposure differed between species. The study also highlighted the need for further research on the multigenerational effects and toxic mechanisms of APIs on freshwater crustaceans' endocrine systems.
