The mussel Mytilus coruscus is an important and very popular seafood in China and widespread along the eastern coast of China. In this study, we investigated the molecular response of mussel gonads to cadmium accumulation at two concentrations (80 and 200 µg/L) for 30 days using ionomics and proteomics techniques. The shrinkage of the cells and mod...

... As(III) is especially effective in this context. This interaction culminates in the suppression of key pathways such as the pyruvate oxidation pathway and the tricarboxylic acid cycle, compromised gluconeogenesis, and diminished oxidative phosphorylation (Meng et al. 2023). Additionally, As can react with the cofactor S-adenosylmethionine (SAM) in a process facilitated by AS methyltransferase (AS3MT) in mammals. ...
Current research studies on arsenic in the plant and soil system reveal that arsenic toxicity to plant species is strongly influenced by many factors including its nature (organic or inorganic), speciation (i.e. As (V); arsenite, arsenate, As (III)), solubility, concentration, the type of plant species, and other soil variables affecting arsenic bioaccumulation in plants. Therefore, As (V) or As (III) toxicity, uptake, and detoxification vary among plant species. Herein, the origins and spread of As pollution and As speciation in soil are briefly examined. Further, the numerous physiological and molecular mechanisms contributing to As(V) and As(III) toxicity, absorption, and detoxification processes in plants are investigated in detail. The role of several enzymatic (glutathione reductase, ascorbate peroxidase superoxide dismutase, and catalase) and non-enzymatic (phosphorus, phytochelatins, proline, glutathione, salicylic acid, and nitric oxide) substances under As (V/III) stress have been explained using a theoretical framework that illustrates the toxicity and translocation pathways of this metalloid in plants. This review focuses on two main topics: (i) the role of different molecules in modifying As-induced toxicities in plants and (ii) the role of nanoparticles in reducing As stress in plants. Significant research gaps that need to be addressed in order to improve our scientific knowledge of As in soil-plant systems are also highlighted.

Cadmium also causes immunosuppression (Chen et al., 2021;Xie et al., 2019) and impairs reproduction being able to alter development (Wu et al., 2017;Simoniello et al., 2013), gonadal function (Bhardwaj et al., 2021;Meng et al., 2023) and endocrine pathways (Motta et al., 2021;Qu et al., 2022). ...
Over a reproductive cycle, the prevalence and intensity of degeneration of testicular follicles in Megapitaria squalida collected from the mining port of Santa Rosalia (a highly metal-polluted area), and San Lucas (a less polluted site), Gulf of California, Mexico, were evaluated. At San Lucas, most individuals had a typical testicular
structure; degeneration of testicular follicles was present in 9.5 % of spawning organisms. In contrast, at Santa Rosalia, 68 % of males, mainly in the ripe stage, had testicular degeneration (72 % severe intensity, mostly in medium and large-sized). Degeneration was characterized by intense hemocyte infiltration, identified as dense
masses with numerous melanized cells in the follicle lumen. In both sites, males with testicular follicle degeneration had a lower condition index compared to males without degeneration. Degeneration of testicular follicles before spawning compromises and decreases the reproductive activity of M. squalida males at Santa
Rosalia, which may ultimately affect the population's sustainability.
