Mycotoxins are contaminants commonly found in foods and represent a worldwide threat to human health and welfare. Efforts have been undertaken to reduce mycotoxins and their toxicity, including the introduction of good agricultural practices, appropriate food processing, specific biotransformation approaches, and pursue therapeutic agents to counteract mycotoxins. Efficient and predictive tools are required for investigations on mycotoxins and their toxicodynamics, and strategies for mycotoxin reduction. Gene expression and transcriptome analysis can unravel the mode of action, transformation and combined toxicity of mycotoxins, or mycotoxin's interactions with food components including dietary therapeutics, at the cellular level and from a molecular perspective. MicroRNAs (miRNAs) regulate endogenously and posttranscriptionally the expression of target genes and enzymes involved in physiological, disease and toxicological responses, and the metabolism of therapeutic agents. Accordingly, this review aimed to collect up-to-date information on (1) the regulatory role of miRNAs in mycotoxin-initiated toxicological processes and (2) the protective role of active ingredients from plants on mycotoxin-induced toxicity. Through such a review of published evidence, we found some common signal pathways involving miRNAs shared by these two types of biological events. This finding indicates the possibility of using miRNAs as biomarkers in assessing and controlling mycotoxins in food via cellular mechanisms.

Astaxanthin (ASX), "king of carotenoids", is a xanthophyll carotenoid that is characterized by a distinct reddish-orange hue, procured from diverse sources including plants, microalgae, fungi, yeast, and lichens. It exhibits potent antioxidant and anti-ageing properties and has been demonstrated to mitigate ultraviolet-induced cellular and DNA damage, enhance immune system function, and improve cardiovascular diseases. Despite its broad utilization across nutraceutical, cosmetic, aquaculture, and pharmaceutical sectors, the large-scale production and application of ASX are constrained by the limited availability of natural sources, low production yields and stringent production requirements.

Background: Bone marrow inflammaging is a low-grade chronic inflammation that induces bone marrow aging. Multiple age-related and inflammatory diseases involve bone marrow inflammaging. Whether common pathological pathways exist in bone marrow inflammaging remains unclear.

The enzyme 12-lipoxygenase (12-LOX) catalyzes the formation of pro-inflammatory eicosanoids and is known to promote the migration of macrophages, yet its role in obesity-associated inflammation remains incompletely understood. Furthermore, differences between mouse and human orthologs of 12-LOX have limited efforts to study existing pharmacologic inhibitors of 12-LOX.

Numerous studies have shown that hyperlipidaemia is closely related to the gut microbiota, and the study of microbiota in the treatment of hyperlipidaemia is undoubtedly a new target for the treatment and prevention of hyperlipidaemia. The efficacy of regulating the gut microecology and changing the structure of gut flora has been demonstrated by both western and traditional medication, biological therapy, and dietary exercise, so it is particularly important to study the relationship between gut microbiota and the treatment of hyperlipidaemia. In this review, we summarize the mechanism and relationship between the pathogenesis of hyperlipidaemia and gut microbiota, and the mechanism of hyperlipidaemia treatment by influencing the gut microbiota in various treatment modalities, which provides diversified therapeutic ideas and scientific basis for clinical treatment.
