Plants synthesize a diverse array of flavonoids that endow them with the ability to adapt to a wide range of natural environments. For humans, flavonoids have been used for centuries for their dietary health benefits and therapeutic applications. As a result, research into the biosynthesis, regulation, and metabolic engineering of flavonoids has received increasing attention. In this review, we present the latest advances in this field, with a particular focus on species-specific flavonoid biosynthetic pathways and newly discovered transcriptional regulatory mechanisms. Furthermore, we provide an overview of valuable flavonoids that have been synthesized successfully using metabolic engineering. The development of purple tomatoes is highlighted as a case study, demonstrating the potential to translate plant research into marketable high-flavonoid products.

Impaired muscle regrowth in aging is underpinned by reduced pro-inflammatory macrophage function and subsequently impaired muscle cellular remodeling. Macrophage phenotype is metabolically controlled through TCA intermediate accumulation and activation of HIF1A. We hypothesized that transient hypoxia following disuse in old mice would enhance macrophage metabolic inflammatory function thereby improving muscle cellular remodeling and recovery.

Marine-derived enzymes often show distinct physiological properties and great potential for industrial use. Salt ions may improve the stability and expression efficiency of marine enzymes, which requires salt-resistant host based expression platform. Aspergillus oryzae of good protein expression and secretion was evaluated and explored for this purpose.

Introduction: Knockout of the Fmo5 gene in mice led to a lean, slow-ageing phenotype characterised by the presence of 2,3-butanediol isomers in their urine and plasma. Oral treatment of wildtype mice with 2,3-butanediol led to a low cholesterol, low epididymal fat phenotype.
Objectives: Determine if significant, heterozygous coding variations in human FMO5 would give rise to similar clinical and metabolic phenotypes in humans, as in C57BL/6J mice with knockout of the Fmo5 gene and in particular, increased excretion of 2,3-butanediol.

Immune checkpoint inhibitors (ICIs) have revolutionized cancer therapy but are increasingly linked to immune-related kidney injury (irKI). This study presents the first bibliometric analysis of irKI research (2000-2025), aiming to identify key trends, mechanistic insights, and pharmacological risk factors. We analyzed 2,179 publications to understand the evolution of irKI research, focusing on areas like T cell-mediated tubular injury, immune system-driven inflammation, and changes in metabolism.

Purpose: To investigate the role of personal risk factors in the occurrence of the vascular, neurological and fibroproliferative disorders of the hand-arm vibration syndrome (HAVS) in workers groups exposed to hand-transmitted vibration (HTV).
Methods: HAVS prevalence and incidence data were pooled across a series of cross-sectional studies (total sample: 1272 HTV workers, 579 controls) and prospective cohort studies (total sample: 377 HTV workers, 138 controls) conducted in Central and North-Eastern Italy. The pooled studies included detailed individual-level information about HTV exposure, personal risk factors, medical comorbidities and HAVS disorders.
