Myocardial ischemia/reperfusion injury (MI/R) is one of the most prominent topics of contemporary research. The frequent failure of potential therapeutic drugs and interventions to transfer to clinical practice demonstrates the limitations in using experimental animal models. Because a variety of transgenic animals are readily available in mice, researchers in recent years have made use of murine models rather than of larger animal models for experimental MI/R. This review focuses on in vivo and ex vivo murine models of MI/R and aims to characterize the source of our mechanistic understanding in mice. A systematic review of the literature demonstrated that there is great diversity among ex vivo (Langendorff) and in vivo models of MI/R.

Phenylketonuria is a genetic disorder characterized by high phenylalanine levels, the main toxic metabolite of the disease. Hyperphenylalaninemia can cause neurological impairment. In order to avoid this symptomatology, patients typically follow a phenylalanine-free diet supplemented with a synthetic formula that provides essential amino acids, including L-carnitine.

Introduction/objectives: Sjogren's syndrome (SS) is a chronic inflammatory and difficult-to-treat autoimmune disease. Timosaponin AIII (TAIII), a plant-derived steroidal saponin, effectively inhibits cell proliferation, induces apoptosis, and exhibits anti-inflammatory properties. This study explored the mechanisms of action of TAIII in SS treatment by studying gut microbiota and short-chain fatty acids (SCFAs) using fecal metabolomics.

Emerging evidence highlights the significance of peripheral inflammation in the pathogenesis of Parkinson's disease (PD) and suggests the gut as a viable therapeutic target. This study aimed to explore the neuroprotective effects of the probiotic formulation VSL#3 and its underlying mechanism in a PD mouse model induced by MPTP. Following MPTP administration, the striatal levels of dopamine and its metabolites, as along with the survival rate of dopaminergic neurons in the substantia nigra, were significantly reduced in PD mice.

Cells are subjected to dynamic mechanical environments which impart forces and induce cellular responses. In age-related conditions like pulmonary fibrosis, there is both an increase in tissue stiffness and an accumulation of senescent cells. While senescent cells produce a senescence-associated secretory phenotype (SASP), the impact of physical stimuli on both cellular senescence and the SASP is not well understood.

Fluorescent biosensors offer a powerful tool for tracking and quantifying protein activity in living systems with high temporospatial resolution. However, the expression of genetically encoded fluorescent proteins can interfere with endogenous signaling pathways, potentially leading to developmental and physiological abnormalities. The EKAREV-NLS mouse model, which carries a FRET-based biosensor for monitoring extracellular signal-regulated kinase (ERK) activity, has been widely utilized both in vivo and in vitro across various cell types and organs.
