Despite this progress, clinical translation is limited by variability in sampling, lack of standardized protocols, and insufficient large-scale validation. This review synthesizes recent developments in human salivary metabolomics, emphasizing disease-specific biomarkers and key applications in systemic disease diagnosis and monitoring. We also examine methodological and biological factors that influence data reliability, including collection methods, storage conditions, circadian rhythms, age, and host–microbiome interactions. Furthermore, integration of multiomics strategies, machine learning, and clinical registry data is discussed as a means to enhance biomarker discovery and translational potential.

Exome sequencing identified rare variants in unrelated FMD (<i>N</i> = 93) and SMD (<i>N</i> = 287) patients. Gene Burden Analysis (GBA) was performed, and candidate genes were prioritized using the number of variant carriers, inner-ear expression, and hearing/balance-related phenotypic annotations. FMD patients showed higher accumulation of missense and loss-of-function variants than SMD, especially in genes linked to auditory and vestibular function. GBA identified 269 enriched genes in SMD, with 31 annotated for inner ear phenotypes, while FMD had 432 with 51 pinpointed. Sporadic and FMD overlapped in 28.1% of enriched genes, with <i>ADGRV1</i>, <i>MEGF8</i>, and <i>MYO7A</i> most commonly shared. Auditory brainstem responses from knockout mouse models supported hearing loss of three novel MD candidate genes (<i>NIN</i>, <i>CCDC88C</i>, and <i>ANKRD24</i>), consistent with patient hearing profiles.

While they may cause damages to cells and threaten human health, they play essential roles in cellular signaling toward mitochondrial and immune homeostasis. Overproduction or insufficient supply of free radicals can both lead to health concerns and disease syndromes by causing oxidative or reductive stress to cells. Current redox therapies frequently fail clinically due to imprecise dosing and targeting, causing therapeutic futility or paradoxical harm by disrupting redox homeostasis, necessitating integrated frameworks linking redox biology to precision interventions alongside therapeutic innovation. This review explores free radicals’ generation sources, characterizes mitochondrial oxidative phosphorylation and pathological hyperglycemia as pivotal endogenous sources, and proposes oxygen and transition metals as fundamental regulators. This paper synthesizes multidimensional molecular mechanisms and pathologies arising from redox dysregulation and establishes reductive stress as a critical pathogenesis driver alongside oxidative stress.

Reduced PKP2 expression was detected in both HF rat and mouse. Subsequent in vivo studies on <i>Pkp2-</i>knockout (<i>Pkp2</i>-KO) rats demonstrated that adeno-associated virus serotype 9 (AAV9)-mediated restoration of PKP2 not only restored cardiac PKP2 expression but also attenuated the progression of fibrosis.

Single-cell RNA sequencing analysis in rats revealed enriched pathological profibrotic cardiac fibroblasts (CFs) in PKP2-deficient myocardium.

Their conserved seven-transmembrane (7TM) structure enables these signaling networks by allowing interactions with multiple ligands and intracellular effectors. In several types of tumors, abnormal GPCR signaling promotes carcinogenesis by supporting immune evasion, cell proliferation, and therapeutic resistance. A significant research gap exists in fully understanding the molecular mechanisms behind pathway-specific activation and biased ligand discovery of GPCRs, which could lead to the development of more effective therapies.
