Aging is a gradual process during the loss of functions in cells,organs and tissues by time. The molecular mechanisms of aging-related theories include the classical ones such as telomere,oxygen radical and nonenzymatic glycosylation,as well as the newly proposed ones such as DNA methylation,mitochondrial DNA （mtDNA）and autophagy. The latest study showed the anti-aging effect of autophagy in hematopoietic stem cells. In recent years,based on the molecular regulative mechanisms of aging,a number of the promising anti-aging drugs have been found,including nicotinamide mononucleotide（NMN）and FOXO4-DRI,a peptide of anti-aging. In addition,there are many new discoveries in the field of plant extracts,in which,the extracts from Chinese herbal medicine（CHM）,some single CHMs and the classical prescriptions of CHM,represented by curcumin and resveratrol,have the partial anti-aging effects by regulating the molecular mechanisms of aging both in vivo and in vitro. In brief,developing or exploring anti-aging drugs,especially the natural drugs,is one of the main development directions in the field of anti-aging research in the basis of the molecular regulative mechanisms of aging.

Background: Bioinformatics analysis of hepatocellular carcinoma (HCC) expression profiles can aid in understanding its molecular mechanisms and identifying new targets for diagnosis and treatment.
Aim: In this study, we analyzed expression profile datasets and miRNA expression profiles related to HCC from the GEO using R software to detect differentially expressed genes (DEGs) and differentially expressed miRNAs (DEmiRs).
Methods And Results: Common DEGs were identified, and a PPI network was constructed using the STRING database and Cytoscape software to identify hub genes.

Indole-3-propionic acid (IPA), a metabolite produced by gut microbiota through tryptophan metabolism, has recently been identified as playing a pivotal role in bone metabolism. IPA promotes osteoblast differentiation by upregulating mitochondrial transcription factor A (Tfam), contributing to increased bone density and supporting bone repair. Simultaneously, it inhibits the formation and activity of osteoclasts, reducing bone resorption, possibly through modulation of the nuclear factor-κB (NF-κB) pathway and downregulation of osteoclast-associated factors, thereby maintaining bone structural integrity.

Attention-deficit/hyperactivity disorder (ADHD) is a common psychiatric condition among children and adolescents, often associated with a high risk of psychiatric comorbidities. Currently, ADHD diagnosis relies exclusively on clinical presentation and patient history, underscoring the need for clinically relevant, reliable, and objective biomarkers. Such biomarkers may enable earlier diagnosis and lead to improved treatment outcomes.

Metabolism is the name given to all of the chemical reactions in the cell involving thousands of proteins, including enzymes, receptors, and transporters. Inborn errors of metabolism (IEM) are caused by defects in the production and breakdown of proteins, fats, and carbohydrates. Micro ribonucleic acids (miRNAs) are short non-coding RNA molecules, ⁓19-25 nucleotides long, hairpin-shaped, produced from DNA.
