Background: Cataracts are one of the most prevalent blinding eye diseases globally, and ferroptosis may be involved in its pathogenesis; however, the precise mechanisms remain unclear. We therefore aimed to identify ferroptosis-related genes (FRGs) related to cataracts and assess their causal association.
Methods: We downloaded two gene expression profile datasets of patients with cataracts and gathered the FRGs from the MSigDB and GeneCards databases. This allowed us to find the ferroptosis-related differentially expressed genes (FRDEGs). The potential functions of these FRDEGs were explored using Kyoto Encyclopedia of Genes and Genomes (KEGG), gene ontology (GO), and gene set enrichment analysis (GSEA). A protein-protein interaction (PPI) network was established, and hub genes were screened. Additionally, potential diagnostic markers were identified by RT-PCR validation. Finally, a Mendelian randomization (MR) study was performed to ascertain the causal impact of FRDEGs on cataracts.
Results: Nineteen FRDEGs were identified by overlapping DEGs with FRGs. GO, KEGG and GSEA showed that the FRDEGs were associated with oxidative stress, IL17 signaling pathway, and glutathione metabolism. Nine hub genes were identified using the PPI network and five algorithms in Cytoscape. The RT-PCR results validated TIGAR, IL6, ATF3, and TNFAIP3 as potential biomarkers.
Conclusion: TIGAR and IL6 were identified to be causally associated with cataracts. Inverse variance weighting revealed that TIGAR decreased the risk of cataracts, whereas IL6 increased the risk of cataract. Our research identified ferroptosis-related hub genes in cataracts, providing valuable insights for pre-symptomatic diagnosis and contributing to our understanding of the molecular mechanisms of cataract risk genes.

Background: Burn injuries trigger complex immune responses and gene expression changes, impacting wound healing and systemic inflammation. Understanding these changes is crucial for identifying biomarkers and therapeutic targets.
Methods: We analyzed two GEO datasets (wound tissue (GSE8056) and blood (GSE37069)) to identify differentially expressed genes (DEGs) in burn injury samples versus controls.

Osteoporosis is a progressive bone disease characterized by reduced bone density and deterioration of bone microarchitecture, predominantly affecting the elderly population. The ongoing COVID-19 pandemic has introduced additional challenges in osteoporosis management, potentially due to systemic inflammation and direct viral impacts on bone metabolism. This study aims to identify common differentially expressed genes (DEGs) and key molecular pathways shared between osteoporosis and COVID-19, with the goal of uncovering potential therapeutic targets through bioinformatics analysis.

Background: Ischemic stroke (IS), the leading stroke subtype (∼87%), arises from vascular occlusions, triggering brain necrosis through ischemia-reperfusion injury. Ferroptosis, an iron-driven cell death via Fe-mediated lipid peroxidation, is implicated in IS pathology. This study demonstrates that enoyl-coA hydrolase 1 (ECH1) may serve as a peripheral biomarker and therapeutic target for IS based on ferroptosis signaling.

Background: Acute and long-term mental health disorders correlate with coronavirus disease 2019 (COVID-19). The underlying mechanisms responsible for the coexistence of COVID-19 and depression remain unclear, and more research is needed to find hub genes and effective therapies. The main objective of this study was to evaluate gene-expression profiles and, identify key genes, and discovery potential therapeutic agents for co-occurrence in COVID-19 and major depressive disorder (MDD).

Background: Colorectal cancer (CRC) is common and deadly, often leading to metastasis, challenging treatment, and poor outcomes. Understanding its molecular basis is crucial for developing effective therapies.
Aims: This study aimed to investigate the role of Myosin Heavy Chain 11 (MYH11) in CRC progression, especially its effects on epithelial-mesenchymal transition (EMT) and cell behavior, and to explore its potential regulation by the EMT transcription factor zinc finger E-box binding homeobox 1 (ZEB1).
