Hence, ferroptosis may play an important role in spermatogenesis dysfunction in case of cryptorchidism. Therefore, the purpose of this study was to identify the key ferroptosis-related genes that influence spermatogenesis in patients with cryptorchidism and provided new strategies for the prevention and treatment of spermatogenesis dysfunction in cryptorchidism patients in clinical practice. <b>Methods:</b> Gene expression information was downloaded from the Gene Expression Omnibus (GEO) and ArrayExpress databases.

Anoikis, a type of programmed cell death, serves as a barrier against the dissemination of cancer cells to distant organs, thereby constraining the progression of cancer. Nevertheless, the mechanism of genes related to anoikis in HCC is yet to be elucidated.MethodsThis paper's data (TCGA-HCC) were retrieved from the database of the Cancer Genome Atlas (TCGA). Differential gene expression with prognostic implications for anoikis was identified by performing both the univariate Cox and differential expression analyses. Through unsupervised cluster analysis, we clustered the samples according to these DEGs.
