TASL and neoplasm: Based on this, this study was conducted to explore the correlation between TASL and tumor prognosis, immune infiltration, and immunotherapy in 33 cancer types using databases such as the Cancer Genome Atlas (TCGA) dataset, the Genotype-Tissue Expression (GTEx) dataset as well as the Gene Expression Omnibus (GEO) dataset, to provide ideas for further research on the prognostic and therapeutic potential of TASL.
