Bulk RNA-seq of myocardial tissue from an LLC tumor-bearing Foxp3-DTR-GFP mouse in the diphtheria toxin-induced Treg-depleted group. Approximately 50 mg of myocardial tissue was used for total RNA extraction; library type: bulk RNA-seq; biological replicate 3 Treatment: LLC tumor-bearing Foxp3-DTR-GFP mouse with diphtheria toxin-induced transient Treg depletion; no immune checkpoint inhibitor. Poly(A)+ mRNA was enriched using Oligo(dT) magnetic beads, libraries were prepared for paired-end bulk RNA sequencing.
