Summary
Breast cancer (BC) is a heterogeneous malignancy with distinct molecular subtypes and clinical characteristics. Tumor-initiating cells (TICs) constitute a small subset of cancer cells responsible for tumor initiation and progression. MicroRNAs (miRNAs), small non-coding RNA molecules, play a pivotal role in regulating gene expression and have been implicated in cancer development and progression. In this study, we conducted genome-wide CRISPR-Cas9 screens within 3D tumorspheres of two BC cell lines, MCF7 (ER+) and HCC1395 (TNBC). Our objective was to identify miRNAs that govern TIC viability, employing CRISPR/Cas9 pooled screens that targeted a total of 19,052 genes and 1,864 miRNAs. By suppressing relevant miRNAs following QuantSeq 3' mRNA sequencing we identify the genes regulated by those miRNAs
