miRNA profiling of pooled serum circulating cell-free miRNA of Tn+ tumor-bearing mice
Listed in NCBI GEO
To investigate the systemic impact of Tn+ tumor phenotypes, we conducted an analysis of circulating miRNAs in the serum of mice bearing Tn+- 4T1 tumors.
Description
The 4T1/Tn+ cell line was generated via CRISPR/Cas9 targeting of Cosmc, and tumors were established orthotopically in BALB/c mice. Tumor-bearing animals were monitored for primary growth and micrometastatic dissemination to the lungs, followed by serum collection at endpoint.
Serum samples were pooled according to tumor Tn status (Tn+ or Tn–) for total RNA extraction, including small RNAs. Using the NanoString nCounter Mouse v1.5 miRNA assay, we profiled miRNA expression in three serum pools (two Tn+, one Tn–), followed by normalization and quality control via the nCounter Advanced Analysis Software. Expression values were normalized using geometric means of internal positive and negative controls, and only stable miRNA regions (CV < 15%) were retained for downstream analysis.
