Multi-omics analysis revealing a senescence-relevant lncRNAs signature for the assessment of response to immunotherapy for breast cancer.

ABSTRACT: Breast cancer (BRCA) is the most fatal malignancy of women. Immunotherapy has greatly improved the prognosis of advanced BRCA. Cellular senescence contributes to tumorigenesis and suppresses anti-cancer immunity. Identification of senescence-relevant long noncoding RNAs (SRlncRNAs) signature may benefit the predictions of prognosis and response to immunotherapy of BRCA. RNA-seq, mutation, and clinical data of BRCA were acquired from public databases. SRlncRNAs were screened using univariate Cox regression analysis. Consensus clustering classified BRCA patients into 2 clusters, and the differences of overall survival (OS) and immune status between the 2 clusters were analyzed by survival analysis, CIBERSORT, and ESITIMATE. The SRlncRNAs signature was constructed by least absolute shrinkage
