CircESR1 and HNRNPAB function in estrogen receptor positive (ER+) breast cancer [RNA-Seq]
Ontology highlight
ABSTRACT: Breast cancer (BC) is the most prevailing type of cancer among women in the world. ERα protein, which is transcribed and translated by estrogen receptor gene ESR1, is one of the marker molecules for clinical classification of BC. However, whether circRNAs specifically expressed in hormone receptor-positive BC play a role which is independent of ERα (estrogen receptor alpha) protein activity and signaling pathways is unknown. Whether these circRNAs could impinge on the sensitivity of ER+ BC cells to the endocrine therapy and targeted drug therapy is also unexplored.By screening circRNAs involved in estrogen receptor (ER) signaling, circESR1 was identified as a circRNA exhibiting high specificity of expression in ER+ breast cancer. Our studies elucidate a novel signaling complex centering around circESR1 and HNRNPAB in ER+ breast cancer and suggest that circESR1 might represent a potential therapeutic target for this disease.
