Description
Background: Estrogen receptor-positive (ER+) breast cancers represent approximately two-thirds of all breast cancers and have a sustained risk of late disease recurrence. Cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors have shown significant efficacy in ER+ breast cancer. However, their effects are still limited by drug resistance. In this study, we aim to explore the role of long noncoding RNA TROJAN in ER+ breast cancer. Methods: The expression level of TROJAN in breast cancer tissue and cell lines was determined by quantitative real-time PCR. In vitro and in vivo assays as well as patient derived organoids were preformed to explore the phenotype of TROJAN in ER+ breast cancer. The TROJAN-NKRF-CDK2 axis were screened and validated by RNA pull-down, mass spectrometry, RNA immunoprecipitation, microarray, dual-luciferase reporter and chromatin immunoprecipitation assays. Results: Herein, we showed that TROJAN was highly expressed in ER+ breast cancer. TROJAN promoted cell proliferation and resistance to a CDK4/6 inhibitor and was associated with poor survival in ER+ breast cancer. TROJAN can bind to NKRF and inhibit its interaction with RELA, upregulating the expression of CDK2. The inhibition of TROJAN abolished the activity of CDK2, reversing the resistance to CDK4/6 inhibitor. A TROJAN antisense oligonucleotide sensitized breast cancer cells and organoids to the CDK4/6 inhibitor palbociclib both in vitro and in vivo. Conclusions: TROJAN promotes ER+ breast cancer proliferation and is a potential target for reversing CDK4/6 inhibitor resistance.

Description
With stringent filtering criteria (fold change>2, p<0.001 and False Discovery Rate (FDR) <0.01), we identified 133 lncRNAs and 370 mRNAs that were the most highly differentially expressed. Of all the lncRNAs, 61 were upregulated, and 72 were downregulated.

Description
Although many protein-coding genes have been identified to be aberrantly expressed in gallbladder cancer, the mechanism that account for the development and progression of gallbladder cancer remains unclear. In recent years, long noncoding RNAs have been shown to play vital roles in mammalian cell biology. In this study, we found that a small number of lncRNAs that are aberrantly expressed.
