Project description:Estrogens(E2) are important steroid hormones that regulate differentiation, proliferation, and apoptosis in hormone-dependent breast cancer.In order to detect the E2-dependent transcription program associated with the observed cell cycle response, we analyzed the effect of H2ac knockdown on MCF-7 gene expression using microarray. Interestingly, we noticed that 51% of the E2-upregulated genes are down-regulated by depletion of H2ac. The data also show that H2ac regulated E2-dependent genes through E2-induction signaling pathway. MCF-7 cell line was transfected with scrambled or H2ac siRNA in the absence or persence of E2.
Project description:In previous study, we found circFAT1(e2) was highly expressed in breast cancer tissues and cell lines. And this factor is also a crucial role in breast cancer genesis and development. So in this study, we knocked down circFAT1(e2) in MCF-7 cells. The viability and metastasis was significantly inhibited with circFAT1(e2) depletion. In order to explore the potential down-stream gene of circFAT1(e2) in breast cancer cells. We extracted the total RNA from circFAT1(e2) knockdown MCF-7 cells and negative control group by using TriZol reagent. Then, toal RNA was subjected to transcriptome sequencing to determine the potential down-stream targets of circFAT1(e2). We expect to reveal the underlied mechanism of the regulatory effect on breast cancer of circFAT1(e2).
