Project description:Through integrative analysis of clinical breast cancer gene expression datasets, cell line models of breast cancer progression, and mutation data from cancer genome resequencing studies, we have identified RNA binding motif protein 47 (RBM47) as a candidate suppressor of breast cancer metastasis. RBM47 inhibited breast cancer progression in experimental models. Transcriptome-wide analysis of RBM47 localization by HITS-CLIP revealed widespread binding to mRNAs, preferentially at the 3' UTRs. RBM47 altered the abundance of a subset of its target mRNAs. Some of the mRNAs stabilized by RBM47, as exemplified by dickkopf WNT signaling pathway inhibitor 1 (DKK1), mediate tumor suppressive effects downstream of RBM47. This work identifies RBM47 as a suppressor of breast cancer progression and highlights the potential of global RNA modulatory events as a source of metastasis-promoting phenotypic traits. Cancer cells transduced with doxycycline-inducible wildtype RBM47 or the RBM47-I281fs mutant, treated with increasing concentrations of doxycycline.

Project description:We identified RNA binding motif protein 47 (RBM47) as a target gene of transforming growth factor (TGF)-beta in mammary gland epithelial cells (NMuMG cells) that have undergone the epithelial-to-mesenchymal transition (EMT). TGF-beta repressed RBM47 expression in NMuMG cells and lung cancer cell lines. Expression of RBM47 correlated with good prognosis in patients with lung, breast, and gastric cancer. RBM47 suppressed the expression of cell metabolism-related genes, which were the direct targets of nuclear factor erythroid 2-related factor 2 (Nrf2; also known as NFE2L2). RBM47 bound to KEAP1 and Cullin3 mRNAs, and knockdown of RBM47 inhibited their protein expression, which led to enhanced binding of Nrf2 to target genomic regions. Knockdown of RBM47 also enhanced the expression of some Nrf2 activators, p21/CDKN1A and MafK induced by TGF-beta. Both mitochondrial respiration rates and the side population cells in lung cancer cells increased in the absence of RBM47. Our findings, together with the enhanced tumor formation and metastasis of xenografted mice by knockdown of the RBM47 expression, suggested tumor suppressive roles for RBM47 through the inhibition of Nrf2 activity. Effect of shRNA for RBM47 and TGF-beta on gene expression was evaluated by RNA-seq and RBM47-bound RNAs were identified by RIP-seq in A549 cells.

Project description:Long non-coding RNAs have been implicated in many of the hallmarks of cancer. We previously annotated lncRNA152 (lnc152; a.k.a. DRAIC) and demonstrated its roles in proliferation, cell cycle progression, and regulation of the estrogen signaling pathway in breast cancer cells. Herein, we found that lnc152 is highly upregulated in luminal breast cancers, but is downregulated in triple-negative breast cancers (TNBC). Using a set of complementary experimental approaches, we found that knockdown of lnc152 promotes cell migration and invasion in luminal breast cancer cell lines. In contrast, ectopic expression of lnc152 inhibits growth, migration, invasion, and angiogenesis in TNBC cell lines. In xenograft studies in mice, lnc152 inhibited the growth and metastasis of TNBC cells. Transcriptome analysis of the xenografts indicated that lnc152 downregulates genes regulating cancer-related phenotypes, including angiogenesis. Using RNA-pull down assays coupled with LC-MS/MS analysis, we identified RBM47, a known tumor suppressor protein in breast cancer, as a lnc152-interacting protein. We found that lnc152 suppresses the aggressive phenotypes of TNBC cells by regulating the expression of RBM47. Collectively, our results demonstrate that lnc152 is an angiogenesis-inhibiting tumor suppressor that attenuates the aggressive cancer-related phenotypes found in TNBC.
