High-throughput sequencing identified differentially expressed RNAs between MALAT1 knockdown C3H10 adipocyte and control cells

ABSTRACT: Although MALAT1 is a lncRNA highly expressed in many tissues and participates in a series of physiological and pathological processes, the potential role of MALAT1 in adipogenesis is not clear. To gain full insights into MALAT1 function in the adipogenic differention of C3H10 cell, we performed RNA-seq to antisense oligonucleotides(ASO) treated C3H10 cells and found numerous differentially expressed RNAs between MALAT1 knockdown C3H10 adipocyte and control cells.

Differentiation of Mammary Tumors and Reduction in Metastasis Upon Malat1 LncRNA Loss

Project description:Genome-wide analyses have identified thousands of long non-coding RNAs (lncRNAs). Malat1 (Metastasis Associated Lung Adenocarcinoma Transcript 1) is among the most abundant lncRNAs whose expression is altered in numerous cancers. Here we report that genomic loss, as well as systemic knockdown of Malat1 using antisense oligonucleotides, in the MMTV-PyMT mouse mammary carcinoma model results in slower tumor growth accompanied by differentiation into highly cystic tumors and a significant reduction in lung metastasis. Further, Malat1 loss results in a reduction of branching morphogenesis in MMTV-PyMT and Her2/neu amplified tumor organoids consistent with the in vivo reduction in lung metastasis. At the molecular level, Malat1 knockdown results in alterations in gene expression and changes in splicing patterns of genes involved in differentiation and pro-tumorigenic signaling pathways. Together, these data indicate that the lncRNA Malat1 regulates critical processes in mammary cancer pathogenesis and represents a promising therapeutic target for inhibiting breast cancer metastasis. Transcriptome profiles of tumors and organoids after Malat1 knockdown using antisense olgonucleotides (ASOs).

Differential Gene expression in the mouse mammary tumors of PyMT-Malat1 wild-type (WT), PyMT-Malat1 knockout (KO) and PyMT-Malat1 knockout with Malat1 transgene expression (TG)

Project description:Previously, lncRNA Malat1 knockout mice were generated by insertional inactivation. By crossing this line to MMTV-PyMT mammary tumor mouse model, we produced PyMT;Malat1 wild-type (WT) and PyMT;Malat1 knockout (KO). Furthermore, we generated Malat1 transgenic mice by targeting ROSA26 locus and bred them to PyMT;Malat1 knockout mice to produce Malat1-rescued PyMT;Malat1 knockout;Malat1 transgenic animals (TG). Using mammary tumors from the three groups of animals, we performed RNA-Seq analysis to identify differentially up-regulated genes in KO tumors to find novel target genes of YAP-TEAD pathway.

RNA Decay in Processing Bodies is Indispensable for Adipogenesis

Project description:The RNA decay pathway plays key regulatory roles in cell identities and differentiation processes. Although adipogenesis is transcriptionally and epigenetically regulated and has been thoroughly investigated, how RNA metabolism that contributes to the stability of phenotype-shaping transcriptomes participates in differentiation remains elusive. In this study, we investigated Ddx6, an essential component of processing bodies (PBs) that executes RNA decay and translational repression in the cytoplasm and participates in the cellular transition of reprogramming. Upon adipogenic induction, Ddx6 dynamically accumulated to form PBs with a binding partner, 4E-T, at the early phase prior to emergence of intracellular lipid droplets. In contrast, preadipocytes with Ddx6 knockout (KO) or 4E-T knockdown (KD) failed to generate PBs, resulting in significant suppression of adipogenesis. Transcription factors related to preadipocytes and negative regulators of adipogenesis that were not expressed under adipogenic stimulation were maintained in Ddx6-KO and 4E-T-KD preadipocytes under adipogenic induction. Elimination of Dlk1, a major negative regulator of adipogenesis, in 3T3L1 Ddx6-KO cells did not restore adipogenic differentiation capacity to any extent. Similar to murine cells, human primary mesenchymal stem cells, which can differentiate into adipocytes upon stimulation with adipogenic cocktails, required DDX6 to maturate into adipocytes. Therefore, RNA decay of the entire parental transcriptome, rather than removal of a strong negative regulator, could be indispensable for adipogenesis.

Effects of the long noncoding RNA Malat1 on gene expression [Mouse430_2]

Project description:Malat1 is an abundant long noncoding RNA that localizes to nuclear bodies known as nuclear speckles, which contain a distinct set of pre-mRNA processing factors. Previous in vitro studies have demonstrated that Malat1 interacts with pre-mRNA splicing factors, including the serine- and arginine-rich (SR) family of proteins, and regulates a variety of biological processes, including cancer cell migration, synapse formation, cell cycle progression, and responses to serum stimulation. To address the physiological function of Malat1 in a living organism, we generated Malat1-KO (KO) mice using homologous recombination. Unexpectedly, the Malat1-KO mice were viable and fertile, showing no apparent phenotypes. Nuclear speckle markers were also correctly localized in cells that lacked Malat1. However, the cellular levels of another long noncoding RNA, Neat1, which is an architectural component of nuclear bodies known as paraspeckles, were downregulated in a particular set of tissues and cells lacking Malat1. To address if the the absence of Malat1 affects the expression of other genes, including other long noncoding RNA, microarrays were used to study the impact of knocking-out Malat1 on global gene expression in mouse embryonic fibroblasts (MEFs). MEFs were prepared from E13.5 mouse embryos from wildtype and Malat1 knock-out mice. RNA harvested from these cells were hybridized to Affymetirx mouse gene expression array.

Direct cell conversion from human dermal fibroblast to adipocyte

Project description:To investigate the effect of ZNF395 on adipogenesis, we tested whether ZNF395 enhance cell conversion from human dermal Fibroblast (FIB) to Adipocyte (ADP). PPARG2 was reported as a master regulator and can induce adipogenesis in non-adipogenic fibroblasts. We transduced PPARG2 with or without ZNF395 in FIB with lentivirus. Interestingly, co-transduction of PPARG2 and ZNF395 showed higher occurrence of adipocyte-like cells as compared with PPARG2 alone. Moreover, genes related with lipid metabolic process and lipid transport was significantly up-regulated in combination of PPARG2 and ZNF395. These results suggest that ZNF395 co-ordinate the transcriptional regulatory pathway with PPARG2, necessary for the induction of adipogenesis. Total RNA was obteined from human dermal fibroblast transduced with mock lentivirus vector (FIB_ctrl), PPARG2 (FIB_PPARG2) and co-transduced with PPARG2 and ZNF395 (FIB_PPARG2+ZNF395).
