Effects of SOCS2-AS1 inhibition in prostate cancer cells

Project description:Prostate cancer is the most common cancer in men and AR downstream signalings promote prostate cancer cell proliferation. We identified a novel androgen-regulated long non-coding (lnc) RNA, SOCS2-AS1. In order to investigate the SOCS2-AS1 function in prostate cancer cells, we performed gene expression in AR-positive prostate cancer cell lines (LNCaP and LTAD) after siSOCS2-AS1 or siSOCS2 treatment. We also treated cells with vehicle or androgen to analyzed the effects of siSOCS2-AS1 on AR function. Observation of androgen dependent gene expression changes after treatmet with siSOCS2-AS1 with microarray.

TM4SF1-AS1 inhibits apoptosis by promoting stress granule formation in cancer cells

Project description:Long noncoding RNAs (lncRNAs) play pivotal roles in tumor development, but little is known about their involvement in the early steps of tumorigenesis. To identify lncRNAs dysregulated in precancerous lesions, we analyzed genome-wide trimethylation of histone H3 lysine 4 (H3K4me3) to screen for transcriptionally active lncRNA genes in the nontumorous gastric mucosa of patients with gastric cancer (GC) and healthy individuals. We found that H3K4me3 at TM4SF1-AS1 is specifically upregulated in GC patients and that expression of TM4SF1-AS1 is prevalently elevated in primary and cultured GC cells. TM4SF1-AS1 contributes to GC cell proliferation in vitro and in vivo, and its oncogenic function is mediated, at least in part, through interaction with Pur-α and YB-1. Chromatin isolation by RNA purification (ChIRP)-mass spectrometry demonstrated that TM4SF1‑AS1 associates with several stress granule (SG)-related proteins, including G3BP2, RACK1 and DDX3. Notably, TM4SF1-AS1 promotes SG formation and inhibits apoptosis in GC cells by sequestering RACK1, an activator of the stress-responsive MAPK pathway, within SGs. TM4SF1‑AS1-induced SG formation and apoptosis inhibition are dependent on Pur-α and YB-1. These findings suggest TM4SF1-AS1 contributes to tumorigenesis by enhancing SG-mediated stress adaptation.

SOCS2 expression correlates with tumor malignancy, exerts growth promoting effects and is enhanced by androgens in prostate cancer

Project description:Deregulation of cytokine- and growth factor signaling due to altered expression of endogenous regulators is well recognized in prostate and other cancers. Suppressor of cytokine signaling 2 (SOCS2) is a key regulator of growth hormone, IGF and prolactin signaling, that have been implicated in carcinogenesis. In this study we elucidate expression pattern and functional significance of SOCS2 in prostate cancer (PCa). Protein expression analysis employing tissue microarrays from two independent patient cohorts revealed significantly enhanced expression in tumor compared to benign tissue as well as association with Gleason score and disease progression. In vitro and in vivo assays uncovered the involvement of SOCS2 in the regulation of cell growth and apoptosis. Functionally, SOCS2 knockdown inhibited prostate cancer cell proliferation and xenograft growth in a CAM assay. Decreased cell growth after SOCS2 downregulation was associated with cell-cycle arrest and apoptosis. In addition, we prove for the first time that SOCS2 expression is significantly elevated upon androgenic stimulation in androgen receptor-positive cell lines, providing a possible mechanistic explanation for high SOCS2 levels in PCa tissue. Consequently, SOCS2 expression correlated with androgen receptor expression in malignant tissue of patients. Taken together, our study linked increased SOCS2 expression in PCa with a pro-proliferative role in vitro and in vivo. Prostate cancer cell lines LNCaP, DUCaP and VCaP cells were cultured in the absence or presence of R1881, an androgen in three independent experiments. Differential gene expression was determined by comparing R1881 treated samples with the corresponding controls (EtOH treated samples).

Androgen-induced Long Noncoding RNA (lncRNA) SOCS2-AS1 Promotes Cell Growth and Inhibits Apoptosis in Prostate Cancer Cells.

Project description:Long noncoding RNAs (lncRNA) have been associated with the development of cancer. However, the interplay between lncRNAs and androgen receptor (AR) signaling in prostate cancer is still unclear. Here, we identified lncRNAs induced by androgen in AR-positive prostate cancer cells, where induction was abolished by AR knockdown as well as an anti-androgen, bicalutamide. By combining these data, we identified an androgen-regulated lncRNA, suppressor of cytokine signaling 2-antisense transcript 1 (SOCS2-AS1), the expression of which was higher in castration-resistant prostate cancer model cells, i.e long-term androgen-deprived (LTAD) cells, than in parental androgen-dependent LNCaP cells. SOCS2-AS1 promoted castration-resistant and androgen-dependent cell growth. We found that SOCS2-AS1 knockdown up-regulated genes related to the apoptosis pathway, including tumor necrosis factor superfamily 10 (TNFSF10), and sensitized prostate cancer cells to docetaxel treatment. Moreover, we also demonstrated that SOCS2-AS1 promotes androgen signaling by modulating the epigenetic control for AR target genes including TNFSF10 These findings suggest that SOCS2-AS1 plays an important role in the development of castration-resistant prostate cancer by repressing apoptosis.

LncRNA HIF1A-AS1 regulates the apoptosis and proliferation of vascular endothelial cells through globally regulating miRNAs expression [RNA-Seq]

Project description:In the current study, on the basis of establishment of PA-induced damage model of HUVECs, the silencing and overexpression (OE) of HIF1A-AS1 were implemented in the HUVECs, and the effects on cell viability, apoptosis, migration and invasion were explored, respectively. Functionally, the results indicated silencing of HIF1A-AS1 promoted the proliferation migration and invasion, and reduced the apoptosis of HUVECs. In contrast, OE of HIF1A-AS1 reduced proliferation transwell and invasion, promoted the apoptosis, suggesting that HIF1A-AS1 play vital roles in regulating HUVECs. Moreover, miRNA sequencing (miRNA-seq) and RNA sequencing (RNA-seq) were carried out, and the results indicated that HIF1A-AS1 globally mediate expression of miRNA and mRNA. The multiple target genes of DEmiRNA were associated with cell proliferation and apoptosis, and overlapped with the DEGs from RNA-seq, suggestion that HIF1A-AS1 might regulate the proliferation and apoptosis of HUVECs by regulating miRNA expression.
