The role of transforming growth factor-β(TGF-β)induced epithelial-mesenchymal transition(EMT)in cancer cell dissemination is well established,but the involvement of IncRNAs in TGF-p signaling is still *** this study,we observed that the IncRNAActivated by TGF-β(IncRNA-ATB)was upregulated in hepatocellular carcinoma(HCC)metastases and associated with poor ***-ATB upregulated ZEB1 and ZEB2 by competitively binding the miR-200 family and then induced EMT and *** addition,IncRNA-ATB promoted organ colonization of disseminated tumor cells by binding IL11 mRNA,inducing autocrine of IL11 and triggering STAT3 ***,IncRNA-ATB promotes the invasion-metastasis ***,these findings suggest that IncRNA-ATB,a mediator of TGF-βsignaling,could predispose HCC patients to metastases and may serve as a potential target for anti-metastatic therapies.

Background:Aberrant DNA methylation plays a significant role in tumorigenesis which can be induced by folate deficiency of diet in colorectal cancer(CRC).Some DNA methylation alterations can be reflected in cell-free circulating DNA(circDNA),making circDNA an ideal noninvasive biomarker for cancer diagnosis and ***,what DNA methylation alterations is induced by folate deficiency exactly and whether these alterations is a valid noninvasive circulating biomarker for CRC are still ***:To gain specific insight into aberrant DNA methylation induced by folate deficiency and role of these alterations in clinical outcome of ***:The DNA methylation patterns of the normal human colon mucosal epithelial cell line(NCM460),cultured in a normal or low folate level,were mapped by NimbleGen Methylated DNA Immunoprecipitation(MeDIP)assay and the hypermethylation in the promoter of cystathionine-beta-synthase(CBS)were ***,the hypermethylation of CBS promoter and the inhibition of CBS expression were further confirmed in vitro and vivo by bisulfate sequencing PCR(BSP),real-time RT-PCR and ***,the hypermethylation of CBS in circDNA of patients'plasma were also detected and statistically correlated with pathological parameters and clinical outcome of ***:The methylation of CBS promoter in NCM460 cultured with the low folate level was improved but the expression of CBS in NCM460 cultured with the low folate level was *** methylation level of CBS promoter in tumor tissues was higher than normal controls and the expression level in tumor tissues was lower than normal *** addition,the methylation level of CBS promoter in tumor tissues and plasma circDNA samples from patients with the high plasma folate level was also improved *** analysis showed the hypermethylation of CBS in circDNA correlated with pathological stage,recurrence and overall *** analysis indicated t

Long noncoding RNA(IncRNA)H19 is the first imprinted IncRNA to be defined.H19 has been implicated in the development of the liver,as H19 is the most differentially expressed IncRNA in liver development according to our previous microarray results;however,the function of H19 and its underlying mechanism of action are largely *** this study,we found that H19 was overexpressed in fetal liver tissues and that H19inhibited the proliferation of fetal liver *** also found that this effect was independent on well-known miR-675 axis and that hnRNP U may be involved in this *** demonstrated that Mus musculus H19 blocked the interaction between heterogeneous nuclear ribonucleoprotein U(hnRNP U)and actin in fetal liver cells,which can lead to transcriptional *** determine the target genes that may be affected by hnRNP U and H19,we performed chromatin immunoprecipitation coupled with high-throughput sequencing(ChlP-seq)with an anti-hnRNP U *** ChlP-seq results indicated that genes involved in the Wnt signaling pathway were significantly enriched in hnRNP U-binding *** knockdown and overexpression of H19 in fetal liver cells revealed that H19 restrained the activity of the Wnt signaling *** results also revealed that H19 negatively regulated the expression of Frequently rearranged in advanced T cell lymphomas(Fratl),which is a positive regulator of Wnt signaling *** together,our results suggest that H19 represses the proliferation of fetal liver cells and activity of Wnt signaling pathway,and hnRNP U may play an important role in it
