Several studies have shown that long non-coding RNAs (lncRNAs) may play anessential role in Epithelial-mesenchymal transition (EMT), which is an important step in tumor metastasis, however, little is known about the global change of lncRNA transcriptome during EMT. To investigate how lncRNA transcriptome alteration contributes to EMT progression regulation, we performed a whole-transcriptome strand-specific RNA deep sequencing of MCF10A induced EMT by TGF-ß. Deep sequencing results showed that the long RNA (>=200-nt) transcriptome of MCF10A was undergone a global changed in EMT, and this alteration was determined as early as 8h after being induced using TGF-ß. 8703 linear novel genes with ambiguous protein-coding potential were identified, 512 of which were further determined to be novel lncRNAs. After analyzing the expression of 5473 known and novel lncRNAs, as well as 2208 known and novel circRNAs during EMT, we found a large numbers of lncRNAs might be involved in the regulation of EMT. Intriguingly, we identified 216 gene clusters constituted by lncRNAs and/ornovel genes in “gene desert” region. The expressions of all genes in these clusters were changed concurrently during EMT, indicating that these clusters might play important role in EMT. Our study reveals a global reprogramming of lncRNAs transcriptome in EMT and provides clues to the study of the molecular mechanism of EMT.

View SamplesThe transcriptome sequencing reveals the divergence of the genetic mechanism of reproductive traits in two Chinese native breeds. XH chicken was meat-type breed with low reproduction ability, with a 70~80% incidence of broodiness in population, with the duration of 15~30 d brooding, and with a production of 60~90 eggs per year. BEH chicken was layer-type breed with high reproduction ability, with a 10%~15% incidence of broodiness in population, with the duration of 7~20 d brooding, and with a production of 180 eggs per year.

View SamplesAs an ancient winning strategy of microorganisms, glucose repression mechanism has become specialized to perfection in Saccharomyces cerevisiae. The galactose (GAL) metabolism network is stringently regulated by glucose repression in yeast and has been a classic system for studying gene regulation. We show here that the population of S. cerevisiae living in fermented milks has autonomously reinstated an ancient version of the structural GAL genes through introgression. The introgressed GAL network has completely abolished the glucose repression and conversed from a strictly inducible to a constitutive system through coordinative polygenic changes in the regulatory components of the network, including transitions in the upstream repressing sequence site of GAL4 that impair Mig1p-mediated repression and loss of function of the inducer Gal3p and the repressor Gal80p. In addition, the introgressed GAL2 gene has been duplicated while the native HXT6 and HXT7 genes have been inactivated, resulting in galactose-over-glucose preference and elevated galactose utilization rate. Relying on the reverse evolution of the GAL network, the non-lactose fermenting yeast has become a dominant species co-existing with other lactose fermenting microorganisms in fermented milks. Our results also provide new clues for developing yeast strains devoid of barriers to co-utilization of different sugars.

View SamplesSingle cell RNA-seq was applied for studying the transcriptomic profile in early zebrafish PGCs(primordial germ cells) by choosing three time points during zebrafish embryonic development. The three time points were 6hpf(hours post fertilization, also called shield stage), 11hpf(also called 3-somite stage) and 24hpf(also called prim-5 stage).
