BACKGROUND: To date, mitochondrial genomes of more than one hundred flatworms (Platyhelminthes) have been sequenced. They show a high degree of similarity and a strong taxonomic bias towards parasitic lineages. The mitochondrial gene atp8 has not been confidently annotated in any flatworm sequenced to date. However, sampling of free-living flatworm lineages is incomplete. We addressed this by sequencing the mitochondrial genomes of the two small-bodied (about 1 mm in length) free-living flatworms Stenostomum sthenum and Macrostomum lignano as the first representatives of the earliest branching flatworm taxa Catenulida and Macrostomorpha respectively...

Osteosarcoma is the most frequent type of malignant primary bone tumor. Although many efforts have been made, the survival rate of osteosarcoma still remains  unsatisfied. Long non-coding RNAs (lncRNAs) have been demonstrated to be associated with many diseases including tumors, and involved in the regulation of a wide array of pathophysiological processes. Colon-cancer-associated transcript-1 (CCAT1) was first identified in colon cancer and has subsequently been reported to perform many functions in tumor progression...

Approximately half of the world's 500,000 new oesophageal squamous-cell carcinoma (ESCC) cases each year occur in China. Here, we show whole-genome sequencing of DNA and RNA in 94 Chinese individuals with ESCC. We identify six mutational signatures (E1-E6), and Signature E4 is unique in ESCC linked to alcohol intake and genetic variants in alcohol-metabolizing enzymes. We discover significantly recurrent mutations in 20 protein-coding genes, 4 long non-coding RNAs and 10 untranslational regions. Functional analyses show six genes that have recurrent copy-number variants in three squamous-cell carcinomas (oesophageal, head and neck and lung) significantly promote cancer cell proliferation, migration and invasion...

BACKGROUND: Nearly 30% of clear cell renal cell carcinoma (ccRCC) patients present with metastasis at the time of diagnosis, and the prognosis for these patients is poor. Therefore, novel potential prognostic biomarkers and therapeutic targets for ccRCC could be helpful. Emerging evidence indicates that lncRNAs play important roles in cancer tumorigenesis and could be used as potential biomarkers or therapeutic targets. PANDAR (promoter of CDKN1A antisense DNA damage activated RNA) is a relatively novel lncRNA that plays an important role in the development of multiple cancers...

Long non-coding RNAs (lncRNAs) have emerged as new gene regulators and prognostic markers in various cancers. Although the lncRNA nuclear enriched abundant transcript 1 (NEAT1) has been associated with tumorigenesis, its functions in renal cell carcinoma (RCC) have not been elucidated. We determined that NEAT1 is up-regulated in RCC tissue compared to corresponding non-tumor tissue. High NEAT1 expression was associated with tumor progression and poor survival in RCC patients. NEAT1 knockdown suppressed RCC cell proliferation by inhibiting cell cycle progression, and inhibited RCC cell migration and invasion by reversing the epithelial-to- mesenchymal transition phenotype...

Long non-coding RNA (lncRNA) H19 in tumors played important roles in various biological processes. However, the biological role and molecular mechanism of H19 in breast cancer are unclear. Here, we found that H19 was aberrantly upregulated in human breast tumor tissues and cells. A negative correlation between H19 and miR-152 and positive correlation between H19 and DNMT1 mRNA were observed. Downregulation of H19 and DNMT1 significantly retarded breast cancer cell proliferation and invasion. H19 act as an endogenous sponge by directly binding to miR-152...
