With the development of genome-wide sequencing technology, 195 types of functional, long non-coding RNAs (lncRNAs) have been identified so far, and their cellular roles are gradually being revealed. LncRNAs have now become a hotspot in the field of life sciences. These small molecules exist in almost all higher eukaryotes and play very important regulatory roles in these organisms. This review briefly summarizes the recent progress in research on plasmacytoma variant translocation 1 gene (PVT1), an lncRNA.

Increasing evidence suggests that long non-coding RNAs (lncRNAs) are of vital importance for various biological processes, and dysregulation of lncRNAs is frequently associated with various diseases such as psoriasis. LncRNAs modulate gene expression at the transcriptional, post-transcriptional, and translational levels; however, the specific regulatory mechanisms of lncRNAs in psoriasis remain largely unexplored. This review provides an overview of recent studies investigating mechanisms and functions of lncRNAs in psoriasis, especially focusing on the role of lncRNAs in keratinocytes, T cells, and dendritic cells.

Recent studies have demonstrated the importance of the non-protein coding part of human genome in carcinogenesis and metastasis of prostate cancer. Long non-coding RNAs (lncRNAs) play a key regulatory role in prostate cancer biology. LncRNAs are dysregulated in prostate cancer and the expression levels of certain lncRNAs are associated with the recurrence, metastasis and prognosis of cancer. It is also proved that lncRNAs, as oncogenes, can promote carcinogenesis and development of prostate cancer. This review focuses on the progress in the studies of lncRNAs in prostate cancer.

Long noncoding RNAs are a group of noncoding RNAs with a length more than 200 nucleotides. Recent studies have revealed that long noncoding RNAs play an important role in the development and progression of cancer. Lung cancer is the leading cause of cancer-related death all over the world. In this article, we review the roles of long noncoding RNAs in lung cancer to provide new insights into the diagnosis and treatment of the disease.

Long non-coding RNA (LncRNA) is defined as a class of transcripts more than 200 nucleotides in length and without the protein-coding function. It has been found for years, however, that little is known about the potential role of LncRNA in humans. But recent studies showed that LncRNA can regulate the coding-gene expression and participate in effects of human body. Accumulating evidence demonstrated that LncRNA are involved in cancer incidence, development and progression.With further exploration on the mechanisms of tumors, the relationship between the long non-coding RNA and hematological malignancies increasingly become a hot research. This review focuses on the mechanisms of LncRNA in hematological malignancies.

OBJECTIVETo predict orthologous sequences of the GENCODE-identified 13 562 human long non-coding RNAs (lncRNA) in 16 mammalian genomes and construct a lncRNA database LongMan for lncRNA studies.

METHODSThe exon structures of a total of 13 562 human lncRNAs were analyzed using RNAfold, and their orthologous sequences were searched against 16 mammalian genomes using Infernal. The potential orthologous genes, transposons and splicing signals of human lncRNAs were predicted to construct a lncRNA database with a updating mechanism.

RESULTSand

CONCLUSIONThe lncRNA database LongMan we constructed, which currently contains 133 646 orthologous lncRNAs, provides information of the sequences, alignments, transposons, and species-specific insertions and deletions and allows database search on combinatorial conditions, graphic display and data download. As the first large-scale mammalian orthologous lncRNA database, LongMan has important values in future comparative and functional studies of lncRNAs.
