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.

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.

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.

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.

OBJECTIVE:
To investigate the role of long-chain non-coding RNA MALAT1 in modulating paclitaxel resistance in breast cancer cells.
METHODS:
Breast cancer SK-BR-3 cells were treated with gradient concentrations of paclitaxel to induce paclitaxel resistance of the cells. The resistant cells were transfected with si-NC, si-MALAT1, pcDNA, pcDNA-MALAT1, miRNC, miR-485-3p mimics, si-MALAT1+anti-miR-NC, or si-MALAT1+anti-miR-485-3p liposomes. Following the transfections, the cells were examined for changes in IC of paclitaxel using MTT assay; the protein expression of P-gp, Bcl-2 and Bax were detected with Western blotting, and a dual luciferase reporter assay was used to detect the binding of MALAT1 to miR-485-3p.
RESULTS:
Compared with paclitaxel-sensitive SK-BR-3 cells, paclitaxel-resistant SK-BR-3 cells showed significantly increased the IC of paclitaxel with up-regulated MALAT1 expression and down-regulated miR-485-3p expression ( < 0.05). Silencing MALAT1 or overexpressing miR-485-3p obviously lowered the IC of paclitaxel and the expression of P-gp and Bcl-2 and increased the expression of Bax in SK-BR-3/PR cells ( < 0.05). miR-485-3p was identified as the target of MALAT1, and inhibiting miR-485-3p significantly reverse the effect of MALAT1 silencing on IC of paclitaxel and the expressions of P-gp, Bcl-2 and Bax in SK-BR-3/PR cells ( < 0.05).
CONCLUSIONS
MALAT1 can modulate paclitaxel resistance in breast cancer cells possibly by targeting miR-485-3p to down-regulate P-gp and Bcl-2 and up-regulate Bax.

Metastases account for the overwhelming majority of cancer-associated deaths. The dissemination of cancer cells from the primary tumor to distant organs involves a complex process known as the invasion-metastasis cascade. The underlying biological mechanisms of metastasis, however, remain largely elusive. Recently, the discovery and characterization of non-coding RNAs (ncRNAs) have revealed the diversity of their regulatory roles, especially as key contributors throughout the metastatic cascade. Here, we review recent progress in how three major types of ncRNAs (microRNAs, long non-coding RNAs, and circular RNAs) are involved in the multistep procedure of metastasis. We further examine interactions among the three ncRNAs as well as current progress in their regulatory mechanisms. We also propose the prevention of metastasis in the early stages of cancer progression and discuss current translational studies using ncRNAs as targets for metastasis diagnosis and treatments. These studies provide insights into developing more effective strategies to target metastatic relapse.
