HOX antisense intergenic RNA (HOTAIR), a long non-coding RNA, plays an important role in the development of many types of cancers. Its function in acute leukemia (AL), however, has not been examined. The present study investigated the role of HOTAIR and its downstream genes in AL, and determined whether it could act as a molecular marker for prediction of leukemia development and prognosis. Real-time quantitative PCR was used to examine the expression of each gene in the HOTAIR signaling pathway in AL patients. The relationship between expression of HOTAIR and downstream genes and AL prognosis was analyzed. Expression of HOTAIR in patients with acute monocytic leukemia (M5) was increased as compared to controls (P<0.05). Compared to patients with low HOTAIR expression, overall survival and event-free survival of patients with high HOTAIR expression was significantly reduced. In addition, the expression of downstream genes in the HOTAIR signaling pathway including EZH2, LSD1, DNMT3A and DNMT3B was significantly increased in AL patients, and showed a significant positive correlation with high expression of HOTAIR (P<0.05). In conclusion, HOTAIR was closely related with a poor prognosis in AL patients. It may be involved in the development of leukemia by mediating methylation of DNA and histones.

Multi-drug resistance-associated protein 1 (MRP1) plays critical roles in the multi-drug resistance (MDR) of cancer cells, LncRNA HOTAIR is closely related to MDR in lung cancer, however, the effects of HOTAIR on MRP1 expression and MDR in lung cancer cells (A549/DDP) remain unknown. In this study, the effects of HOTAIR on MRP1 gene expression and MDR in A549/DDP cells were monitored. LncRNA HOTAIR was upregulated in A549/DDP cells, and overexpression of HOTAIR promoted MRP1 expression and MDR development.

Objective To investigate the effect of serum containing Xinfeng capsule (XFC) on the angiogenesis of human umbilical vein endothelial cells (HUVEC) induced by rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS) and its mechanism of action. Methods An in vitro co-culture model of RA-FLS and HUVEC was established. Serum containing XFC was prepared by oral gavage of SD rats.

Gastrointestinal (GI) cancers, such as gastric cancer, hepatocellular carcinoma, colorectal cancer, and esophageal cancer, pose a significant medical and economic burden globally, accounting for the majority of new cancer cases and deaths each year. A lack of knowledge about the molecular mechanisms of GI cancers is reflected in the low efficacy of treatment for individuals with late stage and recurring illness. Understanding the molecular pathways that promote the growth of GI cancers may open doors for their therapy.

Homeobox (HOX) transcript antisense RNA (HOTAIR) and HOX genes are reported to be more expressed in various cancers in humans in recent studies. The role of HOTAIR and HOXD genes in acute myeloid leukemia (AML) and chronic myeloid leukemia (CML) is not well known. In this study, expression levels of HOXD8, HOXD9 and HOXD11 from HOXD gene family and HOTAIR were determined from peripheral blood samples of 30 AML and 30 CML patients and 20 healthy volunteers by quantitative Real Time PCR.
