Summary of "Long noncoding RNA MAPKAPK5-AS1 promotes colorectal cancer proliferation by partly silencing p21 expression."

Colorectal cancer (CRC) is the third most common malignant in the world, and long noncoding RNA (lncRNA) has become a new gene. Here, we report a novel lncRNA MAPKAPK5-AS1 which acts as a critical oncogene in the CRC. In addition, we attempted to explore the functions of MAPKAPK5-AS1 on tumor progression in vitro and in vivo. qRT-PCR was performed to examine the expression of MAPKAPK5-AS1 in CRC tissues and cells. MAPKAPK5-AS1 expression was significantly up-regulated in 50 colorectal cancer tissues and increased expression of MAPKAPK5-AS1 was found to be associated with greater tumor size and advanced pathological stages in CRC patients. Knockdown of MAPKAPK5-AS1 significantly inhibited proliferation and caused apoptosis in CRC cells. Then,we found that p21 is a target of MAPKAPK5-AS1. In addition, we first demonstrated that MAPKAPK5-AS1 plays a carcinogenic role in colorectal cancer. MAPKAPK5-AS1 is a novel prognostic biomarker and a potential therapeutic candidate for CRC cancer.

Long Noncoding RNA BCYRN1 Promotes the Proliferation of Colorectal Cancer Cells via Up-Regulating NPR3 Expression.

Long noncoding RNAs (lncRNAs) constitute a large proportion of noncoding transcripts that have recently emerged as a new class of important regulators in cancers. LncRNA BCYRN1, also known as BC200, h...

Overexpression of long non coding RNA CA3-AS1 suppresses proliferation, invasion and promotes apoptosis via miRNA-93/PTEN axis in colorectal cancer.

In previous studies, dysregulated lncRNAs in colorectal cancer were screened using RNA-sequencing by Atsushi Yamada. In these dysregulated lncRNAs, a long non coding RNA named CA3-AS1 attracted our at...

Long noncoding RNA HEIH promotes the proliferation and metastasis of non-small cell lung cancer.

This study is aimed to explore the functions of long noncoding RNA (lncRNA) HEIH on the proliferation as well as metastasis of non-small cell lung cancer (NSCLC).

Long noncoding RNA ABHD11-AS1 promote cells proliferation and invasion of colorectal cancer via regulating the miR-1254-WNT11 pathway.

The purpose of our study was to investigate the effects of the long noncoding RNA (lncRNA) ABHD11-AS1 on colorectal cancer (CRC) progression and further explore its possible underlying mechanisms. In ...

Downregulation of Long Noncoding RNA HOTAIR and EZH2 Induces Apoptosis and Inhibits Proliferation, Invasion, and Migration of Human Breast Cancer Cells.

The long noncoding RNA HOTAIR (HOX transcript antisense intergenic RNA) has been reported to be a biomarker for various malignant tumors; however, its involvement in breast cancer is not fully underst...

Medical and Biotech [MESH] Definitions

Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5. The mutation of these genes is associated with the formation of colorectal cancer (MCC stands for mutated in colorectal cancer).

Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.

Nuclear phosphoprotein encoded by the p53 gene (GENES, P53) whose normal function is to control CELL PROLIFERATION and APOPTOSIS. A mutant or absent p53 protein has been found in LEUKEMIA; OSTEOSARCOMA; LUNG CANCER; and COLORECTAL CANCER.

Tumor suppressor genes located in the 18q21-qter region of human chromosome 18. The absence of these genes is associated with the formation of colorectal cancer (DCC stands for deleted in colorectal cancer). The products of these genes show significant homology to neural cell adhesion molecules and other related cell surface glycoproteins.

A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.
