lncRNA GAS5 and the efficacy of steroids

lncRNA

Glucocorticoids (GCs) are widely employed in inflammatory, autoimmune and neoplastic diseases, and, despite the introduction of novel therapies, remain the first-line treatment for inducing remission in inflammatory bowel disease (IBD). Given the high incidence of suboptimal response, associated with a significant number of side effects, that are particularly severe in paediatric patients, the identification of subjects that are most likely ...

Identification and validation long non-coding RNAs of oral squamous cell carcinoma by bioinformatics method

lncRNA

Gene markers of oral squamous cell carcinoma (OSCC) have great significance on early diagnosis and treatment of clinical oral cancer. In this study, researchers from the Children Hospital of Chongqing Medical University used RNA-Seq data from OSCC patients and filtered differentially-expressed long non-coding RNA (lncRNA) to further clarify the molecular mechanism. First, they downloaded datasets of OSCC from National Center ...

Detection of long non-coding RNAs in human breastmilk extracellular vesicles

lncRNA

Breastmilk has many documented beneficial effects on the developing human infant, but the components of breastmilk that influence these developmental pathways have not been fully elucidated. Increasing evidence suggests that non-coding RNAs encapsulated in extracellular vesicles (EVs) represent an important mechanism of communication between the mother and child. Long non-coding RNAs (lncRNAs) are of particular interest given their key role ...

Long non-coding RNAs – novel prognostic biomarkers for liver metastases in patients with early stage colorectal cancer

lncRNA

Liver metastasis is the primary cause of death for colorectal cancer (CRC) patients. To investigate the prognostic value of long non-coding RNAs (lncRNAs) on colorectal liver metastases, quantitative reverse-transcriptase PCR (quantitative RT-PCR) was performed on 15 lncRNAs in 51 stage IV CRC with liver metastases and 57 stage I/II CRC specimens. The expression levels of four lncRNAs (GAS5, H19, MEG3 ...

lncRNA GAS5 is a critical regulator of metastasis phenotype of melanoma cells

lncRNA

The present study intended to demonstrate the effects of long noncoding RNA growth arrest-specific transcript 5 (GAS5) on the migration and invasion of melanoma cells. Researchers at Kunming Medical University first detected the expression of GAS5 among four kinds of melanoma cell lines, followed by constructing GAS5-knocked down and overexpressed stable cells. Next, they evaluated the effects of GAS5 on ...

Investigation of Circulating LncRNAs in B-cell Neoplasms

Long non-coding RNAs (lncRNA) which are longer than 200 base pairs in length, play important role in the cellular machinery. Chronic lymphocytic leukemia (CLL) and multiple myeloma (MM) are neoplasms of B-cells. Researchers at Istanbul University aimed to investigate circulating lncRNA levels of CLL and MM patients. For this purpose they selected 5 candidate lncRNAs (TUG1, LincRNA-p21, MALAT1, HOTAIR, and ...

A critical role for the long non-coding RNA GAS5 in proliferation and apoptosis in non-small-cell lung cancer

lncRNA

In recent years, long non-coding RNAs (lncRNAs) have been investigated as a new class of regulators of cellular processes, such as cell growth, apoptosis, and carcinogenesis. Although lncRNAs are dysregulated in numerous cancer types, limited data are available on the expression profile and functional role of lncRNAs in non-small cell lung cancer (NSCLC). In the present study, researchers at the ...

Regulation of lncRNA expression by miRNA

lncRNA

In addition to protein-coding genes, the human genome makes a large amount of noncoding RNAs, including microRNAs and long noncoding RNAs (lncRNAs). Both microRNAs and lncRNAs have been shown to have a critical role in the regulation of cellular processes such as cell growth and apoptosis, as well as cancer progression and metastasis. Although it is well known that microRNAs ...

Long non-coding RNA GAS5 regulates apoptosis in prostate cancer cell lines

While the role of small non-coding RNAs, such as miRNAs, in apoptosis control is well established, long non-coding RNAs (lncRNAs) have received less attention. Growth Arrest-Specific 5 (GAS5) encodes multiple snoRNAs within its introns, whilst exonic sequences produce lncRNA which can act as a riborepressor of the glucocorticoid and related receptors. GAS5 negatively regulates the survival of lymphoid and breast ...

Long Non-coding RNA GAS5 Functions as a Tumor Suppressor in Renal Cell Carcinoma

Renal cell carcinoma (RCC) is a malignancy with a poor prognosis. Researchers at the Medical College of Soochow University, China  aimed to explore whether the expression of Long Non-Coding RNA (LncRNA) growth arrest-specific transcript 5 (GAS5) is associated with RCC genesis. They selected twelve clinical samples diagnosed for renal clear cell carcinoma and found that the LncRNA GAS5 transcript levels ...
