The diagnostic/prognostic potential and molecular functions of long non-coding RNAs in the exosomes

lncrna

Cholangiocarcinoma (CCA) is an aggressive malignancy associated with unfavorable prognosis, and it’s difficult to diagnose and no effective treatments are available. Long non-coding RNAs (lncRNAs) play important roles in tumorigenesis and metastasis. Intact lncRNAs from exosomes have sparked much interest as potential biomarker for the non-invasive analysis of disease. Here, via exosome sequencing on lncRNAs, GO analysis, KEGG pathway and ...

Extracellular vesicle associated long non-coding RNAs functionally enhance cell viability

Cells communicate with one another to create microenvironments and share resources. One avenue by which cells communicate is through the action of exosomes. Exosomes are extracellular vesicles that are released by one cell and taken up by neighbouring cells. But how exosomes instigate communication between cells has remained largely unknown. Researchers from the University of New South Wales present evidence ...

Exosomes mediated transfer of lncRNA UCA1 results in increased tamoxifen resistance in breast cancer cells

lncRNA

In this study, researchers at the People’s Hospital of Shouguang compared the loading of urothelial carcinoma-associated 1 (UCA1) in exosomes between tamoxifen sensitive and tamoxifen resistant breast cancer cells and further investigated the role of exosomal transfer of UCA1 in the development of tamoxifen resistance in estrogen receptor (ER) positive breast cancer cells. The researchers isolated exosomes from the culture ...

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 ...

A comparative analysis of lncRNAs in prostate cancer exosomes and their parental cell lines

lncRNA

Prostate cancer is the second leading cancer in men world-wide. Due to its heterogeneous nature, a considerable amount of research effort has been dedicated in identifying effective clinical biomarkers with a focus on proteins, messenger RNA and microRNAs. However, there is limited data on the role and expression of long noncoding RNAs (lncRNAs) in prostate cancer exosomes. Researchers from the ...

Circulating long RNAs in serum extracellular vesicles: Their Characterization and Potential Application as Biomarkers for the Diagnosis of Colorectal Cancer

lncRNA

Long non-coding RNA and mRNAs are long RNAs (> 200 nucleotides) compared to microRNAs. In blood, long RNAs may be protected by serum extracellular vesicles, such as apoptotic bodies (ABs), microvesicles (MVs), and exosomes (EXOs). They are potential biomarkers for identifying cancer. Sera from 76 pre-operative CRC patients, 76 age- and sex-matched healthy subjects and 20 colorectal adenoma (CA) patients ...

Exosomal Long Noncoding RNAs are Differentially Expressed in Cervical Cancer Patient Samples

lncRNA

As the second leading cause of cancer morbidity and death in women, cervical cancer remains an important public health problem worldwide. Novel biomarkers with high sensitivity and specificity for the early detection and diagnosis of cervical cancer are urgently needed. Increasing evidence shows that long noncoding RNAs (lncRNAs) are differentially expressed in cancer tissues and may serve as diagnostic markers. ...
