The Future of Biomarkers and Genomics

lncrna

from UroToday.com by  Zachary Klaassen, – Professor Manfred Wirth from Germany provided an update on the future of biomarkers and genomics at this afternoon’s EAU Update in Prostate Cancer in Vienna, Austria. Dr. Wirth divided his presentation into three subsections: Why are biomarkers needed for prostate cancer? There are several reasons according to Dr. Wirth why biomarkers are needed for prostate cancer, ...

Post-doc Positions Available – Bioinformatics and Cancer Cell Biology

lncRNA

Job Description Postdoctoral Associate positions (Bioinformatics and Cancer Cell Biology) are available to study the role of non-coding RNAs (long noncoding RNA and microRNAs) in our laboratory at Sanford-Burnham Medical Discovery Institute, Orlando FL USA.  Several putative oncogenic and tumor suppressor non-coding RNAs have been identified ( Lee et al Science Advances 2017 3(5): e1602505, Mazar et al Mol. Cell. Biol. ...

Long noncoding RNAs in the p53 network

lncRNA

The tumor-suppressor protein p53 is activated in response to numerous cellular stresses including DNA damage. p53 functions primarily as a sequence-specific transcription factor that controls the expression of hundreds of protein-coding genes and noncoding RNAs, including microRNAs (miRNAs) and long noncoding RNAs (lncRNAs). While the role of protein-coding genes and miRNAs in mediating the effects of p53 has been extensively ...

Metastasis-associated long noncoding RNAs in gastrointestinal cancer: Implications for novel biomarkers and therapeutic targets

lncRNA

Long non-coding RNAs (lncRNAs), a newly discovered class of ncRNA molecules, have been widely accepted as crucial regulators of various diseases including cancer. Increasing numbers of studies have demonstrated that lncRNAs are involved in diverse physiological and pathophysiological processes, such as cell cycle progression, chromatin remodeling, gene transcription, and posttranscriptional processing. Aberrant expression of lncRNAs frequently occurs in gastrointestinal cancer ...

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 ...

CANTATAdb – a Collection of Plant Long Non-coding RNAs

lncRNA

Long non-coding RNAs (lncRNAs) represent a class of potent regulators of gene expression that are found in a wide array of eukaryotes, however, our knowledge about these molecules in plants is still very limited. In particular, a number of model plant species still lack comprehensive datasets of lncRNAs and their annotations and very little is known about their biological roles. ...

No longer junk: Role of long noncoding RNAs in autism risk

lncRNA

by Nikolaos Mellios, Mriganka Sur RNA acts as the intermediary between genes and proteins, but the function of pieces of RNA that do not code for protein has, historically, been less clear. Researchers have ignored these noncoding RNAs until recently for not complying with the central dogma of biology — that a straight line runs from gene to RNA (transcription) ...

The non-coding transcriptome as a dynamic regulator of cancer metastasis

lncRNA

Since the discovery of microRNAs, non-coding RNAs (NC-RNAs) have increasingly attracted the attention of cancer investigators. Two classes of NC-RNAs are emerging as putative metastasis-related genes: long non-coding RNAs (lncRNAs) and small nucleolar RNAs (snoRNAs). LncRNAs orchestrate metastatic progression through several mechanisms, including the interaction with epigenetic effectors, splicing control and generation of microRNA-like molecules. In contrast, snoRNAs have been ...

Featured long non-coding RNA – H19

lncRNA

Abundantly expressed in fetal tissues and adult muscle, the developmentally regulated H19 long noncoding RNA (lncRNA) has been implicated in human genetic disorders and cancer. However, how H19 acts to regulate gene function has remained enigmatic, despite the recent implication of its encoded miR-675 in limiting placental growth. A team led by researchers at Yale University School of Medicine demonstrate ...
