A transcriptional arrest leads to a strong change in localization and dynamics of YmcA, YlbF and YaaT, supporting their involvement in global RNA degradation. (uni-marburg.de)
This tells us that regulating these RNA degradation pathways could have a tremendous impact on brain development. (microrna.pro)

Moreover, the versatility of the platform allows analysis of molecules from a few bases up to kilobases, which opens new avenues to analyze a broad range of native nucleic acid molecules. (cam.ac.uk)

In this study, we identified a long noncoding RNA (lncRNA), NXTAR (LOC105373241), that is located convergent with the AR gene and is repressed in human prostate tumors and cell lines. (genengnews.com)
Moreover, using our newly developed enrichment strategy, we have been able to fully demonstrate the power of both genetic and epigenetic analysis by measuring repeat length of the fragile X syndrome gene (FmrI) as well as methylation status of the CpG island located in its 5' UTR on the same molecule in healthy versus affected individuals.

Depixus® is developing a single molecule platform based on magnetic tweezer technology that will allow both genetic analysis of nucleic acid (either RNA or DNA ) as well as their potential epigenetic modification on a single platform at single base resolution. (cam.ac.uk)
RNA, the molecule that relays genetic information from DNA to protein has long been a target of chemical-based medication. (geneonline.com)
With RNA, doctors will soon be able to target treatments to individual patients, drug developers will be able to create new classes of drugs that address specific genetic populations, and practitioners will even be able to track treatment responses in real-time. (asme.org)

Samples including yeast and ENCODE cell line RNAs will be analyzed with unprecedented detection and quantitation performance. (grantome.com)

By examining the catalytic process of Bacillus halodurans RNase H1 in crystallo, however, we found that the two canonical Mg 2+ ions and an additional K + failed to align the nucleophilic water for RNA cleavage. (rcsb.org)

They found that this long noncoding RNA plays a key role in regulating the androgen receptor and vice versa. (drramon.com)

According to the research - conducted in mice implanted with human prostate tumor samples - restoring this so-called long noncoding RNA could be a new strategy to treat prostate cancer that has developed resistance to hormonal therapies. (genengnews.com)
We are interested in addressing this need-developing new therapies for patients who have developed resistance-and we believe the RNA molecule we've pinpointed may lead to an effective approach. (genengnews.com)
We don't know how many people will be helped with cutting-edge RNA-based therapies. (acs.org)

As a result, modification of tRNA molecules is impaired. (medlineplus.gov)

Recent discoveries implicating RNA in the pathogenesis of several forms of cancer and neuromuscular diseases have created a paradigm shift in drug discovery. (wikipedia.org)
Their findings are published in the journal Cancer Research in a paper titled, " Loss of long noncoding RNA NXTAR in prostate cancer augments androgen receptor expression and enzalutamide resistance . (genengnews.com)
More specifically, they've discovered that these molecules may hold promise for warning of malignancies such as esophageal cancer , where a lack of biomarkers makes it hard to detect and treat tumors early. (case.edu)
Our study opens a new area of investigation by implicating these RNA molecules as additional players in esophageal cancer," Guda said. (case.edu)
