To validate our RNA-Sequencing data, we will perform metabolic profiling upon KDM depletion. (ntu.ac.uk)
Osteoporosis is a metabolic disease of bone characterized by low bone mass, micro-architectural deterioration of bone tissue and, consequently, increased bone fragility and susceptibility to fractures. (scienceinpoland.pl)

Regulus has identified several microRNAs that are dysregulated in fibrosis. (mirnablog.com)

The sugar molecule has a central position in the nucleotide, with the base attached to one of its carbons and the phosphate group (or groups) attached to another. (khanacademy.org)

Dr. Muneesh Tewari's project is on the cutting edge of a new technology whereby diagnosis, prognosis and optimal prostate-cancer treatment strategy might be determined by analysis of circulating microRNAs. (fredhutch.org)
In the present study, we will combine pathway- and network-based methods to decipher the regulatory action of 1,25(OH) 2 D 3 in prostate cancer cells on mRNA and microRNA level. (biomedcentral.com)

MicroRNAs can thus affect the occurrence of diseases such as cancer and could provide us with new possibilities for cancer treatment. (lu.se)

Thus, an important research objective has been to identify the adaptations within individual molecules that underlie tolerance. (nih.gov)

This result implies that the Arabidopsis embryo relies on microRNA restriction of ARF17 activity to achieve normal bilateral symmetry. (sciencedaily.com)

It was observed that when cancer cells were subjected to transfection with the precursor of miR-129, GALNT1 was subsequently down regulated by the direct targeting of miR-129. (wikipedia.org)
MicroRNAs have given cancer researchers a new perspective to understand and combat cancer. (wikipedia.org)
MicroRNA in cancer cells contains anomalies that would not be found in healthy cells. (udel.edu)
For example, certain microRNA are present in cancer cells but absent in healthy cells. (udel.edu)
The group calculated how nucleotides should be arranged to activate the cancer prodrug in the presence of cancer microRNA, but stay inactive and non-toxic in a non-cancerous environment where the microRNA are missing. (udel.edu)
When the cancer microRNAs were present and able to turn the DNA circuit on, cells were unable to grow. (udel.edu)
Nanoparticles will be used to deliver KDM inhibitors, microRNA mimics or their combination on a liver cancer-on-a-chip. (ntu.ac.uk)
Not all microRNAs in cancer cells have the same function. (ascopost.com)
These molecules appear to be cancer-specific and hold great promise for molecular profiling of tumors. (fredhutch.org)
Methods currently exist to pharmacologically manipulate molecules like miR-21,' said Dr Olson, who directs the Nancy B. and Jake L. Hamon Center for Basic Research in Cancer and the Nearburg Family Center for Basic and Clinical Research in paediatric Oncology. (myvmc.com)
