In genetics, microRNAs (miRNA) are single-stranded RNA molecules of 21-23 nucleotides in length, which regulate gene expression. miRNAs are encoded by genes from whose DNA they are transcribed but miRNAs are not translated into protein (i.e. they are non-coding RNAs); instead each primary transcript (a pri-miRNA) is processed into a short stem-loop structure called a pre-miRNA and finally into a functional miRNA. Mature miRNA molecules are partially complementary to one or more messenger RNA (mRNA) molecules, and their main function is to down-regulate gene expression.

DNA imprinting defect may affect children diagnosed with osteosarcoma

DNA imprinting defect may affect children diagnosed with osteosarcoma

Children diagnosed with osteosarcoma may be impacted by a DNA imprinting defect also found in parents, according to new research from the Masonic Cancer Center, University of Minnesota. DNA imprinting is a phenomenon in which just one of the two inherited genes is active while the other is present but inactive. [More]

Four microRNAs appear to play critical roles in controlling cholesterol, triglyceride metabolism

Four microRNAs appear to play critical roles in controlling cholesterol, triglyceride metabolism

Four tiny segments of RNA appear to play critical roles in controlling cholesterol and triglyceride metabolism. In their report receiving advance online publication in Nature Medicine, a Massachusetts General Hospital-based research team describes finding how these microRNAs could reduce the expression of proteins playing key roles in the generation of beneficial HDL cholesterol, the disposal of artery-clogging LDL cholesterol, control of triglyceride levels and other risk factors of cardiovascular disease.

Scientists trace out intricate molecular pathway that may explain tamoxifen resistance in breast cancer patients

Scientists trace out intricate molecular pathway that may explain tamoxifen resistance in breast cancer patients

For reasons unknown, many patients with breast cancer treated with the estrogen receptor-blocking drug tamoxifen eventually become resistant to the treatment despite the fact that their cancer cells still have the estrogen receptor proteins that the drug normally targets. [More]
Dietary uptake of microRNAs certainly insufficient to affect physiological functions, reveal ETH biologists

Dietary uptake of microRNAs certainly insufficient to affect physiological functions, reveal ETH biologists

The scientific world was astonished when, in 2011, Chinese researchers claimed to have found evidence suggesting that minute fragments of plant genetic material - so-called microRNA molecules - of rice ingested from food could play a role in regulating physiological processes in the human body. If this is indeed true, it might even be possible to deliberately modify human physiological functions via this route, for instance by incorporating microRNAs into novel functional foods. [More]

Study reveals that miR-7 suppresses gastric cancer by inhibiting key signaling pathway

A study in The Journal of Cell Biology reveals that the microRNA miR-7 suppresses gastric (stomach) cancer by inhibiting a key signaling pathway, and that this protective mechanism is compromised by the cancer-causing bacterium H. pylori. Finding drugs capable of inducing miR-7 could therefore prove to be an effective treatment against the progression of gastric cancer. [More]
