MicroRNA News and Research

RSS

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.

New genetic testing method increases the precision of biomarker analysis

Estonian scientists have announced the invention of a genetic testing technology that allows the number of clinical biomarkers to be analyzed at the single-molecule level, which enhances the sensitivity of tests in precision medicine and will make them more affordable in future.

New approach turns B cells into factories that secrete sacs containing microRNAs

Cancer immunotherapy -- efforts to better arm a patient's own immune system to attack tumors -- has shown great potential for treating some cancers. Yet immunotherapy doesn't work for everyone, and some types of treatment can cause serious side effects.

Using nanocarrier-delivered microRNA to target sepsis

One in three patients who die in the U.S. dies of sepsis, according to the Centers for Disease Control and Prevention. It is one of the leading causes of death in intensive care units and, with an estimated price tag of $20 billion in 2011, the most expensive condition that hospitals treat.

Researchers evaluate efficacy of salivary biomarkers for early detection of oral cancer

Over 90% of malign tumors in the head and neck are originated from carcinomas of squamous cells that appear in superficial areas of the oral cavity. Their detection with salivary biomarkers can contribute to their early treatment, before they transform into tumors.

Shortage of specific gene 'silencing' molecules linked with pediatric low-grade gliomas

Experimenting with lab-grown brain cancer cells, Johns Hopkins Medicine researchers have added to evidence that a shortage of specific tiny molecules that silence certain genes is linked to the development and growth of pediatric brain tumors known as low-grade gliomas.

Tracking down microRNA candidates linked to disease

What started as Ninad Oak's side project turned out into something much larger, his doctorate thesis. "The project started as my qualifying exam that I proposed at the end of my first year of graduate school," said Oak, a graduate student in molecular and human genetics in Dr. Sharon E. Plon's lab. "This was an off topic qualifying exam at the time, meaning the lab had not worked on this topic before."

Study finds evidence of lasting effects from head injuries at younger age than expected

There have been more and more cases confirming that repeated hits to the head have lifelong consequences for professional football players, but a new study by Orlando Health in collaboration with the Concussion Neuroimaging Consortium finds evidence of lasting effects from head injuries at a much younger age than expected.

Nanopore technology combined with DNA computing to catch early biomarkers for small cell lung cancer

Small Cell Lung Cancer is very aggressive, since the cancer cells not only quickly grow but also easily spread to entire body. Often SCLC can be diagnosed using several common tests unfortunately after spread of cancer cells, resulting in poor survival.

Urine exRNA may be source of biomarkers for muscular dystrophy

Massachusetts General Hospital researchers have found that extracellular RNA in urine may be a source of biomarkers for the two most common forms of muscular dystrophy, noninvasively providing information about whether therapeutic drugs are having the desired effects on a molecular level.
