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.

Alnylam commences ALN-PCS Phase I trial in severe hypercholesterolemia

Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, announced today that it has initiated dosing in its Phase I clinical trial with ALN-PCS, an RNAi therapeutic targeting proprotein convertase subtilisin/kexin type 9, or PCSK9, for the treatment of severe hypercholesterolemia.

Researchers identify micro-RNA that regulates learning processes, Alzheimer's

Proteins are the molecular machines of the cell. They transport materials, cleave products or transmit signals - and for a long time, they have been a main focus of attention in molecular biology research. In the last two decades, however, another class of critically important molecules has emerged: small RNA molecules, including micro-RNAs. It is now well established that micro-RNAs play a key role in the regulation of cell function."A micro-RNA regulates the production of an estimated 300-400 proteins.

Researchers discover why tumors evolve

Like snakes, tumour cells shed their skin. Cancer is not a static disease but during its development the disease accumulates changes to evade natural defences adapting to new environmental circumstances, protecting against chemotherapy and radiotherapy and invading neighbouring organs, eventually causing metastasis.
