Regulus Earns $10.0 Million Milestone Payment from AstraZeneca and Achieves Key Goal for 2015

regulus therapeutics logoLA JOLLA, Calif., Dec. 18, 2015 /PRNewswire/ — Regulus Therapeutics Inc. (NASDAQ: RGLS), a biopharmaceutical company leading the discovery and development of innovative medicines targeting microRNAs, announced today that dosing has begun in a first-in-human Phase I clinical study of RG-125(AZD4076), by its collaboration partner AstraZeneca. RG-125(AZD4076) is a GalNAc-conjugated anti-miR-103/107 oligonucleotide that has been shown to improve insulin sensitivity and glucose tolerance in animal models. RG-125(AZD4076) was jointly identified and selected as a clinical candidate in April 2015 by AstraZeneca under the companies’ strategic alliance to discover, develop and commercialize microRNA therapeutics. AstraZeneca will pay Regulus $10.0 million and will assume further development of RG-125(AZD4076).

Previous research has demonstrated a causative role of microRNAs in pathophysiological processes of metabolic diseases, and increased expression of miR-103/107 in the liver has been associated with insulin resistance in people with non-alcoholic steatopheatitis (NASH), or fatty liver disease.  In mechanistic studies, RG-125(AZD4076) showed effects on biological pathways implicated in NASH progression.

“RG-125(AZD4076) acts as a novel insulin sensitizer which represents a potential new mechanism to treat patients with metabolic diseases such as type 2 diabetes and NASH,” said Paul Grint, MD, President and Chief Executive Officer of Regulus. “Regulus is pleased to [click to continue…]

New study connects the cancer gene Lin28 to glucose metabolism; may shed light on unifying principles in type 2 diabetes

BOSTON, Sept. 29, 2011 /PRNewswire-USNewswire/ — A pathway activated in cancer plays an unexpected key role in metabolic diseases like type 2 diabetes, according to a study by researchers at Children’s Hospital Boston. Evidence that the Lin28/let-7 pathway influences the cellular response to glucose provides a unifying theme to perplexing data that associates human genetic variation with diabetes risk.

The multi-institutional research team led by George Q. Daley, MD, PhD, director of Stem Cell Transplantation and a leader in the Stem Cell Research Program at Children’s Hospital Boston – reported their findings in the September 30 issue of the journal Cell.

Let-7 is a microRNA, a small RNA that dampens the expression of a large set of genes related to cell growth and development. Previously, the Daley lab reported that Lin28, an RNA-binding protein found at high levels in the embryo, blocks let-7 production and is aberrantly expressed in about 15% of all cancers.

“The relationship between Lin28 and let-7 is ancient, found in organisms as diverse as worms, mice, and humans,” said Daley, a professor of biological chemistry and molecular pharmacology at Harvard Medical School [click to continue…]


Diabetes and cancer: A shared biological basis

Contrary to what you might think, cancer and diabetes appear to have some biology in common. According to a report in the September 30th issue of the Cell Press journal, Cell, a pathway that initially drew attention for its role in embryonic stem cells and cancer also influences the odds that mice develop or resist diabetes.

Mice with high levels of the cancer-promoting proteins Lin28a or Lin28b become more sensitive to insulin and less prone to diabetes when on a high-fat diet, the new study shows.

“This highlights the overlap in the biology of these disorders,” said George Daley of Harvard Medical School. “It may be the same kinds of metabolic shifts that allow cancer cells to grow are also related to [whole-body] glucose metabolism.”

In fact, there were clues about such a connection, but “no obvious mechanism,” he says. For instance, studies have shown that cancer cells within a tumor are able to grow more rapidly by shifting the way they use glucose. Genome-wide association studies for type 2 diabetes have also pinpointed several susceptibility genes with known links to cancer or the cell cycle.

Daley’s team, including first authors Hau Zhu and Ng Shyh-Chang, had noticed earlier that an immature form of the microRNA (tiny bits of RNA that silence genes by targeting messenger RNA) known as let-7 is abundant in stem cells. “It allows stem cells to be stem cells,” Zhu says.

Let-7 is also important in preventing cancer, Zhu explained, and its activity is [click to continue…]


– Work of scientists with Regulus, Alnylam and ETH Zurich shows microRNAs 103/107 are upregulated in mouse models of obesity; targeting with anti-miRs improves glucose homeostasis and insulin sensitivity –

LA JOLLA, Calif., and CAMBRIDGE, Mass., June 8, 2011 /PRNewswire/ — Regulus Therapeutics Inc., a biopharmaceutical company leading the discovery and development of innovative medicines targeting microRNAs, and Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), a leading RNAi therapeutics company, today announced the publication in Nature of new pre-clinical data in mice about the antagonism of microRNA-103 and microRNA-107 (miR-103/107). Data from a collaborative study performed by Regulus, Alnylam and ETH Zurich demonstrated that antagonism of miR-103/107 with proprietary chemically modified anti-miR oligonucleotides could promote insulin signaling in both liver and adipose tissue.  Silencing miR-103/107 in animal models of obesity improved glucose homeostasis, suggesting that these microRNAs are potential targets for the treatment of diabetes.

Defects in insulin signaling are among the most common and earliest defects that predispose an individual to the development of type 2 diabetes. The new findings demonstrated that miR-103/107 are upregulated in obese mice, and silencing with anti-miRs could improve glucose homeostasis and insulin sensitivity, while gain of function in liver or fat caused impaired glucose homeostasis. Direct targets of miR-103/107 identified include [click to continue…]

MicroRNAs a Potential Therapeutic Target to Reduce Diabetic Related Amputation

January 13, 2011

Researchers at the University of Bristol have shown in an experimental cell study that conditions mimicking diabetes and a lack of blood supply to a tissue increased microRNA-503 and impaired the ability of endothelial cells, which line the interior surface of blood vessels. Alternatively, slowing down microRNA-503 improved the capability of endothelial cells to duplicate […]
