Scientists offer first genetic proof of new and rational treatment for osteoporosis

The so-called RANK protein and the molecule that binds to it, the RANK ligand or RANKL, form a focus of the work of Josef Penninger, director of the Institute of Molecular Biotechnology (IMBA) in Vienna. In 1999 his group deleted the RANKL gene from mice and showed that the RANK/RANKL system was the "master regulator" governing bone loss (Kong et al. 1999 Nature 402, 304-309).

Cells protect themselves against viruses and bacteria with novel non-genetic mechanism

When cells are confronted with an invading virus or bacteria or exposed to an irritating chemical, they protect themselves by going off their DNA recipe and inserting the wrong amino acid into new proteins to defend them against damage, scientists have discovered.

Alpha-fetoprotein, a well-tolerated agent for treatment and prevention of breast cancer

Researchers have found that hormones produced during pregnancy induce a protein that directly inhibits the growth of breast cancer. This protein, alpha-fetoprotein (AFP), may serve as a viable, well-tolerated agent for the treatment and prevention of breast cancer, according to findings published in Cancer Prevention Research, a journal of the American Association for Cancer Research.

CXCL5 molecule causes insulin resistance and type 2 diabetes in obese people

Many people who are overweight or obese develop insulin resistance and type 2 diabetes at some stage in their lives. A European research team has now discovered that obese people have large amounts of the molecule CXCL5, produced by certain cells in fatty tissue.

Therapeutic agents in soy can treat colon cancer, says study

A study conducted by Children's Hospital & Research Center Oakland scientists identifies a new class of therapeutic agents found naturally in soy that can prevent and possibly treat colon cancer, the third most deadly form of cancer. Sphingadienes (SDs) are natural lipid molecules found in soy that research shows may be the key to fighting colon cancer.

Oxagen completes £16 Million Series C round funding

Oxagen Limited, a drug discovery and development company specializing in inflammation, announced today the successful completion of a £16 Million ($26.7 Million) Series C round led by Novartis Venture Funds.

Studies examine interaction of ribosome with molecular partners

Two new studies reveal in unprecedented detail how the ribosome interacts with other molecules to assemble new proteins and guide them toward their destination in biological cells. The studies used molecular dynamics flexible fitting (MDFF) to examine the interaction of the ribosome with two prominent molecular partners.

Human Genome Sciences commences patient dosing in its HGS1029 inhibitor trial

Human Genome Sciences, Inc. and Aegera Therapeutics, Inc. today announced that HGS has initiated dosing in a Phase 1 clinical trial to evaluate the safety and tolerability of its lead IAP inhibitor, HGS1029, as monotherapy in patients with advanced lymphoid tumors.

Winship-led team identifies a way to exploit cancer cells' taste for glucose

The pedal-to-the-metal signals driving the growth of several types of cancer cells lead to a common switch governing the use of glucose, researchers at Winship Cancer Institute of Emory University have discovered.

Scientists discover new potential target for treating non-Hodgkin's lymphoma

Physician-scientists from Weill Cornell Medical College have discovered a molecular mechanism that may prove to be a powerful target for the treatment of non-Hodgkin's lymphoma, a type of cancer that affects lymphocytes, or white blood cells. By exploiting this mechanism, researchers have been able to powerfully suppress tumor formation in lab testing and in animal models.

Bacteria help in preventing inflammation after skin injury

On the skin's surface, bacteria are abundant, diverse and constant, but inflammation is undesirable. Research at the University of California, San Diego School of Medicine now shows that the normal bacteria living on the skin surface trigger a pathway that prevents excessive inflammation after injury.

Cancer promoting gene identified

Virginia Commonwealth University Massey Cancer Center and VCU Institute of Molecular Medicine researchers have identified a gene that may play a pivotal role in two processes that are essential for tumor development, growth and progression to metastasis. Scientists hope the finding could lead to an effective therapy to target and inhibit the expression of this gene resulting in inhibition of cancer growth.

Discovery holds promise in fighting cancer, AIDS and autoimmune disorders

Researchers at the University of Alabama at Birmingham (UAB) have uncovered the genetic identity of a cellular receptor for the immune system's first-response antibody, a discovery that sheds new light on infection control and immune disorders.

Discovery of Th22 cells may help in developing effective therapies for chronic skin and respiratory diseases

The newly discovered Th22 cells are a previously unknown subset of T helper cells. T helper cells are white blood cells that help activate other immune cells when the body is infected by viruses or bacteria. At the same time they help the body to tolerate own tissue and to prevent or curb inflammation.

Dutch researcher discovers how sulfate groups can be protected during molecule construction

Sulfate groups are crucial building blocks for many molecules but are difficult to handle. Dutch researcher Martijn Huibers has discovered how sulfate groups can be protected during the construction of a molecule. Thanks to his method new molecules, which could be used for the production of medicines, can now be constructed far more easily.

University of Michigan scientists discover how SEVI works

Since the discovery in 2007 that a component of human semen called SEVI boosts infectivity of the virus that causes AIDS, researchers have been trying to learn more about SEVI and how it works, in hopes of thwarting its infection-promoting activity.

Scientists closer to unraveling the mechanisms of gene regulation

A team led by Penn State's Ross Hardison, T. Ming Chu Professor of Biochemistry and Molecular Biology, has taken a large step toward unraveling how regulatory proteins control the production of gene products during development and growth.

High blood pressure: A major risk factor for stroke and heart disease

Today, Jamieson Laboratories, in partnership with the Victorian Order of Nurses (VON), is holding a one day Blood Pressure Blitz in Toronto's underground PATH system in an effort to educate consumers about the number one risk factor for stroke and a major risk factor of heart disease.

Researchers to discover new vaccine against infection from Lyme disease

A protein found in the saliva of ticks helps protect mice from developing Lyme disease, Yale researchers have discovered. The findings, published in the November 19 issue of Cell Host & Microbe, may spur development of a new vaccine against infection from Lyme disease, which is spread through tick bites.

Ligon Discovery raises $1 million

Ligon Discovery, Inc., which uses proprietary small molecule microarray technology to find drugs against high-value targets, today announced that it has raised $1M in seed financing led by incTANK Ventures. The company will use the capital to complete its initial discovery campaign that will screen over 100 high-value disease protein targets. With this investment, incTANK Ventures General Partner Christian Bailey joins the board.
