Allied Healthcare announces Coridon license to vector technology

Allied Healthcare Group (ASX: AHZ) has announced an update on the progress of Coridon, its investment company founded by Professor Ian Frazer and working on developing the next generation of vaccines. Included in these activities, Cordon has entered into a license agreement with Nature Technology Corporation (NTC) and has contracted VGXI Inc. in the US for production of clinical material for the Phase I study scheduled to begin later this year.

Study pinpoints compounds that repress cancer gene’s activity

A research team pursuing one of the most commonly altered genes in cancer has laid a critical foundation for understanding this gene that could point the way toward developing drugs against it. A recent study of cancer genetics pointed to the gene MCL1, which encodes a protein that helps keep cells alive

Gene function preserved despite structural differences in the DNA

Chloroplasts, the plant cell's green solar power generators, were once living beings in their own right. This changed about one billion years ago, when they were swallowed up but not digested by larger cells. Since then, they have lost much of their autonomy.

Transcription factors do not act like an 'on-off' switch

A UNC-led team of scientists has now shown that transcription factors don't act like an 'on-off' switch, but instead can exhibit much more complex binding behavior.

Scientists transform skin cells directly into induced neurons

Until recently, the production of pluripotent "multipurpose" stem cells from skin cells was considered to be the ultimate new development. In the meantime, it has become possible to directly convert cells of the body into one another - without the time-consuming detour via a pluripotent intermediate stage. However, this method has so far been rather inefficient.

Research on how cells cope with stress could lead to more effective cancer treatment

Both radiation and many forms of chemotherapy try to kill tumors by causing oxidative stress in cancer cells. New research from USC on a protein that protects cancer and other cells from these stresses could one day help doctors to break down cancer cells' defenses, making them more susceptible to treatment.

Reactivation of p53 may be a highly selective treatment modality for virally-induced lymphoma

Kaposi's sarcoma herpesvirus (KSHV) is a human tumor virus and an etiological agent for Kaposi's sarcoma and primary effusion lymphoma (PEL). PELs are aggressive lymphomas with reported median survival time shorter than six months after diagnosis.

Scientists discover why rapamycin causes diabetic-like symptoms in patients

Scientists at Dana-Farber Cancer Institute have discovered why diabetic-like symptoms develop in some patients given rapamycin, an immune-suppressant drug that also has shown anti-cancer activity and may even slow ageing.

Researchers figure out how rapamycin causes diabetes

The drug known as rapamycin is widely used by cancer and transplant patients, and there are hints that it might even help us put off old age and live longer. But, it also comes with a downside: rapamycin leads to diabetes in as many as 15 percent of the people who take it.

Researchers discover regulation and functional significance of acute phase response during pneumonia

Researchers at Boston University School of Medicine (BUSM) have discovered the regulation and functional significance of the acute phase response during a lung infection. The findings, which will be published in the May edition of the Journal of Clinical Investigation, demonstrate that the liver responds in order to increase defenses in the blood that prevent localized infections from spreading throughout the body.

Three leading cancer researchers to chair symposia at ACCR meeting

Three leading cancer researchers at Albert Einstein College of Medicine of Yeshiva University have been selected to chair symposia at this year's annual meeting of the American Association for Cancer Research, which will be held in Chicago from March 31 to April 4.

Researchers generate artificial thymus tissue to enable T cell maturation

The thymus plays a key role in the body's immune response. It is here where the T lymphocytes or T cells, a major type of immune defence cells, mature. Different types of T cells, designated to perform specific tasks, arise from progenitor cells that migrate to the thymus from the bone marrow. Researchers at the Max Planck Institute of Immunology and Epigenetics in Freiburg have generated artificial thymus tissue in a mouse embryo to enable the maturation of immune cells.

Study explains how rapamycin also causes insulin resistance

A Penn- and MIT-led team explained how rapamycin, a drug that extends mouse lifespan, also causes insulin resistance. The researchers showed in an animal model that they could, in principle, separate the effects, which depend on inhibiting two protein complexes, mTORC1 and mTORC2, respectively.

Switch may release fuel and materials for rapid growth and formation of layers that later become organs

Shortly after a mouse embryo starts to form, some of its stem cells undergo a dramatic metabolic shift to enter the next stage of development, Seattle researchers report today. These stem cells start using and producing energy like cancer cells.

Study reveals central role played by DBIRD protein complex in gene transcription

In a study published this week in the journal Nature, researchers at the University of Liège's GIGA Unit, together with English and German teams, reveal the central role played by a protein complex, unknown up to now, in gene transcription.

Study determines why blood oranges develop anthocyanin pigments

The anthocyanin pigments that provide the "blood" color of blood oranges are not produced in significant amounts unless the fruit is exposed to cold conditions during its development or post-harvest. No cold exposure means poor anthocyanin production and the loss of the entire crop. This means that blood oranges can be grown in many areas of the world, but they are most likely to be exposed to the correct temperature conditions in only a few regions, including their major area of production in Sicily.

Hedgehog and mTOR pathway are active in esophageal cancer

Identification of a non-traditional pathway for spiriting a cancer-promoting protein into the cell nucleus points to a possible combination therapy for esophageal cancer and indicates a mechanism of resistance for new drugs that attack the Hedgehog pathway.

Klf4 protein an important regulator of inflammation: HNK study

Microglia are the first line defence of the brain and are constantly looking for infections to fight off. Overactive microglia can cause uncontrolled inflammation within the brain, which can in turn lead to neuronal damage. New research published in BioMed Central's open access journal Journal of Neuroinflammation shows that, honokiol (HNK) is able to down-regulate the production of pro-inflammatory cytokines and inflammatory enzymes in activated microglia via Klf4, a protein known to regulate DNA.

Deletion of Hms1 protein inhibits Candida albicans infection

Scientists at the University of Toronto have found a molecular mechanism that plays a key role in the transition of Candida albicans yeast into disease-causing fungus-one of the leading causes of hospital-acquired infection.
