IDOM researchers overturn textbook view of liver metabolism

A team led by researchers from the Institute for Diabetes, Obesity and Metabolism (IDOM) at the Perelman School of Medicine, University of Pennsylvania, has overturned a "textbook" view of what the body does after a meal.

Electronic properties of DNA can play a role in early diagnosis of cancer-causing mutations

Scientists have discovered that cancer-causing genetic mutations have better-disguised electronic signatures than other mutations - a trait which could help them fly under the radar of the body's defence mechanisms.

Tasmanian devil cancer genome mapped

Researchers, including those from Wellcome Trust Sanger Institute near Cambridge, have sequenced the genome of a facial cancer that is threatening the existence of the Tasmanian devil.

Biotech company defends patent on gene mutation for breast cancer

A US biotechnology company is defending the granting of a controversial patent over a common genetic mutation for breast cancer, rejecting accusations it amounts to the privatization of the human body.

Genomic instability allows malignant cells to acquire more deadly characteristics

Genomic instability caused by an erosion of the protective caps on chromosomes, followed by activation of an enzyme that reinforces those aps, allows malignant cells to evade destruction and acquire more deadly characteristics, researchers report in an Online Now article at the journal Cell.

Telomerase reactivation in malignant cells after genomic instability causes cancer progression

Inhibiting telomerase, an enzyme that rescues malignant cells from destruction by extending the protective caps on the ends of chromosomes, kills tumor cells but also triggers resistance pathways that allow cancer to survive and spread, scientists report in the Feb. 17 issue of Cell.

Gene that destroys cancerous cells also causes ageing

The role of one of our genes which protects us from cancer but could also cause us to age will be explained in a lecture at the University of Leicester.

Researchers discover identical antibiotic resistant genes in soil bacteria and in pathogens from clinics

Disease-causing bacteria's efforts to resist antibiotics may get help from their distant bacterial relatives that live in the soil, new research at Washington University School of Medicine suggests.

Frailty test for elderly also helps measure transplant candidates

A simple, 10-minute bedside assessment conducted prior to surgery appears to be the best method yet for predicting which kidney transplant patients will do well with their new organs, new Johns Hopkins research suggests.

Evolution of cancer genome to be discussed at 2012 AAAS annual meeting

Professor Mike Stratton, Director of the Wellcome Trust Sanger Institute, will speak about 'the evolution of the cancer genome' at the prestigious 2012 American Association for the Advancement of Science annual meeting. The AAAS annual meeting is one of the world's most widely recognized science events.

Scientists discover the off signal for inflammation

Proteins, the building block for all living organisms, are the ultimate transformers - able to splice and switch roles and functions within the human body. But when these changes go wrong, diseases such as cancers and arthritis may result, says University of British Columbia researcher Chris Overall.

New, under-recognized, much more potent variant of common bacterium

University at Buffalo researchers are expressing concern about a new, under-recognized, much more potent variant of a common bacterium that has surfaced in the U.S.

UB researchers express concern about a new variant of Klebsiella pneumoniae

University at Buffalo researchers are expressing concern about a new, under-recognized, much more potent variant of a common bacterium that has surfaced in the U.S.

Evolutionary biologist receives LRI grant for lupus research

Evolutionary biologist Harmit Singh Malik, Ph.D., of Fred Hutchinson Cancer Research Center, has received a $300,000 grant from the Lupus Research Institute to study the potential role of "genetic conflicts" in the development of lupus, an autoimmune disease.

Study reveals new guiding principles for cancer genomics

That our chromosomes can break and reshuffle pieces of themselves is nothing new; scientists have recognized this for decades, especially in cancer cells. The rules for where chromosomes are likely to break and how the broken pieces come together are only just now starting to come into view.

New potential strategy for KRAS-mutant colon cancers

Researchers from the Massachusetts General Hospital (MGH) Cancer Center have identified a new potential strategy for treating colon tumors driven by mutations in the KRAS gene, which usually resist both conventional and targeted treatments.

Study describes how multiple RNA binding proteins cooperatively control genetic splicing code

Understanding how RNA binding proteins control the genetic splicing code is fundamental to human biology and disease - much like editing film can change a movie scene. Abnormal variations in splicing are often implicated in cancer and genetic neurodegenerative disorders.

Researchers sequence genome of Tasmanian devil contagious cancer

Researchers have sequenced the genome of a contagious cancer that is threatening the Tasmanian devil, the world's largest carnivorous marsupial, with extinction. Cataloguing the mutations present in the cancer has led to clues about where the cancer came from and how it became contagious.

New transfection method changes genetic material of cancer cells

Researchers at Polytechnique Montr-al have succeeded in changing the genetic material of cancer cells using a brand-new transfection method. This major breakthrough in nanosurgery opens the door to new medical applications, among others for the treatment of cancers.

New preclinical data from Regulus' miR-21 study on kidney fibrosis

Regulus Therapeutics Inc., a biopharmaceutical company leading the discovery and development of innovative medicines targeting microRNAs, today announced that new preclinical data investigating the role of microRNA-21 (miR-21) in the treatment of kidney fibrosis has been published in the journal Science Translational Medicine.
