U.S. scientists have successfully engineered blood vessels from human vascular cells in the lab

Tissue engineering has made considerable progress in the past decade, but advances have stopped short of clinical application for most tissues. For elderly patients tissue-engineered arteries could provide grafts for bypass surgery.

Research challenges the evolutionary paradigm that continuous alterations occur during the course of genome evolution

Researchers report today that regions of the human genome have been hotspots for acquiring duplicated DNA sequences - but only at specific time-points during evolution.

Arteries bio-engineered from elderly cells

Researchers from Duke University's Medical Center and Pratt School of Engineering have demonstrated that they can grow new human blood vessels from cells taken from patients who especially need such assistance – older adults with cardiovascular disease.

People who smoke or are obese are biologically older than slim individuals and non-smokers

Obesity and smoking are important risk factors for many age-related diseases. Tim Spector (St. Thomas’ Hospital, UK) and colleagues in the USA looked for evidence of ageing at a molecular level in smokers and obese individuals.

Bio-engineered skin provides clues to melanoma development

When it comes to the deadly skin cancer melanoma, studying functional tissue rather than cell lines may better provide insight into the disease's development, according to new research from a Howard Hughes Medical Institute predoctoral fellow at Stanford University School of Medicine.

MicroRNAs play an important role in human cancer

Over the past few years, scientists have discovered that a new class of genetic regulators called "microRNAs" influences normal human growth and development. Now, researchers have found that microRNAs also play an important role in human cancer. The findings are published in today's issue of the journal Nature (June 9).

Researchers link aberrant 'microRNA' expression to human cancer

New understanding of microRNAs

Ribonucleic acid, or RNA, has long been thought to be important only to translate a gene's DNA into the proteins that are cells' workhorses. But new evidence shows that tiny bits of RNA not used to make proteins actually play central roles in normal biology and in the development of cancers.

Study is the first to identify involvement of chromosome 21 in developmental regression autism

A new Cincinnati Children's Hospital Medical Center study links regions of two chromosomes to susceptibility for a type of autism characterized by regression in development. Developmental regression can include the loss of previously acquired language, social skills or both.

Computer simulation helps understand DNA transcription process

New York University chemists have employed a computer simulation whose results have enhanced scientific understanding of the DNA transcription process. The study, funded by the National Institutes of Health, appears in the June 7 issue of the Proceedings of the National Academy of Sciences.

Scientists have uncovered the structure of a network of proteins that help regulate the life cycle of cells

Scientists at Memorial Sloan-Kettering Cancer Center (MSKCC) have uncovered the structure of a network of proteins that help regulate the life cycle of cells. Understanding the network's physical layout is an important step toward learning its precise function, and in finding ways to correct flaws in the system that could lead to cancer.

The bacteria that cause food poisoning, bubonic plague, and whooping cough all deploy the same weapon to infect the body

A molecular "syringe" sticks out of the bacteria, pokes a hole in a nearby cell, and squirts in venomous proteins that hijack the cell's machinery.

Bald men can blame mum!

Despite an enormous range of treatments, obscure lotions and tinctures there appears to be very few successful counter-measures for hair loss in men. Beginning with receding hairlines, every second man suffers from hair loss to some degree, and it has always been suspected that hereditary factors are important in causing hair loss.

Disease progression model of pancreatic cancer developed

Building on previous work, researchers at the University of Pennsylvania School of Medicine have developed an animal model of pancreatic cancer that closely mimics disease progression in humans. From this, they hope to develop new treatments for this deadly disease.

Lower doses of chemo just as effective in childhood cancers

In the latest research into treating a common childhood cancer, paediatric oncologist Allen Chauvenet, is optimistic that the long-term side effects that survivors experience as they grow into adulthood can be reduced.

Deletion on chromosome 11q may guide decision to use chemotherapy for neuroblastoma

When genes are deleted on a particular section of chromosome 11, the result is an aggressive form of the childhood cancer neuroblastoma. A new study suggests that detecting this genetic deletion during the initial evaluation of children with neuroblastoma may indicate to physicians that they should recommend a more aggressive regimen of chemotherapy to fight the cancer.

Laboratory model of immune system overcomes ethical constraints on studies of hematopoietic stem cells in humans

Scientists at St. Jude Children’s Research Hospital have joined with colleagues at several other institutions to develop a laboratory model of the human immune system. This model will allow scientists to study ways for improving the results of hematopoietic stem cell (HSC) transplantation without putting patients at risk.

Scientists take aim at virulent bacteria by decoding machinery of key control enzyme

By deciphering the ingenious mechanism used by a particular enzyme to modify bacterial chromosome chemistry, scientists have come a step closer to designing a new kind of drug that could stop virulent bacterial infections in their tracks. Their research will be published in the May 6 issue of the journal Cell.

Mosaic Analysis with Double Markers (MADM) - A powerful new tool to study diseases and genetics

A powerful laboratory technique used by fruit fly geneticists for more than a decade is now available to scientists studying genes and diseases in mice.

Researchers make new advances in determining the structure of all possible DNA sequences

Oregon State University researchers have made significant new advances in determining the structure of all possible DNA sequences – a discovery that in one sense takes up where Watson and Crick left off, after outlining in 1953 the double-helical structure of this biological blueprint for life.
