Link between smoking intensity and bladder cancer prognosis

Smoking not only causes bladder cancer-it also affects its course, in that people who smoke more have greater likelihood of developing more aggressive and deadly disease. That is one of the conclusions of a new study published early online in CANCER, a peer-reviewed journal of the American Cancer Society.

Clathrin protein may have a role in suppressing tumors

Newly published research by Indiana University structural biologist Joel Ybe and colleagues identifies a "topology switch" in the protein clathrin, the function of which may shed light on molecular processes involved in tumor suppression.

p53 activation suppresses malic enzyme expression and leads to senescence in pre-cancerous cells

It is perhaps impossible to overstate the importance of the tumor suppressor gene p53. It is the single most frequently mutated gene in human tumors. p53 keeps pre-cancerous cells in check by causing cells, among other things, to become senescent - aging at the cellular level. Loss of p53 causes cells to ignore the cellular signals that would normally make mutant or damaged cells die or stop growing.

GeneTex to introduce new EasyBlot reagent

GeneTex, a leading manufacturer of high-quality antibodies, is pleased to announce that they will be launching EasyBlot, a new secondary antibody reagent that eliminates the interference that has long plagued immunoprecipitation (IP) experiments when the IP and western blot primary antibodies are from the same host.

TSC22D4 gene plays a key role in the onset of cachexia

Cachexia or wasting is a condition affecting up to 70 percent of cancer patients, depending on the type of cancer. It is characterized by a dramatic loss of body weight that is independent of food intake. Cachexia is seen particularly often and most pronounced in patients suffering from cancers of the digestive tract and the lungs.

Over-expression of NEK2 in cancer cells significantly enhances drug resistance

Increased NEK2 gene expression linked to increased drug resistance, faster cancer growth, and poorer patient outcome - The finding may improved diagnostic and prognostic tools for cancer care and could lead to improved cancer therapies

Aggressive breast cancer’s metastasis molecular switch identified

Scientists at Weill Cornell Medical College have discovered the molecular switch that allows aggressive triple negative breast cancer cells to grow the amoeba-like protrusions they need to crawl away from a primary tumor and metastasize throughout the body. Their findings, published in Cancer Cell, suggest a novel approach for developing agents to treat cancer once it has spread.

Bionic devices: an interview with Dr Rylie Green

Bionic devices are implants which replace biological functions which have been lost due to nerve damage. They use electrical signals to stimulate the remaining nerve cells following disease or injury. Although the term bionic was only coined in the late 1950s, the earliest bionic devices were cardiac pacemakers, developed in the early 1900s. However the first commercial implantable units were not available until the 1950s.

Reviewing the latest methods for characterizing biomaterials

Biomaterials and medical devices must be rigorously tested in the laboratory before they may be implanted into test subjects. By ensuring that these test methods are both quick and efficient, an increased number of materials can be tested and working implants can be produced more rapidly. The development of such tests is therefore essential to biomedical advancement, and Characterization of biomaterials reviews the latest methods for defining properties and characterizing materials. Characterization of biomaterials discusses a wide array of techniques and various unique approaches to the problems faced in characterizing biomaterials, whilst also providing information on standards and methods for assessing the safety and biocompatibility of biomaterials.

Multidisciplinary team work on proactive approach to flu vaccine design

An internationally recognized expert in viruses, Robert W. Finberg, MD, the Richard M. Haidack Professor of Medicine and chair and professor of medicine at the University of Massachusetts Medical School, is lead investigator on a $12 million project to develop new ways of predicting how the influenza virus changes and evolves in response to anti-viral drugs and the human immune system. This approach has promise for becoming a pivotal tool in creating a more effective vaccine against the virus.

Additional insights into workings of ALVAC vaccine against HIV

Four years ago, a potential HIV vaccine showed promise against the virus that causes AIDS, but it fell short of providing the broad protection necessary to stem the spread of disease.

Repression of PTB protein in fibroblasts can convert pluripotent stem cells into functional neurons

Repression of a single protein in ordinary fibroblasts is sufficient to directly convert the cells - abundantly found in connective tissues - into functional neurons. The findings, which could have far-reaching implications for the development of new treatments for neurodegenerative diseases like Huntington's, Parkinson's and Alzheimer's, will be published online in advance of the January 17 issue of the journal Cell.

Baboon embryonic stem cells can be programmed to completely restore severely damaged arteries

Scientists at the Texas Biomedical Research Institute have for the first time demonstrated that baboon embryonic stem cells can be programmed to completely restore a severely damaged artery. These early results show promise for eventually developing stem cell therapies to restore human tissues or organs damaged by age or disease.
