Researchers Make Possible Breakthrough in Oral Cancer Research

There may be a new, more definitive reason for why people develop oral or esophageal cancer.

New research developed by the University of Pennsylvania School of Medicine shows that a protein that enables cells to stick together is often not present or out of place when a person has oral or esophageal cancer. It’s not certain at this point, however, that the loss of the protein correlates to the presence of tumors.

Cancer in the oral cavity and esophagus affects more than 650,000 people every year.

The investigators made this finding by creating mice that did not have the protein, p120-catenin, in their oral-upper digestive tract. The results were that these mice developed squamous cell cancers.

Periodontal Stem Cell Transplantation Displays Early Success

New research indicates that periodontal ligament stem cells are the most effective of the clinically tested dental tissue-derived stem cells.

There were three different types that were tested. The research was published in the most recent issue of Cell Transplantation.

The South Korean research team demonstrated the study by using beagle dogs that had advanced periodontal disease to the point in which it affected their premolars and molars. These areas have some similarities as the areas in human dentition.

Dentists in England Will be Paid on Quality of Their Work

Dentists in England will be paid under a different system beginning this summer.

The dentists will get paid based on how many patients they see, not the kind of treatment they provide. This system will be tried in 62 dental practices.

In England, some dentists want to provide the treatment and be finished with the patient as soon possible. By doing that, it’s conceivable a dentist could earn more money than one who cares for a patient’s needs and the treatment suitable for his or her condition. This new system is designed to prevent these instances.

Oral Cancer Can Come from Alcohol Consumption

The risk of cancer may be increased by alcohol consumption.

A new study from Oxford University claims that 1 out of 10 cancer cases in men come from alcohol and 1 in 33 cases for women. Drinking may cause oral cancer, as well as breast cancer and esophageal cancer.

One of the discoveries of the study is that alcohol is a top risk factor for various forms of cancer. Drinking in moderate levels may the risk of cancer, but it's binge drinking and drinking heavily over longer periods that increase cancer risk even further.

Study Allows Researchers to Learn More About Human Taste Cells

Research from the Monell Center sheds new light on taste cells.

A study indicates that taste cells can be maintained in culture for seven months or more. This finding will allow scientists to get a better understanding of how human taste functions.

This information could enable scientists to generate new treatment for taste loss and possibly prevent taste loss for reasons varying from infection, radiation, chemotherapy, and other ways.

The taste cells are found in the papillae, which are the bumps on the tongue. The cells generate a taste based on the way the receptors interact with the chemicals. The cells can regenerate, an ability that most cells don’t have.
