NYU Awarded $1.2M from NIH to Investigate Gene Delivery for Oral Cancer Pain

Posted on June 27, 2016

The National Institute of Dental and Craniofacial Research (NIDCR), part of the National Institutes of Health (NIH), has awarded Drs. Brian Schmidt and Seiichi Yamano a $1.2 M (3-year) grant to test whether their nonviral gene delivery method can effectively and safely treat oral cancer pain.

Quality of life for oral cancer patients can be dismal.

“Most of my oral cancer patients have severe pain,” says Brian L. Schmidt, DDS, MD, PhD, professor in the Department of Oral and Maxillofacial Surgery at New York University College of Dentistry (NYU Dentistry) and director of NYU’s Bluestone Center for Clinical Research and of the NYU Oral Cancer Center. “A recent study revealed that oral cancer pain is often more severe than pain from any other type of cancer.”

Due to their severe pain, oral cancer patients have difficulty eating, drinking, or talking, leaving doctors with little or no choice other than to prescribe high doses of opioid medications.

“The clinical challenge of treating oral cancer pain is then compounded by the off-target effects produced by pharmacological agents which lack anatomical specificity,” notes Schmidt, “since high opioid doses generate unwanted side effects that create additional unintended suffering for the patient.”

“Gene therapy is emerging as an exciting alternative to opioids for the treatment of cancer pain,” says Seiichi Yamano, DDS, PhD, DMD, MMSc, associate professor in the Department of Prosthodontics at NYU Dentistry. “We seek to alleviate oral cancer pain by reversing epigenetic changes. Our gene therapy method will set the stage for a new class of medicines that selectively disrupt nociceptive signaling with fewer off-target effects. Our long-term goal is to develop an effective and safe treatment for oral cancer pain.”

Schmidt’s research team demonstrated that OPRM1 (the gene for the µ-opioid receptor) is methylated and down regulated in oral cancer tumors. They also demonstrated that OPRM1 re-expression following viral gene transduction significantly reduced cancer pain in a preclinical model. Expression of the µ-opioid receptor on the cancer led to the secretion of opioids into the cancer microenvironment.

Because of safety concerns and viral transduction inefficiency, Yamano created two novel nonviral hybrid vectors: a cell-permeable peptide (CPP) combined with either a cationic lipid (CPP/lipid) or a cationic polymer (CPP/polymer). These nonviral vectors have excellent transfection efficiency with little cytotoxicity across a range of cell lines including different types of cancer cells.

“In addition to their transfection efficiency, my non-viral vectors preferentially transfect oral cancer cells compared to normal cells,” says Yamano. “Transfection efficiency using the nonviral vector in oral cancer cells showed eight-fold more gene transfer than normal cells and higher expression than that for an adenoviral vector.

In preliminary work funded by a High Priority, Short-Term Project Award (R56DE025393) from the NIDCR, Schmidt and Yamano demonstrated that the nonviral vectors could be used to deliver OPRM1 to oral cancers and reverse cancer pain in the preclinical model.

“Dr. Yamano and I collaborated over the last five years in preparation for the work described in this current grant,” notes Schmidt. “I found that delivery of the OPRM1 gene into the cancer reversed cancer pain. I just needed a safe method to deliver the gene. Yamano’s nonviral method is ideal. Our previously awarded bridge funding allowed us to develop preliminary data for the application. Our long-term goal is to develop an effective and safe treatment for oral cancer pain. These studies are a significant step toward that goal. We foresee clinicians directly inoculating our nonviral vector into oral cancers.”

Children Consuming Sports Drinks Unnecessarily

Posted on June 27, 2016

A high proportion of 12 to 14 year olds are regularly consuming sports drinks socially, increasing their risk of obesity and tooth erosion, concludes a Cardiff University School of Dentistry survey.

Published today in the British Dental Journal, the survey looked at 160 children in four schools across South Wales and concluded that children are attracted to sports drinks because of their sweet taste, low price, and availability, with most parents and children not aware that sports drinks are not intended for consumption by children.

Half of the children surveyed claimed to drink sports drinks socially and most (80%) purchased them in local shops. The majority (90%) also claimed that taste was a factor and only 18% claimed to drink them because of the perceived performance enhancing effect. Price was one of the top three recorded reasons for purchase and, of particular concern, 26% of children also cited leisure centres as purchase sources.

Maria Morgan, senior lecturer in dental public health at Cardiff University, said: "The purpose of sports drinks are being misunderstood and this study clearly shows evidence of high school age children being attracted to these high sugar and low pH level drinks, leading to an increased risk of dental cavities, enamel erosion and obesity.

"Dental health professionals should be aware of the popularity of sports drinks with children when giving health education or advice or designing health promotion initiatives."

The Faculty of Sport and Exercise Medicine (FSEM) is calling for tighter regulation around the price, availability and marketing of sports drinks to children, especially surrounding the school area, to safeguard general and dental health.

Dr Paul D Jackson, President of the FSEM UK, said: "The proportion of children in this study who consume high carbohydrate drinks, which are designed for sport, in a recreational non-sporting context is of concern.

"Sports drinks are intended for athletes taking part in endurance and intense sporting events, they are also connected with tooth decay in athletesi and should be used following the advice of dental and healthcare teams dedicated to looking after athletes. Water or milk is sufficient enough to hydrate active children, high sugar sports drinks are unnecessary for children and most adults."

Russ Ladwa, chair of the British Dental Association's Health and Science Committee, added: "The rise of sports drinks as just another soft drink option among children is a real cause for concern, and both parents and government must take note. They are laden with acids and sugars, and could be behind the decay problems we're now seeing among top footballersii.

"Sports drinks are rarely a healthy choice, and marketing them to the general population, and young people in particular, is grossly irresponsible. Elite athletes might have reason to use them, but for almost everyone else they represent a real risk to both their oral and their general health."

The survey also concluded that there is particular confusion over the definition of a sports versus an energy drink. However, from a dental and wider health perspective, these two drinks have similar detrimental effects due to their high sugar content and low pH.

In supermarkets and shops, sports drinks are often sold alongside other sugar sweetened beverages. This is misleading children and parents by indicating that they are meant for use by everyone.

The study - A survey of sports drinks consumption amongst adolescents - is published in the British Dental Journal.

Development of Drugs for Local Treatment of Oral Conditions

Posted on June 27, 2016

Seoul, Republic of Korea – At the 94th General Session & Exhibition of the International Association for Dental Research, researcher W. Peter Holbrook, University of Iceland, presented a study titled “Development of Drugs for Local Treatment of Oral Conditions.” The IADR General Session was held in conjunction with the 3rd Meeting of the IADR Asia Pacific Region and the 35th Annual Meeting of the IADR Korean Division.

Several medications commonly prescribed for oral mucosal administration are actually intended for transdermal application. Many conditions affecting the oral mucosa require frequent or long-term treatments and some treatments are systemically applied. Clinical resistance and patient intolerance of such treatments may develop. There is thus a constant need to address these problems through the development of less side-effect prone drugs.

Researchers at the University of Iceland have developed several new formulations for topical treatments of oral mucosal conditions and carried out appropriate clinical trials. The main area of this research has been the inhibition of matrix metallo-proteinase activity using topical doxycycline, initially in order to treat aphthous ulceration. The antimicrobial compound monocaprin was also tested for activity against herpes virus and, in combination with doxycycline, was developed in an active formulation for treating cold sores (canker sores). Monocaprin also has anticandidal activity that has been evaluated among geriatric patients with denture stomatitis.

Topical application of doxycycline was very effective in promoting healing of mucosal lesions. Monocaprin reduced counts of Candida rapidly and significantly. The results of these clinical studies have been very promising when compared to the conventional treatments available in Iceland and abroad. Stability of the active components has recently been effectively addressed and current research is aimed at different types of drug delivery systems in order to optimize drug delivery to the local mucosal site. This includes drug release time and mucoadhesive capacity of the formulation, thereby attempting to develop more disease-specific drug delivery systems.

This research was funded by grants from the Icelandic Research Council (Rannis) and the University of Iceland.

Researchers Study HPV Infection in Leukoplakia in the Last Decade

Posted on June 27, 2016

Seoul, Republic of Korea – At the 94th General Session & Exhibition of the International Association for Dental Research, researcher Jonas Sundberg, University of Gothenburg, Sweden, presented a study titled “Increased Expression of p16 in Oral Leukoplakia the Last Decade.”

During the last two decades an increase in incidence of oropharyngeal carcinomas related to human papilloma virus (HPV) infection has been reported. Although a casual association between lekoplakia, oral cancer, and HPV has been suggested in several reports, no conclusive evidence has been presented. To assess the presence of HPV, the tumor suppressing protein p16 is commonly used as a surrogate marker for HPV infection. The aim of the present study is to investigate whether p16 expression in tissue specimens from lekoplakia has increased during the last decade, which may indicate an increase in incidence of oral HPV infection.

A patient cohort with tissue specimens obtained between 1992 and 2001 and a cohort where specimens were obtained between 2011 and 2015 and with histopathological diagnoses of benign hyperkeratosis or hyperkeratosis with dysplasia were examined. Immunohistochemistry was performed using a monoclonal antibody (clone E6H4; Roche Ltd) visualizing p16. Digitalized images of sections were obtained and a semiquantitative scale (0-5) was used to enumarate p16 expression in oral epithelium.

In the 2011-2015 cohort lekoplakia epithelium showed a significant increase (P = .02) in grade 4 and 5 p16 expression in comparison with lekoplakia epithelium in the 1992-2001 cohort. In lekoplakia presenting with dysplasia, grade 4 and 5 p16 expression also increased significantly (P = .0001) over time when comparing the cohorts. The results indicate an increase in HPV infection in lekoplakia during the last decade. Researchers are further investigating the presence of HPV DNA utilizing polymerase chain reaction is presently undertaken.

This research was funded by the Regional Research Council, Region Västra Götaland, Assar Gabrielsson Foundation and the Swedish Dental Society.
