Protein arginine methyltransferase-5 (PRMT5) plays an important role in cancer progression by repressing the expression of key tumor suppressor genes via the methylation of transcriptional factors and chromatin-associated proteins. However, very little is known about the expression and biological role of PRMT5 in head and neck cancer. In this study, we examined expression profile of PRMT5 at subcellular levels in oropharyngeal squamous cell carcinoma (OPSCC) and assessed its correlation with disease progression and patient outcome...

Intraoperative detection of residual malignant cells at tumor margins following excision of primary tumors could help improving surgery and thus patients' outcome. The feasibility of the tumor antigens epidermal growth factor receptor (EGF-R) and epithelial cell adhesion molecule (EpCAM) for antibody-dependent confocal laser scanning endomicroscopy (CLE)-mediated visualization of malignant cells was addressed. Both tumor antigens are highly and frequently expressed in the majority of carcinomas, including head and neck squamous cell carcinomas (HNSCC), and represent prognostic and therapeutic tumor target molecules...

Ionizing radiation is one of the most common cancer treatments; however, the treatment leads to a wide range of debilitating side effects. In patients with head and neck cancer (HNC), the surrounding normal salivary gland is extremely sensitive to therapeutic radiation, and damage to this tissue results in various oral complications and decreased quality of life (QOL). In the current study, mice treated with targeted head and neck radiation showed a significant increase in double-stranded breaks (DSB) in the DNA of parotid salivary gland cells immediately after treatment, and this remained elevated 3 h posttreatment...

The study was carried out on 126 mares of the Polish Konik horse breed. Mares were bred under a stable system housing and they came from five leading conservation breeding centres. The mares were divided into three age groups: 3-5 years old, 6-9 years old and over 10 years old. Each animal was characterized using 40 morphometric measurements. Discriminant analysis proved the exterior differences of mares in terms of the analysed metric values. It was concluded that the morphotype of modern Polish Konik mares is statistically significantly influenced by the following traits: neck ventral length, forearm circumference, distance between the vascular notch (incisura vasorum facialium) and the oral angle (angulus oris), distance between the margo coronalis ungulae and the margo solearis ungulae of the thoracic limb, thorax circumference and pelvis width...
