Molecular combing is a powerful and simple method for aligning DNA molecules onto a surface. Using this technique combined with fluorescence microscopy, we observed that the length of lambda-DNA molecules was extended to about 1.6 times their contour length (unextended length, 16.2 microm) by the combing method on hydrophobic polymethylmetacrylate coated surfaces. The effects of sodium and magnesium ions and pH of the DNA solution were investigated. Interestingly, we observed force-induced melting of single DNA molecules.

Oncogenic Human Papillomaviruses Drive One-Third of Sinonasal Squamous Cell Carcinoma and Are Not Mutually Exclusive for Gene Mutations.

Departement de Pathologie, Centre Hospitalo-Universitaire Montpellier, Montpellier, France.
Background: The detection rate of oncogenic human papillomaviruses (HPVs) in sinonasal squamous cell carcinomas (SNSCCs) varies among studies. The mutational landscape of SNSCCs remains poorly investigated.
Methods: We investigated the prevalence and prognostic significance of HPV infections based on p16 protein expression, HPV-DNA detection, and E6/E7 mRNA expression using immunohistochemistry, polymerase chain reaction, and in situ hybridization, respectively.
