In Vitro Effects of Boron-Containing Compounds upon Glioblastoma Cells

Experimental Biology and Medicine, 1997
Boron-neutron capture therapy (BNCT) is currently under investigation as a novel therapeutic modality for glioblastoma. This study was undertaken to determine whether boron-containing compounds 4-borono-2-fluoro-D,L-phenylalanine (FBPA) and FBPA-fructose have direct effects upon kinetics of A172, a glioblastoma cell line.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

Molecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.
