We described a reference measurement procedure for amino acid (AA) quantification in blood samples based on deproteinization with 5-sulfosalicylic acid (SSA) and an isotope dilution-ultra performance liquid chromatography-tandem mass spectrometry (LC-MS) method. The serum was deproteinized with 15% v/v SSA and the supernatant was injected directly into the LC-MS system without further processing. Compared with the use of other precipitants and water as a control, five model AAs-valine, isoleucine, leucine, tyrosine, and phenylalanine-in the SSA-treated samples showed ionization enhancement as well as stable background signals without significant ion suppression effects...

The relative contribution of the effector molecules produced by T cells to tumour rejection is unclear, but interferon-γ (IFNγ) is critical in most of the analysed models. Although IFNγ can impede tumour growth by acting directly on cancer cells, it must also act on the tumour stroma for effective rejection of large, established tumours. However, which stroma cells respond to IFNγ and by which mechanism IFNγ contributes to tumour rejection through stromal targeting have remained unknown. Here we use a model of IFNγ induction and an IFNγ-GFP fusion protein in large, vascularized tumours growing in mice that express the IFNγ receptor exclusively in defined cell types...

REVIEW
Navid Koleini, Elissavet Kardami
Doxorubicin (Dox) is a cytotoxic drug widely incorporated in various chemotherapy protocols. Severe side effects such as cardiotoxicity, however, limit Dox application. Mechanisms by which Dox promotes cardiac damage and cardiomyocyte cell death have been investigated extensively, but a definitive picture has yet to emerge. Autophagy, regarded generally as a protective mechanism that maintains cell viability by recycling unwanted and damaged cellular constituents, is nevertheless subject to dysregulation having detrimental effects for the cell...
