Effect of Poly(methacrylic acid) on the Cytokine Level in an In Vivo Tumor Model.

Unlabelled: Cancer is a leading cause of mortality globally. Despite remarkable improvements in cancer-treatment approaches, disease recurrence and progression remain major obstacles to therapy. While chemotherapy is still a first-line treatment for a variety of cancers, the focus has shifted to the development and application of new approaches to therapy.

Insight into redox regulation of apoptosis in cancer cells with multiparametric live-cell microscopy.

Cellular redox status and the level of reactive oxygen species (ROS) are important regulators of apoptotic potential, playing a crucial role in the growth of cancer cell and their resistance to apoptosis. However, the relationships between the redox status and ROS production during apoptosis remain poorly explored. In this study, we present an investigation on the correlations between the production of ROS, the redox ratio FAD/NAD(P)H, the proportions of the reduced nicotinamide cofactors NADH and NADPH, and caspase-3 activity in cancer cells at the level of individual cells.

Immunopharmacological Properties of Methacrylic Acid Polymers as Potential Polymeric Carrier Constituents of Anticancer Drugs.

Cytostatic chemotherapeutics provide a classical means to treat cancer, but conventional treatments have not increased in efficacy in the past years, warranting a search for new approaches to therapy. The aim of the study was, therefore, to obtain methacrylic acid (MAA) (co)polymers and to study their immunopharmacological properties. 4-Cyano-4-[(dodecylsulfanylthiocarbonyl)sulfanyl] pentanoic acid (CDSPA) and 2-cyano-2-propyl dodecyl trithiocarbonate (CPDT) were used as reversible chain transfer agents.

FUCCI-Red: a single-color cell cycle indicator for fluorescence lifetime imaging.

The phase of the cell cycle determines numerous aspects of cancer cell behaviour including invasiveness, ability to migrate and responsiveness to cytotoxic drugs. To non-invasively monitor progression of cell cycle in vivo, a family of genetically encoded fluorescent indicators, FUCCI (fluorescent ubiquitination-based cell cycle indicator), has been developed. Existing versions of FUCCI are based on fluorescent proteins of two or more different colors fused to cell-cycle-dependent degradation motifs.
