Article Title: Hydrophilic and Lipophilic Carbon Dots Impart Thermosensitivity to Doxorubicin Loaded Phospholipid Liposomes

doi: 10.3390/ph19050668

Figure Lengend Snippet: Comparative cytotoxicity of either empty or DOX-loaded PEGylated DPPC liposomes (Lip), or CD (Lip-CD) and CD-C16 (Lip-CD16) containing liposomes against PC3 cells following an 1 h incubation at ( A ) 37 or ( B ) 40°C. DOX concentration was 5 or 10 μM, while the concentration of empty liposomes corresponded to the liposomal concentration in experiments at the highest DOX concentration (10 μΜ). The cytotoxicity was assessed after a 24 h post-incubation period employing the standard MTT assay. Cell survival data are the mean of at least six independent values while error bars represent one standard deviation. The statistical significance was derived by Student’s t -test following the assignment: * p < 0.05, ** p < 0.01, *** p < 0.001; ns denotes no statistical significance, p > 0.05.

Article Snippet: The human prostate cancer PC3 cell line as well as the non-cancerous human embryonic kidney HEK293 of the cell bank from the Institute of Nanoscience and Nanotechnology, NCSR Demokritos, were purchased from the American Type Culture Collection (ATCC CRL-1435TM and CRL-1573TM, respectively; Manassas, VA, USA).

Article Title: Dynamic optimization of extrachromosomal DNA copy number drives tumour evolution

doi: 10.64898/2026.03.20.713026

Figure Lengend Snippet: (a) Schematics depicting hypothesized ecDNA copy number distributions of all cells, G1 cells, and parent cells giving rise to daughter cells (left). Representative images from combined IF for Aurora B Kinase and Cyclin A and DNA FISH for MYC in COLO 320DM. Cyclin A was used as a marker to identify G1 interphase cells, whose copy number should theoretically be 1n before entering S-phase and undergoing genome doubling. Aurora B Kinase was used as an identification marker for recently divided daughter cells. Copy number of parents of daughter cells was estimated by taking the average of the daughter cells’ MYC DNA FISH foci areas. Copy numbers of parent cells were compared against copy numbers of G1 interphase cells to avoid high copy number bias arising from cells past S-phase and with replicated DNA content. Scale bars, 10 µm (right). (b) Histograms depicting proportion of G1 interphase and parent cells in each copy number quintile in COLO 320DM and PC3 DM.

Article Snippet: COLO 320DM and COLO 320HSR (colorectal cancer) and the parental PC3 (prostate cancer) cell lines were obtained from ATCC.

Techniques: Marker
