Abstract
BACKGROUND/AIM Oncolytic adenoviruses are promising therapeutic agents against both the bulk of tumor cells and cancer stem cells. The present study intended to test the oncolytic capability of adenovirus serotype 6 (Ad6), which has a lower seroprevalence and hepatotoxicity relatively to adenovirus 5 (Ad5), against the glioblastoma and its cancer stem cells. MATERIALS AND METHODS Oncolytic efficacy of Ad6 was compared to widespread Ad5 both in vitro and in vivo, using the U87 and U251 human glioblastoma cell lines and subcutaneously transplanted U87 cells in SCID mice, respectively. RESULTS Ad6 had a dose-dependent cytotoxicity toward glioblastoma cells in vitro and its intratumoral injections lead to a significant (p<0.05) decrease in volume of U87 xenografts, similarly to Ad5. Based on the innate capability of glioblastoma cancer stem cells to internalize a fluorescent-labeled double-stranded DNA probe, the spatial localization of these cells was estimated and it was shown that the number of cancer stem cells tended to decrease under adenovirus therapy as compared to the control group. CONCLUSION Ad6 was shown to be a promising agent for treating glioblastomas.

Abstract
Murine Krebs-2 tumor-initiating stem cells are known to natively internalize extracellular double-stranded DNA fragments. Being internalized, these fragments interfere in the repair of chemically induced interstrand cross-links. In the current investigation, 756 bp polymerase chain reaction (PCR) product containing bulky photoreactive dC adduct was used as extracellular DNA. This adduct was shown to inhibit the cellular system of nucleotide excision repair while being resistant to excision by this DNA repair system. The basic parameters for this DNA probe internalization by the murine Krebs-2 tumor cells were characterized. Being incubated under regular conditions (60 min, 24°C, 500 μL of the incubation medium, in the dark), 0.35% ± 0.18% of the Krebs-2 ascites cells were shown to natively internalize modified DNA. The saturating amount of the modified DNA was detected to be 0.37 μg per 106 cells. For the similar unmodified DNA fragments, this ratio is 0.73 μg per 106 cells. Krebs-2 tumor cells were shown to be saturated internalizing either (190 ± 40) × 103 molecules of modified DNA or (1,000 ± 100) × 103 molecules of native DNA. On internalization, the fragments of DNA undergo partial and nonuniform hydrolysis of 3' ends followed by circularization. The degree of hydrolysis, assessed by sequencing of several clones with the insertion of specific PCR product, was 30-60 nucleotides.

Abstract
The present study demonstrates that monocyte-derived dendritic cells (moDCs) produced in vitro using a GM-CSF and IFN-α differentiation protocol encompass a rare (∼5%) subpopulation of cells showing classical dendritic cell morphology and capable of natural internalization of extracellular self-DNA. We established that DEFB, HMGB1, LL-37 and RAGE antigens, which mediate the process of DNA internalization, are expressed on the surface of moDCs similar to plasmacytoid dendritic cells. However, in constrast to the latter subpopulation, these cells do not produce interleukin (IL)-37. Nonetheless, the process of DNA internalization was not in direct relation to the presence of the above antigens on the surface of these cells. Dendritic cells were sorted into total and non-DNA-internalizing populations and cytokine production was analyzed at 24-48 hours post-DNA treatment. We show that massive secretion of cytokines by dendritic cells is associated with the dsDNA-internalizing subpopulation. A total pool of IFN-moDCs secrete pro-inflammatory "first-wave" cytokines (IL-2, IL-6, IL-8, TNF-α) at both 24 and 48 hours time points. The anti-inflammatory cytokines IL-4 and IL-10 were found to be modestly induced, whereas GM-CSF, G-CSF, and IFN-γ production was strongly induced. Treatment of moDCs with dsDNA results in the up-regulated transcription of IFN-α, IFN-β, IFN-γ, IL-8, IL-10, and VEGF by 6 hours. Combined dsDNA + chloroquine treatment has a synergistic effect on transcription of only one of the genes tested, with the pro-inflammatory cytokine IFN-β displaying the strongest fold induction by 24 hours.

Abstract
Krebs-2 solid carcinoma was cured using a new “3+1” strategy for eradication of Krebs-2 tumor-initiating stem cells. This strategy was based on synchronization of these cells in a treatment-sensitive phase of the cell cycle. The synchronization mechanism, subsequent destruction of Krebs-2 tumor-initiating stem cells, and cure of mice from a solid graft were found to depend on the temporal profile of the interstrand cross-link repair cycle. Also, the temporal profile of the Krebs-2 interstrand repair cycle was found to have a pronounced seasonal cyclicity at the place of experiments (Novosibirsk, Russia). As a result, the therapeutic effect that is based on application of the described strategy, originally developed for the “winter repair cycle” (November−April), is completely eliminated in the summer period (June−September). We conclude that оne of the possible and the likeliest reasons for our failure to observe the therapeutic effects was the seasonal cyclicity in the duration of the interstrand repair cycle, the parameter that is central to our strategy.

Abstract
Using the ability of poorly differentiated cells to natively internalize fragments of extracellular double-stranded DNA as a marker, we isolated a tumorigenic subpopulation present in Krebs-2 ascites that demonstrated the features of tumor-inducing cancer stem cells. Having combined TAMRA-labeled DNA probe and the power of RNA-seq technology, we identified a set of 168 genes specifically expressed in TAMRA-positive cells (tumor-initiating stem cells), these genes remaining silent in TAMRA-negative cancer cells. TAMRA+ cells displayed gene expression signatures characteristic of both stem cells and cancer cells. The observed expression differences between TAMRA+ and TAMRA- cells were validated by Real Time PCR. The results obtained corroborated the biological data that TAMRA+ murine Krebs-2 tumor cells are tumor-initiating stem cells. The approach developed can be applied to profile any poorly differentiated cell types that are capable of immanent internalization of double-stranded DNA.
