question:
Phagocytes, especially monocytes, macrophages, and dendritic cells, play a pivotal role in the innate and adaptive immune responses during sepsis. We have shown that inhibition of histone deacetylase 6 improves survival and increases bacterial clearance in a mouse model of cecal ligation and puncture (CLP). The aim of this study was to determine whether this effect was associated with changes in the number and composition of different blood cell types in the circulation.', 'C57BL/6J mice were subjected to CLP, and 1\xa0h later given an intraperitoneal injection of either Tubastatin A dissolved in dimethyl sulfoxide, or dimethyl sulfoxide only. Sham-operated animals were treated in an identical fashion but not subjected to CLP. Forty-eight hours later, peripheral blood was obtained via cardiac puncture and analyzed using a HemaTrue veterinary hematology analyzer.', 'Tubastatin A administration increased the number of circulating monocytes in the sham-operated and the CLP animals. In comparison with the sham, CLP animals displayed an increase in the granulocyte percentage in white blood cells and decrease in the lymphocyte number and percentage, with a resultant increase in the granulocyte-to-lymphocyte ratio. Treatment of CLP animals with Tubastatin A decreased the granulocyte percentage and restored the lymphocyte number and percentage, which decreased the granulocyte-to-lymphocyte ratio. In the sham animals, Tubastatin A increased red blood cell number, hematocrit, and hemoglobin. This effect was not seen in CLP animals.

question:
ΔNp63, a splice variant of p63, is overexpressed and exhibits oncogenic activity in many cancers including pancreatic and breast cancer and promotes cell survival by inhibiting apoptosis. Despite its role in tumorigenesis, mechanistic activity of ΔNp63 mediated oncogenic function in osteosarcoma is poorly understood.', 'The expression levels of p63 isoforms in osteosarcoma cell lines were identified using quantitative techniques. Expression profiling using microarray, siRNA mediated loss-of-function, and chromatin immunoprecipitation assays were employed to identify novel ΔNp63α targets in p63-null osteosarcoma SaOS-2 cells that were engineered to express ΔNp63α. The phenotype of SaOS-2-ΔNp63α cells was assessed using wound-healing, colony formation, and proliferation assays.', 'The comparative expression analyses identified ΔNp63α as the predominant p63 isoform expressed by invasive OS cell lines. Phenotypic analyses of SaOS-2-ΔNp63α cells in vitro indicate that ΔNp63α imparted tumorigenic attributes upon tumor cells. Further, we show that in osteosarcoma cells ΔNp63α directly regulated the transcription factor GLI2, which is a component of the hedgehog signaling pathway, and that functional interactions between ΔNp63α and GLI2 confer oncogenic properties upon OS cells.

question:
Despite recent advances in prostate cancer diagnostics and therapeutics, the overall survival rate still remains low. This study was aimed to assess potential anti-cancer activity of maysin, a major flavonoid of corn silk (CS, Zea mays L.), in androgen-independent human prostate cancer cells (PC-3).', 'Maysin was isolated from CS of Kwangpyeongok, a Korean hybrid corn, via methanol extraction and preparative C18 reverse phase column chromatography. Maysin cytotoxicity was determined by either monitoring cell viability in various cancer cell lines by MTT assay or morphological changes. Apoptotic cell death was assessed by annexin V-FITC/PI double staining, depolarization of mitochondrial membrane potential (MMP), expression levels of Bcl-2 and pro-caspase-3 and by terminal transferase mediated dUTP-fluorescein nick end labeling (TUNEL) staining. Underlying mechanism in maysin-induced apoptosis of PC-3 cells was explored by evaluating its effects on Akt and ERK pathway.', 'Maysin dose-dependently reduced the PC-3 cell viability, with an 87% reduction at 200 μg/ml. Maysin treatment significantly induced apoptotic cell death, DNA fragmentation, depolarization of MMP, and reduction in Bcl-2 and pro-caspase-3 expression levels. Maysin also significantly attenuated phosphorylation of Akt and ERK. A combined treatment with maysin and other known anti-cancer agents, including 5-FU, etoposide, cisplatin, or camptothecin, synergistically enhanced PC-3 cell death.
