Cytochalasin B inhibits the proliferation of human glioma U251 cells through cell cycle arrest and apoptosis

Z. G. Tong, Liu, N., Song, H. S., Li, J. Q., Jiang, J., Zhu, J. Y., and Qi, J. P., Cytochalasin B inhibits the proliferation of human glioma U251 cells through cell cycle arrest and apoptosis, vol. 13, pp. 10811-10822, 2014.

Cytochalasin B (CB) is known to inhibit a number of cancer types, but its effects on gliomas are unknown. We examined the in vitro effects of CB on the proliferation of human glioma U251 cells, as well as determined its mechanism of action. Cell proliferation was determined using CCK-8. The effect of CB on U251 cell morphology was observed under a transmission electron microscope. Cell cycle distribution was assessed using propidium iodine and Giemsa staining, and cell apoptosis was determined by annexin V-fluorescein isothiocyanate/propidium iodide.

Mitotic and meiotic behavior of rye chromosomes in wheat - Psathyrostachys huashanica amphiploid x triticale progeny

Q. Xie, Kang, H., Sparkes, D. L., Tao, S., Fan, X. M., Xu, L., Fan, X., Sha, L., Zhang, H., Wang, Y., Zeng, J., and Zhou, Y., Mitotic and meiotic behavior of rye chromosomes in wheat - Psathyrostachys huashanica amphiploid x triticale progeny, vol. 12, pp. 2537-2548, 2013.

The dynamics of rye chromosomes during mitosis and meiosis was analyzed in a subset comprising 33 F3 lines from the cross of wheat, Psathyrostachys huashanica amphiploid (AABBDDNsNs) and hexaploid triticale (AABBRR), as visualized by genomic in situ hybridization. The results indicated that 31 of the total lines contained 4-14 rye chromosomes. Twenty-eight combinations had more rye chromosomes than the F1 hybrids, suggesting the occurrence of spontaneous quantitative increment. No P.

Mitotic behavior in root tips of Brachiaria genotypes with meiotic chromosome elimination during microsporogenesis

M. F. Felismino, Silva, N., Pagliarini, M. S., and Valle, C. B., Mitotic behavior in root tips of Brachiaria genotypes with meiotic chromosome elimination during microsporogenesis, vol. 7, pp. 336-341, 2008.

Three accessions of Brachiaria brizantha, three of B. humidicola, and two interspecific hybrids between B. ruziziensis and B. brizantha were analyzed with regard to their mitotic behavior in root tips. All these genotypes revealed chromosome elimination or lack of chromosome affinity in previous analyses of microsporogenesis. Analyses of root tips showed a normal mitotic division in all accessions and hybrids, reinforcing the notion that the genetic control of meiosis is totally independent of that of mitosis.
