High expression of HIF-2α and its anti-radiotherapy effect in lung cancer stem cells

J. C. Sun, He, F., Yi, W., Wan, M. H., Li, R., Wei, X., Wu, R., and Niu, D. L., “High expression of HIF-2α and its anti-radiotherapy effect in lung cancer stem cells”, vol. 14, pp. 18110-18120, 2015.

Hypoxia-inducible factor-2 alpha (HIF-2α) has been shown to regulate cell stemness, although the expression and effects of HIF-2α in lung cancer stem cells remained unclear. This study investigated HIF-2α expression in lung cancer stem cells, as well as the relationship between HIF-2α expression and radioresistance in lung cancer cells. Stem-like cells (CD133+) in the non-small-cell lung cancer cell line A549 were enriched by serum-free culture conditions, and CD133+ cells were sorted via fluorescence-activated cell sorting.

Performance of peanut mutants and their offspring generated from mixed high-energy particle field radiation and tissue culture

J. S. Wang, Qiao, L. X., Zhao, L. S., Wang, P., Guo, B. T., Liu, L. X., and Sui, J. M., “Performance of peanut mutants and their offspring generated from mixed high-energy particle field radiation and tissue culture”, vol. 14, pp. 10837-10848, 2015.

To develop new ways to breed peanut, we irradiated seeds of the Luhua 11 cultivar with a mixed high-energy particle field at different doses. The embryonic leaflets were extracted as explants and incubated on somatic embryo induction medium and then on somatic embryo germination and regeneration medium. After being grafted, the M1-generation plants were transplanted, and seeds from each M1-generation plant were harvested. In the following year, the M2-generation seeds were planted separately.
