| 1 | Mouse embryos cloned from brain tumors显示文摘Cancer cells escape from growth cont rol by accumulating genetic and epig enetic alterations.In rare instances,epigenetic changes alone are oncogenic.Furthermore,a gents that modify DNA methylation or chromatin structure can restore a normal phenotype to cells harboring oncogenic mutations.How ever,it is unclear to what extent epi genetic reprogramming can reverse o ncogenesis.Using somatic nuclear transfer,we show that medul loblastomas arising in Ptc1+/-mice can direct preimplantation develop ment.Additionally,blastocysts derived from medullobl astoma nuclei form postimplantatio n embryos with typical cell layers.T hus,tumor cells can be epigenetically reprogrammed into n ormal cell types.This approach coul d lead to a general strategy for assessing genetic and epigenetic contributions to tumorigenesis. | Li L Connelly MC Wetmore C Curran T Morgan JI | 2003 | 癌症2003，22，7： | 11 |
| 2 | Archaeological records of Dadiwan in the past 60 ka and the origin of millet agriculture显示文摘This paper reports the recent excavation of Unit Dadiwan06 at the Dadiwan site in Qin’an County, Gansu.A 65 ka chronological framework is established for Dadiwan06 on the basis of absolute dating (AMS 14C and OSL), stratigraphy, climate change events and archaeology.Artifact distributions reveal patterns of human behavioral variation and adaptation over the past 60 ka, from primitive hunting and gathering to advanced hunting and gathering, to primitive Neolithic agriculture, and finally to advanced Neolithic agriculture. | ZHANG DongJu CHEN FaHu BETTINGER R L BARTON L JI DuXue MORGAN C WANG Hui CHENG XiaoZhong DONG GuangHui GUILDERSON T P ZHAO Hui | 2010 | Chinese Science Bulletin2010，55，16： | 6 |
