53BP1 is an important genome stability regulator, which protects cells against double-strand breaks. Following DNA damage, 53BP1 is rapidly recruited to sites of DNA breakage, along with other DNA damage response proteins, including Ճ-H2AX, MDC1, and BRCA1. The recruitment of 53BP1 requires a tandem Tudor fold which associates with methylated histones H3 and H4. It has already been determined that the majority of DNA damage response proteins are phosphorylated by ATM and/or ATR after DNA... -

우포늪은 창녕군 유어면, 이방면 및 대합면에 걸쳐 원시생태계를 유지하고 있는 국내 최대의 내륙습지이다. 낙동강 본류의 물이 소하천인 토평 천의 골짜기를 따라 거슬러 올라가면서 퇴적물이 쌓여 자연제방이 생기고 그 안쪽에 물의 일부가 남아서 우포, 목포, 사지포의 배후습지가 되었다. 우포도 홍수 때 낙동강물이 역류하면서 수심이 깊어지고 평소에는 낙동강으로 자연 배수되어 수 심이 낮아졌다 (박수영 등 2000). 우포늪은 1997 년 7월 26일 생태계보전지역 중 생태계특별보호 구역 (환경부고시 1997-66호)으로 지정되었으며... -
Clay의 분포율이 높은 지역보다 농도 분포가 낮았다. 퇴적물내 인의 존재형태별 농도분포는 Adsorbed-P가 7~58㎍/g, NAI-P가 13~411㎍/g, Apatite-P가 52~482㎍/g, Residual-P가 75~894㎍/g으로 조사되었다. 하상퇴적물의 중금속 농도분포는 Cd N.D.~0.44㎍/g, Cr 0.2~4.2㎍/g, Cu 1.6~20.7㎍/g, Hg 1.4~78.0ng/g, Pb 2.1~18.9㎍/g, Zn 1.8~99.5㎍/g로 검출되었으나, 용출시험 결과로 미루어보면 용출 등으로 인한 영향은 미미할 것으로 판단된다. 5개 지점의 퇴적물을 대상으로 공기주입 및 공기미주입에 의한 용출 실험에서 중금속과...
