2013-06-30 00:28:12小児の散発性(sporadic)の甲状腺乳頭がんの二つの特徴
ひとつは、遺伝子の点変異(point mutation)の有病率よりも遺伝子の再構成(rearrangement)の有病率が多いこと。
もうひとつは放射線誘発がんに比べて遺伝子の再構成の有病率が低いこと。
遺伝子の再構成と点変異の不均衡が、異なった年齢での予後の違いの一部分を説明するかもしれない

端的にいえば、放射線被ばくは、発症者数を増やすだけでなく、遺伝子点変異(point mutation)と遺伝子再構成(rearrangement)の比率を変化させると考えました。@drsteppenwolf
2013-10-06 23:28:55単純に甲状腺等価線量が高い人ではREP/PTC再構成の頻度が高いと考えてはいけない。
LNT - Single-hit target theory から導かれることは『甲状腺の集団等価線量が同等なら発病者も同等』ということ。
