DESCRIPTION: (Adapted from the Investigator's Abstract): Studies in this grant period will focus on the hypothesis that chronic hypersecretion of LH, with a significant contribution from FSH, causes tumor formation by altering expression of a complex network of genes including a progressive down-regulation of the LH receptors and an increase in cyclin D2. The investigators will also map and clone the three non-allelic variants in the CF-1 genome necessary for GC tumorigenesis and contribute to its complete penetrance. In identifying gene expression profiles unique to the formation of granulosa cell tumors, these studies should contribute to a better understanding of permissive and causative events that underlie tumor formation.

描述：（改编自研究者摘要）：本次资助的研究 本期将重点关注以下假设：LH 慢性分泌过多， FSH 的显着贡献，通过改变导致肿瘤形成 复杂的基因网络的表达，包括渐进的 LH 受体下调和细胞周期蛋白 D2 增加。这 研究人员还将绘制并克隆三个非等位基因变体 CF-1 基因组是 GC 肿瘤发生所必需的，并有助于其完整 外显率。在识别形成独特的基因表达谱时 颗粒细胞瘤，这些研究应该有助于更好地 了解肿瘤形成的许可事件和致病事件。
