肿瘤靶向治疗基因检测临床应用结果

染色体缺失在癌症中确实比比皆是，并且在某些区域以非随机方式检测到。尽管它们的相关性仍然难以捉摸，但普遍认为节段性损失为细胞提供了选择性生长优势。因此，这些可能包含控制正常生长和抑制恶性肿瘤的基因和/或调节序列。《基因解码创新技术团队》开发了一种基于单染色体杂合体的实验模型，用于基因检测中缺失的产生和功能分析，称为“消除测试”（Et）。专注于人类 3 号染色体——已知它携带多个 3p 缺失——预计 Et 将 3p 肿瘤抑制区域限制在一个足够小的片段上，从而允许选择一个至关重要的候选基因。令人惊讶的是，基因解码创新技术团队检测到三个区域在全部或大部分肿瘤中丢失：CER1 (3p21.3, Mb: 43.32-45.74)、CER2 (3p22, Mb: 37.83-39.06) 和 FER (3p14.3-p21.2, mb：50.12-58.03）。相比之下，定期保留 3q26-qter 区域 (CRR)。 CER1 - 基因解码创新技术团队的主要关注点 - 包含多个可能抑制肿瘤生长的基因，但 RIS1、LF (LTF) 和 LIMD1 这 3 个基因已经获得了必要的实验支持，被认为是真正的肿瘤抑制因子。肿瘤抑制区域边界显示出不稳定特征，包括：（1）它们在进化和肿瘤中断裂，（2）它们水平进化，（3）它们富含假基因插入。断点簇区域贼显着的特征是驱动水平进化并导致癌症相关不稳定性的节段性重复。

肿瘤发生与反复转移国际数据库描述：

Chromosome deletions do abound in cancer and are detected in certain regions in a non-random manner. Although their relevance remains elusive, it is a general agreement that segmental losses provide the cell with selective growth advantage. Consequently these may contain genes and/or regulatory sequences that control normal growth and inhibit malignancy. We have developed a monochromosomal hybrid based experimental model for the generation and functional analysis of deletions, that is called "elimination test" (Et). Focused on human chromosome 3 - that was known to carry multiple 3p deletions - the Et was expected to restrict a 3p tumor suppressor region to a sufficiently small segment that permits the selection of a critically important candidate gene. Surprisingly, we detected three regions that were lost in all or majority of tumors: CER1 (3p21.3, Mb: 43.32-45.74), CER2 (3p22, Mb: 37.83-39.06) and FER (3p14.3-p21.2, Mb: 50.12-58.03). In contrast a 3q26-qter region (CRR) was regularly retained. CER1 - our main focus - contains multiple genes that may inhibit tumor growth, but 3 genes, RIS1, LF (LTF) and LIMD1 have already the necessary experimental support to be considered bona fide tumor suppressors. Tumor suppressor region borders display instability features including: (1) they break in evolution and in tumors, (2) they evolve horizontally, and (3) they are enriched with pseudogene insertions. The most remarkable features at the breakpoint cluster regions were segmental duplications that drive horizontal evolution and contribute to cancer associated instability.
