哺乳动物SWI/SNF(mSWI/SNF，也称为BAF)复合体的亚单位最近被认为是一种肿瘤抑制因子，与许多人类恶性肿瘤有关。为了全面了解它们的参与程度，我们对纯化的内源性mSWI/SNF复合体进行了蛋白质组学分析。我们的研究揭示了在酵母SWI/SNF复合体中没有发现的几个新的专门的、稳定的亚基，包括Bcl7a、b和c、BCL11a和b、Brd9和SS18。结合这些新成员，我们在最近的人类原发肿瘤外显子组和全基因组测序研究中确定了mSWI/SNF亚单位突变的频率。令人惊讶的是，在44项外显子组测序研究中，19.6%的人类肿瘤报告了mSWI/SNF亚单位的突变。我们的分析表明，特定的亚单位可以预防特定组织中的癌症。此外，我们发现一个以上亚基的突变在某些癌症中很常见，我们将其定义为一种复合杂合性。我们的研究表明，mSWI/SNF是人类癌症中最常见的突变染色质调节复合体(CRC)，与其他已知的肿瘤抑制因子和癌基因不同，mSWI/SNF广泛突变，类似于TP53。因此，这些多态的染色质调节复合体的正常功能可能构成了人类肿瘤抑制的主要机制。
Subunits of mammalian SWI/SNF (mSWI/SNF, also called BAF) complexes have recently been implicated as tumor suppressors in a number of human malignancies. To understand the full extent of their involvement, we conducted a proteomic analysis of purified endogenous mSWI/SNF complexes. Our studies revealed several new dedicated, stable subunits not found in the yeast SWI/SNF complex including Bcl7a, b and c, Bcl11a and b, Brd9 and SS18. Incorporating these novel members, we determined the frequency of mSWI/SNF subunit mutations in recent exome- and whole-genome sequencing studies of primary human tumors. Surprisingly, mSWI/SNF subunits are mutated in 19.6% of all human tumors reported in 44 exome sequencing studies. Our analysis suggests that specific subunits protect against cancer in specific tissues. In addition, we find that mutations to more than one subunit, which we define as a type of compound heterozygosity, are prevalent in certain cancers. Our studies demonstrate that mSWI/SNF is the most frequently mutated chromatin-regulatory complex (CRC) in human cancer and that in contrast to other known tumor suppressors and oncogenes surveyed, mSWI/SNF is broadly mutated, similar to TP53. Thus, proper functioning of these polymorphic chromatin regulatory complexes may constitute a major mechanism of human tumor suppression.
