    • The landscape of genetic alterations in lung adenocarcinoma derived from Asian patients is largely uncharacterized. Here we present an integrated genomic and transcriptomic analysis of 335 primary lung adenocarcinomas and 35 corresponding lymph node metastases from Chinese patients. Altogether 13 significantly mutated genes are identified, including the most commonly mutated gene TP53 and novel mutation targets such as RHPN2, GLI3 and MRC2. TP53 mutations are furthermore significantly enriched in tumours from patients harbouring metastases. Genes regulating cytoskeleton remodelling processes are also frequently altered, especially in metastatic samples, of which the high expression level of IQGAP3 is identified as a marker for poor prognosis. Our study represents the first large-scale sequencing effort on lung adenocarcinoma in Asian patients and provides a comprehensive mutational landscape for both primary and metastatic tumours. This may thus form a basis for personalized medical care and shed light on the molecular pathogenesis of metastatic lung adenocarcinoma.

    • Both somatic hypermutation (SHM) and class switch recombination (CSR) are initiated by activation-induced cytidine deaminase (AID). Dysregulation of these processes has been linked to B cell lymphomagenesis. Here we performed an in-depth analysis of diffuse large B cell lymphoma (DLBCL) and follicular lymphoma (FL) genomes. We characterized seven genomic mutational signatures, including two B cell tumor-specific signatures, one of which is novel and associated with aberrant SHM. We further identified two major mutational signatures (K1 and K2) of clustered mutations (kataegis) resulting from the activities of AID or error-prone DNA polymerase η, respectively. K1 was associated with the immunoglobulin (Ig) switch region mutations/translocations and the ABC subtype of DLBCL, whereas K2 was related to the Ig variable region mutations and the GCB subtype of DLBCL and FL. Similar patterns were also observed in chronic lymphocytic leukemia subtypes. Thus, alterations associated with aberrant CSR and SHM activities can be linked to distinct developmental paths for different subtypes of B cell lymphomas.
