Prognostic scores were built as a weighted sum of prognostic variables for each patient. The cohort comprised 1225 patients, with at least one gene mutation identified in 1177 patients (96%). Genomic factors associated with inferior outcomes included monosomy 7, del(5q), and GNAS and TP53 mutations for OS; trisomy 19, del(5q), monosomy 7, and GNAS, PTPN11 and TP53 mutations for LFS; and i(17q), del(5q), and NPM1, NRAS, GNAS, IDH2, SF3B1 and RUNX1 mutations for TTP-sAML. The Asian Prognostic Scoring System (APSS) was determined, stratifying patients into six prognostic risk categories. The APSS, compared with the International Prognostic Scoring System molecular (IPSS-M), showed superior concordance indices (C-indices) for OS (0.73 versus 0.57), LFS (0.72 versus 0.59), and TTP-sAML (0.75 versus 0.65) for this Asian cohort.

The transcription factor SOX11 is aberrantly expressed in conventional aggressive MCL, while it is not or weakly expressed in the leukemic non-nodal MCL subtype with a predominantly indolent clinical evolution. SOX11 is a key driver of MCL through the regulation of several oncogenic mechanisms, suggesting that it may be interacting with different protein complexes to exert its multiple actions. Using proteomic strategies, we characterized the SOX11-interactome and validated its physical interaction with SMARCA4, the catalytic subunit of the SWI/SNF chromatin-remodeling complex. <i>SMARCA4</i> expression is directly regulated by SOX11, and its upregulation significantly associates with worse outcomes of patients. Integration of global DNA-binding and transcriptomic profiles revealed that SOX11 and SMARCA4 share binding sites enriched in open chromatin and active promoters and regulate common key oncogenic pathways crucial for MCL progression and aggressiveness. The SMARCA4-specific PROTAC-degrader AU-15330 significantly reduced SOX11 binding to specific regulatory regions and diminished the activation of BCR-, NIK-, and BCL2-signaling pathways.

To identify prognostic biomarkers in PT-DLBCL, in this study we analyzed DNA and RNA samples of PT-DLBCL tumors from 206 patients using next-generation sequencing platforms and assays. Genetic alteration analysis found that multiple chromosomal copy number variations (CNVs), <i>TP53</i> transcript mutations with high variant allele frequency, and MCD subtype had significantly adverse prognostic effects, whereas elevated microsatellite instability had a significantly favorable prognostic effect in PT-DLBCL. Targeted RNA-seq analysis identified a PTL gene expression signature by comparing PT-DLBCL with systemic DLBCL and revealed the heterogeneity within PT-DLBCL by unsupervised clustering, which classified PT-DLBCLs into a testicular lymphoma tumor (TLT) subtype and a microenvironment (ME) subtype. The TLT subtype featured upregulation of genes functioning in DNA damage response, DNA repair, chromatin remodeling, the cell cycle, and the nucleus, and was associated with significantly poorer patient survival and higher frequencies of <i>MYD88</i> mutations, multiple CNVs, MCD subtype, bulk tumors, and elderly patients in the PT-DLBCL cohort. In contrast, the ME subtype distinctively featured upregulation of various signaling pathway genes involving the tumor microenvironment and downregulation of <i>BTK</i> and B-cell receptor signaling genes, and was associated with significantly better clinical outcome than the TLT subtype of PT-DLBCL independently of CNVs, MCD and <i>MYD88</i> mutation and than systemic DLBCL. Moreover, genomic microRNA profiling analysis identified a PTL microRNA signature significantly differentially expressed between PT-DLBCL and systemic DLBCL patients and within the PT-DLBCL cohort, and PT-DLBCL patients with higher expression of 16 PTL microRNAs (14 are testicular tissue-specific) had significantly better survival.
