To explore the therapeutic potential of direct PP2A activation in a diverse set of MYC-driven cancers, here we used biochemical assays, recombinant cell lines, gene expression analyses, and immunohistochemistry to evaluate a series of first-in-class small-molecule activators of PP2A (SMAPs) in Burkitt lymphoma, KRAS-driven non-small cell lung cancer, and triple-negative breast cancer.

Strikingly, we did not detect recurrent mutations in genes of the ID3-TCF3 axis or the SWI/SNF complex that are frequently altered in BL, or in genes frequently mutated in germinal center-derived B-cell lymphomas like <i>KMT2D</i> or <i>CREBBP</i> An exception is <i>GNA13</i>, which was mutated in 7 of 15 cases.
In addition, PAC-1 was probably known to be associated with Burkitt Lymphoma (Odds Ratio [OR] 6.67, Relative Risk [RR] 3.13, 95% CI 1.06-9.21; p = 0.02).
To explore whether disruption of the MYC-WDR5 interaction could potentially become a viable anticancer strategy, we developed a Burkitt's lymphoma system that allows replacement of wild-type MYC for mutants that are defective for WDR5 binding or all known nuclear MYC functions.
In the present study, we found that compared with cell lines generated from diffuse large-B-cell lymphoma (DLBCL) patients, cell lines with features of Burkitt lymphoma have higher levels of HXKII because of the activation of both c-MYC and HIF-1.

Here we show that interferon regulatory factor 4 (IRF4), another plasma cell transcription factor that is either not expressed or expressed at a low level in EBV-positive Burkitt's lymphoma (BL) cells, can activate the promoters of EBV Zta and RTA, but is not sufficient to elicit EBV lytic reactivation in latently infected BL cells.
We investigated the cytolytic and mechanistic activity of anti-CD19 chimeric antigen receptor natural killer (CD19.CAR.NK92) therapy in lymphoma cell lines (diffuse large B-cell, follicular, and Burkitt lymphoma), including rituximab- and obinutuzumab-resistant cells, patient-derived cells, and a human xenograft model.
In Burkitt lymphoma cells, miR-150 expression was significantly lower than normal ones, whereas the expression of LMO4 was upregulated. miR-150 might inhibit cell proliferation and promoted apoptosis in Burkitt lymphoma deterioration by downregulating LMO4.

Treatment of Burkitt lymphoma cell lines with a specific inhibitor indicates that decreased GCN5 HAT activity reduces viability and proliferation of these cells.

We identified 76 genes essential to Burkitt lymphoma, including genes associated with hematopoietic cell differentiation (<i>FLI1, BCL11A</i>) or B-cell development and activation (<i>PAX5, CDKN1B, JAK2, CARD11</i>) and found a number of context-specific dependencies including oncogene addiction in cell lines with <i>TCF3</i>/<i>ID3</i> or <i>MYD88</i> mutation.
