(Submitter supplied) Primary effusion lymphoma (PEL) is an aggressive subtype of non-Hodgkin lymphoma caused by Kaposi's sarcoma-associated herpesvirus (KSHV) infection. Currently, treatment options for patients with PEL are limited. Oncolytic viruses have been engineered as anticancer agents and have recently shown increased therapeutic promise. Similarly, lytic activation of endogenous viruses from latently infected tumor cells can also be applied as a cancer therapy. more...

(Submitter supplied) Primary effusion lymphoma (PEL) is an aggressive subtype of non-Hodgkin lymphoma caused by Kaposi’s sarcoma-associated herpesvirus infection, which is most commonly seen in HIV-positive patients. Induction of HIV reactivation by external stimuli in the presence of highly active anti-retroviral therapy (HAART) has been examined for its efficacy to eradicate latently infected HIV. Similary, lytic activation of viruses from latently infected tumor cells with anti-cancer drugs represents an effective strategy of anti-neoplastic therapy, through the induction of oncolysis by viral replication, stimulation of immune responses to the viral lytic antigens, and intrinsic effects of cancer drugs. more...

(Submitter supplied) KSHV is a principal causative agent of primary effusion lymphoma (PEL) which is lacking of effective treatment. Our previous data have showed that HGF/c-MET pathway is highly active within KSHV+ PEL cells and plays important role in tumor cell survival/growth. By using microarray analysis, we have identified the global gene profile controlled by HGF/c-MET pathway within KSHV+ PEL cell-lines and several novel “druggable” candidates closely related to cancer cell survival/growth, including ribonucleotide reductase (RR). more...

(Submitter supplied) Cereblon (CRBN), a substrate receptor of the E3 ubiquitin ligase complex CRL4CRBN, is the target of the immunomodulatory drugs lenalidomide and pomalidomide. Recently, it was demonstrated that binding of these drugs to CRBN promotes the ubiquitination and subsequent degradation of two common substrates, transcription factors Aiolos and Ikaros. Here we report that the pleiotropic pathway modifier CC-122, a new chemical entity termed pleiotropic pathway modifier binds CRBN and promotes degradation of Aiolos and Ikaros in diffuse large B-cell lymphoma (DLBCL) and T cells in vitro, in vivo and in patients, resulting in both cell autonomous as well as immunostimulatory effects. more...

(Submitter supplied) Ewing sarcomas (ES) are highly malignant, osteolytic bone or soft tissue tumors, which are characterized by early metastasis into lung and bone. Genetically, ES are defined by balanced chromosomal EWS/ETS translocations, which give rise to chimeric proteins (EWS-ETS) that generate an oncogenic transcriptional program associated with altered epigenetic marks throughout the genome. By use of an inhibitor (JQ1) blocking BET bromodomain binding proteins (BRDs) we strikingly observed a strong down-regulation of the predominant EWS-ETS protein EWS/FLI1 in a dose dependent manner. more...

(Submitter supplied) Ocular melanoma is a common primary malignant ocular tumor in adults with limited effective treatments, so novel therapeutic approaches are desperately needed. Epigenetic regulation plays an important role in tumor development. The SWI/SNF chromatin remodeling complex and bromodomain and extraterminal domain (BET) family proteins are epigenetic regulators involved in several cancers. We aimed to screen a candidate small molecule inhibitor targeting the SWI/SNF complex or BET proteins and investigate its effect and mechanism in ocular melanoma. more...

(Submitter supplied) Recent studies have demonstrated that the immunomodulatory drugs (IMiDs) lead to the degradation of the transcription factors Ikaros and Aiolos. However, why their loss subsequently leads to multiple myeloma (MM) cell death remains unclear. Using CRISPR-Cas9 genome editing, we have deleted IKZF1 and IKZF3 in human MM cell lines to gain further insight into their downstream gene regulatory networks. Our findings strongly support the central role of Ikaros and Aiolos in the action of the IMiDs. Inactivation of either factor alone recapitulates the cell intrinsic action of the IMiDs, resulting in cell cycle arrest and induction of apoptosis. Furthermore, evaluation of the transcriptional changes resulting from their loss demonstrates striking overlap with lenalidomide treatment.

(Submitter supplied) Primary effusion lymphoma (PEL), which is an aggressive lymphoma associated with Kaposi sarcoma-associated herpesvirus/human herpes virus-8 (KSHV/HHV-8), is refractory to standard chemotherapy, and exhibits a poor prognosis. Although PU.1 is down-regulated in PEL among B-cell transcription factors, the potential role of its reduction remains to be elucidated. In this investigation, we analyzed the DNA methylation of PU.1 cis-regulatory elements in PEL and the effect of restoring PU.1 on PEL cells. more...

(Submitter supplied) Two human acute lymphoblastic leukemia cell lines were treated with a BET bromodomain inhibitor that blocks BET association with chromatin. These cell lines, MHH-CALL4 and MUTZ-5, each carry translocation of the CRLF2 gene into the IgH locus, and their growth was found to be susceptible to BET inhibition. Gene expression changes were analyzed in each cell line versus vehicle control.
