Regulation of JAK2 kinase in lymphoma.
The Janus kinase 2 (JAK2)/signal transducers and activators of transcription (STAT) pathway play an important role in the pathogenesis of hematological malignancies. We have demonstrated that signaling through JAK2 and STAT3 is found active in more than 50% of lymphoma patients; and that inhibition of pathway by JAK2 inhibitor, TG101348 (TG) induces growth inhibition and apoptosis in a variety of lymphoma cell lines and patient samples. Studying 3 different scenarios of JAK/STAT signaling in NHL we have identified: 1) Genetic variations in JAK2 and STAT3 genes that led to identification of novel point mutations in JAK2and STAT3in DLBCL. 2) negative regulators of the STAT pathway - Suppressors of cytokine signaling (SOCS1) and protein tyrosine phosphatases (SHP1) found suppressed in 33% and 86% of DLBCL samples, respectively; and we have defined epigenetic mechanisms of silencing of PTPN6 (SHP1) in NHL and, 3) JAK/STAT pathway-specific cytokines (IL-2, IL-6, IL-10 and EGF) in serum samples from patients with DLBCL and revealed that enhanced serum levels of IL-10 contributes towards JAK2 activation; and that JAK2 inhibition with inhibitor, TG101348 inhibits autocrine production of IL-10 in DLBCL cells. These preclinical data provide the rationale to test JAK2 inhibitors in relapsed lymphoma cases. Since these agents have been already tested in clinical trials for myeloproliferative neoplasms, issues of their safety and clinical activity are partially addressed. We have proposed a trial design that will test the hypothesis that patient pre-selection based on tumor cell STAT3 activation status will improve the clinical outcome.
Epigenetic modulation through HDACs and long non-coding RNAs.
Epigenetic processes control normal embryonic development and growth; however, deregulated epigenetic processes also found in diseases such as cancer. As components of several multi-protein complexes, Class I HDACs such as HDAC1-3 are ubiquitously expressed nuclear enzymes regulating numerous cellular processes. Genetic ablation studies have shown that class I HDACs are involved in cell proliferation and survival; moreover, recently we have shown that HDAC3 can physically associate with STAT3 and directly regulates STAT3 activation in the diffuse large B cells. We have also reported that histone deacetylase inhibitors (HDACi), such as panobinostat (LBH589) by blocking Akt activity can synergize antitumor activity of mTOR inhibitors. The epigenome can mark DNA in two ways, both of which play a role in turning genes off or on. We have recently uncovered that lack of SHP1 a tumor suppressor gene found silenced in majority of DLBCL patients is associated with DNA hypermethylation at CpG2 sites in the promoter region of the gene. I have also discovered novel lncRNAs ROR1-AS1 overexpressed in mantle cell lymphoma and play an epigenetic role through PRC2 and EZH2. Moreover we have also shown role of GAS5 lncRNA in the MYC translation.
