Analysis of three large B-cell lymphoma cell lines treated with the histone deacetylase inhibitor panobinostat, hypomethylating agent decitabine, or both for 48hrs. Panobinostat synergizes with decitabine in DLBCL cells. Results provide insight into the molecular basis for this synergistic effect.

(Submitter supplied) Diffuse large B-cell lymphoma (DLBCL) is the most common type of lymphoid neoplasm in the world representing 30-40% of all lymphomas. Standard immunochemotherapy (cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab) ensures cure in 60 to 65% of patients, while the rest progress or relapse. While advances have been made in the treatment of DLBCL, especially with the addition of rituximab, it is now apparent that there may be significant differences in prognosis that are related to the cell of origin, and that this disease is heterogeneous and novel treatment options are needed. more...

(Submitter supplied) We demonstrate that the combination of the HDAC inhibitor, romidepsin, and the demethylating agent, azacitidine, exerts synergistic anti-proliferative effects and induction of apoptosis involving activation of the caspase cascade in CTCL cell lines as well as CD4+ T cells derived from patients with Sézary Syndrome (SS) with high tumor burden. We identified genes that were selectively induced by the combination treatment, such the tumor suppressor gene RhoB.

(Submitter supplied) Esophageal cancers (ECs) are highly aggressive tumors with poor prognosis and few treatment options. This study investigated the possibility of treating esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC) cells by inhibitors of broad and specific histone deacetylases (HDACi; SAHA, MS-275, FK228) and/or of DNMT (Azacytidine, AZA). Drug targets (HDAC1,2,3 and DNMT1) were present in non-neoplastic (HET-1A), ESCC (OE21) and EAC (OE33) cell lines. more...

(Submitter supplied) Pediatric AML cell lines (MV4;11, AML-193 and THP-1) were treated with DNA hypomethylating agent (azacytidine) and a pan histone deactylase inhibitor (panobinostat) alone or in combination. Treatment of AML cell lines with these epigenetic drugs synergistically suppresses cell viability in vitro and in xenograft models in vivo. Data show differential regulation of gene expression in AML cell lines by epigenetic drugs at concentrations which retained cell viability at a minimum of 75% even in the combination treatment.

(Submitter supplied) Background: In high-grade serous ovarian cancer (HGSOC) intrinsic and/or acquired resistance against platinum-containing chemotherapy is a major obstacle for successful treatment. A low frequency of somatic mutations, but frequent epigenetic alterations including DNA methylation in HGSOC tumors, presents the cancer epigenome as a relevant target for innovative therapy. Patient-derived xenografts (PDXs) supposedly are good preclinical models for identifying novel drug targets. more...

(Submitter supplied) A characteristic feature of anaplastic large cell lymphoma (ALCL) is the significant reduction of the T-cell expression program despite its T-cell origin, a finding very similar to the loss of B-cell identity of classical Hodgkin lymphoma (cHL). Previously we demonstrated that epigenetic mechanisms are active in cHL to induce this peculiar phenotype. The results show that combined DNA demethylation and histone acetylation of T-cell lines induce an almost complete extinction of the T-cell phenotype, including the down-regulation of essential T-cell receptor signalling pathway genes such as CD3, LCK and ZAP70, as well as an up-regulation of ALCL-characteristic genes. more...

(Submitter supplied) MicroRNAs (miRs) are small non-coding RNAs that can function as tumor suppressor genes. We previously reported that miR-1 is among the most consistently down-regulated miRs in primary human prostate tumors. In this follow-up study, we further corroborated this finding in an independent dataset and made the novel observation that miR-1 expression is further reduced in distant metastasis and is a predictor of disease recurrence. more...

(Submitter supplied) BACKGROUND. Perineural invasion (PNI) is the dominant pathway for local invasion in prostate cancer. To date, only few studies have investigated the molecular differences between prostate tumors with PNI and those without it. METHODS. To evaluate the involvement of both microRNAs and protein-coding genes in PNI, we determined their genome-wide expression with a custom microRNA microarray and Affymetrix GeneChips in 50 prostate adenocarcinomas with PNI and 7 without it. more...

(Submitter supplied) Silencing of genes that suppress the malignant phenotype by DNA methylation spurred an interest in the clinical use of epigenetic reprogramming agents. Single therapy is unlikely to be curative in the context of a heterogeneous disease such as Diffuse Large B cell Lymphomas (DLBCL). The combination of DNA demethylating drugs could increase the chance to respond to classical and new treatments. We found that DLBCL cell lines respond heterogeneously to DNA demethylating agents. more...

(Submitter supplied) The prognosis of the patients with inoperable or advanced granulosa cell tumors (GCTs) is still poor, and therefore it is important to establish a novel treatment strategy. Here we investigated the in vitro effects of a histone deacetylase inhibitor, panobinostat (PS) on two GCT cell lines (KGN and COV434). GCT cell lines were found to be susceptible to PS treatment and it inhibited cell growth mainly by apoptosis. more...
