We investigated the pre-clinical activities of two novel histone deacetylase inhibitors (HDACi), ITF-A and ITF-B, in a large panel of pre-clinical lymphoma models. The two compounds showed a dose-dependent anti-proliferative activity in the majority of cell lines. Gene expression profiling (GEP) of diffuse large B-cell lymphoma (DLBCL) cells treated with the compounds showed a modulation of gen...

Histone deacetylase inhibitors (HDACi) are potential candidates for therapeutic approaches in cancer and neurodegenerative diseases such as spinal muscular atrophy (SMA)--a common autosomal recessive disorder and frequent cause of early childhood death. SMA is caused by homozygous absence of SMN1. Importantly, all SMA patients carry a nearly identical copy gene, SMN2, that produces only minor l...

The bone marrow microenvironment protects acute myeloid leukemia (AML) cells during chemotherapy and is a major factor in relapse. Here, we examined which type(s) of bone marrow cells are responsible for the relapse of AML following treatment with cytarabine (Ara-C), and we identified a means to inhibit this protection. To determine the protective cell type(s), AML cells were treated with Ara-C...

The unfolded protein response is responsible for the detection of misfolded proteins and the coordination of their disposal and is necessary to maintain the cellular homoeostasis. Multiple myeloma cells secrete large amounts of immunoglobulins, proteins that need to be correctly folded by the chaperone system. If this process fails, the misfolded proteins have to be eliminated by the two main g...

Antiretroviral therapy (ART) can control human immunodeficiency virus-1 (HIV-1) replication in infected individuals. Unfortunately, patients remain persistently infected owing to the establishment of latent infection requiring that ART be maintained indefinitely. One strategy being pursued involves the development of latency-reversing agents (LRAs) to eliminate the latent arm of the infection. ...

A major problem in the treatment of cancer and prolongation of patient survival is the dissemination of cells from a defined tumor site into a loco-regional disease and ultimately to full metastatic spread into distant organs. In the manuscript by Ierano et al. multiple chemically diverse histone deacetylase inhibitors (HDACIs) in tumor cell types of many diverse origins were shown to increase ...

Histone deacetylase inhibitors (HDACIs) cause oncogene‑transformed mammalian cell death. Our previous study indicated that HDACIs activate forkhead box O1 (FOXO1) and induce autophagy in liver and colon cancer cells. However, whether FOXO1 is involved in HDACI‑mediated oncogene‑transformed mammalian cell death remains unclear. In the present study, H‑ras transformed MCF10A cells were used to in...

Histone deacetylase inhibitors (HDACi) are currently used in the routine clinical treatment of cancer. Alongside the antitumor activity of HDACi, increased attention has been paid to their anti‑inflammatory effects. The present study aimed to analyze the inhibitory effects of the HDACi Trichostatin A (TSA), on the release of inflammatory mediators from macrophages differentiated from U‑937 cell...

PURPOSE Histone deacetylase inhibitors (HDACi) have recently emerged as efficacious therapies that target epigenetic mechanisms in hematologic malignancies. One such hematologic malignancy, B-cell acute lymphoblastic leukemia (B-ALL), may be highly dependent on epigenetic regulation for leukemia development and maintenance, and thus sensitive to small-molecule inhibitors that target epigenetic ...

Histone deacetylase inhibitors (HDACIs) have potent anti-cancer activity in a variety of cancer models. Understanding the molecular mechanisms involved in the therapeutic responsiveness of HDACI is needed before its clinical application. This study aimed to determine if a potent HDACI, LBH589 (Panobinostat), had differential therapeutic responsiveness towards LNCaP and PC-3 prostate cancer (PCa...
