Within the Special Research Group of Department of Health and Welfare, seven research subgroups which are testing different types of interferon supplied from each seven companies are organized at the time of October 1982. Out of these subgroups, two groups, Toray company group (IFN-beta) and Sumitomo company group (HLBI-alpha), have made clinical trials on 123 cases and 120 cases respectively. Other groups are still under preparation. 6 cases with complete response and 23 cases with partial response by IFN-beta, and 0 cases with complete response and 13 cases with partial response by HLBI-alpha are observed. Over all responded disease are such as glioblastoma, medulloblastoma, melanoma and cutaneous T-cell lymphoma with local injection, and hypernephroma, bladder carcinoma, medulloblastoma, multiple myeloma, and adult T-cell leucaemia with systemic administration.

The role of response gene to complement (RGC)-32 as a cell cycle regulator has been attributed to its ability to activate cdc2 kinases and to induce S-phase entry and mitosis. However, recent studies revealed novel functions for RGC-32 in diverse processes such as cellular differentiation, inflammation, and fibrosis. Besides responding to C5b-9 stimulation, RGC-32 expression is also induced by growth factors, hormones, and cytokines. Transforming growth factor beta activates RGC-32 through Smad and RhoA signaling, thus initiating smooth muscle cell differentiation. Accumulating evidence has drawn attention to the deregulated expression of RGC-32 in human malignancies, hyper-immunoglobulin E syndrome, and fibrosis. RCG-32 expression is up-regulated in cutaneous T cell lymphoma and colon, ovarian, and breast cancer, but down-regulated in invasive prostate cancer, multiple myeloma, and drug-resistant glioblastoma. A better understanding of the mechanism by which RGC-32 contributes to the pathogenesis of these diseases will provide new insights into its therapeutic potential. In this review we provide an overview of this field and discuss the most recent research on RGC-32.

Autophagy is a cellular catabolic pathway by which long-lived proteins and damaged organelles are targeted for degradation. Activation of autophagy enhances cellular tolerance to various stresses. Recent studies indicate that a class of anticancer agents, histone deacetylase (HDAC) inhibitors, can induce autophagy. One of the HDAC inhibitors, suberoylanilide hydroxamic acid (SAHA), is currently being used for treating cutaneous T-cell lymphoma and under clinical trials for multiple other cancer types, including glioblastoma. Here, we show that SAHA increases the expression of the autophagic factor LC3, and inhibits the nutrient-sensing kinase mammalian target of rapamycin (mTOR). The inactivation of mTOR results in the dephosphorylation, and thus activation, of the autophagic protein kinase ULK1, which is essential for autophagy activation during SAHA treatment. Furthermore, we show that the inhibition of autophagy by RNAi in glioblastoma cells results in an increase in SAHA-induced apoptosis. Importantly, when apoptosis is pharmacologically blocked, SAHA-induced nonapoptotic cell death can also be potentiated by autophagy inhibition. Overall, our findings indicate that SAHA activates autophagy via inhibiting mTOR and up-regulating LC3 expression; autophagy functions as a prosurvival mechanism to mitigate SAHA-induced apoptotic and nonapoptotic cell death, suggesting that targeting autophagy might improve the therapeutic effects of SAHA.

HDAC inhibitors emerged as promising drug candidates in combating wide variety of cancers. At present, two of the compounds SAHA and Romidepsin were approved by FDA for cutaneous T-cell lymphoma and many are in various clinical phases. A new quinolone cap structure was explored with hydroxamic acid as zinc-binding group (ZBG). The pan HDAC inhibitory and antiproliferative activities against three human cancer cell lines HCT-116 (colon), NCI-H460 (lung) and U251 (glioblastoma) of the compounds (4a-4w) were evaluated. Introduction of heterocyclic amines in CAP region increased the enzyme inhibitory and antiproliferative activities and few of the compounds tested are metabolically stable in both MLM and HLM.

Non-Hodgkin lymphoma (NHL) and leukemia are among the most common cancers worldwide. While the treatment of NHL/leukemia of B-cell origin has much progressed with the introduction of targeted therapies, few treatment standards have been established for T-NHL/leukemia. As presentation in both B- and T-NHL/leukemia patients is often aggressive and as prognosis for relapsed disease is especially dismal, this cancer entity poses major challenges and requires innovative therapeutic approaches. In clinical trials, oncolytic viruses (OVs) have been used against refractory multiple myeloma (MM). In preclinical settings, a number of OVs have demonstrated a remarkable ability to suppress various types of hematological cancers. Most studies dealing with this approach have used MM or B- or myeloid-cell-derived malignancies as models. Only a few describe susceptibility of T-cell lymphoma/leukemia to OV infection and killing. The rat H-1 parvovirus (H-1PV) is an OV with considerable promise as a novel therapeutic agent against both solid tumors (pancreatic cancer and glioblastoma) and hematological malignancies. The present perspective article builds on previous reports of H-1PV-driven regression of Burkitt's lymphoma xenografts and on unpublished observations demonstrating effective killing by H-1PV of cells from CHOP-resistant diffuse large B-cell lymphoma, cutaneous T-cell lymphoma, and T-cell acute lymphoblastic leukemia. On the basis of these studies, H-1PV is proposed for use as an adjuvant to (chemo)therapeutic regimens. Furthermore, in the light of a recently completed first parvovirus clinical trial in glioblastoma patients, the advantages of H-1PV for systemic application are discussed.
