January 20th, 2011. Targeted inhibition of multiple receptor tyrosine kinases in mesothelioma
HSP90 inhibition also suppressed phosphorylation of downstream signaling intermediates (AKT, mitogen-activated protein kinase, and S6); upregulated the p53, p21, and p27 cell cycle checkpoints; induced G(2) phase arrest; induced caspase 3/7 activity; and led to an increase in the sub-G(1) apoptotic population. These compelling proapoptotic and antiproliferative responses indicate that HSP90 inhibition warrants clinical evaluation as a novel therapeutic strategy in mesothelioma.
January 7th, 2011. The expression of CXCR4, CXCL12 and CXCR7 in malignant pleural mesothelioma
In conclusion, CXCR4 and CXCL12 are highly expressed in most mesothelioma cell lines and tumour tissues, suggesting that CXCR4 and CXCL12 may be used as biomarkers for patients with mesothelioma. The CXCL12–CXCR4 interaction may be a potential therapeutic target for mesothelioma.
January 6th, 2011. Summary of Presentations from the 46th Annual Meeting of the American Society of Clinical Oncology (2010) Focus on Tumor Biology and Biomarkers Related to Lung Cancer
Novel genetic mutations were identified in pleural mesothelioma using array-based technologies. Several studies on the development and testing of new molecular diagnostic tests to detect epidermal growth factor receptor tyrosine kinase mutations and EML4-ALK (Echinoderm Microtubule-associated Protein like 4 Anaplastic Lymphoma Receptor Tyrosine Kinase) fusion gene were presented as well.
January 5th, 2011. Antiangiogenic therapies for malignant pleural mesothelioma
Further understanding of the functional characteristics of tumor angiogenesis may be essential to improve targeting therapies in MPM. In this review, we introduce current status of clinical strategies and novel therapeutic approaches against angiogenesis in MPM.
December 20th, 2008. Phase II study of belinostat (PXD101), a histone deacetylase inhibitor, for second line therapy of advanced malignant pleural mesothelioma
Conclusions: Belinostat is not active as monotherapy against recurrent malignant pleural mesothelioma. Evaluation of combination strategies or alternate dosing schedules may be necessary for further development of this novel agent in mesothelioma.
December 17th, 2008. Systemic blockade of transforming growth factor-beta signaling augments the efficacy of immunogene therapy
E7 vaccination therapy. The addition of TGF-beta blocking agents in clinical trials of immunotherapies may increase efficacy.
December 17th, 2008. A binding domain on mesothelin for CA125/MUC16
In addition, we have shown that a single chain monoclonal antibody (SS1) recognizes this CA125-binding domain and blocks the mesothelin-CA125 interaction on cancer cells. The identified CA125-binding domain significantly inhibits cancer cell adhesion and merits evaluation as a new therapeutic agent for preventing or treating peritoneal malignant tumors.
November 21st, 2008. Laboratory investigation of hypercoagulability in cancer patients using rotation thrombelastography
In conclusions, our data demonstrates thromboelastographic signs of hypercoagulability in patients with solid tumors. ROTEM® is able to identify the contribution of fibrinogen and platelets to clot strength in this patient population.
October 22nd, 2008. Interaction of onconase with the human ribonuclease inhibitor protein
This inhibition occurs with Ki = 0. 15 μM in a solution of low salt concentration.
October 4th, 2008. Expression of the embryonic lethal abnormal vision-like protein HuR in human mesothelioma
Conclusions: The current results suggested that HuR plays a role in tumor progression in mesothelioma and that COX-2 may be a target of its activity in neoplastic cells. Together, these observations indicate that strategies aiming toward the modulation of HuR may have a potential clinical benefit in mesothelioma.
October 2nd, 2008. Inhibition of Hsp90 leads to cell cycle arrest and apoptosis in human malignant pleural mesothelioma
Conclusion: These results suggest that Hsp90 is strongly associated with the growth and survival of MM and that inhibition of Hsp90 may have therapeutic potential in the treatment of MM.
September 19th, 2008. Comparative immunohistochemistry of L19 and F16 in non-small cell lung cancer and mesothelioma: Two human antibodies investigated in clinical trials in patients with cancer
In our analysis, the anti-tenascin F16 antibody was found to generally exhibit a stronger staining of desmoplastic stroma surrounding tumor. This superior performance was found to be particularly striking in the case of low-grade non-small cell lung cancer.
September 5th, 2008. Systemic Treatments for Mesothelioma: Standard and Novel
These include drugs targeted against the epidermal growth factor, platelet-derived growth factor, vascular endothelial growth factor, src kinase, histone deacetylase, the proteasome, and mesothelin. Given the progress made in recent years, there is reason to believe that more effective treatments will continue to be developed.

September 4th, 2008. Protein kinase C beta in malignant pleural mesothelioma
Enzastaurin has preclinical activity against MPM, and exhibited synergism with cisplatin. PKC[beta] inhibition in MPM might be able to reduce the invasiveness of MPM by affecting cytoskeletal function.
September 2nd, 2008. Malignant Pleural Mesothelioma–Targeted CREBBP/EP300 Inhibitory Protein 1 Promoter System for Gene Therapy and Virotherapy
Moreover, these viruses showed antitumor effects in a mesothelioma xenograft mouse model. Here, we describe a novel strategy to target malignant mesothelioma using the CRI1(-138 4x) promoter system.
September 2nd, 2008. Stathmin 1: a novel therapeutic target for anticancer activity
Its expression is also upregulated in hepatocytes during regeneration and in lymphoid cells when they are signaled to proliferate. In this review, we summarize available data as rationale for the therapeutic manipulation of STMN1 in cancer patients.
August 30th, 2008. YAP1 is involved in mesothelioma development and negatively regulated by Merlin through phosphorylation
Future studies of transcriptional targets of YAP1 in MPMs may shed light on the molecular mechanisms of MPM development and lead to new therapeutic strategies. Abbreviations: BAC, bacterial artificial chromosome; CGH, comprehensive genomic hybridization; EGFP, enhanced green fluorescent protein; GST, glutathione S-transferase; MPM, malignant pleural mesothelioma; NF2, neurofibromatosis type 2; NHERF1, Na(+)/H(+) exchanger regulatory factor 1; PCR, polymerase chain reaction; RNAi, RNA interference; SDS, sodium dodecyl sulfate; sh, short hairpin.
August 30th, 2008. Novel Oncolytic Agent GLV-1h68 Is Effective Against Malignant Pleural Mesothelioma
GLV-1h68 was successfully used to treat MPM in vitro and in an orthotopic model (in vivo). These promising results warrant clinical investigation of GLV-1h68 as a novel agent in the treatment of MPM.
August 30th, 2008. Lysophosphatidic acid stimulates the proliferation and motility of malignant pleural mesothelioma cells through lysophosphatidic acid receptors, LPA1 and LPA2
These results indicate that LPA is a critical factor on proliferation though LPA1, and on motility though LPA2 in MPM cells. Therefore, LPA and LPA receptors, LPA2 as well as LPA1, represent potential therapeutic targets for patients with MPM.
