NovoCure’s cancer therapy effective in late-stage study

(Reuters) – NovoCure (NSDQ:NVCR) said its lead cancer therapy improved survival rate in brain cancer patients in combination with Avastin in a late-stage study, sending its shares up 23% in extended trading. NovoCure’s therapy, Optune, which was evaluated in combination with Roche Holding AG’s cancer drug, reduced the risk of death by 39% in patients, compared with patients treated with Avastin alone, Novocure said in a statement on Friday. Optune is an FDA-approved device for use in patients with glioblastoma multiforme (GBM), the most common and aggressive form of brain tumor in which 90% of adult patients die within 24 months after the diagnosis. The portable, non-invasive device uses low-intensity electric fields to slow and even reverse tumor growth and destroy the cancer cells. Optune in combination with Merck &Co Inc’s chemotherapy drug, temozolomide, was approved by the FDA in October to treat adult patients. Novocure, which went public in October, said it plans to present the data from the study at the 20th Annual Society for Neuro-Oncology Meeting in San Antonio, Texas. The company’s shares closed down 1.6 percent at $22.04 on the Nasdaq on Friday. The post NovoCure’s cancer therapy effective in late-stage study appeared first on MassDevice.

In this study, to improve our understanding of the role of ATP1A1 in the malignant phenotype and pathogenesis of GSCs, we evaluated ATP1A1 expression in GBMs of different grades and in two primary GSC lines established from human GBM tissues. We evaluated the role of ATP1A1 in GSC growth, its interactions with Src, and the activation of the ERK1/2 and AKT pathways. Our results revealed that ATP1A1 acts as an oncogene in our GSC models and targeting ATP1A1/Src may suppress GSC proliferation and growth. Materials and Methods Cell Isolation and Culture Human brain GBM tissues were from pathologically confirmed surgical spe...

Conclusions This review describes how leukocyte-heparanase can be a double-edged sword in tumor progression; it can enhance tumor immune surveillance and tumor cell clearance, but also promote tumor survival and growth. We also discuss the potential of using heparanase in leukocyte therapies against tumors, and the effects of heparanase inhibitors on tumor progression and immunity. We are just beginning to understand the influence of heparanase on a pro/anti-tumor immune response, and there are still many questions to answer. How do the pro/anti-tumorigenic effects of heparanase differ across different cancer types? Does...

Conclusion Several TISC-based immunotherapeutic approaches are under development in various stages of preclinical studies. As outlined in this review article, a careful and more exhaustive genetic and metabolic understanding of TISC-associated phenotypes is critical to develop novel TISC based immunotherapies. Various components within the tumor microenvironment such as tumor cells, infiltrating immune cells, and supporting stromal cells impact the TISC metabolism. This unique metabolic profile leads to upregulation of certain enzymes and proteins such as ALDH1, CEP55, IDO COA1 etc., which can be utilized for development ...

Abstract Alkylating agents have been used since the 60ties in brain cancer chemotherapy. Their target is the DNA and, although the DNA of normal and cancer cells is damaged unselectively, they exert tumor-specific killing effects because of downregulation of some DNA repair activities in cancer cells. Agents exhibiting methylating properties (temozolomide, procarbazine, dacarbazine, streptozotocine) induce at least 12 different DNA lesions. These are repaired by damage reversal mechanisms involving the alkyltransferase MGMT and the alkB homologous protein ALKBH2, and through base excision repair (BER). There is a ...

Discussion Suppressor of cytokine signaling 1 is an essential molecule for maintaining immune homeostasis and subverting inflammation. Disorders arising from excess inflammation or SOCS1 deficiency can be potentially treated with SOCS1 mimetics (Ahmed et al., 2015). While SOCS1 has promising potential in many disorders, it should be noted that new targets and actions of SOCS1 are still being discovered and not all the effects of this protein are beneficial in autoimmune diseases and cancer. For instance, SOCS1 degrades IRS1 and IRS2, required for insulin signaling, via the SOCS Box domain, thus, limiting its potential in ...

We examined the following three conditions: DMEM high glucose which contained 4.5 mg/ml glucose, independent of serum, DMEM low glucose which contained 1.0 mg/ml glucose, independent of serum. And, DMEM no glucose which contained 0.0 mg/ml glucose, independent of serum. DMEM is referred to as glucose “free,” however some glucose was actually present due to the FBS. The glucose concentration in the FBS used was 1.04 mg/ml. We calculate 0.0937 mg/ml glucose was present in the media under all conditions due to the addition of serum. Quantification of ROS Levels ROS are widely evaluated in tissue culture using di...

Authors: Ni W, Luo L, Zuo P, Li R, Xu X, Wen F, Hu D Abstract Glioma is a commonly diagnosed brain tumor that show high mortality rate. Despite the great advancement of cancer therapy in recent years, chemotherapy is still an important approach for treatment of glioma. However, long-term chemotherapy usually causes serious side-effects or complications. We are supposed to take strategies to enhance the efficacy of current chemotherapy. In the present study, we observed obvious upregulation of miR-374a in glioma cells. More importantly, we found that knockdown of miR-374a was able to enhance the etoposide-induced cy...
