 Fas signaling pathway is known to be engaged in elimination of unwanted cells by apoptosis, however, new discoveries presented its alternate face, namely FasR and FasL play pro-cancerous functions facilitating cancer progression, invasion and metastasis. Here, we provide a brief summary of knowledge concerning Fas signaling pathway merits and disadvantages in cancer. Fas molecules were found to be engaged in many pathways induced by different therapeutic compounds, such as aspirin and antibiotics. This suggest that Fas signaling pathway may be employed as adjuvant factor for immunotherapy of variable design. Although, the literature presents some first optimistic results, we must intensify efforts to finally introduce Fasassociated procedures into standard therapeutic options. The Fas signaling is known to exert very variable effects in wide spectrum of cells. The FasR/ FasL (CD95/ CD95L) proteins can be associated with both positive (physiological) and negative (pathological) effects. Nowadays, there is a growing interest in the elucidation of the Fas signaling role in the pathogenesis and progression of various cancers. Additionally, it was proven that the expression of FasR/ FasL in colorectal cancer is associated with worse prognosis, metastasis and recurrence [1-6] the aspects of cancer biology which cancer stem cells are responsible for [7].

Recent Advances in the Therapeutic Approaches of Glioblastoma Multiforme_Crimson Publishers

  Recent Advances in the Therapeutic Approaches of Glioblastoma Multiforme by Siddharth Shah in  in Novel Approaches in Cancer Study Abstract Glioblastoma Multiforme (GBM, WHO grade IV) is one of the most aggressive, invasive, and lethal intracranial neoplasms, with a low post-diagnosis survival rate. Standard-of-care treatment regimens involving maximal surgical resection, radiotherapy, and genetic anti-tumor compounds like Temozolomide have only been marginally effective in improving overall survival and quality of life. Cell fusion, autophagy, and other complex biological processes affecting GBM pathophysiology are being studied to improve GBM treatment. This paper therefore focuses on oncolytic virus therapy combined with surgical resection, photodynamic therapy, and novel gene therapy, demonstrating how GBM treatment for patients could result in immediate and authentic tumor cytotoxicity and removal, rather than treatment of recurrent GBM. Standard therapy for GBM,...

Release of Inorganic Phosphate into the Tumor Environment: Possible Roles of Ecto- Nucleotidases and Ecto-Phosphatases

Abstract Inorganic phosphate (Pi) is essential for several biochemical reaction. Serum Pi is maintained at relatively narrow range concentrations, between 0.7 and 1.55mM. Tumor microenvironment presents a high Pi concentration (1.8±0.2mM Pi) and this could be associated wi the rapid growth in the “Growth Rate Hypothesis”. Several studies have identified high expression of Pi transporters in various tumor tissues. Similarly, ecto-enzymes (like ecto-nucleotidases or ecto- phosphates) act by dephosphorylating phosphosubstrates in the extracellular environment, and its high expression has been observed in various types of cancer. Little is known about the function of these ecto-enzymes on Pi releasing and accumulation in the tumor environment. Therefore, the purpose of this study is to correlate a possible contribution of the Pi release in the tumor microenvironment by ecto-nucleotidases and ecto-phosphatases, concomitant to the regulation of Pi extracellular pool by specific Pi...
