Unstipulated and InexactIndeterminate Dendritic Cell Tumour by Anubha Bajaj in  Novel Approaches in Cancer Study






Opinion

Indeterminate dendritic cell tumour emerges as an extremely exceptional tumefaction composed of proliferation of dendritic cells or cells of histiocytic lineage. Additionally designated as indeterminate cell histiocytosis, indeterminate cell tumour or indeterminate dendritic cell tumour, true cutaneous dendritic cell tumour may depict solitary or multifocal lesions. Generally, tumefaction is confined to diverse cutaneous surfaces wherein deep seated visceral or regional lymph node involvement is exceptional. Tumour forming indeterminate cells simulate Langerhans cells vis-à-vis morphological and antigenic features. However, indeterminate cells appear devoid of Birbeck granules and lack immune reactivity to langerin (CD207). Median age of disease emergence is 45 years although no age of disease occurrence is exempt. An almost equivalent gender predilection is encountered. Indeterminate dendritic cell tumour predominantly(~88%) implicates diverse cutaneous surfaces. Infrequently, regional lymph nodes (9%) or spleen (2.3%) may be involved [1,2]. Of obscure a etiology, neoplasm expounds varied concurrence between indeterminate cells and Langerhans cells as ~indeterminate cells manifest as Langerhans cells devoid of Birbeck granules ~indeterminate cells represent as immature Langerhans cells. A subset of neoplasms express dendritic cell marker ZBTB46, thereby indicating the emergence of neoplasms directly from bone marrow progenitors, in contrast to embryonic precursors which undergo localized cutaneous regeneration [1,2].

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...
