The Miniscule Eaves-Micro-papillary Carcinoma Breast by Anubha Bajaj in 

Novel Approaches in Cancer Study


Abstract

Micro-papillary carcinoma breast emerges as an invasive, exfoliative neoplasm delineating characteristic pseudo-papillary, tubular or morula-like epithelial structures with an inverted or ‘inside out’ tumour pattern. Tumefaction exhibits upregulation of various nutrient transporters as glucose transporter 1 (GLUT1) through activation of transcription factor as hypoxia-inducible factor or upregulation of BC-1514 (C21 or f118), especially within micro-papillary areas. Tumour cells exhibit gains of chromosome 1q, 8q, 17q, 20q and loss of chromosome 1p, 8p, 13q, 16q and 20q. Cellular cytological smears delineate angulated clusters, abortive papillae and isolated malignant cells. Densely cellular tufts of cells configure pseudo-papillae, hollow tubules or morula with circumscribing clear spaces and minimal encompassing fibro-collagenous stroma. Characteristic reverse polarity or an ‘inside out’ pattern of tumour cells pervaded with abundant, eosinophilic cytoplasm, intracytoplasmic mucin and nuclei with a peripheral bulge, knobby or serrated appearance is observed. Neoplastic cells appear immune reactive to Epithelial Membrane Antigen (EMA), CD15s, E-cadherin, p120 catenin, oestrogen receptor(ER), Progesterone Receptor (PR), HER2 or GATA3.

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...
