The fallacy of tumor immunology: Evolutionary pressures, viruses as nature's genetic engineering tools and T cell surveillance emergence for purging nascent selfish cells [PDF]

open access: yesarXiv, 2016
The US and Hungarian statistical records of the years 1900 and 1896, respectively, before the dramatic medical advances, show 32% and 27% deaths attributable to infections, whereas only 5% and 2% due to cancer. These data can be interpreted to mean that (i) the immune system evolved for purging nascent selfish cells, which establish natural chimerism ...

Elastic free energy drives the shape of prevascular solid tumors [PDF]

open access: yes, 2014
It is well established that the mechanical environment influences cell functions in health and disease. Here, we address how the mechanical environment influences tumor growth, in particular, the shape of solid tumors. In an in vitro tumor model, which isolates mechanical interactions between tumor cells and a hydrogel, we find that tumors grow as ...

Concise Review: Humanized Models of Tumor Immunology in the 21st Century: Convergence of Cancer Research and Tissue Engineering

open access: yesStem Cells, 2015
Despite positive testing in animal studies, more than 80% of novel drug candidates fail to proof their efficacy when tested in humans. This is primarily due to the use of preclinical models that are not able to recapitulate the physiological or ...

Tonic signaling of the B‐cell antigen‐specific receptor is a common functional hallmark in chronic lymphocytic leukemia cell phosphoproteomes at early disease stages

open access: yesMolecular Oncology, EarlyView.
B‐cell chronic lymphocytic leukemia (B‐CLL) and monoclonal B‐cell lymphocytosis (MBL) show altered proteomes and phosphoproteomes, analyzed using mass spectrometry, protein microarrays, and western blotting. Identifying 2970 proteins and 316 phosphoproteins, including 55 novel phosphopeptides, we reveal BCR and NF‐kβ/STAT3 signaling in disease ...

NLRC5, a promising new entry in tumor immunology

open access: yesJournal of Immunotherapy for Cancer, 2016
The recent use of T cell-based cancer immunotherapies, such as adoptive T-cell transfer and checkpoint blockade, yields increasing clinical benefit to patients with different cancer types. However, decrease of MHC class I expression is a common mechanism

Aberrant expression of nuclear prothymosin α contributes to epithelial‐mesenchymal transition in lung cancer

open access: yesMolecular Oncology, EarlyView.
Nuclear prothymosin α inhibits epithelial‐mesenchymal transition (EMT) in lung cancer by increasing Smad7 acetylation and competing with Smad2 for binding to SNAI1, TWIST1, and ZEB1 promoters. In early‐stage cancer, ProT suppresses TGF‐β‐induced EMT, while its loss in the nucleus in late‐stage cancer leads to enhanced EMT and poor prognosis.

Research Progress of Warburg Effect in Hepatocellular Carcinoma

open access: yesFrontiers in Bioscience-Landmark
The Warburg effect, also called aerobic glycolysis, refers to tumor cells that metabolize glucose through glycolysis even in the presence of oxygen. This rapid breakdown of glucose fuels the fast development, growth, and migration of tumor cells. Lactate,

Modelling Immunological Memory [PDF]

open access: yesIn Silico Immunology, 83-108, 2006, 2010
Accurate immunological models offer the possibility of performing highthroughput experiments in silico that can predict, or at least suggest, in vivo phenomena. In this chapter, we compare various models of immunological memory. We first validate an experimental immunological simulator, developed by the authors, by simulating several theories of ...

The architecture of co-culture spheroids regulates tumor invasion within a 3D extracellular matrix [PDF]

open access: yesarXiv, 2020
Tumor invasion, the process by which tumor cells break away from their primary tumor and gain access to vascular systems, is an important step in cancer metastasis. Most current 3D tumor invasion assays consisted of single tumor cells embedded within an extracellular matrix (ECM). These assays taught us much of what we know today on how key biophysical
