Zinc-finger protein 326 (ZNF326) activity has been reported in different tumors, but its expression and possible mechanism of action in colorectal cancer are not known. In this study, we applied immunohistochemistry to detect the expression of ZNF326 in colorectal tissues. Next, we used a ZNF326 expression plasmid and small interfering (si) RNA-ZNF326 (siZNF326) to transfect colorectal cancer cell lines in order to determine the effect of ZNF326 on cell migration and as well as its potential role in promoting epithelial-mesenchymal transition (EMT)...

TMEM180, a novel colon cancer-specific protein with a 12-transmembrane topology, is upregulated at low oxygen. Previously, we established a humanized monoclonal antibody against TMEM180 aimed at clinical trials. Prior to such trials, it is necessary to clarify the function of TMEM180 in cancer. To compare SW480 human colon cancer cells and their TMEM180-knockdown derivatives, we analyzed proliferation and oxygen consumption, and also performed phosphorylation proteomics, metabolomics, and next-generation sequencing (NGS)...

AIM: Parastomal hernia (PSH) is a common problem following colostomy. Using prophylactic mesh during end colostomy creation may reduce PSH incidence, but concerns exist regarding the optimal type of mesh, potential long-term complications, and cost-effectiveness of its use. We evaluated the cost-effectiveness of mesh prophylaxis to prevent PSH in patients undergoing end colostomy for rectal cancer. METHODS: We developed a decision-analytical model, stratified by rectal cancer stages I-IV, to estimate the lifetime costs, quality-adjusted life-years (QALYs) and net monetary benefits (NMBs) of synthetic, biologic and no mesh from a UK NHS perspective...

Colorectal cancer (CRC) constitutes the third most commonly diagnosed cancer in males and the second in females. Precise histopathological classification of CRC tissue pathology is the cornerstone not only for diagnosis but also for patients' management decision making. An automated system able to accurately classify different CRC tissue regions may increase diagnostic precision and alleviate clinical workload. However, tissue classification is a challenging task due to the variability in morphological and textural characteristics present in histopathology images...

Alternative splicing (AS) is an important event that contributes to posttranscriptional gene regulation. This process leads to several mature transcript variants with diverse physiological functions. Indeed, disruption of various aspects of this multistep process, such as cis- or trans- factor alteration, promotes the progression of colorectal cancer. Therefore, targeting some specific processes of AS may be an effective therapeutic strategy for treating cancer. Here, we provide an overview of the AS events related to colorectal cancer based on research done in the past 5 years...

Human γδ T cells contribute to tissue homeostasis and participate in epithelial stress surveillance through mechanisms that are not well understood. Here, we identified ephrin type-A receptor 2 (EphA2) as a stress antigen recognized by a human Vγ9Vδ1 TCR. EphA2 is recognized coordinately by ephrin A to enable γδ TCR activation. We identified a putative TCR binding site on the ligand-binding domain of EphA2 that was distinct from the ephrin A binding site. Expression of EphA2 was up-regulated upon AMP-activated protein kinase (AMPK)-dependent metabolic reprogramming of cancer cells, and coexpression of EphA2 and active AMPK in tumors was associated with higher CD3 T cell infiltration in human colorectal cancer tissue...

BACKGROUND: Statins preferentially promote tumor-specific apoptosis by depleting isoprenoid such as farnesyl pyrophosphate and geranylgeranyl pyrophosphate. However, statins have not yet been approved for clinical cancer treatment due, in part, to poor understanding of molecular determinants on statin sensitivity. Here, we investigated the potential of statins to elicit enhanced immunogenicity of KRAS -mutant ( KRAS mut ) tumors. METHODS: The immunogenicity of treated cancer cells was determined by western blot, flow cytometry and confocal microscopy...

The gastrointestinal tract is a complex interface between the external environment and the immune system. Its ability to control uptake across the mucosa and to protect the body from damage of harmful substances from the lumen is defined as the intestinal barrier function (IBF). The IBF involves four elements: the intestinal microbiota, the mucus layer, the epithelium and the immune system. Its dysfunction is linked with human diseases including inflammatory, metabolic, infectious, autoimmune and neurologic disorders...

Abscopal effect is an attractive cancer therapeutic effect referring to tumor regression at a location distant from the primary treatment site. Immunogenic cell death (ICD) offers a mechanistic link between the primary and remote therapeutic effects by activating favorable anti-tumor immune responses. In this study, we induced ICD in colorectal cancer (CRC) cell lines in vitro and in vivo by targeting the 18 kDa translocator protein (TSPO), a mitochondrial receptor overexpressed in CRC. Photodynamic therapy (PDT) using a TSPO-targeted photosensitizer, IR700DX-6T, caused effective apoptotic cell death in fourteen CRC cell lines...

Colorectal cancer (CRC) is the second leading cause of cancer-related deaths worldwide. The primary treatment for CRC is surgical resection, along with chemotherapy in more advanced or inoperable cases. There is a growing interest to complement both curative and palliative treatment with immunotherapies such as the programmed cell death-1 (PD-1) and PD-ligand 1 (PDL1) checkpoint inhibitors and transforming growth factor (TGF) β inhibitors. However, the clinical outcomes of current immunotherapeutic strategies are limited by tumor heterogeneity and drug resistance...
