Although cell-in-cell structures (CICs) could be detected in a wide range of human tumors, homotypic CICs formed between tumor cells occur at low rate for most of them. We recently reported that tumor cells lacking expression of E- and P-cadherin were incapable of forming homotypic CICs by entosis, and re-expression of E- or P-cadherin was sufficient to(More)
We performed an analysis of the efficacy of capecitabine monotherapy as maintenance treatment for metastatic breast cancer (MBC) after response to capecitabine-based chemotherapy [capecitabine plus docetaxel (XT) or vinorelbine (XN)] as a first-line or a second-line treatment. Sixty-four Chinese patients with histologically confirmed MBC received(More)
OBJECTIVE To observe the expression of nuclear protein 1 (Nupr1), a stress-related nuclear protein, in a panel of human hepatocellular carcinoma cell lines, and its effects on the proliferation and migration of hepatocellular carcinoma cells by RNA interference-mediated knockdown. METHODS Real-time quantitative PCR was employed to detect Nupr1 mRNA levels(More)
Cell engulfment typically targets dead or dying cells for clearance from metazoan tissues. However, recent evidence demonstrates that live cells can also be targeted and that engulfment can cause cell death. Entosis is one mechanism proposed to mediate the engulfment and killing of live tumor cells by their neighbors, an activity often referred to as cell(More)
We study a two-stage purchase contract with a demand forecast update. The purchase contract provides the buyer an opportunity to adjust an initial commitment based on an updated demand forecast obtained at a later stage. An adjustment, if any, incurs a fixed as well as a variable cost. Using a dynamic programming formulation, we obtain optimal solutions for(More)
Although Cell-in-cell structures (CICs) had been documented in human tumors for decades, it is unclear what types of CICs were formed largely due to low resolution of traditional way such as H&E staining. In this work, we employed immunofluorescent method to stain a panel of human tumor samples simultaneously with antibodies against E-cadherin for(More)
The engulfment of live cells may represent a mechanism of cell death. We reported that E-cadherin (epithelial cadherin) expression in human cancer cells favors the formation of cell-in-cell structures through the mechanism known as entosis, and that entosis contributes to a form of cellular competition in heterogeneous cancer cell populations.
Cell-in-cell structures (CICs), characterized by the presence of one or more viable cells inside another one, were recently found important player in development, immune homeostasis and tumorigenesis etc. Incompatible with ever-increasing interests on this unique phenomenon, reliable methods available for high throughput quantification and systemic(More)
In a screen of signal peptide-containing proteins from a mouse hypothetical protein library, we identified the mouse UDP-GlcNAc:lysosomal enzyme N-acetylglucosamine-1-phosphotransferase-gamma chain (GlcNAc-1-phosphotransferase-gamma) (GenBank accession no. , HYP36 in this study). The mouse GlcNAc-1-phosphotransferase-gamma was localized in the Golgi complex(More)
Statin intake has been reported to reduce the risk of several malignancies beyond its cholesterol-lowering effects. However, little is known regarding the survival benefit of statins for patients with colorectal cancer (CRC).We conducted a systematic literature search of multiple databases for studies published before November 2014, which investigated(More)
