The hepatitis C virus (HCV) leads to chronic disease in 80% of those infected and is associated with a chronic inflammatory response that is mediated by both cytokine producing (CD4+) and cytotoxic T cells (CD8+). FoxP3-expressing, CD4+, CD25+T cells (T-regs) are a subset of T lymphocytes that inhibit immune responsiveness and thereby control immunological reactions. Whether FoxP3+ T regulatory cell-mediated suppression is a factor in HCV persistence and/or the course of chronic liver injury has not been defined. In order to assess the association between these T regulatory cells and the severity of chronic hepatitis C, we evaluated liver biopsies …

Metabolic engineering of cellular systems to maximize reaction fluxes or metabolite concentrations still presents a significant challenge by encountering unpredictable instabilities that can be caused by simultaneous or consecutive enhancements of many reaction steps. It can therefore be important to select carefully small subsets of key enzymes for their subsequent stable modification compatible with cell physiology. To address this important problem, we introduce a general mixed integer non-linear problem (MINLP) formulation to compute automatically which enzyme levels should be modulated and which enzyme regulatory structures should be altered to achieve the given optimization goal using non-linear kinetic models of relevant …

Proteoglycans located in basement membranes, the nanostructures underling epithelial and endothelial layers, are unique in several respects. They are usually large, elongated molecules with a collage of domains that share structural and functional homology with numerous extracellular matrix proteins, growth factors and surface receptors. They mainly carry heparan sulfate side chains and these contribute not only to storing and preserving the biological activity of various heparan sulfate-binding cytokines and growth factors, but also in presenting them in a more "active configuration" to their cognate receptors. Abnormal expression or deregulated function of these proteoglycans affect cancer and angiogenesis, and are critical …

While semaphorins and their receptors appear to play a role in tumor carcinogenesis, little is known about the role of semaphorin 3F (S3F) in epithelial ovarian cancer (EOC) development. Therefore, we sought to determine the clinical relationship between S3F and its receptors, neuropilin-2 (NP-2) and neuropilin-1 (NP-1) with EOC progression. We analyzed the immunohistological expression of S3F, NP-2, and NP-1 in clinical specimens of normal ovaries (N), benign cystadenomas (Cy), well-differentiated adenocarcinomas (WD), poorly-differentiated adenocarcinomas (PD), inclusion cysts (IC), paraovarian cysts (PC), and fallopian tubes (FT). Tissue sections were evaluated for staining intensity and percentage of immunoreactive epithelia. We found …

Our study suggest that E-cadherin downregulation may lead to EZH20-mediated invasion and metastasis. While strong diffuse EZH2 expression is seen in PDA, overexpression may be present in IPMN.

In contrast to previous work, our preliminary results indicate B72.3 expression cannot be reliably used to identify GIC. A lack of CEA expression, however, may be used to identify both gastric and duodenal contamination. This represents an important diagnostic aid in the evaluation of suspected low-grade mucinous lesions.
