Background: Gene therapeutic-delivered overexpression of Pglycoprotein (P-gp), the product of MDR1 (multidrug resistance 1) gene, might protect normal tissue during chemoand radiotherapy of P-gp-expressing tumors. However, little is known about the influence of MDR1-overexpression on the expression of other genes. Methods: Differentially gene expression in untransduced and oncoretrovirally tran...
Neisseria gonorrhoeae (Ngo) has developed multiple immune evasion mechanisms involving the innate and adaptive immune responses. Recent findings have reported that Ngo reduces the IL-1β secretion of infected human monocyte-derived macrophages (MDM). Here, we investigate the role of adenosine triphosphate (ATP) in production and release of IL-1β in Ngo-infected MDM. We found that the exposure of...
OBJECTIVES Epigenetics can influence disease susceptibility and severity. While DNA methylation of individual genes has been explored in autoimmunity, no unbiased systematic analyses have been reported. Therefore, a genome-wide evaluation of DNA methylation loci in fibroblast-like synoviocytes (FLS) isolated from the site of disease in rheumatoid arthritis (RA) was performed. METHODS Genomic ...
The mammalian target of rapamycin complex 1 (mTORC1) is hyperactive in many human cancers and in tuberous sclerosis complex (TSC). Autophagy, a key mTORC1-targeted process, is a critical determinant of metabolic homeostasis. Metabolomic profiling was performed to elucidate the cellular consequences of autophagy dysregulation under conditions of hyperactive mTORC1. It was discovered that TSC2-nu...
Non-melanoma skin cancer is the most common in fair-skinned adults and comprises basal cell carcinoma squamous (SCC). Its incidence reaches 1 of 100 person-year Australia (Lomas et al., 2012Lomas A. Leonardi-Bee J. Bath-Hextall F. A systematic review worldwide nonmelanoma cancer.Br J Dermatol. 2012; 166: 1069-1080Crossref PubMed Scopus (1126) Google Scholar) still on rise (Madan 2010Madan V. Le...
Nucleotide-binding and oligomerization domain-like receptors (NLRs) constitute a family of germline-encoded pattern-recognition receptors, which allow the host to respond rapidly to a wide variety of pathogenic microorganisms. Here, we discuss recent advances in the study of a subset of NLRs, which control the activation of caspase-1 through the assembly of large protein complexes, inflammasome...
Because of their outstanding physical properties, carbon nanotubes (CNTs) are promising new materials in the field of nanotechnology. It is therefore imperative to assess their adverse effects on human health. Monocytes/macrophages that recognize and eliminate the inert particles constitute the main target of CNTs. In this article, we report our finding that double-walled CNTs (DWCNTs) synergiz...
Expansion of a polyglutamine repeat in huntingtin causes Huntington's disease (HD). Although full-length huntingtin is predominantly distributed in the cytoplasm, N-terminal fragments of huntingtin with expanded polyglutamine tracts are able to accumulate in the nucleus and kill neurons through apoptotic pathways. Transgenic mice expressing N-terminal mutant huntingtin show intranuclear hunting...
Toll-like receptors (TLRs)-2 and -4 are important proteins in innate immunity, recognizing microbial products and eliciting host defense responses. Both use the adapter proteins MyD88 and MyD88 adapter-like (Mal) to activate signaling pathways. Here we report that Mal but not MyD88 interacts with caspase-1, the enzyme that processes the precursors of the proinflammatory cytokines IL-1beta and I...
Caspase-associated recruitment domains (CARD) are protein-protein interaction modules found extensively in proteins that play important roles in apoptosis, NFkappaB activation, and cytokine regulation. In this study we identified a novel human protein, CARD-8, which contains a C-terminal CARD domain with high similarity to the CARD domain of caspase-1/ICE. We demonstrate that CARD-8 interacts p...
