In a series of 111 patients with squamous cell carcinoma (SCC), we used immunohistochemistry to examine the expression levels of four epidermal growth factor receptor (EGFR) family members (EGFR, HER-2/neu, HER-3, and HER-4). Expression of the EGFR members was not significantly associated with tumor size. However, their expressions (except for HER-4) were(More)
BACKGROUND & AIMS Interleukin-1 beta (IL-1beta) polymorphisms are associated with increased risk of gastric cancer in whites. This study aimed to examine effects of these polymorphisms on gastric acid secretion, atrophic gastritis, and risk of peptic ulcer in Japan. METHODS We determined IL-1B-511/-31 and IL-1RN genotypes and measured gastric juice pH,(More)
A conditioning lesion to peripheral axons of primary sensory neurons accelerates regeneration of their central axons in vivo or neurite outgrowth if the neurons are grown in vitro. Previous evidence has implicated neuropoietic cytokines and also cyclic AMP in regenerative conditioning. In experiments reported here, delivery through a lentivirus vector of(More)
BACKGROUND AND AIM In Western countries, polymorphism of pro-inflammatory cytokine genes is associated with the development of gastric cancer and duodenal ulcer. The aim of this study was to clarify the association of polymorphisms of interleukin (IL)-1beta and tumor necrosis factor (TNF)-alpha with susceptibility to peptic ulcer diseases and gastric cancer(More)
Exposure to methyltertiary-butyl ether (MTBE), a commonly used octane booster in gasoline, has previously been shown to alter various muscle, kidney, and liver metabolic activities. In the present study, the metabolism of MTBE by liver microsomes from acetoneor phenobarbital-treated Sprague-Dawley rats was studied at concentrations of up to 5 mM MTBE.(More)
Skeletal muscle stem cell-derived myoblasts are mainly responsible for postnatal muscle growth and injury-induced muscle regeneration. However, the cellular signaling pathways controlling the proliferation and differentiation of myoblasts are not fully understood. We demonstrate that Janus kinase 1 (JAK1) is required for myoblast proliferation and that it(More)
Skeletal muscle satellite cell-derived myoblasts are mainly responsible for postnatal muscle growth and injury-induced regeneration. However, the cellular signaling pathways that control proliferation and differentiation of myoblasts remain poorly defined. Recently, we found that JAK1/STAT1/STAT3 not only participate in myoblast proliferation but also(More)
Adoptive transfer of ex vivo expanded CD4(+)CD25(+)FOXP3(+) regulatory T cells is a successful therapy for autoimmune diseases and transplant rejection in experimental models. In man, equivalent manipulations in bone marrow transplant recipients appear safe, but questions regarding the stability of the transferred regulatory T cells during inflammation(More)
Asthma is a chronic condition with unknown pathogenesis, and recent evidence suggests that enhanced airway epithelial chloride (Cl-) secretion plays a role in the disease. However, the molecular mechanism underlying Cl- secretion and its relevance in asthma pathophysiology remain unknown. To determine the role of the solute carrier family 26, member 9(More)
