Dysfunctional pulmonary homeostasis and repair, including diseases such as pulmonary fibrosis (PF), chronic obstructive pulmonary disease (COPD), and tumorigenesis have been increasing over the past decade, a fact that heavily implicates environmental influences. Several investigations have suggested that in response to increased transforming growth factor--beta (TGFβ) signaling, the alveolar t...

Signal transduction controls cellular and tissue responses to radiation. Transforming growth factor beta (TGFβ) is animportant regulator of cell growth and differentiation and tissue homeostasis, and is often dis-regulated in tumorformation. Mathematical models of signal transduction pathways can be used to elucidate how signal transductionvaries with radiation quality, and dose and...

The major high-affinity thrombin receptor, proteinase activated receptor-1 (PAR-1) is expressed at low levels by the normal epithelium but is upregulated in many types of cancer, including lung cancer. The thrombin-PAR-1 signalling axis contributes to the activation of latent TGFβ in response to tissue injury via an αvβ6 integrin-mediated mechanism. TGFβ is a pleiotropic cytokine that acts as a...

stroke is the leading cause of death and disability in the world after the cancer and cardiovascular diseases. genetic factors have main significance to got stroke. renin-angiotensin system contains candidate genes and polymorphisms for causing stroke. there are reported associations between stroke and angiotensin ii type-1 receptor g. 1166a > c polymorphism (rs5186). therefore in this study th...

BACKGROUND Myofibroblasts are the critical effector cells in the pathogenesis of pulmonary fibrosis which carries a high degree of morbidity and mortality. We have previously identified Type II TGFβ receptor interacting protein 1 (TRIP-1), through proteomic analysis, as a key regulator of collagen contraction in primary human lung fibroblasts--a functional characteristic of myofibroblasts, and ...
