High glucose leads to physio/pathological alterations in diabetes patients. We investigated collagen production in human gingival cells that were cultured in high concentrations of glucose. Collagen synthesis and secretion were increased when the cells were exposed to high concentrations of glucose. We examined endoplasmic reticulum (ER) stress response because glucose metabolism is related to ER functional status. An ER stress response including the expression of glucose regulated protein 78... -

and immunoblot analysis. The mRNA levels of desmin, transferrin, Ձ-actin-2, HSP27, KCTD11, and MHC-Ih were up-regulated by over 1.5-fold, and showed a pattern similar to their proteomic profiles. Desmin and Ձ-actin-2 protein showed positive correlations between proteomic analysis and immunoblot analysis. These results suggest that desmin and Ձ-actin-2 may play important roles in endometritis-related function, and could be useful markers for the diagnosis of bovine endometritis. -

Cardiac fibroblasts constitute one of the largest cell populations in the heart, and contribute to structural, biochemical, mechanical and electrical properties of the myocardium. Nonetheless, their cardiac functions, especially electrophysiological properties, have often been disregarded in studies. Ca2+-activated K+ (KCa) channels can control Ca2+ influx as well as a number of Ca2+-dependent physiological processes. We, therefore, attempted to identify and characterize KCa channels in rat... -

In this study, the authors investigated whether death of vascular smooth muscle cell (VSMC) had a pathological pertinence. Conditioned media obtained from rat aorta smooth muscle cell (SMC) that were induced death by expressing FADD in the absence of tetracycline (FADD-SMC) triggered death of normal SMC. DNA fragmentation and caspase-3 activation were observed in dying SMC by conditioned media. FADD-SMC showed transcriptional activation of tumor necrosis factor (TNF)-α. Conditioned medium... -

Nitric oxide (NO) has been suggested to act as a mediator of cytokine-induced effects of turn over of bone. Activation of the inducible nitric oxide synthase (iNOS) by inflammation has been related with apoptotic cell death in osteoblast. YS 49, a synthetic isoquinoline alkaloid, inhibits NO production in macrophages activated with cytokines. In the present study, we investigated the molecular mechanism of YS 49 to inhibit iNOS expression in ROS 17/2.8 cells, which were activated with combined... -
알쯔하이머형 치매 환자의 단핵세포 증식과 싸이토카인 생성에 대한 β-아밀로이드 펩티드의 작용

SCC 12와 SCC 13 세포주는 피부의 상피암 조직에서 유래되었다. 본 연구에서는, 세포배양으로 in vivo 피부의 거의 모든 특징들을 재현할 수 있는 raft 배양법을 이용하여, 두 종류의 상피 암세포주의 진피 침투성 정도를 비교해 보았다. SCC 12 세포주의 raft 배양에서는, collagen matrix로 침투하는 많은 세포군들이 관찰되었고, 또한 기저세포와 유사한 세포들이 분화층 중간에 관찰되었다. 그러나 SCC 13 세포주의 raft 배양에서는 침투성 세포들이 전혀 관찰되지 않았다. 어떤 인자가 SCC 12 세포주의 침투성에 관여하였는지를... -

Hydroxyl raical(OH⋅)을 생성하는 것으로 알려진 iron-catalyzed Haber-Weiss rocation에서 superoxide anion (O2-⋅)은 주로 Fe+++을 Fe++로 환원시키는 데에 작용하는 것으로 추정하고 있다. 이러한 OH⋅ 의 역할은 다른 환원제들에 의하여 대체가 가능할 것으로 추측되며 생물계의 환원제의 하나로써 ascorbate가 관심의 대상이 되고 있다. 이에 따라 본 연구에서는 Fe++와 H2O2 존재하에서 OH⋅ 을 생성하는 ascorbate 의 역할을 hyaluronic acid의 변성과 methional로 부터 ethylene 생성에 대한 효과로써... -

대한생리학회 대한생리학회지 1995, 제 29권 제 1호 1 1-12 (12 pages)
Alveolar macrophages play a pivotal role in the pathogenesis of silicosis since the macrophages may release a wide variety of toxic and inflammatory mediators as well as mitogenic growth factors. In the present study, the effects of in vitro exposure to silica on release of various mediator such as reactive oxygen species, platelet activating factor(PAF), and interleukin-1 (IL-1) by alveolar macrophages were examined. First, hydrogen peroxide release from alveolar macrophages was monitored by... -

Knowledge of the concept of osseointegration has enhanced the success of dental implants owing to improved understanding of the concept of bone stress and bone response. Longitudinal clinical studies report 10-year successrates of 81-85% for implants in the maxilla and 98-99% for implants in the anterior mandible1). In 1989, the main causes of implant failure were the selection of inappropriate patients and the accumulation of residue owing to the use of improper prosthetic restoration...
