  • Two types of normal human breast epithelial cells (HBECs) have already been established and characterized. Type I HBECs are deficient in gap junctional intercellular communication and are capable of anchorage-independent growth and of expressing luminal epithelial cell markers, a variant estrogen receptor (ER), and stem cell characteristics.(omitted)

  • 녹색식물과 같이 독립영양생물이 빛에너지를 이용하여 $CO_2$와 물로 탄수화물을 만드는 일련의 반응을 광합성이라 한다. 그 일련의 반응 중에서(그림 1) 반응 I과 II는 틸라코이드(thylakoid)에서, 반응 III은 스트로마(stroma)에서, 반응 IV는 엽록체내와 세포질에서 일어나는 반응의 상호작용에 의하여 나타난다. 과거에는 반응 I과 II를 명반응, 반응 III과 IV를 암반응이라 부르기도 하였다.(중략)

  • The purpose of this paper is to develop a procedure and a system for the design of manufacturing cells. First, a procedure is developed to create machine cells, to identify part families and to allocate part families to machine cells so that the intercellular movement of part is minimized. Next, a system for solving this procedure is developed and an application example is demonstrated.

  • This Paper proposes a mathematical model to solve the cell formation problem with exceptional elements, Exceptional elements are bottleneck machines and exceptional parts that span two or more manufacturing cells. The model suggests whether it is cost-effective to eliminate an EE (by machine duplication or part subcontracting), or whether the intercellular transfer caused by the EE should remain in the cell formation. It provides an optimal solution for resolving the interaction created by EE in the initial cell formation solution. In addition, the model recognizes potentially advantageous mixed strategies ignored by previous approaches.

  • Cell-cell and cell-matrix interaction is clearly required for metazoans not only to hold their cells together but also to conduct more sophisticated biological processes. Each cell has adhesion molecules on its cell membrane to link extracellular matrix and adjacent cells to the intracellular cytoskeleton, and also to transduce signals. In complex metazoans, information is transmitted from one cell to another by mechanisms such as direct intercellular communication, soluble signal molecules among distant cells, and local cellular environments formed by highly specialized extracellular matrix.

  • Since radiotherapy has been suspected to promote tumor metastasis and the presence of increase levels of adhesion molecules have implications for metastasis, we decided to investigate whether gamma-irradiation alters the expression of intercellular adhesion molecule-1 (ICAM-1) on neuroblastoma cells and the activities of relevant intracellular signaling molecules. In the present study, the relative of ICAM-1 expression under gamma-irradiated neuroblastoma cells were assessed by Western blot analysis. (omitted)

  • TCTP is presented to have a retinol binding protein (RBP)-like structure by domain search. Human cellular RBP (CRBP) plays a key role in the intercellular transfer of retinol. Modulation of its expression is known to contribute to tumor growth and progression via retinoid-mediated signaling. Changes in the expression of TCTP have also been reported to be associated with carcinogenesis. Therefore, the attempt to establish the interactive relationship between the human TCTP and CRBP with retinol will be helpful in further understanding the cell signaling of TCTP. (omitted)
