Abstract

To investigate the effect of disintegrin echistatin on integrin linked kinase (ILK) and subsequent PI3-K/Akt and ERK1/2 signaling pathways in the posterior capsule opacification (PCO) model of diabetic rabbit. 56 rabbits were injected alloxan to model diabetic. Then they accepted lens extraction surgery and randomly and intraoperatively injected distilled water (control group; n = 28) or 10.0 mg·L(-1) echistatin (echistatin-treated group; n = 28) into the anterior chamber. Each group was subdivided into ten days group (n = 14) and six weeks group (n = 14) respectively. The PCO severity was evaluated with a slit lamp microscope and light microscope for 10 days and 6 weeks postoperatively. The levels of ILK in the posterior capsule were determined by Q-PCR, Western blotting and Immunohistochemistry. Akt and ERK1/2 phosphorylation were analyzed by Western blotting. 10 days and 6 weeks after surgery, the grades of PCO in the echistatin-treated group were lower than the control group. The lens epithelial cells (LECs) in the posterior capsule of echistatin-treated eyes had decreased degrees of proliferation and migration than the control group. And no significant side effects appeared after treated with echistatin. Echistatin could s...Continue Reading

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
