Resveratrol reduces cerebral edema through inhibition of de novo SUR1 expression induced after focal ischemia.

Cerebral edema is a clinical problem that frequently follows ischemic infarcts. Sulfonylurea receptor 1 (SUR1) is an inducible protein that can form a heteromultimeric complex with aquaporin 4 (AQP4) that mediate the ion/water transport involved in brain tissue swelling. Transcription of the Abcc8 gene coding for SUR1 depends on the activity of transcriptional factor SP1, which is modulated by the cellular redox environment.

Incidence and Risk Factors of Dry Eye in a Spanish Adult Population: 11-Year Follow-Up From the Salnés Eye Study.

Purpose: To estimate the incidence of dry eye (DE) and to evaluate risk factors in an adult cohort in Spain.

Methods: The Salnés Eye Study (SES) was a cross-sectional population-based study of 654 subjects conducted from 2005 to 2006. After 11 years, 264 individuals (65.

Role of LOXs and COX-2 on FAK activation and cell migration induced by linoleic acid in MDA-MB-231 breast cancer cells.

Background: Epidemiological studies and animal models suggest a link between high levels of dietary fat intake and an increased risk of developing breast cancer. Particularly, free fatty acids (FFAs) are involved in several processes, including proliferation, migration and invasion, in breast cancer cells. Linoleic acid (LA) is a dietary n-6 polyunsaturated fatty acid that is known to induce proliferation and invasion in breast cancer cells.

Apoptosis-inducing factor and colon cancer.

Programmed cell death is a fundamental requirement for embryogenesis, organ metamorphosis, and tissue homeostasis. Since the vast majority of cytotoxic modalities exert their anti-tumor effects by induction of apoptosis, programmed cell death has emerged as a potential target for cancer treatment at various stages of tumor progression. Immuno-regulation and chemoradiosensitization are potential pathways where insight in apoptotic mechanisms may lead to improvement of chemoradiotherapeutic modalities.

Alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors signaling complexes in Bergmann glia.

Glutamate, the major excitatory neurotransmitter, induces a wide array of signals from the membrane to the nucleus regulating gene expression. In Bergmann glia, Ca2+ -permeable alpha-amino-3-hydroxy-5-methyl-4-isoxazole- propionic acid (AMPA) receptors are involved in the short- and long-term interactions between these cells and the neurons that they surround. After activation, AMPA receptors become tyrosine phosphorylated and by these means form multiprotein signaling complexes.
