Context: Heat shock protein-27 (HSP-27) belongs to the group of small heat shock proteins that become induced in response to various pathologic conditions. HSP-27 has been shown to protect cells and subcellular structures, particularly mitochondria, and serves as a carrier for estradiol. It is a reliable marker for tissues affected by oxidative stress. Oxidative stress and related cellular defence mechanisms are currently thought to play a major role during experimentally induced epileptic neuropathology. We addressed the question whether HSP-27 becomes induced in the neocortex resected from patients with pharmacoresistant epilepsy.', "Human epileptic temporal neocortex was obtained during neurosurgery, and control tissue was obtained at autopsy from subjects without known neurologic diseases. The tissues were either frozen for Western blot analysis or fixed in Zamboni's fixative for the topographic detection of HSP-27 at the cellular level by means of immunohistochemistry.", 'HSP-27 was highly expressed in all epilepsy specimens and in the cortex of a patient who died in the final stage of multiple sclerosis (positive control), whereas only low amounts of HSP-27 were detectable in control brains. In epilepsy patients, HSP-27 was present in astrocytes and in the walls of blood vessels. The intracortical distribution patterns varied strongly among the epilepsy specimens.
Answer: These results demonstrate that HSP-27 becomes induced in response to epileptic pathology. Although the functional aspects of HSP-27 induction during human epilepsy have yet to be elucidated, it can be concluded that HSP-27 is a marker for cortical regions in which a stress response has been caused by seizures.
Is heat shock protein-27 upregulated in the temporal cortex of patients with epilepsy?

Context: Increased concentrations of metalloproteinases are associated with the invasive and metastatic behavior of several human malignant tumors. Normally, enzymatic activity is tightly regulated by nonspecific mechanisms and specific inhibitors. The aim of the study was to determine the potential of a synthetic metalloproteinase inhibitor, batimastat, to show its in vitro effect on MatLyLu cancer cells and its in vivo effect on tumor growth in orthotopic cancer (R3327 Dunning tumor) in rats.', 'In vitro, a dose response curve of batimastat was generated over 4 days using the MTT assay. Prostate cancer was injected in vivo in male Copenhagen rats by inoculating R3327 Dunning tumor cells (MatLyLu) into the ventral prostatic lobe of 30 rats. Each of 10 rats received batimastat (30 mg/kg body weight) or vehicle administered once a day by i.p. application beginning the day of cell inoculation. Ten rats remained untreated. The effect on local tumor growth was evaluated by measuring tumor weights 20 days after tumor cell inoculation.', 'Significant inhibition of tumor cell proliferation in vitro occurred at 400 and 4,000 ng/ml batimastat. After orthotopic cell inoculation, tumors grew to mean weights of 18.9 g in the control group without treatment, to 22.3 g in the vehicle group, and to 11.1 g in the treated group. In comparison to the control group and to the vehicle group, tumor weights increased significantly less under treatment with batimastat.
Answer: Batimastat is able to reduce tumor growth in the standard prostate cancer model. Using this model, activity against cancer progression of future inhibitory agents can be reliably assessed.
Does synthetic inhibitor of matrix metalloproteinases ( batimastat ) reduce prostate cancer growth in an orthotopic rat model?

Context: Studies have revealed a phenomenon called skin-deep resilience, which develops in upwardly mobile African American youth. They perform well in school, maintain good mental health, and avoid legal problems. Despite outward indications of success, they also show evidence of worse health in biomarker studies. Here we extend this research, asking whether it manifests in differential susceptibility to upper respiratory infection, and if it emerges in European Americans as well.', 'The sample included 514 adults in good health, as judged by physician examination and laboratory testing. Participants completed questionnaires about lifecourse socioeconomic conditions, conscientiousness, psychosocial adjustment, and lifestyle factors. They were subsequently inoculated with a rhinovirus that causes upper respiratory infection, and monitored in quarantine for 5 days the development of illness.', "Consistent with past work, African Americans from disadvantaged backgrounds displayed indications of skin-deep resilience. To the extent these participants were high in conscientiousness, they fared better across multiple domains of psychosocial functioning, as reflected in educational attainment, symptoms of depression, and close relationship quality (p values = .01-.04). But analyses of these participants' susceptibility to infection revealed the opposite pattern; higher conscientiousness was associated with a greater likelihood of becoming ill following inoculation (p value = .03). In European Americans, there was no evidence of skin-deep resilience; conscientiousness was associated with better psychosocial outcomes, but not infection risk.
Answer: These observations suggest that resilience may be a double-edged sword for African Americans from disadvantaged backgrounds. The same characteristics associated with academic success and psychological adjustment forecast increased vulnerability to health problems. (PsycINFO Database Record
