Identification of the responsible proteins for increased selenium bioavailability in the brain of transgenic rats overexpressing selenoprotein M.
Seoul, South Korea. In Int J Mol Med, 31 Dec 2014
The results revealed that: ⅰ) CMV/hSelM Tg rats showed a high level of enzyme activity for antioxidant protein in the brain cortex compared to non‑Tg rats; ⅱ) the high activity of these enzymes induced a decrease in total antioxidant concentration and γ‑secretase activity in CMV/hSelM Tg rats; ⅲ) five proteins were upregulated and three were downregulated by SelM overexpression; ⅳ) among the five upregulated proteins, two associated with creatine kinase B‑type (B‑CK) and E3 ubiquitin‑protein ligase RING1 (RING finger protein 1) were further increased in the two groups following Sel treatment, whereas synaptotagmin-15 (SytXV), eukaryotic translation initiation factor 4H (eIF-4H) and lactate dehydrogenase B (LDH-B) were increased or decreased under the same conditions; ⅴ) the three downregulated proteins did not induce a significant change in expression following Sel treatment; and ⅵ) the protein expression level alterations of the two selected spots (B‑CK and SytXV) identified by 2‑DE were extremely similar to the results from western blot analysis.
In vivo substrates of the lens molecular chaperones αA-crystallin and αB-crystallin.
Saint Louis, United States. In Plos One, Dec 2013
Compared with age-matched wild type lenses, 2-day-old αA-R49C heterozygous lenses demonstrated the following: increased crosslinking (15-fold) and degradation (2.6-fold) of αA-crystallin; increased association between αA-crystallin and filensin, actin, or creatine kinase B; increased acidification of βB1-crystallin; increased levels of grifin; and an association between βA3/A1-crystallin and αA-crystallin.

Tianjin, China. In Neural Regen Res, Dec 2013
These detected proteins included dihydropyrimidinase-related protein 2, creatine kinase B-type, isovaleryl-CoA dehydrogenase, elongation factor Ts, ATP synthase beta-subunit, 3-mercaptopyruvate sulfurtransferase, electron transfer flavoprotein alpha-subunit, Chain A of 2-enoyl-CoA hydratase, NADH dehydrogenase iron-sulfur protein 8 and tropomyosin beta chain.
Neuronal toxicity of efavirenz: a systematic review.
Stellenbosch, South Africa. In Expert Opin Drug Saf, Nov 2013
Several potential mechanisms exist to explain the observed efavirenz neurotoxicity, including altered calcium hemostasis, decreases in brain creatine kinase, mitochondrial damage, increases in brain proinflammatory cytokines and involvement of the cannabinoid system.
