Seleno-L-Methionine Modulation of Nucleotide Excision DNA Repair Relevant to Cancer Prevention and Chemotherapy.
Organic selenium compounds are known to prevent certain cancers although mechanisms may be complex. A widely-held view is that selenium compounds can induce apoptosis in cancer cells, or more precisely, in aberrant cells that are undergoing clonal evolution somewhere along the carcinogenesis process. There are at least 20 different selenium compounds, inorganic as well as organic, that have bee...
متن کاملSupplementary seleno-L-methionine suppresses active cutaneous anaphylaxis reaction.
To clarify the relationship between selenium supplementation and type I allergic reaction, we investigated the effect of seleno-L-methionine (SeMet) supplementation on the active cutaneous anaphylaxis (ACA) reaction and cytokine production in splenocytes. Female BALB/c mice were sensitized by intraperitoneal injection of ovalbumin (OVA), and SeMet was administered orally for 2 weeks followed by...
متن کاملDistribution and inhibition effect of Seleno-L-Methionine on 4T1 mouse mammary carcinoma.
To identify the relationship between selenium intake and breast cancer progression, SeMet supplement was applied to 4T1 murine mammary carcinoma for 28 days and the effect of SeMet on tumor growth was assessed. Combined with SXRF mapping, trace metal distribution in tumor tissues in relation to selenium-associated protein expressions and cellular transcription factors, HIF-1α accumulation and i...
متن کاملCrystal structure of seleno-l-cystine dihydrochloride
Numerous crystal structures are available for the dimeric amino acid cystine. In proteins it is formed by oxidation of the -SH thiol groups of two closely spaced cysteine residues, resulting in the formation of a familiar di-sulfide bridge. The title compound [systematic name: (R,R)-1,1'-dicarb-oxy-2,2'-(diselanedi-yl)diethanaminium dichloride], C6H14N2O4Se2 (2+)·2Cl(-), is the first example of...
متن کاملAuxin-binding proteins of Zea mays identified by photoaffinity labelling.
Auxins [indole-3-acetic acid (IAA) and related natural and synthetic analogues] are a group of phytohormones that influence fundamental growth and development responses in plants, e.g. cell elongation and cell division (see [l] for review). It is thought tht auxins are synthesized in apical meristems and move by polar transport to basal/subapical target tissues. The control of auxin concentrati...
