  • Ultraviolet A regulates the stemness of human adipose tissue-derived mesenchymal stem cells through downregulation of the HIF-1α via activation of PGE(2)-cAMP signaling.
  • Lee J, Jung E, Hyun JW, Park D.Author information Department of Dermatological Health Management, Eul-Ji University, Seongnam City, 461-713 Gyunggi Do, Republic of Korea.AbstractUltraviolet A (UVA) irradiation is responsible for a variety of changes in cell biology. The purpose of this study was to investigate the effects of UVA irradiation on the stemness properties of human adipose tissue-derived mesenchymal stem cells (hAMSCs). Furthermore, we examined the UVA-antagonizing effects of L-cysteine ethylester hydrochloride (ethylcysteine) and elucidated its action mechanisms. The results of this study showed that UVA reduced the proliferative potential and stemness of hAMSCs, as evidenced by reduced proliferative activity in the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and downregulation of OCT4, NANOG, and SOX2, stemness-related genes. The mRNA level of hypoxia-inducible factor (HIF)-1α, but not HIF-2α was reduced by UVA. Moreover, the knockdown of HIF-1α using small interfering RNA (siRNA) for HIF-1α was found to downregulate stemness genes, suggesting that UVA reduces the stemness through downregulation of HIF-1α. In addition, we examined the mechanisms underlying the UVA-mediated effects and found that UVA induced production of prostaglandin (PG) E2 and 3'-5'-cyclic adenosine monophosphate (cAMP), and that this effect was mediated through activation of activating protein-1 (AP-1) and nuclear factor-κB (NF-κB). The UVA effects were antagonized by ethylcysteine, and the effects were found to be mediated by reduced production of PGE2 through the inhibition of JNK and p42/44 MAPK. Taken together, these findings show for the first time that UVA regulates the stemness of hAMSCs and its effects are mediated by downregulation of HIF-1α via the activation of PGE(2)-cAMP signaling. In addition, ethylcysteine may be used as an antagonizing agent to mitigate the effects of UVA.

  • Biological properties of kinin-releasing enzyme from Trimeresurus okinavensis (himehabu) venom.
  • Nikai T, Komori Y, Kato S, Sugihara H.Author information Faculty of Pharmacy, Meijo University, Nagoya, Japan. nikai@meijo-u.ac.jpAbstractA kinin-releasing enzyme was isolated and characterized from the venom of Trimeresurus okinavensis (himehabu) using Sephadex G-100, DEAE-Cellulose, and CM-Cellulose column chromatographies. The kinin-releasing enzyme was homogeneous as demonstrated by a single band on polyacrylamide gel electrophoresis, and isoelectric focusing. The enzyme possesses a molecular weight of 31,000 Da and isoelectric point of 8.2 and consists of 312 total amino acid residues. Specific esterolytic activities of the kinin-releasing enzyme on N-tosyl-L-arginine methyl ester (TAME) and N-benzoyl-L-arginine ethylester (BAEE) were determined to be 235.3 and 111.3 mumol/min/mg, respectively. The enzyme was inhibited by p-APMSF (p-amidinophenylmethanesulfonyl fluoride hydrochloride) and benzamidine. Additionally, the enzyme was found stable to heat treatment. The enzyme cleaved a kininogen analog with the release of bradykinin, resulting in an immediate drop in blood pressure, and contractions of the rat uterus were also observed.

  • Effect of cysteine ethylester hydrochloride (Cystanin) on host defense mechanisms (V): Potentiation of nitroblue tetrazolium reduction and chemiluminescence in macrophages or leukocytes of mice or rats.
  • Hisadome M, Fukuda T, Terasawa M.Author information Research Laboratories, Yoshitomi Pharmaceutical Industries, Ltd., Fukuoka, Japan.AbstractL-Cysteine ethylester hydrochloride (Cystanin, ethylcysteine) at doses of 3-30 mg/kg, p.o., potentiated the reduction of nitroblue tetrazolium (NBT) by mouse peritoneal macrophages ex vivo. In in vitro experiments, this drug (30 microM) augmented NBT reduction of mouse peritoneal macrophages induced by opsonized zymosan (OZ). At the same concentration, this drug accelerated the enhancement of the OZ-induced NBT reduction by the addition of concanavalin A, N-formyl-L-methionyl-L-leucyl-L-phenylalanine or phorbol myristate acetate. This enhancing effect of ethylcysteine was completely diminished by the addition of SOD, sodium azide and catalase. In ex vivo experiments, the OZ-induced chemiluminescence of rat peritoneal macrophages and white blood cells was enhanced by the administration of ethylcysteine at doses of 3-10 mg/kg (i.p.) and 3-30 mg/kg (p.o.). In addition, this drug significantly enhanced the lumisphere-induced chemiluminescence of rat peritoneal leukocytes at 30 mg/kg (i.p.), but not the OZ-induced chemiluminescence. In in vitro experiments, this drug (30 microM) did not enhance the OZ-induced chemiluminescence response of rat peritoneal macrophages. These results suggest that ethylcysteine may enhance the intracellular generation of antimicrobial oxidants in macrophages and leukocytes.
