Analytical, diagnostic and therapeutic context of PTGS1

  • METHODS: Northern blot analysis was used to quantify COX-1 and COX-2 mRNA expression in primary cultures of bovine chondrocytes and prostaglandin production to evaluate COX activity [30].
  • The time- and concentration-dependent induction of COX-2 expression in the BAECs was evaluated by a kinetic profile (HPLC analysis) and detected by Western-Blot analysis using polyclonal antibodies against COX-1 and COX-2 [15].
  • COX-1 and COX-2 gene and protein expression were examined by RT-PCR and Western analysis, respectively; prostanoid measurements were made by gas chromatography-mass spectrometry, and COX activity was studied after a 30-min incubation with 30 microM arachidonic acid [31].
  • After detergent extraction, the enzyme had hydrodynamic properties indistinguishable from native bovine COX-1 and corresponded to the enzyme dimer as measured with size-exclusion chromatography [32].
  • Their effect was quantified by measurement of PGE(2) and PGF(2alpha) production by ELISA and induction of cyclooxygenase (COX-2) by Western and Northern analysis and correlated with antiviral activity previously reported [33].
