Abstract/OtherAbstract:
OBJECTIVE: To investigate the effects of nicotine in combination with okadaic acid (OA) or taxol on bovine oocyte maturation and subsequent embryonic development. DESIGN: Prospective randomized study. SETTING: University research laboratory. PATIENT(S): Bovine ovaries, oocytes, and embryos. INTERVENTION(S): Oocyte maturation and subsequent embryo development in the presence of nicotine in combination with okadaic acid and taxol. MAIN OUTCOME MEASURE(S): Haploid composition, cleavage rate, IVF and parthenogenetic embryo development, blastocyst cell number. RESULT(S): The results showed that nicotine and OA or nicotine and taxol significantly decreased oocyte maturation rates. Combinations of nicotine (10 or 50 micromol/L) and OA (0.01 or 0.05 micromol/L) did not affect oocyte haploid composition; however, taxol alone or combined with nicotine caused a decrease in haploid composition compared with control. Parthenogenetic activation of oocytes that were matured in nicotine, OA, or taxol resulted in blastocyst development rates of 12%-17%, which were not different from the control. Various combinations of nicotine and OA or nicotine and taxol significantly lowered (3%-8%) blastocyst development compared with control. The average cell number of blastocysts derived from nicotine + OA- and nicotine + taxol-treated oocytes was lower than all other treatment groups and control. For oocytes fertilized in vitro, oocytes matured in OA, taxol, or combinations of nicotine and OA or taxol-containing media resulted in significantly lower cleavage rates and blastocyst development compared with the control group and the 10 micromol/L nicotine treatment group. The IVF embryos cultured in nicotine + OA-containing medium had a significantly lower blastocyst development rate. CONCLUSION(S): Combinations of nicotine with OA or taxol adversely affect oocyte maturation and subsequently result in poor blastocyst development.
