Even less is known about its-.oo However, the effectsof-have not been investigated thoroughly.oo -has never been satisfactorilyexplained.oo Although many studies of -have been reported and it is well establishedthat EM do produce melanin in vivo, little is known about melanogenesis by A.oo Little work has been performed on melanogenesis by A in vitro.oo Investigation of melanogenesis by A in vitro has been hampered by aninability to obtain a sufficient number of pure A for study.oThe role of the iris in normal function and in disease remains to beelucidated.o 仍有争议oo -remains controversial.oo Whether A produce melanin in vivo during adulthood remains controversial.oThe literature about the sth remains scant.o 新进展oo Sb has developed and report here new methods for Aoo We have developed methods for Aoo Recent advances in techniques of- suggested-oo Recently, it has been found that melanin from the uvea could stimulate A1and may be involved in the pathogenesis of A2 and the A3.oWe have developed methods for isolation and culture of A.o 保护作用oOcular pigmentation, particularly -, may play an important protectiverole in prevention of these diseases.o 研究目的oo The purpose of the present study was to investigate melanogenesis by A invitro.oo We wanted to explore specifically whether A produce melanin in vitro,whether melanin content and melanin production by A in vitro correlate withiris pigmentation, whether cultured A express - activity, and whether -activity of A correlates with -, - and -.oWe also wanted to study factors influencing melanin content andproduction, as well as the -activity of A in vitro.o 比较分析oo Recently epidemiological and molecular biological studies indicate that A1is different from A2 and similar to A3, e.g., the occurrence of A1 is relatedto the sunlight exposure and mutation of BRAF gene, whereas the C2 are not.oo The difference between the A1 and A2 may be determined by the differentenvironmental and cellular factors of the C1 and C2.oo These results indicated that X only stimulated cell growth at a highconcentration.oo After supplementation with X, A growth was stimulated, but mitoticactivity declined rapidly after a few passages.oThese effects were dose-dependent at the range from - to - Mo 统计学oo The differences of X and cell counts between the control and test groupswere statistically significant (cell number: 0.05 P0.01 atconcentrations of -M in complete medium, at - M in - medium, and P0.01 at concentrations of - M in - medium).oo The differences between the X treated culture and negative controls weresignificant at concentrations of 10-6-10-5 Moo In the study on/(of the) cAMP-deleted medium, the number of cellsincubated with X at all concentrations showed no significant differencecompared with the negative controls.oThis method provi
