چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
15 صفحه اولNew Data on the Genetics of Polymorphism in the Snail Cepaea Nemoralis L.
A REVIEW of the remarkable polymorphism in the European land snail Cepaea nemoralis L. and of the various interpretations based on it has been given in a previous issue of this journal (CAIN and SHEPPARD 1954). Since the adaptive and evolutionary significance of the polymorphism is the subject of active research, a considerably better knowledge of its genetics is desirable. Subsequently, LAMOTT...
متن کاملHistory or current selection? A molecular analysis of 'area effects' in the land snail Cepaea nemoralis.
We have used molecular variation in microsatellite and mitochondrial DNA to throw light on the origins of enigmatic geographical patterns, known as 'area effects', in the shell polymorphisms of the land snail Cepaea nemoralis. Our aim was to assess the relative importance of recent selection and historical events in the formation of these patterns. On the Marlborough Downs in Wiltshire, England...
متن کاملRain Events Influence Short-term Feeding Preferences in the Snail Cepaea Nemoralis
Terrestrial gastropods are both herbivores and detritivores, but the ratio between these two modes of feeding can be highly variable over time. While previous studies have examined long-term seasonal patterns in the consumption of fresh material, mechanisms explaining short-term variation in dietary preferences have not been explored. We used faecal analysis to determine how short-term variatio...
متن کاملThe inheritance of some characters in Cepaea hortensis and Cepaea nemoralis (Gastropoda).
N recent years the remarkable polymorphism of snails of the genus Cepaea IHeld has continued to attract considerable attention. The variation from place to place in the proportions of the different phenotypes has proved to be useful material for the study of evolution in natural populations (CAIN and SHEPPARD 1950, 1954; CLARKE 1960; CLARKE and MURRAY 1962; LAMOTTE 1951, 1959; SCHNETTER 195 1 ;...
