جون بيتنر
جون جوسف بيتنر John Joseph Bittner (25 فبراير 1904 - 14 ديسمبر 1961)، عالم جينات وبيولوجيا سرطان، له اسهامات عديدة في أبحاث علم جينات سرطان الثدي، والتي لم تقتصر فائدتها على أبحاث السرطان، بل على أبحاث بيولوجية أخرى.
وقد تمكن من عزل "Bittner milk factor" (1949) من لبن نوع معين من الفئران، والذي أشار بقوة إلى أنه على الأقل بعض الفيروسات يمكنها التسبب في الاصابة بالسرطان. وباستخدام Using carefully bred strains of mice, he compared the role of the mother's genetic disposition to be either prone to cancer or resistant. By having the mice of one disposition act as foster mothers and nurse the babies of the other disposition, he showed that cancer-prone young could grow to be cancer resistant. The opposite was also true: babies originally cancer-resistant became cancer prone. He published this observation (1936), and went on to isolate particles of a virus-like size from the milk of cancer-prone mice that were not present in the milk of cancer-resistant mice. 6,000 م³
