Spontaneous canine mammary tumorigenesis seemed to be associated with increased secretory activity of growth hormone rather than prolactin cells. Depressed secretory activity of follicle stimulating hormone-, luteinizing hormone- and thyrotrophin-producing cells, as well as signs of inhibition of ovarian (anovulation) and thyroid function, were also consistent findings in dogs with mammary tumours. There also was disturbance in pituitary-adrenal function associated with hyperplastic and neoplastic changes of the pituitary gland and adrenal cortex.<\/jats:p>","DOI":"10.1177\/030098588001700101","type":"journal-article","created":{"date-parts":[[2017,1,11]],"date-time":"2017-01-11T17:34:22Z","timestamp":1484156062000},"page":"2-16","source":"Crossref","is-referenced-by-count":17,"title":["The Role of the Pituitary Gland in Spontaneous Canine Mammary Tumorigenesis"],"prefix":"10.1177","volume":"17","author":[{"given":"M.
