Oral Carcinoma in a Monkey Colony

چکیده
A search of the literature discloses the extreme rari ty of oral carcinomas in domesticated and captive wild animals. Only 15 cases of carcinoma of the tongue in domesticated animals (horse, cow, cat, dog) reported from various countries have come to our a t tent ion (14). The autopsy records of the 10,298 mammals and birds tha t died in the Philadelphia Zoological Garden during a period of about 30 years show that only one animal, a male bear, with a carcinoma of the tongue was found (11). As far as subhuman primates are concerned, the incidence of neoplastic diseases, according to Ratcliffe, has been and still is lower in the Philadelphia Zoological Garden than for any comparable group of mammals (12), and until 1947 no carcinomas of the tongue in monkeys were discovered (13). Nor have we seen any references to malignant neoplasms of the tongue in autopsy reports issued from other laboratories and zoological gardens in which monkeys have come to autopsy. The occurrence of 2 additional oral carcinomas in our laboratory colony of monkeys is of particular interest not only because of the previous occurrence of 3 carcinomas of the tongue in 2 other monkeys of the same colony (14), but also because the 2 cases to be reported involve different sexes and different divisions of the suborder Pithecoidea. Furthermore, we believe that the information available on these animals and on the environmental conditions under which the disease occurred is somewhat more detailed than is usually the case in studies of monkeys that have died in laboratories or menageries.

Background: Oral squamous cell carcinoma is the sixth most common malignancy in the world today. ING1b/p33 is a newly-discovered tumor suppressor which enhances p53 activity. Transfer of p33 protein from nucleus to cytoplasmic compartment has been previously reported in leukemias. The objective of this study was to determine the correlation between p33ing1b cytoplasmic transfer and lymph node ...
