Gene loss in human teratomas.
If benign cystic teratomas (dermoid cysts) of the ovary arise from a germ cell that has undergone meiosis, they should be missing genes which are present in the person. Three independently segregating allelic isozymes in 11 benign cystic teratomas of the human female ovary were compared with normal tissue of the same case. Dermoid cysts from persons heterozygous for these isozymes are frequentl...
متن کاملTeratomas.
Teratomas are embryonal tumors that normally arise from germ cells [3] and are typically benign. They are defined as being composed either of tissues that are foreign to the area in which they form, or of tissues that derive from all three of the germ layers [4]. Malignant teratomas are known as teratocarcinomas; these cancerous growths have played a pivotal role in the discovery of stem cells ...
متن کاملCystic teratomas of the pancreas.
Cystic teratomas of the pancreas constitute an extremely rare entity with only nine cases, to our knowledge, described in the world literature. Symptoms are usually due to the compressive effects of the tumor on the neighboring organs. They should be considered in the differential diagnosis of slow-growing benign pancreatic cysts. We describe a 25-year-old woman with a pancreatic teratoma who w...
متن کاملPrimary mediastinal trophoblastic teratomas.
Three cases of primary mediastinal trophoblastic teratoma are described. One patient died from respiratory failure during the initial chemotherapy, Another patient with advanced disease is now apparently free from disease after multiple-drug chemotherapy.

متن کاملES cells without teratomas
Transport if loaded uclear transporters can be viewed as taxis that move cargo across the nuclear envelope. On page 649, Plafker et al. report that importin-11, a nuclear transport receptor , may be an especially selective cabbie. Importin-11 transports UbcM2, a ubiquitin (Ub)-conjugating enzyme, but it does so only when the enzyme is charged with a Ub at its active site. UbcM2 is an E2 enzyme,...
