Head and neck carcinomas are among the most frequent tumor types worldwide and the most common variant is the squamous cell carcinoma from the upper aerodigestive tract (HNSCC). Genetic alterations in tumor suppressor genes increase the risk of tumor development, since these genes are associated with cycle cell control. Epigenetic changes involving cell cycle regulatory genes are related to the initiation...
The location of chromosomal telomeric repeats (TTAGGG)n was investigated in two species of the Molossidae family, Eumops glaucinus and Eumops perotis. The diploid chromosome number (2n) is 40 in E. glaucinus and 48 in E. perotis and the fundamental numbers (FN) are 64 and 58, respectively. It has been suggested that the E. glaucinus karyotype has evolved from the E. perotis karyotype through Robertsonian...
