The family Bathyergidae, or African mole-rats (including the well-known naked mole-rat), belong to the other major division of the rodents, the hystricomorphs. [ citation needed ] All the rhizomyines are bulky, slow-moving, burrowing animals, the Rhizomys species being the largest and stockiest.
The film profiles four subjects with extraordinary careers: Dave Hoover, a wild-animal tamer; George Mendonça, a topiary gardener at Green Animals Topiary Garden in Portsmouth, Rhode Island; Ray Mendez, an expert on naked mole-rats who has designed an exhibit on the animals for the Philadelphia Zoo; and Rodney Brooks, an MIT scientist who works in robotics.

Similarly, in drug resistance development, it has been suggested that epigenetic modifications can result in the activation and overexpression of pro-drug resistance genes. [12] Studies on cancer cell lines have shown that hypomethylation (loss of methylation) of the MDR1 gene promoter caused overexpression and the multidrug resistance. [13]
Mole-rat or mole rat can refer to several groups of burrowing Old World rodents: Bathyergidae, a family of about 20 hystricognath species in six genera from Africa also called blesmols. Heterocephalus glaber, the naked mole-rat. Spalacidae, a family of about 30 muroid species in six genera from Eurasia and northeast Africa, including:
