Viral killer

By | August 31, 2001

The ability to selectively kill cells lacking normal p53 activity is an attractive anti-cancer strategy. In the August 30 Nature, Kenneth Raj and colleagues from the Swiss Institute for Experimental Cancer Research (ISREC) suggest that adeno-associated virus (AAV) could be employed as a 'hired assassin' (Nature 2001, 412:914-917).They found that AAV induced apoptosis of p53-deficient osteosarcoma cells, but induced cell-cycle arrest (in G2 phase) in cells expressing p53. None of the proteins enc

Regulating p53

By | August 29, 2001

MDM2 is an E3 ubiquitin ligase that regulates the activity of p53 by controlling degradation of the p53 protein, as a result of differential addition of ubiquitin. In the Advanced Online Publication of Nature Genetics, Parant et al. report the phenotype of mice lacking the recently cloned MDM2-related protein MDM4 (DOI:10.1038/ng714).They show that mdm4-null mice die at embryonic day 7.5-8.5. Analysis of the incorporation of the nucleotide analogue BrdU and TUNEL staining for apoptotic cells sho

Consequences of patrilocality

By | August 28, 2001

Patrilocality (in which a woman moves to her mate's residence upon marriage) and matrilocality (in which women stay put and the men move) should be reflected in intra- and inter-group differences in the diversity of Y-chromosome and mitochondrial DNA sequences, inherited from the father and mother, respectively. In the Advance Online Publication of Nature Genetics, Oota et al. put this to the test by comparing Y-chromosome and mtDNA diversity in three matrilocal and three patrilocal tribes in no
