Oncogene-like addiction to aneuploidy in human cancers

V. Girish, A. A. Lakhani, C. M. Scaduto, S. L. Thompson, L. M. Brown, R. A. Hagenson, E. L. Sausville, B. E. Mendelson, D. A. Lukow, M. L. Yuan, P. K. Kandikuppa, E. C. Stevens, S. N. Lee, B. Salovska, W. Li, , J. M. Sheltzer

This study demonstrates that trisomy of chromosome 1q is essential for malignant growth in cancers and shows that TP53 mutations are mutually exclusive with 1q aneuploidy.

microRNA-triggered transposon small RNAs mediate genome dosage response

F. Borges, J.-S. Parent, F. van Ex, P. Wolff, G. Martinez, C. Kohler, R. A. Martienssen

The paper shows that miR845 targets transposon PBS in Arabidopsis pollen, triggering small RNA accumulation that mediates hybridization barriers and endosperm balance.
