On the cover: Hematopoietic cancers, such as the follicular lymphoma pictured on the cover, frequently contain chromosomal translocations. However, the molecular mechanisms behind these DNA breakage and reshuffling events are largely unidentified. In this issue of Cell, Tsai et al. (pp. 1130–1142) show that CpG dinucleotides, like that colored in the molecular structure on the cover, are hotspots for pro-B/pre-B stage translocations—the most common translocations in human cancer. On the basis of the molecular activities occurring in pro-B/pre-B cells, they propose a theory to explain the apparent lineage specificity, stage specificity, and breakage at CpGs. The structure was adapted from PDB 3C2I and generated in UCSF Chimera. The histologic photo of the follicular lymphoma was a generous gift of Dr. Bharat Nathwani, USC.

- Basal cells make contact with lumen
- Rather than sitting passively in the basement of epithelial tissues, basal cells (red) are now seen to send slender extensions towards tight junctions (green) at the lumen. In the case of the epididymis as shown here in a 3D confocal reconstruction, these extensions seem to play an active role in the regulation of the tissue's activities in response to signals in the lumen that lead to the activation of apical V-ATP pumps (blue) of neighboring cells. Nuclei and spermatozoa are also shown in blue. See also paper by Shum et al.

Incompatibility of Nuclear and Mitochondrial Genomes Causes Hybrid Sterility between Two Yeast Species
Hybrid sterility is a phenomenon that often occurs when two species are crossed, but the resulting offspring is infertile. By screening hybrids of two yeast species, Lee et al. identify a pair of genes responsible for this hybrid incompatibility. The results reveal insights into the mechanism of mitochondrial and nuclear genome incompatibility as an important step in speciation. |
| In this PaperClip, Dr. Britta Mädge speaks with Dr. Jun-Yi Leu about his group’s identification of hybrid incompatibility genes in yeast.

In our latest podcast, we hear from Dr. Nathaniel Heintz about "TRAP," a new technique reported in Cell for looking at gene expression in the brain. Then we learn about a study in Current Biology from Dr. Robert Fleischer regarding the curious classification of the Hawaiian honeyeater. And we will also hear from Dr. Alan Beggs about his study in the American Journal of Human Genetics presenting a large-scale screen for mutations involved in Diamond-Blackfan anemia.
And stay tuned for a round-up of some of the exciting research advances recently published in Cell and the Cell Press family of journals. |
