The Transcription Factor Hey and Nuclear Lamins Specify and Maintain
RESEARCH ARTICLE The transcription factor Hey and nuclear lamins specify and maintain cell identity Naama Flint Brodsly1†, Eliya Bitman-Lotan1†, Olga Boico1, Adi Shafat1, Maria Monastirioti2, Manfred Gessler3, Christos Delidakis2, Hector Rincon-Arano4, Amir Orian1* 1Rappaport Research Institute and Faculty of Medicine, Technion-Israel Institute of Technology, Haifa, Israel; 2Institute of Molecular Biology and Biotechnology (IMBB), Foundation for Research and Technology - Hellas (FORTH), Heraklion, Greece; 3Biocenter of Developmental Biochemistry, University of Wu¨ rzburg, Wu¨ rzburg, Germany; 4Division of Basic Sciences, Fred Hutchinson Cancer Research Center, Seattle, United States Abstract The inability of differentiated cells to maintain their identity is a hallmark of age- related diseases. We found that the transcription factor Hey supervises the identity of differentiated enterocytes (ECs) in the adult Drosophila midgut. Lineage tracing established that Hey-deficient ECs are unable to maintain their unique nuclear organization and identity. To supervise cell identity, Hey determines the expression of nuclear lamins, switching from a stem-cell lamin configuration to a differentiated lamin configuration. Moreover, continued Hey expression is required to conserve large-scale nuclear organization. During aging, Hey levels decline, and EC identity and gut homeostasis are impaired, including pathological reprograming and compromised gut integrity. These phenotypes are highly similar to those observed upon acute targeting of Hey or perturbation of lamin expression in ECs in young adults. Indeed, aging phenotypes were suppressed by continued expression of Hey in ECs, suggesting that a Hey-lamin network *For correspondence: safeguards nuclear organization and differentiated cell identity.

For both of these uses, a transposon with minimal insertion bias is desired to allow complete coverage with minimal oversampling. Findings: Three transposons, Mu, Tn5, and Tn7, were used to generate insertions in the same set of fosmids containing Candida glabrata genomic DNA. -

The Lamarckian Chicken and the Darwinian Egg Yitzhak Pilpel1* and Oded Rechavi2*
Pilpel and Rechavi Biology Direct (2015) 10:34 DOI 10.1186/s13062-015-0062-9 COMMENT Open Access The Lamarckian chicken and the Darwinian egg Yitzhak Pilpel1* and Oded Rechavi2* Abstract: “Which came first, the Chicken or the Egg?” We suggest this question is not a paradox.

It was previously shown that DNA double strand breaks in the 5 chromosome stimulate Tn7 transposition where transposition events occur 6 broadly around the point of the DNA break. We show that individual DNA breaks 7 actually activate a series of small regional hotspots in the chromosome for Tn7 8 insertion. These hotspots are fixed and only become active when a DNA break 9 occurs in the same region of the chromosome. -
