  1. Meng X, Brodsky M, Wolfe S. A bacterial one-hybrid system for determining the DNA-binding specificity of transcription factors. Nat Biotechnol. 2005;23:988-94 pubmed
    ..Regulatory targets of Odd-skipped were successfully predicted using this information, demonstrating that the data produced by the bacterial one-hybrid system are relevant to in vivo function. ..
  2. Brodsky M, Weinert B, Tsang G, Rong Y, McGinnis N, Golic K, et al. Drosophila melanogaster MNK/Chk2 and p53 regulate multiple DNA repair and apoptotic pathways following DNA damage. Mol Cell Biol. 2004;24:1219-31 pubmed
    ..Our results indicate that MNK/Chk2-dependent modification of Drosophila p53 activates a global transcriptional response to DNA damage that induces error-prone DNA repair as well as intrinsic and extrinsic apoptosis pathways. ..

    ..Moreover, Cry-dependent magnetosensitivity does not require a functioning circadian clock. Our work provides, to our knowledge, the first genetic evidence for a Cry-based magnetosensitive system in any animal. ..
  4. Fan Y, Wang S, Hernandez J, Yenigun V, Hertlein G, Fogarty C, et al. Genetic models of apoptosis-induced proliferation decipher activation of JNK and identify a requirement of EGFR signaling for tissue regenerative responses in Drosophila. PLoS Genet. 2014;10:e1004131 pubmed publisher

  5. Matranga C, Tomari Y, Shin C, Bartel D, Zamore P. Passenger-strand cleavage facilitates assembly of siRNA into Ago2-containing RNAi enzyme complexes. Cell. 2005;123:607-20 pubmed
    ..For siRNAs, virtually all RISC is assembled through this cleavage-assisted mechanism. In contrast, passenger-strand cleavage is not important for the incorporation of miRNAs that derive from mismatched duplexes. ..
  6. Dubruille R, Murad A, Rosbash M, Emery P. A constant light-genetic screen identifies KISMET as a regulator of circadian photoresponses. PLoS Genet. 2009;5:e1000787 pubmed publisher
    ..We therefore conclude that KIS is a key transcriptional regulator of genes that function in the CRY signaling cascade, and thus it plays an important role in the synchronization of circadian rhythms with the dayrationight cycle. ..
