Broken chromosomes must be repaired if a cell is to survive; consequently cells have evolved a variety of mechanisms to repair double-strand breaks (DSBs). We have recently shown that RE directly interacts with the site of a DSB, and that in so doing it pulls HML close to the break. We have identified a number of adaptation-defective mutations where cells remain permanently arrested. Fast live simultaneous multiwavelength four-dimensional optical microscopy.

Anand RP, Tsaponina O, Greenwell PW, Lee CS, Du W, Petes TD, Haber JE. In addition to determining how this process occurs and how various mutations affect it, we are particularly interested in the phenomenon of donor preference, whereby MATa cells choose the donor on the left while MAT elects to recombine with the donor on the right, even if we replace HML by HMR; it is the position on the chromosome that dictates donor choice. Mutations arising during repair of chromosome breaks. There are many aspects of my Brandeis education for which I am thankful for; however, being able to work on my own research project at the Haber lab was by far the most significant and influential one. Mehta A, Haber JE. (2015). This is the process we have studied most intensively, but we are also interested in an alternative process known as break-induced replication (BIR), where only one end of a chromosome break locates a template sequence and assembles a complete replication fork and can copy sequences to the end of a chromosome, producing a nonreciprocal translocation. In 2004, we identified mutations in the EGFR gene in lung cancers which confer dramatic sensitivity to drugs that specifically inhibit that pathway. The Mancias Lab visits Brandeis University for a day long symposium on Autophagy hosted by Dr. Jim Haber at Brandeis University. Research in the Haber lab was supported by US National Institutes of Health grants GM61766, GM20056 and GM76020. J.E. Here a DSB at the MAT locus is created by a site specific HO endonuclease, which we can induce synchronously in a large population of cells. The registration fee is $10. The Postdoc Summer Seminar Series gives Brandeis Postdocs an opportunity to present their work to the Brandeis community. We are interested in understanding at the molecular level how recombination occurs and what roles are played by the many proteins involved in DNA recombination, repair and replication. Author information. The two donor loci are maintained in a chromatin configuration that prevents them from being transcribed or being cleaved by the HO endonuclease that cuts the same sequence at MAT to initiate switching. As a child he was a control in the original Salk polio vaccine trials in New York, an early experience that left him interested in how clinical trials could be more efficiently conducted.. He received his A.B. We also study the ways that a cell "knows" that there is DNA damage and how it then arrests cell growth until that damage is repaired.

But we do not yet understand how many other adaptation mutants that we have found fit into this scheme. Using synchronized cells undergoing recombination that is initiated at a specific site on a chromosome by an inducible endonuclease, we use physical monitoring techniques (Southern blots, PCR analysis) to follow the sequence of molecular events that occur in real time. Recently we used a modification of this system to study the mutation rate associated with DSB repair.

Chromatin assembly factors Asf1 and CAF-1 have overlapping roles in deactivating the DNA damage checkpoint when DNA repair is complete. David Housman was born on July 20, 1946.

In addition to repair of a double-strand chromosomal break by homologous recombination mechanisms, we have also demonstrated that yeast--like mammalian cells--also employ several nonhomologous repair pathways. We are also interested in gene targeting methods and in figuring out why these types of gene replacement and modification are quite inefficient, even in yeast. We have been studying the phenomenon of adaptation, where cells that have an unrepaired (and unrepairable) DSB will eventually escape from the G2/M DNA damage arrest checkpoint and resume growth, despite the continued presence of the broken chromosome.
