Накратко на български

Моделирането на рака при червеите Caenorhabditis elegans позволява проучване на конкретни гени и тяхната устойчивост към химиотерапия. Това помага за по-доброто разбиране на механизмите на заболяването чрез използването на моделни организми.

Modelling cancer in Caenorhabditis elegans

I am doing this report about my research activities for 14 months (from October 2007 to February 2009) at Vall d'Hebron Hospital. As the REA know, since February first 2009 I have a junior position at Bellvitge Institute of Biomedical Research (IDIBELL). This junior position is for six years and definitively it is an essential step towards my reintegration as researcher. Regarding to these first 16 months of my reintegration period, my first goal was to set up a new laboratory specialized in the model organisms Caenorhabditis elegans in the hospital. Despite two Nobel prizes in Medicine and Physiology given to researchers working in C. elegans, this model organism is not well implemented in the Spanish Scientific System and still is largely unknown in biomedical departments. To contribute to fill this gap I have been training students and I gave several talks that resulted in scientific collaborations. Although I left Vall d'Hebrón Hospital, I am glad that there is a C. elegans laboratory still functional over there. I trained David Aristizabal (PhD student from Simo Schwartz Lab) in basic C. elegans techniques and he is now developing a fascinating research project in C. elegans related with resistance to cancer chemotherapy of certain checkpoint genes. The main student in my new lab was Laura Fontrodona. Laura was graduated in Biology in Barcelona (UAB) and she joined the lab working without any salary. I used some of the money for personal to pay her a small amount of money while she was applying for fellowships. Fortunately, Laura got her own fellowship from the Catalan Government (AGAUR) few months ago. In order to increase the number of people working in the lab, I followed the same strategy (pay while applying for a fellowship) with Monica Ferrer, a PhD with a competitive CV. Unfortunately, this strategy did not work this time. Monica did not get her fellowship and she finally left the lab. However, she did an outstanding job and we are using molecular constructs that she made to create transgenic animals. Despite the inconvenience of sep up a new lab from nothing, we manage to produce scientific results that have been showed in international meeting. I was one of the organizers of the last Spanish Worm Meeting (SWM) (in English with presence of researches of different countries) that was hold in Barcelona. In that meeting, Laura and me gave oral presentations showing our results. Moreover, we presented the following two posters in the Worm International Worm meeting , hold in Los Angeles (USA) in June 2009: rsr-2, a gene with homology to the human splicing factor SRm300, is a novel component of the sex-determination pathway in the Caenorhabditis elegans germ line.

Цел на проекта

Cancer is a complex disease that results from accumulation of diverse alterations in the genome. There are more than 300 genes identified as “cancer genes” although it is estimated that there are many more involved in cancer development that could be significant during tumorigenesis and putative targets for drugs therapies. Several scientific groups are performing a comprehensive sequencing of genes in cancer cells but these studies lack of functional validation. Since cancer requires the combination of several defects in the genome, an organism amenable for genetics and functional genomics studies as Caenorhabditis elegans would provide the ideal platform to identified those fatidic combinations. I plan to take advantage of C. elegans mutants and a “RNA interference” (RNAi) library to uncover functions and pathways of the following C. elegans genes: A) SWI/SNF complex subunit ZK1128.5 baf-60: The SWI/SNF complex is conserved from yeast to humans and acts in chromatin remodelling to regulate gene expression. baf-60 mutants present extra proliferation at particular lineages. B) Claspin, F25H5.5: Human Claspin acts as a DNA damage checkpoint through the activation of chk1 protein kinase. chk-1 also acts as a DNA damage checkpoint in C. elegans. I have preliminary results in C. elegans pointing to a novel role of Claspin in genome stability. C) Spliceosome (or splicing-related) components rsr-2 and lsm-2: I have recently published that rsr-2 and lsm-2 act in the RAS pathway that determine the vulval cell fate in C. elegans (Ceron et al, 2007). This observation and others suggests functional relationships between spliceosome-related genes and cancer. The discovery of functional networks for these genes will contribute to create a “Functional map for cancer genes” that will be a essential toward understanding this complex disease and, ultimately, find effective therapies.
