    Description: Article Identifying therapeutic targets in rare cancers is challenging due to the lack of relevant pre-clinical models. Here, the authors generate a cancer cell line from a paediatric patient with a rare undifferentiated sarcoma and through functional genomics and chemical screens identified CDK4 and XPO1 as potential therapeutic targets in this cancer.

    Description: Puberty onset is initiated by activation of neurons that secrete gonadotropin-releasing hormone (GnRH). The timing and progression of puberty may depend upon temporal coordination of two opposing central mechanisms—a restraint of GnRH secretion before puberty onset, followed by enhanced stimulation of GnRH release to complete reproductive maturation during puberty. Neuronal estrogen receptor α (ERα) has been implicated in both controls; however, the underlying neural circuits are not well understood. Here we test whether these mechanisms are mediated by neurons that express kisspeptin, a neuropeptide that modulates GnRH neurosecretion. Strikingly, conditional ablation of ERα in kisspeptin neurons results in a dramatic advancement of puberty onset in female mice. Furthermore, subsequent pubertal maturation is arrested in these animals, as they fail to acquire normal ovulatory cyclicity. We show that the temporal coordination of juvenile restraint and subsequent pubertal activation is likely mediated by ERα in two separate kisspeptin neuronal populations in the hypothalamus.

    Description: Glutamatergic neurotransmission is controlled by presynaptic metabotropic glutamate receptors (mGluRs). A subdomain in the intracellular carboxyl-terminal tail of group III mGluRs binds calmodulin and heterotrimeric guanosine triphosphate-binding protein (G protein) betagamma subunits in a mutually exclusive manner. Mutations interfering with calmodulin binding and calmodulin antagonists inhibit G protein-mediated modulation of ionic currents by mGluR 7. Calmodulin antagonists also prevent inhibition of excitatory neurotransmission via presynaptic mGluRs. These results reveal a novel mechanism of presynaptic modulation in which Ca(2+)-calmodulin is required to release G protein betagamma subunits from the C-tail of group III mGluRs in order to mediate glutamatergic autoinhibition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Connor, V -- El Far, O -- Bofill-Cardona, E -- Nanoff, C -- Freissmuth, M -- Karschin, A -- Airas, J M -- Betz, H -- Boehm, S -- New York, N.Y. -- Science. 1999 Nov 5;286(5442):1180-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurochemistry, Max Planck Institute for Brain Research, Deutschordenstrasse 46, 60528 Frankfurt, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10550060" target="_blank"〉PubMed〈/a〉

    Description: Oncogenic mutations in the serine/threonine kinase B-RAF (also known as BRAF) are found in 50-70% of malignant melanomas. Pre-clinical studies have demonstrated that the B-RAF(V600E) mutation predicts a dependency on the mitogen-activated protein kinase (MAPK) signalling cascade in melanoma-an observation that has been validated by the success of RAF and MEK inhibitors in clinical trials. However, clinical responses to targeted anticancer therapeutics are frequently confounded by de novo or acquired resistance. Identification of resistance mechanisms in a manner that elucidates alternative 'druggable' targets may inform effective long-term treatment strategies. Here we expressed approximately 600 kinase and kinase-related open reading frames (ORFs) in parallel to interrogate resistance to a selective RAF kinase inhibitor. We identified MAP3K8 (the gene encoding COT/Tpl2) as a MAPK pathway agonist that drives resistance to RAF inhibition in B-RAF(V600E) cell lines. COT activates ERK primarily through MEK-dependent mechanisms that do not require RAF signalling. Moreover, COT expression is associated with de novo resistance in B-RAF(V600E) cultured cell lines and acquired resistance in melanoma cells and tissue obtained from relapsing patients following treatment with MEK or RAF inhibitors. We further identify combinatorial MAPK pathway inhibition or targeting of COT kinase activity as possible therapeutic strategies for reducing MAPK pathway activation in this setting. Together, these results provide new insights into resistance mechanisms involving the MAPK pathway and articulate an integrative approach through which high-throughput functional screens may inform the development of novel therapeutic strategies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3058384/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3058384/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johannessen, Cory M -- Boehm, Jesse S -- Kim, So Young -- Thomas, Sapana R -- Wardwell, Leslie -- Johnson, Laura A -- Emery, Caroline M -- Stransky, Nicolas -- Cogdill, Alexandria P -- Barretina, Jordi -- Caponigro, Giordano -- Hieronymus, Haley -- Murray, Ryan R -- Salehi-Ashtiani, Kourosh -- Hill, David E -- Vidal, Marc -- Zhao, Jean J -- Yang, Xiaoping -- Alkan, Ozan -- Kim, Sungjoon -- Harris, Jennifer L -- Wilson, Christopher J -- Myer, Vic E -- Finan, Peter M -- Root, David E -- Roberts, Thomas M -- Golub, Todd -- Flaherty, Keith T -- Dummer, Reinhard -- Weber, Barbara L -- Sellers, William R -- Schlegel, Robert -- Wargo, Jennifer A -- Hahn, William C -- Garraway, Levi A -- CA134502/CA/NCI NIH HHS/ -- DP2 OD002750/OD/NIH HHS/ -- DP2 OD002750-01/OD/NIH HHS/ -- K08 CA115927/CA/NCI NIH HHS/ -- K08 CA115927-05/CA/NCI NIH HHS/ -- P50 CA093683/CA/NCI NIH HHS/ -- R01 CA134502/CA/NCI NIH HHS/ -- R33 CA128625/CA/NCI NIH HHS/ -- RC2 CA148268/CA/NCI NIH HHS/ -- England -- Nature. 2010 Dec 16;468(7326):968-72. doi: 10.1038/nature09627.

    Description: A powerful way to discover key genes with causal roles in oncogenesis is to identify genomic regions that undergo frequent alteration in human cancers. Here we present high-resolution analyses of somatic copy-number alterations (SCNAs) from 3,131 cancer specimens, belonging largely to 26 histological types. We identify 158 regions of focal SCNA that are altered at significant frequency across several cancer types, of which 122 cannot be explained by the presence of a known cancer target gene located within these regions. Several gene families are enriched among these regions of focal SCNA, including the BCL2 family of apoptosis regulators and the NF-kappaBeta pathway. We show that cancer cells containing amplifications surrounding the MCL1 and BCL2L1 anti-apoptotic genes depend on the expression of these genes for survival. Finally, we demonstrate that a large majority of SCNAs identified in individual cancer types are present in several cancer types.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2826709/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2826709/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beroukhim, Rameen -- Mermel, Craig H -- Porter, Dale -- Wei, Guo -- Raychaudhuri, Soumya -- Donovan, Jerry -- Barretina, Jordi -- Boehm, Jesse S -- Dobson, Jennifer -- Urashima, Mitsuyoshi -- Mc Henry, Kevin T -- Pinchback, Reid M -- Ligon, Azra H -- Cho, Yoon-Jae -- Haery, Leila -- Greulich, Heidi -- Reich, Michael -- Winckler, Wendy -- Lawrence, Michael S -- Weir, Barbara A -- Tanaka, Kumiko E -- Chiang, Derek Y -- Bass, Adam J -- Loo, Alice -- Hoffman, Carter -- Prensner, John -- Liefeld, Ted -- Gao, Qing -- Yecies, Derek -- Signoretti, Sabina -- Maher, Elizabeth -- Kaye, Frederic J -- Sasaki, Hidefumi -- Tepper, Joel E -- Fletcher, Jonathan A -- Tabernero, Josep -- Baselga, Jose -- Tsao, Ming-Sound -- Demichelis, Francesca -- Rubin, Mark A -- Janne, Pasi A -- Daly, Mark J -- Nucera, Carmelo -- Levine, Ross L -- Ebert, Benjamin L -- Gabriel, Stacey -- Rustgi, Anil K -- Antonescu, Cristina R -- Ladanyi, Marc -- Letai, Anthony -- Garraway, Levi A -- Loda, Massimo -- Beer, David G -- True, Lawrence D -- Okamoto, Aikou -- Pomeroy, Scott L -- Singer, Samuel -- Golub, Todd R -- Lander, Eric S -- Getz, Gad -- Sellers, William R -- Meyerson, Matthew -- K08 AR055688/AR/NIAMS NIH HHS/ -- K08 AR055688-03/AR/NIAMS NIH HHS/ -- K08 AR055688-04/AR/NIAMS NIH HHS/ -- K08 CA122833/CA/NCI NIH HHS/ -- K08 CA122833-01A1/CA/NCI NIH HHS/ -- K08 CA122833-02/CA/NCI NIH HHS/ -- K08 CA122833-03/CA/NCI NIH HHS/ -- K08 CA134931/CA/NCI NIH HHS/ -- K08CA122833/CA/NCI NIH HHS/ -- P01CA 098101/CA/NCI NIH HHS/ -- P01CA085859/CA/NCI NIH HHS/ -- P50CA90578/CA/NCI NIH HHS/ -- R01 CA109038/CA/NCI NIH HHS/ -- R01 GM074024/GM/NIGMS NIH HHS/ -- R01CA109038/CA/NCI NIH HHS/ -- R01CA109467/CA/NCI NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- U24 CA126546/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Feb 18;463(7283):899-905. doi: 10.1038/nature08822.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Program and Medical and Population Genetics Group, The Broad Institute of M.I.T. and Harvard, 7 Cambridge Center.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20164920" target="_blank"〉PubMed〈/a〉
