Here we explored the potential role of CDH13 in the inhibitory modulation of brain activity by investigating synaptic function of GABAergic interneurons. Cellular and subcellular distribution of CDH13 was analyzed in the murine hippocampus and a mouse model with a targeted inactivation of Cdh13 was generated to evaluate how CDH13 modulates synaptic activity of hippocampal interneurons and behavioral domains related to psychopathologic (endo) phenotypes. We show that CDH13 expression in the cornu ammonis (CA) region of the hippocampus is confined to distinct classes of interneurons. Specifically, CDH13 is expressed by numerous parvalbumin and somatostatin-expressing interneurons located in the stratum oriens, where it localizes to both the soma and the presynaptic compartment. Cdh13\(^{-/-}\) mice show an increase in basal inhibitory, but not excitatory, synaptic transmission in CA1 pyramidal neurons. Associated with these alterations in hippocampal function, Cdh13\(^{-/-}\) mice display deficits in learning and memory. Taken together, our results indicate that CDH13 is a negative regulator of inhibitory synapses in the hippocampus, and provide insights into how CDH13 dysfunction may contribute to the excitatory/inhibitory imbalance observed in neurodevelopmental disorders, such as ADHD and autism.}, language = {en} } @article{BlancoKuchenbaeckerCuadrasetal.2015, author = {Blanco, Ignacio and Kuchenbaecker, Karoline and Cuadras, Daniel and Wang, Xianshu and Barrowdale, Daniel and Ruiz de Garibay, Gorka and Librado, Pablo and Sanchez-Gracia, Alejandro and Rozas, Julio and Bonifaci, N{\´u}ria and McGuffog, Lesley and Pankratz, Vernon S. and Islam, Abul and Mateo, Francesca and Berenguer, Antoni and Petit, Anna and Catal{\`a}, Isabel and Brunet, Joan and Feliubadal{\´o}, Lidia and Tornero, Eva and Ben{\´i}tez, Javier and Osorio, Ana and Ram{\´o}n y Cajal, Teresa and Nevanlinna, Heli and Aittom{\"a}ki, Kristina and Arun, Banu K. and Toland, Amanda E. and Karlan, Beth Y. and Walsh, Christine and Lester, Jenny and Greene, Mark H. and Mai, Phuong L. and Nussbaum, Robert L. and Andrulis, Irene L. and Domchek, Susan M. and Nathanson, Katherine L. and Rebbeck, Timothy R. and Barkardottir, Rosa B. and Jakubowska, Anna and Lubinski, Jan and Durda, Katarzyna and Jaworska-Bieniek, Katarzyna and Claes, Kathleen and Van Maerken, Tom and D{\´i}ez, Orland and Hansen, Thomas V. and J{\o}nson, Lars and Gerdes, Anne-Marie and Ejlertsen, Bent and De la Hoya, Miguel and Cald{\´e}s, Trinidad and Dunning, Alison M. and Oliver, Clare and Fineberg, Elena and Cook, Margaret and Peock, Susan and McCann, Emma and Murray, Alex and Jacobs, Chris and Pichert, Gabriella and Lalloo, Fiona and Chu, Carol and Dorkins, Huw and Paterson, Joan and Ong, Kai-Ren and Teixeira, Manuel R. and Hogervorst, Frans B.

Following on these observations, we further assessed the link between the AURKA-HMMR-TPX2-TUBG1 functional module and risk of breast cancer in BRCA1 or BRCA2 mutation carriers. Forty-one single nucleotide polymorphisms (SNPs) were genotyped in 15,252 BRCA1 and 8,211 BRCA2 mutation carriers and subsequently analyzed using a retrospective likelihood approach. The association of HMMR rs299290 with breast cancer risk in BRCA1 mutation carriers was confirmed: per-allele hazard ratio (HR) = 1.10, 95\% confidence interval (CI) 1.04 - 1.15, p = 1.9 x 10\(^{-4}\) (false discovery rate (FDR)-adjusted p = 0.043). Variation in CSTF1, located next to AURKA, was also found to be associated with breast cancer risk in BRCA2 mutation carriers: rs2426618 per-allele HR = 1.10, 95\% CI 1.03 - 1.16, p = 0.005 (FDR-adjusted p = 0.045). Assessment of pairwise interactions provided suggestions (FDR-adjusted p\(_{interaction}\) values > 0.05) for deviations from the multiplicative model for rs299290 and CSTF1 rs6064391, and rs299290 and TUBG1 rs11649877 in both BRCA1 and BRCA2 mutation carriers. Following these suggestions, the expression of HMMR and AURKA or TUBG1 in sporadic breast tumors was found to potentially interact, influencing patients' survival. Together, the results of this study support the hypothesis of a causative link between altered function of AURKA-HMMR-TPX2-TUBG1 and breast carcinogenesis in BRCA1/2 mutation carriers.}, language = {en} }
