    Description: In Saccharomyces cerevisiae, more than 80% of the approximately 6200 predicted genes are nonessential, implying that the genome is buffered from the phenotypic consequences of genetic perturbation. To evaluate function, we developed a method for systematic construction of double mutants, termed synthetic genetic array (SGA) analysis, in which a query mutation is crossed to an array of approximately 4700 deletion mutants. Inviable double-mutant meiotic progeny identify functional relationships between genes. SGA analysis of genes with roles in cytoskeletal organization (BNI1, ARP2, ARC40, BIM1), DNA synthesis and repair (SGS1, RAD27), or uncharacterized functions (BBC1, NBP2) generated a network of 291 interactions among 204 genes. Systematic application of this approach should produce a global map of gene function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tong, A H -- Evangelista, M -- Parsons, A B -- Xu, H -- Bader, G D -- Page, N -- Robinson, M -- Raghibizadeh, S -- Hogue, C W -- Bussey, H -- Andrews, B -- Tyers, M -- Boone, C -- New York, N.Y. -- Science. 2001 Dec 14;294(5550):2364-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Banting and Best Department of Medical Research, University of Toronto, Toronto ON, Canada M5G 1L6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11743205" target="_blank"〉PubMed〈/a〉

    Description: A genome-scale genetic interaction map was constructed by examining 5.4 million gene-gene pairs for synthetic genetic interactions, generating quantitative genetic interaction profiles for approximately 75% of all genes in the budding yeast, Saccharomyces cerevisiae. A network based on genetic interaction profiles reveals a functional map of the cell in which genes of similar biological processes cluster together in coherent subsets, and highly correlated profiles delineate specific pathways to define gene function. The global network identifies functional cross-connections between all bioprocesses, mapping a cellular wiring diagram of pleiotropy. Genetic interaction degree correlated with a number of different gene attributes, which may be informative about genetic network hubs in other organisms. We also demonstrate that extensive and unbiased mapping of the genetic landscape provides a key for interpretation of chemical-genetic interactions and drug target identification.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Costanzo, Michael -- Baryshnikova, Anastasia -- Bellay, Jeremy -- Kim, Yungil -- Spear, Eric D -- Sevier, Carolyn S -- Ding, Huiming -- Koh, Judice L Y -- Toufighi, Kiana -- Mostafavi, Sara -- Prinz, Jeany -- St Onge, Robert P -- VanderSluis, Benjamin -- Makhnevych, Taras -- Vizeacoumar, Franco J -- Alizadeh, Solmaz -- Bahr, Sondra -- Brost, Renee L -- Chen, Yiqun -- Cokol, Murat -- Deshpande, Raamesh -- Li, Zhijian -- Lin, Zhen-Yuan -- Liang, Wendy -- Marback, Michaela -- Paw, Jadine -- San Luis, Bryan-Joseph -- Shuteriqi, Ermira -- Tong, Amy Hin Yan -- van Dyk, Nydia -- Wallace, Iain M -- Whitney, Joseph A -- Weirauch, Matthew T -- Zhong, Guoqing -- Zhu, Hongwei -- Houry, Walid A -- Brudno, Michael -- Ragibizadeh, Sasan -- Papp, Balazs -- Pal, Csaba -- Roth, Frederick P -- Giaever, Guri -- Nislow, Corey -- Troyanskaya, Olga G -- Bussey, Howard -- Bader, Gary D -- Gingras, Anne-Claude -- Morris, Quaid D -- Kim, Philip M -- Kaiser, Chris A -- Myers, Chad L -- Andrews, Brenda J -- Boone, Charles -- 084314/Wellcome Trust/United Kingdom -- GSP-41567/Canadian Institutes of Health Research/Canada -- R01 HG003224/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 22;327(5964):425-31. doi: 10.1126/science.1180823.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Banting and Best Department of Medical Research, Terrence Donnelly Centre for Cellular and Biomolecular Research, University of Toronto, Toronto, Ontario M5S 3E1, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20093466" target="_blank"〉PubMed〈/a〉

    Notes: Summary Target cells for 1,25-dihydroxyvitamin D3 were demonstrated in the adrenal medulla by frozen-section autoradiography. The appearance of these target cells was age-dependent in neonatal mice. Immunocytochemical staining for phenylethanolamine-N-methyltransferase revealed that both epinephrine and non-epinephrine cells concentrate 1,25-dihydroxyvitamin D3 in their nuclei. In contrast, immunocytochemical staining for “vitamin D-dependent calcium-binding protein” (D-CaBP) demonstrated that D-CaBP immunoreactivity is localized in only a small percentage of adrenomedullary cells, in mice and rats. Comparison of PNMT and D-CaBP immunoreactivities in sequential sections showed that epinephrine-producing cells do not contain D-CaBP. These results indicate that adrenal medullary cells have receptors for 1,25-dihydroxyvitamin D3 and that 1,25-dihydroxyvitamin D3 may directly affect certain functions of these endocrine cells.

    Notes: Summary The human fetal sympathetic ganglia were studied using the indirect peroxidase-antiperoxidase PAP method for immunocytochemical demonstration of three catecholamine-synthesizing enzymes, tyrosine hydroxylase (TH), dopamine-β-hydroxylase (DBH) and phenylethanolamine-N-methyltransferase (PNMT) as well as the neuropeptides leucine (Leu5)-enkephalin and substance P. The neuroblasts of the ganglia showed intense peroxidase immunoreactivity for TH, moderate reaction to DBH, and no reaction to PNMT. The small intensely fluorescent (SIF) cells situated along the blood vessels also showed positive labelling for only two enzymes, TH and DBH. The immunocytochemical localization of these enzymes suggests that both neuroblasts and SIF cells synthesize noradrenalin. Neither the neuroblasts nor SIF cells showed a reaction to substance P, and only the SIF cells contained enkephalin-like immunoreactivity. The role of enkephalin in the noradrenalin-containing SIF cells is unknown, but may be related to neuromodulation of ganglionic transmission.
