[{"abstract":[{"text":"BACKGROUND: Gene duplications have a major role in the evolution of new biological functions. Theoretical studies often assume that a duplication per se is selectively neutral and that, following a duplication, one of the gene copies is freed from purifying (stabilizing) selection, which creates the potential for evolution of a new function. RESULTS: In search of systematic evidence of accelerated evolution after duplication, we used data from 26 bacterial, six archaeal, and seven eukaryotic genomes to compare the mode and strength of selection acting on recently duplicated genes (paralogs) and on similarly diverged, unduplicated orthologous genes in different species. We find that the ratio of nonsynonymous to synonymous substitutions (Kn/Ks) in most paralogous pairs is <<1 and that paralogs typically evolve at similar rates, without significant asymmetry, indicating that both paralogs produced by a duplication are subject to purifying selection. This selection is, however, substantially weaker than the purifying selection affecting unduplicated orthologs that have diverged to the same extent as the analyzed paralogs. Most of the recently duplicated genes appear to be involved in various forms of environmental response; in particular, many of them encode membrane and secreted proteins. CONCLUSIONS: The results of this analysis indicate that recently duplicated paralogs evolve faster than orthologs with the same level of divergence and similar functions, but apparently do not experience a phase of neutral evolution. We hypothesize that gene duplications that persist in an evolving lineage are beneficial from the time of their origin, due primarily to a protein dosage effect in response to variable environmental conditions; duplications are likely to give rise to new functions at a later phase of their evolution once a higher level of divergence is reached.","lang":"eng"}],"publication_identifier":{"issn":["1465-6906"]},"publication":"Genome Biology","date_created":"2018-12-11T11:48:57Z","date_updated":"2023-07-26T11:48:27Z","type":"journal_article","article_type":"original","user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","title":"Selection in the evolution of gene duplications ","oa":1,"main_file_link":[{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC65685/","open_access":"1"}],"status":"public","citation":{"ieee":"F.

On average, ≈10% of deviations of a nonhuman protein from its human ortholog are compensated pathogenic deviations (CPDs), i.e., are caused by an amino acid substitution that, at this site, would be pathogenic to humans. Normal functioning of a CPD-containing protein must be caused by other, compensatory deviations of the nonhuman species from humans. Together, a CPD and the corresponding compensatory deviation form a Dobzhansky-Muller incompatibility that can be visualized as the corner on a fitness ridge. Thus, proteins evolve along fitness ridges which contain only ≈10 steps between sucessive corners. The fraction of CPDs among all deviations of a protein from its human ortholog does not increase with the evolutionary distance between the proteins, indicating that subtitutions that carry evolving proteins around these corners occur in rapid succession, driven by positive selection. Data on fitness of interspecies hybrids suggest that the compensatory change that makes a CPD fit usually occurs within the same protein. Data on protein structures and on cooccurrence of amino acids at different sites of multiple orthologous proteins often make it possible to provisionally identify the substitution that compensates a partiCUlar CPD."}],"publication":"PNAS","date_created":"2018-12-11T11:49:01Z","publication_identifier":{"issn":["0027-8424"]},"oa":1,"article_type":"original","user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","title":"Dobzhansky-Muller incompatibilities in protein evolution","scopus_import":"1","main_file_link":[{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC137512/","open_access":"1"}],"status":"public","citation":{"ama":"Kondrashov A, Sunyaev S, Kondrashov F.

Region 3 is described by a one-dimensional functional, which is identical to the so-called Hyper-Strong functional introduced by Lieb, Solovej and Yngvason for atoms with fermionic electrons in the region B≫Z3 ; i.e., for very strong magnetic fields the ground state properties of atoms are independent of statistics. For Region 2 we introduce a general magnetic Hartree functional, which is studied in detail. It is shown that in the special case of an atom it can be restricted to the subspace of zero angular momentum parallel to the magnetic field, which simplifies the theory considerably. The functional reproduces the energy and the one-particle reduced density matrix for the full N-particle ground state to leading order in N, and it implies the description of the other regions as limiting cases.","lang":"eng"}],"oa":1,"user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","title":"Atoms with bosonic "electrons" in strong magnetic fields","article_type":"original","scopus_import":"1","citation":{"ista":"Baumgartner B, Seiringer R. 2001.

In the limit when the nuclear charge Z tends to ∞ with the magnetic field B satisfying B ≫ Z4/3 all the electrons are confined to the lowest Landau band. We consider here an energy functional, whose variable is a sequence of one-dimensional density matrices corresponding to different angular momentum functions in the lowest Landau band. We study this functional in detail and derive various interesting properties, which are compared with the density matrix (DM) theory introduced by Lieb, Solovej and Yngvason. In contrast to the DM theory the variable perpendicular to the field is replaced by the discrete angular momentum quantum numbers. Hence we call the new functional a discrete density matrix (DDM) functional. We relate this DDM theory to the lowest Landau band quantum mechanics and show that it reproduces correctly the ground state energy apart from errors due to the indirect part of the Coulomb interaction energy.","lang":"eng"}],"date_updated":"2023-05-30T06:54:54Z","type":"journal_article","title":"A discrete density matrix theory for atoms in strong magnetic fields","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_type":"original","oa":1,"citation":{"ama":"Hainzl C, Seiringer R.

After the serendipitous discovery of a sensory stimulus-evoked epileptic phenotype, we tested two convulsant drugs, pentylenetetrazole (PTZ) and bicuculline. In animals aged 12 weeks and older, subthreshold doses of these drugs induced seizures in mGluR7 -/-, but not in mGluR7 +/-, mice. PTZ-induced seizures were inhibited by three standard anticonvulsant drugs, but not by the group III selective mGluR agonist (R,S)-4-phosphonophenylglycine (PPG). Consistent with the lack of signs of epileptic activity in the absence of specific stimuli, mGluR7 -/- mice showed no major changes in synaptic properties in two slice preparations. However, slightly increased excitability was evident in hippocampal slices. In addition, there was slower recovery from frequency facilitation in cortical slices, suggesting a role for mGluR7 as a frequency-dependent regulator in presynaptic terminals. Our findings suggest that mGluR7 receptors have a unique role in regulating neuronal excitability and that these receptors may be a novel target for the development of anticonvulsant drugs.","lang":"eng"}],"oa":1,"user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","title":"Increased seizure susceptibility in mice lacking metabotropic glutamate receptor 7","article_type":"original"},{"volume":13,"publist_id":"4158","intvolume":" 13","author":[{"first_name":"László","orcid":"0000-0001-5366-9603","last_name":"Erdös","id":"4DBD5372-F248-11E8-B48F-1D18A9856A87","full_name":"Erdös, László"},{"last_name":"Solovej","full_name":"Solovej, Jan","first_name":"Jan"}],"issue":"10","_id":"2734","extern":"1","external_id":{"arxiv":["math-ph/0001036"]},"year":"2001","publisher":"World Scientific Publishing","page":"1247 - 1280","article_processing_charge":"No","date_published":"2001-10-01T00:00:00Z","type":"journal_article","date_updated":"2023-05-16T12:24:25Z","publication":"Reviews in Mathematical Physics","date_created":"2018-12-11T11:59:19Z","publication_identifier":{"issn":["0129-055X"]},"abstract":[{"lang":"eng","text":"In this paper we describe an intrinsically geometric way of producing magnetic fields on S3 and R3 for which the corresponding Dirac operators have a non-trivial kernel.

We have found that two mutants of Arabidopsis - doc1, which displays altered expression of light-regulated genes, and tir3, known for its reduced auxin transport - have similar defects and define mutations in a single gene that we have renamed BIG. BIG is very similar to the Drosophila gene Calossin/Pushover, a member of a gene family also present in Caenorhabditis elegans and human genomes. The protein encoded by BIG is extraordinary in size, 560 kD, and contains several putative Zn-finger domains. Expression-profiling experiments indicate that altered expression of multiple light-regulated genes in doc1 mutants can be suppressed by elevated levels of auxin caused by overexpression of an auxin biosynthetic gene, suggesting that normal auxin distribution is required to maintain low-level expression of these genes in the dark. Double mutants of tir3 with the auxin mutants pin1, pid, and axr1 display severe defects in auxin-dependent growth of the inflorescence. Chemical inhibitors of auxin transport change the intracellular localization of the auxin efflux carrier PIN1 in doc1/tir3 mutants, supporting the idea that BIG is required for normal auxin efflux."}],"type":"journal_article","date_updated":"2023-05-16T11:59:47Z","title":"BIG: A calossin-like protein required for polar auxin transport in Arabidopsis","user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","article_type":"original","oa":1,"citation":{"apa":"Gil, P., Dewey, E., Friml, J., Zhao, Y., Snowden, K., Putterill, J., … Chory, J.

Plants use specialized carrier proteins to transport the auxin indole-3-acetic acid (IAA) to target tissues. To date, efflux carrier-mediated polar auxin transport has been assumed to represent the sole mode of long distance IAA movement. Localization of the auxin permease AUX1 in the Arabidopsis root apex has revealed a novel phloem-based IAA transport pathway. AUX1, asymmetrically localized to the plasma membrane of root protophloem cells, is proposed to promote the acropetal, post-phloem movement of auxin to the root apex. MS analysis shows that IAA accumulation in aux1 mutant root apices is impaired, consistent with an AUX1 phloem unloading function. AUX1 localization to columella and lateral root cap tissues of the Arabidopsis root apex reveals that the auxin permease regulates a second IAA transport pathway. Expression studies using an auxin-regulated reporter suggest that AUX1 is necessary for root gravitropism by facilitating basipetal auxin transport to distal elongation zone tissues.","lang":"eng"}],"publication_identifier":{"issn":["Genes and Development"]},"publication":"Genes and Development","date_created":"2018-12-11T12:00:41Z","date_updated":"2023-05-16T11:37:53Z","type":"journal_article","month":"10","doi":"10.1101/gad.210501","day":"15","publication_status":"published","quality_controlled":"1","language":[{"iso":"eng"}],"oa_version":"Published Version","main_file_link":[{"open_access":"1","url":"ncbi.nlm.nih.gov/pmc/articles/PMC312818/"}],"status":"public","citation":{"ista":"Swarup R, Friml J, Marchant A, Ljung K, Sandberg G, Palme K, Bennett M. 2001.

Microwave anisotropy experiments, such as MAP or Planck, will set constraints on the ionization history of the intergalactic medium due to these sources. In the infrared, the Next Generation Space Telescope (NGST) will be able to directly detect sub-galactic objects at redshifts z>10. In the optical, data from the Hubble Deep Field already places a constraint on the abundance of high-redshift quasars. However, the epoch of the first quasars might be first probed in X-ray bands, by instruments such as the Chandra X-ray Observatory (CXO) and the X-ray Multi-mirror Mission (XMM). In a 500 Ksec integration, CXO reaches a sensitivity of 2x10-16 erg/s cm^2. Based on simple hierarchical CDM models, we find that at this flux threshold approx. 100 quasars might be detectable from redshifts z>5, and approx. 1 quasar at z=10, in each 17x17 arcmin field. Measurement of the power spectrum of the unresolved soft X-ray background will further constrain models of faint, high-redshift quasars."}],"publication":"AIP Conference Proceedings","date_created":"2025-01-03T12:29:34Z","publication_identifier":{"issn":["0094-243X"]},"conference":{"location":"Bologna, Italy","end_date":"1999-09-10","name":"X-RAY ASTRONOMY: Stellar Endpoints,AGN, and the Diffuse X-ray Background","start_date":"1999-09-06"},"oa":1,"OA_place":"repository","title":"Probing the cosmic dark age in X-rays","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","OA_type":"green","scopus_import":"1","status":"public","main_file_link":[{"url":"https://arxiv.org/abs/astro-ph/0001271","open_access":"1"}],"citation":{"apa":"Haiman, Z.

Here we assess the power of future surveys to determine cosmological parameters. We quantify the statistical differences among cosmologies, including the effects of the cosmic equation of state parameter w, in mock cluster catalogs simulating a 12 deg^2 Sunyaev-Zel’dovich Effect (SZE) survey and a deep 10^4 deg^2 X-ray survey. The constraints from clusters are complementary to those from studies of high-redshift Supernovae (SNe), CMB anisotropies, or counts of high-redshift galaxies. Our results indicate that a statistical uncertainty of a few percent on both Ωm\r\n and w can be reached when cluster surveys are used in combination with any of these other datasets."}],"type":"journal_article","date_updated":"2025-01-07T14:08:38Z","publication_status":"published","day":"15","doi":"10.1063/1.1419569","month":"10","quality_controlled":"1","oa_version":"Preprint","language":[{"iso":"eng"}],"arxiv":1,"citation":{"ieee":"Z.
