The Genetic Architecture of Major Depressive Disorder in Han Chinese Women.

Importance: Despite the moderate, well-demonstrated heritability of major depressive disorder (MDD), there has been limited success in identifying replicable genetic risk loci, suggesting a complex genetic architecture. Research is needed to quantify the relative contribution of classes of genetic variation across the genome to inform future genetic studies of MDD.

Objectives: To apply aggregate genetic risk methods to clarify the genetic architecture of MDD by estimating and partitioning heritability by chromosome, minor allele frequency, and functional annotations and to test for enrichment of rare deleterious variants.

[Correlations between clusters of protein-DNA binding sites and the binding experimental data allow to predict a structure of regulatory modules].

Here we analyzed an option to predict the structure of cis-regulatory modules that consist of binding sites of different proteins (heterogeneous cis-regulatory modules) using mutual positional correlations between protein-DNA binding experimental data and computationally identified clusters of binding sites for each of the proteins.

CORECLUST: identification of the conserved CRM grammar together with prediction of gene regulation.

Identification of transcriptional regulatory regions and tracing their internal organization are important for understanding the eukaryotic cell machinery. Cis-regulatory modules (CRMs) of higher eukaryotes are believed to possess a regulatory 'grammar', or preferred arrangement of binding sites, that is crucial for proper regulation and thus tends to be evolutionarily conserved. Here, we present a method CORECLUST (COnservative REgulatory CLUster STructure) that predicts CRMs based on a set of positional weight matrices.

Analysis of DNA-protein interactions in complexes of transcription factor NF-kappaB with DNA.

We have applied bioinformatic analysis of X-ray 3D structures of complexes of transcription factor NF-kappaB with DNAs. We determined the number of possible Van der Waals contacts and hydrogen bonds between amino acid residues and nucleotides. Conservative contacts in the NF-kappaB dimer-DNA complex composed of p50 and/or p65 NF-kappaB subunit and DNA sequences like 5 -GGGAMWTTCC-3 were revealed.

[A discrepancy between the experimental and theoretical data on energy migration from B800 to B850 in LH-2 antennary complexes in purple bacteria].

A discrepancy between the times of excitation transfer from B800 to B850 bacteriochlorophyll fractions in LH-2 complexes of purple bacteria was revealed. The experimental value (0.7-0.
