Abstract
Modern drug discovery relies on combinatorial screening campaigns to find drug molecules targeting specific disease-associated proteins. The success of such campaigns often relies on functional and structural information of the selected therapeutic target, only achievable once its purification is mastered. With the aim of bypassing the protein purification process to gain insights on the druggability, ligand binding, and/or characterization of protein-protein interactions, herein, we describe the Extract2Chip method. This approach builds on the immobilization of site-specific biotinylated proteins of interest, directly from cellular extracts, on avidin-coated sensor chips to allow for the characterization of molecular interactions via surface plasmon resonance (SPR). The developed method was initially validated using Cyclophilin D (CypD) and subsequently applied to other drug discovery projects in which the targets of interest were difficult to express, purify, and crystallize. Extract2Chip was successfully applied to the characterization of Yes-associated protein (YAP): Transcriptional enhancer factor TEF (TEAD1) protein-protein interaction inhibitors, in the validation of a ternary complex assembly composed of Dyskerin pseudouridine synthase 1 (DKC1) and RuvBL1/RuvBL2, and in the establishment of a fast-screening platform to select the most suitable NUAK family SNF1-like kinase 2 (NUAK2) surrogate for binding and structural studies. The described method paves the way for a potential revival of the many drug discovery campaigns that have failed to deliver due to the lack of suitable and sufficient protein supply.

Abstract
Recent breakthroughs with synthetic budding yeast chromosomes expedite the creation of synthetic mammalian chromosomes and genomes. Mammals, unlike budding yeast, depend on the histone H3 variant, CENP-A, to epigenetically specify the location of the centromere-the locus essential for chromosome segregation. Prior human artificial chromosomes (HACs) required large arrays of centromeric α-satellite repeats harboring binding sites for the DNA sequence-specific binding protein, CENP-B. We report the development of a type of HAC that functions independently of these constraints. Formed by an initial CENP-A nucleosome seeding strategy, a construct lacking repetitive centromeric DNA formed several self-sufficient HACs that showed no uptake of genomic DNA. In contrast to traditional α-satellite HAC formation, the non-repetitive construct can form functional HACs without CENP-B or initial CENP-A nucleosome seeding, revealing distinct paths to centromere formation for different DNA sequence types. Our developments streamline the construction and characterization of HACs to facilitate mammalian synthetic genome efforts.

Abstract
In recent years, various synthetic approaches have been developed to address the question of what directs centromere establishment and maintenance. In this chapter, we will discuss how approaches aimed at constructing synthetic centromeres have co-evolved with and contributed to shape the theory describing the determinants of centromere identity. We will first review lessons learned from artificial chromosomes created from "naked" centromeric sequences to investigate the role of the underlying DNA for centromere formation. We will then discuss how several studies, which applied removal of endogenous centromeres or over-expression of the centromere-specific histone CENP-A, helped to investigate the contribution of chromatin context to centromere establishment. Finally, we will examine various biosynthetic approaches taking advantage of targeting specific proteins to ectopic sites in the genome to dissect the role of many centromere-associated proteins and chromatin modifiers for centromere inheritance and function. Together, these studies showed that chromatin context matters, particularly proximity to heterochromatin or repetitive DNA sequences. Moreover, despite the important contribution of centromeric DNA, the centromere-specific histone H3-variant CENP-A emerges as a key epigenetic mark to establish and maintain functional centromeres on artificial chromosomes or at ectopic sites of the genome.

Abstract
New roles for the N-terminal histone tail and folded core of CENP-A are revealed by monitoring early steps in centromere establishment. The centromere—defined by the presence of nucleosomes containing the histone H3 variant, CENP-A—is the chromosomal locus required for the accurate segregation of chromosomes during cell division. Although the sequence determinants of human CENP-A required to maintain a centromere were reported, those that are required for early steps in establishing a new centromere are unknown. In this paper, we used gain-of-function histone H3 chimeras containing various regions unique to CENP-A to investigate early events in centromere establishment. We targeted histone H3 chimeras to chromosomally integrated Lac operator sequences by fusing each of the chimeras to the Lac repressor. Using this approach, we found surprising contributions from a small portion of the N-terminal tail and the CENP-A targeting domain in the initial recruitment of two essential constitutive centromere proteins, CENP-C and CENP-T. Our results indicate that the regions of CENP-A required for early events in centromere establishment differ from those that are required for maintaining centromere identity.

Abstract
REASONS FOR PERFORMING STUDY MicroRNAs (miRNA) are small endogenous noncoding interfering RNA molecules (18-25 nucleotides) regarded as major regulators in eukaryotic gene expression. They play a role in developmental timing, cellular differentiation, signalling and apoptosis pathways. Because of the central function of miRNAs in the proliferation and differentiation of the myoblasts demonstrated in mouse and man, it is assumed that they could be present in equine muscles and their expression profile may be related to the muscle status. OBJECTIVE To identify miRNA candidates in the muscles of control and affected horses suffering from polysaccharide storage myopathy (PSSM) and recurrent exertional rhabdomyolysis (RER). METHODS Muscle biopsies were collected in the gluteus medius of horses allocated into 4 groups: French Trotters (3 control-TF vs. 3 RER-TF) and Norman Cob (5 control-Cob vs. 9 PSSM-Cob). Blood samples were collected for miRNA analysis. Total RNA were extracted and real time quantitative RT-QPCR analysis were conducted using 10 miRNA assays (mir-1-23-30-133-181-188-195-206-339-375). RESULTS All the miRNA candidates were significantly detected in the muscles and some in blood samples. Variance analysis revealed highly significant (P < 0.0001) effects of the miRNA type, breed and pathology on the miRNA expression. A specific miRNA profile was related to each myopathy: a higher expression of mir-1, 133, 23a, 30b, 195 and 339 in RER-TF vs. control-TF (P < 0.05); a higher expression of mir-195 in PSSM-Cob vs. control-Cob (P < 0.05). The miRNA profile was different between breeds for mir-181, 188 and 206 (P < 0.05). The mir-1, 133, 181, 195 and 206 were detected in blood of control-Cob and PSSM-Cob horses. CONCLUSIONS This first study about muscular miRNA profile in equine myopathies indicated that it is possible to discriminate pathological from control horses according to their miRNA profile. The RER miRNA profile was more specific and contrasted than the PSSM profile.
