Novel pharmacological maps of protein lysine methyltransferases: key for target deorphanization
Epigenetic therapies are being investigated for the treatment of cancer, cognitive disorders, metabolic alterations and
autoinmune diseases. Among the diferent epigenetic target families, protein lysine methyltransferases (PKMTs), are
especially interesting because it is believed that their inhibition may be highly specifc at the functional level. Despite
its relevance, there are currently known inhibitors against only 10 out of the 50 SET-domain containing members of
the PKMT family. Accordingly, the identifcation of chemical probes for the validation of the therapeutic impact of
epigenetic modulation is key. Moreover, little is known about the mechanisms that dictate their substrate specifcity and ligand selectivity. Consequently, it is desirable to explore novel methods to characterize the pharmacological similarity of PKMTs, going beyond classical phylogenetic relationships. Such characterization would enable the
prediction of ligand of-target efects caused by lack of ligand selectivity and the repurposing of known compounds
against alternative targets. This is particularly relevant in the case of orphan targets with unreported inhibitors. Here,
we frst perform a systematic study of binding modes of cofactor and substrate bound ligands with all available SET
domain-containing PKMTs. Protein ligand interaction fngerprints were applied to identify conserved hot spots and
contact-specifc residues across subfamilies at each binding site; a relevant analysis for guiding the design of novel,
selective compounds. Then, a recently described methodology (GPCR-CoINPocket) that incorporates ligand contact
information into classical alignment-based comparisons was applied to the entire family of 50 SET-containing proteins
to devise pharmacological similarities between them. The main advantage of this approach is that it is not restricted
to proteins for which crystallographic data with bound ligands is available. The resulting family organization from the
separate analysis of both sites (cofactor and substrate) was retrospectively and prospectively validated. Of note, three
hits (inhibition>50% at 10 µM) were identifed for the orphan NSD1
Evaluación del potencial agronómico del fríjol "alado" psophocarpus tetragonolobus (l.) d.c. en las condiciones del valle del cauca
En el ensayo se utilizaron cinco accesiones (lCA-66, UPS-018, UPS-020, UPS-139 y UPS-140) de fríjol alado. Se realizó la caracterización botánica y fenológica del cultivo, aspectos referentes al comportamiento agronómico, fauna insectil que visitó el cultivo, enfermedades que lo afectaron y análisis bromatológico. La accesión de mejor comportamiento fue la ICA-66 ya que registró el mayor rendimiento de semillas por planta (120.13g) y raíces tuberosas por planta (60 g). La accesión UPS–140 presentó el mayor valor de proteína en hojas (25.37 %), vainas (17.86%) y semillas (35.03%).In this research five accessions (ICA-66, UPS-018, UPS-020, UPS-139 and UPS-140) of winged beans were used.

Decoloración de aguas residuales de una industria de pinturas por la microalga Chlorella sp
Objective. Decoloring wastewater from a paint factory making use of Chlorella sp., microalgae as a biological way of treatment. Materials and methods. Samples of this microalgae previously cultivated with nourishing fertilizer under photoperiods of light and darkness were taken to test the microalgae Chlorella sp., initial concentration effect in the bioremoval process. For this purpose, it was cultivated in 0.10, 0.20 and 0.30 units of absorbance in bioreactors with 200 mL wastewater with and without nutrients. The biotest with the best rate of colour removal was chosen and the DBO5 and DQO were marked out. The immobilized Chlorella sp., in kappa carrageenan was also tested. Results. In the tests colour decrease percentage were 81.7, 69.7 and 58.3% without nutrients in the initial concentrations of 0.10, 0.20 and 0.30 units of absorbance respectively and 72.6, 69.0 and 86.8% for 0.10, 0.20 and 0.30 units of absorbance with nutrients respectively in the day of maximum growth. The immobilized microalgae score were 72.60% and 78.36% of color removal for 0.4 and 1.6 units of absorbance respectively. The higher colour removal test score was that with nutrients at 0.30 units of absorbance with several changes in DBO5 and DQO values. Conclusion. The biological wastewater treatment making use of Chlorella sp., microalgae can be considered as an effective choice in decolorating wastewater.Objetivo.

Multiple ATR-Chk1 Pathway Proteins Preferentially Associate with Checkpoint-Inducing DNA Substrates
The ATR-Chk1 DNA damage checkpoint pathway is a critical regulator of the cellular response to DNA damage and replication stress in human cells. The variety of environmental, chemotherapeutic, and carcinogenic agents that activate this signal transduction pathway do so primarily through the formation of bulky adducts in DNA and subsequent effects on DNA replication fork progression. Because there are many protein-protein and protein-DNA interactions proposed to be involved in activation and/or maintenance of ATR-Chk1 signaling in vivo, we systematically analyzed the association of a number of ATR-Chk1 pathway proteins with relevant checkpoint-inducing DNA structures in vitro. These DNA substrates included single-stranded DNA, branched DNA, and bulky adduct-containing DNA. We found that many checkpoint proteins show a preference for single-stranded, branched, and bulky adduct-containing DNA in comparison to undamaged, double-stranded DNA. We additionally found that the association of checkpoint proteins with bulky DNA damage relative to undamaged DNA was strongly influenced by the ionic strength of the binding reaction. Interestingly, among the checkpoint proteins analyzed the checkpoint mediator proteins Tipin and Claspin showed the greatest differential affinity for checkpoint-inducing DNA structures. We conclude that the association and accumulation of multiple checkpoint proteins with DNA structures indicative of DNA damage and replication stress likely contribute to optimal ATR-Chk1 DNA damage checkpoint responses
