SUMOylation regulates LKB1 localization and its oncogenic activity in liver cancer
(Elsevier, 2019)
BACKGROUND: Even though liver kinase B1 (LKB1) is usually described as a tumor suppressor in a wide variety of tissues, it has been shown that LKB1 aberrant expression is associated with bad prognosis in Hepatocellular ...

Cytochrome c: Surfing Off of the Mitochondrial Membrane on the Tops of Complexes III and IV
(Elsevier, 2019)
The proper arrangement of protein components within the respiratory electron transport chain is nowadays a matter of intense debate, since altering it leads to cell aging and other related pathologies. Here, we discuss ...

Base-Promoted, Remote C−H Activation at a Cationic (η5 ‑C5Me5)Ir(III) Center Involving Reversible C−C Bond Formation of Bound C5Me5
(American Chemical Society, 2019)
C-H bond activation at cationic [(η5-C5Me5)Ir(PMe2Ar')] centers is described, where PMe2Ar' are the terphenyl phosphine ligands PMe2ArXyl2 and PMe2ArDipp2. Different pathways are defined for the conversion of the five-coordinate ...

Double asymmetric hydrogenation of conjugated dienes: a self-breeding chirality route for C2 symmetric 1,4-diols
(Royal Society of Chemistry, 2019)
The synthesis and double asymmetric hydrogenation of (Z,Z)-1,3- diene-1,4-diyl diacetates is described. In this reaction C2/meso ratios up to 85 : 15 and enantioselectivities up to 97% ee have been achieved. As the ...

Palladium-mediated Intramolecular Dearomatization of Ligated Dialkylterphenyl Phosphines
(Royal Society of Chemistry, 2019)
Aryl-Pd(ii) chlorides stabilized by dialkylterphenyl phosphine ligands undergo a thermal isomerization process, leading to the formation of allyl-Pd(ii)-chloride species. The transformation involves the intramolecular ...

HuR biological function involves RRM3-mediated dimerization and RNA binding by all three RRMs
(Oxford University Press, 2019)
HuR/ELAVL1 is an RNA-binding protein involved in differentiation and stress response that acts primarily by stabilizing messenger RNA (mRNA) targets. HuR comprises three RNA recognition motifs (RRMs) where the structure ...

Monomeric alkoxide and alkylcarbonate complexes of nickel and palladium stabilized with the iPrPCP pincer ligand: a model for the catalytic carboxylation of alcohols to alkyl carbonates
(Royal Society of Chemistry, 2019)
Monomeric alkoxo complexes of the type [(iPrPCP)M-OR] (M = Ni or Pd; R = Me, Et, CH2CH2OH; iPrPCP = 2,6-bis(diisopropylphosphino)phenyl) react rapidly with CO2 to afford the corresponding alkylcarbonates [(iPrPCP)M-OCOOR]. ...
