Lactylation in cancer biology: Unlocking new avenues for research and therapy

Cancer Communications, EarlyView.
Abstract Lactylation, a newly identified post‐translational modification, plays a multifaceted role in cancer biology by integrating epigenetic and non‐epigenetic mechanisms. This review summarizes the latest research progress on lactylation, including its functions in epigenetic regulation and its broader impact on cellular processes.

Assignments of backbone 1H, 13C and 15N resonances in H-Ras (1–166) complexed with GppNHp at physiological pH [PDF]

, 2012
The small GTPase Ras is an important signaling molecule acting as a molecular switch in eukaryotic cells. Recent findings of global conformational exchange and a putative allosteric binding site in the G domain of Ras opened an avenue to understanding ...

Photocaged Dinucleoside Tetraphosphates for Light‐Mediated Activation of 5′ Cap Interactions and Translation In Vitro

ChemistryEurope, EarlyView.
Photocaged dinucleoside tetraphosphates can be incorporated into mRNA by T7 RNA polymerase. Subsequent irradiation with light activates 5′ cap interactions and translation. These 5′ cap analogs are useful tools to probe the functions of naturally occurring dinucleoside tetraphosphates and their role in bacteria and mammalian cells.

Suppression of the biosynthesis of guanosine triphosphate by protein synthesis inhibitors.

Journal of Biological Chemistry, 1980
In a prior report (Pike, L.M., Khym, J.X., Jones, M.H., Lee, W.H., and Volkin, E. (1980) J. Biol. Chem. 255, 3340-3347), it was observed that CTP synthesis and concomitant incorporation of CMP into RNA and dCMP into DNA were markedly reduced in cells cultured in the presence of cycloheximide and puromycin.

ARC Expands the DAAM1 Microexon‐Mediated Actin–RHOA/ROCK Interplay

Cytoskeleton, EarlyView.
ABSTRACT Actin cytoskeleton and its dynamics play a crucial role in synaptic function, influencing dendritic spines' structural and functional plasticity. Recent findings unveiled the significance of alternative splicing of a neural‐specific microexon in DAAM1 in modulating actin's role in synaptic processes.

An Effector of Hemoglobin Structure: The Guanosine 3', 5'-Triphosphate

Croatica Chemica Acta, 2012
The effect of guanosine 3', 5'-triphosphate (GTP) on the hemoglobin structure was studied by UV-visible, fluorescence and circular dichroism (CD) spectroscopies, and cyclic voltammetry. UV-visible absorption spectra showed an increase in absorbance in the regions of 420 nm and 280 nm.
