Abstract
It is long been suggested that one-carbon metabolism (OCM) is associated with Alzheimer's disease (AD), whereas the potential mechanisms remain poorly understood. Taking advantage of chemical biology, that mitochondrial serine hydroxymethyltransferase (SHMT2) directly regulated the translation of ADAM metallopeptidase domain 10 (ADAM10), a therapeutic target for AD is reported. That the small-molecule kenpaullone (KEN) promoted ADAM10 translation via the 5' untranslated region (5'UTR) and improved cognitive functions in APP/PS1 mice is found. SHMT2, which is identified as a target gene of KEN and the 5'UTR-interacting RNA binding protein (RBP), mediated KEN-induced ADAM10 translation in vitro and in vivo. SHMT2 controls AD signaling pathways through binding to a large number of RNAs and enhances the 5'UTR activity of ADAM10 by direct interaction with GAGGG motif, whereas this motif affected ribosomal scanning of eukaryotic initiation factor 2 (eIF2) in the 5'UTR. Together, KEN exhibits therapeutic potential for AD by linking OCM with RNA processing, in which the metabolic enzyme SHMT2 "moonlighted" as RBP by binding to GAGGG motif and promoting the 5'UTR-dependent ADAM10 translation initiation.

Abstract
Krüppel-like factor 4 (KLF4) is a member of the KLF transcription factor family containing zinc-fingers, and is involved in the regulation of apoptosis, proliferation and differentiation of B cells and B-cell malignancies. KLF4 can act like an oncogene, we shown that KLF4 overexpression correlated with poor prognostic and chemoresistance in B-NHL. In addition, we shown that KLF4 is regulated by YY1. In this study, we demonstrate that chemical inhibition of KLF4 by Kenpaullone, results in suppression of proliferation, cell survival, downregulation of Bcl-2 and increases apoptosis in B-NHL cell lines through YY1 independent pathway. Combination of Kenpaullone and Doxorubicin, increased apoptosis. The co-expressions of KLF4/YY1 or KLF4/Bcl-2 in NHL was analyzed using Oncomine Database, exhibiting a positive correlation of expression. The present findings suggest that the chemical inhibition of KLF4 by Kenpaullone treatment could be a potential therapeutic alternatively in KLF4+ lymphomas.

Abstract
The selection and validation of bioactive compounds require multiple approaches, including in-depth analyses of their biological activity in a whole-animal context. We exploited the sea urchin embryo in a rapid, medium-scale range screening to test the effects of the small synthetic kinase inhibitor kenpaullone. We show that sea urchin embryos specifically respond to this molecule depending on both dose and timing of administration. Phenotypic effects of kenpaullone are not immediately visible, since this molecule affects neither the fertilization nor the spatial arrangement of blastomeres at early developmental stages. Nevertheless, kenpaullone exposure from the beginning of embryogenesis profoundly perturbs specification, detachment from the epithelium, and migration of the primary mesenchyme cells, thus affecting the whole embryonic epithelial mesenchymal transition process. Our results reaffirm the sea urchin embryo as an excellent and sensitive in vivo system, which provides straightforward and rapid response to external stimuli.
