A synthetic benzoxazine dimer derivative targets c‐Myc to inhibit colorectal cancer progression

Molecular Oncology, EarlyView.
Benzoxazine dimer derivatives bind to the bHLH‐LZ region of c‐Myc, disrupting c‐Myc/MAX complexes, which are evaluated from SAR analysis. This increases ubiquitination and reduces cellular c‐Myc. Impairing DNA repair mechanisms is shown through proteomic analysis.

The Co-repressor mSin3A Is a Functional Component of the REST-CoREST Repressor Complex

Journal of Biological Chemistry, 2000
The repressor REST/NRSF restricts expression of a large set of genes to neurons by suppressing their expression in non-neural tissues. We find that REST repression involves two distinct repressor proteins. One of these, CoREST, interacts with the COOH-terminal repressor domain of REST (Andres, M. E., Burger, C., Peral-Rubio, M.

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

Molecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

Tuning transcriptional regulation through signaling: A predictive theory of allosteric induction

, 2017
Allosteric regulation is found across all domains of life, yet we still lack simple, predictive theories that directly link the experimentally tunable parameters of a system to its input-output response.

The c1 repressor of bacteriophage P1. Isolation and characterization of the repressor protein.

Journal of Biological Chemistry, 1988
The c1 repressor gene of bacteriophage P1 is located on P1 DNA EcoRI fragment 7 (Sternberg, N. (1979) Virology 96, 129-142). Subfragments of P1 DNA EcoRI fragment 7 were cloned into expression vectors, and the c1 repressor protein from P1 wild-type phage and a revertant of a temperature-sensitive repressor mutant were overproduced in Escherichia coli ...

Two‐way inhibition of PAX5 transcriptional activity by PAX5::CBFA2T3

FEBS Open Bio, EarlyView.
PAX5::CBFA2T3 (PAX5‐C) is a fusion protein of the B‐cell transcription factor, PAX5, and is found in B‐cell ALL. We propose a putative model of two‐way inhibition of PAX5 transcriptional activity by PAX5‐C. There are two ways of repression by PAX5‐C: DNA‐binding‐dependent way and HDAC‐dependent way, with either being sufficient for the repression. HDAC

Bacteriophage 434 Hex Protein Prevents RecA-Mediated Repressor Autocleavage

Viruses, 2013
In a λimm434 lysogen, two proteins are expressed from the integrated prophage. Both are encoded by the same mRNA whose transcription initiates at the PRM promoter. One protein is the 434 repressor, needed for the establishment and maintenance of

Cis‐unsaturated sphingolipids support growth of sphingoid base‐deficient yeast but impair plasma membrane integrity

FEBS Open Bio, EarlyView.
Sphingoid base structures, the sphingolipid backbones, vary among species. We established yeast cells in which the native sphingoid base was replaced with plant‐type bases containing cis or trans double bonds. This is, to our knowledge, the first eukaryotic model mostly composed of sphingolipids containing cis‐unsaturated sphingoid base, providing a ...

Repressor activator protein 1–promoted colorectal cell migration is associated with the regulation of Vimentin

Tumor Biology, 2017
Repressor activator protein 1 plays important roles in telomere protection, while repressor activator protein 1 binds to extra-telomeric DNA and exerts the function as a transcriptional regulator.

Berberine–cinnamic acid co‐crystal effect in ameliorating hyperlipidemia might be regulated through the PI3K/AKT/mTOR/SREBP‐1 signaling pathway

FEBS Open Bio, EarlyView.
Berberine–cinnamic acid co‐crystal (BBR‐CA) inhibits the phosphorylation of the phosphatidylinositol 3‐kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) pathway, suppressing the transfer of pre‐sterol regulatory element‐binding proteins‐1 (SREBP‐1) from the endoplasmic reticulum to the nucleus. This results in a decrease in the expression level of
