Post-transcriptional control by bacteriophage T4: mRNA decay and inhibition of translation initiation

Virology Journal, 2010
Over 50 years of biological research with bacteriophage T4 includes notable discoveries in post-transcriptional control, including the genetic code, mRNA, and tRNA; the very foundations of molecular biology.

Tonic signaling of the B‐cell antigen‐specific receptor is a common functional hallmark in chronic lymphocytic leukemia cell phosphoproteomes at early disease stages

Molecular Oncology, EarlyView.
B‐cell chronic lymphocytic leukemia (B‐CLL) and monoclonal B‐cell lymphocytosis (MBL) show altered proteomes and phosphoproteomes, analyzed using mass spectrometry, protein microarrays, and western blotting. Identifying 2970 proteins and 316 phosphoproteins, including 55 novel phosphopeptides, we reveal BCR and NF‐kβ/STAT3 signaling in disease ...

cAMP dependent protein kinase regulates expression and post-translational processing of respiratory chain complex I in mammalian cells

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2010
Work is presented on the role of cAMP-dependent protein phosphorylation in post-translational processing and biosynthesis of complex I subunits in mammalian cell cultures. PKA-mediated phosphorylation of the NDUFS4 subunit of complex I promotes in cell cultures in vivo import/maturation in mitochondria of the precursor of this protein.

Ubiquitination of transcription factors in cancer: unveiling therapeutic potential

Molecular Oncology, EarlyView.
In cancer, dysregulated ubiquitination of transcription factors contributes to the uncontrolled growth and survival characteristics of tumors. Tumor suppressors are degraded by aberrant ubiquitination, or oncogenic transcription factors gain stability through ubiquitination, thereby promoting tumorigenesis.

Identification of inhibitors of the Salmonella FraB deglycase, a drug target

FEBS Open Bio, EarlyView.
A high‐throughput screen was used to identify inhibitors of Salmonella FraB, a drug target. Characterization of top hits (identified after an additional counter screen) revealed that some triazolidines, thiadiazolidines, and triazolothiadiazoles are mixed‐type inhibitors of FraB.

STAT3 as a mediator of oncogenic cellular metabolism: Pathogenic and therapeutic implications

Neoplasia: An International Journal for Oncology Research, 2021
The oncogenic transcription factor signal transducer and activator of transcription 3 (STAT3) is activated constitutively in a wide array of human cancers. It is an appealing molecular target for novel therapy as it directly regulates expression of genes

Biological significance of complex N-glycans in plants and their impact on plant physiology

Frontiers in Plant Science, 2014
Asparagine (N)-linked protein glycosylation is a ubiquitous co- and post-translational modification which can alter the biological function of proteins and consequently affects the development, growth and physiology of organisms.

Local search on protein residue networks [PDF]

arXiv, 2013
Self-avoiding random walks were performed on protein residue networks. Compared with protein residue networks with randomized links, the probability of a walk being successful is lower and the length of successful walks shorter in (non-randomized) protein residue networks.

Acacetin reduces endoplasmic reticulum stress through the P‐eNOS/PERK signaling pathway to attenuate MGO‐induced vascular endothelial cell dysfunction

FEBS Open Bio, EarlyView.
We investigated a potential protective effect of acacetin, a naturally occurring flavonoid, against methylglyoxal (MGO)‐induced endothelial dysfunction in human umbilical vein endothelial cells and its mechanism of action. Acacetin can could inhibit MGO‐induced intracellular calcium ion influx, enhance the expression levels of phosphorylated ...

Relationship between the loss of neutralizing antibody binding and fusion activity of the F protein of human respiratory syncytial virus

Virology Journal, 2007
To elucidate the relationship between resistance to HRSV neutralizing antibodies directed against the F protein and the fusion activity of the F protein, a recombinant approach was used to generate a panel of mutations in the major antigenic sites of the
