Inhibition of human BK polyomavirus replication by small noncoding RNAs
(American Society for Microbiology Journals, 2011)
Small noncoding RNAs regulate a variety of cellular processes, including genomic imprinting, chromatin remodeling, replication, transcription, and translation. Here, we report small replication-regulating RNAs (srRNAs) ...
Kinetics in signal transduction pathways involving promiscuous oligomerizing receptors can be determined by receptor specificity: Apoptosis induction by TRAIL
(American Society for Biochemistry and Molecular Biology, 2012)
Here we show by computer modeling that kinetics and outcome of signal transduction in case of hetero-oligomerizing receptors of a promiscuous ligand largely depend on the relative amounts of its receptors. Promiscuous ...
Cell cycle-dependent mobility of Cdc45 determined in vivo by fluorescence correlation spectroscopy
(Public Library of Science, 2012-04-19)
Eukaryotic DNA replication is a dynamic process requiring the co-operation of specific replication proteins. We measured the mobility of eGFP-Cdc45 by Fluorescence Correlation Spectroscopy (FCS) in vivo in asynchronous ...
Cell cycle-dependent formation of Cdc45-Claspin complexes in human cells is compromized by UV-mediated DNA damage
(Wiley, 2013-08-02)
The replication factor Cdc45 has essential functions in the initiation and elongation steps of eukaryotic DNA replication and plays an important role in the intra-S-phase checkpoint. Its interactions with other replication ...
Nerve Growth Factor in Cancer Cell Death and Survival
(MDPI, 2011-02)
One of the major challenges for cancer therapeutics is the resistance of many tumor cells to induction of cell death due to pro-survival signaling in the cancer cells. Here we review the growing literature which shows that ...
Pectin metabolism and assembly in the cell wall of the charophyte green alga penium margaritaceum
(American Society of Plant Biologists, 2014-03-20)
The pectin polymer homogalacturonan (HG) is a major component of land plant cell walls and is especially abundant in the middle lamella. Current models suggest that HG is deposited into the wall as a highly methylesterified ...
HSP72 Protects Cells from ER Stress-induced Apoptosis via Enhancement of IRE1¿-XBP1 Signaling through a Physical Interaction
(2010)
Endoplasmic reticulum (ER) stress is a feature of secretory cells and of many diseases including cancer, neurodegeneration, and diabetes. Adaptation to ER stress depends on the activation of a signal transduction pathway ...
Mechanisms of ER Stress-Mediated Mitochondrial Membrane Permeabilization
(2010)
During apoptosis, the process of mitochondrial outer membrane permeabilization (MOMP) represents a point-of-no-return as it commits the cell to death. Here we have assessed the role of caspases, Bcl-2 family members and ...
Cognitive analysis of schizophrenia risk genes that function as epigenetic regulators of gene expression
(Wiley, 2016-10-20)
Epigenetic mechanisms are an important heritable and dynamic means of regulating various genomic functions, including gene expression, to orchestrate brain development, adult neurogenesis, and synaptic plasticity. These ...
Bioinformatic identification and analysis of extensins in the plant kingdom
(Public Library of Science, 2016-02-26)
Extensins (EXTs) are a family of plant cell wall hydroxyproline-rich glycoproteins (HRGPs) that are implicated to play important roles in plant growth, development, and defense. Structurally, EXTs are characterized by the ...
