How can I increase the transduction efficiency with the BacMam 2.0 reagents such as the the CellLight and Premo products?
Try varying particle-to-cell ratio (PPC), incubation volume, temperature and, cell density (if adherent cells are transduced). For adherent cells, we recommend a confluence of about 70%. Following the PPC, adjusting the volume is the next best parameter to change to optimize protein expression. If that doesn't work, you can also use the BacMam Enhancer Kit (Cat. No. B10107).
CapZ and actin capping dynamics increase in myocytes after a bout of exercise and abates in hours after stimulation ends.

'The time course of the response and recovery after acute activity seen in exercise is not well understood. The goal of this work is to address how proteins of the thin filament (actin and its capping protein CapZ) are changed by 1 h of mechanical stimulation and return to baseline ... More
Stress fibers stabilize the position of intranuclear DNA through mechanical connection with the nucleus in vascular smooth muscle cells.

Actin stress fibers (SFs) running across the top surface of the nucleus in vascular smooth muscle cells were dissected using laser nano-dissection technique to release its pretension, and the dynamic behavior of SFs, nucleus, and intranuclear DNA were investigated. SFs shortened across the top surface of the nuclei after their ... More
Human disease locus discovery and mapping to molecular pathways through phylogenetic profiling.

Genes with common profiles of the presence and absence in disparate genomes tend to function in the same pathway. By mapping all human genes into about 1000 clusters of genes with similar patterns of conservation across eukaryotic phylogeny, we determined that sets of genes associated with particular diseases have similar ...

Phosphatidylinositol 4,5-bisphosphate regulates CapZß1 and actin dynamics in response to mechanical strain.
Authors:Li J, Russell B,
Journal:
PubMed ID:24043251
Mechanical stress causes filament remodeling leading to myocyte hypertrophy and heart failure. The actin capping protein Z (CapZ) tightly binds to the barbed end of actin filaments, thus regulating actin assembly. The hypothesis is that the binding between CapZ and the actin filament is modulated through phosphatidylinositol 4,5-bisphosphate (PIP2) and ... More
Evaluation of nanoparticle uptake in co-culture cancer models.
Co-culture models are currently bridging the gap between classical cultures and in vivo animal models. Exploring this novel approach unlocks the possibility to mimic the tumor microenvironment in vitro, through the establishment of cancer-stroma synergistic interactions. Notably, these organotypic models offer a perfect platform for the development and pre-clinical evaluation ... More
