Also, some substances pass out of cells into the apoplast and are transported by energy-requiring processes into the protoplast of another cell.
In a cell model obtained by in vitro passing of K562 cells in progressively increasing doses of doxorubicin, overexpression of MDR1 gene was shown to confer resistance to imatinib [16].
We found that GBC-SD cells in control group passed more of the Transwell membrane and had more invasive capability than TIMP-2 or NCTD group in vitro; the number of passing membrane cells i.e, invated tumor cells in TIMP-2 or NCTD group markedly decreased.
Moreover, a proteomic approach has revealed that H19 overexpression in human cancerous mammary epithelial cells positively regulated the thioredoxin gene at the post-transcriptional level, thioredoxin being a key protein of the oxidative stress response and in the reduction of ribonucleotides to deoxyribonucleotides enabling DNA synthesis and the passing of the cells through the S-phase.
To reach C Wing, you pass a row of cells where condemned men spent their last night before being led to the gallows.
While each monkey practiced the new skill, researchers "listened in" on the distinct patterns of electrical messages passing among the cells of his visual cortex.
By measuring side-scatter signals emanating from passing cells, the degree of cytoplasmic granularity or size of lipid droplets of single cells can be obtained.
The authors of the study surmise that perhaps fish oil improves cognition by reducing inflammation or boosting the strength of signals passing among brain cells, or by improving the availability of dopamine in other parts of the brain.
It is one of the more recent additions for treatment in MS. It is thought that natalizumab exerts its therapeutic efficacy by blocking the pass of T cells, a specific immune cell which plays a major role in the pathogenesis of MS, through the blood brain barrier, thus preventing these cells reach the central nervous system.
These ratios are changed by passing through the cells of living organisms, a process called fractionation.
