Surprisingly, we found that P-cadherin retroviral transduction of MCF-7/AZ breast cancer cells (E-cadherin positive) did not produce striking changes in cell-cell aggregation, which suggested that P-cadherin does not shift the balance of aggregation established by the endogenous cadherin in this system [ 54].
In addition to this striking change in cell shape, we observed that none of the B16-GFP cells secrete melanin (Figure 1A).
Although the overall number of Müller glia was not changed by the P6 DM treatment, there were several striking changes in these cells.
Despite the striking changes in the arrested cells, particularly with regards to the global arrest in protein synthesis, the cell-cycle arrest was reversible suggesting that VSG synthesis and/or deposition on the cell-surface is possibly being monitored as part of a normal cell-cycle checkpoint.
Our laboratory has studied the phenotypic response of cells to simulated microgravity, and observed striking changes in the establishment of cell polarity, bipolar budding pattern, and cell separation [ 13].
Striking changes in the proportions of cells undergoing apoptotic or necrotic death were not observed.
Focusing in the 0.25 and 1.0 μM 5-aza-CdR-treated cells, conditions that showed striking changes in DNA methylation, we allowed the treated cells to recover and grow in culture for a further 30 days, observing that the growth rates return to pre-treatment levels while cellular metabolic rates recover almost completely during this period.
One of the hallmarks of successful vaccination is the induction of strong and persistent memory T cell responses, a process that involves striking changes in the number and functional properties of T cells.
Second, we show that loss of BNIP3 causes profound morphological alterations of melanoma cells coupled with striking changes in the dynamic organization of the actin filaments, required to form lamellipodia and filopodia, driving cell migration.
Scanning electron microscopy analysis showed that cells exhibited striking changes in morphology after PFB domestication.
