Beyond the well-known role in the G1→S transition, MYC is also involved in the G2-M cell cycle phases regulation.
To further illustrate the early changes of M phase regulation, we mapped the up-regulated regulatory event frequencies of four stages (very early, early, advance and very advance HCC stages) on a KEGG cell cycle pathway (hsa04110).
One hypothesis of circadian phase regulation is that different circadian genes are regulated by different subsets (combinatorial) of TFs.
We therefore compared the phases of the robust circadian transcriptome (FDR <0.05) in multiple tissues in [ 33] against the analyzed ChIP-seq data for E-box activators, D-box repressor and RRE regulators in order to check for characteristic patterns of phase regulation by these TFs.
Therefore, our results fully demonstrate that SWCNTs exhibit dual-phase regulation to plant cells in natural environment.
Herein we are the first to report that single-walled carbon nanotubes (SWCNTs) exhibit dual-phase regulation to Arabidopsis mesophyll cells exposed to different concentration of SWCNTs.
In particular, the test case shows a two-phase regulation experiment, commanding both position and attitude to reach specified final state vectors.
Moreover, the siMDR1 loaded PL-dendriplexes worked synergistically with paclitaxel (PTX) for treating MDR, leading to increased cell apoptosis and cell phase regulation.
In conclusion, single walled carbon nanotubes can get through Arabidopsis mesophyll cell wall and membrane, and exhibit dose-dependent dual-phase regulation to Arabidopsis mesophyll protoplasts such as low dose stimulating cell growth, and high dose inducing cells' ROS generation, necrosis or apoptosis.
In my hands, at least the transcription of the luxS mRNA but not the protein is under growth phase regulation, most likely involving σS.
Most of what is known about G1 phase regulation came originally from studies utilizing cells synchronized by serum starvation, contact inhibition, thymidine blocks or drugs [18].
