Connexins in the intracellular (cytoplasmic or nuclear) compartment may control tumor progression, modulating the expression of the genes responsible for cell growth regulation, differentiation and apoptosis, and other functions of cancerous cells.
Altogether, these data strongly suggest that Jen1 is ubiquitylated at the plasma membrane and is deubiquitylated after its internalization, and lead us to propose that a second, glucose-regulated ubiquitylation step at the TGN involving Rsp5 and Rod1 may control Jen1 progression from the TGN to the vacuole.
Our data thus suggest that the relative levels of abortive D-loop synthesis versus complete mtDNA replication are regulated and may provide a mechanism to control progression to complete mtDNA replication.
Our data also suggest that SCD1 may control cell cycle progression by altering the levels of cyclin D1 and CDK6, two proteins whose expression and interaction are critical for the passage of cycling cells through G1/S transition [27].
These results suggest that MMP-1 expression of both stromal and tumour cells may control breast cancer progression.
Some recent reports suggest that NME1 may control cell cycle progression [ 37], and histidine-dependent protein phosphorylation [ 38, 39] and transcription [ 34, 40].
Our results not only identified mortalin as a new CD9 partner, but also clarify the mechanisms by which CD9 may control prostate cancer progression.
In addition to inhibition of apoptosis, activated NF-κB may control cell cycle progression by regulating the expression of important cell cycle regulatory proteins such as cyclin D1 andcyclin dependent kinase 2 (CDK2), further contributing to the tumour growth [ 38].
As hinted by previous reports, the presence of SCDs in several SAC proteins such as Bub1, Mad1, and Cdc20 indicates Tel1 and/or Mec1 may control cell cycle progression at the metaphase-anaphase transition in addition to their well-known roles in the G2/M, G1 and S checkpoints [ 20, 21].
Therefore, mucosal vaccination with GroEL may control inflammation and the progression of atherosclerosis due to periodontopathic bacterial infection.
