AP4 is required for mitogen- and c-MYC-induced cell cycle progression
AP4 represents a c-MYC-inducible bHLH-LZ transcription factor, which displays elevated expression in many types of tumors. We found that serum-starved AP4-deficient mouse embryo fibroblasts (MEFs) were unable to resume proliferation and showed a delayed S-phase entry after restimulation. Furthermore, they accumulated as tetraploid cells due to a cytokinesis defect. In addition, AP4 was required...
متن کاملMYC-repressed long noncoding RNAs antagonize MYC-induced cell proliferation and cell cycle progression
The transcription factor MYC is a proto-oncogene regulating cell proliferation, cell cycle, apoptosis and metabolism. The recent identification of MYC-regulated long noncoding RNAs (lncRNAs) expands our knowledge of the role of lncRNAs in MYC functions. Here, we identify MYC-repressed lncRNAs named MYCLo-4, -5 and -6 by comparing 3 categories of lncRNAs (downregulated in highly MYC-expressing c...
متن کاملTBX5 is required for embryonic cardiac cell cycle progression.
Despite the critical importance of TBX5 in normal development and disease, relatively little is known about the mechanisms by which TBX5 functions in the embryonic heart. Our present studies demonstrate that TBX5 is necessary to control the length of the embryonic cardiac cell cycle, with depletion of TBX5 leading to cardiac cell cycle arrest in late G(1)- or early S-phase. Blocking cell cycle ...
متن کاملWWP2 is required for normal cell cycle progression
WWP2 is a ubiquitin E3 ligase belonging to the Nedd4-like family. Given that WWP2 target proteins including PTEN that are crucial for regulating cell proliferation or suppressing tumorigenesis, we have asked whether WWP2 plays a role in controlling cell cycle progression. Here we report that WWP2 is necessary for normal cell cycle progression as its silencing significantly reduces the cell prol...
متن کاملThe vacuole/lysosome is required for cell-cycle progression
Organelles are distributed to daughter cells, via inheritance pathways. However, it is unclear whether there are mechanisms beyond inheritance, which ensure that organelles are present in all cells. Here we present the unexpected finding that the yeast vacuole plays a positive essential role in initiation of the cell-cycle. When inheritance fails, a new vacuole is generated. We show that this o...
