Poly(b-L-malate) (PMLA) has been reported as an uncon-ventional, physiologically important biopolymer in plasmo-dia of myxomycetes, and has been proposed to function in the storage and transport of nuclear proteins by mimicking the phospho(deoxy)ribose backbone of nucleic acids. It is distributed in the cytoplasm and especially in the nuclei of these giant, multinucleate cells. We report here for the first time an increase in growth rate and a shortening of the cell cycle after the injection of purified PMLA. ...

The naturally synchronous plasmodia of myxomycetes synthesize poly(b-L-malic acid), which carries out cell-specific functions. In Physarum polycephalum, poly(b-L-malate) [the salt form of poly(b-L-malic acid)] is highly concentrated in the nuclei, repressing DNA synthetic activity of DNA polymerases by the formation of reversible complexes. To test whether this inhibitory activity is cell-cycle-dependent, purified DNA polymerase a of P.

Sterol regulatory element-binding proteins 1 and 2 (SREBP-1 and SREBP-2) are important regulators of genes involved in cholesterol and fatty acid metabolism, but have also been implicated in the regulation of the cell cycle and have been associated with the pathogenesis of type 2 diabetes, atherosclerosis and obesity, among others.

Figure 80-1 Induction of p53 by the DNA damage and oncogene checkpoints. In response to noxious stimuli, p53 and mdm2 are phosphorylated by the ataxia telangiectasia mutated (ATM) and related ATR serine/threonine kinases, as well as the immediated downstream checkpoint kinases, Chk1 and Chk2. This causes dissociation of p53 from mdm2, leading to increased p53 protein levels and transcription of genes leading to cell cycle arrest (p21Cip1/Waf1) or apoptosis (e.g., the proapoptotic Bcl-2 family members Noxa and Puma).

Some limited understanding of self-renewal exists and, intriguingly, implicates gene products that are associated with the chromatin state, a high-order organization of chromosomal DNA that influences transcription. These include members of the polycomb family, a group of zinc finger–containing transcriptional regulators that interact with the chromatin structure, contributing to the accessibility of groups of genes for transcription.

Signaling Pathways Downstream of Rtks: Ras and PI3K Several oncogene and tumor-suppressor gene products are components of signal transduction pathways that emanate from RTK activation (Fig. 80-2). The most extensively studied are the Ras/mitogen-activated protein (MAP) kinase pathway and the phosphatidylinositol-3-kinase (PI3K) pathway, both of which regulate multiple processes in cancer cells, including cell cycle progression, resistance to apoptotic signals, angiogenesis, and cell motility.
