RNA, Messenger
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
E2F Transcription Factors
A family of basic helix-loop-helix transcription factors that control expression of a variety of GENES involved in CELL CYCLE regulation. E2F transcription factors typically form heterodimeric complexes with TRANSCRIPTION FACTOR DP1 or transcription factor DP2, and they have N-terminal DNA binding and dimerization domains. E2F transcription factors can act as mediators of transcriptional repression or transcriptional activation.

Apoptosis
One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.

Signal Transduction
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

The complexes play an important role in mediating the selective-degradation of short-lived and abnormal proteins. The complex of enzymes can be broken down into three components that involve activation of ubiquitin (UBIQUITIN-ACTIVATING ENZYMES), conjugation of ubiquitin to the ligase complex (UBIQUITIN-CONJUGATING ENZYMES), and ligation of ubiquitin to the substrate protein (UBIQUITIN-PROTEIN LIGASES).

Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

Two-Hybrid System Techniques
Screening techniques first developed in yeast to identify genes encoding interacting proteins. Variations are used to evaluate interplay between proteins and other molecules. Two-hybrid techniques refer to analysis for protein-protein interactions, one-hybrid for DNA-protein interactions, three-hybrid interactions for RNA-protein interactions or ligand-based interactions. Reverse n-hybrid techniques refer to analysis for mutations or other small molecules that dissociate known interactions.

DNA Damage
Injuries to DNA that introduce deviations from its normal, intact structure and which may, if left unrepaired, result in a MUTATION or a block of DNA REPLICATION. These deviations may be caused by physical or chemical agents and occur by natural or unnatural, introduced circumstances. They include the introduction of illegitimate bases during replication or by deamination or other modification of bases; the loss of a base from the DNA backbone leaving an abasic site; single-strand breaks; double strand breaks; and intrastrand (PYRIMIDINE DIMERS) or interstrand crosslinking. Damage can often be repaired (DNA REPAIR). If the damage is extensive, it can induce APOPTOSIS.
Protein Structure, Tertiary
The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.
Mitogen-Activated Protein Kinases
A superfamily of PROTEIN-SERINE-THREONINE KINASES that are activated by diverse stimuli via protein kinase cascades. They are the final components of the cascades, activated by phosphorylation by MITOGEN-ACTIVATED PROTEIN KINASE KINASES, which in turn are activated by mitogen-activated protein kinase kinase kinases (MAP KINASE KINASE KINASES).

p53-dependent G2 arrest associated with a decrease in cyclins A2 and B1 levels in a human carcinoma cell line. (1/89)
In vivo transfer of wild-type (wt) p53 gene via a recombinant adenovirus has been proposed to induce apoptosis and increase radiosensitivity in several human carcinoma models. In the context of combining p53 gene transfer and irradiation, we investigated the consequences of adenoviral-mediated wtp53 gene transfer on the cell cycle and radiosensitivity of a human head and neck squamous cell carcinoma line (SCC97) with a p53 mutated phenotype. We showed that ectopic expression of wtp53 in SCC97 cells resulted in a prolonged G1 arrest, associated with an increased expression of the cyclin-dependent kinase inhibitor WAF1/p21 target gene. A transient arrest in G2 but not in G1 was observed after irradiation. This G2 arrest was permanent when exponentially growing cells were transduced by Ad5CMV-p53 (RPR/INGN201) immediately after irradiation with 5 or 10 Gy. Moreover, levels of cyclins A2 and B1, which are known to regulate the G2/M transition, dramatically decreased as cells arrived in G2, whereas maximal levels of expression were observed in the absence of wtp53. In conclusion, adenoviral mediated transfer of wtp53 in irradiated SCC97 cells, which are mutated for p53, appeared to increase WAF1/p21 expression and decrease levels of the mitotic cyclins A2 and B1. These observations suggest that the G2 arrest resulted from a p53-dependent premature inactivation of the mitosis promoting factor. (+info)Membrane-anchored cyclin A2 triggers Cdc2 activation in Xenopus oocyte. (2/89)
In Xenopus oocyte, the formation of complexes between neosynthesized cyclins and Cdc2 contributes to Cdc2 kinase activation that triggers meiotic divisions. It has been proposed that cytoplasmic membranes could be involved in this process. To investigate this possibility, we have injected in the oocyte two undegradable human cyclin A2 mutants anchored to the endoplasmic reticulum (ER) membrane. They encode fusion proteins between the truncated cyclin A2-Delta152 and a viral or cellular ER-targeting domain. We show that both mutants are fully functional as mitotic cyclins when expressed in Xenopus oocytes, bind Cdc2 and activate M-phase promoting factor. (+info)Centrosome overduplication, increased ploidy and transformation in cells expressing endoplasmic reticulum-associated cyclin A2. (3/89)
Cyclin A2 is predominantly, but not exclusively, localized in the nucleus from G1/S transition onwards. It is degraded when cells enter mitosis after nuclear envelope breakdown. We previously showed that a fusion protein (S2A) between the hepatitis B virus (HBV) surface antigen protein and a non-degradable fragment of human cyclin A2 (Delta152) resides in the endoplasmic reticulum membranes, escapes degradation and transforms normal rat fibroblasts. The present study investigates whether cytoplasmic cyclin A2 may play a role in oncogenesis. We show that the sequestration of non-degradable cyclin A2-Delta152 by a cellular ER targeting domain (PRL-A2) leads to cell transformation when coexpressed with activated Ha-ras. REF52 cells constitutively expressing PRL-A2 are found to have a high incidence of multinucleate giant cells, polyploidy and abnormal centrosome numbers, giving rise to the nucleation of multipolar spindles. Injection of these cells into athymic nude mice causes tumors, even in the absence of a cooperating Ha-ras oncogene. These results demonstrate that, independently of any viral context, an intracellular redistribution of non-degradable cyclin A2 is capable of deregulating the normal cell cycle to the point where it promotes aneuploidy and cancer. (+info)Murine spermatogonial stem cells: targeted transgene expression and purification in an active state. (4/89)
A 400 bp fragment of the spermatogonia-specific Stra8 locus was sufficient to direct gene expression to the germinal stem cells in transgenic mice. A fractionation procedure was devised, based on immunomagnetic sorting of cells in which the promoter drives the expression of a surface functionally neutral protein tag. The purified cells expressed the known molecular markers of spermatogonia Rbm, cyclin A2 and EP-Cam, and the beta1- and alpha6-integrins characteristic of the stem cell fraction. A 700-fold enrichment in stem cells was determined by the ability of the purified fractions to re-establish spermatogenesis in germ cell-depleted recipient testes. (+info)Increased hepatic Forkhead Box M1B (FoxM1B) levels in old-aged mice stimulated liver regeneration through diminished p27Kip1 protein levels and increased Cdc25B expression. (5/89)
Recent liver regeneration studies indicate that maintaining hepatic Forkhead Box M1B (FoxM1B) expression in 12-month-old (old-aged) Transthyretin-FoxM1B transgenic mice increases hepatocyte proliferation and expression of cell cycle regulatory genes. Because these transgenic CD-1 mice maintain FoxM1B levels during the aging process, we conducted the current study to determine whether adenovirus delivery of the FoxM1B gene (AdFoxM1B) is sufficient to stimulate liver regeneration in old-aged Balb/c mice. Here we show that AdFoxM1B infection of old-aged mice caused a significant increase in FoxM1B expression, hepatocyte DNA replication, and mitosis following partial hepatectomy. This stimulation in hepatocyte S-phase progression was associated with diminished protein expression and perinuclear localization of cyclin-dependent kinase (Cdk) inhibitor p27(Kip1) (p27) protein following partial hepatectomy. In contrast, old-aged mice infected with control virus displayed high hepatocyte levels of p27 protein, which had been localized to the nucleus prior to S-phase. Furthermore, we found that restoring FoxM1B expression did not influence p27 mRNA levels, and this new finding implicates FoxM1B in regulation of p27 protein levels. Likewise, AdFoxM1B-infected regenerating livers displayed elevated S-phase levels of Cdk2 kinase activity compared with old-aged mice infected with control virus. Furthermore, restoring FoxM1B expression in old-aged mice caused elevated levels of Cyclin B1, Cyclin B2, Cdc25B, Cdk1, and p55CDC mRNA as well as stimulating Cdc25B nuclear localization during liver regeneration, all of which are required for mitosis. These studies indicated that an acute delivery of the FoxM1B gene in old-aged mice is sufficient to re-establish proliferation of regenerating hepatocytes, suggesting that FoxM1B can be used for therapeutic intervention to alleviate the reduction in cellular proliferation observed in the elderly. (+info)B-Myb overcomes a p107-mediated cell proliferation block by interacting with an N-terminal domain of p107. (6/89)
B-Myb is a cell-cycle regulated transcription factor which is implicated in cell proliferation and has an essential role in early embryonic development. In this study we examined the functions of B-Myb required to overcome G1 arrest in Saos-2 cells induced by the retinoblastoma-related p107 protein. Our results demonstrated that this activity was independent of B-Myb transactivation function, but correlated with its capacity to form an in vivo complex with p107. A large proportion of B-Myb formed complexes with p107 in cotransfected cells, however, B-Myb bound weakly to the related p130 protein and not at all to pRb. In contrast to the E2F transcription factors, which bind the p107 C-terminal pocket domain, B-Myb recognizes an N-terminal p107 region which overlaps the larger cyclin-binding domain. B-Myb and cyclin A2 formed mutually exclusive complexes with p107, and B-Myb enhanced the activity of co-transfected cyclin E kinase activity, implying that B-Myb affects the cell cycle by preventing sequestration of active cyclin/cdk2 complexes. This study defines a novel function of B-Myb and further suggests that the p107 N-terminus provides an interaction domain for transcription factors involved in cell cycle control. (+info)The cell cycle-regulated B-Myb transcription factor overcomes cyclin-dependent kinase inhibitory activity of p57(KIP2) by interacting with its cyclin-binding domain. (7/89)
The cell cycle-regulated B-Myb transcription factor is required for early embryonic development and is implicated in regulating cell growth and differentiation. In addition to its transcriptional regulatory properties, recent data indicate that B-Myb can release active cyclin/Cdk2 activity from the retinoblastoma-related p107 protein by directly interacting with the p107 N terminus. As this p107 domain has homology to the cyclin-binding domains of the p21(Waf1/Cip1) family of cyclin-dependent kinase inhibitors (CKIs), we investigated in this study whether B-Myb could also interact with these CKIs. No in vivo interaction was found with either p21(Waf1/Cip1) or p27(KIP1), however, binding to p57(KIP2) was readily detectable in both in vivo and in vitro assays. The B-Myb-interacting region of p57(KIP2) mapped to the cyclin-binding domain. Consistent with this, B-Myb competed with cyclin A2 for binding to p57(KIP2), resulting in release of active cyclin/Cdk2 kinase. Moreover, B-Myb partially overcame the ability of p57(KIP2) to induce G1 arrest in Saos-2 cells. Despite similarities with previous p107 studies, the B-Myb domains required for interaction with p57(KIP2) were quite different from those implicated for p107. Thus, it is evident that B-Myb may promote cell proliferation by a non-transcriptional mechanism that involves release of active cyclin/Cdk2 from p57(KIP2) as well as p107. (+info)Synchronization of interphase events depends neither on mitosis nor on cdk1. (8/89)
Human HT2-19 cells with a conditional cdk1 mutation stop dividing upon cdk1 inactivation and undergo multiple rounds of endoreplication. We show herein that major cell cycle events remain synchronized in these endoreplicating cells. DNA replication alternates with gap phases and cell cycle-specific cyclin E expression is maintained. Centrosomes duplicate in synchrony with chromosome replication, giving rise to polyploid cells with multiple centrosomes. Centrosome migration, a typical prophase event, also takes place in endoreplicating cells. The timing of these events is unaffected by cdk1 inactivation compared with normally dividing cells. Nuclear lamina breakdown, in contrast, previously shown to be dependent on cdk1, does not take place in endoreplicating HT2-19 cells. Moreover, breakdown of all other major components of the nuclear lamina, like the inner nuclear membrane proteins and nuclear pore complexes, seems also to depend on cdk1. Interestingly, the APC/C ubiquitin ligase is activated in these endoreplicating cells by fzr but not by fzy. The oscillations of interphase events are thus independent of cdk1 and of mitosis but may depend on APC/Cfzr activity. (+info)
