A telomere-independent senescence mechanism is the sole barrier to Syrian hamster cell immortalization. (1/2283)

Reactivation of telomerase and stabilization of telomeres occur simultaneously during human cell immortalization in vitro and the vast majority of human cancers possess high levels of telomerase activity. Telomerase repression in human somatic cells may therefore have evolved as a powerful resistance mechanism against immortalization, clonal evolution and malignant progression. The comparative ease with which rodent cells immortalize in vitro suggests that they have less stringent controls over replicative senescence than human cells. Here, we report that Syrian hamster dermal fibroblasts possess substantial levels of telomerase activity throughout their culture life-span, even after growth arrest in senescence. In our studies, telomerase was also detected in uncultured newborn hamster skin, in several adult tissues, and in cultured fibroblasts induced to enter the post-mitotic state irreversibly by serum withdrawal. Transfection of near-senescent dermal fibroblasts with a selectable plasmid vector expressing the SV40 T-antigen gene resulted in high-frequency single-step immortalization without the crisis typically observed during the immortalization of human cells. Collectively, these data provide an explanation for the increased susceptibility of rodent cells to immortalization (and malignant transformation) compared with their human equivalents, and provide evidence for a novel, growth factor-sensitive, mammalian senescence mechanism unrelated to telomere maintenance.

Growth-inhibitory effect of cyclic GMP- and cyclic AMP-dependent vasodilators on rat vascular smooth muscle cells: effect on cell cycle and cyclin expression. (2/2283)

1. The possibility that the antiproliferative effect of cyclic GMP- and cyclic AMP-dependent vasodilators involves an impaired progression of vascular smooth muscle cells (VSMC) through the cell cycle and expression of cyclins, which in association with the cyclin-dependent kinases control the transition between the distinct phases of the cell cycle, was examined. 2. FCS (10%) stimulated the transition of quiescent VSMC from the G0/G1 to the S phase (maximum within 18-24 h and then to the G2/M phase (maximum within 22-28 h). Sodium nitroprusside and 8-Br-cyclic GMP, as well as forskolin and 8-Br-cyclic AMP markedly reduced the percentage of cells in the S phase after FCS stimulation. 3. FCS stimulated the low basal protein expression of cyclin D1 (maximum within 8-24 h) and E (maximum within 8-38 h) and of cyclin A (maximum within 14-30 h). The stimulatory effect of FCS on cyclin D1 and A expression was inhibited, but that of cyclin E was only minimally affected by the vasodilators. 4. FCS increased the low basal level of cyclin D1 mRNA after a lag phase of 2 h and that of cyclin A after 12 h. The vasodilators significantly reduced the FCS-stimulated expression of cyclin D1 and A mRNA. 5. These findings indicate that cyclic GMP- and cyclic AMP-dependent vasodilators inhibit the proliferation of VSMC by preventing the progression of the cell cycle from the G0/G1 into the S phase, an effect which can be attributed to the impaired expression of cyclin D1 and A.

Mycophenolate mofetil inhibits rat and human mesangial cell proliferation by guanosine depletion. (3/2283)

BACKGROUND: Mycophenolate mofetil (MMF) is used for immunosuppression after renal transplantation because it reduces lymphocyte proliferation by inhibiting inosine monophosphate dehydrogenase (IMPDH) in lymphocytes and GTP biosynthesis. In the present study we asked if therapeutic concentrations of MMF might interfere with mesangial cell (MC) proliferation which is involved in inflammatory proliferative glomerular diseases. METHODS: Rat and human MCs were growth-arrested by withdrawal of fetal calf serum (FCS) and stimulated by addition of FCS, platelet-derived growth factor (PDGF) or lysophosphatidic acid (LPA). Different concentrations of MMF (0.019-10 microM) were added concomitantly in the presence or absence of guanosine. MC proliferation was determined by [3H]thymidine incorporation. Cell viability was assessed by trypan blue exclusion. Apoptotic nuclei were stained using the Hoechst dye H33258. Cytosolic free Ca2+ concentrations were determined with the fluorescent calcium chelator fura-2-AM. RESULTS: MMF inhibited mitogen-induced rat MC proliferation with an IC50 of 0.45 +/- 0.13 microM. Human MCs proved to be even more sensitive (IC50 0.19 +/- 0.06 microM). Inhibition of MC proliferation was reversible and not accompanied by cellular necrosis or apoptosis. Addition of guanosine prevented the antiproliferative effect of MMF, indicating that inhibition of IMPDH is responsible for decreased MC proliferation. Early signalling events of GTP-binding-protein-coupled receptors, such as changes in intracellular Ca2+ levels were not affected by MMF. CONCLUSIONS: The results show that MMF has a concentration-dependent antiproliferative effect on cultured MCs in the therapeutic range, which might be a rationale for the use of this drug in the treatment of mesangial proliferative glomerulonephritis.

Altered expression of the IGF-1 receptor in a tamoxifen-resistant human breast cancer cell line. (4/2283)

The relationship between oestrogen (E2) and insulin-like growth factor-one (IGF-1) was examined in both tamoxifen-sensitive (MCF 7/5-21) and tamoxifen-resistant (MCF 7/5-23) subclones of the MCF 7 cell line. Both subclones were grown in defined, serum-free (SF) medium over a period of 7 days with the addition of E2 or IGF-1 or a combination of both agents. Growth of both MCF 7/5-21 and 7/5-23 cells was stimulated (245% and 350%, respectively) by E2. However, only the growth of MCF 7/5-23 cells was stimulated (266%) by IGF-1. A combination of E2 and IGF-1 significantly enhanced MCF 7/5-21 and 7/5-23 cell growth (581% and 695%, respectively). E2-induced IGF-1 receptor (IGF-1R) levels (as measured by 125I-IGF-1 binding and Northern analyses) in only MCF 7/5-23 cells. This effect was partially inhibited by tamoxifen. In medium containing serum, the growth of only the MCF 7/5-23 cells was significantly inhibited by the IGF-1R monoclonal antibody, alphaIR-3. The detection of E2-induced expression of IGF-2 using RT-PCR was demonstrated in the MCF 7/5-23 cells. These experiments indicate that E2 may sensitize tamoxifen-resistant MCF 7/5-23 cells to the growth stimulatory actions of IGF-2 via up-regulation of the IGF-1R and describes a cell-survival mechanism that may manifest itself as tamoxifen resistance.

Protection against necrosis but not apoptosis by heat-stress proteins in vascular smooth muscle cells: evidence for distinct modes of cell death. (5/2283)

We have reported previously that cultured vascular smooth muscle cells (VSMC) isolated from spontaneously hypertensive rats (SHR) show higher proliferation and cell death than normotensive controls. In addition to protecting cells against death, heat stress proteins (HSPs) appear to play a role in cell proliferation. This investigation examines the involvement of HSP72 and HSP27 in altered SHR VSMC proliferation and death. We have performed detailed discriminatory analysis to characterize which type of VSMC death is induced by heat stress (HS) and serum deprivation. Serum deprivation induced apoptosis (caspase-3 cleavage and DNA laddering) and secondary necrosis, the 2 processes being a continuum of each other. In contrast, acute HS (46 degrees C, 30 minutes), which inhibited BN. lx and SHR VSMC proliferation by 2-fold, increased necrosis (by 5-fold and 2-fold, respectively) but not apoptosis. HSP72 and HSP27 expression evoked in VSMC by mild HS (44 degrees C, 15 minutes) 6 hours before acute HS prevented the inhibition of proliferation and induction of necrosis with no effect on serum deprivation-induced or staurosporine-induced apoptosis. This induced expression of HSP72 and HSP27 did not eliminate the higher basal proliferation, apoptosis, and necrosis of SHR VSMC compared with BN.lx VSMC, suggesting that these HSPs are not involved in altered SHR VSMC proliferation and death. Also, although apoptosis and necrosis may be a continuum, in VSMC the 2 processes may be distinguished by HS, in which only necrosis is prevented by prior HSP accumulation. This observation may be of use in designing strategies for cellular protection. (+info)

O-glycosylation potential of lepidopteran insect cell lines. (6/2283)

The enzyme activities involved in O-glycosylation have been studied in three insect cell lines, Spodoptera frugiperda (Sf-9), Mamestra brassicae (Mb) and Trichoplusia ni (Tn) cultured in two different serum-free media. The structural features of O-glycoproteins in these insect cells were investigated using a panel of lectins and the glycosyltransferase activities involved in O-glycan biosynthesis of insect cells were measured (i.e., UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase, UDP-Gal:core-1 beta1, 3-galactosyltransferase, CMP-NeuAc:Galbeta1-3GalNAc alpha2, 3-sialyltransferase, and UDP-Gal:Galbeta1-3GalNAc alpha1, 4-galactosyltransferase activities). First, we show that O-glycosylation potential depends on cell type. All three lepidopteran cell lines express GalNAcalpha-O-Ser/Thr antigen, which is recognized by soy bean agglutinin and reflects high UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase activity. Capillary electrophoresis and mass spectrometry studies revealed the presence of at least two different UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferases in these insect cells. Only some O-linked GalNAc residues are further processed by the addition of beta1,3-linked Gal residues to form T-antigen, as shown by the binding of peanut agglutinin. This reflects relative low levels of UDP-Gal:core-1 beta1,3-galactosyltransferase in insect cells, as compared to those observed in mammalian control cells. In addition, we detected strong binding of Bandeiraea simplicifolia lectin-I isolectin B4 to Mamestra brassicae endogenous glycoproteins, which suggests a high activity of a UDP-Gal:Galbeta1-3GalNAc alpha1, 4-galactosyltransferase. This explains the absence of PNA binding to Mamestra brassicae glycoproteins. Furthermore, our results substantiated that there is no sialyltransferase activity and, therefore, no terminal sialic acid production by these cell lines. Finally, we found that the culture medium influences the O-glycosylation potential of each cell line. (+info)

Flow cytometric cell cycle analysis of cultured porcine fetal fibroblast cells. (7/2283)

Normal development of nuclear transfer embryos is thought to be dependent on transferral of nuclei in G0 or G1 phases of the cell cycle. Therefore, we investigated the cell cycle characteristics of porcine fetal fibroblast cells cultured under a variety of cell cycle-arresting treatments. This was achieved by using flow cytometry to simultaneously measure cellular DNA and protein content, enabling the calculation of percentages of cells in G0, G1, S, and G2+M phases of the cell cycle. Cultures that were serum starved for 5 days contained higher (p < 0.05) percentages of G0+G1 (87.5 +/- 0. 7) and G0 cells alone (48.3 +/- 9.7) compared with rapidly cycling cultures (G0+G1: 74.1 +/- 3.0; G0: 2.8 +/- 1.2). Growth to confluency increased (p < 0.05) G0+G1 percentages (85.1 +/- 2.8) but did not increase G0 percentages (6.0 +/- 5.3) compared to those in cycling cultures. Separate assessment of small-, medium-, and large-sized cells showed that as the cell size decreased from large to small, percentages of cells in G0+G1 and G0 alone increased (p < 0.05). We found 95.2 +/- 0.3% and 72.2 +/- 12.0% of small serum-starved cells in G0+G1 and G0 alone, respectively. Cultures were also treated with cell cycle inhibitors. Treatment with dimethyl sulfoxide (1%) or colchicine (0.5 microM) increased percentages of cells in G0 (24.8 +/- 20.0) or G2+M (37.4 +/- 4.6), respectively. However, cells were only slightly responsive to mimosine treatment. A more complete understanding of the cell cycle of donor cells should lead to improvements in the efficiency of nuclear transfer procedures. (+info)

Cellular effects of beta-particle delivery on vascular smooth muscle cells and endothelial cells: a dose-response study. (8/2283)

BACKGROUND: Although endovascular radiotherapy inhibits neointimal hyperplasia, the exact cellular alterations induced by beta irradiation remain to be elucidated. METHODS AND RESULTS: We investigated in vitro the ability of 32P-labeled oligonucleotides to alter (1) proliferation of human and porcine vascular smooth muscle cells (VSMCs) and human coronary artery endothelial cells (ECs), (2) cell cycle progression, (3) cell viability and apoptosis, (4) cell migration, and (5) cell phenotype and morphological features. beta radiation significantly reduced proliferation of VSMCs (ED50 1.10 Gy) and ECs (ED50 2.15 Gy) in a dose-dependent manner. Exposure to beta emission interfered with cell cycle progression, with induction of G0/G1 arrest in VSMCs, without evidence of cell viability alteration, apoptosis, or ultrastructural changes. This strategy also proved to efficiently inhibit VSMC migration by 80% and induce contractile phenotype appearance, as shown by the predominance of alpha-actin immunostaining in beta-irradiated cells compared with control cells. CONCLUSIONS: 32P-labeled oligonucleotide was highly effective in inhibiting proliferation of both VSMCs and ECs in a dose-dependent fashion, with ECs showing a higher resistance to these effects. beta irradiation-induced G1 arrest was not associated with cytotoxicity and apoptosis, thus demonstrating a potent cytostatic effect of beta-based therapy. This effect, coupled to that on VSMC migration inhibition and the appearance of a contractile phenotype, reinforced the potential of ionizing radiation to prevent neointima formation after angioplasty.
