Dissociation of increased hexose transport from initiation of fibroblast proliferation
Nature, 1974ALTERATIONS in the permeability of the surface membrane might play a key role in the control of DNA synthesis and cell division1–3. Evidence that changes in hexose transport might participate in growth control comes from reports that uptake of certain hexoses (1) increases after transformation by tumour viruses4–6, and correlates with the expression of

Antiviral and antiproliferative effects of interferons in quiescent fibroblasts are dissociable
Virology, 1985Quiescent mouse Swiss 3T3 cells or human fibroblasts treated with interferon for only 2 hr before the addition of serum are effectively protected against virus infection for up to 24 hr after the addition of serum and the removal of interferon. In sharp contrast, exposure of quiescent fibroblasts to interferon only before addition of serum or the ...

Dissociation of cell motility from cell proliferation in BALB/c-3T3 fibroblasts
Experimental Cell Research, 1972Abstract BALB/c-3T3 cells planted sparsely in a factor-free medium lacking serum growth factor(s) have substantial motility, yet few synthesize DNA or proliferate. Although these cells move rapidly in factor-free medium, the addition of dialysed serum further increased their motility demonstrating that they require a macromolecular serum factor(s ...

Dissociation of proto‐oncogene induction from growth response in normal human fibroblasts
Journal of Cellular Physiology, 1990AbstractProto‐oncogenes are cellular homologues of viral oncogenes that are known to be associated with regulation of growth and differentiation. The c‐myc and c‐fos proto‐oncogenes have been extensively studied by using established cell lines but to a lesser extent by using normal cells.

We investigated conditions for selective solubilization of the intermediate filament (IF) of BHK-21 cells, and found that a cationic detergent, cetyltrimethylammonium bromide (CTAB), was effective for rapid dissociation of IF into the monomeric form. More selective dissociation was performed with a combination of CTAB and Tween 40. The CTAB-dissociated

Rat embryonic fibroblasts growing exponentially at either 35, 37, or 39 degrees C were exposed to 42 degrees C for times up to 6 hr. Cell survival was unaffected by this heat shock in cultures growing at 39 degrees C but survival was decreased in a temperature dependent manner in cells growing at 37 or 35 degrees C.

We have studied the rate and character with which testosterone (T) and 5 alpha-dihydrotestosterone (DHT) dissociate from the androgen receptor both within intact cultured genital skin fibroblasts of a subject with 5 alpha-reductase deficiency and after the androgen-receptor complexes have been extracted from the cells. Within the cells, the kinetics of

The accumulation of [3H]inositol by mechanically dissociated brain cells and cultured skin fibroblasts from fetal mice was examined. Uptake by both tissues was strongly dependent on temperature and the presence of sodium ions. Brain and fibroblast uptake also responded similarly to inhibition by inositol isomers and phloridzin.

AbstractProtein profiles of skin fibroblasts labelled with [35S]‐methionine from patients with Duchenne muscular dystrophy (DMD) have been compared with those of cells from normal individuals by isoelectric focusing on thin polyacrylamide gels containing denaturing and solubilising agents cast on silanized supports.

Abstract A strain of human embryonic fibroblasts (HEB) was compared with the same cells transformed by RSV(HEB-SR) regarding growth curve, DNA synthesis between the time of seeding and the time growth stops, and nuclear overlapping in resting cultures.
