In the design of sequential high-dose chemotherapy regimens, the selection of antitumor alkylating agents to be included in each intensification and the interval between the intensifications are critical to the design of the therapy. The tumor cell s

The gene for transforming growth factor-beta 1 (TGF-beta 1) was transfected into the murine EMT-6/Parent mammary carcinoma tumor line to form the EMT6/PRK5 beta 1E tumor line. In monolayer culture the EMT-6/PRK5 beta 1E tumor line secretes about 15-t

Transforming growth factor-beta (TGF-beta) has been implicated in the in vivo resistance of the EMT-6/CTX and EMT-6/ CDDP murine mammary tumors. Both of these tumors have a higher number of intratumoral vessels than the EMT-6/ parent tumor. Animals b

Lisofylline is a new methylxanthine. The potential of lisofylline to enhance the response to ionizing radiation of the EMT-6 murine mammary carcinoma in vitro and in vivo was assessed and compared with pentoxifylline. Addition of lisofylline (100 mic

Further evidence for organelle interaction during drug metabolism by the liver is presented. The apparent stimulation by succinate of formaldehyde accumulation in the medium, which was reported to occur with liver slices and homogenates as well as wi

A pH difference (acid inside) across the platelet plasma membrane increases both the rate and extent of serotonin accumulation inside plasma membrane vesicles. Even in the absence of other transmembrane ion gradients, this pH difference (delta pH) se

The oxidation of formaldehyde by rat liver mitochondria in the presence of 50 mM phosphate was enhanced 2-fold by exogenous NAD+. Absolute requirement of NAD+ for formaldehyde oxidation was demonstrated by depleting the mitochondria of their NAD+ con

Aerobic and hypoxic cultures of EMT6 mouse mammary tumor cells were used to study the effects of dicoumarol (DIC) on the cytotoxicity of mitomycin C (MC). DIC protected aerobic cells from MC toxicity, but sensitized hypoxic cells to the cytotoxic act

We have demonstrated previously that dicoumarol (DIC) increased the generation of reactive metabolites from mitomycin C (MC) in EMT6 cells under hypoxic conditions in vitro. This increased reaction rate was associated with an increased toxicity of MC
