A reassessment of methylcholanthrene transformation in the C3H10T1/2 cell culture system (1990)

Chen, Anne C., Brankow, David W., Herschman, Harvey R.

We previously demonstrated that four tumorigenic methylcholanthrene (MCA) transformed cell lines derived from C3H10T1/2 cells each contain a common G34 – T nucleotide alteration in the c-Ki-ras...

The tumor promoters 12-O-tetradecanoylphorbol-13-acetate and okadaic acid differ in toxicity, mitogenic activity and induction of gene expression (1989)

Herschman, Harvey R., Lim, Robert W., Brankow, David W., Fujiki, Hirota

Okadaic acid (OA) and 12-O-tetradecanoylphorbol-13-acetate (TPA) are both potent tumor promoters in a mouse skin carcinogenesis experiment. OA was much more toxic than TPA for murine embryo cell...

A continuum of transformed phenotypes in C3H/10T1/2 derivatives (1988)

Chen, Anne C., Herschman, Harvey R.

Two-stage transformants have been isolated from C3H/10T1/2 cells exposed to UV-irradiation followed by treatment with TPA. These UV-TDTx cells form foci in co-culture with C3H/10T1/2...

Colony size, cell density and nature of the tumor promoter are critical variables in expression of a transformed phenotype (focus formation) in co-cultures of UV-TDTx and C3H10T1/2 cells (1987)

Herschman, Harvey R., Brankow, David W.

UV-TDTx cells are cloned from foci arising after C3H10T1/2 cells are sequentially exposed to u.v. irradiation followed by tetradecanoylphorbol acetate (TPA). When grown in pure culture, UV-TDTx...

Regulation of the rat metallothionein-I gene by sodium butyrate (1986)

Birren, Bruce W., Herschman, Harvey R.

Sodium butyrate selectively induces accumulation of metallothionein-I (MT-I) RNA in H4IIE rat hepatoma cells. The induction 1s rapid; significant elevation in cytoplasnric MT-I RNA can be observed...

Teleocidin is not mitogenic for 12-O-tetradecanoylphorbol-13-acetate non-proliferative variants of 3T3 cells (1983)

Herschman, Harvey R.

Teleocidin and 12-O-tetradecanoylphorbol-acetate (TPA), two potent tumor promoters, are also excellent mitogens for 3T3 cells. I now demonstrate that teleocidin is unable stimulate mitogenesis in TPA...

A mutant herpes simplex virus type 1 thymidine kinase reporter gene shows improved sensitivity for imaging reporter gene expression with positron emission tomography

Gambhir, Sanjiv S., Bauer, Eileen, Black, Margaret E., Liang, Qianwa, Kokoris, Mark S., Barrio, Jorge R., ...

We are developing assays for noninvasive, quantitative imaging of reporter genes with positron emission tomography (PET), for application both in animal models and in human gene therapy. We report...

Functional and Biochemical Analysis of the C2 Domains of Synaptotagmin IV

Thomas, David M., Ferguson, Gregory D., Herschman, Harvey R., Elferink, Lisa A.

Synaptotagmins (Syts) are a family of vesicle proteins that have been implicated in both regulated neurosecretion and general membrane trafficking. Calcium-dependent interactions mediated through...

Deficits in memory and motor performance in synaptotagmin IV mutant mice

Ferguson, Gregory D., Anagnostaras, Stephan G., Silva, Alcino J., Herschman, Harvey R.

Synaptotagmin (Syt) IV is a synaptic vesicle protein. Syt IV expression is induced in the rat hippocampus after systemic kainic acid treatment. To examine the functional role of this protein in vivo,...

Imaging adenoviral-directed reporter gene expression in living animals with positron emission tomography

Gambhir, Sanjiv S., Barrio, Jorge R., Phelps, Michael E., Iyer, Meera, Namavari, Mohammad, Satyamurthy, Nagichettiar, ...

We are developing quantitative assays to repeatedly and noninvasively image expression of reporter genes in living animals, using positron emission tomography (PET). We synthesized positron-emitting...

Comparative Study of the Events Associated with Colicin Induction

Herschman, Harvey R., Helinski, Donald R.

Colicinogenic factors ColI and ColV, which have been shown to behave as sex factors, could not be induced with mitomycin C. In contrast, the ColE1, ColE2, and ColE3 factors, which do not exhibit any...

Effect of Rec− Mutations on the Activity of Colicinogenic Factors

Helinski, Donald R., Herschman, Harvey R.

The effect of two Rec− mutations (AB2463 and JC1553) on the ability of a cell to accept, maintain, and express the colicinogenic factors ColE1, ColE2, and ColV was examined in Escherichia coli....

Modulation of Cell-Surface Antigens of a Murine Neuroblastoma

Akeson, Richard, Herschman, Harvey R.

Antisera were produced in rabbits to morphologically differentiated cells from the C1300 murine neuroblastoma (i.e., cells in which process formation was induced by maintenance on serum-free medium...
