The in vitro radiosensitivity of one murine melanoma cell line (Cloudman S91 CCL 53.1) and three human melanoma cell strains (C8146C, C8161, and R83-4) were studied. Cells were irradiated by single dose X-rays and plated either in agar or on plastic.

Five human melanoma cell lines (C8146C, C8161, C82-7A, C83-2CY and MIRW5) were shown to contain a significant number of melanoma colony-forming units resistant to single-agent treatment by dexamethasone, alpha-interferon and trans-retinoic acid. Thes

Adenosine inhibits S-91 melanoma membrane adenylate cyclase. This inhibition is observed with all activators tested; α-melanocyte-stimulating hormone, [norleucine 4 ]α-melanocyte-stimulating hormone, prostaglandin-E 2 , and fluoride ion. This inhib

The ability of difluoromethylornithine (DFMO), a specific polyamine synthesis inhibitor, to interact with various biological modifiers to inhibit the colony-forming growth of human melanoma cells was determined by using the median effect principle to

Contrary to other published reports, iodinated β-melanocyte stimulating hormone (β-MSH) is without biological activity as measured by frog skin bioassay, melanoma (mouse S-91) adenylate cyclase assay, or melanoma tyrosinase assay. Inactivation resu

The reaction of glucagon with 4-fluoro-3-nitrophenylazide has been shown to afford the photosensitive derivative, Nϵ-4-azido-2-nitrophenyl-glucagon. The structure and properties of this derivative were established by amino acid analysis, absorption

(Des-Histidine 1 ) (N ϵ -phenylthiocarbamoyllysine 12 )-glucagon, synthesized by the one-step Edman degradation procedure is a competitive inhibitor of glucagon action in the rat liver plasma membrane adenylate cyclase system. However, in the perfus

The inhibitory effect of various prostaglandin analogues on the anchorage independent growth of murine and human melanoma cells was measured. PGA analogues (which were modified at C-16 and C-18) did not demonstrate any major improvement in activity o

We measured the effect that staining with 2-(P-iodophenyl)-3-(p-nitrophenyl)-5-phenyl tetrazolium chloride (INT) had on the number and size distribution of tumor colonies counted using an optical image analyzer (FAS II). Staining increased the number

The radiation response of murine and human melanoma cells assayed in bilayer soft agar and monolayer was examined. Cells from the murine melanoma Cloudman S91 CCL 53.1 cell line and three human melanoma cell strains (C8146C, C8161, and R83-4) develop
