Regulation Of Melanogenesis At The Sub-Cellular Level In Cloudman Murine Melanoma Cells, Kenneth Rosenzweig Apr 1992

Regulation Of Melanogenesis At The Sub-Cellular Level In Cloudman Murine Melanoma Cells, Kenneth Rosenzweig

Yale Medicine Thesis Digital Library

The decarboxylation of dopachrome to 5,6-dihydroxyindole (DHI) appears to be a major control point in the biosynthesis of melanin, in particular the conversation of dopachrome to 5,6-dihydroxyindole-2-carboxylic acid (DHICA). The recent discovery of a factor, DHICA stablin, that stabilizes DHICA and inhibits its conversion to DHI has added insight into the regulation of this intermediary compound. This study has shown that DHICA stablin activity is present in the melanosomal fraction of Cloudman murine melanoma cells and that this activity was observed by a new method using two complementary decarboxylase assays. When three known decarboxylase stabilizing cofactors (biotin, pyridoxal phosphate, and …


T-Cell Tumor Prevention By Treatments With Psoralen/Uva-Inactivated Tumor Cells, Francis M. Lobo Apr 1992

In the photopheresis therapy for cutaneous T-cell lymphoma, malignant T-cells exposed to 8-methoxypsoralen (8-MOP) activated by ultraviolet A (UVA) light appear to induce an immunologic response against the malignancy. In order to investigate this response, we used T-cell hybridoma 2B4.11 in genetically compatible (AKR X B10 .A) F1 hybrid mice as a murine model for T-cell lymphoma. We compared the ability of cells inactivated by 8-MOP/UVA, mitomycin C (MMC)3 glutaraldehyde, and X-irradiation to immunize against tumor.

[3H]-thymidine-uptake assays determined the doses of 8-MOP/UVA, MMC, glutaraldehyde, and X-irradiation necessary for inactivation of 2B4.11 cells. Mice then were subjected to an immunization …


Cross-Cultural Association Between Dietary Animal Protein And Hip Fracture: An Hypothesis, Benjamin Jac Abelow Jan 1992

Cross-Cultural Association Between Dietary Animal Protein And Hip Fracture: An Hypothesis, Benjamin Jac Abelow

Yale Medicine Thesis Digital Library

Age-adjusted female hip fracture incidence has been noted to be higher in industrialized countries than non-industrialized countries. A possible explanation which has received little attention is that elevated metabolic acid production associated with a high animal protein diet might lead to chronic bone buffering and bone dissolution. In an attempt to examine this hypothesis, cross-cultural variations in animal protein consumption and hip fracture incidence were studied. When female fracture rates derived from 34 published studies in 16 countries were regressed against estimates of dietary animal protein, a strong, positive association was found. This association could not plausibly be explained by …


Characterization Of Pregnancy Induced Changes In Glucose Metabolism, Stacey Ann Berg Jan 1992

Characterization Of Pregnancy Induced Changes In Glucose Metabolism, Stacey Ann Berg

Yale Medicine Thesis Digital Library

Many reports indicate that pregnancy is a diabetogenic state in which there is both insulin resistance and an exaggerated maternal glucose and insulin response to food ingestion. However, the magnitude of these aberrations and their temporal relationship have not been adequately characterized. This study utilizes the hyperglycemic clamp technique to investigate the insulin secretory response and tissue sensitivity to insulin under hyperglycemic conditions in normal and gestational diabetic pregnancies. Our results indicate that third trimester normal pregnancy is characterized by an increased first phase (108.81+/-13.03 uU/ml) and second phase (228.57+/-43.40 microunits/ml) insulin secretory response as compared to non-pregnant controls (72.93+/-15.76, …
