| contents | Cancer is a complex sequence of disease conditions progressing gradually with generalized loss of growth control. It continues to be one of the biggest global health problems, and its etiology has given rise to a huge array of treatment outside of conventional chemotherapy. Melanoma is one of the deadliest forms of skin cancer originating from melanocytes. It is characterized by the overproduction of melanin by the increased in cell proliferation. Melanogenesis, the production of melanin is by melanocyte-stimulating hormone (MSH) which stimulates cyclic AMP (cAMP) production to increase melanocyte production. Through the use of methylxanthines, theophylline proliferation rate can be decreased by increasing cell differentiation. One of the basic principles of cell biology is the selectivity of differentiation and proliferation, where cells usually grow or differentiate but not both. This study aimed to collect baseline data of untreated B16-F10 melanoma cells to determine morphology and doubling time of untreated cells. This data was further compared to results from varied concentration treatments of theophylline. It was hypothesized that increased levels in cyclic adenosine monophosphate (cAMP) could induce differentiation of melanocytes to terminate proliferation. To test this hypothesis, we collected a series of images of B16- F10 derived from mouse melanoma cells and seeded cells into a 12-well plate to calculate cell concentration for a five-day period and doubling time for untreated cells. Theophylline levels were varied to stimulate the production of cAMP and determine its effect on melanocyte proliferation and differentiation. The observed results showed that intracellular stabilization of cAMP, via phosphodiesterase inhibition by methylxanthines like theophylline, increases cell differentiation on melanoma cells and suppresses their growth. |
