Includes fatty acids; neutral fats, other fatty-acid esters, and soaps; long-chain (fatty) alcohols and waxes; sphingoids and other long-chain bases; glycolipids, phospholipids and sphingolipids; and carotenes, polyprenols, sterols, terpenes and other isoprenoids [goid 6629] [pmid 11839751] [evidence TAS]; The chemical reactions and pathways involving fatty acids, aliphatic monocarboxylic acids liberated from naturally occurring fats and oils by hydrolysis [goid 6631] [pmid 9177185] [evidence TAS]; A process that directly activates any of the steps required for cell death by apoptosis [goid 6917] [pmid 11839751] [evidence TAS]; Any process that stops, prevents or reduces the rate or extent of cell proliferation [goid 8285] [evidence ISS]; Any process that stops, prevents or reduces the rate or extent of cell proliferation [goid 8285] [pmid 11839751] [evidence IDA]; The chemical reactions and pathways resulting in the formation of leukotriene, a pharmacologically active substance derived from a polyunsaturated fatty acid, such as arachidonic acid [goid 19370] [evidence IEA]; Any process that stops, prevents or reduces the frequency, rate or extent of cell migration [goid 30336] [pmid 11839751] [evidence TAS]; The process whose specific outcome is the progression of the prostate gland over time, from its formation to the mature structure. The prostate gland is a partly muscular, partly glandular body that is situated near the base of the mammalian male urethra and secretes an alkaline viscid fluid which is a major constituent of the ejaculatory fluid [goid 30850] [pmid 11839751] [evidence NAS]; Any process that modulates the frequency, rate or extent of epithelial cell differentiation [goid 30856] [pmid 11839751] [evidence NAS]; Any process that stops, prevents or reduces the rate or extent of progression through the cell cycle [goid 45786] [pmid 11839751] [evidence IDA]; Any process that stops, prevents or reduces the rate or extent of progression through the cell cycle [goid 45786] [evidence ISS]; Any process that stops, prevents or reduces the rate or extent of growth, the increase in size or mass of all or part of an organism [goid 45926] [pmid 11839751] [evidence IDA]; Any process that stops, prevents or reduces the rate or extent of growth, the increase in size or mass of all or part of an organism [goid 45926] [evidence ISS]; The process of removal or addition of one or more electrons with or without the concomitant removal or addition of a proton or protons [goid 55114] [evidence IEA]
