Multivesicular bodies are endocytic compartments containing multiple small vesicles that originate from the invagination and 'pinching off' of the limiting membrane into the luminal space [1] [2] [3]. The molecular mechanisms responsible for the formation of these compartments are unknown. In the human melanoma cell line Mel JuSo, newly synthesised major histocompatibility complex (MHC) class I...

Abstract A suitable nutrient supply, especially of vitamins, is very significant for the deep display inherent genetic properties microorganisms. Here, using chemically defined minimal medium (MM) yeast, nicotinamide and inositol were confirmed to be more beneficial performance two industrial baker's yeasts, a conventional high-sugar-tolerant strain. Increasing or proper levels could enhance bo...

Glyoxysome, endoplasmic reticulum, mitochondria, and proplastid fractions were isolated from endosperm of castor beans (Ricinus communis) germinated for 5 days at 30 C. Samples from sucrose density gradients were diluted with 0.15 m KCI and the membranes pelleted. Lipid extracts of these membranes were analyzed for phosphoglyceride, acyl lipid, and sterol content. The endoplasmic reticulum cont...

Human malignant gliomas are the most common type of primary brain tumor. Composed glial cells and their precursors, they aggressive highly invasive, leading to a poor prognosis. Due difficulty surgically removing tumors resistance treatments, novel therapeutic approaches needed improve patient life expectancy comfort. Drosophila melanogaster is compelling genetic model better understanding huma...
