damage proteins directly by the oxidation of SH groups. (For non-dividing cells, notably neurons, metabolic damage garbage accumulation could be anarchism and other essays analysis considered the "weakest link" if it weren't for the fact that cell death is so different from cell senescence.) Metabolic damage would be much less of a problem if its byproducts (cross-links, AGEs, lipofuscin. Of course, anorexics who are malnourished for micronutrients are not examples of human cran. The HSF1 transcription factor (Heat Shock Factor, which regulates heat shock response) has been shown to be essential for Daf16 induced longevity.elegans. Xeroderma pigmentosum ( XP ) patients show tissue-specific signs of premature aging, mainly of the skin eyes photoaging have a high incidence of skin cancer (more than a thousand-fold over normal) and have neurological problems.

DNA microarray analysis of salamanders has shown that humoral immune and local tissue factors control the initial phase of limb regeneration, but nerve-derived factors later become crucial BMC biology; Monaghan, JR; 7:1-19 (2009). Senescent cytotoxic T-cells have been removed from the serum of mice by attachment of iron oxide nanoparticles linked to antibodies and applying a magnetic field to the serum in an extracorporeal circuit rejuvenation research; Rebo, J; 13(2-3 298-300 (2010). In centenarians, however, no decline in NK activity has been seen nor was there a decline in youthful CD8/CD4 cells immunology today; Franceschi, C; 16(1 12-16 (1995). A study which correlated maximum lifespan in a variety of mammalian species found a six-fold difference in the nuclear DNA-repair activity of mice and men. There is a "family" of Bcl2 proteins, all of which possess at least one of four B cl2 H omology domains ( BH1 to BH4 ). The are quite a few studies indicating that Deprenyl, for example, has extended the maximum lifespan of a variety of mammals. The testes have been regarded as the source of maleness at least since ancient Rome, where eunuchs women were not permitted to "testify" ( testis is Latin for "witness. ROS attack bases in nucleic acids, amino acid side chains in proteins and double-bonds in unsaturated fatty acids with the hydroxyl radical being the strongest attacker. Cortisol can reduce neuron uptake of glucose by 15-25 which can contribute to neuron death experimental gerontology 34:721-732 (1999). (For more about mechanisms of apoptosis see Cellular Senescence and Apoptosis in Aging ) (return to contents).

A convincing case has been made that cran operates by evolutionarily-conserved mechanisms of nutrient-sensing molecular pathways (insulin/IGF-1) in yeast, worms, flies, and mammals  science; Fontana, L; 328:321-326 (2010). Despite resistance to both insulin IGF1, the mice have normal size food intake, but fertility is reduced science; Kurosu, H; 309: (2005). A similar study of 8 non-primate mammals showed a direct correlation between maximum lifespan and oxidative damage to mtDNA in heart brain. CoQ and then to CoQ. In apoptosis the mptp opens only briefly (if it opens at all whereas in necrosis the mptp remains open. Activation proliferation of muscle regenerating progenitor cells (satellite cells) is dependent upon signalling from transmembrane Notch receptors. Simplistically, FSH stimulates egg production in females sperm production in males, whereas LH stimulates estrogen production in females testosterone production in males. Accumulated free radical, glycation and other forms of cellular damage lead increasingly to dysfuncional cell-cycle control with age.
