Because vitamin A regulates epithelial cell differentiation and proliferation, there has been considerable interest in the apparent ability of retinol and related compounds to interfere with carcinogenesis. Vitamin A deficiency in humans enhances susceptibility to carcinogenesis.

Why is Cd the species of the metal that is noxious to organisms, toxic Cellular concentrations of essential metal ions are tightly regulated and both deficiency and overload have adverse effects. Non-essential metal ions, such as Cd ", compete with essential metal ions for entry into cells. Their interference with the function of essential metal ions dismpts cellular functions and leads to disease. Moreover, iron and zinc deficiencies, which are both most common in humans, enhance Cd " uptake. 

Tin. The widespread use of caimed foods results in a daily intake of tin that is ca 1—17 mg for an adult male (154). At this level it has not been shown to be toxic. Some grains also contain tin. Too much tin can adversely affect 2inc balance and iron metaboHsm. EssentiaUty has not been confirmed for humans. It has been shown for the rat. An enhanced growth rate results from tin supplementation of low tin diets (85). Animals on deficient diets exhibit poor growth and decreased feed efficiency (155). 

Another member of the FGF family, FGF-4, protects against radiation-iaduced ceU killing and enhanced the G2 arrest when overexpressed ia a human adrenal cortical carcinoma ceU line (196). This effect is again manifested as the appearance of a shoulder on the survival curve, although neither the control nor the transfected cells undergo radiation-iaduced apoptosis. No differences ia the yield or repair of either SSBs or DSBs have been observed. 

Whereas epidermal growth factor (EGF) enhances the radiosensitivity of human squamous ceU carcinoma cells in vitro (197), addition of EGF to hormone-deprived MCE-7 breast cancer cells prior to irradiation results ia iacreased radioresistance (198). An anti-EGE-receptor monoclonal antibody blocks the abiUty of EGE to enhance growth and radioresistance. Tumor cells, the growth of which is stimulated by EGE, appear to be protected those where growth is iohibited are sensitized (198). 

A 2-h incubation with another PGE2 analogue, nocloprost (9P-chloro-DMPG) protects normal human fibroblasts but has no effect on the survival of colon adenocarcinoma cells exposed to 10 Gy (1000 rad) (218). Nocloprost protects against radiation-induced DSBs in normal cells but not in tumor cells. Moreover, incubation using nocloprost for 2 h after irradiation enhances the rate of DSB rejoining in fibroblasts but not in adenocarcinoma cells. These data possibly reflect a different distribution of PG receptors on the plasma membrane of the two cell types. 

The recommended daily allowance for vitamin E ranges from 10 international units (1 lU = 1 mg all-rac-prevent vitamin E deficiency in humans. High levels enhance immune responses in both animals and humans. Requirements for animals vary from 3 USP units /kg diet for hamsters to 70 lU /kg diet for cats (13). The complete metaboHsm of vitamin E in animals or humans is not known. The primary excreted breakdown products of a-tocopherol in the body are gluconurides of tocopheronic acid (27) (Eig. 6). These are derived from the primary metaboUte a-tocopheryl quinone (9) (see Eig. 2) (44,45).
