The photochemical activities of chloroplasts isolated from bundle sheath and mesophyll cells of maize (Zea mays var. DS606A) have been measured. Bundle sheath chloroplasts are almost devoid of grana, except in very young leaves, while mesophyll chloroplasts contain grana at all stages of leaf
In the present study, we investigated the effects of high levels of dietary fish oil on the growth of MX-1 human mammary carcinoma and its response to mitomycin C (MC) treatment in athymic mice. We found that high levels of dietary fish oil (20% menhaden oil + 5% corn oil, w/w) compared to a control
beta-Naphthoflavone (beta-NF) is a widely used inducer of phase-I and phase-II enzymes controlled by aryl hydrocarbon receptor (AhR). Studies of competitive binding with (3)H-labelled 2,3,7, 8-tetrachlorodibenzo-p-dioxin (TCDD), 3-methylcholanthrene (3-MC) and benzo[a]pyrene (B[a]P) have shown that
OBJECTIVE
Regulation of blood flow and oxygen supply are important pathogenetic factors in alcoholic liver disease. Because nitric oxide may have an important role, its effects on alcoholic liver injury were investigated.
METHODS
Rats were fed ethanol intragastrically with either saturated fat or
In higher plants ferredoxin (Fd):NADP(+) oxidoreductase (FNR) and Fd are each distributed in photosynthetic and non-photosynthetic organs as distinct isoproteins. We have cloned cDNAs for leaf FNR (L-FNR I and L-FNR II) and root FNR (R-FNR) from maize (Zea mays L.), and produced recombinant L-FNR I
The effects of decenylsuccinic acid on the swelling and respiratory capacities of mitochondria isolated from etiolated corn (Zea mays L., Wf9 x M14) shoots were studied. Decenylsuccinic acid (0.1 mM to 1.0 mM) inhibited the oxidation of succinate and malate-pyruvate, stimulated the oxidation of
In the present study, we investigated the effects of high dietary fat on the growth of MX-1 heterotransplanted in athymic mice and its response to mitomycin C (MC) treatment. We found that high fat intake (25% corn oil, w/w) significantly increased tumor growth, but at the same time it also
