The tinman (tin) and bagpipe (bap) genes are members of the NK homeobox gene family of Drosophila, so that tin occupies a higher position than bap in the regulatory hierarchy. Little is known about the level and pattern of genetic polymorphism in homeobox genes. We have analyzed nucleotide polymorphism in 27 strains of Drosophila melanogaster and one each of D. simulans and D. sechellia, within...
A modifying influence of ortho-cresol (o-cresol) on the carcinogenic effect of benzo(a)pyrene (BaP) with combined oral administration to CC57Br mice had been found. During simultaneous administration of o-cresol (1 mg) and BaP (1 mg), the incidence of tumors, the multiplicity of tumors, and the degree of malignancy all increased, but the latency was shortened. When o-cresol was administered bef...
This experiment was conducted to investigate the effects of Bacillus amyloliquefaciens probiotic (BAP) as a direct-fed microbial on growth performance, cecal microflora, serum immunoglobulin levels, and fecal noxious gas emissions of broiler chickens. A total of 400 one-day-old broiler chicks (Ross 308) were randomly assigned to 1 of 5 treatment diets formulated to supply 0, 1, 5, 10, and 20 g/...
Knowledge of the ability of the female reproductive system to metabolize polycyclic aromatic hydrocarbons (PAHs) is critical to the diagnosis and management of female infertility and for risk assessment purposes. The PAHs are a family of widespread pollutants that are released into the environment from automobile exhausts, cigarette smoke, burning of refuse, industrial emissions, and hazardous ...
BACKGROUND Parents of children with autism have higher rates of broad autism phenotype (BAP) features than parents of typically developing children (TDC) in Western countries. This study was designed to examine the rate of BAP features in parents of children with autism and the relationship between parental BAP and the social impairment of their children in a Chinese sample. METHODS A total o...
Benzo(a)pyrene (BaP) is a ubiquitously distributed environmental pollutant. BaP is a known carcinogen and can induce malignant transformation of rodent and human cells. Many evidences suggest that inhibitor of poly(ADP-ribose) glycohydrolase (PARG) is potent anticancer drug candidate. However, the effect of PARG on BaP carcinogenesis remains unclear. We explored this question in a PARG-deficien...
The plant hormones cytokinins (CKs) regulate multiple developmental and physiological processes in Arabidopsis (Arabidopsis thaliana). Responses to CKs vary in different organs and tissues (e.g. the response to CKs has been shown to be opposite in shoot and root samples). However, the tissue-specific targets of CKs and the mechanisms underlying such specificity remain largely unclear. Here, we ...
Repeated cycles of vascular injury by benzo(a)pyrene (BaP) increase the onset and progression of atherosclerotic lesions in laboratory animals. This atherogenic response is partly mediated by activation of cis-acting antioxidant/electrophile response elements that enhance c-Ha-ras transcription in vascular smooth muscle cells (vSMCs). Activation of antioxidant/electrophile responsive cis-acting...
Many studies using mammalian cellular and subcellular systems have demonstrated that polycyclic aromatic hydrocarbons, including benzo[a]pyrene (BaP), are metabolically activated by cytochrome P450s (CYPs). In order to evaluate the role of hepatic versus extra-hepatic metabolism of BaP and its pharmacokinetics, we used the hepatic cytochrome P450 reductase null (HRN) mouse model, in which cytoc...
