Abstract
A farnesyl diphosphate synthase (FPS) cDNA and promoter region was cloned from Sanghuangporus baumii. The gene contains a 150-bp 5'-untranslated region (UTR), a 154-bp 3'-UTR, and a 1062-bp open reading frame (ORF) encoding a 354 amino acid polypeptide. The FPS-DNA includes three exons (nucleotides 1 -123, 184-321, and 505-1305) and two introns (nucleotides 124-183 and 322-504). The FPS protein has a molecular weight of 40.73 kDa, it is hydrophilic with a theoretical isoelectric point of 5.13, and the secondary and three-dimensional structure were analysed. There is a transcription start site at nucleotides 1318-1368 of the promoter, which includes typical eukaryotic promoter elements (TATA Box, CAAT Box, ARBE, AT-rich element, G-box, MBS, Sp1, LTR). FPS was expressed in Escherichia coli BL21, and the recombinant protein (63.41 kDa) was subjected to dodecyl sulphate, sodium salt-polyacrylamide gel electrophoresis (SDS-PAGE). FPS transcription was measured during different developmental stages, and expression in 11 and 13 days mycelia was upregulated 49.3-fold and 125.4-fold, respectively, compared with 9 days mycelia controls. Through analysing, S. baumii triterpenoid content was correlated with the transcription level of FPS during different development stages, and the triterpenoid content peaked at day 15 (7.21 mg/g).

Abstract
Acetyl-CoA C-acetyltransferase synthase gene (AACT) cDNA, DNA and promoter were cloned from Sanghuangporus baumii. The gene ORF (1260 bp) encoded 419 amino acids. The AACT DNA includes five exons (1-84 bp, 140-513 bp, 570-1027 bp, 1090-1282 bp, 1344-1494 bp) and four introns (85-139 bp, 514-569 bp, 1028-1089 bp, 1283-1343 bp). The molecular weight of AACT protein is 43.40 kDa, it is hydrophilic with a theoretical isoelectric point of 8.96. Furthermore, The region of the transcription start site is 1997-2047 bp of AACT promoter, and it contained promoter elements (TATA Boxs, CAAT Boxs, CAAT-box, ABRE, G-Boxs, Sp1, MSA-like, LTR). AACT recombinant protein (43.40 KDa + Tag protein 22.68 KDa) was subjected in SDS-PAGE. AACT the transcription levels of in different development stages were investigated. The expression of AACT in primordia (2.4-fold) and 15 d mycelia (2.3- fold) were significantly higher than 9 d mycelia (contral). The expression level of the AACT downstream genes and triterpenoids content were determined at different developmental stages. Triterpenoid content reached its peak on day 15(7.21 mg/g).

Abstract
INTRODUCTION The aim of this study was to investigate whether estradiol (E2), E2 combined with progesterone (Prog) (E2/Prog), and genistein (Gen) treatment had antioxidative and anti-hyperlipidemic effects in the plasma of ovariectomized (OVX) rats. MATERIALS AND METHODS Adult female Sprague-Dawley rats were divided into five groups. Rats in all groups, except for those in a sham group, underwent bilateral ovariectomy under general anesthesia. The groups were as follows: sham group; control OVX group; group treated with estrogen (0.014 mg/kg 17-β E2); group treated with a combination of E2 and Prog (0.014 mg/kg 17-β E2 plus 0.028 mg/kg drospirenone), and group treated with Gen (10 mg/kg/day). Plasma of rats of each treatment group was analyzed to determine the total antioxidant status, total oxidant status, paraoxonase activity, lipid profile, high-density lipoprotein (HDL-chol), low-density lipoprotein (LDL-chol), total cholesterol (Total-C), triacylglycerols, lipoprotein (a), and oxidative stress index. RESULTS Plasma Total-C levels and body weight increased in all the OVX groups compared with the sham group (P<0.005). The group treated with E2 had significantly elevated total oxidant status, oxidative stress index, LDL-chol, and Total-C compared with the control group (P<0.005). Gen treatment might lead to lower LDL-chol and Total-C levels compared with E2 treatment. CONCLUSIONS Gen treatment might be preferred to E2 treatment for treatment of menopausal symptoms in patients at risk for cardiovascular diseases. However, considering the small sample size of this study, larger studies are needed in this area.
