真菌基因组较其他真核生物基因组结构简单,长度短,易于测序、组装与注释,因此真菌基因组是研究真核生物基因组的模型。为研究真菌基因组组装策略,本研究基于Illumina HiSeq测序平台对烟曲霉菌株An16007基因组测序,分别使用5种de novo组装软件ABySS、SOAP-denovo、Velvet、MaSuRCA和IDBA-UD组装基因组,然后通过Augustus软件进行基因预测,BUSCO软件评估组装结果。研究发现,5种组装软件对基因组组装结果不同,ABySS组装的基因组较其他4种组装软件具有更高的完整性和准确性,且预测的基因数量较高,因此,ABySS更适合本研究基因组的组装。本研究提供了真菌de novo测序、组装及组装质量评估的技术流程,为基因组<100 Mb的真菌或其他生物基因组的研究提供参考。 相似文献

Undernutrition during pregnancy and/or lactation plays an important role on the overall health of offspring later in life. Using a rodent model, the present study was conducted to examine the effect of fetal and early postnatal iron deficiency on iron metabolism in adult animals. Rats were treated with three stages of low or normal iron diets from gestation until the end of the study. During the first stage (4?weeks prior to 3?weeks after pregnancy, total 7?weeks), two groups of adult females (dams) were fed with either a low-iron (7.4?mg iron/kg, group LD) or control-iron (274?mg/kg, group CD) diet. During the second stage (from 3 to 13?weeks of age, total 10?weeks), all pups from stage 1 (both the LD and CD groups) were placed on a control-iron diet for 10?weeks (groups LD?CCD and CD?CCD, respectively). During the third stage (from 13 to 29?weeks of age, total 16?weeks), both LD?CCD and CD?CCD groups from stage 2 were fed with a low-iron (named LD?CCD?CLD and CD?CCD?CLD groups, respectively). We found that the live birth rate of the offspring of the LD dams (84.7?%) was significantly lower than that of the CD dams (95.4?%). During stage 2, the mean body weight of the LD?CCD male or LD?CCD female rats exceeded the CD?CCD male rats (p?<?0.05). Compared with the CD?CCD?CLD rats, the LD?CCD?CLD rats had significantly increased total iron binding capacity, and higher levels of transferrin, serum erythropoietin (EPO), renal EPO mRNA, duodenal divalent metal transporter-1, and renal transferrin receptors. These findings indicate that rats with an early-life experience of iron deficiency (during pregnancy and the nursing period) can develop stronger iron absorption capabilities in adulthood. 相似文献

Apoptosis is an essential process for the maintenance of liver physiology. The ability to noninvasively image apoptosis in livers would provide unique insights into its role in liver disease processes. In the present work, we established a stable mouse model by hydrodynamics methods to study the activity of caspase-3 and evaluate the effect of the apoptosis inhibitors in mouse livers under true physiological conditions by bioluminescence imaging. The reporter plasmid attB-ANLuc(DEVD)BCLuc that contains fragment of attB and ANLuc(DEVD)BCLuc was codelivered with the mouse-codon optimized φC31 (φC31o) integrase plasmids specifically to mouse liver by hydrodynamic injection procedure. Then, φC31o integrase mediated intramolecular recombination between wild-type attB and attP site in mice, and thus the reporter expression cassette attB-ANLuc(DEVD)BCLuc was integrated permanently into mouse liver chromosome. We used these mice to characterize in vivo activation of caspase-3 upon treatment with LPS/d-GalN. Our data show that liver apoptosis could be reflected by the activity of luciferase. The shRNA targeting caspase-3 protein or apoptosis inhibitors could effectively downregulate luciferase activity in vivo. Also, this model could be used to measure caspase-3 activation during inflammatory and infectious events in vivo as verified by infected with MHV-3. This model could be used for screening anti-apoptosis compounds target mouse livers. 相似文献

Recent progress in chimeric antigen receptor-modified T-cell(CAR-T cell) technology in cancer therapy is extremely promising, especially in the treatment of patients with B-cell acute lymphoblastic leukemia. In contrast, due to the hostile immunosuppressive microenvironment of a solid tumor, CAR T-cell accessibility and survival continue to pose a considerable challenge, which leads to their limited therapeutic efficacy. In this study, we constructed two anti-MUC1 CAR-T cell lines. One set of CAR-T cells contained SM3 single chain variable fragment(sc Fv) sequence specifically targeting the MUC1 antigen and co-expressing interleukin(IL) 12(named SM3-CAR). The other CAR-T cell line carried the SM3 sc Fv sequence modified to improve its binding to MUC1 antigen(named p SM3-CAR) but did not co-express IL-12. When those two types of CAR-T cells were injected intratumorally into two independent metastatic lesions of the same MUC1+ seminal vesicle cancer patient as part of an interventional treatment strategy, the initial results indicated no side-effects of the MUC1 targeting CAR-T cell approach, and patient serum cytokines responses were positive. Further evaluation showed that p SM3-CAR effectively caused tumor necrosis, providing new options for improved CAR-T therapy in solid tumors. 相似文献
