The human preproapolipoprotein C-II gene. Complete nucleic acid sequence and genomic organization 总被引:4,自引:0,他引:4
The complete nucleic acid sequence of human preproapolipoprotein (apo) C-II has been determined from 2 apoC-II clones isolated from 2 different human genomic DNA libraries. The cloned fragments were approx. 14 and 18 kb long, and sequence analysis established that the apoC-II gene consists of 3338 nucleotides containing 3 intervening sequences of 2391, 167, and 298 bases. The first intron is located within the 5'-untranslated region of apoC-II and contains 4 Alu type sequences. The second intron interrupts the codon specifying amino acid - 11 of the apoC-II signal peptide. The last intron, which contains a 38 bp sequence which is repeated 6 times, interrupts the codon specifying for amino acid +44 of the mature apolipoprotein. 相似文献

Abstract. The holarctic ant tribe Formicini is revised, the new genus Bajcaridris described, and possible phylogenetic relationships are discussed. The subgenus Iberoformica is synonymized with Formica. A synopsis, diagnosis and keys to the genera are provided. 相似文献

Highlights? Drugs targeting the tumor vasculature are under investigation for cancer treatment ? However, changes in tumor vasculature may promote tumor growth and/or tumor spread ? Our analysis shows that sunitinib does not accelerate tumor growth in humans ? Sunitinib administration has positive effects and no negative effects when stopped 相似文献

Herbaspirillum seropedicae is an endophytic diazotroph associated with economically important crops such as rice, sugarcane, and wheat. Here, we present a 2-D reference map for H. seropedicae. Using MALDI-TOF-MS we identified 205 spots representing 173 different proteins with a calculated average of 1.18 proteins/gene. Seventeen hypothetical or conserved hypothetical ORFs were shown to code for true gene products. These data will support the genome annotation process and provide a basis on which to undertake comparative proteomic studies. 相似文献

本文报道海拔3417m和4280m地区世居藏族和移居汉族青少年运动状态下心肺功能的对比研究。结果显示:3417m和4280m世居藏族的最大氧耗量、无氧阈值及最大心输出量都明显大于汉族,血氧饱和度(Sao2)随运动负荷的增加而降低。海拔3417m藏、汉族的△Sao2分别为7.46%和10.03%,4280m处为8.57%和13.75%,最大心率随海拔升高而下降。研究提示,藏族青少年有较高的最大有氧能力,反映了他们对低氧环境的适应优势。 相似文献

Patients harboring germline mutations in the succinate dehydrogenase complex subunit B (SDHB) gene present with pheochromocytomas and paragangliomas (PPGL) that are more likely malignant and clinically aggressive. The combination chemotherapy cyclophosphamide, vincristine, and dacarbazine (CVD) was retrospectively evaluated in patients with SDHB-associated metastatic PPGL.Query Twelve metastatic PPGL patients harboring SDHB mutations/polymorphisms with undetectable SDHB immunostaining were treated with CVD. CVD therapy consisted of 750 mg/m2 cyclophosphamide with 1.4 mg/m2 vincristine on day 1 and 600 mg/m2 dacarbazine on days 1 and 2, every 21–28 days. Treatment outcome was determined by RECIST criteria as well as determination of response duration and progression-free and overall survivals. A median of 20.5 cycles (range 4–41) was administered. All patients had tumor reduction (12–100% by RECIST). Complete response was seen in two patients, while partial response was observed in 8. The median number of cycles to response was 5.5. Median duration of response was 478 days, with progression-free and overall survivals of 930 and 1190 days, respectively. Serial [18F]-fluorodeoxyglucose positron emission tomography and computed tomography imaging demonstrated continued incremental reduction in maximal standardized uptake values (SUVmax) values in 26/30 lesions. During treatment administration, the median SUV decreased from?> 25 to?< 6, indicating the efficacy of chemotherapy over a prolonged period of time. Prolonged therapy results in continued incremental tumor reduction, and is consistent with persistent drug sensitivity. CVD chemotherapy is recommended to be considered part of the initial management in patients with metastatic SDHB-related PPGL. 相似文献
