Inhibitors, Agonists, Screening Libraries Data SheetBIOLOGICAL ACTIVITY:Ganetespib is a unique non–geldanamycin heat shock protein 90 (HSP90) inhibitor, with IC 50 of 4 nM in OSA 8 cells.In Vitro: Ganetespib causes depletion of receptor tyrosine kinases, extinguishing of downstream signaling, inhibition of proliferation and induction of apoptosis with IC 50 values ranging 2–30 nM in genomically–defined NSCLC cell lines. Ganetespib is alsoapproximately 20–fold more potent in isogenic Ba/F3 pro–B cells rendered IL–3 independent by expression of EGFR and ERBB2mutants [1]. Ganetespib exhibits potent in vitro cytotoxicity in a range of solid and hematologic tumor cell lines, induces the degradation of known Hsp90 client proteins, displays superior potency to the ansamycin inhibitor17–allylamino–17–demethoxygeldanamycin (17–AAG)[2]. Ganetespib is a potent HSP90 inhibitor, and shown to kill canine tumor cell lines in vitro [3]. Ganetespib possesses superior JAK/STAT inhibitory activity to both P6 and 17–AAG in terms of potency or duration of response in the HEL92.1.7 cells [4].In Vivo: Ganetespib (125 mg/kg, i.v.) accumulates in tumors relative to normal tissues and displays greater in vivo efficacy than 17–AAG without increased toxicity and inhibits proliferation and induces apoptosis in parallel with EGFR depletion in NCI–H1975xenografts [1]. Ganetespib (100, 125, 150 mg/kg, i.v.) shows potent antitumor efficacy in solid and hematologic xenograft models ofoncogene addiction, as evidenced by significant growth inhibition and/or regressions [2].PROTOCOL (Extracted from published papers and Only for reference)Kinase Assay:[1]Exponentially growing cells are processed in lysis buffer (20 mM HEPES, pH 7.4, 1 mM EDTA, 5 mM MgCl 2, 100 mM KCl) and incubated with increasing concentrations of 17–AAG or ganetespib for 30 min at 4°C, and incubated with biotin–GM linked to Dynabeads MyOne Streptavidin T1 magnetic beads for 1 h at 4°C. Beads are washed three times in lysis buffer and heated for 5 min at 95°C in SDS–PAGE sample buffer. Samples are resolved on 4–12% Bis–Tris gradient gel and Western blots are performed using an anti–HSP90 antibody.Cell Assay:[2]Cells are grown in 96–well plates based on optimal growth rates determined empirically for each line. Twenty–four hours after plating, cells are treated with the indicated compounds or controls for 72 hours. AlamarBlue is added (10% v/v) to the cells, and the plates are incubated for 3 hours and, then, subjected to fluorescence detection. For the comparative viability/apoptosis assay,NCI–H1975 cells are treated with escalating concentrations of ganetespib for the indicated time periods and subjected to viability analysis via CellTiter Fluor and apoptosis via Caspase Glo 3/7.Animal Administration: Ganetespib is formulated in 10/18 DRD (10% DMSO, 18% Cremophor RH 40, 3.6% dextrose and68.4% water).[1]NCI–H1975 or HCC827 cells are cultured as above and 0.5–1×107 cells are mixed with 50% RPMI 1640/50%Matrigel and subcutaneously injected into the flanks of SCID mice. For efficacy studies, animals with 100–200 mm 3 tumors are then randomized into treatments groups of eight. Tumor volumes (V) are calculated by the equation V=0.5236×L×W×T (Length, width, and thickness). Animals are treated by intravenous bolus tail vein injection at 10 mL/kg with ganetespib formulated in 10/18 DRD (10%DMSO, 18% Cremophor RH 40, 3.6% dextrose and 68.4% water). As a measurement of in vivo efficacy, the relative size of treated andProduct Name:Ganetespib Cat.

Body weights are monitored daily. For biomarker studies, mice bearing NCI–H1975 xenografts are treated with either a single dose of vehicle or ganetespib, or with 5 daily doses of vehicle or ganetespib, in groups of 3 or 8, and harvested at various time points. Tumors are excised and flash frozen in liquid nitrogen for preparation of protein lysates or fixed in 10% neutral buffered formalin for immunohistochemistry.References:[1]. Shimamura T, et al.

The medium pressure is continuously reduced along the sealing surface.A minimum amount of high pressure leakage serving as lubricant is returned to the pump suction chamber.Exclusive sealing systemThe plunger connection to thepower end is self centering thereby drastically reducing sideways forces. This design ensures that there is virtually no contact between the plunger and the labyrinth insert resulting in extremely low component wear.When the pump unit is shut down the medium remains in thecylindrical gap so that a re-start,even after an extended shut down period is assured.Wear at the high pressure seal components does not lead to an abrupt breakdown of the pump but rather a gradual decrease in the flow rate. If the pump is driven in a control loop the r.p.m. of the driver will increase in direct proportion to component wear.S p e e dThe running speed of the pump is a direct indicator of the extent of wear.This enables long term planning of maintenance intervals and targeting ofspecific servicing tasks.We manufacture extremely compact Triplex and Quintuplex pump units for injection of Methanol, LDHI,Glycol and a range of inhibitors.Hammelmann high pressure pump units in the pressure range up to 15,000 psi (1035 bar) havedeveloped into the standard choice for offshore methanol injection applications with a reputation for extreme reliability and minimal maintenance requirements.Compact constructionExtensiveperformancerangeWith both Triplex andQuintuplex pumpsavailable we cansupply a veryextensive range offlow rates andoperating pressures.Power ratingsup to 1000 HPup to 750 kWFlow ratesup to 530 gpmup to 2000 l/minOperating pressuresup to 55,000 psiup to 3800 barHammelmann pumps producemaximum performance from aminimal footprint which is the resultof combining a compact integralspeed reduction gear end with theconcept of a vertical configuration.The vertical configuration channelsoscillating forces directlydownwards into the base structure.Unwanted lateral oscillations asproduced by horizontal pumps donot occur.The integral speed reducer with twinhelical gears arranged in a herringbone configuration ensures smoothrunning and even powertransmission without axially loadingthe bearings.A selection of gear ratios isavailable to allow the optimal choiceof driver.

Methods A total of 74 patients with suspected diabetes admitted to Siyang Kangda Hospital from January 2022 to January 2023 were selected as the research objects. The levels of glycosylated hemoglo‐bin (HbA1c) and serum C-peptide were detected. Oral glucose tolerance test (OGTT) was used as the gold standard. The sensitivity, specificity and diagnostic coincidence rate of serum C-peptide combined with glycosylated hemoglo‐bin detection and single item detection were statistically analyzed. Results According to the results of glucose toler‐ance test, 67 patients were diagnosed in 74 patients with suspected diabetes, and the diagnosis rate was 90.54% (67/ 74). Compared with the single detection of serum C-peptide and HbA1c, the sensitivity of combined detection of se‐rum C peptide and HbA1c was higher, and the difference was statistically significant (P<0.05). The specificity of com‐bined detection of serum C-peptide and HbA1c was slightly higher than that of single detection of serum C-peptide and HbA1c, but the difference was no statistically significant (P>0.05). The diagnostic coincidence rate of combined detection was significantly higher than that of single detection of serum C-peptide and HbA1c, and the difference was statistically significant (P<0.05). Conclusion Serum C-peptide and glycosylated hemoglobin are important reference indexes for clinical diagnosis of diabetes mellitus, and changes in the expression levels of the two can help to detect the insulin secretion function of patients and assess the severity of the disease.

Expression, Purification and Crystallization of

Expression, Purification and Crystallization of the Mycobacterium Tuberculosis HSP16.3 Molecular Chaperone Background of Mycobacterium Tuberculosis HSP16.3HSP16.3, a 16.3 kDa protein from Mycobacterium Tuberculosis, was originally identified as a prominent antigen (Kingston et al., 1987). During the stationary phase, HSP16.3 is maximally expressed and becomes a main protein of the latent phase (Yuan et al., 1996). Previous studies showed that HSP16.3 can make the cell structure stable and prevent stationary Mycobacterium Tuberculosis from autolysing (Cunningham et al., 1998). In previous studies, HSP16.3 was found as one of theα-crystallin-related small heat shock proteins (sHSP) with molecular chaperone activity. Experiments in vitro revealed that HSP16.3 can suppress the thermal aggregation of citrate synthase at 39.5˚C, without consumption of A TP (Chang et al., 1996).Now the Mycobacterium Tuberculosis HSP16.3 gene was cloned to the plasmid pSTE-HSP16.3, and transformed to E.Coli.

Betamethasone sodium phosphate (BSP) injection is a phosphate preparation of betamethasone, which is widely used as a antenatal corticostemids (ACS) drug in clinical practice. There is sufficient evidence for the treatment of premature birth with BSP, and BSP has been included in national guidelines. However, the evidence related to its treatment of premature birth is mainly in high-income countries, and there is less evidence in low to middle-income countries. There is insufficient clinical research on the efficacy and safety of BSP in obstetric applications in China. There are few clinical studies on the direct comparison of efficacy and safety between betamethasone and dexamethasone, and the follow-up study of BSP in treating premature in childhood and adulthood is still insufficient. Further research is needed to provide a decision-making basis for the scientific and rational use of medication in preterm birth.[Key words] Betamethasone sodium phosphate injection; Premature birth; Respiratory distress syndrome; Septicemia; Intraventricular hemorrhage倍他米松磷酸钠(betamethasone sodium phosphate,BSP)是倍他米松的水溶性衍生物,也是地塞米松磷酸钠的16位差向异构体[1]。

Methods A total of 82 patients with refractory type 2 diabe⁃tes mellitus treated in Ganyu District People's Hospital from June 2022 to June 2023 selected as the study objects and divided into two groups by random number table method. The control group (n=40) was treated with metformin hydro⁃chloride tablets + insulin glargine, and the observation group (n=42) was treated with metformin hydrochloride tablets+ Degu asparton double insulin. The differences and complications of blood glucose level, blood glucose fluctuation and other related indicators before and after treatment were compared between the two groups. Results Before treatment, there were no statistically significant differences in blood glucose levels between the two groups of patients (P>0.05). After treatment, blood glucose decreased in both groups, and the degree of blood glucose decrease in the observation group was significantly lower than that in the control group, the differences were statistically significant (P<0.05). Be⁃fore treatment, there were no statistically statistical significance differences in the indexes related to blood glucose fluctuation between the two groups, including mean blood glucose, standard deviation of blood glucose level, largest amplitude of glycemic excursion, and postprandial blood glucose fluctuation (P>0.05). After treatment, the relevant in⁃dexes of blood glucose fluctuation were improved in both groups, and the improvement degree of the observation group was significantly better than that of the control group, the differences were statistically significant (P<0.05). The com⁃plication rate of the observation group was lower than that of the control group, the difference was statistically signifi⁃cant (P<0.05).

甘菊CMO同源基因的分离与表达分析

甘菊CMO同源基因的分离与表达分析

甘菊CMO同源基因的分离与表达分析牛雅静;王淑慧;黄河;戴思兰【摘要】利用半嵌套巢式PCR结合RACE技术从菊科植物甘菊[Chrysanthemum lavandulifolium(Fisch.ex Trautv.)Makino]中分离得到了一个长度为1 450 bp的片段.序列分析结果表明,其开放阅读框全长1 140bp,编码379个氨基酸残基;在GenBank 比对并进行系统进化分析可知,该片段为CMO同源基因,命名为ClCMO.利用不同胁迫处理进行分析发现,在非胁迫条件下ClCMO基因在甘萄茎、叶、花叶中均有表达信号,在根中没有表达;其可以响应干旱、高盐胁迫和脱落酸(ABA)的诱导,不响应冷热胁迫,并且其表达在水杨酸(SA)诱导下受抑制.这些结果表明,ClCMO基因是提高植物耐干旱、高盐能力的有效基因资源.【期刊名称】《生物技术通报》【年(卷),期】2012(000)004【总页数】5页(P58-62)【关键词】胆碱单加氧酶(CMO);甘氨酸甜菜碱(GB);非生物胁迫;表达;甘菊【作者】牛雅静;王淑慧;黄河;戴思兰【作者单位】北京林业大学园林学院,北京100083;北京林业大学园林学院,北京100083;北京林业大学园林学院,北京100083;北京林业大学园林学院,北京100083【正文语种】中文渗透胁迫(osmotic stress)是植物生长发育过程中所面临的最主要胁迫之一,脯氨酸、山梨醇、海藻糖和甜菜碱等渗透调节物质在植物抵御渗透胁迫中起到了重要的作用。

甘氨酸甜菜碱(glycine betaine,GB)是甜菜碱的一种,是植物中广泛存在的一类渗透调节物质,它主要通过两步酶促反应合成:首先是由胆碱(choline)在胆碱单加氧酶(choline monooxygenase,CMO)的催化下生成甜菜碱醛(betaine aldehyde)[1],随后甜菜碱醛在甜菜碱醛脱氢酶(betaine aldehyde dehydragensase,BADH)的催化下合成甘氨酸甜菜碱[2]。
