ABSTRACT

OBJECTIVE To correctly identify and deal with the adverse drug reaction as pancytopenia caused by isavuconazonium and to provide reference for the safe use of isavuconazonium. METHODS Clinical pharmacists analyzed a case of severe infection and renal insufficiency who experienced pancytopenia after using isavuconazonium. Clinical pharmacists screened the drugs used during hospitalization and evaluated the relationship between this adverse drug reaction and isavuconazonium, as well as the possible mechanisms, based on the half-life of the drugs and relevant literature. RESULTS & CONCLUSIONS The relationship between pancytopenia and isavuconazonium was assessed as “possibly related”. When using isavuconazonium, attention should be paid to avoiding the combination of drugs with the same mechanism or potential interaction. For patients who have a course of treatment for more than 2 weeks, have hematological abnormalities or complicated with liver and renal insufficiency, or should use it combined with other drug with same mechanism, it may be considered to increase the frequency of blood routine monitoring.

ABSTRACT

Aim To investigate whether the Enphorbia lunulata Bge extract regulates the proliferation, migration and invasion of colorectal cancer cells induced by interleukin-1β(IL-1β)through miR-30a-5p/nuclear factor κB(NF-κB). Methods HT29 cells were divided into NC group, IL-1β group, low-dose(2.5 mg·L-1)+IL-1β group, middle-dose(5 mg·L-1)+IL-1β group, high-dose(10 mg·L-1)+IL-1β group, miR-NC+IL-1β group, miR-30a-5p+IL-1β group, anti-miR-NC+high-dose+IL-1β group, anti-miR-30a-5p+high-dose+IL-1β group. Cell counting kit-8 method was used to detect cell proliferation activity in each group, clone formation experiment was applied to assess cell clones, Transwell method was employed to monitor cell migration and invasion, Western blot was performed to determine the protein expression level, and qRT-PCR was employed to detect the expression level of miR-30a-5p. Results Compared with the NC group, the proliferation activity, cell clone number, migration and invasion number of colorectal cancer cell HT29 in IL-1β group increased, and the expression level of miR-30a-5p decreased(all P<0.01). Compared with the IL-1β group, the proliferation activity, the number of cell clones, the number of migration and invasion of colorectal cancer cell HT29 decreased, and the expression level of miR-30a-5p increased(all P<0.01); The expression level of p-p65 in the high-dose+IL-1β group was lower than that in the IL-1β group(P<0.01). The proliferation activity, cell clone number, migration and invasion number of colorectal cancer cell HT29 in the miR-30a-5p+IL-1β group were lower than those in the miR-NC+IL-1β group(all P<0.01). The proliferation activity, cell clone number, migration and invasion number of colorectal cancer cell HT29 in the anti-miR-30a-5p+high-dose+IL-1β group were higher than those of anti-miR-NC+high-dose+IL-1β group(all P<0.01). Conclusions Enphorbia lunulata Bge extract can inhibit the proliferation, migration and invasion of colorectal cancer cells induced by IL-1β by up-regulating miR-30a-5p and down-regulating the activity of NF-κB signaling pathway.

ABSTRACT

To investigate the cellular target selectivity of small molecules targeting thioredoxin reductase 1, we reported the construction and functional research of a stable TrxR1 gene (encode thioredoxin reductase 1) knockout HCT-116 cell line. We designed and selected TrxR1 knockout sites according to the TrxR1 gene sequence and CRISPR/Cas9 target designing principles. SgRNA oligos based on the selected TrxR1 knockout sites were obtained. Next, we constructed knockout plasmid by cloning the sgRNA into the pCasCMV-Puro-U6 vector. After transfection of the plasmid into HCT-116 cells, TrxR1 knockout HCT-116 cells were selected using puromycin resistance. The TrxR1 knockout efficiency was identified and verified by DNA sequencing, immunoblotting, TRFS-green fluorescent probe, and cellular TrxR1 enzyme activity detection. Finally, the correlation between TrxR1 expression and cellular effects of drugs specifically targeting TrxR1 was investigated by CCK-8 assay. The results demonstrated that the knockout plasmid expressing the sgRNA effectively knocked-out TrxR1 gene within HCT-116 cells, and no expression of TrxR1 protein could be observed in stable TrxR1 knockout HCT-116 (HCT116-TrxR1-KO) cells. The TrxR1-targeting inhibitor auranofin did not show any inhibitory activity against either cellular TrxR1 enzyme activity or cell proliferation. Based on these results, we conclude that a stable TrxR1 gene knockout HCT-116 cell line was obtained through CRISPR/Cas9 techniques, which may facilitate investigating the role of TrxR1 in various diseases.

ABSTRACT

Objective:To summarize the surgical experience of carotid body tumor (CBT)and analyze the risk factors.Methods:The clinical and follow-up data of 133 patients with carotid body tumor undergoing surgery at the First Medical Center of PLA General Hospital from Nov 2005 to Apr 2019 were retrospectively analyzed.Results:All of 142 tumors were successfully resected. No patients died perioperatively. Thirty-three (23.2%) cases underwent simple tumor resection, 82 (57.8%) cases underuent tumor resection combined with external carotid artery ligation, 13 (9.2%) cases did internal carotid artery reconstruction, 10 (7.0%) cases had total or external carotid artery repairment, and 4 (2.8%) cases underwent total or internal carotid artery ligation. There were 53 complications, including 43 cases of cranial nerve injury, with an average operating time of 161min (60-500 min), an average blood loss of 308 ml (20-3 000 ml). The follow-up time ranged from 1 to 162 months. No death occurred during the follow-up period.Conclusions:Tumor size and Shamblin typing are surgical risk factors. Most of ShamblinⅠtype tumor can do simple resection, but type Ⅱ and Ⅲ often need to ligate the external carotid artery. Use of great saphenous vein has a favorable long-term patency rate.

ABSTRACT

AIM: To investigate the effect of nobiletin (Nob) on cardiomyocyte hypertrophy induced by high glucose and its mechanism. METHODS: Neonatal rat cardiomyocytes (NRCMS) were stimulated with high glucose (HG) to establish cardiomyocyte hypertrophy and nobiletin was given. Cell viability was measured by MTT assay. C-myc and Nppa mRNA levels were detected by qRT-PCR. Cellular surface area was detected by immunofluorescence, and Nrf2 and HO-1 protein expressions were detected by Western blot. RESULTS: After stimulation with 33.3 mmol/L HG for 48 h, the survival rate of NRCMS was significantly decreased, C-myc, Nppa mRNA levels and cellular surface area were significantly increased, Nrf2 and HO-1 protein expression were significantly decreased (P<0.05). After Nob treatment, compared with HG group, cellular surface area, Nrf2 and HO-1 protein expression were significantly increased, C-myc and Nppa mRNA levels were significantly decreased. The above indexes were reversed by using Nrf2 inhibitor. CONCLUSION: Nob inhibits cardiomyocyte hypertrophy induced by high glucose, and its mechanism may be related to the activation of Nrf2/HO-1 signaling pathway.

ABSTRACT

Objective:To investigate the effect of miR-106a on osteoarthritis.Methods:Twenty-four S-D female rats were randomly divided into three groupsaccording to the random number table: the sham operation group, the osteoarthritis (OA) group and the miR-106a mimic group. Eightweeks after operation, all rats were killed and articular cartilage was separated from the medial tibial plateau of each rat. Histopathology was used to observe the morphological changes and denatured quantity of chondrocytes, the level of inflamm-atory cytokines [interleukin (IL)-1, IL-6, tumor necrosis factor (TNF)-β 1], the expression of apoptosis receptor p65, DR6 protein and the expression of mir-106a RNA. The mean between groups was compared by one-way analysis of variance (ANOVA), and the least significant difference (LSD)- t test was used for the comparison between the two groups. Results:Histopathological staining results showed that the articular surface and synovium of rats in the sham operation group were intact, the chondrocytes were arranged horizontally, and the articular cartilage edge was smooth.In the OA group, the articular cartilage edge was seriously damaged and the arrangement of chondrocytes was disordered.In the miR-106a simulation group, the cartilage structure tended to be normal, occasionally uneven, and the articular cartilage surface was not smooth. Compared with sham operation group, the expression of miR-106a in OA group was significantly decreased ( F=918.02, P<0.01); the expression of inflammatory mediators (IL-1, IL-6, TNF-β) in OA group was also signifi-cantly increased ( F=41 914.86, P<0.01; F=64 85.16, P<0.01; F=8 873.31, P<0.01). The expression levels of DR6 and p65 in OA group were higher ( F=2 319.338, P<0.01; F=1 253.882, P<0.01). Compared with OA group, the levels of inflammatory mediators (IL-1, IL-6, TNF-β) in miR-106a mimetic group were significantly decreased (1.270±0.020, 6.040±0.170, 5.690±0.080), and the expressions of DR6 and p65 were decreased (1.53±0.09, 0.41±0.04). Conclusion:miR-106a can reduce the inflammatory changes and the degeneration of chondrocytes in osteoarthritis rats.

ABSTRACT

In canonical Wnt/β-catenin signaling pathway, β-catenin/TCF4 (T-cell factor 4) interaction plays an important role in the pathogenesis and development of non-small cell lung cancer (NSCLC), and it is tightly associated with the proliferation, chemoresistance, recurrence and metastasis of NSCLC. Therefore, suppressing β-catenin/TCF4 interaction in Wnt/β-catenin signaling pathway would be a new therapeutic avenue against NSCLC metastasis. In this study, considering the principle of enzyme-linked immunosorbent assay (ELISA), an optimized high-throughput screening (HTS) assay was developed for the discovery of β-catenin/TCF4 interaction antagonists. Subsequently, this ELISA-like screening assay was performed using 2 μg/mL GST-TCF4 βBD and 0.5 μg/mL β-catenin, then a high Z' factor of 0.83 was achieved. A pilot screening of a natural product library using this ELISA-like screening assay identified plumbagin as a potential β-catenin/TCF4 interaction antagonist. Plumbagin remarkably inhibited the proliferation of A549, H1299, MCF7 and SW480 cell lines. More importantly, plumbagin significantly suppressed the β-catenin-responsive transcription in TOPFlash assay. In short, this newly developed ELISA-like screening assay will be vital for the rapid screening of novel Wnt inhibitors targeting β-catenin/TCF4 interaction, and this interaction is a potential anticancer target of plumbagin in vitro.

ABSTRACT

Objective:To summarize the midterm to long-term outcomes and experiences of endovascular treatment (ET) of spontaneous isolated superior mesenteric artery dissection (SISMAD).Methods:The clinical data of 31 SISMAD patients from Jan 2011 to Dec 2019 treated with ET was retrospectively analyzed.Results:Successful ET was achieved in 29 patients with a technical success rate of 93.5%. A total of 36 self-expandable bare stents were planted in 28 patients and plain old balloon angioplastry (POBA) was performed in 1 patient. Abdominal pain disappeared within 24 hours in 89.3% of the patients after stenting. The rate of perioperative complication was 3.2%. There was no SMA dissection rupture bleeding, nor perioperative death occurred. The mean follow-up time was 53.5 (range, 6 to 110) months. There was no dissecting aneurysm formation, no SMA rupture and bleeding, and no stent rupture during the follow-up. The post ET 1-year, 3-year, and 5-year free from reintervention rate were 100%, 100%, and 91.7%, respectively.Conclusions:ET for SISMAD is safe and effective with satisfactory perioperative and midterm to long-term outcomes.

ABSTRACT

The main protease (Mpro) of SARS-CoV-2 is a highly conserved and mutation-resistant coronaviral enzyme, which plays a pivotal role in viral replication, making it an ideal target for the development of novel broad-spectrum anti-coronaviral drugs. In this study, a codon-optimized Mpro gene was cloned into pET-21a and pET-28a expression vectors. The recombinant plasmids were transformed into E. coli Rosetta(DE3) competent cells and the expression conditions were optimized. The highly expressed recombinant proteins, Mpro and Mpro-28, were purified by HisTrapTM chelating column and its proteolytic activity was determined by a fluorescence resonance energy transfer (FRET) assay. The FRET assay showed that Mpro exhibits a desirable proteolytic activity (25 000 U/mg), with Km and kcat values of 11.68 μmol/L and 0.037/s, respectively. The specific activity of Mpro is 25 times that of Mpro-28, a fusion protein carrying a polyhistidine tag at the N and C termini, indicating additional residues at the N terminus of Mpro, but not at the C terminus, are detrimental to its proteolytic activity. The preparation of active SARS-CoV-2 Mpro through codon-optimization strategy might facilitate the development of the rapid screening assays for the discovery of broad-spectrum anti-coronaviral drugs targeting Mpro.

ABSTRACT

Polo-like kinase 1 (Plk1) is widely regarded as one of the most promising targets for cancer therapy due to its essential role in cell division and tumor cell survival. At present, most Plk1 inhibitors have been developed based on kinase domain, some of which are in clinical trial. However, inhibitors targeting kinase domain face off-target effect and drug resistance owing to the conserved nature and the frequent mutations in the ATP-binding pocket. In addition to a highly conserved kinase domain, Plk1 also contains a unique Polo-Box domain (PBD), which is essential for Plk1's subcellular localization and mitotic functions. Inhibitors targeting Plk1 PBD show stronger selectivity and less drug resistance for cancer therapy. Therefore, Plk1 PBD is an attractive target for the development of anti-cancer agents. In this review, we will summarize the up-to date drug discovery for targeting Plk1 PBD, including the molecular structure and cellular functions of Plk1 PBD. Small-molecule inhibitors targeting Plk1 PBD not only provide an opportunity to specifically inhibit Plk1 activity for cancer treatment, but also unveil novel biological basis regarding the molecular recognition of Plk1 and its substrates.

ABSTRACT

Objective@#To evaluate the safety and efficacy of the drug coated balloon(DCB) for complex TASC C/D superficial femora-popliteal artery diseases.@*Methods@#Patency, target lesion revascularization (TLR) rate, clinical improvement and safety endpoints of femora-popliteal lesions in 68 patients from PLA General Hospital treated with DCB were retrospectively analyzed from June 2016 to June 2018. The mean age of the patients were (72.7±13.2) years old. Rutherford categories were from 2 to 5, and ABI baseline were 0.56±0.22.@*Results@#There were 76 limbs treated by DCB in total in this study. Mean lesion length was (26.7±15.3) cm. 73.6% of lesions were totally occluded, 26.4% were of stenosis and 61.8% were highly calcified. Stent implantation was performed in 36.8% cases. Kaplan Meier estimates of primary patency were 74.2%±7.6% and 67.7%±6.4% at 1 and 2 years, respectively, whereas freedom from TLR was 81.4%±5.1% and 73.6%±5.4%. ABI were 0.83±0.16 at 1 year, and 0.79±0.24 at 2 years. Major amputation rate was 2.9% and mortality rate was 2.9% and 4.4% at 1 year and 2 years respectively. Diabetes, highly calcification, renal insufficiency and re-stenotic lesions were identified as predictors of restenosis.@*Conclusions@#DCB are safe and effective in delaying restenosis in complex TASC C/D superficial femora-popliteal artery disease as found by midterm follow-up.

ABSTRACT

Objective@#To compare the clinical features, ultrasonic imaging manifestations and therapeutic evaluations between elderly onset rheumatoid arthritis (EORA) and EORA with osteoarthritis (OA).@*Methods@#Eighty-eight patients with rheumatoid arthritis were divided into two groups: group EORA (n=36) and group EORA+OA (n=52). The onset age of all patients was 60 years or older. General conditions, joint involvement distribution, ultrasonic manifestations and disease activity scores (DAS28-3) of patients in the two groups were analyzed. The χ2 test/Fisher's exact probability test and the Student's t test/Mann-Whitney U test were used to analyze data.@*Results@#There was no significant difference in the proportion of male and female patients and erythrocyte sedimentation rate (ESR) between the two groups (P>0.05). The onset age of patients in group EORA+OA [(68±4) years old] was higher than that in group EORA [(65±4) years old], and the difference was statistically significant (t=-3.465, P=0.001). Duration of the disease and body mass index in group EORA+OA were significantly higher respectively than those in group EORA. Joint involvement in the two groups was mainly found in shoulder, wrist, Metacarpophalangeal joint (MCP)2, MCP3, proximal inter-phalangeal joint (PIP)2, PIP3, PIP4, and knee joint (34.7%-86.5%). The percentage of MCP2[36.5%(38/104), 70.8%(51/72); χ2=20.02, P<0.01], MCP3[33.7%(35/104), 59.7%(43/72); χ2=11.72, P=0.001], MCP4[4.8%(5/104), 22.2%(16/72); χ2=12.28, P<0.01], PIP2[69.2%(72/104), 83.3%(60/72); χ2=4.51, P=0.034] and PIP3[53.8%(56/104), 70.8%(51/72); χ2=5.15, P=0.023] in the EORA+OA group was lower while the percentage of MCP1, DIP 2, DIP3, DIP4 and knee joints were higher than that in the EORA group (P<0.05). In group EORA+OA, the synovial thickness of the wrist joints [(4.2±0.5) mm] and knee joints [(7.7±0.8) mm] were significantly thicker than those in group EORA [(3.2±0.9) mm; (6.3±0.8) mm, t=-5.82, P<0.01; t=-7.22, P<0.01]; The proportion (70.0%) of level 2 and 3 of patients' wrist joint synovium pannus blood flow and knee joint synovium pannus in group EORA+OA were increased than group EORA (51.9%; 52.3%), the difference between the two groups was statistically significant (χ2=4.64, P=0.031; χ2=4.43, P=0.035). There was no significant difference in DAS28-3 scores between the two groups before patients received treatment. After 2 weeks and 12 weeks of glucocorticoid treatment, DAS28-3 scores in group EORA [3.62(2.88, 4.03); 2.35(2.26, 2.62) points] were significantly lower than group EORA+OA [5.01(4.68, 5.26); 3.38(2.28, 3.83) points] (Z=-7.766, P<0.01; Z=-3.461, P<0.01).@*Conclusion@#Compared with patients of EORA alone, patients of EORA with OA have more obvious joint symptoms, MCP1, DIP and knee joint are susceptible to the co-involvement among them, longer duration of disease, and were prone to synovial hyperplasia and pannus flow formation. The therapeutic effects of glucocorticoid on joint inflammation in patients of EORA alone are superior to those patients of EORA with OA.

ABSTRACT

One hundred and ten patients with obstinate facial palsy were randomly divided into study group and control group with 55 cases in each group. Both groups received electropuncture on face acupoints five times a week, the study group received additional acupuncture on Zhongzhen six acupoints, subsequently fire needles were used for Yangbai (GB 14), Quanliao (SI 18), Dicang (ST 4) and Jiachengjiang (Extra) acupoints twice a week. And the treatment courses lasted for four weeks. The House-Brackmann (HB) scale and Self-Rating Anxiety Scale (SAS) were used for evaluation of facial nerve function and anxiety status before and after treatment, respectively. One hundred and four cases completed the treatment in the two groups. Before treatment there were no significant differences in HB and SAS scores between study and control groups (Z=-0.271, P=0.79; Z=-1.689, P=0.09). After 4 weeks of treatment the HB and SAS scores in both group were significantly improved (Z=-5.652, Z=-5.038, all P<0.01; Z=-6.050, Z=-5.332, all P<0.01); however, there were significant differences in HB scale and SAS scores after treatment between two groups (Z=-2.066, Z=-2.884, all P<0.05). The electric acupuncture on face acupoints plus Zhongzhen six acupoints combined with fire acupuncture can effectively improve facial nerve function and anxiety state in patients with obstinate facial palsy.

Objective To compare the clinical features,ultrasonic imaging manifestations and therapeutic evaluations between elderly onset rheumatoid arthritis (EORA) and EORA with osteoarthritis (OA).Methods Eighty-eight patients with rheumatoid arthritis were divided into two groups:group EORA (n=36)and group EORA+OA (n=52).The onset age of all patients was 60 years or older.General conditions,joint involvement distribution,ultrasonic manifestations and disease activity scores (DAS28-3) of patients in the two groups were analyzed.The x2 test/Fisher's exact probability test and the Student's t test/Mann-Whitney U test were used to analyze data.Results There was no significant difference in the proportion of male and female patients and erythrocyte sedimentation rate (ESR) between the two groups (P>0.05).The onset age of patients in group EORA+OA [(68±4) years old] was higher than that in group EORA [(65±4) years old],and the difference was statistically significant (t=-3.465,P=0.001).Duration of the disease and body mass index in group EORA+OA were significantly higher respectively than those in group EORA.Joint involvement in the two groups was mainly found in shoulder,wrist,Metacarpophalangeal joint (MCP)2,MCP3,proximal interphalangeal joint (PIP)2,PIP3,PIP4,and knee joint (34.7%-86.5%).The percentage of MCP2 [36.5%(38/104),70.8% (51/72);x2 =20.02,P <0.01],MCP3 [33.7% (35/100),59.7% (43/72);x2 =11.72,P =0.001],MCP4 [4.8% (5/100),22.2% (16/72);x2 =12.28,P<0.01],PIP2 [69.2% (72/104),83.3% (60/72);x2 =4.51,P=0.034]and PIP3 [53.8%(56/100),70.8%(51/72);x2=5.15,P=0.023] in the EORA+OA group was lower while the percentage of MCP1,DIP 2,DIP3,DIP4 and knee joints were higher than that in the EORA group (P<0.05).In group EORA+OA,the synovial thickness of the wrist joints [(4.2±0.5) mm] and knee joints [(7.7±0.8) mm]were significantly thicker than those in group EORA [(3.2±0.9) mm;(6.3±0.8) mm,t=-5.82,P<0.01;t=-7.22,P<0.01];The proportion (70.0%) of level 2 and 3 of patients' wrist joint synovium pannus blood flow and knee joint synovium pannus in group EORA+OA were increased than group EORA (51.9%;52.3%),the difference between the two groups was statistically significant (x2=4.64,P=0.031;x2=4.43,P=0.035).There was no significant difference in DAS28-3 scores between the two groups before patients received treatment.After 2 weeks and 12 weeks of glucocorticoid treatment,DAS28-3 scores in group EORA [3.62 (2.88,4.03);2.35 (2.26,2.62) points] were significantly lower than group EORA+OA [5.01(4.68,5.26);3.38(2.28,3.83) points](Z=-7.766,P<0.01;Z=-3.461,P<0.01).Conclusion Compared with patients of EORA alone,patients of EORA with OA have more obvious joint symptoms,MCP1,DIP and knee joint are susceptible to the coinvolvement among them,longer duration of disease,and were prone to synovial hyperplasia and pannus flow formation.The therapeutic effects of glucocorticoid on joint inflammation in patients of EORA alone are superior to those patients of EORA with OA.

ABSTRACT

Objective@#Screen the pathogenic genes of a pedigree with clinical manifestation of familial dilated cardiomyopathy in Inner Mongolia.@*Methods@#A total of 3 patients with dilated cardiomyopathy and 20 family members from the same family were examined in Ordos Central Hospital in Inner Mongolia from October, 2003 to August, 2017. Data on medical history, physical examinations, electrocardiograms, and echocardiography were obtained. 5 ml peripheral blood was sampled for per person. Chip Capture Sequencing technology was used to capture all the exons and splice sites of the genes that associated with hereditary cardiomyopathy and hereditary arrhythmia. The mutations in these genes were detected by high-throughput sequencing. All suspected pathogenic loci identified by high-throughput sequencing were verified by Sanger sequencing used for mutation detection. One hundred and fifty gender, age and race matched healthy people were included as the control group.@*Results@#Pathogenic gene variations were detected in 3 symptomatic family members and 1 carrier from the pedigree. Five pathogenic gene variations were identified in the proband (Ⅱ1), a pSer236Gly and a pArg215Cys variation in the MYBPC3 gene, a pGln90Arg variation in the DSP gene, and pAsn2912Asp and pGlu2910Val variation in the DMD gene. One pathogenic variation was detected in Ⅲ3, which was a pArg215Cys variation in the MYBPC3 gene. Two pathogenic variations were detected in Ⅲ7, a pSer236Gly variation in the MYBPC3 gene and a pGln90Arg variation in the DSP gene. Two pathogenic variations were detected in the Ⅳ7, a pSer236Gly variation in the MYBPC3 gene and a pGln90Arg variation in the DSP gene. No gene variation loci were detected in the other family members and the control group.@*Conclusion@#MYBPC3 gene, DSP gene and DMD gene variations are present in the familial dilated cardiomyopathy pedigree from Inner Mongolia, and these variations may be related with familial dilated cardiomyopathy.

ABSTRACT

To prepare polyclonal antibody (PcAb) against Escherichia coli filamentous thermosensitive protein Z (Ec-FtsZ), the artificially synthesized gene fragment coding Ec-FtsZ was subcloned into pET-22b(+) plasmid, and Ec-FtsZ protein was expressed in E. coli BL21(DE3) cell under an optimal bacterial expression condition. Then Ec-FtsZ protein was purified by HisTrap affinity chromatography, and the GTPase (Guanosine triphosphatase) activity of purified Ec-FtsZ protein was further analyzed by malachite green assay. Subsequently, the purified Ec-FtsZ protein was used to immunize rat subcutaneously for preparation of anti-Ec-FtsZ PcAb. The results of enzyme-linked immunosorbent assay (ELISA), Western blotting analysis and immunofluorescence assay showed that the titer of PcAb was 1:256 000, and PcAb exhibited a perfect antigenic specificity against purified and endogenous Ec-FtsZ protein. All these data indicated that the anti-Ec-FtsZ PcAb is successfully prepared, which can be used for further cellular function study and biochemical analysis of Ec-FtsZ protein in vivo.
