Abstract
Background Compound Taxus capsule, as an antineoplastic Chinese patent drug, has been increasingly applied as an adjunctive treatment for the management of non-small-cell lung cancer (NSCLC) and some other malignancies, but research about its antitumor activity and radiosensitization effect on hepatocellular carcinoma (HCC) cells is very rare. Purpose To investigate the antitumor activity and radiosensitization effect of Compound Taxus on HCC cells and to preliminarily explore the possible molecule mechanisms involved. Methods Cell viability, cell cycle distribution, apoptosis, DNA damage repair and protein expression levels were detected by CCK-8 assay, flow cytometry, immunofluorescence staining, western blotting analysis and immunohistochemical staining, respectively. The migration and invasion activities and vasculogenic mimicry (VM) formation and angiogenesis were evaluated by tube formation and VM formation assay. Radiation survival curves were obtained from the colony formation assay in human HCC cell lines, Smmc7721 and Bel7402 cells, pretreated with or without Compound Taxus before receiving X-ray irradiation. A Bel7402 tumor-bearing mouse model was established and the radiosensitization effect of Compound Taxus in vivo was evaluated by analyzing tumor volume and tumor weight in different groups receiving different treatments. Results Compound Taxus decreased viability, induced G2/M arrest, promoted apoptosis, suppressed migration and invasion, and inhibited VM formation and angiogenesis in Smmc7721 and Bel7402 cells. Furthermore, Compound Taxus inhibited irradiation-induced DNA damage repair, enhanced the radiosensitivity of Smmc7721 and Bel7402 cells and improved the anti-tumor therapeutic efficacy of irradiation in Bel7402 tumor-bearing mice. Radiotherapy in combination with Compound Taxus showed the best tumor inhibition compared to that of Compound Taxus alone or irradiation alone. In addition, Compound Taxus significantly down-regulated NF-κB p65, p-NF-κB p65 and Bcl-2, and up-regulated Bax in vitro and in vivo, yet NF-κB p65 overexpression reversed the proapoptotic effect of Taxus on HCC cells, indicating that the NF-κB signaling pathway might be an important signal mediator in the Compound-Taxus-modulated biological responses. Conclusion Our findings suggest that Compound Taxus shows marked antitumor activity and significant radiosensitization effect on HCC cells, making it possible for Compound Taxus to become a promising auxiliary modality for HCC management and a potential radiosensitizer of HCC in the future.

Abstract
In recent years, great progress has been made in the treatment of Stanford type B aortic dissection, especially endovascular repair technology has become the main treatment. However, it is only used to repair the primary tear, the residual tears and false lumen are often left at the distal end, which causes adverse events such as distal aortic dilatation or even rupture. At present, there are many studies on the influencing factors of aortic remodeling, which provide some references for the prognosis of patients.The aorta carries the transportation of blood flow, and various factors affecting hemodynamics also affect the remodeling of aorta. Some researchers reported several factors related to negative remodeling and added auxiliary techniques, and achieved gratifying results. However, because of the different conditions of each patient, the specific treatment method is still unclear, the factors affecting the aortic remodeling effect also have not been thoroughly studied. Clarifying the influencing factors of negative remodeling is helpful to screen high-risk patients, optimize the treatment plan and improve the prognosis.

Abstract
BACKGROUND Gastric cancer is the fifth most common malignancy worldwide. In early stages, no obvious symptoms are usually observed in gastric cancer patients, and it is especially hard to distinguish gastric cancer from benign gastric diseases, resulting in delayed diagnosis and poor prognosis. Common biomarkers of gastric cancer, such as CEA and CA19-9, are also elevated in benign diseases. There is an urgent need to develop a convenient and reliable biomarker for differentiating between gastric cancer and benign gastric diseases. METHODS This study retrospectively analyzed the data of 126 patients, including 73 gastric cancer patients and 53 benign gastric disease patients. Patient characteristics collected for analysis included age, gender, laboratory data, and clinical staging. Unpaired t-test was used to check the difference of cholinesterase level between the gastric cancer group and the benign gastric disease group. Kruskal Wallis H test and Mann-Whitney U test were used to check the difference of cholinesterase level among different stage groups. Receiver operating characteristic (ROC) curve was used to assess whether cholinesterase level can be used as a biomarker for differentiating between gastric cancer and benign gastric diseases. RESULTS Serum cholinesterase level was decreased significantly in the gastric cancer group in comparison to that of the benign gastric disease group (p < 0.001). In addition, cholinesterase level of stage IV patients was significantly lower than stage I patients. ROC curve analysis revealed that with a cutoff of 5,969.00 U/L, cholinesterase level showed an area under the curve of 0.819 (95% CI 0.732 - 0.905, p < 0.001) in differentiating between gastric cancer and benign gastric diseases. No significant difference in the levels of CEA and CA19-9 was observed between gastric cancer patients and benign gastric disease patients. CONCLUSIONS This study indicated that serum cholinesterase level could be considered as a potential biomarker for differentiating between gastric cancer and benign gastric diseases.

Abstract
Neuroendocrine tumors (NETs) generally arise from endocrine cells of gut and bronchi. Primary NETs of spine are extremely rare and have been described in cervical spine, lumbar spine, sacrum, and coccyx. So far, primary NETs in thoracic spine have not been reported yet. Here we described a 46-year-old Chinese woman with NET in thoracic spine. Neuroimaging revealed a mass behind the vertebral body of T11, abnormal changes in the adnexa and surrounding soft tissue and compression of the spinal cord. She received a total resection of the tumor and T11 corpectomy. Histopathological examination and immunohistochemical staining proved the tumor to be a rare spinal NET. PET-CT and other examinations ruled out the existence of tumors in any other site. So, she was diagnosed with NET of thoracic spine. The patient received postoperative etoposide and nedaplatin chemotherapy for four cycles, and she recovered well with no evidence of tumor recurrence or metastasis during six-month medical follow-up. Spine location of NETs should be first considered as a metastatic disease unless there is proof ruling out the possibility. Complete tumor resection is the most effective therapy in NETs of spine and should be considered in priority, and chemotherapy and radiotherapy should be considered on an individual basis.

Abstract
Objective: To investigate the clinicopathological features of gangliocytic paraganglioma(GP). Methods: Clinical data and pathological diagnosis of the 4 cases of GP were obtained through the medical record inquiry from January 2011 to December 2017 at the First Affiliated Hospital of Zhengzhou University. Routine HE staining and immunohistochemistry of CKpan, Syn, CgA, CD56, NSE and NF were performed. Clinical follow-up of the patients was obtained through telephone communication. Results: All 4 patients, including 2 male and 2 female patients, presented with intermittent abdominal pain and distention. The median age was 56 years. Preoperative CT showed local thickening of the duodenum wall with slight enhancement in all four cases. Endoscopic ultrasonography showed low level echo in the mucous layer and submucosa involved by the tumor in 3 of 4 cases. The maximal diameter of the tumor ranged from 0.6 to 1.8 cm with an average of 1.2 cm. Microscopically, the tumors consisted of epithelioid, spindle and ganglion-like cells, and the proportion of the three cell types was different among cases. Epithelioid cells expressed CKpan, Syn, CgA and CD56. Spindle cells expressed S-100 protein and SOX-10 and ganglion-like cells expressed NF, Syn, CgA and CD56.All tumour cells expressed NSE. All 4 patients had no recurrence a post-surgery follow-up period of 3 to 30 months. Conclusions: GP of the duodenum is a benign tumor with excellent prognosis after endoscopic excision. Although its incidence is very low, its diagnosis should be considered for any mass lesion of the duodenum, especially involving mucosa and submucosa of the second dudenal segment.

Abstract
Objective: To investigate the value of spectral CT-based quantitative analysis in the differential diagnosis of liver cancer and liver abscess. Methods: A total of 70 patients with space-occupying lesions in the liver(45 with liver cancer and 25 with liver abscess)underwent spectral CT scans to obtain spectral images in the arterial phase and portal venous phase. The solid constituents of lesions and the iodine and water concentrations in necrotic or cystic parts of lesions, normal hepatic tissue, and abdominal aorta in the arterial phase and portal venous phase were measured, and the normalized iodine concentration(NIC)and lesion-to-normal hepatic tissue ratio(LNR)of iodine concentration were calculated. The two samples t-test and the receiver operating characteristic(ROC)curve analysis were performed for the quantitative indices above. Results: The patients with liver cancer had higher NIC and LNR in solid constituents in the arterial phase than those with liver abscess(NIC: 0.15±0.06 mg/ml vs 0.14±0.02 mg/ml, P > 0.05; LNR: 2.78±0.65 vs 1.45±0.88, P < 0.001). The patients with liver abscess had significantly higher NIC and LNR in solid constituents in the portal venous phase than those with liver cancer(NIC: 0.65±0.08 mg/ml vs 0.52±0.08 mg/ml, P≤0.001; LNR: 1.22±0.23 vs 0.95±0.15, P≤0.001). There were no significant differences in NIC in the arterial phase or NIC and LNR in the portal venous phase in necrotic or cystic parts of lesions between the patients with liver cancer and liver abscess(P > 0.05). The optimal quantitative value for the differential diagnosis of liver cancer and liver abscess was LNR in arterial phase, and the cut-off value of 1.53 had a sensitivity of 100% and a specificity of 92%. Conclusion: Quantitative iodine concentration analysis in spectral CT imaging has a certain value in the differential diagnosis of liver cancer and liver abscess and can improve the accuracy of diagnosis.

Abstract
The aim of this study was to characterize variations in Raf kinase inhibitor protein (RKIP) expression and related signaling molecules in gastric cardia adenocarcinoma. Cancerous and precancerous tissues were collected from patients with gastric cardia adenocarcinoma and normal tissue was collected from healthy controls. RKIP expression was detected in these tissues and the serum levels of NF-κB p65 and T-lymphocyte subsets were measured. Positive RKIP expression was higher in gastric cardia adenocarcinoma tissues than in precancerous tissues. The serum level of total NF-κB p65 was higher in patients with gastric cardia adenocarcinoma than in healthy controls. Levels of NF-κB p65 did not correlate with positive and negative expression of RKIP, but were higher in patients with lymph node metastasis than in those without it. The cellular immune function of the gastric cardia adenocarcinoma group was lower than in normal controls, particularly in cases with negative RKIP expression. RKIP is downregulated in gastric cardia adenocarcinoma tissues, which is related to the occurrence, progression, invasion, and metastasis of tumors. The possible mechanism for this may be the inhibition of NF-κB activity and cellular immune function, which allows for the escape of tumor cells from immune surveillance.

Abstract
Physical localization of molecular markers and assignment of the 15th linkage group to chromosome 11 of the karyotype in cassava (Manihot esculenta Crantz) were achieved using primed in situ labeling. Amplified signals for both the EST507-1 and SSRY13-5 markers were consistently observed in different stages of cell division. A comparison of the length, arm ratio, and other morphological characteristics of somatic metaphase chromosomes in karyotype analysis indicated that the EST507-1 and SSRY13-5 markers were localized on the short and long arm of cassava chromosome 11 with the relative map positions of 41.67 and 23.07, respectively. The physical localization of the 2 markers on chromosome 11 of the karyotype corresponds to their positions on the 15th linkage group in cassava.

Abstract
PURPOSE Efficient tumor volume delineation by the combined use of PET/CT scanning is necessary for the proper treatment of non-small cell lung cancer (NSCLC). To understand the effect of variation in background intensity on PET-based gross tumor volume (GTV) delineation, we determined the background standard uptake values (SUVs) in normal lung, aorta (blood pool), and liver tissues and determined GTVs using different methods. METHODS Thirty-seven previously untreated patients with pathologically confirmed NSCLC underwent PET/CT scanning with (18)F-fluorodeoxyglucose ((18)F-FDG). To obtain (18)F-FDG uptake values in normal tissues, regions of interest in the lung lobes (left upper, left lower, right upper, right middle, and right lower), aorta, and liver zones (left, intermediate, and right) were measured. The coefficient of variation (CV) of the SUV was measured for each normal structure. The CT-based GTV (GTV(CT)) was considered as the standard to which all PET-based GTVs were compared, and the correlation coefficient was analyzed to compare GTV obtained by the various delineation methods. Linear and logarithmic regression analyses were used to determine the relationship between GTV(CT) and GTV(PET). RESULTS Normal lung tissue showed a significantly lower SUV and less stability than tissue of the aorta or liver. For the lung, aorta, and liver, the maximum SUV (SUV(max)) was 0.82 ± 0.32, 2.35 ± 0.37, and 3.24 ± 0.50 (CV: 38.79%, 15.82%, and 15.30%) and average SUV (SUV(ave)) was 0.49 ± 0.18, 1.68 ± 0.32, and 2.34 ± 0.36 (CV: 36.38%, 18.92%, and 15.44%), respectively. The SUVs of the lung varied from lobe to lobe. The GTV delineation method using the SUV(ave) of the lung lobe in which the tumor was found as background in the source-to-background ratio (SBR) method showed the best correlation with the volume of CT-based GTV (r=0.81). CONCLUSIONS Our results show vast variation in the SUV among normal tissues, as well as in the different lung lobes. The tumor volume delineated using the SBR method correlated well with the CT-based tumor volume. We conclude that it is reasonable and precise to contour GTV in patients with NSCLC after taking into account the background intensity of the lung lobe in which the tumor is found.

Abstract
OBJECTIVES In this study, we investigated the effect of grape seed proanthocyanidins extracts (GSPE), which have been proved to have anti-oxidative and anti-aging functions, on the expression of apoA-L at mRNA level of HepG2 cells in vitro under the experimental conditions of high-sugar and sugar. MATERIALS AND METHODS Cell viability was measured by sulforhodamine B (SRB). The apoA-I mRNA expression was assayed by real-time fluorescence quantitative polymerase chain reaction. Firstly, HepG2 cells were incubated in 10% inactivated newborn calf serum in Dulbecco's Modified Eagle Medium (DMEM). Next, cells were incubated with high-sugar and sugar serum-free medium, and added different concentration of GSPE (2.5, 5 and 10 microg/ml) for more than 24 hours, and thereafter, investigated whether GSPE can promote more apoA-I expression in HepG2 cells under the experimental conditions of high-sugar and sugar. RESULTS In this experiment, HepG2 cells were incubated with high-sugar and sugar serum-free medium, and HepG2 cells incubated with high-sugar medium produced less apoA-I at mRNA level. The difference was significant (p < 0.05). When HepG2 cells were incubated with GSPE at concentration of 20 microg/ml or above for about 4 hours, cell viability measured by SRB was lower than 50%. However, cell viability of HepG2 cells incubated with GSPE at concentration of 10 microg/ml or below was higher than 70%. Therefore, we chose the HepG2 cells incubated with GSPE concentration of 2.5, 5, 10 microg/ml to observe the effect of GSPE on the mRNA expression of apoA-I. After incubated with GSPE, the apoA-I expression of HepG2 cells were significantly elevated at mRNA level compared to that of high sugar control (p < 0.05). Moreover, this action of GSPE showed dose dependent, and the dose of 2.5 microg/ml was optimal. CONCLUSIONS GSPE (concentration of higher than 20 microg/ml) could inhibit HepG2 cell survival, and in HepG2 cells, endogenous apoA-I was significantly suppressed following 24h of exposure to high concentrations of glucose. Meanwhile GSPE could promote expression of apoA-L dose dependently at mRNA level when its concentration was lower than 10 microg/ml.

Abstract
Increasing evidence has indicated the important roles of inflammation and immune response in the development of atherosclerosis and ischemic heart disease (IHD). We measured the serum interleukin (IL)-8 and IL-12 levels of patients with unstable angina pectoris (UAP) and patients with acute myocardial infarction (AMI), and compared findings with those of normal subjects. The results showed that the serum level of IL-8 was significantly higher in patients with UAP and patients with AMI than in healthy control subjects. To our knowledge, this is the first report that serum IL-12 level was elevated in patients with AMI but not in patients with UAP. These findings suggest that IL-8 and IL-12 are involved in the process of IHD, and serum IL-12 may be a marker for differentiating AMI from UAP.

Abstract
The synthesis of retroviral DNA is initiated near the 5' end of the RNA. DNA synthesis is transferred from the 5' end to the 3' end of viral RNA in an RNase H-dependent step. In the case of human immunodeficiency virus type 1 (HIV-1) (and certain other retroviruses that have complex secondary structures at the ends of the viral RNA), there is the possibility that DNA synthesis can lead to a self-priming event that would block viral replication. The extent of RNase H cleavage must be sufficient to allow the strand transfer reaction to occur, but not so extensive that self-priming occurs. We have used a series of model RNA substrates, with and without a 5' cap, to investigate the rules governing RNase H cleavage at the 5' end of the HIV-1 genome. These in vitro RNase H cleavage reactions produce an RNA fragment of the size needed to block self-priming but still allow strand transfer. The cleavages seen in vitro can be understood in light of the structure of HIV-1 reverse transcriptase in a complex with an RNA/DNA substrate.

Abstract
When human immunodeficiency virus type 1 (HIV-1) is selected for resistance to 3TC, the methionine normally present at position 184 is replaced by valine or isoleucine. Position 184 is the X of the conserved YXDD motif; positions 185 and 186 form part of the triad of aspartic acids at the polymerase active site. Structural and biochemical analysis of 3TC-resistant HIV-1 reverse transcriptase (RT) led to a model in which a beta-branched amino acid at position 184 would act as a steric gate. Normal deoxynucleoside triphosphates (dNTPs) could still be incorporated; the oxathiolane ring of 3TCTP would clash with the beta branch of the amino acid at position 184. This model can also explain 3TC resistance in feline immunodeficiency virus and human hepatitis B virus. However, it has been reported (14) that murine leukemia viruses (MLVs) with valine (the amino acid present in the wild type), isoleucine, alanine, serine, or methionine at the X position of the YXDD motif are all resistant to 3TC. We prepared purified wild-type MLV RT and mutant MLV RTs with methionine, isoleucine, and alanine at the X position. The behavior of these RTs was compared to those of wild-type HIV-1 RT and of HIV-1 RT with alanine at the X position. If alanine is present at the X position, both MLV RT and HIV-1 RT are relatively resistant to 3TCTP in vitro. However, the mutant enzymes were impaired relative to their wild-type counterparts; there appears to be steric hindrance for both 3TCTP and normal dNTPs.

Abstract
Escherichia coli RNase H has a basic extension that is involved in binding nucleic acid substrates. This basic extension is present in the RNase H of Moloney murine leukemia virus reverse transcriptase (MLV RT), but has been deleted from the RNase H of HIV-1 RT. Previous work showed that removing the basic loop from MLV RT (the mutant is called DeltaC) blocked viral replication; however, DeltaC MLV RT retained RNase H activity in an in situ gel assay. We prepared recombinant DeltaC MLV RT and compared its activity to wild-type MLV RT. The DeltaC mutant is impaired in both polymerase and RNase H activity; the pattern of defects suggests that the basic loop is involved in the binding of MLV RT to a heteropolymeric template-primer.

Abstract
Treating HIV infections with drugs that block viral replication selects for drug-resistant strains of the virus. Particular inhibitors select characteristic resistance mutations. In the case of the nucleoside analogs 3TC and FTC, resistant viruses are selected with mutations at amino acid residue 184 of reverse transcriptase (RT). The initial change is usually to M184I; this virus is rapidly replaced by a variant carrying the mutation M184V. 3TC and FTC are taken up by cells and converted into 3TCTP and FTCTP. The triphosphate forms of these nucleoside analogs are incorporated into DNA by HIV-1 RT and act as chain terminators. Both of the mutations, M184I and M184V, provide very high levels of resistance in vivo; purified HIV-1 RT carrying M184V and M184I also shows resistance to 3TCTP and FTCTP in in vitro polymerase assays. Amino acid M184 is part of the dNTP binding site of HIV-1 RT. Structural studies suggest that the mechanism of resistance of HIV-1 RTs carrying the M184V or M184I mutation involves steric hindrance, which could either completely block the binding of 3TCTP and FTCTP or allow binding of these nucleoside triphosphate molecules but only in a configuration that would prevent incorporation. The available kinetic data are ambiguous: one group has reported that the primary effect of the mutations is at the level of 3TCTP binding; another, at the level of incorporation. We have approached this problem using assays that monitor the ability of HIV-1 RT to undergo a conformational change upon binding a dNTP. These studies show that both wild-type RT and the drug-resistant variants can bind 3TCTP at the polymerase active site; however, the binding to M184V and M184I is somewhat weaker and is sensitive to salt. We propose that the drug-resistant variants bind 3TCTP in a strained configuration that is salt-sensitive and is not catalytically competent.

Abstract
Retroviral revXerse transcriptases (RTs) have an associated RNase H activity that can cleave RNA-DNA duplexes with considerable precision. We believe that the structure of the RNA-DNA duplexes in the context of RT determines the specificity of RNase H cleavage. To test this idea, we treated three related groups of synthetic RNA-DNA hybrids with either Moloney murine leukemia virus (MLV) RT or human immunodeficiency virus type 1 (HIV-1) RT. All of the hybrids were prepared using the same 81-base RNA template. The first series of RNase H substrates was prepared with complementary DNA oligonucleotides of different lengths, ranging from 6 to 20 nucleotides, all of which shared a common 5' end and were successively shorter at their 3' ends. The second series of oligonucleotides had a common 3' end but shorter 5' ends. The DNA oligonucleotides in the third series were all 20 bases long but had non-complementary stretches at either the 5' end, 3' end, or both ends. Several themes have emerged from the experiments with these RNA-DNA duplexes. (1) Both HIV-1 RT and MLV RT cleave fairly efficiently if the duplex region is at least eight bases long, but not if it is shorter. (2) Although, under the conditions we have used, both enzymes require the substrate to have a region of RNA-DNA duplex, both MLV RT and HIV-1 RT can cleave RNA outside the region that is part of the RNA-DNA duplex. (3) The polymerase domain of HIV-1 RT uses certain mismatched segments of RNA-DNA to position the enzyme for RNase H cleavage, whereas the polymerase domain of MLV RT does not use the same mismatched segments to define the position for RNase H cleavage. (4) For HIV-1 RT, a mismatched region near the RNase H domain can interfere with RNase H cleavage; cleavage is usually (but not always) more efficient if the mismatched segment is deleted. These results are discussed in regard to the structure of HIV-1 RT and the differences between HIV-1 RT and MLV RT.

Abstract
Based on structural analyses and on the behavior of mutants, we suggest that the polymerase domain of HIV-1 reverse transcriptase (RT) plays a critical role in holding and appropriately positioning the template-primer both at the polymerase active site and at the RNase H active site. For RT to successfully copy the viral RNA genome, RNase H must cleave the RNA with absolute precision. We believe that a combination of the structure of the template-primer and its precise positioning are responsible for the specific cleavages RNase H makes. We have proposed that resistance of HIV-1 RT to nucleoside analogs involves a subtle repositioning of the template-primer. This hypothesis is based on both structural and biochemical analyses. Mutations that confer resistance to nucleoside analogs do not cluster at the polymerase active site; however, they are in positions where they could alter the interaction between RT and the template-primer. If, as we have hypothesized, the polymerase domain is primarily responsible for positioning the template-primer and RNase H cleavage depends on this positioning, it should be possible to use RNase H cleavage to monitor at least some of the major changes in the position of the template-primer. We have used three assays (polymerase, RNase H, and strand transfer) to investigate the effects of mutations in the polymerase domain, including mutations that confer resistance to nucleotide analogs, on HIV-1 RT. All three assays involve RNA sequences derived from the viral genome. The data show that alterations in the polymerase domain, in particular, mutations that are in positions that would be expected to alter the interaction of RT with the template-primer, can alter both the efficiency and specificity of RNase H cleavage. These results are discussed in light of the structure of HIV-1 RT.

Abstract
To investigate whether circadian or any other temporal pattern(s) exist in the occurrence of acute myocardial infarction (AMI) in a Chinese population, we analyzed 428 patients with confirmed AMI for temporal patterns of AMI occurrence. The patients admitted to the Affiliated Hospital of Shandong Medical University during 1991-95 were from Jinan, the capital city of Shandong Province of China, which has a population of 2.5 million. The chi-square test for goodness of fit was used to test the difference among the frequencies of AMI occurrence in 4 equal intervals (01.00-07.00 h, 07.00-13.00 h, 13.00-19.00 h, 19.00-01.00 h) during the day and among those on 7 days during the week. The results showed that AMI occurrence exhibited significant circadian (p<0.001) and septadian (day of the week) (p=0.046) periodicity, with a peak at 01.00-07.00 h and a trough at 13.00-19.00 h during the day, and a peak on Saturday and a trough on Wednesday during the week. The peak to trough ratio of risk was 2.7 during the day and 2.1 during the week. It is concluded that there were circadian and septadian biorhythms in AMI occurrence in the Chinese population and that these were different from those observed in Western populations. Further investigation of the underlying mechanisms may shed further light on the trigger mechanisms of AMI and thus be helpful in the prevention and treatment of AMI.

Abstract
We have analyzed amino acid substitutions at position G190 in the reverse transcriptase (RT) of human immunodeficiency virus type 1 (HIV-1). The mutation G190E, which is responsible for resistance to certain nonnucleoside inhibitors, results in RT that has significantly less polymerase activity and that is less processive than wild-type RT. Its kinetic profile with respect to dGTP and poly(rC).oligo(dG) is significantly altered compared to that of wild-type RT. The combination of either of the mutations L74V or V75I with the G190E mutation appears to be compensatory and mitigates many of the deleterious effects of the G190E mutation.

Abstract
Treatment of human immunodeficiency virus type 1 reverse transcriptase (HIV-1 RT) with N-ethylmaleimide (NEM) selectively inhibits the RNase H activity. The cysteine residue at position 280 (C280) is the target for NEM; HIV-1 RT carrying the mutation C280S is resistant to NEM. Since HIV-1 RT is composed of two related subunits (p66 and p51) that play distinct roles, we asked whether the C280 in p51 or the C280 in p66 is responsible for the sensitivity of the enzyme to NEM. HIV-1 RT versions were prepared that had one mutant and one wild-type subunit. When these chimeric enzymes were tested, both the p51 and p66 subunits were found to contribute to the sensitivity of the enzyme to NEM. The implications of these results are discussed in the context of the structure of the enzyme.
