The aim of this study was to explore the regulatory mechanism of Type Ⅲ domain-containing protein5 (FNDC5) on adipogenic differentiation in C3H10T1/2 cells. qRT-PCR and Western blot were used to detect the expression of FNDC5 during adipogenic differentiation of C3H10T1/2 cells. The lentivirus-coated overexpression and interference vector of FNDC5 were constructed and transfected into C3H10T1/2 cells. qRT-PCR was used to detect the expression of the key genes of adipogenic differentiation. Oil red O staining was used to detect the formation of lipid droplets; Western blot was used to detect the content of ERK1/2 and ERK1/2 phosphorylated protein (P-ERK1/2). After 8 days of adipogenic differentiation of C3H10T1/2 cells, the expression of Fndc5 increased significantly. After overexpression of FNDC5 in C3H10T1/2 cells, the expression of key genes for adipogenic differentiation, including peroxisome proliferator-activated receptor-酌 (PPAR酌), CCAAT enhancer binding protein beta (C/EBP茁), fatty acid binding protein 4 (FABP4) and CCAAT enhancer binding protein alpha (C/EBPα), all decreased significantly. The content of lipid droplets and P-ERK1/2 also decreased significantly. On the contrary, after interference of FNDC5 in C3H10T1/2 cells, the expression of key genes for adipogenic differentiation, including PPARγ, C/EBP茁, FABP4 and C/EBPα were significantly increased. Meanwhile, the content of lipid droplets and P-ERK1/2 also increased significantly. This study found that FNDC5 can inhibit the adipogenic differentiation of C3H10T1/2 cells by inhibiting the phosphorylation level of ERK1/2, which can provide reference data for the mechanism of FNDC5 in regulating fat deposition.

The objective of this study was to investigate the expression profile of the myozenin2 (MYOZ2) gene and elucidate its effect on adipogenic differentiation of C3H10T1 / 2 cells and its possible mechanism∙ The longissimus dorsi‚ subcutaneous fat and liver tissue was collected from 180-day-old Mashen pigs‚ 60-day-old ICR mice‚ 35-day-old Ross broiler and 12-month-old Small tail han sheep‚ and the expression profile of the MYOZ2 gene mRNA was detected∙ The results showed that the MYOZ2 gene has similar patterns of tissue expression in examined species‚ with the highest expression level in longissimus dorsi‚ and a small amount of expression in the subcutaneous fat and liver tissue∙ After the MYOZ2 gene was silenced in C3H10T1 / 2 cells‚ qRT-PCR results showed that the expression levels of key adipogenic genes PPARγ and FABP4 were significantly down-regulated compared with the control group (P < 0∙ 01) ; Western Blotting results showed that the PPARγ protein content was significantly decreased (P < 0∙ 05) ; Oil red O staining showed that the number of lipid droplets and the content of triglyceride were significantly decreased after silencing MYOZ2 (P < 0∙ 05) ∙ The expression of fatty acid metabolism related genes SCD‚ FASN‚ SREBP1‚ NR1H3‚ DGAT1‚ PNPLA2‚ HSL‚ CES1‚ CPT1 after MYOZ2 silencing were detected by qRT-PCR∙ The results showed that SCD‚ FASN‚ SREBP1‚ PNPLA2 and HSL were significantly down-regulated (P < 0∙ 01) ‚ NR1H3 was significantly reduced (P < 0∙ 05) ‚ DGAT1 expression was down-regulated but the difference was not significant‚ CES1 and CPT1 were significantly up-regulated (P < 0∙ 05) ∙ The STRING database was used to construct a MYOZ2-related protein interaction network map‚ and it was found that MYOZ2 may affect the adipogenic differentiation through the interaction of titin-cap (TCAP) and PPARγ∙ After silencing TCAP‚ qRT-PCR results showed that compared with the control group‚ the expression of key adipogenic genes PPARγ and FABP4 were significantly up-regulated (P < 0∙ 01) ; Western Blotting results showed that PPARγ protein was significantly increased (P< 0∙ 05) ; Oil red O staining showed that the number of lipid droplets and the content of triglyceride were significantly increased after TCAP silencing (P < 0∙ 05) ∙ qRT-PCR was used to detect the expression of TCAP after silencing MYOZ2‚ and the results showed that the expression of TCAP was significantly increased (P<0∙ 01) ∙ In summary‚ MYOZ2 was highly expressed in longissimus dorsi and lower expressed in subcutaneous fat and liver tissues∙ In addition‚ MYOZ2 may regulate the expression of key adipogenic genes PPARγ and FABP4 through the interaction of MYOZ2-TCAP -PPARγ‚ and to further regulate the expression of fatty acid metabolism related genes SCD‚ FASN‚ SREBP1‚ NR1H3‚ DGAT1‚ PNPLA2‚ HSL‚ CES1 and CPT1‚ thus playing an important role in the process of adipogenic differentiation∙

Objective:To evaluate the effect of different doses of cisatracurium on the monitoring of motor-evoked potentials (MEPs) in the patients undergoing intracranial aneurysm clipping.Methods:Eighty patients of both sexes, aged 18-64 yr, with body mass index <30 kg/m 2, of American Society of Anesthesiologists physical statusⅠor Ⅱ, with Hunt-Hess grade 0-Ⅱ, undergoing intracranial aneurysm clipping under general anesthesia, were divided into 4 groups ( n=20 each) using a random number table method: conventional group (group R) and different doses of cis-atracurium groups (Cis 1-3 groups). After anesthesia induction, muscle relaxation was monitored, and train-of-four (TOF) stimulation (frequency 2 Hz, wave width 0.2 ms, interval 15 s) was applied to the ulnar nerve of forearm, and the TOF ratio was recorded as the baseline value (T 1). MEPs were assessed with a nerve electrophysiology monitor after induction of anesthesia.In Cis 1-3 groups, cis-atracurium 0.625, 0.833 and 1.000 μg·kg -1·min -1 were intravenously infused, while the equal volume of normal saline was given instead in group R when TOF ratio returned to the baseline value and MEPs could be effectively elicited.At T 1, immediately after dural incision (T 2), immediately after aneurysm occlusion (T 3) and immediately after dural closure (T 4), the TOF ratio, effective elicitation of intraoperative MEPs, and occurrence of intraoperative cardiovascular events, recovery of spontaneous breathing and body movement were recorded. Results:Compared with group R, no significant change was found in TOF ratio at each time point in group Cis 1 ( P>0.05), and TOF ratio was significantly decreased at T 2-4 in group Cis 2 and at T 2-4 in group Cis 3 ( P<0.05). Compared with group Cis 1, TOF ratio was significantly decreased at T 3, 4 in group Cis 2 and at T 2-4 in group Cis 3 ( P<0.05). The effective elicitation rate of MEPs was 100% in the four groups.There was no significant difference in the incidence of intraoperative cardiovascular events, recovery of spontaneous breathing and body movement among the four groups ( P>0.05). Conclusion:Continuous intravenous infusion of cis-atracurium 0.833-1.000 μg·kg -1·min -1 can maintain a certain degree of muscle relaxation without affecting MEP monitoring in the patients undergoing intracranial aneurysm clipping.

Rabies remains an important worldwide health problem. Newcastle disease virus (NDV) was developed as a vaccine vector in animals by using a reverse genetics approach. Previously, our group generated a recombinant NDV (LaSota strain) expressing the complete rabies virus G protein (RVG), named rL-RVG. In this study, we constructed the variant rL-RVGTM, which expresses a chimeric rabies virus G protein (RVGTM) containing the ectodomain of RVG and the transmembrane domain (TM) and a cytoplasmic tail (CT) from the NDV fusion glycoprotein to study the function of RVG's TM and CT. The RVGTM did not detectably incorporate into NDV virions, though it was abundantly expressed at the surface of infected BHK-21 cells. Both rL-RVG and rL-RVGTM induced similar levels of NDV virus-neutralizing antibody (VNA) after initial and secondary vaccination in mice, whereas rabies VNA induction by rL-RVGTM was markedly lower than that induced by rL-RVG. Though rL-RVG could spread from cell to cell like that in rabies virus, rL-RVGTM lost this ability and spread in a manner similar to the parental NDV. Our data suggest that the TM and CT of RVG are essential for its incorporation into NDV virions and for spreading of the recombinant virus from the initially infected cells to surrounding cells.

Antibody-drug conjugate (ADC) is a new class of therapeutics composed of a monoclonal antibody and small cytotoxin moieties conjugated through a chemical linker. ADC molecules bind to the target antigens expressed on the tumor cell surfaces guided by the monoclonal antibody component. The binding ADC molecules can be internalized and subsequently the toxin moieties can be released within the tumor cells via chemical and/or enzymatic reactions to kill the target cells. The conjugation combines the merits of both components, i.e., the high target specificity of the monoclonal antibody and the highly potent cell killing activity of the cytotoxin moieties. However, such complexities make the pharmacokinetic and metabolic studies of ADCs highly challenging. The major challenges should include characterization of absorption, distribution, metabolism and excretion, investigation of underlying mechanisms, assessment of pharmacokinetic- pharmacodynamic relationship, and analytical method development of ADC drugs. This review will discuss common pharmacokinetic issues and considerations, as well as tools and strategies that can be utilized to characterize the pharmacokinetic and metabolic properties of ADCs.

Objective To determine whether the combination of traditional risk factors and quantitative coronary angiography (QCA) assessment could provide accurate prognostic information on a population-based study including 1137 adults with subclinical artherosclerosis and with coronary risk factors. Methods Participants underwent coronary angiography examination before the minimal stenotic diameters, segment diameters, percent stenosis, plaque areas. Other parameters were analyzed by the computer-assisted Coronary Angiography Analysis System. The Framingham Risk Score for each participant was assessed. During the 1 year follow-up period, all kinds of endpoint cardiovascular events were screened. Endpoint events were defined as death from coronary heart disease, nonfatal myocardial infarction (MI) or unstable angina pectoris. Results During the 1 year of follow-up period, a total of 124 participants developed an endpoint event, which was significantly associated with the Framingham Risk Score, calcium of plaques and the plaque areas (all Ps＜0.05).The QCA score incorporated with the QCA parameters was related to the endpoint events. The Framingham Risk Score was combined with QCA score through logistic regression for prediction of end-point events. Data from the ROC analysis showed the accuracy of this prediction algorithm was superior to the accuracy when variables themselves were used. The event-free survival rate was inferior to the control group in participates under high risk, when being screened with this prediction algorithm (P＜0.05). Conclusion The risk of cardiovascular attack in subclinical artherosclerosis individual seemed to be associated with the Framingham Risk Score, calcium of plaques and the plaque areas. When the traditional risk factors (the Framingham Risk Score) were combined with QCA, the new method could provide more prognostic information on those adults with subclinical artherosclerosis.
