In this study, products of psoralen pyrolysis were detected using a solid pyrolysis apparatus and synchrotron radiation vacuum ultraviolet photoionization mass spectrum (SVUV-PIMS). The pyrolytic kinetics of psoralen was also studied by calculating its initial pyrolytic route in quantum chemistry. According to the findings with SVUV-PIMS, three pyrolytic products were observed, CO, C9H6O and C10H6O2. Theoretically, three fragment pathways were calculated for psoralen, in which the major primary decomposition route was de-CO, and the major secondary decomposition reaction was de-CO reaction of de-CO products.

OBJECTIVETo validate the difference on the prevalence of rheumatic symptoms between north and south parts of the country and to study the associated risk factors of rheumatic complaints in Shantou city, China.

METHODSA total number of 10 638 people at above 16 years of age from four samples, were surveyed in 1987, 1992, 1995, and 1999. Protocol of International League Against Rheumatism (ILAR)-China collaborative study or WHO-ILAR community oriented program for control of rheumatic disease(COPCORD) core questionnaire was implemented. Data on related rheumatic symptoms were collected and analyzed.

RESULTSThe prevalence rate of rheumatic complaints had been increasing in Shantou area during the last decade (in 1987 11.6%, 1992 12.5%, 1995 16.0% and 1999 19.8%) but still lower than that seen in Beijing, China in 1987(40.0%). Rheumatic symptoms were more prevalent in females than in males, in elderly than in young people with most frequently involved site happened in low back area, followed by knee and neck. Lumbar pain was more frequent among rural residents, while neck pain was more prevalent in urban school students. Prevalence of knee pain was significantly higher in people living in multi-storey buildings without elevator than those living in single-storey houses. The peak values of Bone Mineral Density in Shantou population were (0.839 +/- 0.085) g/cm2 in men, and (0.723 +/- 0.064) g/cm2 in women, significantly higher than that reported in 13 other provinces and cities including Beijing. The sense of seeking for medical help was higher in population with higher prevalence of rheumatic symptoms than that in lower complaints group. However, no significant difference was found in the rates of disability among the different populations.

CONCLUSIONThe prevalence rate of rheumatic complaints was lower in Shantou than that in Beijing. Socio-economic status, environment, sex, age, occupation, ergonomics, bone mineral density, and awareness of seeking medical care might have been the associated risk factors to the prevalence of rheumatic complaints.

In this study, the synthetic pathway of β-amyrin was constructed in the pre-constructed Saccharomyces cerevisiae chassis strain Y0 by introducing β-amyrin synthase from Glycyrrhiza uralensis, resulting strain Y1-C20-6, which successfully produced β-amyrin up to 5.97 mg·L~(-1). Then, the mevalonate pyrophosphate decarboxylase gene(ERG19), mevalonate kinase gene(ERG12), 3-hydroxy-3-methylglutaryl-CoA synthase gene(ERG13), phosphomevalonate kinase gene(ERG8) and IPP isomerase gene(IDI1)were overexpressed to promoted the metabolic fluxto the direction of β-amyrin synthesis for further improving β-amyrin production, resulting the strain Y2-C2-4 which produced β-amyrin of 10.3 mg·L~(-1)under the shake flask fermentation condition. This is 100% higher than that of strain Y1-C20-6, illustrating the positive effect of the metabolic engineering strategy applied in this study. The titer of β-amyrin was further improved up to 157.4 mg·L~(-1) in the fed-batch fermentation, which was almost 26 fold of that produced by strain Y1-C20-6. This study not only laid the foundation for the biosynthesis of β-amyrin but also provided a favorable chassis strain for elucidation of cytochrome oxidases and glycosyltransferases of β-amyrin-based triterpenoids.

In this study, citrate synthase gene(CIT2), and malate synthase gene(MLS1) were successfully knocked out in β-amyrin-producing yeast cells by using CRISPR/CAS9. The promoter of phosphoglucose isomerase gene(PGI1) was replaced by that of cytochrome c oxidase subunit Ⅶa(Cox9)to weaken its expression, aiming to channel more carbon flux into the NADPH-producing pathway. The fermentation results showed that CIT2 deletion had no effect on the β-amyrin production. Compared with the control strain, the production of β-amyrin was increased by 1.85 times after deleting MLS1, reaching into 3.3 mg·L~(-1). By replacing the promoter of PGI1, the β-amyrin yield was 3.75 times higher than that of the control strain, reaching up to 6.7 mg·L~(-1). This study successfully knocked out the CITT2 and MLS1 genes and weakened the PGI1 gene by using CRISPR/CAS9, which directly influenced the production of β-amyrin and provided some reference for the the metabolic engineering of triterpernoid producing strain.

BACKGROUND: Bladder cancer, characterized by a high potential of tumor recurrence, has high lifelong monitoring and treatment costs. To date, tumor cells with intrinsic softness have been identified to function as cancer stem cells in several cancer types. Nonetheless, the existence of soft tumor cells in bladder tumors remains elusive. Thus, our study aimed to develop a micro-barrier microfluidic chip to efficiently isolate deformable tumor cells from distinct types of bladder cancer cells. METHODS: The stiffness of bladder cancer cells was determined by atomic force microscopy (AFM). The modified microfluidic chip was utilized to separate soft cells, and the 3D Matrigel culture system was to maintain the softness of tumor cells. Expression patterns of integrin β8 (ITGB8), protein kinase B (AKT), and mammalian target of rapamycin (mTOR) were determined by Western blotting. Double immunostaining was conducted to examine the interaction between F-actin and tripartite motif containing 59 (TRIM59). The stem-cell-like characteristics of soft cells were explored by colony formation assay and in vivo studies upon xenografted tumor models. RESULTS: Using our newly designed microfluidic approach, we identified a small fraction of soft tumor cells in bladder cancer cells. More importantly, the existence of soft tumor cells was confirmed in clinical human bladder cancer specimens, in which the number of soft tumor cells was associated with tumor relapse. Furthermore, we demonstrated that the biomechanical stimuli arising from 3D Matrigel activated the F-actin/ITGB8/TRIM59/AKT/mTOR/glycolysis pathways to enhance the softness and tumorigenic capacity of tumor cells. Simultaneously, we detected a remarkable up-regulation in ITGB8, TRIM59, and phospho-AKT in clinical bladder recurrent tumors compared with their non-recurrent counterparts. CONCLUSIONS The ITGB8/TRIM59/AKT/mTOR/glycolysis axis plays a crucial role in modulating tumor softness and stemness. Meanwhile, the soft tumor cells become more sensitive to chemotherapy after stiffening, that offers new insights for hampering tumor progression and recurrence.
