Background Although substantial evidence has shown that the mammalian target of rapamycin (mTOR) pathway is an important therapeutic target in gastric cancer, the overall response rates in patients to mTOR inhibitor everolimus have been less than initially expected. We hypothesized that the limited efficacy of everolimus in gastric cancer is due to the activation of extracellular signal-regulated kinase (ERK). Methods ERK activation was investigated using western blot. The effects of dual inhibition of ERK and mTOR via genetic and pharmacological approaches were determined using cellular assays and xenograft mouse model. Results We observed the decreased phosphorylation of mTOR, rS6, and 4EBP1 and increased phosphorylation of ERK and p90RSK in gastric cancer cells exposed to everolimus at clinically relevant concentration. see more Using both in vitro cell culture assays and in vivo xenograft mouse model, we found that trametinib overcame everolimus resistance by either effectively targeting resistant cells or further enhancing everolimus' efficacy in sensitive cells. Mechanism studies confirmed that trametinib overcame everolimus resistance via specifically inhibiting ERK and regulating ERK-mediated Bcl-2 family proteins in gastric cancer cells. Conclusions Inhibition of mTOR pathway can induce "paradoxical" activation of ERK in gastric cancer, and this activation can be reversed by trametinib. Since both drugs are clinically available, our findings might accelerate the initiation of clinical trials on gastric cancer using everolimus and trametinib combination.Clostridium acetobutylicum is a well-known strain for biofuel production. In previous work, it was found that this strain formed biofilm readily during fermentation processes. Biofilm formation could protect cells and enhance productivities under environmental stresses in our previous work. To explore the molecular mechanism of biofilm formation, Spo0A of C. acetobutylicum was selected to investigate its influences on biofilm formation and other physiological performances. When spo0A gene was disrupted, the spo0A mutant could hardly form biofilm. The aggregation and adhesion abilities of the spo0A mutant as well as its swarming motility were dramatically reduced compared to those of wild type strain. Sporulation was also negatively influenced by spo0A disruption, and solvent production was almost undetectable in the spo0A mutant fermentation. Furthermore, proteomic differences between wild type strain and the spo0A mutant were consistent with physiological performances. This is the first study confirming a genetic clue to C. acetobutylicum biofilm and will be valuable for biofilm optimization through genetic engineering in the future.Background Biliary atresia (BA) is an obstructive hepatobiliary disease which manifests during infancy. Kasai portoenterostomy (KPE) is the preferred operation for BA, supplemented with glucocorticoids, antibiotics, and choleretic agents. A great deal of research has been carried out regarding diagnosis, operation, and adjuvant therapies of BA, but no consensus had been reached. To understand the variation in diagnosis and treatment strategies of BA across mainland China and to help achieve a unified treatment strategy in the future, this investigation was carried out. Methods This investigation was conducted via electronic questionnaire. The centres were divided into three groups based on their annual caseload low (0-20)-, mid (21-40)-, and high (≥ 41)-volume group. Differences in the clinical practice among three groups were analyzed by Chi-square test and considered statistically significant at P 40 patients in 13 centres. Preoperative ultrasound and intraoperative cholangiography were performed in all ceelated to its caseload. In most centres, KPE is supplemented with glucocorticoids, antibiotics, and choleretic agents without a standard regimen.Purpose Individuals living with cancer have been shown to have a higher burden of comorbid disease and multimorbidity in comparison to their cancer-free counterparts consequently, leaving them at risk of polypharmacy (i.e., ≥ 5 medications) and its potential negative effects. The primary aim of the current study was to examine the self-reported prevalence of and association between multimorbidity and prescription medication use in a population-based sample of adult cancer survivors (CS). Methods This retrospective, nested case-control study drew participant data from the Atlantic Partnership for Tomorrow's Health cohort. CS (n = 1708) were matched to 4 non-cancer controls (n = 6832) by age and sex. Prevalence of polypharmacy by number of chronic conditions and age was estimated with 95% CI. Logistic regression was used to examine the association between multimorbidity and polypharmacy while adjusting for sociodemographic and lifestyle factors. The comorbidity-polypharmacy score was also calculated as an estimate of disease burden. Results Multimorbidity was common in both CS (53%) and non-cancer controls (43%); however, a significantly higher percentage of CS reported multimorbidity (p less then 0.001). Prescription medication use was also found to be significantly higher among CS (2.3 ± 2.6) compared to non-cancer controls (1.8 ± 2.3; p less then 0.0001). Exploratory comorbidity-polypharmacy score analyses indicated that CS had a significantly higher overall disease burden than the age/sex-matched non-cancer controls. Conclusions As CS appear to be at a higher risk of multimorbidity and polypharmacy and by extension, increased healthcare burden, ongoing education on the prevention of medication-related harm, and interventions to reduce the occurrence of both co-morbid disease and unnecessary medications are warranted.Despite significant progress made in the treatment of patients with multiple myeloma (MM) in the last decade, for patients with early relapse or rapidly progressing high-risk disease, allogeneic hematopoietic stem cell transplantation (SCT) might be an option leading to long-term survival. Here, we retrospectively analyzed the outcomes of 90 MM patients who received allogeneic SCT in our center between 1999 and 2017. We specifically assessed the association of impaired humoral immune reconstitution, referred to as immunoparesis, and post-transplant survival. Sixty-four patients received allogeneic SCT in relapse following 2-7 lines of therapy; 26 patients received upfront tandem autologous-allogeneic SCT. With a median follow-up of 76 months, OS and PFS were 52.6% (95% CI 42.9-64.3) and 36.4% (95% CI 27.6-47.9) at 2 years and 38.6% (95% CI 29.2-51.1) and 25.3% (95% CI 17.5-36.4) at 5 years, respectively. Receiving more than two therapy lines prior to transplantation was an independent risk factor for OS (HR 3.
