Question: Context: To elucidate the importance of hepatitis C Virus (HCV) genotype in HIV disease progression.', 'This study was conducted among 126 HIV/HCV co-infected drug users with a known interval of HIV seroconversion whose HCV genotype was known early in HIV infection. Both clinical progression (to AIDS) and immunological progression (to a CD4+ T-cell count of 200 x 10(6) cells/l) by HCV genotype were studied using Cox proportional hazards analysis.', 'The median duration of follow-up was 7.3 years [interquartile range (IQR), 4.6-10.1 years]. The majority of the HCV infections concerned genotype 1 and genotype 3; The distribution was: HCV type 1: 48%, HCV type 3: 34%, HCV type 4: 13%, multiple HCV types: 5%. Concurrent multiple infections consisted of HCV genotypes 1b+3a, 1b+4 and 3a+4. HCV genotype 1 and multiple HCV genotype infections were associated with faster immunological progression [hazard ratio (HR), 2.02; 95% confidence interval (CI), 1.04-3.92 and HR, 2.74; 95% CI, 0.95-7.90, respectively]. Multiple HCV genotype infection was also associated with faster clinical progression (HR, 3.36; 95% CI, 0.82-13.79). These hazard ratios increased further and were all significant when analyses were limited to data in the pre-HAART era (HR, 3.92; 95% CI, 1.51-10.20; HR, 4.38; 95% CI, 1.04-18.40 and HR, 6.54; 95% CI, 1.39-30.76, respectively).\Question: Is infection with concurrent multiple hepatitis C virus genotypes associated with faster HIV disease progression?

Answer: HIV disease progression differs by HCV genotype and is especially faster in individuals whose HCV infection involves more than one HCV genotype. The effect of HCV genotype on HIV progression was greater in the pre-highly active antiretroviral therapy (HAART) era, suggesting that the effectiveness of HAART may diminish the effect of HCV genotype on HIV disease progression.

Question: Context: Characteristic clinical heterogeneity and mostly slow-growing behavior of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) cause problems in finding appropriate treatments. Thus, current therapy options are not satisfactory. PKI-587 is a highly potent novel dual inhibitor of PI3K and mTORC1/C2.', 'We assessed the effects of PKI-587 in different GEP-NEN tumor models, including poorly differentiated cell line LCC-18, compared with the established mTORC1 inhibitor everolimus.', 'We treated the cell lines BON, QGP1, KRJ-I and LCC-18 with increasing concentrations of the inhibitor PKI-587, and compared with everolimus and DMSO. We assessed the impact of treatments on viability (WST-1 assay), on apoptotic processes (Caspase 3/7 assay, JC-1) and on cell cycle regulation (flow cytometry). We determined alterations of signaling mediators by phosphor-specific western blot analysis and conducted multiplexed gene expression analysis (nCounter®️ technology).', 'In all cell lines, PKI-587 dose-dependently inhibited proliferation whereas everolimus was less effective. Treatment with PKI-587 led to cell cycle arrest, induction of apoptosis and successfully suppressed activity of direct mTORC1 target 4E-BP1, a crucial factor for tumor genesis only partially inhibited by everolimus. Gene expression analyses revealed relevant changes of RAS, MAPK, STAT and PI3K pathway genes after treatment. Treatment dependent and cell line characteristic effects on AKT/RB/E2F signaling regarding cell cycle control and apoptosis are extensively discussed in this article.\Question: Is inhibition of mTORs Catalytic Site by PKI-587 a Promising Therapeutic Option for Gastroenteropancreatic Neuroendocrine Tumor Disease?

Answer: PI3K/mTOR dual targeting is a promising new therapeutic approach in neuroendocrine tumor disease that should be evaluated in further clinical trials.

Question: Context: It is evident that diabetes and periodontal disease are closely interrelated. Accumulation of advanced glycation end products (AGEs), coupled with exaggerated host responses to bacterial infection, may account for the increased periodontal destruction observed in patients with uncontrolled diabetes. The present study investigated the effects of AGEs on the viability of human gingival fibroblasts (HGFs) and the expression of types I and III collagen in HGFs.', 'The cell viability of HGFs was examined by methylthiazolet-etrazolium assay, whereas the expression of types I and III collagen message and protein was detected by real-time quantitative reverse transcription-polymerase chain reaction and sandwich enzyme-linked immunosorbent assay, respectively.', 'AGEs significantly suppressed the cell viability of HGFs from 24 to 72 hours (P <0.01). A high concentration of glucose (25 mmol/l) in the culture media exaggerated the inhibition of the survival rate of HGFs (P <0.01). The expression of collagen types I and III messages and proteins was significantly downregulated at 72 hours by AGEs in a concentration-dependent manner (P <0.05). Moreover, the synthesis of intracellular types I and III collagen protein was markedly inhibited by AGEs (P <0.05).\Question: Do advanced glycation end products inhibit the expression of collagens type I and III by human gingival fibroblasts?

Answer:
AGEs may suppress the cell viability of HGFs and downregulate the expression of types I and III collagen by the cells. Further investigations are warranted to clarify the molecular mechanisms of AGEs in the regulation of cell function and collagen metabolism in patients with diabetes and periodontitis.
