| 3 | Chronic exposure to excess iron promotes EMT and cancer via p53 loss in pancreatic cancer显示文摘Based on the evidence that hemochromatosis, an iron-overload disease, drives hepatocellular carcinoma, we hypothesized that chronic exposure to excess iron, either due to genetic or environmental causes, predisposes an individual to cancer. Using pancreatic cancer as our primary focus, we employed cell culture studies to interrogate the connection between excess iron and cancer, and combined in vitro and in vivo studies to explore the connection further. Ferric ammonium citrate was used as an exogenous iron source. Chronic exposure to excess iron induced epithelial-mesenchymal transition(EMT) in normal and cancer cell lines, loss of p53, and suppression of p53 transcriptional activity evidenced from decreased expression of p53 target genes(p21, cyclin D1, Bax, SLC7A11). To further extrapolate our cell culture data, we generated EL-KrasG12D( EL-Kras) mouse(pancreatic neoplastic mouse model) expressing Hfe+/+ and Hfe-/- genetic background. p53 target gene expression decreased in EL-Kras/Hfe-/- mouse pancreas compared to EL-Kras/Hfe+/+ mouse pancreas. Interestingly, the incidence of acinar-to-ductal metaplasia and cystic pancreatic neoplasms(CPN) decreased in EL-Kras/Hfe-/- mice, but the CPNs that did develop were larger in these mice than in EL-Kras/Hfe+/+ mice. In conclusion, these in vitro and in vivo studies support a potential role for chronic exposure to excess iron as a promoter of more aggressive disease via p53 loss and SLC7A11 upregulation within pancreatic epithelial cells. | Yangzom D.Bhutia Jiro Ogura Paul J.Grippo Carolina Torres Toshihiro Sato Mitchell Wachtel Sabarish Ramachandran Ellappan Babu Sathish Sivaprakasam Devaraja Rajasekaran Bradley Schniers Nhu On Logan Smoot Muthusamy Thangaraju Jaya P.Gnana-Prakasam Vadivel Ganapathy | 2020 | Asian Journal of Pharmaceutical Sciences2020，15，2： | 1 |
| 4 | Evaluatingα-galactosylceramide as an adjuvant for live attenuated infuenza vaccines in pigs显示文摘Natural killer T(NKT)cells activated with the glycolipid ligandα-galactosylceramide(α-GalCer)stimulate a wide variety of immune cells that enhance vaccine-mediated immune responses.Several studies have used this approach to adjuvant inactivated and subunit infuenza A virus(IAV)vaccines,including to enhance cross-protective infuenza immunity.However,less is known about whetherα-GalCer can enhance live attenuated infuenza virus(LAIV)vaccines,which usually induce superior heterologous and heterosubtypic immunity compared to non-replicating infuenza vaccines.The current study used the swine infuenza challenge model to assess whetherα-GalCer can enhance cross-protective immune responses elicited by a recombinant H3N2 LAIV vaccine(TX98ΔNS1)encoding a truncated NS1 protein.In one study,weaning pigs were administered the H3N2 TX98ΔNS1 LAIV vaccine with 0,10,50,and 100μg/kg doses ofα-GalCer,and subsequently challenged with a heterologous H3N2 virus.All treatment groups were protected from infection.However,the addition ofα-GalCer appeared to suppress nasal shedding of the LAIV vaccine.In another experiment,pigs vaccinated with the H3N2 LAIV,with or without 50μg/kg ofα-GalCer,were challenged with the heterosubtypic pandemic H1N1 virus.Pigs vaccinated with the LAIV alone generated cross-reactive humoral and cellular responses which blocked virus replication in the airways,and signifcantly decreased virus shedding.On the other hand,combining the vaccine withα-GalCer reduced cross-protective cellular and antibody responses,and resulted in higher virus titers in respiratory tissues.These fndings suggest that:(i)high doses ofα-GalCer impair the replication and nasal shedding of the LAIV vaccine;and(ii)α-GalCer might interfere with heterosubtypic cross-protective immune responses.This research raise concerns that should be considered before trying to use NKT cell agonists as a possible adjuvant approach for LAIV vaccines. | Bianca L.Artiaga Igor Morozov Russell Ransburgh Taeyong Kwon Velmurugan Balaraman Sabarish V.Indran Darling Melany De Carvalho Madrid Weihong Gu Jamie Henningson Wenjun Ma Jürgen A.Richt John P.Driver | 2022 | Animal Diseases2022，2，4： | 0 |
