\n\nTake home message: Preclinical studies on Hsp90 inhibition in oesophageal cancer are promising and it is anticipated that in the near future clinical trials with Hsp90 inhibitors will be initiated also for oesophageal cancer, using the experience from other trials.”
“Chemokines and their receptors have been shown to play a vital role in lung cancer progression. D6 PD-1/PD-L1 Inhibitor 3 cost is an atypical chemokine receptor which is able to internalize and degrade chemokines. To investigate the potential role of D6 in lung cancer, we established D6-overexpressing A549 lung cancer cell. lines by the transfection of human D6 cDNA.
Results showed that D6 inhibited the proliferation of cancer cells in vitro and tumorigenesis in vivo. We also determined chemokine levels in the supernatant Bafilomycin A1 mouse and showed that a number of chemokines (CCL2/4/5) had significantly decreased protein levels in D6-overexpressing cells compared with the controls, whereas no significant changes in mRNA expression levels of these chemokines
were detected. The cell cycle distribution and expression of certain growth factors and their receptors did not change in the D6-overexpressing cell compared with parental cells. Thus, our results suggest that D6 is a negative regulator of growth in lung cancer, mainly by the sequestration of specific chemokines.”
“Background: The role of viruses in pediatric pneumonia remains poorly studied in sub-Saharan Africa, where pneumonia-associated mortality is high.\n\nMethods: During a 1-year hospital-based surveillance, a nasopharyngeal aspirate (NPA) was collected from children aged <5 years admitted to hospital in rural Mozambique with clinically severe pneumonia. Identification of 12 respiratory viruses was performed by polymerase chain reactions (PCR). Study children were also tested for invasive bacterial infection (IBI), Plasmodium falciparum parasitemia, and HIV.\n\nResults: Almost half (394/807) of the children hospitalized with clinically severe pneumonia had at least one respiratory virus detected. A IPI-145 concentration total of 475 viruses were detected among these 394 children, the most prevalent ones were
rhinovirus (41%), adenovirus (21%), and respiratory syncytial virus (11%). Eleven percent of viral infected children had concomitant IBI, 15% had malaria parasites, and 25% had HIV coinfection. Viral infection was 5.5 to 16 times more prevalent among HIV-infected children and incidence rate ratios varied according to virus. Inhospital mortality of viral cases was 9%, being highest among cases with IBI coinfection (odds ratio = 7) or HIV infection (odds ratio = 7).\n\nConclusions: Study results highlight the high prevalence of respiratory viruses among hospitalized pneumonia cases in Mozambique. HIV infection is an important contributor to the high burden of disease and associated mortality of viral pneumonia. IBI also contributes to a worse prognosis of viral cases.
