Abstract
Auto-antibodies against apoA-1 (anti-apoA-1 IgGs) have been identified as important actors of atherosclerosis development through pro-inflammatory and pro-atherogenic properties and to also induce apoptosis in tumoral neuronal and lymphocyte derived cell lines through unknown mechanisms. The purpose of this study was to explore the cellular pathways involved in tumoral cell survival modulated by anti-apoA-1 antibodies. We observed that anti-apoA-1 antibodies induce growth arrest (in G2/M phase) and cell apoptosis through caspase 3 activation, accompanied by a selective p53 phosphorylation on serine 15. RNA sequencing indicated that anti-apoA-1 IgGs affect the expression of more than 950 genes belonging to five major groups of genes and respectively involved in i) cell proliferation inhibition, ii) p53 stabilisation and regulation, iii) apoptosis regulation, iv) inflammation regulation, and v) oxidative stress. In conclusion, anti-apoA-1 antibodies seem to have a role in blocking tumoral cell proliferation and survival, by activating a major tumor suppressor protein and by modulating the inflammatory and oxidative stress response. Further investigations are needed to explore a possible anti-cancer therapeutic approach of these antibodies in very specific and circumscribed conditions.

Phylogenetically Distant Viruses Use the Same BH3-Only Protein Puma to Trigger Bax/Bak-Dependent Apoptosis of Infected Mouse and Human Cells. PLoS One 2015; 10:e0126645. [PMID: 26030884 PMCID: PMC4452691 DOI: 10.1371/journal.pone.0126645] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2015] [Accepted: 04/04/2015] [Indexed: 12/12/2022] Open
Abstract
Viruses can trigger apoptosis of infected host cells if not counteracted by cellular or viral anti-apoptotic proteins. These protective proteins either inhibit the activation of caspases or they act as Bcl-2 homologs to prevent Bax/Bak-mediated outer mitochondrial membrane permeabilization (MOMP). The exact mechanism by which viruses trigger MOMP has however remained enigmatic. Here we use two distinct types of viruses, a double stranded DNA virus, herpes simplex virus-1 (HSV-1) and a positive sense, single stranded RNA virus, Semliki Forest virus (SFV) to show that the BH3-only protein Puma is the major mediator of virus-induced Bax/Bak activation and MOMP induction. Indeed, when Puma was genetically deleted or downregulated by shRNA, mouse embryonic fibroblasts and IL-3-dependent monocytes as well as human colon carcinoma cells were as resistant to virus-induced apoptosis as their Bax/Bak double deficient counterparts (Bax/Bak-/-). Puma protein expression started to augment after 2 h postinfection with both viruses. Puma mRNA levels increased as well, but this occurred after apoptosis initiation (MOMP) because it was blocked in cells lacking Bax/Bak or overexpressing Bcl-xL. Moreover, none of the classical Puma transcription factors such as p53, p73 or p65 NFκB were involved in HSV-1-induced apoptosis. Our data suggest that viruses use a Puma protein-dependent mechanism to trigger MOMP and apoptosis in host cells.

Abstract
Lung cancer remains the leading cause of cancer-related mortality worldwide. Early detection of lung cancer is problematic due to the lack of a marker with high diagnosis sensitivity and specificity. To determine the differently expressed proteins in the serum of lung cancer and figure out the function of the proteins, two-dimensional electrophoresis (2DE) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) were used to screen the serum proteins of lung cancer model induced by 3-methylcholanthrene (MCA). From optimized 2DE image, 455 spots in the normal sera and 716 spots in the lung cancers sera were detected. Among them, 141 protein spots were differentially expressed when comparing the serum from normal rat and serum from lung cancer model, including 82 overexpressed proteins and 59 underexpressed proteins. Changes of haptoglobin, transthyretin, and TNF superfamily member 8 (TNFRS8) were confirmed in sera from lung cancer by MALDI-TOF-MS. Proteomics technology leads to identify changes of haptoglobin, transthyretin, and TNFRS8 in serum of rat lung cancer model and represents a powerful tool in searching for candidate proteins as biomarkers.

Abstract
Herpes simplex encephalitis (HSE) is the most common cause of non-epidemic, acute and fatal viral encephalitis. A pronounced mortality and morbidity remains in HSE despite antiviral treatment. There is evidence of a vigorous intrathecal immune activity in acute phases of HSE and of persistently increased activity at follow-ups after years. The role of apoptosis of neuronal cells in HSE patients as a mechanism of damage has been brought up lately. We hypothesize that the severity and the progression of the cerebral injury resulting from HSE can be evaluated by quantitative measurement of a compartment of immune activation molecules i.e. soluble Fas (sFas) involved in apoptosis through the Fas/Fas Ligand pathway. Consecutive cerebrospinal fluid (CSF) samples from a prospectively followed cohort, included in an antiviral treatment trial in HSE, were enrolled for quantitative measurement of sFas using commercial capture ELISA. In total, CSF samples from 49 patients with HSE, 63 patients with non-HSE encephalitis and 18 healthy individuals were studied. High levels of sFas were expressed in CSF samples collected between days 0-45 after neurological onset in 41/49 (84%) HSE patients, whereas only 21/63 (33%) of non-HSE patients and none of 18 healthy controls demonstrated measurable levels of sFas. Following the consecutive CSF sFas levels over the time and considering the clinical state of patients at admission, their neurological or lethal outcome at 12 months, and antiviral treatment, we observed that HSE patients with severe neurological sequels revealed an increase in changes of CSF sFas as compared to patients with mild or moderate neurological outcome (57.6+/-55.6 pg/ml, n=10 versus 26.3+/-97.5 pg/ml, n=14; P=0.008). Also HSE patients undergoing vidarabine treatment expressed significantly higher levels of changes of CSF sFas when compared to acyclovir-treated patients (63.7+/-52.8 pg/ml, n=9 versus 26.1+/-98.4 pg/ml, n=14; P=0.003). Interestingly, regardless of the clinical state at admission, and subsequent disease progression of the HSE patients, we could not observe any significant differences in the CSF sFas levels during the first 7 days of neurological symptoms. These observations underline the role of immunological response throughout the course of HSV infection in the brain and the role of the Fas/FasL pathway in particular in disease progression of HSE. The findings further enforce the need of expanding the knowledge of the pathogenesis of HSE to direct to more effective, in particular not only antiviral but also anti-apoptotic or anti-inflammatory treatment.
