Abstract 4281: Oncostatin M renders epithelial cell adhesion molecule-positive liver cancer stem cells sensitive to 5-fluorouracil by inducing hepatocytic differentiation
Recent evidence suggests that a certain type of () is hierarchically organized by a subset of cells with stem cell features (stem cells; ). Although normal stem cells and are considered to share similar self-renewal programs， it remains unclear whether differentiation programs are also maintained in and effectively used for eradication. In this study， we investigated the effect of oncostatin M ()， an -related cytokine known to induce the differentiation of hepatoblasts into hepatocytes， on liver . receptor expression was detected in the majority of epithelial molecule-positive (EpCAM(+)) with stem/progenitor cell features. treatment resulted in the induction of hepatocytic differentiation of EpCAM(+) cells by inducing signal transducer and activator of 3 activation， as determined by a decrease in stemness-related gene expression， a decrease in EpCAM， alpha-fetoprotein and protein expressions， and an increase in albumin protein expression. -treated EpCAM(+) cells showed enhanced with expansion of the EpCAM-negative non-population. Noticeably， combination of treatment with the chemotherapeutic agent (5-FU)， which eradicates EpCAM-negative non-， dramatically increased the number of apoptotic cells in vitro and suppressed in vivo compared with either saline control， ， or 5-FU treatment alone. Taken together， our data suggest that could be effectively used for the differentiation and active of dormant EpCAM(+) liver ， and the combination of and conventional chemotherapy with 5-FU efficiently eliminates by targeting both and non-.

Human aquaporin 4281-300 is the immunodominant linear determinant in the context of HLA-DRB1*03:01: relevance for diagnosing and monitoring patients with neuromyelitis optica.
Abstract OBJECTIVE To identify linear determinants of human aquaporin 4 (hAQP4) in the context of HLA-DRB1*03：01. DESIGN In this controlled study with humanized experimental animals， HLA-DRB1*03：01 transgenic mice were immunized with whole-protein hAQP4 emulsified in complete Freund adjuvant. To test T-cell responses， lymph node cells and splenocytes were cultured in vitro with synthetic peptides 20 amino acids long that overlap by 10 amino acids across the entirety of hAQP4. The frequency of interferon γ， interleukin (IL) 17， granulocyte-macrophage colony-stimulating factor， and IL-5-secreting CD4+ T cells was determined by the enzyme-linked immunosorbent sport assay. Quantitative immunofluorescence microscopy was performed to determine whether hAQP4281-300 inhibits the binding of anti-hAQP4 recombinant antibody to surface full-length hAQP4. SETTING Academic neuroimmunology laboratories. SUBJECTS Humanized HLA-DRB1*03：01+/+ H-2b-/- transgenic mice on a B10 background. RESULTS Peptide hAQP4281-300 generated a significantly (P <.01) greater TH1 and TH17 immune response than any of the other linear peptides screened. This 20mer peptide contains 2 dominant immunogenic 15mer peptides. hAQP4284-298 induced predominantly an IL-17 and granulocyte-macrophage colony-stimulating factor TH cell phenotype， whereas hAQP4285-299 resulted in a higher frequency of TH1 cells. hAQP4281-300 did not interfere with recombinant AQP4 autoantibody binding. CONCLUSIONS hAQP4281-330 is the dominant linear immunogenic determinant of hAQP4 in the context of HLA-DRB1*03：01. Within hAQP4281-330 are 2 dominant immunogenic determinants that induce differential TH phenotypes. hAQP4 determinants identified in this study can serve as diagnostic biomarkers in patients with neuromyelitis optica and may facilitate the monitoring of treatment responses to pharmacotherapies.

Abstract 4281: Determination of the Relative Potency of a Selective Agonist of the Intermediate-Affinity IL-2 Receptor on Lymphocytes from Human, Cynomolgus Monkey and Mouse
RDB 1450 is an engineered fusion protein designed to selectively activate the intermediate-affinity IL-2 receptor versus the high-affinity IL-2 receptor. The potencies of RDB 1450 and IL-2 for activation of distinct subsets of effector and regulatory lymphocytes from murine， non-human primate and human donors were determined. Splenocytes isolated from mice or leukocytes isolated from human or cyno blood were stimulated with either RDB 1450 or IL-2. Multicolor flow cytometry was used to identify distinct subpopulations and the extent of phosphorylation of STAT5 was measured. Whereas IL-2 is 2-3 orders of magnitude more potent on immunosuppressive T regs relative to NK cells and memory CD8 T cells， RDB 1450 induces activation of NK cells， memory CD8 T cells and T regs at comparable concentrations within each species. The non-differentiated potency of RDB 1450 on the lymphocyte subpopulations examined suggests that its effects are mediated through the intermediate affinity receptors even on CD25-expressing T regs . The preferential activation of T regs by IL-2 may lead to immunosuppression and limit its antitumor efficacy. In contrast， RDB 1450 does not exhibit the same preference for T reg activation and is expected to be more effective in driving antitumor immune responses. These results highlight the differentiated immunological profile of RDB 1450 and support its potential as a novel human immunotherapy.Citation Format： Emily E. Rosentrater， Heather Flick， Jared E.

Background： To provide a systematic analysis of formalin fixation artifacts on Illumina sequencing libraries and results， we generated two complementary sequencing libraries (target enrichment sequencing and whole exome sequencing) from 11 pairs of matched formalin-fixed paraffin-embedded (FFPE) and fresh-frozen (FF) tumor samples and two pairs of matched FFPE and FF germline samples. We also generated whole genome sequencing data from a single pair of FF/FFPE tumor samples. Results： The results indicate minimal variations in library fragment size， coverage， and PCR duplicates within FF/FFPE paired samples that are less than 1 year old; whereas， a large variation in these parameters were observed in FF/FFPE pairs in samples that are approximately 2 years old. No significant increase in global mismatch rates and C•G>T•A substitutions were observed in FFPE samples from the former group; whereas， a discernible increase in mismatch rates and C•G>T•A substitutions were observed in FFPE samples from the latter group. However， over 99.7% and 99.5% of concordant calls were observed between matched FF and FFPE pairs at reference and non-reference positions within the targeted regions， respectively. Although an increased rate of global mismatches and C•G>T•A substitutions were observed in some FFPE samples， discordant rates were low (T•A substitutions are comparable in non-reference positions in paired FF and FFPE samples. Conclusions： We developed upfront quality assessment and library preparation method that use low input DNA from FFPE samples to perform next-generation sequencing. The results from our studies indicate the suitability of FFPE samples in sequencing studies.
