We produced and identified the monoclonal antibodies against Brucella melitensis U‐lipoprotein OMP19 .A DNA fragment coding omp19 of Brucella melitensis was amplified by PCR ,and inserted into the vector of pET‐30a(+ ) ,the result‐ant recombinant plasmid ,which we designated as pET‐30a(+ )/omp19 .We then transformed the plasmid into BL21(DE3) competent cells for the expression of the OMP19 protein .After induction with different concentrations of IPTG ,the colleted cells were analyzed by SDS‐PAGE ,and then OMP19 monoclonal antibodies were prepared through hybridoma technology . These mAbs were tested to reactivity to rOMP19 and nature membrance proteins (NMP) of Brucella melitensis by Western blot and IEST .We successfully constructed an expression vector of pET 30a(+ )/omp19 .An IPTG‐induced expression of the OMP19 protein (19 kDa in molecular weight) was demonstrated by SDS‐PAGE .The fusion protein existed in the form of solu‐ble ,and the OMP19 protein of high purity could be obtained by Ni‐NTA .Western blot assay showed that the refolded protein could be recognized by the anti‐serum against Brucella melitensis .Twenty‐three mAbs to OMP19 was produced in which 91 .30% were IgG1 ,twenty‐two (95 .65% ) mAbs could recognize nature OMP19 protein ,and eighteen (78 .26% ) mAbs could recognize NMP ,four mAbs could react with Brucella melitensis .The protein maintained good immunogenicity and twenty‐three mAbs were obtained ,which we believe provides a good protein candidate for the immunological research .

As one of the hallmarks of cancer, metabolic reprogramming leads to cancer progression, and targeting glycolytic enzymes could be useful strategies for cancer therapy. By screening a small molecule library consisting of 1320 FDA-approved drugs, we found that penfluridol, an antipsychotic drug used to treat schizophrenia, could inhibit glycolysis and induce apoptosis in esophageal squamous cell carcinoma (ESCC). Gene profiling and Ingenuity Pathway Analysis suggested the important role of AMPK in action mechanism of penfluridol. By using drug affinity responsive target stability (DARTS) technology and proteomics, we identified phosphofructokinase, liver type (PFKL), a key enzyme in glycolysis, as a direct target of penfluridol. Penfluridol could not exhibit its anticancer property in PFKL-deficient cancer cells, illustrating that PFKL is essential for the bioactivity of penfluridol. High PFKL expression is correlated with advanced stages and poor survival of ESCC patients, and silencing of PFKL significantly suppressed tumor growth. Mechanistically, direct binding of penfluridol and PFKL inhibits glucose consumption, lactate and ATP production, leads to nuclear translocation of FOXO3a and subsequent transcriptional activation of BIM in an AMPK-dependent manner. Taken together, PFKL is a potential prognostic biomarker and therapeutic target in ESCC, and penfluridol may be a new therapeutic option for management of this lethal disease.
