[0227]
[0228] RMA-S lymphoma cells at limiting number (4×10.sup.5) were injected s.c in the flank of female C57BL/6 mice at D0. Mice were randomized in three groups to receive PBS, rmCHI3L1 (0.5 ug/mouse i.p every other day starting D0), or anti-NK1.1 antibody for NK cell depletion (150 ug/mouse i.p on D0, D2, D4). Tumor take and tumor growth were scored every two days. After sacrifice, tumors were weighted and imaged.

[0230] 3×10.sup.6 JIMT-1 cells overexpressing CHI3L1 (JIMT-1CHI311) or 4×10.sup.6 cells transfected with empty plasmid (JIMT-1 Mock) were injected subcutaneously in the flank of BALB/c Nude mice. The injection of a higher number of JIMT-1 Mock cells was done to compensate for the faster tumor growth of CHI3L1 overexpressing ones. I.p Treatment with 10 mg/kg Trastuzumab or hIgG isotype control was started when tumors reached 50 mm.sup.3 and was given once every week. Tumor take and tumor growth were scored every two days. After sacrifice, tumors were weighted and imaged.

Anti-CHI3L1 treatment was started on D-1 (200 ug/mouse every two days) and Trastuzumab treatment was started on D1 (200 ug/mouse once a week) of NK cell transfer. Experiment was stopped when Isotype control treated mice developed necrotic tumors at which time the Trastuzumab+NK cell+anti-CHI3L1 mice had two tiny Tumors remaining. Mice were then sacrificed and tumors were imaged.

Materials and Methods
Patients
[0233] Women with histological diagnosis of locally advanced invasive or metastatic BC were considered eligible for the study if classified as HER-2 positive, i.e. score 3+ (by immuno-histochemical analysis: IHC) or IHC score 2+ and FISH (fluorescence in situ hybridization) amplified. Thirty BC patients were enrolled in the study that underwent a first line chemotherapy in combination with trastuzumab. Response to trastuzumab was evaluated on the basis of clinical, pathological and radiologic examination of the tumor before and after treatment. The revised RECIST criteria (version 1.1) were used to evaluate the treatment response which was classified as complete response (CR) and disease progression (PD). Blood samples were collected at basal (before Trastuzumab therapy) and subsequently until patients reached PD or RC state (12 months).
[0234] This study was approved by the Ethics Committee of the European institute of oncology hospital, Milan, Italy and written informed consent was obtained from each patient.
Cytotoxicity Assay
[0235] NK cell and CD8 T cell-mediated cytotoxicity was determined using the DELFIA® EuTDA Cytotoxicity Reagents (PerkinElmer Life Sciences, Waltham, Mass., USA), according to manufacturer's instructions. Briefly, target cells (1×10.sup.6 cells/ml) were incubated with freshly prepared 10 μM BATDA (a fluorescence enhancing ligand) in 2 ml of culture medium for 30 min at 37° C., and washed. Next, 100 μl of BATDA-labeled target cells (5,000 cells) were transferred into a V-bottom sterile plate. In ADCC assays SKBR3 cells (commercial from ATCC, HTB30) were treated with 10 ug/ml Trastuzumab (Roche) for 20 min at 37° C. and in primary CD8 T cells [from healthy donors, after informed consent] cytotoxicity MEC1 targets (IEO cell line bank) were loaded with 2 ug/ml SEB sAg (SIGMA) for 30 min at 37° C. Effector cells were treated as described in each experiment and then co-cultured wit target cells for 1 h 30 min in case of ADCC and 2 hours in case of natural NK cytotoxicity or CD8 T cells cytotoxicity at effector/target ratio of 10:1. After incubation, 20 μl of supernatant from each well was transferred to the wells of flat-bottom 96 well plates. 180 μl of europium (Eu) solution was then added to form highly fluorescent and stable chelates (EuTDA), and the fluorescences of these chelates were measured by time-resolved fluorometry (Victor3, PerkinElmer). The percent of specific release was calculated using (experimental release−spontaneous release)/(maximum release−spontaneous release)×100(%). In blocking experiments, anti-CHI3L1 (clone MaY, MABC196, Sigma-Aldrich) or mIgG1 isotype (EMD millipore) or rhsILl3ra2 (abcam) was pre-incubated with the treatment agent (patient Serum or rhCHI3L1) for 1 h before adding the mixture to suspensions of NK cells and incubating for 1 h prior to co-cultured with target cells. All experiments were performed in triplicate.
Flow Cytometry
[0236] Single-cell suspensions, of blood or from cell culture, were obtained and incubated with Fc receptor-blocking antibody before being stained on ice. Dead cells were excluded by live/dead staining using fixable live/dead stain dyes (Thermofisher scientific). Primary NK cells [from healthy donors, after informed consent] were gated as singlets, CD14neg, FSC−. SSC appropriate for lymphocytes, CD3neg, CD16/CD56 poscells. Intracellular staining was performed using a fixation and permeabilization buffer (BD Bioscience). For phosphoflow experiments NK cells were fixed with 4% PFA for 12 min at 37° C. immediately after treatment time and permeabilized with Ice cold PermIII buffer (BDbioscience) for 30 min on ice. Stained cells were analyzed on FACSCanto II cytometer (BD Biosciences). Cell doublets were excluded by comparison of side-scatter width to forward-scatter area. Flow cytometry data were analyzed with FlowJo v10 software (Tree Star).
Results
[0237] To investigate the involvement of NK cell mediated ADCC in trastuzumab resistance, inventors collected sera from metastatic breast cancer patients treated with trastuzumab in adjuvant therapy. NK cells isolated from healthy donors were incubated with the patients' sera and tested for cytotoxic activity. Inventors found that response to trastuzumab can be predicted based on the capacity of serum from treated patients to influence the activity of healthy NK cells where sera from non-responders (N=8) reduced NK cell activity, while sera from responders had no effect on NK cell activity (N=11) (
[0238] To identify the molecules involved in the observed phenomenon, inventors carried out a comparative proteomic analysis of the sera of responder versus non-responder patients and identified some molecular candidates that may explain both innate and acquired resistance to trastuzumab. Among these, Chitinase 3-like 1 protein (CHI3L1) was found high at baseline in sera of non-responders or increased during therapy in the sera of patients with acquired resistance (
[0239] To test if CHI3L1 is directly responsible for the decreased cytotoxic activity, we pretreated NK cells with rhCHI3L1 before incubating them with target cells. Inventors found that addition of CHI3L1 impairs both antibody-dependent and natural cytotoxicity of human and murine NK cells in a dose dependent manner (
[0240] To test the possibility of restoring trastuzumab dependent cytotoxicity of NK cells, inventors co-incubated with a CHI3L1 neutralizing antibody (mAY) or soluble rhIL13ra2. Both methods abrogated the inhibitory effect of CHI3L1 (
[0241] To elucidate the molecular mechanism by which CHI3L1 is acting on NK cells. Inventors first analyzed the expression of receptor of advanced glycation end products (RAGE). Consistent with a previously described activator function of RAGE in murine NK cells inventors found this receptor to be expressed at high levels on CD56+ NK cells. Further, the expression of RAGE was downmodulated after incubation with CHI3L1 suggesting the internalization of RAGE upon CHI3L1 binding (
[0242] Inventors next tried to validate the role of RAGE in NK cell cytotoxicity. RAGE blocking antibody, similarly to CHI3L1, inhibited NK cell ADCC and induced a decrease of lytic granules (

Materials and Methods
Tumor Models
[0243] Mice were purchased from Charles River Laboratories and were cared for and used under specific pathogen-free conditions according to the guidelines established in the Principles of Laboratory Animal Care (directive 86/609/EEC). RMA-S cells were a kind gift from Dr. Sebastian Kobold (LMU, Munich). JIMT-1 and HCC1569 cell lines were purchased from ATCC. Tumor cells at 70% confluence were washed twice and resuspended in cold PBS and kept on ice during the injection procedure. Tumor measurements and endpoints were registered by an observer blinded to the treatment groups.
Results
[0244] RMA-S tumors are vulnerable to NK cell lysis. Injecting mice with CHI3L1 leads to a drastic increase in tumor establishment and tumor growth similar to that of mice where NK cells have been depleted (anti-NK1.1) (
[0245] JIMT-1 tumors are resistant to Trastuzumab in vitro. However, a partial tumor control can be achieved in vivo thanks to NK cell ADCC. Therefore, a dysfunction of NK cell ADCC in this model will directly reflect negatively on the ability of Trastuzumab to control tumor growth. Indeed, JIMT-1 tumors that do not express CHI3L1 (Mock) were controlled by Trastuzumab injections. On the other hand, CHI3L1 overexpression abrogated tumor control where tumors were rendered completely insensitive to Trastuzumab Injections (
