Abstract
BACKGROUND Metastatic colorectal cancer (mCRC) patients tend to have modest benefits from molecularly driven therapeutics. Patient-derived tumor organoids (PDTOs) represent an unmatched model to elucidate tumor resistance to therapy, due to their high capacity to resemble tumor characteristics. MATERIALS AND METHODS We used viable tumor tissue from two cohorts of patients with mCRC, naïve or refractory to treatment, respectively, for generating PDTOs. The derived models were subjected to a 6-day drug screening assay (DSA) with a comprehensive pipeline of chemotherapy and targeted drugs against almost all the actionable mCRC molecular drivers. For the second cohort DSA data were matched with those from PDTO genotyping. RESULTS A total of 40 PDTOs included in the two cohorts were derived from mCRC primary tumors or metastases. The first cohort included 31 PDTOs derived from patients treated in front line. For this cohort, DSA results were matched with patient responses. Moreover, RAS/BRAF mutational status was matched with DSA cetuximab response. Ten out of 12 (83.3%) RAS wild-type PDTOs responded to cetuximab, while all the mutant PDTOs, 8 out of 8 (100%), were resistant. For the second cohort (chemorefractory patients), we used part of tumor tissue for genotyping. Four out of nine DSA/genotyping data resulted applicable in the clinic. Two RAS-mutant mCRC patients have been treated with FOLFOX-bevacizumab and mitomycin-capecitabine in third line, respectively, based on DSA results, obtaining disease control. One patient was treated with nivolumab-second mitochondrial-derived activator of caspases mimetic (phase I trial) due to high tumor mutational burden at genotyping, experiencing stable disease. In one case, the presence of BRCA2 mutation correlated with DSA sensitivity to olaparib; however, the patient could not receive the therapy. CONCLUSIONS Using CRC as a model, we have designed and validated a clinically applicable methodology to potentially inform clinical decisions with functional data. Undoubtedly, further larger analyses are needed to improve methodology success rates and propose suitable treatment strategies for mCRC patients.

Abstract
In order to detect putative markers of prolactin-secreting pituitary tumours, adult rats were subjected to long-term oestrogenization with oestradiol benzoate (OE2) on a monthly basis. At 6 months, anterior pituitaries were dissected and incubated either as tissue fragments or as dispersed cells with a [35S]methionine mix for labelling. Proteins released into the incubation medium and from tissue extracts were further analysed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis and fluorography. Oestrogen induced the appearance in the incubation medium of a protein (OE2 band) with an M(r) of 38,000 under reducing conditions, and high specific activity. Surprisingly, such a protein was not detected in tissue extracts. The OE2 band was detectable by 7 days after the first dose of oestrogen, and remained throughout 1 year of treatment. The tumour cell line GH3 showed a similar OE2 band which was further enhanced by oestrogens. The protein was observed similarly in both female and male pituitary donors, either intact or gonadectomized, and also in rats of different strains, suggesting that its appearance was independent of the strain of rat and gonadal status. Furthermore, the OE2 band was specific for pituitary cells and not produced by other oestrogenized tissues. No alteration in the rate of generation or the electrophoretic pattern of the OE2 band was observed when pituitary cells from oestrogenized rats were metabolically labelled while being incubated with tunicamycin. Furthermore, a system for glycan detection, adsorption to Concanavalin A or incubation with endoglycosidase F also failed to show a clear amount of glycosylation of the oestrogen-induced protein. Both immunoprecipitation experiments and time-limited proteolysis with V8 protease ruled out the possibility that the OE2 band could be structurally related to either GH or prolactin. In conclusion, oestrogens induce the generation of a new monocatenary protein with an apparent M(r) of 38,000, which has at least one intramolecular disulphide loop and is not glycosylated. The OE2 band was detected only in incubation medium and never in tissue extracts.
