Clinical gene signature-based human cell culture model and uses thereof

A screening method for identifying an agent for the treatment or prevention of a non-hepatic cancer, said method comprising steps of:

• (1) generating a cellular model using a method comprising steps of:
• (a) providing non-hepatic cancer cells;
• (b) submitting said non-hepatic cancer cells to 20 mM to 60 mM of ethanol to obtain non-hepatic cancer cells exhibiting a Prognostic Liver Signature (PLS) high-risk gene signature,
• wherein said non-hepatic cancer cells exhibiting the PLS high-risk gene signature and obtained in step (b) exhibit:
• i. an increase in overall expression of a set of 73 high-risk genes, or a subset thereof, compared to the overall expression of said set of 73 high-risk genes, or subset thereof, in non-hepatic cancer cells cultured in the absence of ethanol, all other things being equal,
• wherein the 73 high-risk genes are FSHB, SH3GL2, RBM34, NCAPH, EGF, TRIO, COL6A3, ABLIM1, ITGA9, NTS, SERPINB2, MMP7, PRKG2, EDG4, NOS2A, EPHA4, SP100, FMO1, GPX2, ATP4B, IER3, WIPF1, IGFBP6, CTNND2, FBN1, GBA, ICK, CHERP, HDAC9, NOL7, IQGAP1, ADD3, ANXA3, HMG20B, SLC12A2, COL4A1, CPA3, KRT7, SERPINB8, NFKB2, AEBP1, TGFB1I1, EMP2, BCL2, PSMB9, ACTR2, DDR1, SLC7A1, PODXL, COL16A1, IF130, EPM2AIP1, ANXA1, CCL21, CHSY1, AP11B1, TEAD4, ELOVL2, TCF4, TSC22D2, DUSP5, CCDC6, CD48, TNK2, DAB2, LOXL2, RNASE1, LPP, CXCR4, SLIT3, FILIP1L, CCL19, and AKAP13,
• and wherein the subset of said 73 high-risk genes consists of the 19 high-risk genes:
• FSHB, SH3GL2, RBM34, NCAPH, EGF, TRIO, COL6A3, ABLIM1, ITGA9, NTS, SERPINB2, MMP7, PRKG2, EDG4, NOS2A, EPHA4, SP100, FMO1, and GPX2;
• and
• ii. a decrease in overall expression of a set of 113 low-risk genes, or a subset thereof, compared to the overall expression of said set of 113 low-risk genes, or a subset thereof, in non-hepatic cancer cells cultured in the absence of ethanol, all other things being equal,
• wherein the 113 low-risk genes are ALDH9A1, TTR, RLF, IMPA1, PFKFB1, ACSM3, ADRA2B, PTPN2, PSMB3, PPP1R1A, TMEM97, PKLR, RPS6KA5, CYB5A, SCG5, TXN2, PLG, SC5DL, AR, IGF1, SUCLG1, HAAO, C9, TAF1C, CPOX, XPA, HABP2, GHR, PCK1, AKR1D1, ADH5, AARS, C8B, MGC29506, ATP6AP2, DOCK4, PROS1, ZBTB17, DAD1, TIMM8A, HMGCL, C4BPB, TRAF6, EIF2B1, LIPC, PIGK, WDR23, RFC2, GRM5, SDHC, ERCC5, F9, ANKRD46, ART1, CTBS, SLC37A4, ALAS1, VPS41, GCGR, CCT8, BRP44, GRK4, HSPE1, NARS2, DST, ATP2C1, AKR1A1, EMD, CALCR, DLGAP4, RRM1, NENF, SNX10, PMM1, TDO2, GSTM1, SREBF2, PTPN18, ASAHL, PLCG2, KCNJ3, PCYT2, GJB1, TM7SF2, SELENBP1, AOX1, ZER1, ADH6, MSH6, SLC4A4, USP14, C5, RAD52, FAM129A, BAIAP2, SSFA2, PON3, GCKR, CREB1, CUTL2, SFRS2, HMGCR, GGCX, CYP2B6, ZNF185, ARF4, ACOT2, ATP5D, CPN1, PLCB3, INSM1, POLRMT, and HRASLS3,
• and wherein the subset of said 113 low-risk genes consists of the 13 low-risk genes:
• ALDH9A1, TTR, RLF, IMPA1, PFKFB1, ACSM3, ADRA2B, PTPN2, PSMB3, PPP1R1A, TMEM97, PKLR, and RPS6KA5;
• (2) contacting cells of the cellular model with a candidate compound;
• (3) determining the effect of the candidate compound on the PLS high-risk gene signature;
• (4) identifying the candidate compound as an agent useful for the treatment or prevention of a non-hepatic cancer if the candidate compound suppresses the overall expression of the set of 73 high-risk genes, or the subset thereof, and/or induces the overall expression of the set of 113 low-risk genes, or the subset thereof.
