Time-staggered inhibition of EGFR, in combination with DNA damaging agents, is a useful therapeutic strategy for treating cancers, particularly drug resistant cancers such as a subset of triple-negative tumors, particularly those with high basal levels of phosphorylated EGFR. The staggered therapy was also demonstrated to be applicable to other types of tumors, especially lung cancers, which contain either high levels of phosphorylated wild-type EGFR or mutations within EGFR itself. EGFR inhibition dramatically sensitizes cancer cells to DNA damage if the drugs are given sequentially, but not simultaneously. The first drug must be administered in a dosage and for a period of time sufficient for the dynamic network rewiring of an oncogenic signature maintained by active EGFR signaling to unmask an apoptotic process that involves activation of caspase-8.

A method for the diagnosis of breast cancer using an anti-LAT1 monoclonal antibody. Among intraductal breast neoplastic lesions, duct carcinoma in situ, which is malignant, expresses LAT1 at a significantly high level, as compared to intraductal breast papilloma, which is benign. An anti-LAT1 monoclonal antibody is useful for the discrimination between these two lesions. Further, LAT1 is expressed at a high level in most of triple negative infiltrating carcinomas, which are negative for all of ER, PgR, and HER2 that are conventional molecular targeting markers for breast cancer. Therefore, LAT1 can be used as a novel molecular targeting marker for the triple negative breast cancer.

In one aspect, the present disclosure provides a method of predicting disease progression comprising: (a) obtaining a sample of breast tissue that is estrogen receptor negative, progesterone receptor negative and does not over-express human epidermal growth factor 2 receptor protein; and (b) determining the expression of glia maturation factor beta, wherein expression of glia maturation factor beta is indicative of lymph node metastatis. In another aspect, the present disclosure provides a method of predicting disease progression comprising: (a) obtaining a sample of breast tissue that is estrogen receptor negative, progesterone receptor negative and does not over-express human epidermal growth factor 2 receptor protein; and (b) determining the expression of glia maturation factor beta, wherein expression of glia maturation factor beta is indicative of an untreated or treated prognosis that is reduced compared to an absence of the expression.

The invention provides application of protein DEPDC1 (Dishevelled and EGL-10, Pleckstrin Domain-Containing protein 1) as a marker for diagnosing the triple negative breast cancer, and also provides application of miR-26b for preparing a medicine for treating the triple negative breast cancer. The invention also provides application of miR-26b for preparing a medicine for inhibiting DEPDC1 mRNA (Ribonucleic Acid) expression. The invention finds that DEPDC1 expression is obviously higher than a paired para-carcinoma tissue in a triple negative breast cancer tissue. In the triple negative breastcancer cell, overexpression DEPDC1 can accelerate cell growth and tumor formation through FOXM1 (Forkhead box protein M1) expression up-regulation. On the contrary, after the DEPDC1 is knocked down,an inverse function is displayed. In addition, in the triple negative breast cancer, miR-26b serves as a tumor inhibiting factor to directly inhibit DEPDC1 expression and weaken the acceleration function of the DEPDC1 for cell growth and clone formation. The invention points out a new important mechanism for the occurrence, the development, the regulation and the control of the triple negative breast cancer.

Described herein is a previously unknown function of XBP1 in triple-negative breast cancer (TNBC). It is shown that XBP1 is preferentially spliced and activated in TNBC, and that deletion of XBP1 significantly blocks triple negative breast tumor growth. Strikingly, XBP1 is required for the self-renewal of breast tumor initiating cells (TICs). Genome-wide mapping of the XBP1 transcriptional regulatory network identified a fundamental role for XBP1 in regulating the response to hypoxia via the transcription factor hypoxia-inducible factor 1α (HIF1α). Importantly, activation of this pathway appears to carry prognostic implications, as expression of the XBP1-dependent signature is associated with shorter survival times in human TNBC.

The invention relates to CD146 and antibody diagnosis thereof, and an application thereof in treating triple negative breast cancers. For a first time, the invention provides that CD146 is a novel target of triple negative breast cancer, and an anti-CD146 antibody might become a novel targeting medicine for treating the disease. Therefore, the invention provides an application of CD146 or anti-CD146 antibody or a functional form of the antibody in preparing medicines used for diagnosing and / or treating triple negative breast cancers. CD146 molecules are subjected to specific high expression in triple negative breast cancer tissues, and induce the occurrences of transformation of epithelial cell to mesenchymal cell in tumor cells. Therefore, tumor invasion migration is promoted. Therefore, the mechanism for CD146 antibody to treat triple negative breast cancer is mainly that the CD146 antibody inhibits the mesenchymal cell characteristics of triple negative breast cancer, and reduces the metastasis invasion capacity thereof. Compared with common chemotherapy medicines, the anti-CD146 antibody has the advantages of low side effects and clear target. The anti-CD146 antibody does not cause whole-body side effect.

The present invention is based on our work with E-cadherin, including soluble portions of this integral membrane glycoprotein. The compositions of the present invention include therapeutically effective amounts of a first agent that targets epitopes within one or more of the EC2-EC5 subdomains of the ectodomain of E-cadherin (induing these domains in the shed sEcad fragment) and a second agent that inhibits one or more of: endothelial tube formation; angiogenesis; the human epidermal growth factor receptor family (i.e. HER1-4); an insulin-like growth factor 1 receptor (IGF-1R); any other receptor tyrosine kinase receptor family member; the P13K-MAPK pathway; and the P13K / Akt / mTOR pathway. The compositions can be used in the treatment of epithelial cancers, and may effectively inhibit cellular proliferation, migration, and / or invasiveness. Thus, the present compositions can be used to inhibit tumor growth and metastasis. The present compositions can be used in the treatment of "triple negative" breast cancer patients (in whom breast cancer cells test negative for estrogen receptors, progesterone receptors, and HER2), as well as HER2 -positive and other HER2 -negative tumors. In addition to therapeutic and prophylactic treatment methods, the invention features methods in which cancer is staged depending on the relative amounts of full-length (FL) E-cadherin and soluble E-cadherin (sEcad) and / or with another predictive biomarker for cancer. The greater the amount of sEcad relative to the amount of FL E-cadherin, the more advanced the cancer.
