The present invention is directed to a method of determining the likelihood of the presence of lung cancer in a subject. The method comprising determining the level of a biomarker selected from the group consisting of catalase (CAT), C-X-C motif chemokine receptor 4 (CXCR4), superoxide dismutase 3 (SOD3) and surfactant protein B (SFTPB) from a vesicle population isolated from a biological sample from said subject, wherein a change in the level of biomarker as compared to a reference indicates the likelihood of the presence of lung cancer in the subject.

The present invention discloses an application of a β3 adrenergic receptor (ADRB3) as a marker for detecting a plurality of diseases, and an application of anti-human ADRB3 monoclonal antibody in diagnosing a disease and preparing a drug for treating the disease. The present invention finds through research that the ADRB3 is a key receptor in nerve-endocrine-immunoregulatory network, and an ADRB3-mediated signaling pathway regulates proliferation and differentiation of neutrophils, lymphocytes and tumor cells. Under normal circumstances, the ADRB3 maintains the non-specific immunocompetence and specific immunocompetence of an organism, and eliminates pathogenic microorganisms and aged organism tissues to play a role in protecting the organism and anti-aging. Under pathological conditions, excessive activation of the signaling pathway will cause systemic chronic inflammation, and destroy immune homeostasis. Therefore, the ADRB3 can be used as a diagnostic marker and a therapeutic target for a plurality of diseases. Anti-human ADRB3 antibody can specifically bond with the ADRB3, regulate the activity of the ADRB3, has the functions of resisting cancer, inflammation, poisoning, shock, allergy, viral infection, autoimmune disease, disease caused by regenerative dysfunction, autoimmune disease, cachexia, cardiovascular and cerebrovascular disease, neurodegenerative disease and aging, regulating autophagy, treating aging disease, etc., and has important medical value and research and application prospects.

Methods of treating cancer with a combination of a WEE1 inhibitor and a DNA-damaging agent in patients having SLFN11-deficient cancer cells are disclosed herein.

The disclosure provides methods for measuring M-proteins in a biological sample obtained from a subject, comprising applying purified immunoglobulins to a liquid chromatography (LC) mass spectrometry (MS). In some aspects, the immunoglobulins are purified using an immunocapture (IC). In certain aspects, the subject has a plasma cell disorder, e.g., multiple myeloma.

The present disclosure provides biomarkers useful as companion diagnostics for detecting glycocalyx-based disease that is amenable to treatment using compounds designed for improving the condition of the glycocalyx and/or reducing inflammation and/or oxidative damage, as well as related compositions, kits, and methods.

The present invention discloses that cancer cells secrete succinate into extracellular milieu, which increases macrophage migration and mediates TAM polarization. Furthermore, succinate induces cancer cell EMT, enhances cancer cell migration, and promotes cancer metastasis in murine models. It is indicated in the present invention that serum succinate concentration is elevated in patients with lung cancer when compared to healthy subjects. It implies that during cancer development and progression, cancer cells release a large quantity of succinate into the circulation. As shown in the present invention, serum succinate has a high discriminatory power, it represents a new class of circulating oncometabolite with potential value for predicting NSCLC. Furthermore, as elevation of succinate level in LLC tumor model is accompanied by increased TAMs in the subcutaneous tumors and enhanced cancer metastasis, serum succinate may be a useful therapeutic biomarker for NSCLC treatment. The present invention also provides an anti-succinate antibody that can serve as a cancer therapeutic agent.
