In one aspect, a method for screening an individual for head and neck cancer, which comprising: acquiring a saliva sample from the individual, analyzing the saliva sample to detect one or more of HPVs and at least one of a phenotypic biomarker, a regulatory biomarker, a microbiome-derived biomarker, and a metabolomic biomarker dysregulated due to HPV infection, wherein detection of both of the HPV and at least one of said biomarkers indicates the individual is at risk of head and neck cancer.

An assay measuring protease mediated degradation of type IV collagen and its biomarker potential for identifying cancer patients with a T-cell permissive tumor microenvironment is described.

A pro-moiety and a composition comprising a pro-moiety for use in a therapeutically or diagnostically effective amount in a method for detecting and/or treating prostate cancer in a subject is disclosed. The pro-moiety comprises a first peptide, and a second peptide that is linked to the first peptide, wherein the peptide comprises a sequence that is configured near a first terminus for conjugating to a drug to form a prodrug that is rapidly and/or highly selectively cleaved by prostate-specific antigen (PSA), and configured at a second terminus to bind with high selectivity to the active site of PSA, and the second peptide comprises a sequence having a negative charge to slow uptake of the prodrug by cells, and wherein the second peptide is cleaved from the first peptide upon proteolysis by PSA to produce a conjugate of the first peptide and the drug that is suitable for uptake by target cells.

This disclosure describes the characteristics of the energetic cancer stem cell (e-CSC) phenotype. This distinct sub-population of cancer stem cells (CSCs) has a unique energetic profile compared to bulk CSCs, being more glycolitic, having higher mitochondrial mass and elevated oxidative metabolism. e-CSCs also show an increased capacity to undergo cell cycle progression, enhanced anchorage-independent growth, and ALDH-positivity. The e-CSC phenotype presents new targets for cancer therapeutics, and in particular the anti-oxidant response, mitochondrial energy production, and mitochondrial biogenesis of e-CSCs makes them highly susceptible to mitochondrial inhibitors that target e-CSC anti-oxidant response, mitochondrial energy production, and mitochondrial biogenesis. Gene products for e-CSCs are disclosed, as well as classes of mitochondrial inhibiting therapeutic agents. Also disclosed are methods for identifying and separating e-CSCs front bulk cell populations.

An antigen and antibodies prepared based on peptidylarginine deiminase (PADI4) serving as a tumor marker, and application thereof are disclosed. The antigen has an amino acid sequence shown as SEQ ID NO. 1. Specific antibodies prepared by using the antigen are also disclosed. The protein PADI4 monoclonal antibodies include a protein PADI4 monoclonal antibody coated onto an ELISA plate and a biotin-labeled protein PADI4 monoclonal antibody. A kit prepared by using the antibodies of the present disclosure can effectively and stably determine a protein PADI4 level of a human serum, and has a broad spectrum, detectability, and high test repeatability.

Described herein are detecting methods for conformational disease, aging and proteinopathies, by measuring the presence of b-isox-precipitates and the levels of b-isox-captured proteins in biofluids of healthy individuals and patients. Research identified additional biomarkers, which made it possible to detect, diagnose or treat, a human disease in a human subject by, with or without adding an isoxazole to an obtained biofluid sample, detecting the biomarker. Use of b-iso and/or biomarkers for diagnosing the disease are made possible.

The present invention is directed to anti-PVRIG antibodies and stable liquid pharmaceutical formulations thereof. The present invention is directed to monotherapy and combination treatments with anti-PVRIG antibodies and anti-PD-1 antibodies, in particular nivolumab, using stable liquid pharmaceutical formulations thereof. The present invention also provides biomarkers for use in determining populations for treatment with anti-PVRIG antibodies and such biomarkers include, for example PVRIG and/or PVRL2 expression.

Disclosed is a method for diagnosing a patient's breast cancer (BC) health state, or change in BC health state, or for diagnosing risk of BC or the presence of BC in a patient, comprising detecting, in a plasma sample from said patient, one or more biomarker values that corresponds to thrombospondin-1 (THBS1) or a THBS1-containing complex structure by performing a capillary electrophoresis under non-reducing conditions, and assigning the patient as having or not having BC, or having or not having a change in BC health state, or having or not having a risk of BC based on said biomarker values.

The invention relates to methods for separating circulating cell free nucleosomes comprising linker DNA from a biological fluid sample, in particular nucleosomes of disease origin. Such methods allow for improved analysis of genetic and epigenetic markers associated with nucleosomes of disease origin.

The invention relates to methods and uses of cell free histone H3 isoforms H3.1, H13.2, H3t and/or H3.3 (or cell free nucleosomes containing said isoforms) of determining the origin of a cell free histone or cell free nucleosome in a body fluid sample as originating from a dividing or non-dividing cell.
