Materials and methods for treating potentially chemoresistant tumors (e.g., using DNA-PKcs inhibitors and anti-B7-H1 antibodies) are provided herein.

A method of detecting triple negative breast cancer (TNBC) is provided. Overexpression of ICAM-1 is linked to an increased risk of TNBC. A composition of matter is also provided that binds an anti-ICAM-1 antibody to a nanoparticle. The composition may be used as an imaging agent and/or a therapeutic targeting agent. A therapeutically active molecule may be bound to the composition to provide targeted therapy.

The present disclosure relates to compounds that are useful as near-infrared fluorescence probes, wherein the compounds include i) a pteroyl ligand that binds to a target receptor protein, ii) a dye molecule, and iii) a linker molecule that comprises an amino acid or derivative thereof. The disclosure further describes methods and compositions for incorporating the compounds as used for the targeted imaging of tumors. Conjugation of the amino acid linking groups increase specificity and detection of the compound. Methods and compositions for use thereof in diagnostic imaging are contemplated.

The field of this invention relates to immunohistochemistry (IHC) and in situ hybridization (ISH) for the targeted detection and mapping of biomolecules (e.g., proteins and miRNAs) in tissues or cells for example, for research use and for clinical use such by pathologists (e.g., biomarker analyses of a resected tumor or tumor biopsy). In particular, the use of mass spectrometric imaging (MSI) as a mode to detect and map the biomolecules in tissues or cells for example. More specifically, the field of this invention relates to photocleavable mass-tag reagents which are attached to probes such as antibodies and nucleic acids and used to achieve multiplex immunohistochemistry and in situ hybridization, with MSI as the mode of detection/readout. Probe types other than antibodies and nucleic acids are also covered in the field of invention, including but not limited to carbohydrate-binding proteins (e.g., lectins), receptors and ligands. Finally, the field of the invention also encompasses multi-omic MSI procedures, where MSI of photocleavable mass-tag probes is combined with other modes of MSI, such as direct label-free MSI of endogenous biomolecules from the biospecimen (e.g., tissue), whereby said biomolecules can be intact or digested (e.g., chemically digested or by enzyme).

The present invention relates to the treatment of cancer, in particular breast cancer, particularly triple-negative breast cancer. More particularly, the invention concerns methods and means for cancer treatment involving a specific set of tumor antigens.

Disclosed is a method for detecting breast cancer biomarkers, which can be applied in cancer diagnosis and monitoring the effectiveness of cancer therapy. This fiber-optic biosensor-based approach employs advanced photonic techniques to identify specific biomarkers with high sensitivity and specificity. The technical result is achieved through a system including a fabricated and biologically functionalized fiber-optic biosensor, immersed in a controlled fluidic environment that mimics in situ conditions. The biosensor is integrated into a commercially available catheter, which is placed within a flow-through tube containing serum. The work focuses on enhancing biosensor performance under simulated blood-like conditions, including optimization of sensor positioning, packaging modifications, and assessment of specificity and sensitivity under varying pressure levels. The aim is to improve the efficiency, accuracy, and reliability of cancer biomarker detection, ultimately enabling earlier and more precise diagnosis for patient benefit.

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.

A method for predicting risk of recurrence of cancer in an individual with cancer, the method comprising a step of assaying a cancer sample from the individual for positive expression of at least two genes or proteins encoded by those genes selected from the group consisting of FOXM1, UHRF1, PTTG1, E2F1, MYBL2, HMGB2, ATAD2, E2F8, ZNF367 and TCF19, wherein positive expression of the at least two genes correlates with increased risk of recurrence of cancer compared with an individual who does not exhibit positive expression of the at least two genes or proteins encoded by those genes.

The invention relates to the detection of EGYR peptide in a biological sample as a measure of the presence and/or amount of LARP1 protein in the sample. Suitably, the invention relates to methods for quantitative measurement of LARP1 and LARP1-derived EGYR peptide by chromatography-tandem mass spectrometry. The invention also relates to peptide standards and their use in quantitative mass spectrometric analyses. The ability to detect the amount of LARP1 in a biological sample has application in detecting and monitoring cancer.

Provided herein are methods and systems of molecular profiling of diseases, such as cancer. In some embodiments, the molecular profiling can be used to identify treatments for a disease, such as treatments that were not initially identified as a treatment for the disease or not expected to be a treatment for a particular disease.
