Anti-mitochondrial inhibitors for oncogenic Ras and Myc

The present disclosure relates to a Proteomics-to-Genomics approach allows for in silico validation of biomarkers and drug targets. Biomarkers having high prognostic value in predicting cancer patient populations that may benefit from mitochondrial biogenesis inhibitor therapy may be identified under the present approach. Also disclosed are methods for identifying candidates for anti-mitochondrial therapy, and in particular mitochondrial biogenesis inhibitor therapy. Diagnostic kits including reagents for determining transcripts or probes of high prognostic value are also disclosed. Additionally, mitochondrial biogenesis inhibitors may be used as anti-cancer agents for diverse oncogenic stimuli, including for example, c-MYC and H-Ras oncogenes, as well as environmental stimuli such as, for example rotenone.

METHODS OF DETECTING CANCER
20230228753 · 2023-07-20 ·

Method and kits for detecting cancer, and in particular breast cancer, in a subject by measuring the levels of at least one of a series of biomarkers, as compared to a control sample lacking cancer. The expression of the biomarker either increases or decreases in samples from subjects with cancer, as compared to the expression level in subjects without cancer. The sample is optimally an ocular sample, such as an isolated tear sample or ocular wash, but can also be from saliva, or other bodily fluid. Kits can include a collection tube and protease inhibitors or protein stabilizers.

Cancer test device, cancer test method, and staining agent for use in cancer test

A cancer test device (1) is provided with: an application unit (40) for applying a staining agent (45), which can selectively stain a product of a cancer-relating gene in a living cell a chromatic color, onto a group of living cells; an imaging unit (10) for imaging the group of living cells having the staining agent (45) applied thereto; and a determination unit (52) for determining the level of malignancy of cancerization of the group of living cells on the basis of the state of the stained expression pattern of the cancer-relating gene in the group of living cells in an image obtained by the aforementioned imaging.

Method for Predicting Effectiveness of Angiogenesis Inhibitor

The purpose of the present invention is to provide a method for predicting the effectiveness of an angiogenesis inhibitor in a subject suffering from a tumor. Provided is a method comprising a step of testing for the presence or absence of an a mutation or loss of expression of B-Raf and PTEN in a sample of tumor tissue from the subject. By using the presence or absence of or a mutation or loss of expression of B-Raf and PTEN as an indicator, this method enables the antitumor effectiveness of the angiogenesis inhibitor to be predicted without administering the angiogenesis inhibitor to the subject.

20230213529 · 2023-07-06 · ·

This disclosure relates to the field of mass spectrometry analysis. In some embodiments, the disclosure relates to compositions and methods for detecting and quantifying proteins in the AKT-mTOR pathway by immunoprecipitation enrichment followed by mass spectrometry analysis.

CACNA1H-derived tumor antigen polypeptide and use thereof

Provided are a tumor antigen polypeptide having the amino acid sequence as shown in SEQ ID NO: 2 or a variant thereof; a nucleic acid encoding the same; a nucleic acid construct, an expression vector, and a host cell containing the encoding nucleic acid; and an antigen presenting cell presenting the tumor antigen polypeptide on the cell surface and an immune effector cell thereof. Also provided is the use of the polypeptide, nucleic acid, antigen presenting cell or immune effector cell in the diagnosis, prevention and treatment of cancers.

METHODS OF TREATING DEMENTIA ASSOCIATED WITH ALZHEIMER'S DISEASE WITH PROTECTIVE PROTEIN/CATHEPSIN A (PPCA)

Methods are provided for the prognosis, diagnosis and treatment of various pathological states, including cancer, chemotherapy resistance and dementia associated with Alzheimer's disease. The methods provided herein are based on the discovery that various proteins with a high level of sialylation are shown herein to be associated with disease states, such as, cancer, chemotherapy resistance and dementia associated with Alzheimer's disease. Such methods provide a lysosomal exocytosis activity profile comprising one or more values representing lysosomal exocytosis activity. Also provided herein, is the discovery that low lysosomal sialidase activity is associated with various pathological states. Thus, the methods also provide a lysosomal sialidase activity profile, comprising one or more values representing lysosomal sialidase activity. A lysosomal sialidase activity profile is one example of a lysosomal exocytosis activity profile.

Method for detecting and/or characterising tumour cells and associated apparatus

The present invention relates to the field of biological diagnosis in oncology. It relates to a method and apparatus for detecting and/or characterizing tumor cells by detecting one or more elements of the tumor cell secretome, in particular one or more peptides or proteins, and, in particular, one or more tumor markers. The invention also relates to detecting and/or characterizing droplets of tumor cells and their method of preparation.

Monoclonal antibody specifically binding to MRS

The present invention relates to an anti-MRS monoclonal antibody and, more specifically, to an antibody or a fragment thereof characterized by specifically binding to a fragment represented by amino acid 861-900 of a human-derived methionyl-tRNA synthetase (MRS) protein set forth in SEQ ID NO:1, a method for producing the same, and a composition for diagnosing cancer comprising the same. The antibody or the fragment thereof of the present invention specifically binds to the human-derived MRS, and has no cross-reactivity with other proteins comprising the same ARS family. Therefore, as MRS detection is possible, the antibody or a fragment thereof can be effectively used for diagnosing MRS-related cancer.
