The present invention provides methods for selecting a therapy for, or for providing a treatment to, a patient having a cancer. The methods of the present invention comprise detecting the protein biomarkers c-Met, HGF, and EpCAM in cancer cells or cancerous tissues of a subject, and predicting the subject's responsiveness to treatment with a c-Met-targeted or other HGF-inhibitory treatment, thereby enabling the selection and administration of an effective therapeutic.

Disclosed herein are methods, kits, tests, and systems for detecting, predicting, monitoring, or ruling out preeclampsia in pregnant women. Also provided herein are novel diagnostic markers, methods of data analysis, assay formats, and kits employing such markers to improve one or more characteristics of a test for identifying or ruling out preeclampsia based on biomarkers from patient samples.

Methods and kits for determining, predicting, or diagnosing pulmonary artery hypertension (PAH) and for determining the efficacy of PAH therapy using biomarkers are provided.

A method for assessing the ability of a chemical substance or of a chemical composition to prevent or to slow the appearance of signs of aging of the human skin or of the lips or even to eliminate the signs; the method including: —a step a) of bringing the chemical substance or the chemical composition into contact with fibroblast cells of the “young” human dermis taken from a culture medium at the passage R6; —a step b) of bringing senescent cells of fibroblasts of the human dermis into contact with the cells of “young” fibroblasts from step a); and—a step c) of measuring the senescence input of the cells of “young” fibroblasts and of comparing it with a reference value.

Disclosed herein are methods, kits, tests, and systems for detecting, predicting, monitoring, or ruling out preeclampsia in pregnant women. Also provided herein are novel diagnostic markers, methods of data analysis, assay formats, and kits employing such markers to improve one or more characteristics of a test for identifying or ruling out preeclampsia based on biomarkers from patient samples.

Disclosed is an in vitro method for assessing whether a human subject has periodontitis. The method comprises detecting, in a sample of saliva from said subject, the concentrations of the proteins Hepatocyte Growth Factor (HGF) and Matrix Metalloproteinase 8 (MMP-8). Based on the concentrations determined, and adding age, and possibly other demographic markers such as sex and/or BMI, a testing value reflecting the joint concentrations is determined for said proteins, in combination with one or more demographic markers. The testing value is compared with a threshold value. The threshold reflects in the same manner the joint concentrations and the age, and possibly other demographic markers, as associated with periodontitis and may be seen as an upper limit of testing values as seen in a population of subjects without periodontitis. Thereby a testing value at or above the threshold value is indicative for periodontitis in said subject.

Biomarkers are provided that predict whether a human subject having a renal cell carcinoma is responsive to a combination therapy comprising lenvatinib or a pharmaceutically acceptable salt thereof (e.g., lenvatinib mesylate) and everolimus. The biomarkers, compositions, and methods described herein are useful in selecting appropriate treatment modalities for and treating a subject having, suspected of having, or at risk of developing a renal cell carcinoma.

Embodiments of the disclosure include methods and compositions related to selecting donor fibroblasts suitable for use in an allogeneic recipient individual. The methods and compositions encompass identifying expression of one or more human leukocyte antigens (HLA) and in some cases expression of one or more other factors, including regenerative factors.

An in vitro co-culture system comprising cancer-associated fibroblasts (CAFs) and cancer cells for producing and maintaining cancer stem cells and uses thereof for identifying agents capable of reducing cancer cell stemness. Also disclosed herein are a paracrine network through which CAFs facilitate production and/or maintenance of cancer stem cells and the use of components of such a paracrine network for prognosis purposes and for identifying cancer patients who are likely to respond to certain treatment.

Disclosed is an in vitro method for assessing the presence of gingivitis in a human subject. The method is based on the insight to determine a selection of three biomarker proteins. Accordingly, in a saliva sample of the subject the concentrations are measured of the proteins Hepatocyte growth factor (HGF) and Interleukin-1β (IL-1β), and at least one of C reactive protein (CRP) and Haemoglobin. Based on the concentrations as measured, a value is determined reflecting the joint concentrations for said proteins. This value is compared with a threshold value reflecting in the same manner the joint concentrations associated with the absence of gingivitis or periodontitis. The comparison allows to assessing whether the testing value is indicative of the presence of gingivitis in said subject. Thereby, typically, a testing value reflecting a joint concentration above the joint concentration reflected by the threshold, is indicative of the presence of gingivitis.
