Compositions and kits for exosome capture include an antibody specifically binding the human asparagine-linked glycosylation 6 homolog (ALG6). The compositions and kits may be employed in a method for diagnosing a disease or condition in a subject.

Treatment of testosterone deficiency in men by a precision medicine approach using a biomarker of activity of UGT2B17 that is involved in testosterone urinary elimination. By inhibiting UGT2B17, alone or in combination with administration of testosterone, testosterone deficiency in men can be treatable. Further, a method of dose selection for precise dosing of UGT2B17 substrate drugs is provided. Additionally, methods for safe dosing of pharmaceutical agents that undergo UGT2B17-mediated acyl glucuronidation are provided.

Provided herein are small molecule-inhibitors of site-specific O-glycosylation and the identification of such using cell-based fluorescent biosensors. Also provided herein are methods of treating kidney disease and cancer, such as breast cancer.

Compositions including a therapeutically effective amount of an HIV immunogen in combination with an agent that stimulates the Ras pathway, wherein the agent is not an aluminum salt, are disclosed. Methods are also disclosed for inducing an immune response to HIV, and/or to inhibit or treat HIV infection, in a subject, using an HIV immunogen and an agent that stimulates the Ras pathway. Methods also are disclosed for determining if an immunogenic composition will induce a protective response, and/or to determine if an immunogenic composition is of use to prevent or treat an HIV infection. The methods including determining if the immunogenic composition increases the level of one or more components of the Ras signaling pathway.

The present invention provides an -1,3 fucosyltransferase mutant having an increased expression level of soluble protein and increased activity, a DNA encoding the -1,3 fucosyltransferase mutant, a recombinant vector comprising the DNA encoding the -1,3 fucosyltransferase mutant, a host cell transformed with the recombinant DNA vector, an extract of the host cell, a method for producing 3-fucosyloligosaccharide, a method for preparing an -1,3 fucosyltransferase mutant, and a method for screening an -1,3 fucosyltransferase mutant. The -1,3 fucosyltransferase mutant of the present invention has a significantly increased soluble protein expression level and activity.

Disclosed are methods for treating, inhibiting, reducing, and/or preventing cancers (such as, for example melanoma) and/or metastasis (such as, for example metastatic melanoma) comprising administering to a subject a L-fucose and an anti-androgen therapy.

A method for distinguishing prostate cancer from prostatic hypertrophy using the method for analyzing PSA and an analysis kit of PSA are provided. An object of the present invention can be solved by being brought into contact a lectin having an affinity for -N-acetylgalactosamine residues with a sample possibly containing PSA, to determine an amount of PSA having an affinity for the lectin. A method for distinguishing prostate cancer from prostatic hypertrophy can be provided by this method.

The invention describes specific sialylated structures present on human stem cells and cell populations derived thereof. The invention is especially directed to methods to control the status of stem cells by observing changes in sialylation of the cells; and control of potential contaminations of biological materials; and reagents and methods used in connection with the cells in order to avoid alterations of the cell glycosylation by contaminating materials. The invention is further directed to novel stem cells, the glycosylation of which has been specifically altered.

The present invention provides methods of synthesizing trehalose analogues; methods of detecting mycobacteria, and trehalose analogues.

The present disclosure includes biomarkers, methods, devices, reagents, systems, and kits for evaluating and predicting lung cancer risk. In one aspect, the disclosure provides biomarkers that can be used alone or in various combinations to estimate or determine lung cancer risk. In another aspect, methods are provided for evaluating and predicting lung cancer risk in an individual, where the methods include detecting, in a biological sample from an individual, at least one biomarker value corresponding to at least one biomarker selected from the group of biomarkers provided in Table 6.
