Methods of treatment based on a breast cancer's biomolecule response to targeted treatment are provided. Expression levels of various biomolecules or histological assessment of infiltrating immune cells after initiation of human epidermal growth factor receptor 2 (HER2) targeted treatment can be used to determine whether a breast cancer will achieve a pathologic complete response. Based on likelihood of a pathologic complete response, a breast cancer can be treated accordingly.

Provided are a vesicle and the use thereof. The vesicle is an induced vesicle, and the sources thereof include stem cells or somatic cells, and the possessed markers include Syntaxin 4. Compared with an exosome in mesenchymal stem cells, the vesicle can specifically express Syntaxin 4 and can be used to distinguish characteristic markers of MSC-derived vesicles and exosomes. The vesicle can play a procoagulant effect in vitro, can improve the bleeding tendency of mice with hemophilia after in vivo injection, and can be used for the treatment of improving the bleeding tendency of hemophilia. In addition, the vesicle can be expelled through the skin and hair.

The invention generally relates to antibodies that bind to human folate receptor 1 and diagnostic assays for folate receptor 1-based therapies. Methods of using the antibodies to monitor therapy are further provided.

The present invention provides a screening method for a pain suppressor, which method comprises using FLRT3 to select a substance capable of inhibiting FLRT3 expression or a substance capable of inhibiting FLRT3 transport to the spinal cord. In addition, the present invention provides a pharmaceutical composition for prevention or treatment of pain, which pharmaceutical composition comprises, as an active ingredient, a substance capable of inhibiting FLRT3 expression or a substance capable of inhibiting FLRT3 transport to the spinal cord.

Methods for detecting the presence of proteins in a subject are described. The proteins detected can be indicative of acute myeloid leukemia (AML). The proteins can be particularly useful for monitoring minimal residual disease (MRD) in AML.

The present invention provides compounds and methods for the treatment of LFA-1 mediated diseases. In particular, LFA-1 antagonists are described herein and these antagonists are used in the treatment of LFA-1 mediated diseases. One aspect of the invention provides for diagnosis of an LFA-1 mediated disease and administration of a LFA-1 antagonist, after the patient is diagnosed with a LFA-1 mediated disease. In some embodiments, the LFA-1 mediated diseases treated are dry eye disorders. Also provided herein are methods for identifying compounds which are LFA-1 antagonists.

The present specification discloses SNAP-25 compositions, methods of making α-SNAP-25 antibodies that bind an epitope comprising a carboxyl-terminus at the P.sub.1 residue from the BoNT/A cleavage site scissile bond from a SNAP-25 cleavage product, α-SNAP-25 antibodies that bind an epitope comprising a carboxyl-terminus at the P.sub.1 residue from the BoNT/A cleavage site scissile bond from a SNAP-25 cleavage product, methods of detecting BoNT/A activity, and methods of detecting neutralizing α-BoNT/A antibodies.

Provided is a biomarker for bipolar disorder, comprising Syt7 gene and/or an expression product thereof. Also provided is use of the Syt7 gene and/or the expression product thereof in the preparing a medicament for treating bipolar disorder. By monitoring the Syt7 gene and/or the expression product thereof, medicaments for treating bipolar disorder can be screened, thus providing support for diagnosis and treatment targeting Syt7 molecules.

The present invention relates to novel antibodies or antigen-binding fragments thereof that specifically bind to TransMembrane 4 Superfamily Member 4 (TM4SF4). These antibodies or antigen-binding fragments thereof exhibit proliferation inhibitory activity of cancer cells so as to effectively prevent or treat cancer, and reduce the self-renewal ability of cancer stem cells to be usefully used even in the treatments of cancer with a poor prognosis in conventional anticancer treatments.

Provided are methods for detecting or isolating circulating tumor cells (CTCs) in a subject. The methods may include detecting the expression of at least one epithelial mesenchymal transition (EMT) biomarker. Further provided are kits for detecting or isolating CTCs. The kits may include antibodies to at least one EMT biomarker. Further provided are methods of predicting the responsiveness of a subject to a cancer drug, methods of targeting delivery of a cancer drug in a subject, methods of providing a cancer prognosis to a subject, and methods for following the progress of cancer in a subject.
