The present invention relates to methods of treating ovarian cancer in a subject by administering to the subject by evaluating the subject's expression levels of specific biomarkers or angiogenic an anti-activin-A compound, such as an anti-activin-A antibody or an activin-A-binding receptor. In some embodiments, at least two compounds are administered to the subject, where the first compound is an anti-activin A compound, and the second compound is a chemotherapeutic compound, for example capecitabine. The invention further relates to methods of identifying subjects for treatment factors.

In some aspects, the disclosure relates to single-arm ActRIIA heteromultimers and single-arm ActRIIB heteromultimers and methods of using such heteromultimers to treat, prevent, or reduce the progression rate and/or severity of pulmonary hypertension (PH), particularly treating, preventing or reducing the progression rate and/or severity of one or more PH-associated complications. The disclosure also provides methods of using a single-arm ActRIIA heteromultimer or single-arm ActRIIB heteromultimer to treat, prevent, or reduce the progression rate and/or severity of a variety of conditions including, but not limited to, pulmonary vascular remodeling, pulmonary fibrosis, and right ventricular hypertrophy. The disclosure further provides methods of using single-arm ActRIIA heteromultimers and single-arm ActRIIB heteromultimers to reduce right ventricular systolic pressure in a subject in need thereof.

Provided herein are methods for treating anemia in a subject in need thereof, comprising administering to the subject an activin receptor type IIB (ActRIIB) ligand trap and administering to the subject fedratinib. Specifically, the method comprising taking a measurement of hemoglobin (Hgb) level in the subject before and after the administration.

Provided herein are methods for treating anemia in a subject in need thereof, comprising administering to the subject an activin receptor type IIB (ActRIIB) ligand trap and administering to the subject fedratinib. Specifically, the method comprising taking a measurement of hemoglobin (Hgb) level in the subject before and after the administration.

Methods of treating subjects having diseases, disorders, or conditions, including disorders associated with cholesterol homeostasis, responsive to agents modulating Kupffer cell function, including methods of administration and dosing regimens associated therewith, are provided. Methods of treating subjects having liver diseases, disorders, or conditions, including non-alcoholic steatohepatitis and non-alcoholic fatty liver disease, with an IL-10 agent are also provided.

In certain aspects, the present invention provides compositions and methods for increasing thermogenic adipocytes (e.g., brown adipocytes or other UCP-1 expressing adipocytes) by administering an antagonist of an ActRIIB signaling pathway. Examples of such antagonists include ActRIIB polypeptides, anti-ActRIIB antibodies, anti-myostatin antibodies, anti-GDF3 antibodies, anti-Noda1, anti-activin, and anti-GDF11 antibodies. A variety of metabolic and other disorders may be treated by causing an increase in thermogenic adipocytes.

The invention relates to methods of protecting against chronic stress in a subject and treating stress sensitive disorders in a subject by antagonizing ghrelin or ghrelin receptor.

Disclosed herein are compositions and methods for increasing visual acuity in patients in need thereof and for treating vascular disorders of the eye.

In some aspects, the disclosure relates to GDF/BMP antagonists and methods of using GDF/BMP antagonists to treat, prevent, or reduce the progression rate and/or severity of pulmonary hypertension (PH), particularly treating, preventing or reducing the progression rate and/or severity of one or more PH-associated complications. The disclosure also provides methods of using a GDF/BMP antagonist to treat, prevent, or reduce the progression rate and/or severity of a variety of conditions including, but not limited to, pulmonary vascular remodeling, pulmonary fibrosis, and right ventricular hypertrophy. The disclosure further provides methods of using a GDF/BMP antagonist to reduce right ventricular systolic pressure in a subject in need thereof.

Provided herein are methods for the repopulation of organs and tissues, such as the liver, using modified cells that express a transcription coactivation factor-ligand binding domain fusion protein, such as a YAP-ERT2 fusion protein. Also provided are compositions, including nucleic acid molecules that encode a YAP-ERT2 fusion protein, YAP-ERT2 fusion polypeptides, and cells containing nucleic acid molecules that encode a YAP-ERT2 fusion protein.
