Disclosed herein is a method of treating a cancer in a subject having or suspected of having the cancer that has a mutated PREX2 expressed thereon. According to the embodiment of the present disclosure, the mutation is G258V, S1113R, E1346D or K400fs. The method includes the step of administering an effective amount of a composition to the subject, wherein the composition includes a therapeutic molecule for producing a polypeptide that exhibits a binding affinity to the mutated PREX2 protein expressed in the cancer in the subject.

Disclosed herein are methods of detecting or making a risk evaluation of a cancer that has a mutated PREX2 expressed thereon. The cancer may be a primary cancer, a metastatic cancer or a recurrent cancer. According to the embodiment of the present disclosure, the mutation is G258V, S1113R, E1346D or K400fs. Also disclosed herein are methods of treating the subject in need thereof.

Methods and compounds useful to treat diseases and conditions are provided. Methods of administering one or more microRNA-inhibitor compounds or one or more microRNA-enhancing compounds to cells, tissues, and/or subjects as a treatment for a disease or condition are provided.

Methods and compounds useful to treat diseases and conditions are provided. Methods of administering one or more microRNA-inhibitor compounds or one or more microRNA-enhancing compounds to cells, tissues, and/or subjects as a treatment for a disease or condition are provided.

Provided herein are cells, compositions, and related methods for improved cell growth. The expression of one or more of CBS, CTH, and GNMT genes is increased. In some embodiments, nucleic acid constructs, vectors, host cells and related compositions and methods for generating and selecting cysteine prototroph cells are provided.
