The present invention provides methods and kits for assessing whether a subject is afflicted with an FRα-expressing cancer, methods and kits for predicting the progression of ovarian cancer in a subject afflicted with an FRα-expressing cancer, methods and kits for assessing the level of risk that a subject will develop an FRα- expressing cancer, and methods of stratifying a subject with an FRα-expressing cancer into cancer therapy groups. The methods involve determining the level of folate receptor alpha (FRα) which is not bound to a cell in a sample derived from the subject and comparing this level with the level of FRα in a control sample.

The present invention features mammalian expression vectors that are useful for controlling DNA hypermutability in mammalian cell as well as the encoding polynucleotide sequences of vector sequences. In related aspects the invention features expression vectors and host cells comprising such polynucleotides. In other related aspects, the invention features transgenic cells expressing a mutator gene to enhance genome-wide mutagenesis, due to, for example, the presence of an exogenous mutator-encoding polynucleotide sequence. Further, the invention provides methods for using vector sequences that can remove the expression of such gene to restore DNA stability in a host cell.

Whole Genome Evolution Technology can be considered a broad tool for supporting the needs for scaleable manufacturing of therapeutic antibodies. Its random nature and in vivo mode of action separate this process from other complementary technologies, thus providing alternative solutions to improve a host cell's manufacturing performance. The speed with which a pre-existing production strain can be optimized makes this process suitable for satisfying the current need for rapid cell line optimization to produce faster growing cells exhibiting high titers of antibody at the preclinical, clinical or commercialization stage.

Dominant negative alleles of human mismatch repair genes can be used to generate hypermutable cells and organisms. By introducing these genes into cells and transgenic animals, new cell lines animal varieties with novel and useful properties can be prepared more efficiently than by relying on the natural rate of mutation. These methods are useful for generating genetic diversity within genes encoding for therapeutic antigens to produce altered polypeptides with enhanced antigenic and immunogenic activity. Moreover, these methods are useful for generating effective vaccines.

Dominant negative alleles of human mismatch repair genes can be used to generate hypermutable cells and organisms. By introducing these genes into cells and transgenic animals, new cell lines and animal varieties with novel and useful properties can be prepared more efficiently than by relying on the natural rate of mutation. These methods are useful for generating genetic diversity within immunoglobulins genes directed against an antigen of interest to produce altered antibodies with enhanced biochemical activity. Moreover, these methods are useful for generating antibody-producing cells with increased level of antibody production. The invention also provides methods for increasing the affinity of monoclonal antibodies and monoclonal antibodies with increased affinity.
