Abstract
Abstract DNA sequences coding for at least one MIS-like polypeptide, recombinant DNA molecules comprising such sequences, hosts comprising such sequences and processes for producing such polypeptides in hosts transformed with those DNA sequences. The MIS-like polypeptides are useful in the treatment of ovarian cancer and other susceptible cancers.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
13 words
A DNA sequence selected from the group consisting of the DNA sequences ##STR3##
Claim 2
Dependent Claim
13 words
A DNA sequence selected from the group consisting of the DNA sequences ##STR3##
Claim 3
Dependent Claim
92 words
A recombinant DNA molecule comprising a DNA sequence selected from the group consisting of: (a) the DNA sequences of claim 1; (b) DNA sequences that hybridize to any of the DNA sequences of (a) and that code for a polypeptide displaying the biological or immunological activity of a human or bovine MIS protein; and (c) DNA sequences which are degenerate as a result of the genetic code to the DNA sequences defined above and which code for a polypeptide displaying the biological or immunological activity of a human or bovine MIS protein.
Claim 4
Dependent Claim
25 words
The recombinant DNA molecule according to claim 2, wherein said DNA sequence is operatively linked to an expression control sequence in the recombinant DNA molecule.
Claim 5
Dependent Claim
95 words
The recombinant DNA molecule according to claim 3, wherein said expression control sequence is selected from the group consisting of the early and late promoters of SV40, the lac system, the tac system, the trc system, the trp system, adenovirus major late promoter, major operator and promotor regions of phage λ, the control regions of fd coat protein, the promoter of 3-phosphoglycerate kinase or other glycolytic enzymes, the promoters of acid phosphatase, the promoters of yeast α-mating factors, and other sequences which control the expression of genes of prokaryotic or eukaryotic cells or their viruses.
