Horn cancer is one of the most important diseases in Zebu castrated male cattle. The objective of this study was to investigate the presence of p53 gene mutation in the blood of affected cattle and its value for early diagnosis and prognosis. The study was conducted on blood samples from 20 affected cattle and six healthy control cattle from Western India. Plasma samples were evaluated for the presence of p53 gene mutation using the polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP) technique and the results were correlated with the stage of cancer. Five of the 20 cases had stage I neoplasms, nine stage II and six stage III, based on histopathological examination. PCR-SSCP analysis revealed an aberrant pattern of DNA migration on polyacrylamide gel electrophoresis of DNA extracts from blood samples of six animals with stage II and stage III cancer. No mutation was identified in blood from cattle with stage I cancer or from healthy control cattle. These results suggest that PCR-SSCP detection of p53 gene mutation in blood has potential diagnostic and prognostic value, and indicate the need for further large-scale investigation.

D006733 Horns Either of the pair of hard processes, including ANTLERS, that consist of a BONE core surrounded by a middle KERATIN layer which is in turn covered by EPIDERMIS. They grow from the upper portion of the head of many RUMINANTS. Horn
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D016133 Polymerase Chain Reaction In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

D018807 Polymorphism, Single-Stranded Conformational Variation in a population's DNA sequence that is detected by determining alterations in the conformation of denatured DNA fragments. Denatured DNA fragments are allowed to renature under conditions that prevent the formation of double-stranded DNA and allow secondary structure to form in single stranded fragments. These fragments are then run through polyacrylamide gels to detect variations in the secondary structure that is manifested as an alteration in migration through the gels.
