Quantitation of enhanced expression of ras-oncogene product (p21) in childhood renal tumours. 1991

Christie Hospital and Holt Radium Institute, Manchester, England.

A monoclonal antibody, RAP-5, raised against the 21,000d ras-oncogene product, p21, was used in an immunoperoxidase staining procedure to study the expression of p21 in normal children's and foetal kidneys, pre-malignant lesions and benign and malignant childhood renal tumours with good, moderate or poor prognosis. ras-p21 was expressed in both normal and foetal kidneys but its distribution in renal tumours differed markedly (p less than 0.01). A quantitative liquid competition radioimmunoassay (RIA) was used to determine ras-p21 level in tissue homogenates. The results were expressed as pg of ras-p21 per microgram protein of tissue extract. There were significant differences in the levels of ras-p21 among various renal tissue extracts (p less than 0.05). Generally it emerged that the amount of ras-p21 was greater in both malignant renal tumours and foetal kidneys compared to normal kidneys, pre-malignant lesions and benign renal tumours.

D009396	Wilms Tumor	A malignant kidney tumor, caused by the uncontrolled multiplication of renal stem (blastemal), stromal (STROMAL CELLS), and epithelial (EPITHELIAL CELLS) elements. However, not all three are present in every case. Several genes or chromosomal areas have been associated with Wilms tumor which is usually found in childhood as a firm lump in a child's side or ABDOMEN.

D011863	Radioimmunoassay	Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.	Radioimmunoassays
D011905	Genes, ras	Family of retrovirus-associated DNA sequences (ras) originally isolated from Harvey (H-ras, Ha-ras, rasH) and Kirsten (K-ras, Ki-ras, rasK) murine sarcoma viruses. Ras genes are widely conserved among animal species and sequences corresponding to both H-ras and K-ras genes have been detected in human, avian, murine, and non-vertebrate genomes. The closely related N-ras gene has been detected in human neuroblastoma and sarcoma cell lines. All genes of the family have a similar exon-intron structure and each encodes a p21 protein.
