| Function Description | In this study we report the LOH, LOI and methylation status of H19 and IGF2 genes in 29 invasive cervical carcinomas of different clinical stages. Fourteen (48%) and 13 (45%) tumours were heterozygous for H19 and IGF2 respectively. LOH for H19 and IGF2 genes were found in 2 of 14 (14%) and 3 of 13 (23%) informative tumours, respectively. LOI of H19 and IGF2 was detected in 2 of 12 (17%) and 5 of 10 (50%) tumours with no LOH, respectively. More interestingly, monoallelic expression of the otherwise silent H19 allele (allele switch) was observed in 2 of 12 (17%) tumours and biallelic expression of IGF2 was detected in one specimen of normal cervix adjacent to the tumour. The expressing H19 allele, and to a lower degree also the silent allele, were hypomethylated in tumours suggesting that demethylation of both H19 alleles may be associated with an early step of imprinting alteration. |
