Variant of mitochondrial ribosomal protein s28 (mrps28) gene is differentially expressed in response to radiation in a cervical carcinoma derived cell line

Abstract

<span style="mso-bidi-language:HI">Gene expression before and after radiation treatment (10 Gy) in a cervical carcinoma derived cell line SiHa was studied. Differential display performed on non-irradiated and irradiated cells (10 Gy) using a combination of 3 anchor primers and 16 arbitrary primers yielded 20 differentially expressed fragments. Differential expression of one of the fragments differentially expressed In the irradiated sample was also confirmed in Northern blots. Cloning and sequencing of the fragment revealed it to be similar to a splice variant of the MRPS28 gene. Reverse transcriptase polymerase chain

<span style="mso-bidi-language:HI">reaction (RT-PCR) was performed using primers designed to amplify the splice variant and confirmed the expression. In conclusion, the study shows that the splice variant kDec03 of the MRPS28 gene is differentially expressed in response to
