To develop more evidentiary support for EBV elicited alternative splicing of cellular mRNAs, we performed RT-nested-PCR analysis in the EBV-infected NPC-TW01 and HONE-1 stable lines (NA and HA), as well as paired EBV-negative controls (NP and HP), to identify alternative splicing events of TSG101. Here, TSG101 is linked to nasopharyngeal carcinoma.
