PPP1R1B-STARD3 fusion transcript was detected in 21.3% of primary human gastric cancers but not in adjacent matched normal gastric tissues.     ///    "Furthermore, expression of PPP1R1B-STARD3 fusion transcript enhanced the tumor growth of MKN-28 cells in athymic nude mice. "    ///    These findings show that PPP1R1B-STARD3 fusion transcript has a key role in subsets of gastric cancers through the activation of PI3K/AKT signaling.     ///    Multiple samples revealed expression of PPP1R1B-STARD3 fusion transcript.     ///    PPP1R1B-STARD3 chimeric fusion transcript in human gastric cancer promotes tumorigenesis through activation of PI3K/AKT signaling..     ///    "Based on reverse transcription PCR analysis of DNA, unlike other fusions described in gastric cancer, the PPP1R1B-STARD3 appears to be generated by RNA processing without chromosomal rearrangement. "    ///    The presence of PPP1R1B-STARD3 correlated with elevated levels of PPP1R1B mRNA.     ///    Overexpression of PPP1R1B-STARD3 in MKN-28 significantly increased cell proliferation and colony formation.
