SYT, a partner of SYT-SSX oncoprotein in synovial sarcomas, interacts with mSin3A, a component of histone deacetylase complex

Nuclear localization of SYT, SSX and the synovial sarcoma-associated SYT-SSX fusion proteins.

Synovial sarcoma is characterized by a prevalent chromosomal translocation, t(X;18)(p11;q11). As a result of this translocation the SYT gene on chromosome 18 fuses to either the SSX1 or the SSX2 gene on the X chromosome. In this study, we generated polyclonal antibodies against the SYT and SSX2 proteins. These antibodies specifically detected both these proteins and the SYT-SSX fusion proteins ...

Detection of SYT-SSX rearrangements in synovial sarcomas by real-time one-step RT-PCR.

Synovial sarcomas are aggressive tumors of adolescent and young adults that account for up to 10% of soft tissue sarcomas. Cytogenetically, they are characterized by translocation t(X;18), which is found in more than 95% of tumors. In most cases, it results in fusion of the SYT gene with the SSX1 or SSX2 gene, thus creating SYT-SSX1 or SYT-SSX2 rearrangement. The 2 types of gene fusion have bee...

Identification of two alternative fusion genes, SYT-SSX1 and SYT-SSX2, in t(X;18)(p11.2;q11.2)-positive synovial sarcomas.

Primary pericardial synovial sarcoma with detection of the chimeric transcript SYT-SSX.

We report a case of a 19-year-old woman with a primary pericardial synovial sarcoma that extended from the right ventricular free wall to the posterior aspect of the left anterior thoracic wall. Synovial sarcoma was diagnosed by the detection of the chimeric transcript SYT-SSX using reverse transcriptase-polymerase chain reaction (RT-PCR). This transcript is generated by reciprocal translocatio...

Prognostic implication of SYT-SSX fusion type in synovial sarcoma: a multi-institutional retrospective analysis in Japan.

The prognostic implication of SYT-SSX fusion type in synovial sarcomas is still controversial. The aim of this study is to clarify the prognostic impact of fusion type, in association with other clinical factors, in patients with synovial sarcoma in Japan. Data on 108 SYT-SSX fusion transcript-positive patients with synovial sarcoma, treated in 11 tertiary referral cancer centers in Japan, were...
