SYF2 is thought to be a cell cycle regulator at the G1/S transition, which encodes a nuclear protein that interacts with cyclin D-type binding-protein 1. In the present study, we investigated the role of SYF2 in human glioma progression. Immunohistochemical and Western blot analyses were performed in human glioma tissues. High SYF2 expression (located in cell nuclei) was observed in 80 samples, and its level was correlated with the grade of malignancy. A strongly positive correlation was observed between SYF2 and Ki-67 expression (P < 0.01). More importantly, high expression of SYF2 was associated with a poor outcome. In vitro, after the release of U87 cell lines from serum starvation, the expression of SYF2 was upregulated, as well as PCNA and cyclin D1. In addition, knockdown of SYF2 by small interfering RNA transfection diminished the expression of PCNA, cyclin D1 and arrested cell growth at G1 phase. These results indicate that SYF2 in glioma is essential for cell proliferation; thus, targeting SYF2 or its downstream targets may lead to novel therapies for glioblastomas.

SYF2, also known as CCNDBP1-interactor or p29, is reported in pre-mRNA splicing and cell cycle progression. However, the role of SYF2 in esophageal squamous cell carcinoma (ESCC) development remains elusive. In the present study, Western blot and immunohistochemistry assays demonstrated that SYF2 was overexpressed in ESCC tumor tissues and cell lines. In addition, immunohistochemistry analysis revealed that SYF2 expression was positively correlated with tumor grade and predicted poor prognosis of ESCC. In vitro studies using serum starvation-refeeding experiment and SYF2-siRNA transfection assay demonstrated that SYF2 expression promoted proliferation of ESCC cells, while SYF2 knockdown led to decreased cell growth rate and colony formation resulted from growth arrest of cell cycle at G0/G1 phase. Furthermore, our results indicated that SYF2 can down-regulate the sensitivity of ESCC cells for cisplatin. Our findings for the first time supported that SYF2 might play an important role in the regulation of ESCC proliferation and would provide a novel therapeutic strategy against human ESCC.

SYF2 is reported to be as a cell cycle regulator at the G1/S transition and encodes a nuclear protein that interacts with cyclin-D-type binding protein 1. In our study, we investigated the role of SYF2 in human epithelial ovarian cancer (EOC) progression. Western blot and immunohistochemistry analysis displayed that SYF2 was overexpressed in EOC tissues and EOC cell lines. In addition, the immunoreactivity of SYF2 was positively correlated with tumor grade and Ki-67 expression. In vitro, serum starvation-refeeding experiment and SYF2-siRNA transfection assay demonstrated that the expression of SYF2 was promoted in the proliferative progression of EOC cells, while knockdown of SYF2 expression decreased and inhibited cell growth rate of EOC cells. With all the results, we support that SYF2 might contribute to EOC progression via modulation of proliferation in EOC cells and would provide a novel therapeutic target of human EOC.

SYF2, also known as p29/NTC31/CBPIN, encodes a nuclear protein that interacts with Cyclin D-type binding-protein 1. SYF2 has been reported to be involved in pre-mRNA splicing and cell cycle regulation. In the present study, we observed that SYF2 was obviously upregulated in HCC tumor tissues and cell lines, and its level was positively correlated with the tumor grade and Ki-67 expression, as well as poor prognosis of HCC. In vitro, using serum starvation-refeeding experiment, our results suggested that SYF2 was upregulated in proliferating HCC cells, and was positive correlated with the expression of PCNA and Cyclin D1. In addition, depletion of SYF2 decreased PCNA and Cyclin D1 levels. Accordingly, interference of SYF2 resulted in cells cycle arrest at G1/S phase in Huh7 HCC cells. Furthermore, we found that SYF2 might interact with Cyclin D1 and could confer doxorubicin resistance in HCC cells. These findings revealed that SYF2 might play a regulatory role in the proliferation of HCC cells. In summary, SYF2 may be a novel prognostic marker and serve as a potential therapeutic target in HCC.

SYF2, a known cell cycle regulator, is reported to be involved in cell cycle arrest by interacting with cyclin-D-type binding protein 1. In the present study, we investigated the role of SYF2 in human breast cancer (BC) progression. SYF2 was highly upregulated in BC tissues and cell lines, as per Western blot and immunohistochemistry analysis. The SYF2 expression level had a significant correlation with the tumor grade and Ki-67 expression. In vitro starvation-refeeding experiment and SYF2-siRNA transfection assay demonstrated that SYF2 could promote proliferation of BC cells, while SYF2 knockdown resulted in cells cycle arrest at G1/S phase, reducing the cell growth rate of BC cells. These results indicated that SYF2 promotes human BC progression by accelerating the BC cells' proliferation. SYF2 could be a novel therapeutic target in human BC therapies.
