FGF9/FGFR2 increase cell proliferation by activating ERK1/2, Rb/E2F1, and cell cycle pathways in mouse Leydig tumor cells.

Cancer Sci 2018 Nov 23;109(11):3503-3518. Epub 2018 Oct 23.

Department of Cell Biology and Anatomy, College of Medicine, National Cheng Kung University, Tainan, Taiwan.

Fibroblast growth factor 9 (FGF9) promotes cancer progression; however, its role in cell proliferation related to tumorigenesis remains elusive. We investigated how FGF9 affected MA-10 mouse Leydig tumor cell proliferation and found that FGF9 significantly induced cell proliferation by activating ERK1/2 and retinoblastoma (Rb) phosphorylations within 15 minutes. Subsequently, the expressions of E2F1 and the cell cycle regulators: cyclin D1, cyclin E1 and cyclin-dependent kinase 4 (CDK4) in G phase and cyclin A1, CDK2 and CDK1 in S-G /M phases were increased at 12 hours after FGF9 treatment; and cyclin B1 in G /M phases were induced at 24 hours after FGF9 stimulation, whereas the phosphorylations of p53, p21 and p27 were not affected by FGF9.

Transcriptome analysis to identify the Ras and Rap1 signal pathway genes involved in the response of TM3 Leydig cells exposed to zearalenone.

Environ Sci Pollut Res Int 2018 Nov 6;25(31):31230-31239. Epub 2018 Sep 6.

Key Laboratory of Zoonosis of Liaoning Province, College of Animal Science & Veterinary Medicine, Shenyang Agricultural University, Shenyang, 110866, China.

The mechanism of action of zearalenone (ZEA) in inducing germ cell tumors is unclear, and little is known about the change in the transcriptome of germ cells after ZEA exposure. To explore the molecular basis of the ZEA oncogene, we examined the median lethal concentration (50 μmol/L) and pro-apoptotic effect of ZEA on TM3 Leydig cells by MTT and TUNEL assay. Subsequently, we investigated the genetic changes in the transcriptome of TM3 Leydig cells exposed to 50 μmol/L ZEA. Read More

FEAT enhances INSL3 expression in testicular Leydig cells.

Genes Cells 2018 Nov 2;23(11):952-962. Epub 2018 Oct 2.

Department of Hematology and Oncology, Graduate School of Medicine, Kyoto University, Kyoto, Japan.

FEAT, the protein encoded by methyltransferase-like 13 (METTL13), is aberrantly upregulated in most human cancers and potently drives tumorigenesis in vivo; however, its role in normal tissues remains elusive. Immunoblotting has displayed weak FEAT expression in normal human tissues, including the testis. Here, we found that FEAT is expressed in fetal and adult Leydig cells in the testis. Read More
